+# 1.22.2 2021-08-07
+
+Breaking changes
+
+- aregister no longer hides future transactions by default.
+  This is a consequence of the fix for 
+  [#1638](https://github.com/simonmichael/hledger/issues/1638). 
+  It makes aregister consistent, so we think it's a reasonable change.
+  So if you have future-dated transactions in your journal which you
+  don't want reported, you now must exclude them with `-e tomorrow` or
+  `date:-tomorrow` in the command, as with other reports.
+  (Stephen Morgan)
+
+Improvements
+
+- Timedot format's doc has been rewritten.
+
+Fixes
+
+- Make balance assignments in forecasted transactions work again
+  (broken in 1.22.1).
+  Forecast transactions are now generated early and processed
+  in the same way as other transactions.
+  ([#1638](https://github.com/simonmichael/hledger/issues/1638), Stephen Morgan)
+
+- aregister preserves the order of same-day transactions again
+  (broken in 1.22.1).

 Fixes
+
+- `cur:` and `amt:` queries now match the original amounts before
+  valuation and cost conversion, as they did before hledger 1.22. We
+  believe this is the more useful behaviour in practice. 
+  (#1625, Stephen Morgan)
+
+- Queries now work better with `register --related`, no longer showing
+  duplicate postings when more than one posting in a transaction is
+  matched. 
+  (#1629, Stephen Morgan)
+
+- Valuation now works with `register --related`. 
+  (#1630, Stephen Morgan)
+
+- Auto posting rules now also see inferred amounts,
+  not just explicit amounts. 
+  (#1412, Stephen Morgan)
+
+- The aregister command now properly ignores a `depth:` argument. 
+  It might now also behave more correctly with valuation or `--txn-dates`.

 15 TIMEDOT FORMAT
 *****************
 
-hledger's human-friendly time logging format.
+'timedot' format is hledger's human-friendly time logging format.
+Compared to 'timeclock' format, it is
 
-   Timedot is a plain text format for logging dated, categorised
-quantities (of time, usually), supported by hledger.  It is convenient
-for approximate and retroactive time logging, eg when the real-time
-clock-in/out required with a timeclock file is too precise or too
-interruptive.  It can be formatted like a bar chart, making clear at a
-glance where time was spent.
+   * convenient for quick, approximate, and retroactive time logging
+   * readable: you can see at a glance where time was spent.
 
-   Though called "timedot", this format is read by hledger as
-commodityless quantities, so it could be used to represent dated
-quantities other than time.  In the docs below we'll assume it's time.
+   A timedot file contains a series of day entries, which might look
+like this:
 
-   A timedot file contains a series of day entries.  A day entry begins
-with a non-indented hledger-style simple date (Y-M-D, Y/M/D, Y.M.D..)
-Any additional text on the same line is used as a transaction
-description for this day.
+2021-08-04
+hom:errands          .... ....
+fos:hledger:timedot  ..         ; docs
+per:admin:finance    
 
-   This is followed by optionally-indented timelog items for that day,
-one per line.  Each timelog item is a note, usually a
-hledger:style:account:name representing a time category, followed by two
-or more spaces, and a quantity.  Each timelog item generates a hledger
-transaction.
+   hledger reads this as three time transactions on this day, with each
+dot representing a quarter-hour spent:
 
-   Quantities can be written as:
+$ hledger -f a.timedot print   # .timedot file extension activates the timedot reader
+2021-08-04 *
+    (hom:errands)            2.00
 
-   * dots: a sequence of dots (.)  representing quarter hours.  Spaces
-     may optionally be used for grouping.  Eg: ....  ..
+2021-08-04 *
+    (fos:hledger:timedot)    0.50
 
-   * an integral or decimal number, representing hours.  Eg: 1.5
+2021-08-04 *
+    (per:admin:finance)      0
 
-   * an integral or decimal number immediately followed by a unit symbol
-     's', 'm', 'h', 'd', 'w', 'mo', or 'y', representing seconds,
-     minutes, hours, days weeks, months or years respectively.  Eg: 90m.
-     The following equivalencies are assumed, currently: 1m = 60s, 1h =
-     60m, 1d = 24h, 1w = 7d, 1mo = 30d, 1y=365d.
+   A day entry begins with a date line:
 
-   There is some flexibility allowing notes and todo lists to be kept
-right in the time log, if needed:
+   * a non-indented *simple date* (Y-M-D, Y/M/D, or Y.M.D).
 
-   * Blank lines and lines beginning with '#' or ';' are ignored.

-     items taking no time, which will not appear in balance reports by
-     default.  (Add -E to see them.)
+   * a common *transaction description* for this day
+   * a common *transaction comment* for this day, after a semicolon
+     (';').
 
-   * Org mode headlines (lines beginning with one or more '*' followed
-     by a space) can be used as date lines or timelog items (the stars
-     are ignored).  Also all org headlines before the first date line
-     are ignored.  This means org users can manage their timelog as an
-     org outline (eg using org-mode/orgstruct-mode in Emacs), for
-     organisation, faster navigation, controlling visibility etc.
+   After the date line are zero or more optionally-indented time
+transaction lines, consisting of:
 
-   Examples:
+   * an *account name* - any word or phrase, usually a hledger-style
+     account name.
+   * *two or more spaces* - a field separator, required if there is an
+     amount (as in journal format).
+   * a *timedot amount* - dots representing quarter hours, or a number
+     representing hours.
+   * an optional *comment* beginning with semicolon.  This is ignored.
 
+   In more detail, timedot amounts can be:
+
+   * *dots*: zero or more period characters, each representing one
+     quarter-hour.  Spaces are ignored and can be used for grouping.
+     Eg: '.... ..'
+
+   * a *number*, representing hours.  Eg: '1.5'
+
+   * a *number immediately followed by a unit symbol* 's', 'm', 'h',
+     'd', 'w', 'mo', or 'y', representing seconds, minutes, hours, days
+     weeks, months or years.  Eg '1.5h' or '90m'.  The following
+     equivalencies are assumed:
+     '60s' = '1m', '60m' = '1h', '24h' = '1d', '7d' = '1w', '30d' =
+     '1mo', '365d' = '1y'.  (This unit will not be visible in the
+     generated transaction amount, which is always in hours.)

 NAME
        This  is  the  command-line  interface (CLI) for the hledger accounting
        tool.  Here we also describe hledger's concepts and file formats.  This
-       manual is for hledger 1.22.1.
-
-SYNOPSIS
-       hledger
-
-       hledger [-f FILE] COMMAND [OPTIONS] [ARGS]
-
-       hledger [-f FILE] ADDONCMD -- [OPTIONS] [ARGS]
-
-DESCRIPTION
-       hledger  is  a  reliable,  cross-platform  set of programs for tracking
-       money, time, or any other commodity, using double-entry accounting  and
-       a  simple,  editable  file  format.  hledger is inspired by and largely
-       compatible with ledger(1).
-
-       The basic function of the hledger CLI is to  read  a  plain  text  file
-       describing financial transactions (in accounting terms, a general jour-
-       nal) and print useful reports on standard output,  or  export  them  as
-       CSV.   hledger can also read some other file formats such as CSV files,
-       translating them to journal format.  Additionally, hledger lists  other
-       hledger-*  executables found in the user's $PATH and can invoke them as
-       subcommands.
-
-       hledger reads data from one or more files  in  hledger  journal,  time-
-       clock,  timedot,  or  CSV format specified with -f, or $LEDGER_FILE, or
-       $HOME/.hledger.journal          (on          windows,           perhaps
-       C:/Users/USER/.hledger.journal).  If using $LEDGER_FILE, note this must
-       be a real environment variable, not a shell variable.  You can  specify
-       standard input with -f-.
-
-       Transactions  are  dated movements of money between two (or more) named
-       accounts, and are recorded with journal entries like this:
-
-              2015/10/16 bought food
-               expenses:food          $10
-               assets:cash
-
-       Most users use a text editor to edit the journal, usually with an  edi-
-       tor mode such as ledger-mode for added convenience.  hledger's interac-
-       tive add command is another way to record  new  transactions.   hledger
-       never changes existing transactions.
-
-       To  get  started,  you  can  either save some entries like the above in
-       ~/.hledger.journal, or run hledger add and follow  the  prompts.   Then
-       try  some  commands like hledger print or hledger balance.  Run hledger
-       with no arguments for a list of commands.
-
-OPTIONS
-   General options

-
-       -NUM --depth=NUM
-              hide/aggregate accounts or postings more than NUM levels deep
-
-       -E --empty
-              show  items with zero amount, normally hidden (and vice-versa in
-              hledger-ui/hledger-web)
-
-       -B --cost
-              convert amounts to their cost/selling amount at transaction time
-
-       -V --market
-              convert  amounts to their market value in default valuation com-
-              modities
-
-       -X --exchange=COMM
-              convert amounts to their market value in commodity COMM
-
-       --value
-              convert amounts to cost or  market  value,  more  flexibly  than
-              -B/-V/-X
-
-       --infer-market-prices
-              use  transaction  prices  (recorded  with @ or @@) as additional
-              market prices, as if they were P directives
-
-       --auto apply automated posting rules to modify transactions.
-
-       --forecast
-              generate future transactions from  periodic  transaction  rules,
-              for  the  next 6 months or till report end date.  In hledger-ui,
-              also make ordinary future transactions visible.
-
-       --color=WHEN (or --colour=WHEN)
-              Should color-supporting commands use ANSI color  codes  in  text
-              output.   'auto' (default): whenever stdout seems to be a color-
-              supporting terminal.  'always' or 'yes': always, useful eg  when
-              piping  output  into  'less  -R'.   'never'  or  'no': never.  A
-              NO_COLOR environment variable overrides this.
-
-       When a reporting option appears more than once in the command line, the
-       last one takes precedence.
-
-       Some reporting options can also be written as query arguments.
-
-   Command options
-       To  see  options  for  a particular command, including command-specific
-       options, run: hledger COMMAND -h.
-
-       Command-specific options must be written after the  command  name,  eg:
-       hledger print -x.
-
-       Additionally,  if  the  command  is  an add-on, you may need to put its
-       options after a double-hyphen, eg: hledger ui -- --watch.  Or, you  can
-       run the add-on executable directly: hledger-ui --watch.
-
-   Command arguments
-       Most  hledger  commands  accept arguments after the command name, which
-       are often a query, filtering the data in some way.
-
-       You can save a set of command line options/arguments  in  a  file,  and
-       then  reuse  them by writing @FILENAME as a command line argument.  Eg:
-       hledger bal @foo.args.  (To prevent this, eg if you  have  an  argument
-       that  begins  with  a literal @, precede it with --, eg: hledger bal --
-       @ARG).
-
-       Inside the argument file, each line should contain just one  option  or
-       argument.  Avoid the use of spaces, except inside quotes (or you'll see
-       a confusing error).  Between a flag and its argument, use =  (or  noth-
-       ing).  Bad:
-
-              assets depth:2
-              -X USD
-
-       Good:
-
-              assets
-              depth:2
-              -X=USD
-
-       For  special characters (see below), use one less level of quoting than
-       you would at the command prompt.  Bad:
-
-              -X"$"
-
-       Good:
-
-              -X$
-
-       See also: Save frequently used options.
-
-   Special characters
-   Single escaping (shell metacharacters)
-       In shell command lines, characters significant to your shell - such  as
-       spaces,  <, >, (, ), |, $ and \ - should be "shell-escaped" if you want
-       hledger to see them.  This is done by enclosing them in single or  dou-
-       ble  quotes,  or  by  writing  a backslash before them.  Eg to match an
-       account name containing a space:
-
-              $ hledger register 'credit card'
-
-       or:
-
-              $ hledger register credit\ card
-
-       Windows users should keep in mind that cmd treats  single  quote  as  a
-       regular  character,  so  you should be using double quotes exclusively.
-       PowerShell treats both single and double quotes as quotes.
-
-   Double escaping (regular expression metacharacters)
-       Characters significant in regular expressions (described below) -  such
-       as  .,  ^,  $, [, ], (, ), |, and \ - may need to be "regex-escaped" if
-       you don't want them to be interpreted by hledger's  regular  expression
-       engine.   This  is  done  by writing backslashes before them, but since
-       backslash is typically also a shell metacharacter, both  shell-escaping
-       and  regex-escaping will be needed.  Eg to match a literal $ sign while
-       using the bash shell:
-
-              $ hledger balance cur:'\$'
-
-       or:
-
-              $ hledger balance cur:\\$
-
-   Triple escaping (for add-on commands)
-       When you use hledger to  run  an  external  add-on  command  (described
-       below),  one  level of shell-escaping is lost from any options or argu-
-       ments intended for by the add-on command, so those need an extra  level
-       of  shell-escaping.   Eg to match a literal $ sign while using the bash
-       shell and running an add-on command (ui):
-
-              $ hledger ui cur:'\\$'
-
-       or:
-
-              $ hledger ui cur:\\\\$
-
-       If you wondered why four backslashes, perhaps this helps:
-
-
-       unescaped:        $
-       escaped:          \$
-       double-escaped:   \\$
-       triple-escaped:   \\\\$
-
-       Or, you can avoid the extra escaping by running the  add-on  executable
-       directly:
-
-              $ hledger-ui cur:\\$
-
-   Less escaping
-       Options and arguments are sometimes used in places other than the shell
-       command line, where shell-escaping is not needed, so there  you  should
-       use one less level of escaping.  Those places include:
-
-       o an @argumentfile
-
-       o hledger-ui's filter field
-
-       o hledger-web's search form
-
-       o GHCI's prompt (used by developers).
-
-   Unicode characters
-       hledger is expected to handle non-ascii characters correctly:
-
-       o they  should  be  parsed  correctly in input files and on the command
-         line, by all hledger tools (add, iadd, hledger-web's  search/add/edit
-         forms, etc.)
-
-       o they  should  be  displayed  correctly  by all hledger tools, and on-
-         screen alignment should be preserved.
-
-       This requires a well-configured environment.  Here are some tips:
-
-       o A system locale must be configured, and  it  must  be  one  that  can
-         decode the characters being used.  In bash, you can set a locale like
-         this: export LANG=en_US.UTF-8.  There are some more details in  Trou-
-         bleshooting.   This step is essential - without it, hledger will quit
-         on encountering a non-ascii character (as with all GHC-compiled  pro-
-         grams).
-
-       o your  terminal  software  (eg  Terminal.app, iTerm, CMD.exe, xterm..)
-         must support unicode
-
-       o the terminal must be using a font which includes the required unicode
-         glyphs
-
-       o the  terminal should be configured to display wide characters as dou-
-         ble width (for report alignment)
-
-       o on Windows, for best results you should run hledger in the same  kind
-         of  environment in which it was built.  Eg hledger built in the stan-
-         dard CMD.EXE environment (like the binaries  on  our  download  page)
-         might  show  display  problems when run in a cygwin or msys terminal,
-         and vice versa.  (See eg #961).
-
-   Regular expressions
-       hledger uses regular expressions in a number of places:
-
-       o query terms, on the command line and in the hledger-web search  form:
-         REGEX, desc:REGEX, cur:REGEX, tag:...=REGEX
-
-       o CSV rules conditional blocks: if REGEX ...
-
-       o account  alias  directives  and options: alias /REGEX/ = REPLACEMENT,
-         --alias /REGEX/=REPLACEMENT
-
-       hledger's regular expressions come from  the  regex-tdfa  library.   If
-       they're  not doing what you expect, it's important to know exactly what
-       they support:
-
-       1. they are case insensitive
-
-       2. they are infix matching (they do not need to match the entire  thing
-          being matched)
-
-       3. they are POSIX ERE (extended regular expressions)
-
-       4. they also support GNU word boundaries (\b, \B, \<, \>)
-
-       5. they  do  not support backreferences; if you write \1, it will match
-          the digit 1.  Except when doing  text  replacement,  eg  in  account
-          aliases,  where backreferences can be used in the replacement string
-          to reference capturing groups in the search regexp.
-
-       6. they do not support mode modifiers ((?s)),  character  classes  (\w,
-          \d), or anything else not mentioned above.
-
-       Some things to note:
-
-       o In  the  alias directive and --alias option, regular expressions must
-         be enclosed in forward  slashes  (/REGEX/).   Elsewhere  in  hledger,
-         these are not required.
-
-       o In  queries,  to match a regular expression metacharacter like $ as a
-         literal character, prepend a backslash.  Eg  to  search  for  amounts
-         with the dollar sign in hledger-web, write cur:\$.
-
-       o On  the command line, some metacharacters like $ have a special mean-
-         ing to the shell and so must be escaped at least once more.  See Spe-
-         cial characters.
-
-ENVIRONMENT
-       LEDGER_FILE The journal file path when not specified with -f.  Default:
-       ~/.hledger.journal (on  windows,  perhaps  C:/Users/USER/.hledger.jour-
-       nal).
-
-       A  typical  value  is  ~/DIR/YYYY.journal,  where DIR is a version-con-
-       trolled finance directory and YYYY is the current year.  Or  ~/DIR/cur-
-       rent.journal, where current.journal is a symbolic link to YYYY.journal.
-
-       On Mac computers, you can set this and other environment variables in a
-       more  thorough  way that also affects applications started from the GUI
-       (say,  an  Emacs  dock  icon).   Eg  on  MacOS  Catalina   I   have   a
-       ~/.MacOSX/environment.plist file containing
-
-              {
-                "LEDGER_FILE" : "~/finance/current.journal"
-              }
-
-       To see the effect you may need to killall Dock, or reboot.
-
-       COLUMNS  The  screen  width used by the register command.  Default: the
-       full terminal width.
-
-       NO_COLOR If this variable exists with any value, hledger will  not  use
-       ANSI   color   codes   in   terminal   output.    This   overrides  the
-       --color/--colour option.
-
-DATA FILES
-       hledger reads transactions from one or more data  files.   The  default
-       data  file  is  $HOME/.hledger.journal  (or  on Windows, something like
-       C:/Users/USER/.hledger.journal).
-
-       You can override this with the $LEDGER_FILE environment variable:
-
-              $ setenv LEDGER_FILE ~/finance/2016.journal
-              $ hledger stats
-
-       or with one or more -f/--file options:
-
-              $ hledger -f /some/file -f another_file stats
-
-       The file name - means standard input:
-
-              $ cat some.journal | hledger -f-
-
-   Data formats
-       Usually the data file is in hledger's journal format, but it can be  in
-       any of the supported file formats, which currently are:
-
-
-       Reader:    Reads:                                    Used  for  file  exten-
-                                                            sions:
-       -----------------------------------------------------------------------------
-       journal    hledger journal files and  some  Ledger   .journal   .j  .hledger
-                  journals, for transactions                .ledger
-       time-      timeclock  files, for precise time log-   .timeclock
-       clock      ging
-       timedot    timedot  files,  for  approximate  time   .timedot
-                  logging
-       csv        comma/semicolon/tab/other-separated       .csv .ssv .tsv
-                  values, for data import
-
-       These formats are described in their own sections, below.
-
-       hledger detects the format automatically based on the  file  extensions
-       shown  above.   If  it  can't  recognise the file extension, it assumes
-       journal format.  So for non-journal files,  it's  important  to  use  a
-       recognised file extension, so as to either read successfully or to show
-       relevant error messages.
-
-       You can also force a specific reader/format by prefixing the file  path
-       with the format and a colon.  Eg, to read a .dat file as csv format:
-
-              $ hledger -f csv:/some/csv-file.dat stats
-
-       Or to read stdin (-) as timeclock format:
-
-              $ echo 'i 2009/13/1 08:00:00' | hledger print -ftimeclock:-
-
-   Multiple files
-       You  can specify multiple -f options, to read multiple files as one big
-       journal.  There are some limitations with this:
-
-       o most directives do not affect sibling files
-
-       o balance assertions will not see any account  balances  from  previous
-         files
-
-       If you need either of those things, you can
-
-       o use a single parent file which includes the others
-
-       o or  concatenate  the files into one before reading, eg: cat a.journal
-         b.journal | hledger -f- CMD.
-
-   Strict mode
-       hledger checks input files for valid data.  By default, the most impor-
-       tant  errors  are  detected,  while  still accepting easy journal files
-       without a lot of declarations:
-
-       o Are the input files parseable, with valid syntax ?
-
-       o Are all transactions balanced ?
-
-       o Do all balance assertions pass ?
-
-       With the -s/--strict flag, additional checks are performed:
-
-       o Are all accounts posted to, declared  with  an  account  directive  ?
-         (Account error checking)
-
-       o Are all commodities declared with a commodity directive ?  (Commodity
-         error checking)
-
-       o Are all commodity conversions declared explicitly ?
-
-       You can also use the check command to run  these  and  some  additional
-       checks.
-
-TIME PERIODS
-   Smart dates
-       hledger's user interfaces accept a flexible "smart date" syntax.  Smart
-       dates allow some english words, can be relative to  today's  date,  and
-       can have less-significant date parts omitted (defaulting to 1).
-
-       Examples:
-
-
-       2004/10/1,   2004-01-01,   exact date, several separators allowed.   Year
-       2004.9.1                   is 4+ digits, month is 1-12, day is 1-31
-       2004                       start of year
-       2004/10                    start of month
-       10/1                       month and day in current year
-       21                         day in current month
-       october, oct               start of month in current year
-       yesterday, today, tomor-   -1, 0, 1 days from today
-       row
-       last/this/next             -1, 0, 1 periods from the current period
-       day/week/month/quar-
-       ter/year
-       20181201                   8 digit YYYYMMDD with valid year month and day
-       201812                     6 digit YYYYMM with valid year and month
-
-       Counterexamples  -  malformed  digit  sequences  might  give surprising
-       results:
-
-
-       201813        6 digits with an  invalid  month  is  parsed  as  start  of
-                     6-digit year
-       20181301      8  digits  with  an  invalid  month  is  parsed as start of
-                     8-digit year
-       20181232      8 digits with an invalid day gives an error
-       201801012     9+ digits beginning with a valid YYYYMMDD gives an error
-
-
-   Report start & end date
-       By default, most hledger reports will show the full span of time repre-
-       sented by the journal data.  The report start date will be the earliest
-       transaction or posting date, and the report end date will be the latest
-       transaction, posting, or market price date.
-
-       Often  you  will  want  to see a shorter time span, such as the current
-       month.  You can specify a  start  and/or  end  date  using  -b/--begin,
-       -e/--end, -p/--period or a date: query (described below).  All of these
-       accept the smart date syntax.
-
-       Some notes:
-
-       o As in Ledger, end dates are exclusive, so you need to write the  date
-         after the last day you want to include.
-
-       o As  noted  in reporting options: among start/end dates specified with
-         options, the last (i.e.  right-most) option takes precedence.
-
-       o The effective report start and end dates are the intersection of  the
-         start/end  dates  from options and that from date: queries.  That is,
-         date:2019-01 date:2019 -p'2000 to  2030'  yields  January  2019,  the
-         smallest common time span.
-
-       o A  report  interval  (see  below)  will  adjust start/end dates, when
-         needed, so that they fall on subperiod boundaries.
-
-       Examples:
-
-
-       -b 2016/3/17       begin on St. Patrick's day 2016
-       -e 12/1            end  at  the  start  of  december  1st of the current year
-                          (11/30 will be the last date included)
-       -b thismonth       all transactions on or after the 1st of the current month
-       -p thismonth       all transactions in the current month
-       date:2016/3/17..   the  above  written  as  queries  instead  (.. can also be
-                          replaced with -)
-       date:..12/1
-       date:thismonth..
-       date:thismonth
-
-   Report intervals
-       A report interval can be specified so that commands like register, bal-
-       ance and activity become multi-period, showing each subperiod as a sep-
-       arate row or column.
-
-       The following "standard" report intervals can be enabled by using their
-       corresponding flag:
-
-       -D/--daily, -W/--weekly, -M/--monthly, -Q/--quarterly, -Y/--yearly.
-
-       These standard intervals always start on natural  interval  boundaries:
-       eg  --weekly  starts  on  mondays, --monthly starts on the first of the
-       month, --yearly always starts on January 1st, etc.
-
-       Certain more complex intervals, and more flexible boundary  dates,  can
-       be  specified  by  -p/--period.   These are described in period expres-
-       sions, below.
-
-       Report intervals can only be specified by the flags above, and  not  by
-       query arguments, currently.
-
-       Report  intervals  have another effect: multi-period reports are always
-       expanded to fill a whole number of subperiods.  So if you use a  report
-       interval  (other  than  --daily), and you have specified a start or end
-       date, you may notice those  dates  being  overridden  (ie,  the  report
-       starts  earlier than your requested start date, or ends later than your
-       requested end date).  This is done to ensure "full" first and last sub-
-       periods, so that all subperiods' numbers are comparable.
-
-   Period expressions
-       The  -p/--period  option accepts period expressions, a shorthand way of
-       expressing a start date, end date, and/or report interval all at  once.
-
-       Here's  a basic period expression specifying the first quarter of 2009.
-       Note, hledger always treats start dates as inclusive and end  dates  as
-       exclusive:
-
-       -p "from 2009/1/1 to 2009/4/1"
-
-       Keywords  like  "from" and "to" are optional, and so are the spaces, as
-       long as you don't run two dates together.  "to" can also be written  as
-       ".." or "-".  These are equivalent to the above:
-
-
-       -p "2009/1/1 2009/4/1"
-       -p2009/1/1to2009/4/1
-       -p2009/1/1..2009/4/1
-
-       Dates  are  smart  dates, so if the current year is 2009, the above can
-       also be written as:
-
-
-       -p "1/1 4/1"
-
-       -p "january-apr"
-       -p "this year to 4/1"
-
-       If you specify only one date, the missing start or end date will be the
-       earliest or latest transaction in your journal:
-
-
-       -p "from 2009/1/1"   everything  after  january
-                            1, 2009
-       -p "from 2009/1"     the same
-       -p "from 2009"       the same
-       -p "to 2009"         everything before  january
-                            1, 2009
-
-       A  single  date  with  no "from" or "to" defines both the start and end
-       date like so:
-
-
-       -p "2009"       the year 2009;  equivalent
-                       to "2009/1/1 to 2010/1/1"
-       -p "2009/1"     the  month of jan; equiva-
-                       lent   to   "2009/1/1   to
-                       2009/2/1"
-       -p "2009/1/1"   just  that day; equivalent
-                       to "2009/1/1 to 2009/1/2"
-
-       Or you can specify a single quarter like so:
-
-
-       -p "2009Q1"   first  quarter  of   2009,
-                     equivalent to "2009/1/1 to
-                     2009/4/1"
-       -p "q4"       fourth quarter of the cur-
-                     rent year
-
-       The  argument  of  -p  can  also  begin  with, or be, a report interval
-       expression.  The basic report intervals  are  daily,  weekly,  monthly,
-       quarterly, or yearly, which have the same effect as the -D,-W,-M,-Q, or
-       -Y flags.  Between report interval and start/end dates  (if  any),  the
-       word in is optional.  Examples:
-
-
-       -p "weekly from 2009/1/1 to 2009/4/1"
-       -p "monthly in 2008"
-       -p "quarterly"
-
-       Note  that  weekly, monthly, quarterly and yearly intervals will always
-       start on the first day on week, month, quarter or year accordingly, and
-       will  end  on  the  last  day of same period, even if associated period
-       expression specifies different explicit start and end date.
-
-       For example:
-
-
-       -p "weekly from  2009/1/1   starts on 2008/12/29, closest preceding Mon-
-       to 2009/4/1"                day
-       -p      "monthly       in   starts on 2018/11/01
-       2008/11/25"
-       -p     "quarterly    from   starts  on  2009/04/01,  ends on 2009/06/30,
-       2009-05-05 to 2009-06-01"   which are first and last days of Q2 2009
-       -p      "yearly      from   starts on 2009/01/01, first day of 2009
-       2009-12-29"
-
-       The  following  more  complex  report  intervals  are  also  supported:
-       biweekly, fortnightly,  bimonthly,  every  day|week|month|quarter|year,
-       every N days|weeks|months|quarters|years.
-
-       All  of  these  will start on the first day of the requested period and
-       end on the last one, as described above.
-
-       Examples:
-
-
-       -p "bimonthly from 2008"    periods will have boundaries on  2008/01/01,
-                                   2008/03/01, ...
-       -p "every 2 weeks"          starts on closest preceding Monday
-       -p  "every  5  month from   periods will have boundaries on  2009/03/01,
-       2009/03"                    2009/08/01, ...
-
-       If  you want intervals that start on arbitrary day of your choosing and
-       span a week, month or year, you need to use any of the following:
-
-       every    Nth     day     of     week,     every     WEEKDAYNAME     (eg
-       mon|tue|wed|thu|fri|sat|sun), every Nth day [of month], every Nth WEEK-
-       DAYNAME [of month], every MM/DD [of year], every  Nth  MMM  [of  year],
-       every MMM Nth [of year].
-
-       Examples:
-
-
-       -p  "every  2nd  day  of   periods will go from Tue to Tue
-       week"
-       -p "every Tue"             same
-       -p "every 15th day"        period boundaries will  be  on  15th  of  each
-                                  month
-       -p "every 2nd Monday"      period  boundaries will be on second Monday of
-                                  each month
-       -p "every 11/05"           yearly periods with boundaries on 5th of Nov
-       -p "every 5th Nov"         same
-       -p "every Nov 5th"         same
-
-       Show historical balances at end of 15th each month (N is exclusive  end
-       date):
-
-       hledger balance -H -p "every 16th day"
-
-       Group  postings  from  start  of wednesday to end of next tuesday (N is
-       start date and exclusive end date):
-
-       hledger register checking -p "every 3rd day of week"
-
-DEPTH
-       With the --depth N option (short form: -N), commands like account, bal-
-       ance  and register will show only the uppermost accounts in the account
-       tree, down to level N.  Use this when you  want  a  summary  with  less
-       detail.   This  flag has the same effect as a depth: query argument (so
-       -2, --depth=2 or depth:2 are equivalent).
-
-QUERIES
-       One of hledger's strengths is being able to quickly report on a precise
-       subset of your data.  Most hledger commands accept optional query argu-
-       ments to restrict their scope.  The syntax is as follows:
-
-       o Zero or more space-separated  query  terms.   These  are  most  often
-         account name substrings:
-
-         utilities food:groceries
-
-       o Terms  with  spaces or other special characters should be enclosed in
-         quotes:
-
-         "personal care"
-
-       o Regular expressions are also supported:
-
-         "^expenses\b" "accounts (payable|receivable)"
-
-       o Add a query type prefix to match other parts of the data:
-
-         date:202012- desc:amazon cur:USD amt:">100" status:
-
-       o Add a not: prefix to negate a term:
-
-         not:cur:USD
-
-   Query types
-       Here are the types of query term available.  Remember these can also be
-       prefixed with not: to convert them into a negative match.
-
-       acct:REGEX, REGEX
-       Match  account names containing this (case insensitive) regular expres-
-       sion.  This is the default query type when there is no prefix, and reg-
-       ular  expression  syntax  is  typically  not needed, so usually we just
-       write an account name substring, like expenses or food.
-
-       amt:N, amt:<N, amt:<=N, amt:>N, amt:>=N
-       Match postings with a single-commodity amount equal to, less  than,  or
-       greater  than N.  (Postings with multi-commodity amounts are not tested
-       and will always match.) The comparison has two modes: if N is  preceded
-       by  a + or - sign (or is 0), the two signed numbers are compared.  Oth-
-       erwise, the absolute magnitudes are compared, ignoring sign.
-
-       code:REGEX
-       Match by transaction code (eg check number).
-
-       cur:REGEX
-       Match  postings  or  transactions  including  any  amounts  whose  cur-
-       rency/commodity  symbol  is  fully  matched  by  REGEX.  (For a partial
-       match, use .*REGEX.*).  Note, to match  special  characters  which  are
-       regex-significant,  you need to escape them with \.  And for characters
-       which are significant to your shell you may  need  one  more  level  of
-       escaping.  So eg to match the dollar sign:
-       hledger print cur:\\$.
-
-       desc:REGEX
-       Match transaction descriptions.
-
-       date:PERIODEXPR
-       Match  dates  (or  with  the  --date2 flag, secondary dates) within the
-       specified period.  PERIODEXPR is a period  expression  with  no  report
-       interval.  Examples:
-       date:2016, date:thismonth, date:2/1-2/15, date:2021-07-27..nextquarter.
-
-       date2:PERIODEXPR
-       Match secondary dates within the specified period (independent  of  the
-       --date2 flag).
-
-       depth:N
-       Match  (or  display,  depending  on  command) accounts at or above this
-       depth.
-
-       note:REGEX
-       Match transaction notes (the part of the description right of |, or the
-       whole description if there's no |).
-
-       payee:REGEX
-       Match  transaction  payee/payer names (the part of the description left
-       of |, or the whole description if there's no |).
-
-       real:, real:0
-       Match real or virtual postings respectively.
-
-       status:, status:!, status:*
-       Match unmarked, pending, or cleared transactions respectively.
-
-       tag:REGEX[=REGEX]
-       Match by tag name, and optionally also by tag value.  (To match only by
-       value,  use  tag:.=REGEX.)  Note  that  postings also inherit tags from
-       their transaction, and transactions also acquire tags from their  post-
-       ings, when querying.
-
-       (inacct:ACCTNAME
-       A  special  query  term  used  automatically in hledger-web only: tells
-       hledger-web to show the transaction register for an account.)
-
-   Combining query terms
-       Most commands select things which match:
-
-       o any of the description terms AND
-
-       o any of the account terms AND
-
-       o any of the status terms AND
-
-       o all the other terms.
-
-       while the print command shows transactions which:
-
-       o match any of the description terms AND
-
-       o have any postings matching any of the positive account terms AND
-
-       o have no postings matching any of the negative account terms AND
-
-       o match all the other terms.
-
-       You can do more powerful queries (such as AND-ing two  like  terms)  by
-       running  a  first query with print, and piping the result into a second
-       hledger command.  Eg: how much of food expenses was paid with cash ?
-
-              $ hledger print assets:cash | hledger f- -I balance expenses:food
-
-       If you are interested in full  boolean  expressions  for  queries,  see
-       #203.
-
-   Queries and command options
-       Some  queries can also be expressed as command-line options: depth:2 is
-       equivalent to --depth 2, date:2020 is equivalent to -p 2020, etc.  When
-       you  mix  command  options and query arguments, generally the resulting
-       query is their intersection.
-
-   Queries and account aliases
-       When account names are rewritten with  --alias  or  alias,  acct:  will
-       match either the old or the new account name.
-
-   Queries and valuation
-       When  amounts  are  converted  to  other  commodities  in cost or value
-       reports, cur: and amt: match the  old  commodity  symbol  and  the  old
-       amount  quantity, not the new ones (except in hledger 1.22.0 where it's
-       reversed, see #1625).
-
-   Querying with account aliases
-       When account names are rewritten with --alias or alias, note that acct:
-       will match either the old or the new account name.
-
-   Querying with cost or value
-       When  amounts  are  converted  to  other  commodities  in cost or value
-       reports, note that cur: matches the new commodity symbol, and  not  the
-       old one, and amt: matches the new quantity, and not the old one.  Note:
-       this changed in hledger 1.22, previously it was the  reverse,  see  the
-       discussion at #1625.
-
-COSTING
-       The  -B/--cost  flag  converts  amounts to their cost or sale amount at
-       transaction time, if they have a transaction price specified.  If  this
-       flag  is supplied, hledger will perform cost conversion first, and will
-       apply any market price valuations (if requested) afterwards.
-
-VALUATION
-       Instead of reporting amounts in their original commodity,  hledger  can
-       convert them to cost/sale amount (using the conversion rate recorded in
-       the transaction), and/or to market value (using some market price on  a
-       certain  date).   This  is  controlled  by the --value=TYPE[,COMMODITY]
-       option, which will be described below.  We also provide the simpler  -V
-       and -X COMMODITY options, and often one of these is all you need:
-
-   -V: Value
-       The  -V/--market flag converts amounts to market value in their default
-       valuation commodity, using the market prices in effect on the valuation
-       date(s), if any.  More on these in a minute.
-
-   -X: Value in specified commodity
-       The -X/--exchange=COMM option is like -V, except you tell it which cur-
-       rency you want to convert to, and it tries  to  convert  everything  to
-       that.
-
-   Valuation date
-       Since  market  prices  can change from day to day, market value reports
-       have a valuation date (or more than one), which determines which market
-       prices will be used.
-
-       For single period reports, if an explicit report end date is specified,
-       that will be used as the valuation date; otherwise the  valuation  date
-       is the journal's end date.
-
-       For  multiperiod  reports, each column/period is valued on the last day
-       of the period, by default.
-
-   Market prices
-       To convert a commodity A to its market value in  another  commodity  B,
-       hledger  looks  for a suitable market price (exchange rate) as follows,
-       in this order of preference :
-
-       1. A declared market price or inferred market price: A's latest  market
-          price in B on or before the valuation date as declared by a P direc-
-          tive, or (with the --infer-market-price flag) inferred from transac-
-          tion prices.
-
-       2. A reverse market price: the inverse of a declared or inferred market
-          price from B to A.
-
-       3. A forward chain of market prices: a synthetic price formed  by  com-
-          bining the shortest chain of "forward" (only 1 above) market prices,
-          leading from A to B.
-
-       4. Any chain of market prices: a chain of any market prices,  including
-          both  forward  and reverse prices (1 and 2 above), leading from A to
-          B.
-
-       There is a limit to the  length  of  these  price  chains;  if  hledger
-       reaches  that length without finding a complete chain or exhausting all
-       possibilities, it will give up (with a "gave  up"  message  visible  in
-       --debug=2 output).  That limit is currently 1000.
-
-       Amounts  for  which no suitable market price can be found, are not con-
-       verted.
-
-   --infer-market-price: market prices from transactions
-       Normally, market value in hledger is fully controlled by, and requires,
-       P directives in your journal.  Since adding and updating those can be a
-       chore, and since transactions usually take place  at  close  to  market
-       value, why not use the recorded transaction prices as additional market
-       prices (as Ledger does) ?  We could produce value reports without need-
-       ing P directives at all.
-
-       Adding the --infer-market-price flag to -V, -X or --value enables this.
-       So for example, hledger bs  -V  --infer-market-price  will  get  market
-       prices  both  from  P  directives  and from transactions.  (And if both
-       occur on the same day, the P directive takes precedence).
-
-       There is a downside: value reports can sometimes be affected in confus-
-       ing/undesired  ways  by  your journal entries.  If this happens to you,
-       read all of this Valuation section carefully, and try adding --debug or
-       --debug=2 to troubleshoot.
-
-       --infer-market-price can infer market prices from:
-
-       o multicommodity transactions with explicit prices (@/@@)
-
-       o multicommodity  transactions with implicit prices (no @, two commodi-
-         ties, unbalanced).  (With  these,  the  order  of  postings  matters.
-         hledger print -x can be useful for troubleshooting.)
-
-       o but  not,  currently, from "more correct" multicommodity transactions
-         (no @, multiple commodities, balanced).
-
-   Valuation commodity
-       When you specify a valuation commodity (-X COMM or --value TYPE,COMM):
-       hledger will convert all amounts to COMM, wherever it can find a  suit-
-       able market price (including by reversing or chaining prices).
-
-       When  you  leave  the  valuation  commodity  unspecified (-V or --value
-       TYPE):
-       For each commodity A, hledger picks a default  valuation  commodity  as
-       follows, in this order of preference:
-
-       1. The price commodity from the latest P-declared market price for A on
-          or before valuation date.
-
-       2. The price commodity from the latest P-declared market price for A on
-          any  date.   (Allows  conversion  to proceed when there are inferred
-          prices before the valuation date.)
-
-       3. If there are no P directives at all (any commodity or date) and  the
-          --infer-market-price flag is used: the price commodity from the lat-
-          est transaction-inferred price for A on or before valuation date.
-
-       This means:
-
-       o If you have P directives, they determine which  commodities  -V  will
-         convert, and to what.
-
-       o If  you  have no P directives, and use the --infer-market-price flag,
-         transaction prices determine it.
-
-       Amounts for which no valuation commodity can  be  found  are  not  con-
-       verted.
-
-   Simple valuation examples
-       Here are some quick examples of -V:
-
-              ; one euro is worth this many dollars from nov 1
-              P 2016/11/01 EUR $1.10
-
-              ; purchase some euros on nov 3
-              2016/11/3
-                  assets:euros        EUR100
-                  assets:checking
-
-              ; the euro is worth fewer dollars by dec 21
-              P 2016/12/21 EUR $1.03
-
-       How many euros do I have ?
-
-              $ hledger -f t.j bal -N euros
-                              EUR100  assets:euros
-
-       What are they worth at end of nov 3 ?
-
-              $ hledger -f t.j bal -N euros -V -e 2016/11/4
-                           $110.00  assets:euros
-
-       What  are they worth after 2016/12/21 ?  (no report end date specified,
-       defaults to today)
-
-              $ hledger -f t.j bal -N euros -V
-                           $103.00  assets:euros
-
-   --value: Flexible valuation
-       -V and -X are special cases of the more general --value option:
-
-               --value=TYPE[,COMM]  TYPE is then, end, now or YYYY-MM-DD.
-                                    COMM is an optional commodity symbol.
-                                    Shows amounts converted to:
-                                    - default valuation commodity (or COMM) using market prices at posting dates
-                                    - default valuation commodity (or COMM) using market prices at period end(s)
-                                    - default valuation commodity (or COMM) using current market prices
-                                    - default valuation commodity (or COMM) using market prices at some date
-
-       The TYPE part selects cost or value and valuation date:
-
-       --value=then
-              Convert amounts to their value in the default valuation  commod-
-              ity, using market prices on each posting's date.
-
-       --value=end
-              Convert  amounts to their value in the default valuation commod-
-              ity, using market prices on the last day of  the  report  period
-              (or  if  unspecified, the journal's end date); or in multiperiod
-              reports, market prices on the last day of each subperiod.
-
-       --value=now
-              Convert amounts to their value in the default valuation  commod-
-              ity  using  current  market  prices (as of when report is gener-
-              ated).
-
-       --value=YYYY-MM-DD
-              Convert amounts to their value in the default valuation  commod-
-              ity using market prices on this date.
-
-       To select a different valuation commodity, add the optional ,COMM part:
-       a comma, then the  target  commodity's  symbol.   Eg:  --value=now,EUR.
-       hledger will do its best to convert amounts to this commodity, deducing
-       market prices as described above.

-
-       You  may  need  to  explicitly  set  a  commodity's display style, when
-       reverse prices are used.  Eg this output might be surprising:
-
-              P 2000-01-01 A 2B
-
-              2000-01-01
-                a  1B
-                b
-
-              $ hledger print -x -X A
-              2000-01-01
-                  a               0
-                  b               0
-
-       Explanation: because there's no amount or commodity directive  specify-
-       ing  a display style for A, 0.5A gets the default style, which shows no
-       decimal digits.  Because the displayed amount looks like zero, the com-
-       modity  symbol  and minus sign are not displayed either.  Adding a com-
-       modity directive sets a more useful display style for A:
-
-              P 2000-01-01 A 2B
-              commodity 0.00A
-
-              2000-01-01
-                a  1B
-                b
-
-              $ hledger print -X A
-              2000-01-01
-                  a           0.50A
-                  b          -0.50A
-
-   Effect of valuation on reports
-       Here is a reference for how valuation is supposed to affect  each  part
-       of  hledger's  reports  (and  a  glossary).  (It's wide, you'll have to
-       scroll sideways.) It may be useful when troubleshooting.  If  you  find
-       problems,  please  report  them,  ideally  with a reproducible example.

-PIVOTING
-       Normally hledger sums amounts, and organizes them in a hierarchy, based
-       on account name.  The --pivot FIELD option causes it to sum  and  orga-
-       nize  hierarchy  based on the value of some other field instead.  FIELD
-       can be: code, description, payee, note, or the full name (case insensi-
-       tive) of any tag.  As with account names, values containing colon:sepa-
-       rated:parts will be displayed hierarchically in reports.
-
-       --pivot is a general option affecting all reports;  you  can  think  of
-       hledger transforming the journal before any other processing, replacing
-       every posting's account name with the value of the specified  field  on
-       that posting, inheriting it from the transaction or using a blank value
-       if it's not present.
-
-       An example:
-
-              2016/02/16 Member Fee Payment
-                  assets:bank account                    2 EUR
-                  income:member fees                    -2 EUR  ; member: John Doe
-
-       Normal balance report showing account names:
-
-              $ hledger balance
-                             2 EUR  assets:bank account
-                            -2 EUR  income:member fees
-              --------------------
-                                 0
-
-       Pivoted balance report, using member: tag values instead:
-
-              $ hledger balance --pivot member
-                             2 EUR
-                            -2 EUR  John Doe
-              --------------------
-                                 0
-
-       One way to show only amounts with  a  member:  value  (using  a  query,
-       described below):
-
-              $ hledger balance --pivot member tag:member=.
-                            -2 EUR  John Doe
-              --------------------
-                            -2 EUR
-
-       Another  way  (the  acct:  query  matches  against the pivoted "account
-       name"):
-
-              $ hledger balance --pivot member acct:.
-                            -2 EUR  John Doe
-              --------------------
-                            -2 EUR

-OUTPUT
-   Output destination
-       hledger commands send their output to the terminal by default.  You can
-       of course redirect this, eg into a file, using standard shell syntax:
-
-              $ hledger print > foo.txt
-
-       Some  commands (print, register, stats, the balance commands) also pro-
-       vide the -o/--output-file option, which does  the  same  thing  without
-       needing the shell.  Eg:
-
-              $ hledger print -o foo.txt
-              $ hledger print -o -        # write to stdout (the default)
-
-       hledger   can   optionally   produce  debug  output  (if  enabled  with
-       --debug=N); this goes to stderr, and is not  affected  by  -o/--output-
-       file.   If you need to capture it, use shell redirects, eg: hledger bal
-       --debug=3 >file 2>&1.
-
-   Output format
-       Some commands (print, register, the balance commands) offer a choice of
-       output format.  In addition to the usual plain text format (txt), there
-       are CSV (csv), HTML (html), JSON (json) and SQL (sql).   This  is  con-
-       trolled by the -O/--output-format option:
-
-              $ hledger print -O csv
-
-       or, by a file extension specified with -o/--output-file:
-
-              $ hledger balancesheet -o foo.html   # write HTML to foo.html
-
-       The -O option can be used to override the file extension if needed:
-
-              $ hledger balancesheet -o foo.txt -O html   # write HTML to foo.txt
-
-       Some notes about JSON output:
-
-       o This  feature  is  marked  experimental,  and  not yet much used; you
-         should expect our JSON to evolve.  Real-world feedback is welcome.
-
-       o Our JSON is rather large and verbose, as it is quite a faithful  rep-
-         resentation  of  hledger's  internal  data  types.  To understand the
-         JSON,  read  the  Haskell  type  definitions,  which  are  mostly  in
-         https://github.com/simonmichael/hledger/blob/master/hledger-
-         lib/Hledger/Data/Types.hs.
-
-       o hledger represents quantities as Decimal values  storing  up  to  255
-         significant  digits,  eg  for  repeating  decimals.  Such numbers can
-         arise in practice (from automatically-calculated transaction prices),
-         and  would break most JSON consumers.  So in JSON, we show quantities
-         as simple Numbers with at most 10 decimal places.  We don't limit the
-         number  of  integer  digits, but that part is under your control.  We
-         hope this approach will not cause problems in practice; if  you  find
-         otherwise, please let us know.  (Cf #1195)
-
-       Notes about SQL output:
-
-       o SQL  output is also marked experimental, and much like JSON could use
-         real-world feedback.
-
-       o SQL output is expected to work with sqlite, MySQL and PostgreSQL
-
-       o SQL output is structured with the expectations that  statements  will
-         be  executed  in the empty database.  If you already have tables cre-
-         ated via SQL output of hledger, you would  probably  want  to  either
-         clear tables of existing data (via delete or truncate SQL statements)
-         or drop tables completely as otherwise your postings will be duped.

-
-       Next, the detailed command docs, in alphabetical order.
-
-   accounts
-       accounts
-       Show account names.
-
-       This command lists account names, either declared with  account  direc-
-       tives  (--declared),  posted  to (--used), or both (the default).  With
-       query arguments, only matched account names and  account  names  refer-
-       enced  by matched postings are shown.  It shows a flat list by default.
-       With --tree, it uses indentation to show  the  account  hierarchy.   In
-       flat  mode you can add --drop N to omit the first few account name com-
-       ponents.  Account names can be depth-clipped with depth:N or --depth  N
-       or -N.
-
-       Examples:
-
-              $ hledger accounts
-              assets:bank:checking
-              assets:bank:saving

-              liabilities:debts
-
-   activity
-       activity
-       Show an ascii barchart of posting counts per interval.
-
-       The  activity  command  displays an ascii histogram showing transaction
-       counts by day, week, month or other reporting interval (by day  is  the
-       default).  With query arguments, it counts only matched transactions.
-
-       Examples:
-
-              $ hledger activity --quarterly
-              2008-01-01 **

-       add
-       Prompt  for  transactions  and  add them to the journal.  Any arguments
-       will be used as default inputs for the first N prompts.
-
-       Many hledger users edit their journals directly with a text editor,  or
-       generate  them from CSV.  For more interactive data entry, there is the
-       add command, which prompts interactively on the console for new  trans-
-       actions, and appends them to the journal file (if there are multiple -f
-       FILE options, the first file is used.) Existing  transactions  are  not
-       changed.   This  is the only hledger command that writes to the journal
-       file.
-
-       To use it, just run hledger add and follow the prompts.  You can add as
-       many  transactions as you like; when you are finished, enter . or press
-       control-d or control-c to exit.
-
-       Features:
-
-       o add tries to provide useful defaults,  using  the  most  similar  (by
-         description)  recent transaction (filtered by the query, if any) as a
-         template.
-
-       o You can also set the initial defaults with command line arguments.
-
-       o Readline-style edit keys can be used during data entry.
-
-       o The tab key will auto-complete whenever possible - accounts, descrip-
-         tions,  dates  (yesterday,  today,  tomorrow).   If the input area is
-         empty, it will insert the default value.
-
-       o If the journal defines a default commodity, it will be added  to  any
-         bare numbers entered.
-
-       o A parenthesised transaction code may be entered following a date.
-
-       o Comments and tags may be entered following a description or amount.
-
-       o If you make a mistake, enter < at any prompt to go one step backward.
-
-       o Input prompts are displayed in a different colour when  the  terminal
-         supports it.
-
-       Example (see the tutorial for a detailed explanation):
-
-              $ hledger add
-              Adding transactions to journal file /src/hledger/examples/sample.journal
-              Any command line arguments will be used as defaults.
-              Use tab key to complete, readline keys to edit, enter to accept defaults.
-              An optional (CODE) may follow transaction dates.
-              An optional ; COMMENT may follow descriptions or amounts.
-              If you make a mistake, enter < at any prompt to go one step backward.
-              To end a transaction, enter . when prompted.
-              To quit, enter . at a date prompt or press control-d or control-c.
-              Date [2015/05/22]:

-
-       On  Microsoft  Windows,  the add command makes sure that no part of the
-       file path ends with a period, as that would cause problems (#1056).
-
-   aregister
-       aregister, areg
-
-       Show the transactions and running historical  balance  in  an  account,
-       with each line item representing one transaction.
-
-       aregister shows the transactions affecting a particular account and its
-       subaccounts, with each line item representing a whole transaction -  as
-       in  bank statements, hledger-ui, hledger-web and other accounting apps.
-
-       Note this is unlike the register command, which shows individual  post-
-       ings and does not always show a single account or a historical balance.
-
-       A reminder, "historical" balances include any balance from transactions
-       before the report start date, so (if opening balances are recorded cor-
-       rectly) aregister will show the real-world balances of an  account,  as
-       you would see in a bank statement.
-
-       As  a  quick  rule  of  thumb, use aregister for reconciling real-world
-       asset/liability accounts  and  register  for  reviewing  detailed  rev-
-       enues/expenses.
-
-       aregister  shows  the  register  for  just  one account (and its subac-
-       counts).  This account must be specified as the  first  argument.   You
-       can  write  either the full account name, or a case-insensitive regular
-       expression which will select the alphabetically first matched  account.
-       (Eg  if  you have assets:aaa:checking and assets:bbb:checking accounts,
-       hledger areg checking would select assets:aaa:checking.)
-
-       Any additional arguments form a query which will  filter  the  transac-
-       tions shown.
-
-       Each aregister line item shows:
-
-       o the  transaction's date (or the relevant posting's date if different,
-         see below)
-
-       o the names of all the other account(s) involved  in  this  transaction
-         (probably abbreviated)
-
-       o the total change to this account's balance from this transaction
-
-       o the account's historical running balance after this transaction.
-
-       Transactions  making a net change of zero are not shown by default; add
-       the -E/--empty flag to show them.
-
-       aregister ignores a depth limit, so its final total will always match a
-       balance report with similar arguments.
-
-       This  command  also  supports  the output destination and output format
-       options The output formats supported are txt, csv, and json.
-
-   aregister and custom posting dates
-       Transactions whose date is outside  the  report  period  can  still  be
-       shown,  if  they have a posting to this account dated inside the report
-       period.  (And in this case it's the posting date that is  shown.)  This
-       ensures that aregister can show an accurate historical running balance,
-       matching the one shown by register -H with the same arguments.
-
-       To filter strictly by transaction date  instead,  add  the  --txn-dates
-       flag.   If  you  use  this  flag  and some of your postings have custom
-       dates, it's probably best to assume the running balance is wrong.
-
-       Examples:
-
-       Show all transactions and  historical  running  balance  in  the  first
-       account whose name contains "checking":
-
-              $ hledger areg checking
-
-       Show  transactions and historical running balance in all asset accounts
-       during july:
-
-              $ hledger areg assets date:jul
-
-   balance
-       balance, bal
-       Show accounts and their balances.
-
-       balance is one of hledger's oldest and  most  versatile  commands,  for
-       listing  account  balances,  balance changes, values, value changes and
-       more, during one time period or many.  Generally it shows a table, with
-       rows representing accounts, and columns representing periods.
-
-       Note  there  are some higher-level variants of the balance command with
-       convenient defaults, which can be simpler to  use:  balancesheet,  bal-
-       ancesheetequity, cashflow and incomestatement.  When you need more con-
-       trol, then use balance.
-
-   balance features
-       Here's a quick overview of the balance command's features, followed  by
-       more  detailed  descriptions and examples.  Many of these work with the
-       higher-level commands as well.
-
-       balance can show..
-
-       o accounts as a list (-l) or a tree (-t)
-
-       o optionally depth-limited (-[1-9])
-
-       o sorted by declaration order and name, or by amount
-
-       ..and their..
-
-       o balance changes (the default)
-
-       o or actual and planned balance changes (--budget)
-
-       o or value of balance changes (-V)
-
-       o or change of balance values (--valuechange)
-
-       ..in..
-
-       o one time period (the whole journal period by default)
-
-       o or multiple periods (-D, -W, -M, -Q, -Y, -p INTERVAL)
-
-       ..either..
-
-       o per period (the default)
-
-       o or accumulated since report start date (--cumulative)
-
-       o or accumulated since account creation (--historical/-H)
-
-       ..possibly converted to..
-
-       o cost (--value=cost[,COMM]/--cost/-B)
-
-       o or market value, as of transaction dates (--value=then[,COMM])
-
-       o or at period ends (--value=end[,COMM])
-
-       o or now (--value=now)
-
-       o or at some other date (--value=YYYY-MM-DD)
-
-       ..with..
-
-       o totals  (-T),  averages  (-A),  percentages   (-%),   inverted   sign
-         (--invert)
-
-       o rows and columns swapped (--transpose)
-
-       o another field used as account name (--pivot)
-
-       o custom-formatted line items (single-period reports only) (--format)
-
-       This command supports the output destination and output format options,
-       with output formats txt, csv, json, and  (multi-period  reports  only:)
-       html.   In txt output in a colour-supporting terminal, negative amounts
-       are shown in red.
-
-   Simple balance report
-       With no arguments, balance shows a  list  of  all  accounts  and  their
-       change  of  balance  - ie, the sum of posting amounts, both inflows and
-       outflows - during the entire period of  the  journal.   For  real-world
-       accounts,  this  should  also match their end balance at the end of the
-       journal period (more on this below).
-
-       Accounts are sorted by declaration order if any,  and  then  alphabeti-
-       cally by account name.  For instance, using examples/sample.journal:
-
-              $ hledger bal
-                                $1  assets:bank:saving
-                               $-2  assets:cash
-                                $1  expenses:food
-                                $1  expenses:supplies
-                               $-1  income:gifts
-                               $-1  income:salary
-                                $1  liabilities:debts
-              --------------------
-                                 0
-
-       Accounts with a zero balance (and no non-zero subaccounts, in tree mode
-       - see below) are hidden  by  default.   Use  -E/--empty  to  show  them
-       (revealing assets:bank:checking here):
-
-              $ hledger -f examples/sample.journal  bal  -E
-                                 0  assets:bank:checking
-                                $1  assets:bank:saving
-                               $-2  assets:cash
-                                $1  expenses:food
-                                $1  expenses:supplies
-                               $-1  income:gifts
-                               $-1  income:salary
-                                $1  liabilities:debts
-              --------------------
-                                 0
-
-       The  total  of  the amounts displayed is shown as the last line, unless
-       -N/--no-total is used.
-
-   Filtered balance report
-       You can show fewer accounts,  a  different  time  period,  totals  from
-       cleared transactions only, etc.  by using query arguments or options to
-       limit the postings being matched.  Eg:
-
-              $ hledger bal --cleared assets date:200806
-                               $-2  assets:cash
-              --------------------
-                               $-2
-
-   List or tree mode
-       By default, or with -l/--flat, accounts are shown as a flat  list  with
-       their full names visible, as in the examples above.
-
-       With  -t/--tree,  the  account  hierarchy  is  shown, with subaccounts'
-       "leaf" names indented below their parent:
-
-              $ hledger balance
-                               $-1  assets
-                                $1    bank:saving
-                               $-2    cash
-                                $2  expenses
-                                $1    food
-                                $1    supplies
-                               $-2  income
-                               $-1    gifts
-                               $-1    salary
-                                $1  liabilities:debts
-              --------------------
-                                 0
-
-       Notes:
-
-       o "Boring" accounts are combined with their subaccount for more compact
-         output,  unless  --no-elide is used.  Boring accounts have no balance
-         of their own and just one subaccount (eg assets:bank and  liabilities
-         above).
-
-       o All  balances  shown  are "inclusive", ie including the balances from
-         all subaccounts.  Note this means  some  repetition  in  the  output,
-         which requires explanation when sharing reports with non-plaintextac-
-         counting-users.  A tree mode report's final total is the sum  of  the
-         top-level balances shown, not of all the balances shown.
-
-       o Each  group of sibling accounts (ie, under a common parent) is sorted
-         separately.
-
-   Depth limiting
-       With a depth:N query, or --depth N option, or just -N, balance  reports
-       will  show accounts only to the specified depth, hiding the deeper sub-
-       accounts.  Account balances at the depth limit always include the  bal-
-       ances  from  any  hidden  subaccounts (even in list mode).  This can be
-       useful for getting an overview.  Eg, limiting to depth 1:
-
-              $ hledger balance -N -1
-                               $-1  assets
-                                $2  expenses
-                               $-2  income
-                                $1  liabilities
-
-       You can also hide top-level account name parts, using --drop  N.   This
-       can be useful for hiding repetitive top-level account names:
-
-              $ hledger bal expenses --drop 1
-                                $1  food
-                                $1  supplies
-              --------------------
-                                $2
-
-
-   Multi-period balance report
-       With   a   report   interval   (set  by  the  -D/--daily,  -W/--weekly,
-       -M/--monthly, -Q/--quarterly, -Y/--yearly, or -p/--period  flag),  bal-
-       ance  shows a tabular report, with columns representing successive time
-       periods (and a title):
-
-              $ hledger balance --quarterly income expenses -E
-              Balance changes in 2008:
-
-                                 ||  2008q1  2008q2  2008q3  2008q4
-              ===================++=================================
-               expenses:food     ||       0      $1       0       0
-               expenses:supplies ||       0      $1       0       0
-               income:gifts      ||       0     $-1       0       0
-               income:salary     ||     $-1       0       0       0
-              -------------------++---------------------------------
-                                 ||     $-1      $1       0       0
-
-       Notes:
-
-       o The report's start/end dates will be expanded, if necessary, to fully
-         encompass the displayed subperiods (so that the first and last subpe-
-         riods have the same duration as the others).
-
-       o Leading and trailing periods (columns) containing all zeroes are  not
-         shown, unless -E/--empty is used.
-
-       o Accounts   (rows)   containing  all  zeroes  are  not  shown,  unless
-         -E/--empty is used.
-
-       o Amounts with many commodities are shown in abbreviated  form,  unless
-         --no-elide is used.  (experimental)
-
-       o Average  and/or  total columns can be added with the -A/--average and
-         -T/--row-total flags.
-
-       o The --transpose flag can be used to exchange rows and columns.
-
-       o The --pivot FIELD option causes a different transaction field  to  be
-         used as "account name".  See PIVOTING.
-
-       Multi-period reports with many periods can be too wide for easy viewing
-       in the terminal.  Here are some ways to handle that:
-
-       o Hide the totals row with -N/--no-total
-
-       o Convert to a single currency with -V
-
-       o Maximize the terminal window
-
-       o Reduce the terminal's font size
-
-       o View with a pager like less, eg: hledger bal -D  --color=yes  |  less
-         -RS
-
-       o Output  as  CSV and use a CSV viewer like visidata (hledger bal -D -O
-         csv | vd -f csv), Emacs' csv-mode  (M-x  csv-mode,  C-c  C-a),  or  a
-         spreadsheet (hledger bal -D -o a.csv && open a.csv)
-
-       o Output  as  HTML and view with a browser: hledger bal -D -o a.html &&
-         open a.html
-
-   Sorting by amount
-       With -S/--sort-amount, accounts with the largest (most  positive)  bal-
-       ances  are  shown first.  Eg: hledger bal expenses -MAS shows your big-
-       gest averaged monthly expenses first.
-
-       Revenues and liability balances are typically negative, however, so  -S
-       shows  these  in  reverse  order.   To  work  around  this, you can add
-       --invert to flip the signs.  (Or, use one of the higher-level  reports,
-       which  flip the sign automatically.  Eg: hledger incomestatement -MAS).
-
-
-   Percentages
-       With -%/--percent, balance reports show each account's value  expressed
-       as a percentage of the (column) total:
-
-              $ hledger bal expenses -Q -%
-              Balance changes in 2008:
-
-                                 || 2008Q1   2008Q2  2008Q3  2008Q4
-              ===================++=================================
-               expenses:food     ||      0   50.0 %       0       0
-               expenses:supplies ||      0   50.0 %       0       0
-              -------------------++---------------------------------

-
-       Note it is not useful to calculate percentages if the amounts in a col-
-       umn have mixed signs.  In this case, make a separate  report  for  each
-       sign, eg:
-
-              $ hledger bal -% amt:`>0`
-              $ hledger bal -% amt:`<0`
-
-       Similarly,  if  the amounts in a column have mixed commodities, convert
-       them to one commodity with -B, -V, -X or --value, or  make  a  separate
-       report for each commodity:
-
-              $ hledger bal -% cur:\\$
-              $ hledger bal -% cur:EUR
-
-   Balance change, end balance
-       It's  important to be clear on the meaning of the numbers shown in bal-
-       ance reports.  Here is some terminology we use:
-
-       A balance change is the net  amount  added  to,  or  removed  from,  an
-       account during some period.
-
-       An  end balance is the amount accumulated in an account as of some date
-       (and some time, but hledger doesn't store that; assume end  of  day  in
-       your timezone).  It is the sum of previous balance changes.
-
-       We  call it a historical end balance if it includes all balance changes
-       since the account was created.  For a real world account, this means it
-       will  match  the  "historical record", eg the balances reported in your
-       bank statements or bank web UI.  (If they are correct!)
-
-       In general, balance changes are what you want  to  see  when  reviewing
-       revenues and expenses, and historical end balances are what you want to
-       see when reviewing or reconciling asset, liability and equity accounts.
-
-       balance  shows  balance changes by default.  To see accurate historical
-       end balances:
-
-       1. Initialise account starting  balances  with  an  "opening  balances"
-          transaction  (a  transfer  from  equity  to the account), unless the
-          journal covers the account's full lifetime.
-
-       2. Include all of of the account's prior postings in the report, by not
-          specifying  a  report  start  date,  or by using the -H/--historical
-          flag.  (-H causes report start date to be ignored when summing post-
-          ings.)
-
-   Balance report types
-       For more flexible reporting, there are three important option groups:
-
-       hledger  balance  [CALCULATIONTYPE]  [ACCUMULATIONTYPE] [VALUATIONTYPE]
-       ...
-
-       The first two are the most  important:  calculation  type  selects  the
-       basic  calculation  to  perform for each table cell, while accumulation
-       type says which postings should be included in each cell's calculation.
-       Typically  one  or  both of these are selected by default, so you don't
-       need to write them explicitly.  A valuation type can be  added  if  you
-       want to convert the basic report to value or cost.
-
-       Calculation type:
-       The basic calculation to perform for each table cell.  It is one of:
-
-       o --sum : sum the posting amounts (default)
-
-       o --budget : like --sum but also show a goal amount
-
-       o --valuechange : show the change in period-end historical balance val-
-         ues
-
-       Accumulation type:
-       Which postings should be included in each cell's  calculation.   It  is
-       one of:
-
-       o --change  :  postings  from column start to column end, ie within the
-         cell's period.  Typically used to  see  revenues/expenses.   (default
-         for balance, incomestatement)
-
-       o --cumulative  :  postings from report start to column end, eg to show
-         changes accumulated since the report's start date.  Rarely used.
-
-       o --historical/-H : postings from journal start to column end,  ie  all
-         postings from account creation to the end of the cell's period.  Typ-
-         ically  used  to  see  historical  end  balances  of  assets/liabili-
-         ties/equity.   (default  for  balancesheet, balancesheetequity, cash-
-         flow)
-
-       Valuation type:
-       Which kind of valuation, valuation date(s) and optionally a target val-
-       uation commodity to use.  It is one of:
-
-       o no valuation, show amounts in their original commodities (default)
-
-       o --value=cost[,COMM] : no valuation, show amounts converted to cost
-
-       o --value=then[,COMM] : show value at transaction dates
-
-       o --value=end[,COMM]  :  show value at period end date(s) (default with
-         --valuechange)
-
-       o --value=now[,COMM] : show value at today's date
-
-       o --value=YYYY-MM-DD[,COMM] : show value at another date
-
-       or one of their aliases: --cost/-B, --market/-V or --exchange/-X.
-
-       Most combinations of these options should produce  reasonable  reports,
-       but  if  you  find any that seem wrong or misleading, let us know.  The
-       following restrictions are applied:
-
-       o --valuechange implies --value=end
-
-       o --valuechange makes --change the default  when  used  with  the  bal-
-         ancesheet/balancesheetequity commands
-
-       o --cumulative or --historical disables --row-total/-T
-
-       For reference, here is what the combinations of accumulation and valua-
-       tion show:
-
-
-       Valua-     no valuation       --value= then       --value= end       --value= YYYY-

-
-   Useful balance reports
-       Some frequently used balance options/reports are:
-
-       o bal -M revenues expenses
-       Show revenues/expenses in each month.  Also available as  the  incomes-
-       tatement command.
-
-       o bal -M -H assets liabilities
-       Show  historical  asset/liability  balances  at  each  month end.  Also
-       available as the balancesheet command.
-
-       o bal -M -H assets liabilities equity
-       Show historical asset/liability/equity  balances  at  each  month  end.
-       Also available as the balancesheetequity command.
-
-       o bal -M assets not:receivable
-       Show  changes  to  liquid  assets in each month.  Also available as the
-       cashflow command.
-
-       Also:
-
-       o bal -M expenses -2 -SA
-       Show monthly expenses summarised to  depth  2  and  sorted  by  average
-       amount.
-
-       o bal -M --budget expenses
-       Show monthly expenses and budget goals.
-
-       o bal -M --valuechange investments
-       Show monthly change in market value of investment assets.
-
-       o bal  investments  --valuechange  -D  date:lastweek  amt:'>1000'  -STA
-         [--invert]
-       Show top gainers [or losers] last week
-
-   Budget report
-       The --budget report type activates extra  columns  showing  any  budget
-       goals  for  each  account  and period.  The budget goals are defined by
-       periodic transactions.  This is very useful for comparing  planned  and
-       actual income, expenses, time usage, etc.
-
-       For  example,  you  can  take  average  monthly  expenses in the common
-       expense categories to construct a minimal monthly budget:
-
-              ;; Budget
-              ~ monthly
-                income  $2000
-                expenses:food    $400
-                expenses:bus     $50
-                expenses:movies  $30
-                assets:bank:checking
-
-              ;; Two months worth of expenses
-              2017-11-01
-                income  $1950
-                expenses:food    $396
-                expenses:bus     $49
-                expenses:movies  $30
-                expenses:supplies  $20
-                assets:bank:checking
-
-              2017-12-01
-                income  $2100
-                expenses:food    $412
-                expenses:bus     $53
-                expenses:gifts   $100
-                assets:bank:checking
-
-       You can now see a monthly budget report:
-
-              $ hledger balance -M --budget

-       This is different from a normal balance report in several ways:
-
-       o Only accounts with budget goals during the report period  are  shown,
-         by default.
-
-       o In  each  column,  in square brackets after the actual amount, budget
-         goal amounts are shown, and the actual/goal percentage.  (Note:  bud-
-         get goals should be in the same commodity as the actual amount.)
-
-       o All  parent accounts are always shown, even in list mode.  Eg assets,
-         assets:bank, and expenses above.
-
-       o Amounts always include all subaccounts, budgeted or unbudgeted,  even
-         in list mode.
-
-       This means that the numbers displayed will not always add up! Eg above,
-       the expenses actual amount includes the  gifts  and  supplies  transac-
-       tions,  but  the  expenses:gifts and expenses:supplies accounts are not
-       shown, as they have no budget amounts declared.
-
-       This can be confusing.  When you need to make things clearer,  use  the
-       -E/--empty  flag,  which  will reveal all accounts including unbudgeted
-       ones, giving the full picture.  Eg:
-
-              $ hledger balance -M --budget --empty

-   Budget report start date
-       This might be a bug, but for now: when making budget  reports,  it's  a
-       good idea to explicitly set the report's start date to the first day of
-       a reporting period, because a periodic rule like  ~  monthly  generates
-       its  transactions  on the 1st of each month, and if your journal has no
-       regular transactions on the 1st, the default report  start  date  could
-       exclude  that  budget  goal, which can be a little surprising.  Eg here
-       the default report period is just the day of 2020-01-15:
-
-              ~ monthly in 2020
-                (expenses:food)  $500
-
-              2020-01-15
-                expenses:food    $400
-                assets:checking
-
-              $ hledger bal expenses --budget

-
-       To avoid this, specify the budget report's  period,  or  at  least  the
-       start  date, with -b/-e/-p/date:, to ensure it includes the budget goal
-       transactions (periodic transactions) that  you  want.   Eg,  adding  -b
-       2020/1/1 to the above:
-
-              $ hledger bal expenses --budget -b 2020/1/1

-   Nested budgets
-       You  can  add budgets to any account in your account hierarchy.  If you
-       have budgets on both parent account and some of its children, then bud-
-       get(s)  of  the  child account(s) would be added to the budget of their
-       parent, much like account balances behave.
-
-       In the most simple case this means that once you add a  budget  to  any
-       account, all its parents would have budget as well.
-
-       To illustrate this, consider the following budget:
-
-              ~ monthly from 2019/01
-                  expenses:personal             $1,000.00
-                  expenses:personal:electronics    $100.00
-                  liabilities
-
-       With  this,  monthly  budget  for electronics is defined to be $100 and
-       budget for personal expenses is an additional $1000,  which  implicitly
-       means that budget for both expenses:personal and expenses is $1100.
-
-       Transactions  in  expenses:personal:electronics  will  be  counted both
-       towards its $100 budget and $1100 of expenses:personal ,  and  transac-
-       tions  in  any  other  subaccount of expenses:personal would be counted
-       towards only towards the budget of expenses:personal.
-
-       For example, let's consider these transactions:
-
-              ~ monthly from 2019/01
-                  expenses:personal             $1,000.00
-                  expenses:personal:electronics    $100.00
-                  liabilities

-                  expenses:personal          $30.00
-                  liabilities
-
-       As you can see, we  have  transactions  in  expenses:personal:electron-
-       ics:upgrades  and  expenses:personal:train  tickets,  and since both of
-       these accounts are without explicitly defined  budget,  these  transac-
-       tions would be counted towards budgets of expenses:personal:electronics
-       and expenses:personal accordingly:

-   Customising single-period balance reports
-       For single-period balance reports displayed in the terminal (only), you
-       can use --format FMT to customise the format and content of each  line.
-       Eg:
-
-              $ hledger balance --format "%20(account) %12(total)"
-                            assets          $-1
-                       bank:saving           $1
-                              cash          $-2
-                          expenses           $2
-                              food           $1
-                          supplies           $1

-                            salary          $-1

-
-       The FMT format string (plus a newline) specifies the formatting applied
-       to each account/balance pair.  It may contain any suitable  text,  with
-       data fields interpolated like so:
-
-       %[MIN][.MAX](FIELDNAME)
-
-       o MIN pads with spaces to at least this width (optional)
-
-       o MAX truncates at this width (optional)
-
-       o FIELDNAME must be enclosed in parentheses, and can be one of:
-
-         o depth_spacer  - a number of spaces equal to the account's depth, or
-           if MIN is specified, MIN * depth spaces.
-
-         o account - the account's name
-
-         o total - the account's balance/posted total, right justified
-
-       Also, FMT can begin with an optional prefix to control  how  multi-com-
-       modity amounts are rendered:
-
-       o %_ - render on multiple lines, bottom-aligned (the default)
-
-       o %^ - render on multiple lines, top-aligned
-
-       o %, - render on one line, comma-separated
-
-       There  are  some  quirks.   Eg in one-line mode, %(depth_spacer) has no
-       effect, instead %(account) has indentation built  in.   Experimentation
-       may be needed to get pleasing results.
-
-       Some example formats:
-
-       o %(total) - the account's total
-
-       o %-20.20(account)  -  the account's name, left justified, padded to 20
-         characters and clipped at 20 characters
-
-       o %,%-50(account)  %25(total) - account name padded to  50  characters,
-         total  padded to 20 characters, with multiple commodities rendered on
-         one line
-
-       o %20(total)  %2(depth_spacer)%-(account) - the default format for  the
-         single-column balance report

-   balancesheet
-       balancesheet, bs
-       This  command  displays a balance sheet, showing historical ending bal-

-   check
-       check
-       Check for various kinds of errors in your data.
-
-       hledger provides a number of built-in  error  checks  to  help  prevent
-       problems  in  your  data.  Some of these are run automatically; or, you
-       can use this check command to run them on demand, with no output and  a
-       zero  exit  code  if all is well.  Specify their names (or a prefix) as
-       argument(s).
-
-       Some examples:
-
-              hledger check      # basic checks
-              hledger check -s   # basic + strict checks
-              hledger check ordereddates payees  # basic + two other checks
-
-       Here are the checks currently available:
-
-   Basic checks
-       These checks are always run automatically, by (almost) all hledger com-
-       mands, including check:
-
-       o parseable - data files are well-formed and can be successfully parsed
-
-       o balancedwithautoconversion - all transactions are balanced, inferring
-         missing  amounts where necessary, and possibly converting commodities
-         using transaction prices or automatically-inferred transaction prices
-
-       o assertions  -  all  balance  assertions  in  the journal are passing.
-         (This check can be disabled with -I/--ignore-assertions.)
-
-   Strict checks
-       These additional checks are run when the -s/--strict (strict mode) flag
-       is  used.   Or,  they  can be run by giving their names as arguments to
-       check:
-
-       o accounts - all account names used by transactions have been declared
-
-       o commodities - all commodity symbols used have been declared
-
-       o balancednoautoconversion - transactions are balanced, possibly  using
-         explicit transaction prices but not inferred ones
-
-   Other checks
-       These  checks  can  be  run  only by giving their names as arguments to
-       check.  They are more  specialised  and  not  desirable  for  everyone,
-       therefore optional:
-
-       o ordereddates - transactions are ordered by date within each file
-
-       o payees - all payees used by transactions have been declared
-
-       o uniqueleafnames - all account leaf names are unique
-
-   Custom checks
-       A  few  more  checks  are are available as separate add-on commands, in
-       https://github.com/simonmichael/hledger/tree/master/bin:
-
-       o hledger-check-tagfiles - all  tag  values  containing  /  (a  forward
-         slash) exist as file paths
-
-       o hledger-check-fancyassertions  -  more complex balance assertions are
-         passing
-
-       You could make similar scripts to perform your own custom checks.  See:
-       Cookbook -> Scripting.
-
-   close
-       close, equity
-       Prints  a  "closing  balances"  transaction  and  an "opening balances"
-       transaction that bring account balances to and from zero, respectively.
-       These can be added to your journal file(s), eg to bring asset/liability
-       balances forward into  a  new  journal  file,  or  to  close  out  rev-
-       enues/expenses to retained earnings at the end of a period.
-
-       You  can  print  just one of these transactions by using the --close or
-       --open flag.  You can customise their descriptions  with  the  --close-
-       desc and --open-desc options.
-
-       One amountless posting to "equity:opening/closing balances" is added to
-       balance the transactions, by default.  You can customise  this  account
-       name  with  --close-acct  and  --open-acct;  if you specify only one of
-       these, it will be used for both.
-
-       With --x/--explicit, the equity posting's amount will be shown.  And if
-       it  involves multiple commodities, a posting for each commodity will be
-       shown, as with the print command.
-
-       With --interleaved, the equity postings are shown next to the  postings
-       they balance, which makes troubleshooting easier.
-
-       By default, transaction prices in the journal are ignored when generat-
-       ing the closing/opening transactions.   With  --show-costs,  this  cost
-       information  is  preserved  (balance -B reports will be unchanged after
-       the transition).  Separate postings are generated for each cost in each
-       commodity.   Note  this can generate very large journal entries, if you
-       have many foreign currency or investment transactions.
-
-   close usage
-       If you split your journal files by time (eg yearly), you will typically
-       run  this command at the end of the year, and save the closing transac-
-       tion as last entry of the old file, and the opening transaction as  the
-       first  entry  of the new file.  This makes the files self contained, so
-       that correct balances are reported no matter which of them are  loaded.
-       Ie,  if you load just one file, the balances are initialised correctly;
-       or if you load several files, the  redundant  closing/opening  transac-
-       tions  cancel  each other out.  (They will show up in print or register
-       reports; you can  exclude  them  with  a  query  like  not:desc:'(open-
-       ing|closing) balances'.)
-
-       If you're running a business, you might also use this command to "close
-       the books" at the end of  an  accounting  period,  transferring  income
-       statement  account  balances  to  retained  earnings.  (You may want to
-       change the equity account name to something like "equity:retained earn-
-       ings".)
-
-       By  default,  the  closing transaction is dated yesterday, the balances
-       are calculated as of end of yesterday, and the opening  transaction  is
-       dated  today.  To close on some other date, use: hledger close -e OPEN-
-       INGDATE.  Eg, to close/open on the 2018/2019  boundary,  use  -e  2019.
-       You can also use -p or date:PERIOD (any starting date is ignored).
-
-       Both   transactions   will   include   balance   assertions   for   the
-       closed/reopened accounts.  You probably shouldn't use status  or  real-
-       ness  filters (like -C or -R or status:) with this command, or the gen-
-       erated balance assertions will depend on these flags.  Likewise, if you
-       run  this  command  with  --auto,  the balance assertions will probably
-       always require --auto.
-
-       Examples:
-
-       Carrying asset/liability balances into a new file for 2019:
-
-              $ hledger close -f 2018.journal -e 2019 assets liabilities --open
-                  # (copy/paste the output to the start of your 2019 journal file)
-              $ hledger close -f 2018.journal -e 2019 assets liabilities --close
-                  # (copy/paste the output to the end of your 2018 journal file)
-
-       Now:
-
-              $ hledger bs -f 2019.journal                   # one file - balances are correct
-              $ hledger bs -f 2018.journal -f 2019.journal   # two files - balances still correct
-              $ hledger bs -f 2018.journal not:desc:closing  # to see year-end balances, must exclude closing txn
-
-       Transactions spanning the closing date can complicate matters, breaking
-       balance assertions:
-
-              2018/12/30 a purchase made in 2018, clearing the following year
-                  expenses:food          5
-                  assets:bank:checking  -5  ; [2019/1/2]
-
-       Here's one way to resolve that:
-
-              ; in 2018.journal:
-              2018/12/30 a purchase made in 2018, clearing the following year
-                  expenses:food          5
-                  liabilities:pending
-
-              ; in 2019.journal:
-              2019/1/2 clearance of last year's pending transactions
-                  liabilities:pending    5 = 0
-                  assets:checking
-
-   codes
-       codes
-       List the codes seen in transactions, in the order parsed.
-
-       This  command prints the value of each transaction's code field, in the
-       order transactions were parsed.  The transaction code  is  an  optional
-       value  written  in  parentheses between the date and description, often
-       used to store a cheque number, order number or similar.
-
-       Transactions aren't required to have a code, and missing or empty codes
-       will  not  be shown by default.  With the -E/--empty flag, they will be
-       printed as blank lines.
-
-       You can add a query to select a subset of transactions.
-
-       Examples:
-
-              1/1 (123)
-               (a)  1
-
-              1/1 ()
-               (a)  1
-
-              1/1
-               (a)  1
-
-              1/1 (126)
-               (a)  1
-
-              $ hledger codes
-              123
-              124
-              126
-
-              $ hledger codes -E
-              123
-              124
-
-
-              126
-
-   commodities
-       commodities
-       List all commodity/currency symbols used or declared in the journal.
-
-   descriptions
-       descriptions
-       List the unique descriptions that appear in transactions.
-
-       This command lists the unique descriptions that appear in transactions,
-       in  alphabetic order.  You can add a query to select a subset of trans-
-       actions.
-
-       Example:
-
-              $ hledger descriptions
-              Store Name
-              Gas Station | Petrol
-              Person A
-
-   diff
-       diff
-       Compares a particular account's transactions in two  input  files.   It
-       shows any transactions to this account which are in one file but not in
-       the other.
-
-       More precisely, for each posting affecting this account in either file,
-       it  looks for a corresponding posting in the other file which posts the
-       same amount to the same  account  (ignoring  date,  description,  etc.)
-       Since postings not transactions are compared, this also works when mul-
-       tiple bank transactions have been combined into a single journal entry.
-
-       This is useful eg if you have downloaded an account's transactions from
-       your bank (eg as CSV data).  When hledger and your bank disagree  about
-       the account balance, you can compare the bank data with your journal to
-       find out the cause.
-
-       Examples:
-
-              $ hledger diff -f $LEDGER_FILE -f bank.csv assets:bank:giro
-              These transactions are in the first file only:
-
-              2014/01/01 Opening Balances
-                  assets:bank:giro              EUR ...
-                  ...
-                  equity:opening balances       EUR -...
-
-              These transactions are in the second file only:
-
-   files
-       files
-       List all files included in the journal.  With a  REGEX  argument,  only
-       file  names matching the regular expression (case sensitive) are shown.
-
-   help
-       help
-       Show the hledger user manual in  one  of  several  formats,  optionally
-       positioned  at  a  given TOPIC (if possible).  TOPIC is any heading, or
-       heading prefix, in the manual.  Some examples: commands,  print,  'auto
-       postings', periodic.
-
-       This  command  shows  the user manual built in to this hledger version.
-       It can be useful if the correct version of the hledger manual,  or  the
-       usual viewing tools, are not installed on your system.
-
-       By default it uses the best viewer it can find in $PATH, in this order:
-       info, man, $PAGER (unless a topic is specified), less, or stdout.  When
-       run non-interactively, it always uses stdout.  Or you can select a par-
-       ticular viewer with the -i (info), -m (man), or -p (pager) flags.
-
-   import
-       import
-       Read new transactions added to each FILE since last run, and  add  them
-       to  the  main journal file.  Or with --dry-run, just print the transac-
-       tions that would be added.  Or with --catchup, just  mark  all  of  the
-       FILEs' transactions as imported, without actually importing any.
-
-       Unlike  other hledger commands, with import the journal file is an out-
-       put file, and will be modified, though only by appending (existing data
-       will  not  be changed).  The input files are specified as arguments, so
-       to import one or more CSV files to your  main  journal,  you  will  run
-       hledger import bank.csv or perhaps hledger import *.csv.
-
-       Note you can import from any file format, though CSV files are the most
-       common import source, and these docs focus on that case.
-
-   Deduplication
-       As a convenience import does deduplication while reading  transactions.
-       This does not mean "ignore transactions that look the same", but rather
-       "ignore transactions that have been seen before".  This is intended for
-       when  you  are  periodically  importing  foreign data which may contain
-       already-imported transactions.  So eg, if every day you  download  bank
-       CSV  files containing redundant data, you can safely run hledger import
-       bank.csv and only new transactions will be imported.  (import is  idem-
-       potent.)
-
-       Since  the  items  being  read (CSV records, eg) often do not come with
-       unique identifiers, hledger detects new transactions by date,  assuming
-       that:
-
-       1. new items always have the newest dates
-
-       2. item dates do not change across reads
-
-       3. and  items  with  the  same  date  remain in the same relative order
-          across reads.
-
-       These are often true of CSV files representing  transactions,  or  true
-       enough  so  that it works pretty well in practice.  1 is important, but
-       violations of 2 and 3 amongst the old transactions won't matter (and if
-       you  import  often, the new transactions will be few, so less likely to
-       be the ones affected).
-
-       hledger remembers the latest date processed in each input file by  sav-
-       ing a hidden ".latest" state file in the same directory.  Eg when read-
-       ing finance/bank.csv, it will look for  and  update  the  finance/.lat-
-       est.bank.csv  state file.  The format is simple: one or more lines con-
-       taining the same ISO-format date (YYYY-MM-DD),  meaning  "I  have  pro-
-       cessed  transactions  up  to  this  date, and this many of them on that
-       date." Normally you won't see or manipulate these state files yourself.
-       But  if  needed,  you  can  delete  them to reset the state (making all
-       transactions "new"), or you can construct them to "catch up" to a  cer-
-       tain date.
-
-       Note  deduplication  (and  updating of state files) can also be done by
-       print --new, but this is less often used.
-
-   Import testing
-       With --dry-run, the transactions that will be imported are  printed  to
-       the terminal, without updating your journal or state files.  The output
-       is valid journal format, like the print command, so  you  can  re-parse
-       it.   Eg,  to  see any importable transactions which CSV rules have not
-       categorised:
-
-              $ hledger import --dry bank.csv | hledger -f- -I print unknown
-
-       or (live updating):
-
-              $ ls bank.csv* | entr bash -c 'echo ====; hledger import --dry bank.csv | hledger -f- -I print unknown'
-
-   Importing balance assignments
-       Entries added by import will have their posting amounts  made  explicit
-       (like  hledger  print  -x).  This means that any balance assignments in
-       imported files must be evaluated; but, imported files don't get to  see
-       the  main file's account balances.  As a result, importing entries with
-       balance assignments (eg from an institution that provides only balances
-       and  not  posting  amounts)  will  probably  generate incorrect posting
-       amounts.  To avoid this problem, use print instead of import:
-
-              $ hledger print IMPORTFILE [--new] >> $LEDGER_FILE
-
-       (If you think import should leave amounts  implicit  like  print  does,
-       please test it and send a pull request.)
-
-   Commodity display styles
-       Imported amounts will be formatted according to the canonical commodity
-       styles (declared or inferred) in the main journal file.
-
-   incomestatement
-       incomestatement, is
-
-       This  command  displays  an  income  statement,  showing  revenues  and
-       expenses  during  one  or  more periods.  Amounts are shown with normal
-       positive sign, as in conventional financial statements.
-
-       The revenue and expense accounts shown are those accounts declared with
-       the  Revenue  or  Expense  type, or otherwise all accounts under a top-
-       level revenue or income or expense account (case  insensitive,  plurals
-       allowed).
-
-       Example:
-
-              $ hledger incomestatement
-              Income Statement
-
-              Revenues:
-                               $-2  income
-                               $-1    gifts
-                               $-1    salary
-              --------------------
-                               $-2
-
-              Expenses:
-                                $2  expenses
-                                $1    food
-                                $1    supplies
-              --------------------
-                                $2
-
-              Total:
-              --------------------
-                                 0
-
-       This command is a higher-level variant of the balance command, and sup-
-       ports many of that command's features, such  as  multi-period  reports.
-       It is similar to hledger balance '(revenues|income)' expenses, but with
-       smarter account detection, and  revenues/income  displayed  with  their
-       sign flipped.
-
-       This  command  also  supports  the output destination and output format
-       options The output formats supported are txt, csv, html,  and  (experi-
-       mental) json.
-
-   notes
-       notes
-       List the unique notes that appear in transactions.
-
-       This  command  lists  the  unique notes that appear in transactions, in
-       alphabetic order.  You can add a query to select a subset  of  transac-
-       tions.   The  note is the part of the transaction description after a |
-       character (or if there is no |, the whole description).
-
-       Example:
-
-              $ hledger notes
-              Petrol
-              Snacks
-
-   payees
-       payees
-       List the unique payee/payer names that appear in transactions.
-
-       This command lists unique payee/payer names which  have  been  declared
-       with  payee  directives  (--declared), used in transaction descriptions
-       (--used), or both (the default).
-
-       The payee/payer is the part of the transaction description before  a  |
-       character (or if there is no |, the whole description).
-
-       You  can  add query arguments to select a subset of transactions.  This
-       implies --used.
-
-       Example:
-
-              $ hledger payees
-              Store Name
-              Gas Station
-              Person A
-
-   prices
-       prices
-       Print market price directives from the  journal.   With  --costs,  also
-       print  synthetic  market  prices  based  on  transaction  prices.  With
-       --inverted-costs,  also  print  inverse  prices  based  on  transaction
-       prices.   Prices  (and  postings providing prices) can be filtered by a
-       query.  Price amounts are always displayed with their full precision.
-
-   print
-       print
-       Show transaction journal entries, sorted by date.
-
-       The print command displays full journal entries (transactions) from the
-       journal file, sorted by date (or with --date2, by secondary date).
-
-       Amounts  are shown mostly normalised to commodity display style, eg the
-       placement of commodity symbols will be consistent.  All of their  deci-
-       mal places are shown, as in the original journal entry (with one alter-
-       ation: in some cases trailing zeroes are added.)
-
-       Amounts are shown right-aligned within each transaction (but not across
-       all transactions).
-
-       Directives  and  inter-transaction  comments  are not shown, currently.
-       This means the print command is somewhat lossy, and if you are using it
-       to  reformat  your  journal  you should take care to also copy over the
-       directives and file-level comments.
-
-       Eg:
-
-              $ hledger print
-              2008/01/01 income
-                  assets:bank:checking            $1
-                  income:salary                  $-1
-
-              2008/06/01 gift
-                  assets:bank:checking            $1
-                  income:gifts                   $-1
-
-              2008/06/02 save
-                  assets:bank:saving              $1
-                  assets:bank:checking           $-1
-
-              2008/06/03 * eat & shop
-                  expenses:food                $1
-                  expenses:supplies            $1
-                  assets:cash                 $-2
-
-              2008/12/31 * pay off
-                  liabilities:debts               $1
-                  assets:bank:checking           $-1
-
-       print's output is usually a valid hledger journal, and you can  process
-       it again with a second hledger command.  This can be useful for certain
-       kinds of search, eg:
-
-              # Show running total of food expenses paid from cash.
-              # -f- reads from stdin. -I/--ignore-assertions is sometimes needed.
-              $ hledger print assets:cash | hledger -f- -I reg expenses:food
-
-       There are some situations where print's output can become unparseable:
-
-       o Valuation affects posting amounts but not balance assertion  or  bal-
-         ance assignment amounts, potentially causing those to fail.
-
-       o Auto postings can generate postings with too many missing amounts.
-
-       Normally, the journal entry's explicit or implicit amount style is pre-
-       served.  For example, when an amount is omitted in the journal, it will
-       not  appear  in  the  output.   Similarly,  when a transaction price is
-       implied but not written, it will not appear in the output.  You can use
-       the  -x/--explicit  flag  to  make  all  amounts and transaction prices
-       explicit, which can be useful for troubleshooting or  for  making  your
-       journal more readable and robust against data entry errors.  -x is also
-       implied by using any of -B,-V,-X,--value.
-
-       Note, -x/--explicit will cause postings with a  multi-commodity  amount
-       (these  can  arise  when  a multi-commodity transaction has an implicit
-       amount) to be split into multiple  single-commodity  postings,  keeping
-       the output parseable.
-
-       With  -B/--cost,  amounts with transaction prices are converted to cost
-       using that price.  This can be used for troubleshooting.
-
-       With -m/--match and a STR argument, print will show at most one  trans-
-       action:  the  one  one whose description is most similar to STR, and is
-       most recent.  STR should contain at least two characters.  If there  is
-       no similar-enough match, no transaction will be shown.
-
-       With  --new, hledger prints only transactions it has not seen on a pre-
-       vious run.  This uses the same deduplication system as the import  com-
-       mand.  (See import's docs for details.)
-
-       This  command  also  supports  the output destination and output format
-       options The output formats supported are txt, csv,  and  (experimental)
-       json and sql.
-
-       Here's an example of print's CSV output:
-
-              $ hledger print -Ocsv
-              "txnidx","date","date2","status","code","description","comment","account","amount","commodity","credit","debit","posting-status","posting-comment"
-              "1","2008/01/01","","","","income","","assets:bank:checking","1","$","","1","",""
-              "1","2008/01/01","","","","income","","income:salary","-1","$","1","","",""
-              "2","2008/06/01","","","","gift","","assets:bank:checking","1","$","","1","",""

-       o There  is  one  CSV record per posting, with the parent transaction's
-         fields repeated.
-
-       o The "txnidx" (transaction index) field shows which postings belong to
-         the  same transaction.  (This number might change if transactions are
-         reordered within the file, files are parsed/included in  a  different
-         order, etc.)
-
-       o The  amount  is  separated into "commodity" (the symbol) and "amount"
-         (numeric quantity) fields.
-
-       o The numeric amount is repeated in either the "credit" or "debit" col-
-         umn,  for convenience.  (Those names are not accurate in the account-
-         ing sense; it just puts negative amounts under  credit  and  zero  or
-         greater amounts under debit.)
-
-   print-unique
-       print-unique
-       Print transactions which do not reuse an already-seen description.
-
-       Example:
-
-              $ cat unique.journal
-              1/1 test
-               (acct:one)  1
-              2/2 test
-               (acct:two)  2
-              $ LEDGER_FILE=unique.journal hledger print-unique
-              (-f option not supported)
-              2015/01/01 test
-                  (acct:one)             1
-
-   register
-       register, reg
-       Show postings and their running total.
-
-       The register command displays matched postings, across all accounts, in
-       date order, with their running total  or  running  historical  balance.
-       (See  also the aregister command, which shows matched transactions in a
-       specific account.)
-
-       register normally shows line per posting, but note that multi-commodity
-       amounts will occupy multiple lines (one line per commodity).
-
-       It  is  typically  used with a query selecting a particular account, to
-       see that account's activity:
-
-              $ hledger register checking
-              2008/01/01 income               assets:bank:checking            $1           $1
-              2008/06/01 gift                 assets:bank:checking            $1           $2
-              2008/06/02 save                 assets:bank:checking           $-1           $1
-              2008/12/31 pay off              assets:bank:checking           $-1            0
-
-       With --date2, it shows and sorts by secondary date instead.
-
-       The --historical/-H flag adds the balance from  any  undisplayed  prior
-       postings  to  the  running  total.  This is useful when you want to see
-       only recent activity, with a historically accurate running balance:
-
-              $ hledger register checking -b 2008/6 --historical
-              2008/06/01 gift                 assets:bank:checking            $1           $2
-              2008/06/02 save                 assets:bank:checking           $-1           $1
-              2008/12/31 pay off              assets:bank:checking           $-1            0
-
-       The --depth option limits the amount of sub-account detail displayed.
-
-       The --average/-A flag shows the running average posting amount  instead
-       of the running total (so, the final number displayed is the average for
-       the whole report period).  This flag implies --empty (see  below).   It
-       is  affected  by  --historical.   It  works  best when showing just one
-       account and one commodity.
-
-       The --related/-r flag shows the other postings in the  transactions  of
-       the postings which would normally be shown.
-
-       The  --invert flag negates all amounts.  For example, it can be used on
-       an income account where amounts are normally displayed as negative num-
-       bers.   It's  also  useful  to  show  postings  on the checking account
-       together with the related account:
-
-              $ hledger register --related --invert assets:checking
-
-       With a reporting interval, register shows  summary  postings,  one  per
-       interval, aggregating the postings to each account:
-
-              $ hledger register --monthly income
-              2008/01                 income:salary                          $-1          $-1
-              2008/06                 income:gifts                           $-1          $-2
-
-       Periods  with no activity, and summary postings with a zero amount, are
-       not shown by default; use the --empty/-E flag to see them:
-
-              $ hledger register --monthly income -E
-              2008/01                 income:salary                          $-1          $-1
-              2008/02                                                          0          $-1
-              2008/03                                                          0          $-1
-              2008/04                                                          0          $-1
-              2008/05                                                          0          $-1
-              2008/06                 income:gifts                           $-1          $-2
-              2008/07                                                          0          $-2
-              2008/08                                                          0          $-2
-              2008/09                                                          0          $-2
-              2008/10                                                          0          $-2
-              2008/11                                                          0          $-2
-              2008/12                                                          0          $-2
-
-       Often, you'll want to see just one  line  per  interval.   The  --depth
-       option helps with this, causing subaccounts to be aggregated:
-
-              $ hledger register --monthly assets --depth 1h
-              2008/01                 assets                                  $1           $1
-              2008/06                 assets                                 $-1            0
-              2008/12                 assets                                 $-1          $-1
-
-       Note  when using report intervals, if you specify start/end dates these
-       will be adjusted outward if necessary to  contain  a  whole  number  of
-       intervals.   This  ensures  that  the first and last intervals are full
-       length and comparable to the others in the report.
-
-   Custom register output
-       register uses the full terminal width by default,  except  on  windows.
-       You  can override this by setting the COLUMNS environment variable (not
-       a bash shell variable) or by using the --width/-w option.
-
-       The description and account columns normally share  the  space  equally
-       (about  half  of  (width  - 40) each).  You can adjust this by adding a
-       description width  as  part  of  --width's  argument,  comma-separated:
-       --width W,D .  Here's a diagram (won't display correctly in --help):
-
-              <--------------------------------- width (W) ---------------------------------->
-              date (10)  description (D)       account (W-41-D)     amount (12)   balance (12)
-              DDDDDDDDDD dddddddddddddddddddd  aaaaaaaaaaaaaaaaaaa  AAAAAAAAAAAA  AAAAAAAAAAAA
-
-       and some examples:
-
-              $ hledger reg                     # use terminal width (or 80 on windows)
-              $ hledger reg -w 100              # use width 100
-              $ COLUMNS=100 hledger reg         # set with one-time environment variable
-              $ export COLUMNS=100; hledger reg # set till session end (or window resize)
-              $ hledger reg -w 100,40           # set overall width 100, description width 40
-              $ hledger reg -w $COLUMNS,40      # use terminal width, & description width 40
-
-       This  command  also  supports  the output destination and output format
-       options The output formats supported are txt, csv,  and  (experimental)
-       json.
-
-   register-match
-       register-match
-       Print the one posting whose transaction description is closest to DESC,
-       in the style of the register command.  If there  are  multiple  equally
-       good  matches,  it  shows the most recent.  Query options (options, not
-       arguments) can be used to restrict the  search  space.   Helps  ledger-
-       autosync detect already-seen transactions when importing.
-
-   rewrite
-       rewrite
-       Print all transactions, rewriting the postings of matched transactions.
-       For now the only rewrite available is adding new postings,  like  print
-       --auto.
-
-       This is a start at a generic rewriter of transaction entries.  It reads
-       the default journal and prints the transactions, like print,  but  adds
-       one or more specified postings to any transactions matching QUERY.  The
-       posting amounts can be fixed, or a multiplier of the existing  transac-
-       tion's first posting amount.
-
-       Examples:
-
-              $ hledger-rewrite.hs ^income --add-posting '(liabilities:tax)  *.33  ; income tax' --add-posting '(reserve:gifts)  $100'
-              $ hledger-rewrite.hs expenses:gifts --add-posting '(reserve:gifts)  *-1"'
-              $ hledger-rewrite.hs -f rewrites.hledger
-
-       rewrites.hledger may consist of entries like:
-
-              = ^income amt:<0 date:2017
-                (liabilities:tax)  *0.33  ; tax on income
-                (reserve:grocery)  *0.25  ; reserve 25% for grocery
-                (reserve:)  *0.25  ; reserve 25% for grocery
-
-       Note  the  single  quotes to protect the dollar sign from bash, and the
-       two spaces between account and amount.
-
-       More:
-
-              $ hledger rewrite -- [QUERY]        --add-posting "ACCT  AMTEXPR" ...
-              $ hledger rewrite -- ^income        --add-posting '(liabilities:tax)  *.33'
-              $ hledger rewrite -- expenses:gifts --add-posting '(budget:gifts)  *-1"'
-              $ hledger rewrite -- ^income        --add-posting '(budget:foreign currency)  *0.25 JPY; diversify'
-
-       Argument for --add-posting option is a  usual  posting  of  transaction
-       with  an  exception  for amount specification.  More precisely, you can
-       use '*' (star symbol) before the amount to indicate that that this is a
-       factor  for  an  amount  of  original  matched  posting.  If the amount
-       includes a commodity name, the new posting amount will be  in  the  new
-       commodity;  otherwise,  it will be in the matched posting amount's com-
-       modity.
-
-   Re-write rules in a file
-       During the run this tool will execute  so  called  "Automated  Transac-
-       tions" found in any journal it process.  I.e instead of specifying this
-       operations in command line you can put them in a journal file.
-
-              $ rewrite-rules.journal
-
-       Make contents look like this:
-
-              = ^income
-                  (liabilities:tax)  *.33
-
-              = expenses:gifts
-                  budget:gifts  *-1
-                  assets:budget  *1
-
-       Note that '=' (equality symbol) that is used instead of date in  trans-
-       actions you usually write.  It indicates the query by which you want to
-       match the posting to add new ones.
-
-              $ hledger rewrite -- -f input.journal -f rewrite-rules.journal > rewritten-tidy-output.journal
-
-       This is something similar to the commands pipeline:
-
-              $ hledger rewrite -- -f input.journal '^income' --add-posting '(liabilities:tax)  *.33' \
-                | hledger rewrite -- -f - expenses:gifts      --add-posting 'budget:gifts  *-1'       \
-                                                              --add-posting 'assets:budget  *1'       \
-                > rewritten-tidy-output.journal
-
-       It is important to understand that relative order of  such  entries  in
-       journal  is important.  You can re-use result of previously added post-
-       ings.
-
-   Diff output format
-       To use this tool for batch modification of your journal files  you  may
-       find useful output in form of unified diff.
-
-              $ hledger rewrite -- --diff -f examples/sample.journal '^income' --add-posting '(liabilities:tax)  *.33'
-
-       Output might look like:

-   rewrite vs. print --auto
-       This  command  predates  print --auto, and currently does much the same
-       thing, but with these differences:
-
-       o with multiple files, rewrite lets rules in any file affect all  other
-         files.   print  --auto  uses standard directive scoping; rules affect
-         only child files.
-
-       o rewrite's query limits which transactions can be rewritten;  all  are
-         printed.  print --auto's query limits which transactions are printed.
-
-       o rewrite applies rules specified on command line or  in  the  journal.
-         print --auto applies rules specified in the journal.
-
-   roi
-       roi
-       Shows  the  time-weighted (TWR) and money-weighted (IRR) rate of return
-       on your investments.
-
-       At a minimum, you need to supply  a  query  (which  could  be  just  an
-       account  name)  to  select  your  investment(s) with --inv, and another
-       query to identify your profit and loss transactions with --pnl.
-
-       If you do not record changes in the value of your investment  manually,
-       or  do  not  require  computation  of time-weighted return (TWR), --pnl
-       could be an empty query (--pnl "" or --pnl STR where STR does not match
-       any of your accounts).
-
-       This  command  will compute and display the internalized rate of return
-       (IRR) and time-weighted rate of return (TWR) for your  investments  for
-       the  time period requested.  Both rates of return are annualized before
-       display, regardless of the length of reporting interval.
-
-       Price directives will be taken into account if you  supply  appropriate
-       --cost or --value flags (see VALUATION).
-
-       Note, in some cases this report can fail, for these reasons:
-
-       o Error  (NotBracketed): No solution for Internal Rate of Return (IRR).
-         Possible causes: IRR  is  huge  (>1000000%),  balance  of  investment
-         becomes negative at some point in time.
-
-       o Error  (SearchFailed):  Failed  to find solution for Internal Rate of
-         Return (IRR).  Either search does not converge to a solution, or con-
-         verges too slowly.
-
-       Examples:
-
-       o Using   roi   to  compute  total  return  of  investment  in  stocks:

-   Spaces and special characters in --inv and --pnl
-       Note that --inv and --pnl's argument is a query, and queries could have

-
-       To indicate that all search terms form  single  command-line  argument,
-       you will need to put them in quotes (see Special characters):
-
-              $ hledger roi --inv 'term1 term2 term3 ...'
-
-       If  any  query  terms contain spaces themselves, you will need an extra
-       level of nested quoting, eg:
-
-              $ hledger roi --inv="'Assets:Test 1'" --pnl="'Equity:Unrealized Profit and Loss'"
-
-   Semantics of --inv and --pnl
-       Query supplied to --inv has to match all transactions that are  related
-       to your investment.  Transactions not matching --inv will be ignored.
-
-       In these transactions, ROI will conside postings that match --inv to be
-       "investment postings" and other postings (not matching --inv)  will  be
-       sorted  into  two categories: "cash flow" and "profit and loss", as ROI
-       needs to know which part of the investment value is your  contributions
-       and which is due to the return on investment.
-
-       o "Cash  flow"  is  depositing  or withdrawing money, buying or selling
-         assets, or otherwise converting between your investment commodity and
-         any other commodity.  Example:
-
-                2019-01-01 Investing in Snake Oil
-                  assets:cash          -$100
-                  investment:snake oil
-
-                2020-01-01 Selling my Snake Oil
-                  assets:cash           $10
-                  investment:snake oil  = 0
-
-       o "Profit and loss" is change in the value of your investment:
-
-                2019-06-01 Snake Oil falls in value
-                  investment:snake oil  = $57
-                  equity:unrealized profit or loss
-
-       All  non-investment postings are assumed to be "cash flow", unless they
-       match --pnl query.  Changes in value of your investment due to  "profit
-       and  loss"  postings  will  be  considered  as  part of your investment
-       return.
-
-       Example: if you use --inv snake --pnl equity:unrealized, then  postings
-       in the example below would be classifed as:
-
-              2019-01-01 Snake Oil #1
-                assets:cash          -$100   ; cash flow posting
-                investment:snake oil         ; investment posting
-
-              2019-03-01 Snake Oil #2
-                equity:unrealized pnl  -$100 ; profit and loss posting
-                snake oil                    ; investment posting
-
-              2019-07-01 Snake Oil #3
-                equity:unrealized pnl        ; profit and loss posting
-                cash          -$100          ; cash flow posting
-                snake oil     $50            ; investment posting

-   IRR and TWR explained
-       "ROI"  stands  for "return on investment".  Traditionally this was com-
-       puted as a difference between current value of investment and its  ini-
-       tial value, expressed in percentage of the initial value.
-
-       However, this approach is only practical in simple cases, where invest-
-       ments receives no in-flows or out-flows of money,  and  where  rate  of
-       growth is fixed over time.  For more complex scenarios you need differ-
-       ent ways to compute rate of return, and this command implements two  of
-       them: IRR and TWR.
-
-       Internal  rate of return, or "IRR" (also called "money-weighted rate of
-       return")  takes  into  account  effects  of  in-flows  and   out-flows.
-       Naively, if you are withdrawing from your investment, your future gains
-       would be smaller (in absolute numbers), and will be a smaller  percent-
-       age  of  your initial investment, and if you are adding to your invest-
-       ment, you will receive bigger absolute gains (but probably at the  same
-       rate  of  return).   IRR  is  a  way to compute rate of return for each
-       period between in-flow or out-flow of money, and then combine them in a
-       way  that gives you a compound annual rate of return that investment is
-       expected to generate.
-
-       As mentioned before, in-flows and out-flows would be any cash that  you
-       personally put in or withdraw, and for the "roi" command, these are the
-       postings that match the query in the--inv argument and  NOT  match  the
-       query in the--pnl argument.
-
-       If  you  manually  record  changes  in  the value of your investment as
-       transactions that balance them against "profit and loss"  (or  "unreal-
-       ized  gains") account or use price directives, then in order for IRR to
-       compute the precise effect of your in-flows and out-flows on  the  rate
-       of  return, you will need to record the value of your investement on or
-       close to the days when in- or out-flows occur.
-
-       In technical terms, IRR uses the same approach as  computation  of  net
-       present value, and tries to find a discount rate that makes net present
-       value of all the cash flows of your investment to add up to zero.  This
-       could  be hard to wrap your head around, especially if you haven't done
-       discounted cash flow analysis before.  Implementation of IRR in hledger
-       should produce results that match the XIRR formula in Excel.
-
-       Second  way  to  compute  rate of return that roi command implements is
-       called "time-weighted rate of return" or "TWR".  Like IRR, it will also
-       break  the  history  of  your investment into periods between in-flows,
-       out-flows and value changes, to compute rate of return per each  period
-       and  then a compound rate of return.  However, internal workings of TWR
-       are quite different.
-
-       TWR represents your investment as an imaginary "unit  fund"  where  in-
-       flows/  out-flows  lead to buying or selling "units" of your investment
-       and changes in its value change the value of "investment unit".  Change
-       in  "unit  price" over the reporting period gives you rate of return of
-       your investment.

-   stats
-       stats
-       Show some journal statistics.
-
-       The stats command displays summary information for the  whole  journal,
-       or  a matched part of it.  With a reporting interval, it shows a report
-       for each report period.
-
-       Example:
-
-              $ hledger stats
-              Main journal file        : /src/hledger/examples/sample.journal
-              Included journal files   :
-              Transactions span        : 2008-01-01 to 2009-01-01 (366 days)
-              Last transaction         : 2008-12-31 (2333 days ago)
-              Transactions             : 5 (0.0 per day)
-              Transactions last 30 days: 0 (0.0 per day)
-              Transactions last 7 days : 0 (0.0 per day)
-              Payees/descriptions      : 5
-              Accounts                 : 8 (depth 3)
-              Commodities              : 1 ($)
-              Market prices            : 12 ($)
-
-       This command also supports output destination and output format  selec-
-       tion.
-
-   tags
-       tags
-       List  the  unique tag names used in the journal.  With a TAGREGEX argu-
-       ment, only tag names matching the regular expression (case insensitive)
-       are  shown.  With QUERY arguments, only transactions matching the query
-       are considered.
-
-       With the --values flag, the tags' unique values are listed instead.
-
-       With --parsed flag, all tags or values are shown in the order they  are
-       parsed from the input data, including duplicates.
-
-       With  -E/--empty,  any blank/empty values will also be shown, otherwise
-       they are omitted.
-
-   test
-       test
-       Run built-in unit tests.
-
-       This command runs the unit tests built in to hledger  and  hledger-lib,
-       printing  the results on stdout.  If any test fails, the exit code will
-       be non-zero.
-
-       This is mainly used by hledger developers, but you can also use  it  to
-       sanity-check  the  installed  hledger executable on your platform.  All
-       tests are expected to pass - if you ever see a failure,  please  report
-       as a bug!
-
-       This command also accepts tasty test runner options, written after a --
-       (double hyphen).  Eg to run only the tests in Hledger.Data.Amount, with
-       ANSI colour codes disabled:
-
-              $ hledger test -- -pData.Amount --color=never
-
-       For  help  on these, see https://github.com/feuerbach/tasty#options (--
-       --help currently doesn't show them).
-
-   About add-on commands
-       Add-on commands are programs or scripts in your PATH
-
-       o whose name starts with hledger-
-
-       o whose name ends with a  recognised  file  extension:  .bat,.com,.exe,
-         .hs,.lhs,.pl,.py,.rb,.rkt,.sh or none
-
-       o and (on unix, mac) which are executable by the current user.
-
-       Add-ons  are  a relatively easy way to add local features or experiment
-       with new ideas.  They can be  written  in  any  language,  but  haskell
-       scripts  have  a  big  advantage: they can use the same hledger library
-       functions that built-in commands use for command-line options,  parsing
-       and  reporting.   Some experimental/example add-on scripts can be found
-       in the hledger repo's bin/ directory.
-
-       Note in a hledger command line, add-on command flags must have a double
-       dash (--) preceding them.  Eg you must write:
-
-              $ hledger web -- --serve
-
-       and not:
-
-              $ hledger web --serve
-
-       (because the --serve flag belongs to hledger-web, not hledger).
-
-       The -h/--help and --version flags don't require --.
-
-       If you have any trouble with this, remember you can always run the add-
-       on program directly, eg:
-
-              $ hledger-web --serve
-
-JOURNAL FORMAT
-       hledger's default file format, representing a General Journal.
-
-       hledger's usual data source is a plain  text  file  containing  journal
-       entries  in  hledger  journal  format.  This file represents a standard
-       accounting general journal.  I use file names ending in  .journal,  but
-       that's not required.  The journal file contains a number of transaction
-       entries, each describing a transfer of money (or any commodity) between
-       two or more named accounts, in a simple format readable by both hledger
-       and humans.
-
-       hledger's journal format is a compatible subset,  mostly,  of  ledger's
-       journal  format,  so  hledger  can  work with compatible ledger journal
-       files as well.  It's safe, and encouraged,  to  run  both  hledger  and
-       ledger on the same journal file, eg to validate the results you're get-
-       ting.
-
-       You can use hledger without learning any more about this file; just use
-       the add or web or import commands to create and update it.
-
-       Many users, though, edit the journal file with a text editor, and track
-       changes with a version control system such as git.  Editor addons  such
-       as  ledger-mode  or  hledger-mode  for  Emacs,  vim-ledger for Vim, and
-       hledger-vscode for Visual Studio Code, make this easier, adding colour,
-       formatting, tab completion, and useful commands.  See Editor configura-
-       tion at hledger.org for the full list.
-
-       Here's a description of each part of the  file  format  (and  hledger's
-       data  model).   These  are  mostly in the order you'll use them, but in
-       some cases related concepts have been grouped together for easy  refer-
-       ence,  or  linked before they are introduced, so feel free to skip over
-       anything that looks unnecessary right now.
-
-   Transactions
-       Transactions are the main unit of information in a journal file.   They
-       represent  events, typically a movement of some quantity of commodities
-       between two or more named accounts.
-
-       Each transaction is recorded as a journal entry, beginning with a  sim-
-       ple  date  in  column  0.  This can be followed by any of the following
-       optional fields, separated by spaces:
-
-       o a status character (empty, !, or *)
-
-       o a code (any short number or text, enclosed in parentheses)
-
-       o a description (any remaining text until end of line or a semicolon)
-
-       o a comment (any remaining text following  a  semicolon  until  end  of
-         line, and any following indented lines beginning with a semicolon)
-
-       o 0 or more indented posting lines, describing what was transferred and
-         the accounts involved (indented comment lines are also  allowed,  but
-         not blank lines or non-indented lines).
-
-       Here's a simple journal file containing one transaction:
-
-              2008/01/01 income
-                assets:bank:checking   $1
-                income:salary         $-1
-
-   Dates
-   Simple dates
-       Dates  in  the  journal  file  use  simple  dates format: YYYY-MM-DD or
-       YYYY/MM/DD or YYYY.MM.DD, with leading zeros optional.  The year may be
-       omitted,  in  which case it will be inferred from the context: the cur-
-       rent transaction, the default year set with a default  year  directive,
-       or   the  current  date  when  the  command  is  run.   Some  examples:
-       2010-01-31, 2010/01/31, 2010.1.31, 1/31.
-
-       (The UI also accepts simple dates, as well as the more  flexible  smart
-       dates documented in the hledger manual.)
-
-   Secondary dates
-       Real-life  transactions  sometimes  involve more than one date - eg the
-       date you write a cheque, and the date it clears in your bank.  When you
-       want  to  model this, for more accurate daily balances, you can specify
-       individual posting dates.
-
-       Or, you can use the older secondary date feature (Ledger calls it  aux-
-       iliary  date or effective date).  Note: we support this for compatibil-
-       ity, but I usually recommend avoiding this feature; posting  dates  are
-       almost always clearer and simpler.
-
-       A secondary date is written after the primary date, following an equals
-       sign.  If the year is omitted, the  primary  date's  year  is  assumed.
-       When  running  reports, the primary (left) date is used by default, but
-       with the --date2 flag (or --aux-date  or  --effective),  the  secondary
-       (right) date will be used instead.
-
-       The  meaning of secondary dates is up to you, but it's best to follow a
-       consistent rule.  Eg "primary = the bank's clearing date,  secondary  =
-       date the transaction was initiated, if different", as shown here:
-
-              2010/2/23=2/19 movie ticket
-                expenses:cinema                   $10
-                assets:checking
-
-              $ hledger register checking
-              2010-02-23 movie ticket         assets:checking                $-10         $-10
-
-              $ hledger register checking --date2
-              2010-02-19 movie ticket         assets:checking                $-10         $-10
-
-   Posting dates
-       You  can  give  individual  postings a different date from their parent
-       transaction, by adding a posting comment containing a tag  (see  below)
-       like date:DATE.  This is probably the best way to control posting dates
-       precisely.  Eg in  this  example  the  expense  should  appear  in  May
-       reports,  and the deduction from checking should be reported on 6/1 for
-       easy bank reconciliation:
-
-              2015/5/30
-                  expenses:food     $10  ; food purchased on saturday 5/30
-                  assets:checking        ; bank cleared it on monday, date:6/1
-
-              $ hledger -f t.j register food
-              2015-05-30                      expenses:food                  $10           $10
-
-              $ hledger -f t.j register checking
-              2015-06-01                      assets:checking               $-10          $-10
-
-       DATE should be a simple date; if the year is not specified it will  use
-       the  year  of  the  transaction's date.  You can set the secondary date
-       similarly, with date2:DATE2.  The date: or  date2:  tags  must  have  a
-       valid  simple  date  value  if they are present, eg a date: tag with no
-       value is not allowed.
-
-       Ledger's earlier, more compact bracketed date syntax is also supported:
-       [DATE],  [DATE=DATE2]  or  [=DATE2].  hledger will attempt to parse any
-       square-bracketed sequence of the 0123456789/-.= characters in this way.
-       With  this  syntax, DATE infers its year from the transaction and DATE2
-       infers its year from DATE.
-
-   Status
-       Transactions, or individual postings within a transaction, can  have  a
-       status  mark,  which  is  a  single  character  before  the transaction
-       description or posting account name, separated  from  it  by  a  space,
-       indicating one of three statuses:
-
-
-       mark     status
-       ------------------
-                unmarked
-       !        pending
-       *        cleared
-
-       When  reporting,  you  can  filter  by  status  with the -U/--unmarked,
-       -P/--pending, and -C/--cleared flags; or  the  status:,  status:!,  and
-       status:* queries; or the U, P, C keys in hledger-ui.
-
-       Note,  in Ledger and in older versions of hledger, the "unmarked" state
-       is called "uncleared".  As  of  hledger  1.3  we  have  renamed  it  to
-       unmarked for clarity.
-
-       To  replicate Ledger and old hledger's behaviour of also matching pend-
-       ing, combine -U and -P.
-
-       Status marks are optional, but can be helpful eg for  reconciling  with
-       real-world accounts.  Some editor modes provide highlighting and short-
-       cuts for working with status.  Eg in Emacs ledger-mode, you can  toggle
-       transaction status with C-c C-e, or posting status with C-c C-c.
-
-       What  "uncleared", "pending", and "cleared" actually mean is up to you.
-       Here's one suggestion:
-
-
-       status       meaning
-       --------------------------------------------------------------------------
-       uncleared    recorded but not yet reconciled; needs review
-       pending      tentatively reconciled (if needed, eg during a big reconcil-
-                    iation)
-       cleared      complete, reconciled as far as possible, and considered cor-
-                    rect
-
-       With this scheme, you would use -PC to see the current balance at  your
-       bank,  -U  to  see  things which will probably hit your bank soon (like
-       uncashed checks), and no flags to see the most up-to-date state of your
-       finances.
-
-   Code
-       After  the  status mark, but before the description, you can optionally
-       write a transaction "code", enclosed in parentheses.  This  is  a  good
-       place  to record a check number, or some other important transaction id
-       or reference number.
-
-   Description
-       A transaction's description is the rest of the line following the  date
-       and  status  mark  (or  until  a comment begins).  Sometimes called the
-       "narration" in traditional bookkeeping, it can be used for whatever you
-       wish,  or  left blank.  Transaction descriptions can be queried, unlike
-       comments.
-
-   Payee and note
-       You can optionally include a | (pipe) character in descriptions to sub-
-       divide the description into separate fields for payee/payer name on the
-       left (up to the first |) and an additional  note  field  on  the  right
-       (after  the  first  |).   This may be worthwhile if you need to do more
-       precise querying and pivoting by payee or by note.

-       Lines in the journal beginning with a semicolon (;) or hash (#) or star
-       (*)  are  comments, and will be ignored.  (Star comments cause org-mode
-       nodes to be ignored, allowing emacs users to fold  and  navigate  their
-       journals with org-mode or orgstruct-mode.)
-
-       You  can  attach  comments  to  a transaction by writing them after the
-       description and/or indented on the following lines  (before  the  post-
-       ings).   Similarly, you can attach comments to an individual posting by
-       writing them after the amount and/or indented on the  following  lines.
-       Transaction and posting comments must begin with a semicolon (;).
-
-       Some examples:
-
-              # a file comment
-              ; another file comment
-              * also a file comment, useful in org/orgstruct mode
-
-              comment
-              A multiline file comment, which continues
-              until a line containing just "end comment"
-              (or end of file).
-              end comment
-
-              2012/5/14 something  ; a transaction comment
-                  ; the transaction comment, continued
-                  posting1  1  ; a comment for posting 1
-                  posting2
-                  ; a comment for posting 2
-                  ; another comment line for posting 2
-              ; a file comment (because not indented)
-
-       You  can  also  comment  larger regions of a file using comment and end
-       comment directives.
-
-   Tags
-       Tags are a way to add extra labels or labelled  data  to  postings  and
-       transactions, which you can then search or pivot on.
-
-       A  simple  tag is a word (which may contain hyphens) followed by a full
-       colon, written inside a transaction or posting comment line:
-
-              2017/1/16 bought groceries  ; sometag:
-
-       Tags can have a value, which is the text after the  colon,  up  to  the
-       next comma or end of line, with leading/trailing whitespace removed:
-
-                  expenses:food    $10 ; a-posting-tag: the tag value
-
-       Note  this  means  hledger's  tag values can not contain commas or new-
-       lines.  Ending at commas means you can write multiple short tags on one
-       line, comma separated:
-
-                  assets:checking  ; a comment containing tag1:, tag2: some value ...
-
-       Here,
-
-       o "a comment containing" is just comment text, not a tag
-
-       o "tag1" is a tag with no value
-
-       o "tag2" is another tag, whose value is "some value ..."
-
-       Tags  in  a  transaction  comment affect the transaction and all of its
-       postings, while tags in a posting comment  affect  only  that  posting.
-       For  example, the following transaction has three tags (A, TAG2, third-
-       tag) and the posting has four (those plus posting-tag):
-
-              1/1 a transaction  ; A:, TAG2:
-                  ; third-tag: a third transaction tag, <- with a value
-                  (a)  $1  ; posting-tag:
-
-       Tags are like Ledger's metadata feature, except  hledger's  tag  values
-       are simple strings.
-
-   Postings
-       A  posting  is an addition of some amount to, or removal of some amount
-       from, an account.  Each posting line begins with at least one space  or
-       tab (2 or 4 spaces is common), followed by:
-
-       o (optional) a status character (empty, !, or *), followed by a space
-
-       o (required)  an  account  name (any text, optionally containing single
-         spaces, until end of line or a double space)
-
-       o (optional) two or more spaces or tabs followed by an amount.
-
-       Positive amounts are being added to the account, negative  amounts  are
-       being removed.
-
-       The amounts within a transaction must always sum up to zero.  As a con-
-       venience, one amount may be left blank; it will be inferred  so  as  to
-       balance the transaction.
-
-       Be  sure  to  note the unusual two-space delimiter between account name
-       and amount.  This makes it easy to write account names containing  spa-
-       ces.   But if you accidentally leave only one space (or tab) before the
-       amount, the amount will be considered part of the account name.
-
-   Virtual postings
-       A posting with a parenthesised account name is called a virtual posting
-       or  unbalanced  posting,  which  means it is exempt from the usual rule
-       that a transaction's postings must balance add up to zero.
-
-       This is not part of double entry accounting, so  you  might  choose  to
-       avoid  this  feature.   Or you can use it sparingly for certain special
-       cases where it can be convenient.  Eg, you could set  opening  balances
-       without using a balancing equity account:
-
-              1/1 opening balances
-                (assets:checking)   $1000
-                (assets:savings)    $2000
-
-       A  posting  with  a bracketed account name is called a balanced virtual
-       posting.  The balanced virtual postings in a transaction must add up to
-       zero (separately from other postings).  Eg:
-
-              1/1 buy food with cash, update budget envelope subaccounts, & something else
-                assets:cash                    $-10 ; <- these balance
-                expenses:food                    $7 ; <-
-                expenses:food                    $3 ; <-
-                [assets:checking:budget:food]  $-10    ; <- and these balance
-                [assets:checking:available]     $10    ; <-
-                (something:else)                 $5       ; <- not required to balance
-
-       Ordinary  non-parenthesised,  non-bracketed  postings  are  called real
-       postings.  You can exclude  virtual  postings  from  reports  with  the
-       -R/--real flag or real:1 query.
-
-   Account names
-       Account  names  typically have several parts separated by a full colon,
-       from which hledger derives a hierarchical chart of accounts.  They  can
-       be  anything you like, but in finance there are traditionally five top-
-       level accounts: assets, liabilities, revenue, expenses, and equity.
-
-       Account names may contain single spaces,  eg:  assets:accounts  receiv-
-       able.   Because  of  this,  they must always be followed by two or more
-       spaces (or newline).
-
-       Account names can be aliased.
-
-   Amounts
-       After the account  name,  there  is  usually  an  amount.   (Important:
-       between account name and amount, there must be two or more spaces.)
-
-       hledger's  amount  format is flexible, supporting several international
-       formats.  Here are some examples.  Amounts have a  number  (the  "quan-
-       tity"):
-
-              1
-
-       ..and usually a currency symbol or commodity name (more on this below),
-       to the left or right of the quantity,  with  or  without  a  separating
-       space:
-
-              $1
-              4000 AAPL
-              3 "green apples"
-
-       Amounts can be preceded by a minus sign (or a plus sign, though plus is
-       the default), The sign can be written before or after a left-side  com-
-       modity symbol:
-
-              -$1
-              $-1
-
-       One  or more spaces between the sign and the number are acceptable when
-       parsing (but they won't be displayed in output):
-
-              + $1
-              $-      1
-
-       Scientific E notation is allowed:
-
-              1E-6
-              EUR 1E3
-
-   Decimal marks, digit group marks
-       A decimal mark can be written as a period or a comma:
-
-              1.23
-              1,23456780000009
-
-       In the integer part of the quantity (left of the decimal mark),  groups
-       of  digits  can  optionally  be  separated  by a "digit group mark" - a
-       space, comma, or period (different from the decimal mark):
-
-                   $1,000,000.00
-                EUR 2.000.000,00
-              INR 9,99,99,999.00
-                    1 000 000.9455
-
-       Note, a number containing a single digit group mark and no decimal mark
-       is ambiguous.  Are these digit group marks or decimal marks ?
-
-              1,000
-              1.000
-
-       If  you  don't tell it otherwise, hledger will assume both of the above
-       are decimal marks, parsing both numbers as 1.  To prevent confusion and
-       undetected  typos,  we recommend adding commodity directives at the top
-       of your journal file  to  explicitly  declare  the  decimal  mark  (and
-       optionally  a  digit  group mark) for each commodity.  Read on for more
-       about this.
-
-   Commodity
-       Amounts in hledger have both a "quantity", which is  a  signed  decimal
-       number, and a "commodity", which is a currency symbol, stock ticker, or
-       any word or phrase describing something you are tracking.
-
-       If the commodity name contains non-letters (spaces, numbers, or punctu-
-       ation),  you must always write it inside double quotes ("green apples",
-       "ABC123").
-
-       If you write just a bare number, that too will have a  commodity,  with
-       name ""; we call that the "no-symbol commodity".
-
-       Actually,  hledger  combines  these  single-commodity amounts into more
-       powerful multi-commodity amounts, which are what it works with most  of
-       the  time.   A multi-commodity amount could be, eg: 1 USD, 2 EUR, 3.456
-       TSLA.  In practice,  you  will  only  see  multi-commodity  amounts  in
-       hledger's output; you can't write them directly in the journal file.
-
-       (If  you are writing scripts or working with hledger's internals, these
-       are the Amount and MixedAmount types.)
-
-   Commodity directives
-       You can add commodity directives to the journal, preferably at the top,
-       to  declare  your  commodities and help with number parsing (see above)
-       and display (see below).  These are optional,  but  recommended.   They
-       are  described  in  more detail in JOURNAL FORMAT -> Declaring commodi-
-       ties.  Here's a quick example:
-
-              # number format and display style for $, EUR, INR and the no-symbol commodity:
-              commodity $1,000.00
-              commodity EUR 1.000,00
-              commodity INR 9,99,99,999.00
-              commodity 1 000 000.9455
-
-
-   Commodity display style
-       For the amounts in each commodity, hledger chooses a consistent display
-       style  to  use  in  most  reports.  (Exceptions: price amounts, and all
-       amounts displayed by the print command, are displayed with all of their
-       decimal digits visible.)
-
-       A commodity's display style is inferred as follows.
-
-       First,  if  a  default commodity is declared with D, this commodity and
-       its style is applied to any no-symbol amounts in the journal.
-
-       Then each commodity's style is inferred from one of the  following,  in
-       order of preference:
-
-       o The  commodity  directive for that commodity (including the no-symbol
-         commodity), if any.
-
-       o The amounts in that commodity seen  in  the  journal's  transactions.
-         (Posting amounts only; prices and periodic or auto rules are ignored,
-         currently.)
-
-       o The built-in fallback style, which looks like this: $1000.00.   (Sym-
-         bol on the left, period decimal mark, two decimal places.)
-
-       A style is inferred from journal amounts as follows:
-
-       o Use  the  general style (decimal mark, symbol placement) of the first
-         amount
-
-       o Use the first-seen digit group style (digit group mark,  digit  group
-         sizes), if any
-
-       o Use the maximum number of decimal places of all.
-
-       Transaction  price  amounts  don't  affect  the commodity display style
-       directly, but occasionally they can do so indirectly (eg when  a  post-
-       ing's  amount is inferred using a transaction price).  If you find this
-       causing problems, use a commodity directive to fix the display style.
-
-       To summarise: each commodity's amounts will be normalised  to  (a)  the
-       style  declared by a commodity directive, or (b) the style of the first
-       posting amount in the journal, with the first-seen  digit  group  style
-       and  the maximum-seen number of decimal places.  So if your reports are
-       showing amounts in a way you don't  like,  eg  with  too  many  decimal
-       places, use a commodity directive.  Some examples:
-
-              # declare euro, dollar, bitcoin and no-symbol commodities and set their
-              # input number formats and output display styles:
-              commodity EUR 1.000,
-              commodity $1000.00
-              commodity 1000.00000000 BTC
-              commodity 1 000.
-
-   Rounding
-       Amounts are stored internally as decimal numbers with up to 255 decimal
-       places, and displayed with the number of decimal  places  specified  by
-       the  commodity display style.  Note, hledger uses banker's rounding: it
-       rounds to the nearest even number, eg 0.5 displayed with  zero  decimal
-       places  is  "0").   (Guaranteed since hledger 1.17.1; in older versions
-       this could vary if hledger was built with Decimal < 0.5.1.)
-
-   Transaction prices
-       Within a transaction, you can note an amount's price in another commod-
-       ity.   This can be used to document the cost (in a purchase) or selling
-       price (in a sale).  For  example,  transaction  prices  are  useful  to
-       record  purchases  of  a foreign currency.  Note transaction prices are
-       fixed at the time of the transaction, and do not change over time.  See
-       also market prices, which represent prevailing exchange rates on a cer-
-       tain date.
-
-       There are several ways to record a transaction price:
-
-       1. Write the price per unit, as @ UNITPRICE after the amount:
-
-                  2009/1/1
-                    assets:euros     EUR100 @ $1.35  ; one hundred euros purchased at $1.35 each
-                    assets:dollars                 ; balancing amount is -$135.00
-
-       2. Write the total price, as @@ TOTALPRICE after the amount:
-
-                  2009/1/1
-                    assets:euros     EUR100 @@ $135  ; one hundred euros purchased at $135 for the lot
-                    assets:dollars
-
-       3. Specify amounts for all postings, using exactly two commodities, and
-          let hledger infer the price that balances the transaction:
-
-                  2009/1/1
-                    assets:euros     EUR100          ; one hundred euros purchased
-                    assets:dollars  $-135          ; for $135
-
-       4. Like  1, but the @ is parenthesised, i.e.  (@); this is for compati-
-          bility with Ledger journals (Virtual posting costs), and is  equiva-
-          lent to 1 in hledger.
-
-       5. Like 2, but as in 4 the @@ is parenthesised, i.e.  (@@); in hledger,
-          this is equivalent to 2.
-
-       Use the -B/--cost flag to convert amounts to their transaction  price's
-       commodity, if any.  (mnemonic: "B" is from "cost Basis", as in Ledger).
-       Eg here is how -B affects the balance report for the example above:
-
-              $ hledger bal -N --flat
-                             $-135  assets:dollars
-                              EUR100  assets:euros
-              $ hledger bal -N --flat -B
-                             $-135  assets:dollars
-                              $135  assets:euros    # <- the euros' cost
-
-       Note -B is sensitive to the order of postings when a transaction  price
-       is  inferred:  the  inferred price will be in the commodity of the last
-       amount.  So if example 3's postings are reversed, while the transaction
-       is equivalent, -B shows something different:
-
-              2009/1/1
-                assets:dollars  $-135              ; 135 dollars sold
-                assets:euros     EUR100              ; for 100 euros
-
-              $ hledger bal -N --flat -B
-                             EUR-100  assets:dollars  # <- the dollars' selling price
-                              EUR100  assets:euros
-
-   Lot prices, lot dates
-       Ledger  allows  another kind of price, lot price (four variants: {UNIT-
-       PRICE},   {{TOTALPRICE}},   {=FIXEDUNITPRICE},   {{=FIXEDTOTALPRICE}}),
-       and/or a lot date ([DATE]) to be specified.  These are normally used to
-       select a lot when selling investments.  hledger will parse  these,  for
-       compatibility  with  Ledger  journals,  but  currently ignores them.  A
-       transaction price, lot price and/or lot date may appear in  any  order,
-       after the posting amount and before the balance assertion if any.
-
-   Balance assertions
-       hledger  supports  Ledger-style  balance  assertions  in journal files.
-       These look like, for example, = EXPECTEDBALANCE following  a  posting's
-       amount.   Eg  here  we assert the expected dollar balance in accounts a
-       and b after each posting:
-
-              2013/1/1
-                a   $1  =$1
-                b       =$-1
-
-              2013/1/2
-                a   $1  =$2
-                b  $-1  =$-2
-
-       After reading a journal file, hledger will check all balance assertions
-       and  report  an error if any of them fail.  Balance assertions can pro-
-       tect you from, eg, inadvertently disrupting reconciled  balances  while
-       cleaning  up  old  entries.   You can disable them temporarily with the
-       -I/--ignore-assertions flag, which can be useful for troubleshooting or
-       for  reading Ledger files.  (Note: this flag currently does not disable
-       balance assignments, below).
-
-   Assertions and ordering
-       hledger sorts an account's postings and assertions first  by  date  and
-       then  (for postings on the same day) by parse order.  Note this is dif-
-       ferent from Ledger, which sorts assertions only by parse order.  (Also,
-       Ledger  assertions  do not see the accumulated effect of repeated post-
-       ings to the same account within a transaction.)
-
-       So, hledger balance assertions keep working if you reorder differently-
-       dated  transactions  within the journal.  But if you reorder same-dated
-       transactions or postings, assertions might break and require  updating.
-       This order dependence does bring an advantage: precise control over the
-       order of postings and assertions within a day, so you can assert intra-
-       day balances.
-
-   Assertions and included files
-       With  included  files, things are a little more complicated.  Including
-       preserves the ordering of postings and assertions.  If you have  multi-
-       ple  postings  to  an  account  on the same day, split across different
-       files, and you also want to assert the account's balance  on  the  same
-       day, you'll have to put the assertion in the right file.
-
-   Assertions and multiple -f options
-       Balance assertions don't work well across files specified with multiple
-       -f options.  Use include or concatenate the files instead.
-
-   Assertions and commodities
-       The asserted balance must be a simple single-commodity amount,  and  in
-       fact  the  assertion  checks  only  this commodity's balance within the
-       (possibly multi-commodity) account balance.   This  is  how  assertions
-       work in Ledger also.  We could call this a "partial" balance assertion.
-
-       To assert the balance of more than one commodity in an account, you can
-       write multiple postings, each asserting one commodity's balance.
-
-       You  can  make a stronger "total" balance assertion by writing a double
-       equals sign (== EXPECTEDBALANCE).  This asserts that there are no other
-       unasserted commodities in the account (or, that their balance is 0).
-
-              2013/1/1
-                a   $1
-                a    1EUR
-                b  $-1
-                c   -1EUR
-
-              2013/1/2  ; These assertions succeed
-                a    0  =  $1
-                a    0  =   1EUR
-                b    0 == $-1
-                c    0 ==  -1EUR
-
-              2013/1/3  ; This assertion fails as 'a' also contains 1EUR
-                a    0 ==  $1
-
-       It's not yet possible to make a complete assertion about a balance that
-       has multiple commodities.  One workaround is to isolate each  commodity
-       into its own subaccount:
-
-              2013/1/1
-                a:usd   $1
-                a:euro   1EUR
-                b
-
-              2013/1/2
-                a        0 ==  0
-                a:usd    0 == $1
-                a:euro   0 ==  1EUR
-
-   Assertions and prices
-       Balance  assertions  ignore  transaction prices, and should normally be
-       written without one:
-
-              2019/1/1
-                (a)     $1 @ EUR1 = $1
-
-       We do allow prices to be written there, however, and print shows  them,
-       even  though  they  don't affect whether the assertion passes or fails.
-       This is for backward compatibility (hledger's  close  command  used  to
-       generate  balance  assertions with prices), and because balance assign-
-       ments do use them (see below).
-
-   Assertions and subaccounts
-       The balance assertions above (= and ==) do not count the  balance  from
-       subaccounts;  they check the account's exclusive balance only.  You can
-       assert the balance including subaccounts by writing =* or ==*, eg:
-
-              2019/1/1
-                equity:opening balances
-                checking:a       5
-                checking:b       5
-                checking         1  ==* 11
-
-   Assertions and virtual postings
-       Balance assertions are checked against all postings, both real and vir-
-       tual.  They are not affected by the --real/-R flag or real: query.
-
-   Assertions and precision
-       Balance  assertions  compare  the exactly calculated amounts, which are
-       not always what is shown by reports.   Eg  a  commodity  directive  may
-       limit  the  display  precision, but this will not affect balance asser-
-       tions.  Balance assertion failure messages show exact amounts.
-
-   Balance assignments
-       Ledger-style balance assignments are also supported.   These  are  like
-       balance  assertions, but with no posting amount on the left side of the
-       equals sign; instead it is calculated automatically so  as  to  satisfy
-       the  assertion.   This  can be a convenience during data entry, eg when
-       setting opening balances:
-
-              ; starting a new journal, set asset account balances
-              2016/1/1 opening balances
-                assets:checking            = $409.32
-                assets:savings             = $735.24
-                assets:cash                 = $42
-                equity:opening balances
-
-       or when adjusting a balance to reality:
-
-              ; no cash left; update balance, record any untracked spending as a generic expense
-              2016/1/15
-                assets:cash    = $0
-                expenses:misc
-
-       The calculated amount depends on the account's balance in the commodity
-       at  that  point  (which depends on the previously-dated postings of the
-       commodity to that account since the last balance assertion  or  assign-
-       ment).  Note that using balance assignments makes your journal a little
-       less explicit; to know the exact amount posted, you have to run hledger
-       or do the calculations yourself, instead of just reading it.
-
-   Balance assignments and prices
-       A  transaction  price in a balance assignment will cause the calculated
-       amount to have that price attached:
-
-              2019/1/1
-                (a)             = $1 @ EUR2
-
-              $ hledger print --explicit
-              2019-01-01
-                  (a)         $1 @ EUR2 = $1 @ EUR2
-
-   Directives
-       A directive is a line in the journal beginning with a special  keyword,
-       that influences how the journal is processed.  hledger's directives are
-       based on a subset of Ledger's, but there are many differences (and also
-       some differences between hledger versions).
-
-       Directives' behaviour and interactions can get a little bit complex, so
-       here is a table summarising the  directives  and  their  effects,  with
-       links to more detailed docs.

-       direc-   which  entries  and  (when there are multiple files) which files
-       tive     are affected by a directive
-       scope
-
-       As you can see, directives vary in which journal entries and files they
-       affect,  and  whether  they  are  focussed on input (parsing) or output
-       (reports).  Some directives have multiple effects.
-
-   Directives and multiple files
-       If you use  multiple  -f/--file  options,  or  the  include  directive,
-       hledger  will  process  multiple input files.  But note that directives
-       which affect input (see above) typically last only until the end of the
-       file in which they occur.
-
-       This may seem inconvenient, but it's intentional; it makes reports sta-
-       ble and deterministic, independent of the order  of  input.   Otherwise
-       you  could see different numbers if you happened to write -f options in
-       a different order, or if you moved includes around  while  cleaning  up
-       your files.
-
-       It  can  be  surprising though; for example, it means that alias direc-
-       tives do not affect parent or sibling files (see below).
-
-   Comment blocks
-       A line containing just comment starts a commented region of  the  file,
-       and a line containing just end comment (or the end of the current file)
-       ends it.  See also comments.
-
-   Including other files
-       You can pull in the content of additional files by writing  an  include
-       directive, like this:
-
-              include FILEPATH
-
-       Only  journal files can include, and only journal, timeclock or timedot
-       files can be included (not CSV files, currently).
-
-       If the file path does not begin with a slash, it  is  relative  to  the
-       current file's folder.
-
-       A tilde means home directory, eg: include ~/main.journal.
-
-       The path may contain glob patterns to match multiple files, eg: include
-       *.journal.
-
-       There is limited support for recursive wildcards:  **/  (the  slash  is
-       required)  matches 0 or more subdirectories.  It's not super convenient
-       since you have to avoid include cycles and including  directories,  but
-       this can be done, eg: include */**/*.journal.
-
-       The path may also be prefixed to force a specific file format, overrid-
-       ing the file extension (as described  in  hledger.1  ->  Input  files):
-       include timedot:~/notes/2020*.md.
-
-   Default year
-       You  can set a default year to be used for subsequent dates which don't
-       specify a year.  This is a line beginning with Y followed by the  year.
-       Eg:
-
-              Y2009  ; set default year to 2009
-
-              12/15  ; equivalent to 2009/12/15
-                expenses  1
-                assets
-
-              Y2010  ; change default year to 2010
-
-              2009/1/30  ; specifies the year, not affected
-                expenses  1
-                assets
-
-              1/31   ; equivalent to 2010/1/31
-                expenses  1
-                assets
-
-   Declaring payees
-       The  payee  directive  can  be  used to declare a limited set of payees
-       which may appear in transaction descriptions.  The "payees" check  will
-       report  an error if any transaction refers to a payee that has not been
-       declared.  Eg:
-
-              payee Whole Foods
-
-   Declaring commodities
-       You can use commodity directives to declare your commodities.  In  fact
-       the commodity directive performs several functions at once:
-
-       1. It  declares commodities which may be used in the journal.  This can
-          optionally be enforced, providing useful error checking.   (Cf  Com-
-          modity error checking)
-
-       2. It  declares  which  decimal  mark  character  (period or comma), to
-          expect when parsing input -  useful  to  disambiguate  international
-          number  formats in your data.  Without this, hledger will parse both
-          1,000 and 1.000 as 1.  (Cf Amounts)
-
-       3. It declares how to render the commodity's  amounts  when  displaying
-          output - the decimal mark, any digit group marks, the number of dec-
-          imal places, symbol placement and  so  on.   (Cf  Commodity  display
-          style)
-
-       You  will  run  into one of the problems solved by commodity directives
-       sooner or later, so we recommend using them, for robust and predictable
-       parsing and display.
-
-       Generally  you  should  put them at the top of your journal file (since
-       for function 2, they affect only following amounts, cf #793).
-
-       A commodity directive is just the word commodity followed by  a  sample
-       amount, like this:
-
-              ;commodity SAMPLEAMOUNT
-
-              commodity $1000.00
-              commodity 1,000.0000 AAAA  ; optional same-line comment
-
-       It  may also be written on multiple lines, and use the format subdirec-
-       tive, as in Ledger.  Note in this case  the  commodity  symbol  appears
-       twice; it must be the same in both places:
-
-              ;commodity SYMBOL
-              ;  format SAMPLEAMOUNT
-
-              ; display indian rupees with currency name on the left,
-              ; thousands, lakhs and crores comma-separated,
-              ; period as decimal point, and two decimal places.
-              commodity INR
-                format INR 1,00,00,000.00
-
-       Remember  that  if  the  commodity  symbol contains spaces, numbers, or
-       punctuation, it must be enclosed in double quotes (cf Commodity).
-
-       The amount's quantity does not matter; only the format is  significant.
-       It  must include a decimal mark - either a period or a comma - followed
-       by 0 or more decimal digits.
-
-       A few more examples:
-
-              # number formats for $, EUR, INR and the no-symbol commodity:
-              commodity $1,000.00
-              commodity EUR 1.000,00
-              commodity INR 9,99,99,999.0
-              commodity 1 000 000.
-
-       Note hledger normally uses banker's rounding,  so  0.5  displayed  with
-       zero decimal digits is "0".  (More at Commodity display style.)
-
-   Commodity error checking
-       In  strict mode, enabled with the -s/--strict flag, hledger will report
-       an error if a commodity symbol is used that has not been declared by  a
-       commodity  directive.   This works similarly to account error checking,
-       see the notes there for more details.
-
-   Default commodity
-       The D directive sets a default commodity, to be used for any subsequent
-       commodityless  amounts (ie, plain numbers) seen while parsing the jour-
-       nal.  This effect lasts until the next D directive, or the end  of  the
-       journal.
-
-       For  compatibility/historical  reasons,  D  also  acts like a commodity
-       directive (setting the commodity's decimal mark for parsing and display
-       style for output).
-
-       As  with  commodity,  the  amount  must  include a decimal mark (either
-       period or comma).  If both commodity and D directives are used for  the
-       same commodity, the commodity style takes precedence.
-
-       The syntax is D AMOUNT.  Eg:
-
-              ; commodity-less amounts should be treated as dollars
-              ; (and displayed with the dollar sign on the left, thousands separators and two decimal places)
-              D $1,000.00
-
-              1/1
-                a     5  ; <- commodity-less amount, parsed as $5 and displayed as $5.00
-                b
-
-   Declaring market prices
-       The  P  directive  declares  a  market price, which is an exchange rate
-       between two commodities on a certain date.  (In Ledger, they are called
-       "historical  prices".)  These are often obtained from a stock exchange,
-       cryptocurrency exchange, or the foreign exchange market.
-
-       The format is:
-
-              P DATE COMMODITY1SYMBOL COMMODITY2AMOUNT
-
-       DATE is a simple date, COMMODITY1SYMBOL is the symbol of the  commodity
-       being  priced, and COMMODITY2AMOUNT is the amount (symbol and quantity)
-       of commodity 2 that one unit of commodity 1  is  worth  on  this  date.
-       Examples:
-
-              # one euro was worth $1.35 from 2009-01-01 onward:
-              P 2009-01-01 EUR $1.35
-
-              # and $1.40 from 2010-01-01 onward:
-              P 2010-01-01 EUR $1.40
-
-       The  -V,  -X  and  --value flags use these market prices to show amount
-       values in another commodity.  See Valuation.
-
-   Declaring accounts
-       account directives can be used to declare accounts (ie, the places that
-       amounts  are transferred from and to).  Though not required, these dec-
-       larations can provide several benefits:
-
-       o They can document your intended chart of accounts, providing a refer-
-         ence.
-
-       o They  can  help  hledger know your accounts' types (asset, liability,
-         equity, revenue, expense), useful for reports like  balancesheet  and
-         incomestatement.
-
-       o They  control  account  display order in reports, allowing non-alpha-
-         betic sorting (eg Revenues to appear above Expenses).
-
-       o They can store extra information  about  accounts  (account  numbers,
-         notes, etc.)
-
-       o They  help  with account name completion in the add command, hledger-
-         iadd, hledger-web, ledger-mode etc.
-
-       o In strict mode, they restrict which accounts  may  be  posted  to  by
-         transactions, which helps detect typos.
-
-       The  simplest form is just the word account followed by a hledger-style
-       account name, eg this account directive declares the assets:bank:check-
-       ing account:
-
-              account assets:bank:checking
-
-   Account error checking
-       By  default, accounts come into existence when a transaction references
-       them by name.  This is convenient, but it means hledger can't warn  you
-       when you mis-spell an account name in the journal.  Usually you'll find
-       the error later, as an extra account in balance reports, or  an  incor-
-       rect balance when reconciling.
-
-       In  strict mode, enabled with the -s/--strict flag, hledger will report
-       an error if any transaction uses an account  name  that  has  not  been
-       declared by an account directive.  Some notes:
-
-       o The  declaration is case-sensitive; transactions must use the correct
-         account name capitalisation.
-
-       o The account directive's scope is "whole file and below"  (see  direc-
-         tives).  This means it affects all of the current file, and any files
-         it includes, but not  parent  or  sibling  files.   The  position  of
-         account directives within the file does not matter, though it's usual
-         to put them at the top.
-
-       o Accounts can only be declared  in  journal  files  (but  will  affect
-         included files in other formats).
-
-       o It's  currently  not  possible  to declare "all possible subaccounts"
-         with a wildcard; every account posted to must be declared.
-
-   Account comments
-       Comments, beginning with a semicolon, can be added:
-
-       o on the same line, after two or more spaces (because ; is  allowed  in
-         account names)
-
-       o on the next lines, indented
-
-       An example of both:
-
-              account assets:bank:checking  ; same-line comment, note 2+ spaces before ;
-                ; next-line comment
-                ; another with tag, acctno:12345 (not used yet)
-
-       Same-line comments are not supported by Ledger, or hledger <1.13.
-
-   Account subdirectives
-       We  also  allow  (and ignore) Ledger-style indented subdirectives, just
-       for compatibility.:
-
-              account assets:bank:checking
-                format blah blah  ; <- subdirective, ignored
-
-       Here is the full syntax of account directives:
-
-              account ACCTNAME  [ACCTTYPE] [;COMMENT]
-                [;COMMENTS]
-                [LEDGER-STYLE SUBDIRECTIVES, IGNORED]
-
-   Account types
-       hledger recognises five main types of  account,  corresponding  to  the
-       account classes in the accounting equation:
-
-       Asset, Liability, Equity, Revenue, Expense.
-
-       These account types are important for controlling which accounts appear
-       in the balancesheet, balancesheetequity, incomestatement  reports  (and
-       probably for other things in future).
-
-       Additionally,  we  recognise the Cash type, which is also an Asset, and
-       which causes accounts to appear in the cashflow report.   ("Cash"  here
-       means  liquid assets, eg bank balances but typically not investments or
-       receivables.)
-
-   Declaring account types
-       Generally, to make these reports work you should declare your top-level
-       accounts and their types, using account directives with type: tags.
-
-       The  tag's  value  should be one of: Asset, Liability, Equity, Revenue,
-       Expense, Cash, A, L, E, R, X, C (all case insensitive).   The  type  is
-       inherited  by  all subaccounts except where they override it.  Here's a
-       complete example:
-
-              account assets       ; type: Asset
-              account assets:bank  ; type: Cash
-              account assets:cash  ; type: Cash
-              account liabilities  ; type: Liability
-              account equity       ; type: Equity
-              account revenues     ; type: Revenue
-              account expenses     ; type: Expense
-
-   Auto-detected account types
-       If you happen to use common english top-level account  names,  you  may
-       not  need  to declare account types, as they will be detected automati-
-       cally using the following rules:
-
-               If account's name matches this regular expression:                 | its type is:
-              ------------------------------------------------------------------- | ------------
-               ^assets?(:|$)                                                      |
-                 and does not contain regexp (investment|receivable|:A/R|:fixed)  | Cash
-                 otherwise                                                        | Asset
-               ^(debts?|liabilit(y|ies))(:|$)                                     | Liability
-               ^equity(:|$)                                                       | Equity
-               ^(income|revenue)s?(:|$)                                           | Revenue
-               ^expenses?(:|$)                                                    | Expense
-
-       Even so, explicit declarations may be a good idea, for clarity and pre-
-       dictability.
-
-   Interference from auto-detected account types
-       If you assign any account type, it's a good idea to assign all of them,
-       to prevent any confusion from mixing declared and auto-detected  types.
-       Although  it's unlikely to happen in real life, here's an example: with
-       the following journal, balancesheetequity shows "liabilities"  in  both
-       Liabilities   and   Equity  sections.   Declaring  another  account  as
-       type:Liability would fix it:
-
-              account liabilities  ; type:Equity
-
-              2020-01-01
-                assets        1
-                liabilities   1
-                equity       -2
-
-   Old account type syntax
-       In some hledger journals you might instead see  this  old  syntax  (the
-       letters  ALERX, separated from the account name by two or more spaces);
-       this is deprecated and may be removed soon:
-
-              account assets       A
-              account liabilities  L
-              account equity       E
-              account revenues     R
-              account expenses     X
-
-   Account display order
-       Account directives also set the order in which accounts are  displayed,
-       eg  in  reports,  the  hledger-ui  accounts screen, and the hledger-web
-       sidebar.  By default accounts are listed in alphabetical order.  But if
-       you have these account directives in the journal:
-
-              account assets
-              account liabilities
-              account equity
-              account revenues
-              account expenses
-
-       you'll see those accounts displayed in declaration order, not alphabet-
-       ically:
-
-              $ hledger accounts -1
-              assets
-              liabilities
-              equity
-              revenues
-              expenses
-
-       Undeclared accounts, if any, are displayed last, in alphabetical order.
-
-       Note  that  sorting  is  done at each level of the account tree (within
-       each group of sibling accounts under the same parent).  And  currently,
-       this directive:
-
-              account other:zoo
-
-       would  influence the position of zoo among other's subaccounts, but not
-       the position of other among the top-level accounts.  This means:
-
-       o you will sometimes declare parent accounts (eg account  other  above)
-         that  you  don't  intend  to post to, just to customize their display
-         order
-
-       o sibling accounts stay together (you couldn't display x:y  in  between
-         a:b and a:c).
-
-   Rewriting accounts
-       You can define account alias rules which rewrite your account names, or
-       parts of them, before generating reports.  This can be useful for:
-
-       o expanding shorthand account names to their full form, allowing easier
-         data entry and a less verbose journal
-
-       o adapting old journals to your current chart of accounts
-
-       o experimenting with new account organisations, like a new hierarchy or
-         combining two accounts into one
-
-       o customising reports
-
-       Account aliases also rewrite account names in account directives.  They
-       do  not  affect account names being entered via hledger add or hledger-
-       web.
-
-       See also Rewrite account names.
-
-   Basic aliases
-       To set an account alias, use the alias directive in your journal  file.
-       This  affects all subsequent journal entries in the current file or its
-       included files (but note: not sibling or  parent  files).   The  spaces
-       around the = are optional:
-
-              alias OLD = NEW
-
-       Or, you can use the --alias 'OLD=NEW' option on the command line.  This
-       affects all entries.  It's useful for trying out aliases interactively.
-
-       OLD  and  NEW  are  case  sensitive  full  account names.  hledger will
-       replace any occurrence of the old account name with the new one.   Sub-
-       accounts are also affected.  Eg:
-
-              alias checking = assets:bank:wells fargo:checking
-              ; rewrites "checking" to "assets:bank:wells fargo:checking", or "checking:a" to "assets:bank:wells fargo:checking:a"
-
-   Regex aliases
-       There  is  also a more powerful variant that uses a regular expression,
-       indicated by the forward slashes:
-
-              alias /REGEX/ = REPLACEMENT
-
-       or --alias '/REGEX/=REPLACEMENT'.
-
-       REGEX is a case-insensitive regular expression.   Anywhere  it  matches
-       inside  an  account name, the matched part will be replaced by REPLACE-
-       MENT.  If REGEX contains parenthesised match groups, these can be  ref-
-       erenced by the usual numeric backreferences in REPLACEMENT.  Eg:
-
-              alias /^(.+):bank:([^:]+):(.*)/ = \1:\2 \3
-              ; rewrites "assets:bank:wells fargo:checking" to  "assets:wells fargo checking"
-
-       Also  note that REPLACEMENT continues to the end of line (or on command
-       line, to end of option argument), so it  can  contain  trailing  white-
-       space.
-
-   Combining aliases
-       You  can  define  as many aliases as you like, using journal directives
-       and/or command line options.
-
-       Recursive aliases - where an account name is rewritten  by  one  alias,
-       then  by  another  alias, and so on - are allowed.  Each alias sees the
-       effect of previously applied aliases.
-
-       In such cases it can be important to understand which aliases  will  be
-       applied  and  in  which order.  For (each account name in) each journal
-       entry, we apply:
-
-       1. alias directives preceding the journal entry, most  recently  parsed
-          first (ie, reading upward from the journal entry, bottom to top)
-
-       2. --alias  options,  in  the  order  they appeared on the command line
-          (left to right).
-
-       In other words, for (an account name in) a given journal entry:
-
-       o the nearest alias declaration before/above the entry is applied first
-
-       o the next alias before/above that will be be applied next, and so on
-
-       o aliases defined after/below the entry do not affect it.
-
-       This  gives nearby aliases precedence over distant ones, and helps pro-
-       vide semantic stability - aliases will keep working the same way  inde-
-       pendent of which files are being read and in which order.
-
-       In  case  of  trouble,  adding  --debug=6 to the command line will show
-       which aliases are being applied when.
-
-   Aliases and multiple files
-       As explained at Directives and multiple files, alias directives do  not
-       affect parent or sibling files.  Eg in this command,
-
-              hledger -f a.aliases -f b.journal
-
-       account  aliases  defined  in  a.aliases  will  not  affect  b.journal.
-       Including the aliases doesn't work either:
-
-              include a.aliases
-
-              2020-01-01  ; not affected by a.aliases
-                foo  1
-                bar
-
-       This means that account aliases should usually be declared at the start
-       of your top-most file, like this:
-
-              alias foo=Foo
-              alias bar=Bar
-
-              2020-01-01  ; affected by aliases above
-                foo  1
-                bar
-
-              include c.journal  ; also affected
-
-   end aliases
-       You  can  clear  (forget)  all  currently  defined aliases with the end
-       aliases directive:
-
-              end aliases
-
-   Default parent account
-       You can specify a  parent  account  which  will  be  prepended  to  all
-       accounts  within  a  section of the journal.  Use the apply account and
-       end apply account directives like so:
-
-              apply account home
-
-              2010/1/1
-                  food    $10
-                  cash
-
-              end apply account
-
-       which is equivalent to:
-
-              2010/01/01
-                  home:food           $10
-                  home:cash          $-10
-
-       If end apply account is omitted, the effect lasts to  the  end  of  the
-       file.  Included files are also affected, eg:
-
-              apply account business
-              include biz.journal
-              end apply account
-              apply account personal
-              include personal.journal
-
-       Prior  to  hledger 1.0, legacy account and end spellings were also sup-
-       ported.
-
-       A default parent account also affects account directives.  It does  not
-       affect  account names being entered via hledger add or hledger-web.  If
-       account aliases are present, they are applied after the default  parent
-       account.
-
-   Periodic transactions
-       Periodic  transaction  rules  describe  transactions  that recur.  They
-       allow hledger to generate temporary future transactions  to  help  with
-       forecasting,  so  you  don't have to write out each one in the journal,
-       and it's easy to try out different forecasts.
-
-       Periodic transactions can be a little tricky, so before you  use  them,
-       read this whole section - or at least these tips:
-
-       1. Two  spaces  accidentally  added or omitted will cause you trouble -
-          read about this below.
-
-       2. For troubleshooting, show the generated  transactions  with  hledger
-          print   --forecast  tag:generated  or  hledger  register  --forecast
-          tag:generated.
-
-       3. Forecasted transactions will begin only  after  the  last  non-fore-
-          casted transaction's date.
-
-       4. Forecasted  transactions  will  end 6 months from today, by default.
-          See below for the exact start/end rules.
-
-       5. period  expressions  can  be  tricky.   Their  documentation   needs
-          improvement, but is worth studying.
-
-       6. Some  period  expressions  with a repeating interval must begin on a
-          natural boundary of that interval.  Eg in  weekly  from  DATE,  DATE
-          must  be a monday.  ~ weekly from 2019/10/1 (a tuesday) will give an
-          error.
-
-       7. Other period expressions with an interval are automatically expanded
-          to  cover a whole number of that interval.  (This is done to improve
-          reports, but it also affects periodic transactions.  Yes, it's a bit
-          inconsistent  with  the  above.)  Eg: ~ every 10th day of month from
-          2020/01, which is equivalent to ~  every  10th  day  of  month  from
-          2020/01/01, will be adjusted to start on 2019/12/10.
-
-       Periodic transaction rules also have a second meaning: they are used to
-       define budget goals, shown in budget reports.
-
-   Periodic rule syntax
-       A periodic transaction rule looks like a normal journal entry, with the
-       date replaced by a tilde (~) followed by a period expression (mnemonic:
-       ~ looks like a recurring sine wave.):
-
-              ~ monthly
-                  expenses:rent          $2000
-                  assets:bank:checking
-
-       There is an additional constraint on the period expression:  the  start
-       date  must fall on a natural boundary of the interval.  Eg monthly from
-       2018/1/1 is valid, but monthly from 2018/1/15 is not.
-
-       Partial or relative dates (M/D, D, tomorrow, last week) in  the  period
-       expression  can work (useful or not).  They will be relative to today's
-       date, unless a Y default year directive is in  effect,  in  which  case
-       they will be relative to Y/1/1.
-
-   Two spaces between period expression and description!
-       If  the  period  expression  is  followed by a transaction description,
-       these must be separated by two or more spaces.  This helps hledger know
-       where the period expression ends, so that descriptions can not acciden-
-       tally alter their meaning, as in this example:
-
-              ; 2 or more spaces needed here, so the period is not understood as "every 2 months in 2020"
-              ;               ||
-              ;               vv
-              ~ every 2 months  in 2020, we will review
-                  assets:bank:checking   $1500
-                  income:acme inc
-
-       So,
-
-       o Do write two spaces between your period expression and your  transac-
-         tion description, if any.
-
-       o Don't  accidentally  write  two  spaces  in the middle of your period
-         expression.
-
-   Forecasting with periodic transactions
-       The --forecast flag activates any periodic  transaction  rules  in  the
-       journal.   They  will  generate temporary recurring transactions, which
-       are not saved in the journal,  but  will  appear  in  all  reports  (eg
-       print).  This can be useful for estimating balances into the future, or
-       experimenting with different scenarios.  Or, it can be used as  a  data
-       entry aid: describe recurring transactions, and every so often copy the
-       output of print --forecast into the journal.
-
-       These transactions will have an extra  tag  indicating  which  periodic
-       rule generated them: generated-transaction:~ PERIODICEXPR.  And a simi-
-       lar, hidden tag (beginning with  an  underscore)  which,  because  it's
-       never  displayed  by print, can be used to match transactions generated
-       "just now": _generated-transaction:~ PERIODICEXPR.
-
-       Periodic transactions are generated within some  forecast  period.   By
-       default, this
-
-       o begins on the later of
-
-         o the report start date if specified with -b/-p/date:
-
-         o the  day  after the latest normal (non-periodic) transaction in the
-           journal, or today if there are no normal transactions.
-
-       o ends on the report end date  if  specified  with  -e/-p/date:,  or  6
-         months (180 days) from today.
-
-       This  means that periodic transactions will begin only after the latest
-       recorded transaction.  And a recorded transaction dated in  the  future
-       can  prevent  generation of periodic transactions.  (You can avoid that
-       by writing the future transaction as a one-time periodic rule instead -
-       put tilde before the date, eg ~ YYYY-MM-DD ...).
-
-       Or, you can set your own arbitrary "forecast period", which can overlap
-       recorded transactions, and need not be in the future, by  providing  an
-       option  argument,  like --forecast=PERIODEXPR.  Note the equals sign is
-       required, a space won't work.  PERIODEXPR is a period expression, which
-       can  specify  the start date, end date, or both, like in a date: query.
-       (See also hledger.1 ->  Report  start  &  end  date).   Some  examples:
-       --forecast=202001-202004, --forecast=jan-, --forecast=2020.
-
-   Budgeting with periodic transactions
-       With  the  --budget  flag,  currently supported by the balance command,
-       each periodic transaction rule declares recurring budget goals for  the
-       specified  accounts.   Eg  the  first  example above declares a goal of
-       spending $2000 on rent (and also,  a  goal  of  depositing  $2000  into
-       checking)  every  month.  Goals and actual performance can then be com-
-       pared in budget reports.
-
-       See also: Budgeting and Forecasting.

-
-   Auto postings
-       "Automated postings" or "auto postings" are extra  postings  which  get
-       added  automatically  to  transactions  which  match  certain  queries,
-       defined by "auto posting rules", when you use the --auto flag.
-
-       An auto posting rule looks a bit like a transaction:
-
-              = QUERY
-                  ACCOUNT  AMOUNT
-                  ...
-                  ACCOUNT  [AMOUNT]
-
-       except the first line is an equals sign (mnemonic:  =  suggests  match-
-       ing),  followed  by a query (which matches existing postings), and each
-       "posting" line describes a posting to be  generated,  and  the  posting
-       amounts can be:
-
-       o a  normal  amount  with a commodity symbol, eg $2.  This will be used
-         as-is.
-
-       o a number, eg 2.  The commodity symbol (if any) from the matched post-
-         ing will be added to this.
-
-       o a  numeric  multiplier,  eg  *2 (a star followed by a number N).  The
-         matched posting's amount (and total price, if any) will be multiplied
-         by N.
-
-       o a  multiplier  with a commodity symbol, eg *$2 (a star, number N, and
-         symbol S).  The matched posting's amount will be multiplied by N, and
-         its commodity symbol will be replaced with S.
-
-       Any  query  term containing spaces must be enclosed in single or double
-       quotes, as on the command line.  Eg, note the quotes around the  second
-       query term below:
-
-              = expenses:groceries 'expenses:dining out'
-                  (budget:funds:dining out)                 *-1
-
-       Some examples:
-
-              ; every time I buy food, schedule a dollar donation
-              = expenses:food
-                  (liabilities:charity)   $-1
-
-              ; when I buy a gift, also deduct that amount from a budget envelope subaccount
-              = expenses:gifts
-                  assets:checking:gifts  *-1
-                  assets:checking         *1
-
-              2017/12/1
-                expenses:food    $10
-                assets:checking
-
-              2017/12/14
-                expenses:gifts   $20
-                assets:checking
-
-              $ hledger print --auto
-              2017-12-01
-                  expenses:food              $10
-                  assets:checking
-                  (liabilities:charity)      $-1
-
-              2017-12-14
-                  expenses:gifts             $20
-                  assets:checking
-                  assets:checking:gifts     -$20
-                  assets:checking            $20
-
-   Auto postings and multiple files
-       An auto posting rule can affect any transaction in the current file, or
-       in any parent file or child file.  Note, currently it will  not  affect
-       sibling files (when multiple -f/--file are used - see #1212).
-
-   Auto postings and dates
-       A  posting  date (or secondary date) in the matched posting, or (taking
-       precedence) a posting date in the auto posting rule itself,  will  also
-       be used in the generated posting.
-
-   Auto postings and transaction balancing / inferred amounts / balance asser-
-       tions
-       Currently, auto postings are added:
-
-       o after missing amounts are inferred, and transactions are checked  for
-         balancedness,
-
-       o but before balance assertions are checked.
-
-       Note  this  means that journal entries must be balanced both before and
-       after auto postings are added.  This changed in hledger 1.12+; see #893
-       for background.
-
-   Auto posting tags
-       Automated postings will have some extra tags:
-
-       o generated-posting:= QUERY - shows this was generated by an auto post-
-         ing rule, and the query
-
-       o _generated-posting:= QUERY - a hidden tag, which does not  appear  in
-         hledger's output.  This can be used to match postings generated "just
-         now", rather than generated in the past and saved to the journal.
-
-       Also, any transaction that has been changed by auto posting rules  will
-       have these tags added:
-
-       o modified: - this transaction was modified
-
-       o _modified: - a hidden tag not appearing in the comment; this transac-
-         tion was modified "just now".
-
-CSV FORMAT
-       How hledger reads CSV data, and the CSV rules file format.
-
-       hledger can read CSV files (Character Separated Value - usually  comma,
-       semicolon,  or  tab)  containing  dated records as if they were journal
-       files, automatically converting each CSV record into a transaction.
-
-       (To learn about writing CSV, see CSV output.)
-
-       We describe each CSV file's format with a corresponding rules file.  By
-       default  this is named like the CSV file with a .rules extension added.
-       Eg when reading FILE.csv, hledger also looks for FILE.csv.rules in  the
-       same  directory  as  FILE.csv.   You can specify a different rules file
-       with the --rules-file option.  If a rules file is  not  found,  hledger
-       will create a sample rules file, which you'll need to adjust.
-
-       This  file  contains rules describing the CSV data (header line, fields
-       layout, date format etc.), and how to construct hledger journal entries
-       (transactions) from it.  Often there will also be a list of conditional
-       rules  for  categorising  transactions  based  on  their  descriptions.
-       Here's  an  overview  of  the CSV rules; these are described more fully
-       below, after the examples:
-
-
-       skip                         skip one or more header lines or matched CSV
-                                    records
-
-
-       fields list                  name  CSV  fields,  assign  them  to hledger
-                                    fields
-       field assignment             assign a value to one  hledger  field,  with
-                                    interpolation
-       Field names                  hledger field names, used in the fields list
-                                    and field assignments
-       separator                    a custom field separator
-       if block                     apply some rules to CSV records  matched  by
-                                    patterns
-       if table                     apply  some  rules to CSV records matched by
-                                    patterns, alternate syntax
-       end                          skip the remaining CSV records
-       date-format                  how to parse dates in CSV records
-       decimal-mark                 the decimal mark used  in  CSV  amounts,  if
-                                    ambiguous
-       newest-first                 disambiguate  record order when there's only
-                                    one date
-       include                      inline another CSV rules file
-       balance-type                 choose which type of balance assignments  to
-                                    use
-
-       Note,  for best error messages when reading CSV files, use a .csv, .tsv
-       or .ssv file extension or file prefix - see File Extension below.
-
-       There's an introductory Convert CSV files tutorial on hledger.org.
-
-   Examples
-       Here are some sample hledger CSV rules files.  See also the  full  col-
-       lection at:
-       https://github.com/simonmichael/hledger/tree/master/examples/csv
-
-   Basic
-       At  minimum,  the  rules file must identify the date and amount fields,
-       and often it also specifies the date format and how many  header  lines
-       there are.  Here's a simple CSV file and a rules file for it:
-
-              Date, Description, Id, Amount
-              12/11/2019, Foo, 123, 10.23
-
-              # basic.csv.rules
-              skip         1
-              fields       date, description, _, amount
-              date-format  %d/%m/%Y
-
-              $ hledger print -f basic.csv
-              2019-11-12 Foo
-                  expenses:unknown           10.23
-                  income:unknown            -10.23
-
-       Default account names are chosen, since we didn't set them.
-
-   Bank of Ireland
-       Here's  a  CSV with two amount fields (Debit and Credit), and a balance
-       field, which we can use to add balance assertions, which is not  neces-
-       sary but provides extra error checking:
-
-              Date,Details,Debit,Credit,Balance
-              07/12/2012,LODGMENT       529898,,10.0,131.21

-              # bankofireland-checking.csv.rules
-
-              # skip the header line

-              # name the csv fields, and assign some of them as journal entry fields
-              fields  date, description, amount-out, amount-in, balance
-
-              # We generate balance assertions by assigning to "balance"
-              # above, but you may sometimes need to remove these because:
-              #
-              # - the CSV balance differs from the true balance,
-              #   by up to 0.0000000000005 in my experience
-              #
-              # - it is sometimes calculated based on non-chronological ordering,
-              #   eg when multiple transactions clear on the same day
-
-              # date is in UK/Ireland format
-              date-format  %d/%m/%Y
-

-                  expenses:unknown                  EUR5.0
-
-       The  balance assertions don't raise an error above, because we're read-
-       ing directly from CSV, but they will be checked if  these  entries  are
-       imported into a journal file.

-       ate a third posting if there's a fee.  (In practice you'd probably  get
-       this data from your bank instead, but it's an example.)

-
-   CSV rules
-       The following kinds of rule can appear in the rules file, in any order.
-       Blank lines and lines beginning with # or ; are ignored.
-
-   skip
-              skip N
-
-       The  word  "skip"  followed by a number (or no number, meaning 1) tells
-       hledger to ignore this many non-empty lines  preceding  the  CSV  data.
-       (Empty/blank  lines  are skipped automatically.) You'll need this when-
-       ever your CSV data contains header lines.
-
-       It also has a second purpose: it can be used inside if blocks to ignore
-       certain CSV records (described below).
-
-   fields list
-              fields FIELDNAME1, FIELDNAME2, ...
-
-       A  fields  list  (the  word  "fields" followed by comma-separated field
-       names) is the quick way to assign CSV field values to  hledger  fields.
-       (The  other  way  is  field assignments, see below.) A fields list does
-       does two things:
-
-       1. It names the CSV fields.  This is optional, but  can  be  convenient
-          later for interpolating them.
-
-       2. Whenever  you use a standard hledger field name (defined below), the
-          CSV value is assigned to that part of the hledger transaction.
-
-       Here's an example that says "use the 1st, 2nd and  4th  fields  as  the
-       transaction's  date,  description  and amount; name the last two fields
-       for later reference; and ignore the others":
-
-              fields date, description, , amount, , , somefield, anotherfield
-
-       Tips:
-
-       o The fields list always use commas, even if your CSV data uses another
-         separator character.
-
-       o Currently  there  must  be  least two items in the list (at least one
-         comma).
-
-       o Field names may not contain spaces.  Spaces before/after field  names
-         are optional.
-
-       o If  the  CSV contains column headings, it's a good idea to use these,
-         suitably modified, as the basis for your field names (eg lower-cased,
-         with underscores instead of spaces).
-
-       o If  some  heading  names match standard hledger fields, but you don't
-         want to set the hledger fields directly, alter  those  names,  eg  by
-         appending an underscore.
-
-       o Fields you don't care about can be given a dummy name (eg: _ ), or no
-         name.
-
-   field assignment
-              HLEDGERFIELDNAME FIELDVALUE
-
-       Field assignments are the more flexible way to  assign  CSV  values  to
-       hledger fields.  They can be used instead of or in addition to a fields
-       list (see above).
-
-       To assign a value to a hledger field, write the field name (any of  the
-       standard  hledger  field/pseudo-field  names,  defined below), a space,
-       followed by a text value on the same line.  This text value may  inter-
-       polate  CSV  fields,  referenced  by  their 1-based position in the CSV
-       record (%N), or by the name they were given in the fields  list  (%CSV-
-       FIELDNAME).
-
-       Some examples:
-
-              # set the amount to the 4th CSV field, with " USD" appended
-              amount %4 USD
-
-              # combine three fields to make a comment, containing note: and date: tags
-              comment note: %somefield - %anotherfield, date: %1
-
-       Tips:
-
-       o Interpolation  strips  outer  whitespace  (so  a CSV value like " 1 "
-         becomes 1 when interpolated) (#1051).
-
-       o See also Tips below.
-
-   Field names
-       Here are the standard hledger field (and pseudo-field) names, which you
-       can  use in a fields list and in field assignments.  For more about the
-       transaction parts they refer to, see Transactions.
-
-   date field
-       Assigning to date sets the transaction date.
-
-   date2 field
-       date2 sets the transaction's secondary date, if any.
-
-   status field
-       status sets the transaction's status, if any.
-
-   code field
-       code sets the transaction's code, if any.
-
-   description field
-       description sets the transaction's description, if any.
-
-   comment field
-       comment sets the transaction's comment, if any.
-
-       commentN, where N is a number, sets the Nth posting's comment.
-
-       Tips: - Only single-line comments can be assigned.  - Comments can con-
-       tain tags, as usual.
-
-   account field
-       Assigning to accountN, where N is 1 to 99, sets the account name of the
-       Nth posting, and causes that posting to be generated.
-
-       Most often there are two postings, so you'll want to set  account1  and
-       account2.   Typically  account1 is associated with the CSV file, and is
-       set once with a top-level assignment, while account2 is  set  based  on
-       each transaction's description, and in conditional blocks.
-
-       If  a  posting's  account name is left unset but its amount is set (see
-       below), a default account name will be chosen (like  "expenses:unknown"
-       or "income:unknown").
-
-   amount field
-       amountN  sets the amount of the Nth posting, and causes that posting to
-       be generated.  By assigning to amount1, amount2,  ...   etc.   you  can
-       generate up to 99 postings.
-
-       amountN-in  and  amountN-out can be used instead, if the CSV uses sepa-
-       rate fields for debits and credits  (inflows  and  outflows).   hledger
-       assumes  both  of these CSV fields are unsigned, and will automatically
-       negate the "-out" value.  If they are  signed,  see  "Setting  amounts"
-       below.
-
-       amount,  or  amount-in  and  amount-out are a legacy mode, to keep pre-
-       hledger-1.17 CSV rules files working (and for occasional  convenience).
-       They  are  suitable  only  for  two-posting transactions; they set both
-       posting 1's and  posting  2's  amount.   Posting  2's  amount  will  be
-       negated, and also converted to cost if there's a transaction price.
-
-       If you have an existing rules file using the unnumbered form, you might
-       want to use the numbered form in certain  conditional  blocks,  without
-       having  to  update  and  retest all the old rules.  To facilitate this,
-       posting   1   ignores    amount/amount-in/amount-out    if    any    of
-       amount1/amount1-in/amount1-out are assigned, and posting 2 ignores them
-       if any of amount2/amount2-in/amount2-out are  assigned,  avoiding  con-
-       flicts.
-
-   currency field
-       currency  sets  a  currency  symbol,  to  be prepended to all postings'
-       amounts.  You can use this if the CSV amounts do not  have  a  currency
-       symbol, eg if it is in a separate column.
-
-       currencyN  prepends a currency symbol to just the Nth posting's amount.
-
-   balance field
-       balanceN sets a balance assertion amount (or if the posting  amount  is
-       left empty, a balance assignment) on posting N.
-
-       balance is a compatibility spelling for hledger <1.17; it is equivalent
-       to balance1.
-
-       You can adjust the type of assertion/assignment with  the  balance-type
-       rule (see below).
-
-       See Tips below for more about setting amounts and currency.
-
-   separator
-       You  can  use the separator rule to read other kinds of character-sepa-
-       rated data.  The argument is any single  separator  character,  or  the
-       words  tab or space (case insensitive).  Eg, for comma-separated values
-       (CSV):
-
-              separator ,
-
-       or for semicolon-separated values (SSV):
-
-              separator ;
-
-       or for tab-separated values (TSV):
-
-              separator TAB
-
-       If the input file has a .csv, .ssv or .tsv file extension (or  a  csv:,
-       ssv:, tsv: prefix), the appropriate separator will be inferred automat-
-       ically, and you won't need this rule.

-   if block
-              if MATCHER
-               RULE
-
-              if
-              MATCHER
-              MATCHER
-              MATCHER
-               RULE
-               RULE
-
-       Conditional blocks ("if blocks") are a block of rules that are  applied
-       only  to CSV records which match certain patterns.  They are often used
-       for customising account names based on transaction descriptions.
-
-   Matching the whole record
-       Each MATCHER can be a record matcher, which looks like this:
-
-              REGEX
-
-       REGEX is a case-insensitive regular expression that tries to match any-
-       where  within  the  CSV  record.   It  is a POSIX ERE (extended regular
-       expression) that also supports GNU word boundaries (\b,  \B,  \<,  \>),
-       and  nothing  else.   If  you  have  trouble, be sure to check our doc:
-       https://hledger.org/hledger.html#regular-expressions
-
-       Important note: the record that is matched is not the original  record,
-       but  a synthetic one, with any enclosing double quotes (but not enclos-
-       ing whitespace) removed, and always comma-separated (which means that a
-       field  containing  a  comma  will  appear like two fields).  Eg, if the
-       original record is 2020-01-01; "Acme, Inc.";   1,000,  the  REGEX  will
-       actually see 2020-01-01,Acme, Inc.,  1,000).
-
-   Matching individual fields
-       Or, MATCHER can be a field matcher, like this:
-
-              %CSVFIELD REGEX
-
-       which  matches just the content of a particular CSV field.  CSVFIELD is
-       a percent sign followed by the field's  name  or  column  number,  like
-       %date or %1.
-
-   Combining matchers
-       A single matcher can be written on the same line as the "if"; or multi-
-       ple matchers can be written on the following lines, non-indented.  Mul-
-       tiple  matchers are OR'd (any one of them can match), unless one begins
-       with an & symbol, in which case it is AND'ed with the previous matcher.
-
-              if
-              MATCHER
-              & MATCHER
-               RULE
-
-   Rules applied on successful match
-       After  the  patterns  there  should  be one or more rules to apply, all
-       indented by at least one space.  Three kinds of  rule  are  allowed  in
-       conditional blocks:
-
-       o field assignments (to set a hledger field)
-
-       o skip (to skip the matched CSV record)
-
-       o end (to skip all remaining CSV records).
-
-       Examples:
-
-              # if the CSV record contains "groceries", set account2 to "expenses:groceries"
-              if groceries
-               account2 expenses:groceries
-
-              # if the CSV record contains any of these patterns, set account2 and comment as shown
-              if
-              monthly service fee
-              atm transaction fee
-              banking thru software
-               account2 expenses:business:banking
-               comment  XXX deductible ? check it
-
-   if table
-              if,CSVFIELDNAME1,CSVFIELDNAME2,...,CSVFIELDNAMEn
-              MATCHER1,VALUE11,VALUE12,...,VALUE1n
-              MATCHER2,VALUE21,VALUE22,...,VALUE2n
-              MATCHER3,VALUE31,VALUE32,...,VALUE3n
-              <empty line>
-
-       Conditional  tables  ("if  tables")  are  a different syntax to specify
-       field assignments that will be applied only to CSV records which  match
-       certain patterns.
-
-       MATCHER  could  be  either field or record matcher, as described above.
-       When MATCHER matches, values from that row would be assigned to the CSV
-       fields named on the if line, in the same order.
-
-       Therefore if table is exactly equivalent to a sequence of of if blocks:
-
-              if MATCHER1
-                CSVFIELDNAME1 VALUE11
-                CSVFIELDNAME2 VALUE12
-                ...
-                CSVFIELDNAMEn VALUE1n
-
-              if MATCHER2
-                CSVFIELDNAME1 VALUE21
-                CSVFIELDNAME2 VALUE22
-                ...
-                CSVFIELDNAMEn VALUE2n
-
-              if MATCHER3
-                CSVFIELDNAME1 VALUE31
-                CSVFIELDNAME2 VALUE32
-                ...
-                CSVFIELDNAMEn VALUE3n
-
-       Each line starting with MATCHER should contain enough (possibly  empty)
-       values for all the listed fields.
-
-       Rules  would be checked and applied in the order they are listed in the
-       table and, like with if blocks, later rules (in the same or another ta-
-       ble) or if blocks could override the effect of any rule.
-
-       Instead  of ',' you can use a variety of other non-alphanumeric charac-
-       ters as a separator.  First character after if is taken to be the sepa-
-       rator  for the rest of the table.  It is the responsibility of the user
-       to ensure that separator does not occur inside MATCHERs  and  values  -
-       there is no way to escape separator.
-
-       Example:
-
-              if,account2,comment
-              atm transaction fee,expenses:business:banking,deductible? check it
-              %description groceries,expenses:groceries,
-              2020/01/12.*Plumbing LLC,expenses:house:upkeep,emergency plumbing call-out
-
-   end
-       This  rule  can  be  used inside if blocks (only), to make hledger stop
-       reading this CSV file and move on to the next input file, or to command
-       execution.  Eg:
-
-              # ignore everything following the first empty record
-              if ,,,,
-               end
-
-   date-format
-              date-format DATEFMT
-
-       This  is  a  helper for the date (and date2) fields.  If your CSV dates
-       are not formatted like YYYY-MM-DD,  YYYY/MM/DD  or  YYYY.MM.DD,  you'll
-       need  to  add  a  date-format rule describing them with a strptime date
-       parsing pattern, which must parse the CSV date value completely.   Some
-       examples:
-
-              # MM/DD/YY
-              date-format %m/%d/%y
-
-              # D/M/YYYY
-              # The - makes leading zeros optional.
-              date-format %-d/%-m/%Y
-
-              # YYYY-Mmm-DD
-              date-format %Y-%h-%d
-
-              # M/D/YYYY HH:MM AM some other junk
-              # Note the time and junk must be fully parsed, though only the date is used.
-              date-format %-m/%-d/%Y %l:%M %p some other junk
-
-       For the supported strptime syntax, see:
-       https://hackage.haskell.org/package/time/docs/Data-Time-For-
-       mat.html#v:formatTime
-
-       Note that although you can parse date-times which include a time  zone,
-       that  time zone is ignored; it will not change the date that is parsed.
-       This means when reading CSV data with times  not  in  your  local  time
-       zone, dates can be "off by one".
-
-   decimal-mark
-              decimal-mark .
-
-       or:
-
-              decimal-mark ,
-
-       hledger  automatically accepts either period or comma as a decimal mark
-       when parsing numbers (cf Amounts).  However if any numbers in  the  CSV
-       contain  digit  group  marks,  such  as thousand-separating commas, you
-       should declare the decimal mark explicitly with  this  rule,  to  avoid
-       misparsed numbers.
-
-   newest-first
-       hledger  always sorts the generated transactions by date.  Transactions
-       on the same date should appear in the same order as their CSV  records,
-       as  hledger  can  usually auto-detect whether the CSV's normal order is
-       oldest first or newest first.  But if all of the following are true:
-
-       o the CSV might sometimes contain just one day  of  data  (all  records
-         having the same date)
-
-       o the  CSV  records are normally in reverse chronological order (newest
-         at the top)
-
-       o and you care about preserving the order of same-day transactions
-
-       then, you should add the newest-first rule as a hint.  Eg:
-
-              # tell hledger explicitly that the CSV is normally newest first
-              newest-first
-
-   include
-              include RULESFILE
-
-       This includes the contents of another CSV rules  file  at  this  point.
-       RULESFILE  is  an  absolute file path or a path relative to the current
-       file's directory.  This can be useful for sharing common rules  between
-       several rules files, eg:
-
-              # someaccount.csv.rules
-
-              ## someaccount-specific rules
-              fields   date,description,amount
-              account1 assets:someaccount
-              account2 expenses:misc
-
-              ## common rules
-              include categorisation.rules
-
-   balance-type
-       Balance assertions generated by assigning to balanceN are of the simple
-       = type by default, which is  a  single-commodity,  subaccount-excluding
-       assertion.  You may find the subaccount-including variants more useful,
-       eg if you have created some virtual subaccounts  of  checking  to  help
-       with  budgeting.  You can select a different type of assertion with the
-       balance-type rule:
-
-              # balance assertions will consider all commodities and all subaccounts
-              balance-type ==*
-
-       Here are the balance assertion types for quick reference:
-
-              =    single commodity, exclude subaccounts
-              =*   single commodity, include subaccounts
-              ==   multi commodity,  exclude subaccounts
-              ==*  multi commodity,  include subaccounts
-
-   Tips
-   Rapid feedback
-       It's a good idea to get rapid feedback  while  creating/troubleshooting
-       CSV rules.  Here's a good way, using entr from http://eradman.com/entr-
-       project :
-
-              $ ls foo.csv* | entr bash -c 'echo ----; hledger -f foo.csv print desc:SOMEDESC'
-
-       A desc: query (eg) is used to select just one, or a  few,  transactions
-       of  interest.   "bash  -c"  is used to run multiple commands, so we can
-       echo a separator each time the command re-runs,  making  it  easier  to
-       read the output.
-
-   Valid CSV
-       hledger  accepts  CSV  conforming  to  RFC  4180.   When CSV values are
-       enclosed in quotes, note:
-
-       o they must be double quotes (not single quotes)
-
-       o spaces outside the quotes are not allowed
-
-   File Extension
-       To help hledger identify the format and show the right error  messages,
-       CSV/SSV/TSV  files  should  normally be named with a .csv, .ssv or .tsv
-       filename extension.  Or, the file path should be  prefixed  with  csv:,
-       ssv: or tsv:.  Eg:
-
-              $ hledger -f foo.ssv print
-
-       or:
-
-              $ cat foo | hledger -f ssv:- foo
-
-       You  can  override  the file extension with a separator rule if needed.
-       See also: Input files in the hledger manual.
-
-   Reading multiple CSV files
-       If you use multiple -f options to read  multiple  CSV  files  at  once,
-       hledger  will  look for a correspondingly-named rules file for each CSV
-       file.  But if you use the --rules-file option, that rules file will  be
-       used for all the CSV files.
-
-   Valid transactions
-       After reading a CSV file, hledger post-processes and validates the gen-
-       erated journal entries as it would for a journal file - balancing them,
-       applying  balance  assignments,  and canonicalising amount styles.  Any
-       errors at this stage will be reported in the usual way, displaying  the
-       problem entry.
-
-       There is one exception: balance assertions, if you have generated them,
-       will not be checked, since normally these will work only when  the  CSV
-       data  is  part  of  the  main journal.  If you do need to check balance
-       assertions generated from CSV right away, pipe into another hledger:
-
-              $ hledger -f file.csv print | hledger -f- print
-
-   Deduplicating, importing
-       When you download a CSV file periodically, eg to get your  latest  bank
-       transactions,  the  new  file  may overlap with the old one, containing
-       some of the same records.
-
-       The import command will (a) detect the new transactions, and (b) append
-       just those transactions to your main journal.  It is idempotent, so you
-       don't have to remember how many times you ran it or with which  version
-       of  the  CSV.  (It keeps state in a hidden .latest.FILE.csv file.) This
-       is the easiest way to import CSV data.  Eg:
-
-              # download the latest CSV files, then run this command.
-              # Note, no -f flags needed here.
-              $ hledger import *.csv [--dry]
-
-       This method works for most CSV files.  (Where  records  have  a  stable
-       chronological order, and new records appear only at the new end.)
-
-       A  number of other tools and workflows, hledger-specific and otherwise,
-       exist for converting, deduplicating, classifying and managing CSV data.
-       See:

-
-   Setting amounts
-       Some tips on using the amount-setting rules discussed above.
-
-       Here are the ways to set a posting's amount:
-
-       1. If the CSV has a single amount field:
-       Assign (via a fields list or a field assignment) to amountN.  This sets
-       the Nth posting's amount.  N is usually 1 or 2 but can go up to 99.
-
-       2. If the CSV has separate amount fields for debit & credit (in & out):
-
-           a. If both fields are unsigned:
-           Assign to amountN-in and amountN-out.  This sets posting N's amount
-           to whichever of these has a non-zero value, and negates the  "-out"
-           value.
-
-           b. If either field is signed (can contain a minus sign):
-           Use  a  conditional  rule  to  flip the sign (of non-empty values).
-           Since hledger always negates amountN-out, if it was  already  nega-
-           tive,  we  must  undo  that  by negating once more (but only if the
-           field is non-empty):
-
-                  fields date, description, amount1-in, amount1-out
-                  if %amount1-out [1-9]
-                   amount1-out -%amount1-out
-
-           c. If both fields, or neither field, can contain a non-zero value:
-           hledger normally expects exactly one of the fields to have  a  non-
-           zero  value.   Eg,  the  amountN-in/amountN-out  rules would reject
-           value pairs like these:
-
-                  "",  ""
-                  "0", "0"
-                  "1", "none"
-
-           So, use smarter conditional rules to set the amount from the appro-
-           priate  field.   Eg,  these  rules would make it use only the value
-           containing non-zero digits, handling the above:
-
-                  fields date, description, in, out
-                  if %in [1-9]
-                   amount1 %in
-                  if %out [1-9]
-                   amount1 %out
-
-       3. If you are stuck with hledger <1.17, or you want posting 2's  amount
-          converted to cost:
-       Assign to amount (or to amount-in and amount-out).  (The old numberless
-       syntax, which sets amount1 and amount2.)
-
-       4. If the CSV has the balance instead of the transaction amount:
-       Assign to balanceN, which sets posting N's amount indirectly via a bal-
-       ance assignment.  (Old syntax: balance, equivalent to balance1.)
-
-           o If hledger guesses the wrong default account name:
-           When  setting  the  amount via balance assertion, hledger may guess
-           the wrong default account name.  So, set the account  name  explic-
-           itly, eg:
-
-                    fields date, description, balance1
-                    account1 assets:checking
-
-   Amount signs
-       There  is  some  special handling for amount signs, to simplify parsing
-       and sign-flipping:
-
-       o If an amount value begins with a plus sign:
-       that will be removed: +AMT becomes AMT
-
-       o If an amount value is parenthesised:
-       it will be de-parenthesised and sign-flipped: (AMT) becomes -AMT
-
-       o If an amount value has two minus signs (or two sets  of  parentheses,
-         or a minus sign and parentheses):
-       they cancel out and will be removed: --AMT or -(AMT) becomes AMT
-
-       o If  an  amount value contains just a sign (or just a set of parenthe-
-         ses):
-       that is removed, making it an empty value.  "+" or "-" or "()"  becomes
-       "".
-
-   Setting currency/commodity
-       If  the  currency/commodity  symbol  is  included  in  the CSV's amount
-       field(s):
-
-              2020-01-01,foo,$123.00
-
-       you don't have to do anything special for the commodity symbol, it will
-       be assigned as part of the amount.  Eg:
-
-              fields date,description,amount
-
-              2020-01-01 foo
-                  expenses:unknown         $123.00
-                  income:unknown          $-123.00
-
-       If the currency is provided as a separate CSV field:
-
-              2020-01-01,foo,USD,123.00
-
-       You can assign that to the currency pseudo-field, which has the special
-       effect of prepending itself to every amount in the transaction (on  the
-       left, with no separating space):
-
-              fields date,description,currency,amount
-
-              2020-01-01 foo
-                  expenses:unknown       USD123.00
-                  income:unknown        USD-123.00
-
-       Or,  you  can  use a field assignment to construct the amount yourself,
-       with more control.  Eg to put the symbol on the right, and separated by
-       a space:
-
-              fields date,description,cur,amt
-              amount %amt %cur
-
-              2020-01-01 foo
-                  expenses:unknown        123.00 USD
-                  income:unknown         -123.00 USD
-
-       Note  we  used a temporary field name (cur) that is not currency - that
-       would trigger the prepending effect, which we don't want here.
-
-   Amount decimal places
-       Like amounts in a journal file, the amounts generated by CSV rules like
-       amount1 influence commodity display styles, such as the number of deci-
-       mal places displayed in reports.
-
-       The original amounts as written in the CSV file do not  affect  display
-       style (because we don't yet reliably know their commodity).
-
-   Referencing other fields
-       In  field assignments, you can interpolate only CSV fields, not hledger
-       fields.  In the example below, there's both a CSV field and  a  hledger
-       field  named  amount1, but %amount1 always means the CSV field, not the
-       hledger field:
-
-              # Name the third CSV field "amount1"
-              fields date,description,amount1
-
-              # Set hledger's amount1 to the CSV amount1 field followed by USD
-              amount1 %amount1 USD
-
-              # Set comment to the CSV amount1 (not the amount1 assigned above)
-              comment %amount1
-
-       Here, since there's no CSV amount1 field, %amount1 will produce a  lit-
-       eral "amount1":
-
-              fields date,description,csvamount
-              amount1 %csvamount USD
-              # Can't interpolate amount1 here
-              comment %amount1
-
-       When  there  are  multiple field assignments to the same hledger field,
-       only the last one takes effect.  Here, comment's value will be be B, or
-       C if "something" is matched, but never A:
-
-              comment A
-              comment B
-              if something
-               comment C
-
-   How CSV rules are evaluated
-       Here's  how  to  think of CSV rules being evaluated (if you really need
-       to).  First,
-
-       o include - all includes are inlined, from top to bottom, depth  first.
-         (At  each  include  point the file is inlined and scanned for further
-         includes, recursively, before proceeding.)
-
-       Then "global" rules are  evaluated,  top  to  bottom.   If  a  rule  is
-       repeated, the last one wins:
-
-       o skip (at top level)
-
-       o date-format
-
-       o newest-first
-
-       o fields - names the CSV fields, optionally sets up initial assignments
-         to hledger fields
-
-       Then for each CSV record in turn:
-
-       o test all if blocks.  If any of them contain  a  end  rule,  skip  all
-         remaining CSV records.  Otherwise if any of them contain a skip rule,
-         skip that many CSV records.   If  there  are  multiple  matched  skip
-         rules, the first one wins.
-
-       o collect  all field assignments at top level and in matched if blocks.
-         When there are multiple assignments for a field, keep only  the  last
-         one.
-
-       o compute  a  value  for  each  hledger field - either the one that was
-         assigned to it (and interpolate the %CSVFIELDNAME references),  or  a
-         default
-
-       o generate a synthetic hledger transaction from these values.
-
-       This  is all part of the CSV reader, one of several readers hledger can
-       use to parse input files.  When all files have been read  successfully,
-       the  transactions  are passed as input to whichever hledger command the
-       user specified.
-
-TIMECLOCK FORMAT
-       The time logging format of timeclock.el, as read by hledger.
-
-       hledger can read time logs in timeclock format.  As with Ledger,  these
-       are (a subset of) timeclock.el's format, containing clock-in and clock-
-       out entries as in the example below.  The date is a simple  date.   The
-       time  format is HH:MM[:SS][+-ZZZZ].  Seconds and timezone are optional.
-       The timezone, if present, must be four digits and is ignored (currently
-       the time is always interpreted as a local time).
-
-              i 2015/03/30 09:00:00 some:account name  optional description after two spaces
-              o 2015/03/30 09:20:00
-              i 2015/03/31 22:21:45 another account
-              o 2015/04/01 02:00:34
-
-       hledger  treats  each  clock-in/clock-out pair as a transaction posting
-       some number of hours to an account.  Or if the session spans more  than
-       one  day, it is split into several transactions, one for each day.  For
-       the above time log, hledger print generates these journal entries:
-
-              $ hledger -f t.timeclock print
-              2015-03-30 * optional description after two spaces
-                  (some:account name)         0.33h
-
-              2015-03-31 * 22:21-23:59
-                  (another account)         1.64h
-
-              2015-04-01 * 00:00-02:00
-                  (another account)         2.01h
-
-       Here is a sample.timeclock to download and some queries to try:
-
-              $ hledger -f sample.timeclock balance                               # current time balances
-              $ hledger -f sample.timeclock register -p 2009/3                    # sessions in march 2009
-              $ hledger -f sample.timeclock register -p weekly --depth 1 --empty  # time summary by week
-
-       To generate time logs, ie to clock in and clock out, you could:
-
-       o use emacs and the built-in timeclock.el, or the  extended  timeclock-
-         x.el and perhaps the extras in ledgerutils.el
-
-       o at the command line, use these bash aliases: shell     alias ti="echo
-         i `date '+%Y-%m-%d %H:%M:%S'` \$* >>$TIMELOG"      alias  to="echo  o
-         `date '+%Y-%m-%d %H:%M:%S'` >>$TIMELOG"
-
-       o or use the old ti and to scripts in the ledger 2.x repository.  These
-         rely on a "timeclock" executable which I think is just the  ledger  2
-         executable renamed.
-
-TIMEDOT FORMAT
-       hledger's human-friendly time logging format.
-
-       Timedot  is  a plain text format for logging dated, categorised quanti-
-       ties (of time, usually), supported by hledger.  It  is  convenient  for
-       approximate  and retroactive time logging, eg when the real-time clock-
-       in/out required with a timeclock file is too precise or  too  interrup-
-       tive.   It  can be formatted like a bar chart, making clear at a glance
-       where time was spent.
-
-       Though called "timedot", this format is read by hledger  as  commodity-
-       less  quantities,  so  it  could  be used to represent dated quantities
-       other than time.  In the docs below we'll assume it's time.
-
-       A timedot file contains a series of day entries.  A  day  entry  begins
-       with  a  non-indented hledger-style simple date (Y-M-D, Y/M/D, Y.M.D..)
-       Any additional text on the same line is used as a transaction  descrip-
-       tion for this day.
-
-       This is followed by optionally-indented timelog items for that day, one
-       per   line.    Each   timelog   item   is    a    note,    usually    a
-       hledger:style:account:name  representing  a  time category, followed by
-       two or more spaces, and a quantity.   Each  timelog  item  generates  a
-       hledger transaction.
-
-       Quantities can be written as:
-
-       o dots:  a sequence of dots (.) representing quarter hours.  Spaces may
-         optionally be used for grouping.  Eg: ....  ..
-
-       o an integral or decimal number, representing hours.  Eg: 1.5
-
-       o an integral or decimal number immediately followed by a  unit  symbol
-         s,  m,  h, d, w, mo, or y, representing seconds, minutes, hours, days
-         weeks, months or years respectively.  Eg: 90m.  The following equiva-
-         lencies  are  assumed,  currently: 1m = 60s, 1h = 60m, 1d = 24h, 1w =
-         7d, 1mo = 30d, 1y=365d.
-
-       There is some flexibility allowing notes and  todo  lists  to  be  kept
-       right in the time log, if needed:
-
-       o Blank lines and lines beginning with # or ; are ignored.
-
-       o Lines not ending with a double-space and quantity are parsed as items
-         taking no time, which will not appear in balance reports by  default.
-         (Add -E to see them.)
-
-       o Org  mode headlines (lines beginning with one or more * followed by a
-         space) can be used as date lines or  timelog  items  (the  stars  are
-         ignored).   Also  all  org  headlines  before the first date line are
-         ignored.  This means org users can manage their  timelog  as  an  org
-         outline  (eg  using  org-mode/orgstruct-mode in Emacs), for organisa-
-         tion, faster navigation, controlling visibility etc.
-
-       Examples:
-
-              # on this day, 6h was spent on client work, 1.5h on haskell FOSS work, etc.

-
-   Constructing command lines
-       hledger  has  an  extensive  and  powerful  command line interface.  We
-       strive to keep it simple and ergonomic, but you may run into one of the
-       confusing real world details described in OPTIONS, below.  If that hap-
-       pens, here are some tips that may help:
-
-       o command-specific options must go after the command (it's fine to  put
-         all options there) (hledger CMD OPTS ARGS)
-
-       o running  add-on  executables directly simplifies command line parsing
-         (hledger-ui OPTS ARGS)
-
-       o enclose "problematic" args in single quotes
-
-       o if needed, also add a backslash to hide regular expression  metachar-
-         acters from the shell
-
-       o to see how a misbehaving command is being parsed, add --debug=2.
-
-   Starting a journal file
-       hledger   looks   for   your   accounting   data  in  a  journal  file,
-       $HOME/.hledger.journal by default:
-
-              $ hledger stats
-              The hledger journal file "/Users/simon/.hledger.journal" was not found.
-              Please create it first, eg with "hledger add" or a text editor.
-              Or, specify an existing journal file with -f or LEDGER_FILE.
-
-       You can override this by setting the LEDGER_FILE environment  variable.
-       It's a good practice to keep this important file under version control,
-       and to start a new file each year.  So  you  could  do  something  like
-       this:
-
-              $ mkdir ~/finance
-              $ cd ~/finance
-              $ git init
-              Initialized empty Git repository in /Users/simon/finance/.git/
-              $ touch 2020.journal
-              $ echo "export LEDGER_FILE=$HOME/finance/2020.journal" >> ~/.bashrc
-              $ source ~/.bashrc
-              $ hledger stats
-              Main file                : /Users/simon/finance/2020.journal
-              Included files           :
-              Transactions span        :  to  (0 days)
-              Last transaction         : none
-              Transactions             : 0 (0.0 per day)
-              Transactions last 30 days: 0 (0.0 per day)
-              Transactions last 7 days : 0 (0.0 per day)
-              Payees/descriptions      : 0
-              Accounts                 : 0 (depth 0)
-              Commodities              : 0 ()
-              Market prices            : 0 ()
-
-   Setting opening balances
-       Pick  a  starting  date  for which you can look up the balances of some
-       real-world assets (bank accounts,  wallet..)  and  liabilities  (credit
-       cards..).
-
-       To  avoid  a  lot of data entry, you may want to start with just one or
-       two accounts, like your checking account or cash  wallet;  and  pick  a
-       recent  starting  date,  like  today or the start of the week.  You can
-       always come back later and add more accounts and older transactions, eg
-       going back to january 1st.
-
-       Add  an opening balances transaction to the journal, declaring the bal-
-       ances on this date.  Here are two ways to do it:
-
-       o The first way: open the journal in any text editor and save an  entry
-         like this:
-
-                2020-01-01 * opening balances
-                    assets:bank:checking                $1000   = $1000
-                    assets:bank:savings                 $2000   = $2000
-                    assets:cash                          $100   = $100
-                    liabilities:creditcard               $-50   = $-50
-                    equity:opening/closing balances
-
-         These  are  start-of-day  balances, ie whatever was in the account at
-         the end of the previous day.
-
-         The * after the date is an  optional  status  flag.   Here  it  means
-         "cleared & confirmed".
-
-         The  currency symbols are optional, but usually a good idea as you'll
-         be dealing with multiple currencies sooner or later.
-
-         The = amounts are optional balance assertions, providing extra  error
-         checking.
-
-       o The  second  way:  run hledger add and follow the prompts to record a
-         similar transaction:
-
-                $ hledger add
-                Adding transactions to journal file /Users/simon/finance/2020.journal
-                Any command line arguments will be used as defaults.
-                Use tab key to complete, readline keys to edit, enter to accept defaults.
-                An optional (CODE) may follow transaction dates.
-                An optional ; COMMENT may follow descriptions or amounts.
-                If you make a mistake, enter < at any prompt to go one step backward.
-                To end a transaction, enter . when prompted.
-                To quit, enter . at a date prompt or press control-d or control-c.

-
-       If you're using version control, this could be a good  time  to  commit
-       the journal.  Eg:
-
-              $ git commit -m 'initial balances' 2020.journal
-
-   Recording transactions
-       As  you spend or receive money, you can record these transactions using
-       one of the methods above (text editor, hledger add)  or  by  using  the
-       hledger-iadd  or hledger-web add-ons, or by using the import command to
-       convert CSV data downloaded from your bank.
-
-       Here are some simple transactions, see  the  hledger_journal(5)  manual
-       and hledger.org for more ideas:
-
-              2020/1/10 * gift received
-                assets:cash   $20
-                income:gifts
-
-              2020.1.12 * farmers market
-                expenses:food    $13
-                assets:cash
-
-              2020-01-15 paycheck
-                income:salary
-                assets:bank:checking    $1000
-
-   Reconciling
-       Periodically  you should reconcile - compare your hledger-reported bal-
-       ances against external sources of truth, like bank statements  or  your
-       bank's  website - to be sure that your ledger accurately represents the
-       real-world balances (and, that the  real-world  institutions  have  not
-       made  a  mistake!).   This gets easy and fast with (1) practice and (2)
-       frequency.  If you do it daily, it can take 2-10 minutes.  If  you  let
-       it  pile  up, expect it to take longer as you hunt down errors and dis-
-       crepancies.
-
-       A typical workflow:
-
-       1. Reconcile cash.  Count what's in your  wallet.   Compare  with  what
-          hledger  reports  (hledger bal cash).  If they are different, try to
-          remember the missing transaction, or  look  for  the  error  in  the
-          already-recorded  transactions.   A  register  report can be helpful
-          (hledger reg cash).  If you can't find the error, add an  adjustment
-          transaction.  Eg if you have $105 after the above, and can't explain
-          the missing $2, it could be:
-
-                  2020-01-16 * adjust cash
-                      assets:cash    $-2 = $105
-                      expenses:misc
-
-       2. Reconcile checking.  Log in to your bank's website.  Compare today's
-          (cleared) balance with hledger's cleared balance (hledger bal check-
-          ing -C).  If they are different, track down the error or record  the
-          missing  transaction(s) or add an adjustment transaction, similar to
-          the above.  Unlike the cash case, you can usually compare the trans-
-          action  history  and  running  balance  from  your bank with the one
-          reported by hledger reg checking -C.  This will  be  easier  if  you
-          generally  record  transaction  dates  quite  similar to your bank's
-          clearing dates.
-
-       3. Repeat for other asset/liability accounts.
-
-       Tip: instead of the register command, use hledger-ui  to  see  a  live-
-       updating register while you edit the journal: hledger-ui --watch --reg-
-       ister checking -C
-
-       After reconciling, it could be a  good  time  to  mark  the  reconciled
-       transactions'  status  as "cleared and confirmed", if you want to track
-       that, by adding the * marker.  Eg in the  paycheck  transaction  above,
-       insert * between 2020-01-15 and paycheck
-
-       If  you're using version control, this can be another good time to com-
-       mit:
-
-              $ git commit -m 'txns' 2020.journal

-
-   Migrating to a new file
-       At  the end of the year, you may want to continue your journal in a new
-       file, so that old transactions don't slow down or clutter your reports,
-       and  to  help ensure the integrity of your accounting history.  See the
-       close command.
-
-       If using version control, don't forget to git add the new file.
-
-LIMITATIONS
-       The need to precede add-on command options with --  when  invoked  from
-       hledger is awkward.
-
-       When input data contains non-ascii characters, a suitable system locale
-       must be configured (or there will be an unhelpful error).  Eg on POSIX,
-       set LANG to something other than C.
-
-       In a Microsoft Windows CMD window, non-ascii characters and colours are
-       not supported.
-
-       On Windows, non-ascii characters may not display correctly when running
-       a hledger built in CMD in MSYS/CYGWIN, or vice-versa.
-
-       In a Cygwin/MSYS/Mintty window, the tab key is not supported in hledger
-       add.
-
-       Not all of Ledger's journal file syntax is supported.  See file  format
-       differences.
-
-       On  large  data  files,  hledger  is  slower  and uses more memory than
-       Ledger.
-
-TROUBLESHOOTING
-       Here are some issues you might encounter  when  you  run  hledger  (and
-       remember  you can also seek help from the IRC channel, mail list or bug
-       tracker):
-
-       Successfully installed, but "No command 'hledger' found"
-       stack and cabal install binaries into a special directory, which should
-       be  added  to your PATH environment variable.  Eg on unix-like systems,
-       that is ~/.local/bin and ~/.cabal/bin respectively.
-
-       I set a custom LEDGER_FILE, but hledger is still using the default file
-       LEDGER_FILE  should  be  a  real environment variable, not just a shell
-       variable.  The command env | grep LEDGER_FILE should show it.  You  may
-       need to use export.  Here's an explanation.
-
-       Getting  errors  like "Illegal byte sequence" or "Invalid or incomplete
-       multibyte or wide character" or "commitAndReleaseBuffer: invalid  argu-
-       ment (invalid character)"
-       Programs compiled with GHC (hledger, haskell build tools, etc.) need to
-       have a UTF-8-aware locale configured in the environment, otherwise they
-       will  fail  with  these  kinds  of errors when they encounter non-ascii
-       characters.
-
-       To fix it, set the LANG environment variable to some locale which  sup-
-       ports UTF-8.  The locale you choose must be installed on your system.
-
-       Here's an example of setting LANG temporarily, on Ubuntu GNU/Linux:
-
-              $ file my.journal
-              my.journal: UTF-8 Unicode text         # the file is UTF8-encoded
-              $ echo $LANG
-              C                                      # LANG is set to the default locale, which does not support UTF8
-              $ locale -a                            # which locales are installed ?
-              C
-              en_US.utf8                             # here's a UTF8-aware one we can use
-              POSIX
-              $ LANG=en_US.utf8 hledger -f my.journal print   # ensure it is used for this command
-
-       If  available,  C.UTF-8 will also work.  If your preferred locale isn't
-       listed  by  locale  -a,  you  might  need  to  install   it.    Eg   on
-       Ubuntu/Debian:
-
-              $ apt-get install language-pack-fr
-              $ locale -a
-              C
-              en_US.utf8

+       manual is for hledger 1.22.2.
+
+SYNOPSIS
+       hledger
+
+       hledger [-f FILE] COMMAND [OPTIONS] [ARGS]
+
+       hledger [-f FILE] ADDONCMD -- [OPTIONS] [ARGS]
+
+DESCRIPTION
+       hledger  is  a  reliable,  cross-platform  set of programs for tracking
+       money, time, or any other commodity, using double-entry accounting  and
+       a  simple,  editable  file  format.  hledger is inspired by and largely
+       compatible with ledger(1).
+
+       The basic function of the hledger CLI is to  read  a  plain  text  file
+       describing financial transactions (in accounting terms, a general jour-
+       nal) and print useful reports on standard output,  or  export  them  as
+       CSV.   hledger can also read some other file formats such as CSV files,
+       translating them to journal format.  Additionally, hledger lists  other
+       hledger-*  executables found in the user's $PATH and can invoke them as
+       subcommands.
+
+       hledger reads data from one or more files  in  hledger  journal,  time-
+       clock,  timedot,  or  CSV format specified with -f, or $LEDGER_FILE, or
+       $HOME/.hledger.journal          (on          windows,           perhaps
+       C:/Users/USER/.hledger.journal).  If using $LEDGER_FILE, note this must
+       be a real environment variable, not a shell variable.  You can  specify
+       standard input with -f-.
+
+       Transactions  are  dated movements of money between two (or more) named
+       accounts, and are recorded with journal entries like this:
+
+              2015/10/16 bought food
+               expenses:food          $10
+               assets:cash
+
+       Most users use a text editor to edit the journal, usually with an  edi-
+       tor mode such as ledger-mode for added convenience.  hledger's interac-
+       tive add command is another way to record  new  transactions.   hledger
+       never changes existing transactions.
+
+       To  get  started,  you  can  either save some entries like the above in
+       ~/.hledger.journal, or run hledger add and follow  the  prompts.   Then
+       try  some  commands like hledger print or hledger balance.  Run hledger
+       with no arguments for a list of commands.
+
+OPTIONS
+   General options

+              using period expressions syntax
+
+       --date2
+              match the secondary date instead (see  command  help  for  other
+              effects)
+
+       -U --unmarked
+              include only unmarked postings/txns (can combine with -P or -C)
+
+       -P --pending
+              include only pending postings/txns
+
+       -C --cleared
+              include only cleared postings/txns
+
+       -R --real
+              include only non-virtual postings
+
+       -NUM --depth=NUM
+              hide/aggregate accounts or postings more than NUM levels deep
+
+       -E --empty
+              show  items with zero amount, normally hidden (and vice-versa in
+              hledger-ui/hledger-web)
+
+       -B --cost
+              convert amounts to their cost/selling amount at transaction time
+
+       -V --market
+              convert  amounts to their market value in default valuation com-
+              modities
+
+       -X --exchange=COMM
+              convert amounts to their market value in commodity COMM
+
+       --value
+              convert amounts to cost or  market  value,  more  flexibly  than
+              -B/-V/-X
+
+       --infer-market-prices
+              use  transaction  prices  (recorded  with @ or @@) as additional
+              market prices, as if they were P directives
+
+       --auto apply automated posting rules to modify transactions.
+
+       --forecast
+              generate future transactions from  periodic  transaction  rules,
+              for  the  next 6 months or till report end date.  In hledger-ui,
+              also make ordinary future transactions visible.
+
+       --color=WHEN (or --colour=WHEN)
+              Should color-supporting commands use ANSI color  codes  in  text
+              output.   'auto' (default): whenever stdout seems to be a color-
+              supporting terminal.  'always' or 'yes': always, useful eg  when
+              piping  output  into  'less  -R'.   'never'  or  'no': never.  A
+              NO_COLOR environment variable overrides this.
+
+       When a reporting option appears more than once in the command line, the
+       last one takes precedence.
+
+       Some reporting options can also be written as query arguments.
+
+   Command options
+       To  see  options  for  a particular command, including command-specific
+       options, run: hledger COMMAND -h.
+
+       Command-specific options must be written after the  command  name,  eg:
+       hledger print -x.
+
+       Additionally,  if  the  command  is  an add-on, you may need to put its
+       options after a double-hyphen, eg: hledger ui -- --watch.  Or, you  can
+       run the add-on executable directly: hledger-ui --watch.
+
+   Command arguments
+       Most  hledger  commands  accept arguments after the command name, which
+       are often a query, filtering the data in some way.
+
+       You can save a set of command line options/arguments  in  a  file,  and
+       then  reuse  them by writing @FILENAME as a command line argument.  Eg:
+       hledger bal @foo.args.  (To prevent this, eg if you  have  an  argument
+       that  begins  with  a literal @, precede it with --, eg: hledger bal --
+       @ARG).
+
+       Inside the argument file, each line should contain just one  option  or
+       argument.  Avoid the use of spaces, except inside quotes (or you'll see
+       a confusing error).  Between a flag and its argument, use =  (or  noth-
+       ing).  Bad:
+
+              assets depth:2
+              -X USD
+
+       Good:
+
+              assets
+              depth:2
+              -X=USD
+
+       For  special characters (see below), use one less level of quoting than
+       you would at the command prompt.  Bad:
+
+              -X"$"
+
+       Good:
+
+              -X$
+
+       See also: Save frequently used options.
+
+   Special characters
+   Single escaping (shell metacharacters)
+       In shell command lines, characters significant to your shell - such  as
+       spaces,  <, >, (, ), |, $ and \ - should be "shell-escaped" if you want
+       hledger to see them.  This is done by enclosing them in single or  dou-
+       ble  quotes,  or  by  writing  a backslash before them.  Eg to match an
+       account name containing a space:
+
+              $ hledger register 'credit card'
+
+       or:
+
+              $ hledger register credit\ card
+
+       Windows users should keep in mind that cmd treats  single  quote  as  a
+       regular  character,  so  you should be using double quotes exclusively.
+       PowerShell treats both single and double quotes as quotes.
+
+   Double escaping (regular expression metacharacters)
+       Characters significant in regular expressions (described below) -  such
+       as  .,  ^,  $, [, ], (, ), |, and \ - may need to be "regex-escaped" if
+       you don't want them to be interpreted by hledger's  regular  expression
+       engine.   This  is  done  by writing backslashes before them, but since
+       backslash is typically also a shell metacharacter, both  shell-escaping
+       and  regex-escaping will be needed.  Eg to match a literal $ sign while
+       using the bash shell:
+
+              $ hledger balance cur:'\$'
+
+       or:
+
+              $ hledger balance cur:\\$
+
+   Triple escaping (for add-on commands)
+       When you use hledger to  run  an  external  add-on  command  (described
+       below),  one  level of shell-escaping is lost from any options or argu-
+       ments intended for by the add-on command, so those need an extra  level
+       of  shell-escaping.   Eg to match a literal $ sign while using the bash
+       shell and running an add-on command (ui):
+
+              $ hledger ui cur:'\\$'
+
+       or:
+
+              $ hledger ui cur:\\\\$
+
+       If you wondered why four backslashes, perhaps this helps:
+
+
+       unescaped:        $
+       escaped:          \$
+       double-escaped:   \\$
+       triple-escaped:   \\\\$
+
+       Or, you can avoid the extra escaping by running the  add-on  executable
+       directly:
+
+              $ hledger-ui cur:\\$
+
+   Less escaping
+       Options and arguments are sometimes used in places other than the shell
+       command line, where shell-escaping is not needed, so there  you  should
+       use one less level of escaping.  Those places include:
+
+       o an @argumentfile
+
+       o hledger-ui's filter field
+
+       o hledger-web's search form
+
+       o GHCI's prompt (used by developers).
+
+   Unicode characters
+       hledger is expected to handle non-ascii characters correctly:
+
+       o they  should  be  parsed  correctly in input files and on the command
+         line, by all hledger tools (add, iadd, hledger-web's  search/add/edit
+         forms, etc.)
+
+       o they  should  be  displayed  correctly  by all hledger tools, and on-
+         screen alignment should be preserved.
+
+       This requires a well-configured environment.  Here are some tips:
+
+       o A system locale must be configured, and  it  must  be  one  that  can
+         decode the characters being used.  In bash, you can set a locale like
+         this: export LANG=en_US.UTF-8.  There are some more details in  Trou-
+         bleshooting.   This step is essential - without it, hledger will quit
+         on encountering a non-ascii character (as with all GHC-compiled  pro-
+         grams).
+
+       o your  terminal  software  (eg  Terminal.app, iTerm, CMD.exe, xterm..)
+         must support unicode
+
+       o the terminal must be using a font which includes the required unicode
+         glyphs
+
+       o the  terminal should be configured to display wide characters as dou-
+         ble width (for report alignment)
+
+       o on Windows, for best results you should run hledger in the same  kind
+         of  environment in which it was built.  Eg hledger built in the stan-
+         dard CMD.EXE environment (like the binaries  on  our  download  page)
+         might  show  display  problems when run in a cygwin or msys terminal,
+         and vice versa.  (See eg #961).
+
+   Regular expressions
+       hledger uses regular expressions in a number of places:
+
+       o query terms, on the command line and in the hledger-web search  form:
+         REGEX, desc:REGEX, cur:REGEX, tag:...=REGEX
+
+       o CSV rules conditional blocks: if REGEX ...
+
+       o account  alias  directives  and options: alias /REGEX/ = REPLACEMENT,
+         --alias /REGEX/=REPLACEMENT
+
+       hledger's regular expressions come from  the  regex-tdfa  library.   If
+       they're  not doing what you expect, it's important to know exactly what
+       they support:
+
+       1. they are case insensitive
+
+       2. they are infix matching (they do not need to match the entire  thing
+          being matched)
+
+       3. they are POSIX ERE (extended regular expressions)
+
+       4. they also support GNU word boundaries (\b, \B, \<, \>)
+
+       5. they  do  not support backreferences; if you write \1, it will match
+          the digit 1.  Except when doing  text  replacement,  eg  in  account
+          aliases,  where backreferences can be used in the replacement string
+          to reference capturing groups in the search regexp.
+
+       6. they do not support mode modifiers ((?s)),  character  classes  (\w,
+          \d), or anything else not mentioned above.
+
+       Some things to note:
+
+       o In  the  alias directive and --alias option, regular expressions must
+         be enclosed in forward  slashes  (/REGEX/).   Elsewhere  in  hledger,
+         these are not required.
+
+       o In  queries,  to match a regular expression metacharacter like $ as a
+         literal character, prepend a backslash.  Eg  to  search  for  amounts
+         with the dollar sign in hledger-web, write cur:\$.
+
+       o On  the command line, some metacharacters like $ have a special mean-
+         ing to the shell and so must be escaped at least once more.  See Spe-
+         cial characters.
+
+ENVIRONMENT
+       LEDGER_FILE The journal file path when not specified with -f.  Default:
+       ~/.hledger.journal (on  windows,  perhaps  C:/Users/USER/.hledger.jour-
+       nal).
+
+       A  typical  value  is  ~/DIR/YYYY.journal,  where DIR is a version-con-
+       trolled finance directory and YYYY is the current year.  Or  ~/DIR/cur-
+       rent.journal, where current.journal is a symbolic link to YYYY.journal.
+
+       On Mac computers, you can set this and other environment variables in a
+       more  thorough  way that also affects applications started from the GUI
+       (say,  an  Emacs  dock  icon).   Eg  on  MacOS  Catalina   I   have   a
+       ~/.MacOSX/environment.plist file containing
+
+              {
+                "LEDGER_FILE" : "~/finance/current.journal"
+              }
+
+       To see the effect you may need to killall Dock, or reboot.
+
+       COLUMNS  The  screen  width used by the register command.  Default: the
+       full terminal width.
+
+       NO_COLOR If this variable exists with any value, hledger will  not  use
+       ANSI   color   codes   in   terminal   output.    This   overrides  the
+       --color/--colour option.
+
+DATA FILES
+       hledger reads transactions from one or more data  files.   The  default
+       data  file  is  $HOME/.hledger.journal  (or  on Windows, something like
+       C:/Users/USER/.hledger.journal).
+
+       You can override this with the $LEDGER_FILE environment variable:
+
+              $ setenv LEDGER_FILE ~/finance/2016.journal
+              $ hledger stats
+
+       or with one or more -f/--file options:
+
+              $ hledger -f /some/file -f another_file stats
+
+       The file name - means standard input:
+
+              $ cat some.journal | hledger -f-
+
+   Data formats
+       Usually the data file is in hledger's journal format, but it can be  in
+       any of the supported file formats, which currently are:
+
+
+       Reader:    Reads:                                    Used  for  file  exten-
+                                                            sions:

+       shown  above.   If  it  can't  recognise the file extension, it assumes
+       journal format.  So for non-journal files,  it's  important  to  use  a
+       recognised file extension, so as to either read successfully or to show
+       relevant error messages.
+
+       You can also force a specific reader/format by prefixing the file  path
+       with the format and a colon.  Eg, to read a .dat file as csv format:
+
+              $ hledger -f csv:/some/csv-file.dat stats
+
+       Or to read stdin (-) as timeclock format:
+
+              $ echo 'i 2009/13/1 08:00:00' | hledger print -ftimeclock:-
+
+   Multiple files
+       You  can specify multiple -f options, to read multiple files as one big
+       journal.  There are some limitations with this:
+
+       o most directives do not affect sibling files
+
+       o balance assertions will not see any account  balances  from  previous
+         files
+
+       If you need either of those things, you can
+
+       o use a single parent file which includes the others
+
+       o or  concatenate  the files into one before reading, eg: cat a.journal
+         b.journal | hledger -f- CMD.
+
+   Strict mode
+       hledger checks input files for valid data.  By default, the most impor-
+       tant  errors  are  detected,  while  still accepting easy journal files
+       without a lot of declarations:
+
+       o Are the input files parseable, with valid syntax ?
+
+       o Are all transactions balanced ?
+
+       o Do all balance assertions pass ?
+
+       With the -s/--strict flag, additional checks are performed:
+
+       o Are all accounts posted to, declared  with  an  account  directive  ?
+         (Account error checking)
+
+       o Are all commodities declared with a commodity directive ?  (Commodity
+         error checking)
+
+       o Are all commodity conversions declared explicitly ?
+
+       You can also use the check command to run  these  and  some  additional
+       checks.
+
+TIME PERIODS
+   Smart dates
+       hledger's user interfaces accept a flexible "smart date" syntax.  Smart
+       dates allow some english words, can be relative to  today's  date,  and
+       can have less-significant date parts omitted (defaulting to 1).
+
+       Examples:
+
+
+       2004/10/1,   2004-01-01,   exact date, several separators allowed.   Year
+       2004.9.1                   is 4+ digits, month is 1-12, day is 1-31
+       2004                       start of year
+       2004/10                    start of month
+       10/1                       month and day in current year
+       21                         day in current month
+       october, oct               start of month in current year
+       yesterday, today, tomor-   -1, 0, 1 days from today
+       row
+       last/this/next             -1, 0, 1 periods from the current period
+       day/week/month/quar-
+       ter/year
+       20181201                   8 digit YYYYMMDD with valid year month and day
+       201812                     6 digit YYYYMM with valid year and month
+
+       Counterexamples  -  malformed  digit  sequences  might  give surprising
+       results:
+
+
+       201813        6 digits with an  invalid  month  is  parsed  as  start  of
+                     6-digit year
+       20181301      8  digits  with  an  invalid  month  is  parsed as start of
+                     8-digit year
+       20181232      8 digits with an invalid day gives an error
+       201801012     9+ digits beginning with a valid YYYYMMDD gives an error
+
+
+   Report start & end date
+       By default, most hledger reports will show the full span of time repre-
+       sented by the journal data.  The report start date will be the earliest
+       transaction or posting date, and the report end date will be the latest
+       transaction, posting, or market price date.
+
+       Often  you  will  want  to see a shorter time span, such as the current
+       month.  You can specify a  start  and/or  end  date  using  -b/--begin,
+       -e/--end, -p/--period or a date: query (described below).  All of these
+       accept the smart date syntax.
+
+       Some notes:
+
+       o As in Ledger, end dates are exclusive, so you need to write the  date
+         after the last day you want to include.
+
+       o As  noted  in reporting options: among start/end dates specified with
+         options, the last (i.e.  right-most) option takes precedence.
+
+       o The effective report start and end dates are the intersection of  the
+         start/end  dates  from options and that from date: queries.  That is,
+         date:2019-01 date:2019 -p'2000 to  2030'  yields  January  2019,  the
+         smallest common time span.
+
+       o A  report  interval  (see  below)  will  adjust start/end dates, when
+         needed, so that they fall on subperiod boundaries.
+
+       Examples:
+
+
+       -b 2016/3/17       begin on St. Patrick's day 2016
+       -e 12/1            end  at  the  start  of  december  1st of the current year
+                          (11/30 will be the last date included)
+       -b thismonth       all transactions on or after the 1st of the current month
+       -p thismonth       all transactions in the current month
+       date:2016/3/17..   the  above  written  as  queries  instead  (.. can also be
+                          replaced with -)
+       date:..12/1
+       date:thismonth..
+       date:thismonth
+
+   Report intervals
+       A report interval can be specified so that commands like register, bal-
+       ance and activity become multi-period, showing each subperiod as a sep-
+       arate row or column.
+
+       The following "standard" report intervals can be enabled by using their
+       corresponding flag:
+
+       -D/--daily, -W/--weekly, -M/--monthly, -Q/--quarterly, -Y/--yearly.
+
+       These standard intervals always start on natural  interval  boundaries:
+       eg  --weekly  starts  on  mondays, --monthly starts on the first of the
+       month, --yearly always starts on January 1st, etc.
+
+       Certain more complex intervals, and more flexible boundary  dates,  can
+       be  specified  by  -p/--period.   These are described in period expres-
+       sions, below.
+
+       Report intervals can only be specified by the flags above, and  not  by
+       query arguments, currently.
+
+       Report  intervals  have another effect: multi-period reports are always
+       expanded to fill a whole number of subperiods.  So if you use a  report
+       interval  (other  than  --daily), and you have specified a start or end
+       date, you may notice those  dates  being  overridden  (ie,  the  report
+       starts  earlier than your requested start date, or ends later than your
+       requested end date).  This is done to ensure "full" first and last sub-
+       periods, so that all subperiods' numbers are comparable.
+
+   Period expressions
+       The  -p/--period  option accepts period expressions, a shorthand way of
+       expressing a start date, end date, and/or report interval all at  once.
+
+       Here's  a basic period expression specifying the first quarter of 2009.
+       Note, hledger always treats start dates as inclusive and end  dates  as
+       exclusive:
+
+       -p "from 2009/1/1 to 2009/4/1"
+
+       Keywords  like  "from" and "to" are optional, and so are the spaces, as
+       long as you don't run two dates together.  "to" can also be written  as
+       ".." or "-".  These are equivalent to the above:
+
+
+       -p "2009/1/1 2009/4/1"
+       -p2009/1/1to2009/4/1
+       -p2009/1/1..2009/4/1
+
+       Dates  are  smart  dates, so if the current year is 2009, the above can
+       also be written as:
+
+
+       -p "1/1 4/1"
+
+       -p "january-apr"
+       -p "this year to 4/1"
+
+       If you specify only one date, the missing start or end date will be the
+       earliest or latest transaction in your journal:
+
+
+       -p "from 2009/1/1"   everything  after  january
+                            1, 2009
+       -p "from 2009/1"     the same
+       -p "from 2009"       the same
+       -p "to 2009"         everything before  january
+                            1, 2009
+
+       A  single  date  with  no "from" or "to" defines both the start and end
+       date like so:
+
+
+       -p "2009"       the year 2009;  equivalent
+                       to "2009/1/1 to 2010/1/1"
+       -p "2009/1"     the  month of jan; equiva-
+                       lent   to   "2009/1/1   to
+                       2009/2/1"
+       -p "2009/1/1"   just  that day; equivalent
+                       to "2009/1/1 to 2009/1/2"
+
+       Or you can specify a single quarter like so:
+
+
+       -p "2009Q1"   first  quarter  of   2009,
+                     equivalent to "2009/1/1 to
+                     2009/4/1"
+       -p "q4"       fourth quarter of the cur-
+                     rent year
+
+       The  argument  of  -p  can  also  begin  with, or be, a report interval
+       expression.  The basic report intervals  are  daily,  weekly,  monthly,
+       quarterly, or yearly, which have the same effect as the -D,-W,-M,-Q, or
+       -Y flags.  Between report interval and start/end dates  (if  any),  the
+       word in is optional.  Examples:
+
+
+       -p "weekly from 2009/1/1 to 2009/4/1"
+       -p "monthly in 2008"
+       -p "quarterly"
+
+       Note  that  weekly, monthly, quarterly and yearly intervals will always
+       start on the first day on week, month, quarter or year accordingly, and
+       will  end  on  the  last  day of same period, even if associated period
+       expression specifies different explicit start and end date.
+
+       For example:
+
+
+       -p "weekly from  2009/1/1   starts on 2008/12/29, closest preceding Mon-
+       to 2009/4/1"                day
+       -p      "monthly       in   starts on 2018/11/01
+       2008/11/25"
+       -p     "quarterly    from   starts  on  2009/04/01,  ends on 2009/06/30,
+       2009-05-05 to 2009-06-01"   which are first and last days of Q2 2009
+       -p      "yearly      from   starts on 2009/01/01, first day of 2009
+       2009-12-29"
+
+       The  following  more  complex  report  intervals  are  also  supported:
+       biweekly, fortnightly,  bimonthly,  every  day|week|month|quarter|year,
+       every N days|weeks|months|quarters|years.
+
+       All  of  these  will start on the first day of the requested period and
+       end on the last one, as described above.
+
+       Examples:
+
+
+       -p "bimonthly from 2008"    periods will have boundaries on  2008/01/01,
+                                   2008/03/01, ...
+       -p "every 2 weeks"          starts on closest preceding Monday
+       -p  "every  5  month from   periods will have boundaries on  2009/03/01,
+       2009/03"                    2009/08/01, ...
+
+       If  you want intervals that start on arbitrary day of your choosing and
+       span a week, month or year, you need to use any of the following:
+
+       every    Nth     day     of     week,     every     WEEKDAYNAME     (eg
+       mon|tue|wed|thu|fri|sat|sun), every Nth day [of month], every Nth WEEK-
+       DAYNAME [of month], every MM/DD [of year], every  Nth  MMM  [of  year],
+       every MMM Nth [of year].
+
+       Examples:
+
+
+       -p  "every  2nd  day  of   periods will go from Tue to Tue
+       week"
+       -p "every Tue"             same
+       -p "every 15th day"        period boundaries will  be  on  15th  of  each
+                                  month
+       -p "every 2nd Monday"      period  boundaries will be on second Monday of
+                                  each month
+       -p "every 11/05"           yearly periods with boundaries on 5th of Nov
+       -p "every 5th Nov"         same
+       -p "every Nov 5th"         same
+
+       Show historical balances at end of 15th each month (N is exclusive  end
+       date):
+
+       hledger balance -H -p "every 16th day"
+
+       Group  postings  from  start  of wednesday to end of next tuesday (N is
+       start date and exclusive end date):
+
+       hledger register checking -p "every 3rd day of week"
+
+DEPTH
+       With the --depth N option (short form: -N), commands like account, bal-
+       ance  and register will show only the uppermost accounts in the account
+       tree, down to level N.  Use this when you  want  a  summary  with  less
+       detail.   This  flag has the same effect as a depth: query argument (so
+       -2, --depth=2 or depth:2 are equivalent).
+
+QUERIES
+       One of hledger's strengths is being able to quickly report on a precise
+       subset of your data.  Most hledger commands accept optional query argu-
+       ments to restrict their scope.  The syntax is as follows:
+
+       o Zero or more space-separated  query  terms.   These  are  most  often
+         account name substrings:
+
+         utilities food:groceries
+
+       o Terms  with  spaces or other special characters should be enclosed in
+         quotes:
+
+         "personal care"
+
+       o Regular expressions are also supported:
+
+         "^expenses\b" "accounts (payable|receivable)"
+
+       o Add a query type prefix to match other parts of the data:
+
+         date:202012- desc:amazon cur:USD amt:">100" status:
+
+       o Add a not: prefix to negate a term:
+
+         not:cur:USD
+
+   Query types
+       Here are the types of query term available.  Remember these can also be
+       prefixed with not: to convert them into a negative match.
+
+       acct:REGEX, REGEX
+       Match  account names containing this (case insensitive) regular expres-
+       sion.  This is the default query type when there is no prefix, and reg-
+       ular  expression  syntax  is  typically  not needed, so usually we just
+       write an account name substring, like expenses or food.
+
+       amt:N, amt:<N, amt:<=N, amt:>N, amt:>=N
+       Match postings with a single-commodity amount equal to, less  than,  or
+       greater  than N.  (Postings with multi-commodity amounts are not tested
+       and will always match.) The comparison has two modes: if N is  preceded
+       by  a + or - sign (or is 0), the two signed numbers are compared.  Oth-
+       erwise, the absolute magnitudes are compared, ignoring sign.
+
+       code:REGEX
+       Match by transaction code (eg check number).
+
+       cur:REGEX
+       Match  postings  or  transactions  including  any  amounts  whose  cur-
+       rency/commodity  symbol  is  fully  matched  by  REGEX.  (For a partial
+       match, use .*REGEX.*).  Note, to match  special  characters  which  are
+       regex-significant,  you need to escape them with \.  And for characters
+       which are significant to your shell you may  need  one  more  level  of
+       escaping.  So eg to match the dollar sign:
+       hledger print cur:\\$.
+
+       desc:REGEX
+       Match transaction descriptions.
+
+       date:PERIODEXPR
+       Match  dates  (or  with  the  --date2 flag, secondary dates) within the
+       specified period.  PERIODEXPR is a period  expression  with  no  report
+       interval.  Examples:
+       date:2016, date:thismonth, date:2/1-2/15, date:2021-07-27..nextquarter.
+
+       date2:PERIODEXPR
+       Match secondary dates within the specified period (independent  of  the
+       --date2 flag).
+
+       depth:N
+       Match  (or  display,  depending  on  command) accounts at or above this
+       depth.
+
+       note:REGEX
+       Match transaction notes (the part of the description right of |, or the
+       whole description if there's no |).
+
+       payee:REGEX
+       Match  transaction  payee/payer names (the part of the description left
+       of |, or the whole description if there's no |).
+
+       real:, real:0
+       Match real or virtual postings respectively.
+
+       status:, status:!, status:*
+       Match unmarked, pending, or cleared transactions respectively.
+
+       tag:REGEX[=REGEX]
+       Match by tag name, and optionally also by tag value.  (To match only by
+       value,  use  tag:.=REGEX.)  Note  that  postings also inherit tags from
+       their transaction, and transactions also acquire tags from their  post-
+       ings, when querying.
+
+       (inacct:ACCTNAME
+       A  special  query  term  used  automatically in hledger-web only: tells
+       hledger-web to show the transaction register for an account.)
+
+   Combining query terms
+       Most commands select things which match:
+
+       o any of the description terms AND
+
+       o any of the account terms AND
+
+       o any of the status terms AND
+
+       o all the other terms.
+
+       while the print command shows transactions which:
+
+       o match any of the description terms AND
+
+       o have any postings matching any of the positive account terms AND
+
+       o have no postings matching any of the negative account terms AND
+
+       o match all the other terms.
+
+       You can do more powerful queries (such as AND-ing two  like  terms)  by
+       running  a  first query with print, and piping the result into a second
+       hledger command.  Eg: how much of food expenses was paid with cash ?
+
+              $ hledger print assets:cash | hledger f- -I balance expenses:food
+
+       If you are interested in full  boolean  expressions  for  queries,  see
+       #203.
+
+   Queries and command options
+       Some  queries can also be expressed as command-line options: depth:2 is
+       equivalent to --depth 2, date:2020 is equivalent to -p 2020, etc.  When
+       you  mix  command  options and query arguments, generally the resulting
+       query is their intersection.
+
+   Queries and account aliases
+       When account names are rewritten with  --alias  or  alias,  acct:  will
+       match either the old or the new account name.
+
+   Queries and valuation
+       When  amounts  are  converted  to  other  commodities  in cost or value
+       reports, cur: and amt: match the  old  commodity  symbol  and  the  old
+       amount  quantity, not the new ones (except in hledger 1.22.0 where it's
+       reversed, see #1625).
+
+   Querying with account aliases
+       When account names are rewritten with --alias or alias, note that acct:
+       will match either the old or the new account name.
+
+   Querying with cost or value
+       When  amounts  are  converted  to  other  commodities  in cost or value
+       reports, note that cur: matches the new commodity symbol, and  not  the
+       old one, and amt: matches the new quantity, and not the old one.  Note:
+       this changed in hledger 1.22, previously it was the  reverse,  see  the
+       discussion at #1625.
+
+COSTING
+       The  -B/--cost  flag  converts  amounts to their cost or sale amount at
+       transaction time, if they have a transaction price specified.  If  this
+       flag  is supplied, hledger will perform cost conversion first, and will
+       apply any market price valuations (if requested) afterwards.
+
+VALUATION
+       Instead of reporting amounts in their original commodity,  hledger  can
+       convert them to cost/sale amount (using the conversion rate recorded in
+       the transaction), and/or to market value (using some market price on  a
+       certain  date).   This  is  controlled  by the --value=TYPE[,COMMODITY]
+       option, which will be described below.  We also provide the simpler  -V
+       and -X COMMODITY options, and often one of these is all you need:
+
+   -V: Value
+       The  -V/--market flag converts amounts to market value in their default
+       valuation commodity, using the market prices in effect on the valuation
+       date(s), if any.  More on these in a minute.
+
+   -X: Value in specified commodity
+       The -X/--exchange=COMM option is like -V, except you tell it which cur-
+       rency you want to convert to, and it tries  to  convert  everything  to
+       that.
+
+   Valuation date
+       Since  market  prices  can change from day to day, market value reports
+       have a valuation date (or more than one), which determines which market
+       prices will be used.
+
+       For single period reports, if an explicit report end date is specified,
+       that will be used as the valuation date; otherwise the  valuation  date
+       is the journal's end date.
+
+       For  multiperiod  reports, each column/period is valued on the last day
+       of the period, by default.
+
+   Market prices
+       To convert a commodity A to its market value in  another  commodity  B,
+       hledger  looks  for a suitable market price (exchange rate) as follows,
+       in this order of preference :
+
+       1. A declared market price or inferred market price: A's latest  market
+          price in B on or before the valuation date as declared by a P direc-
+          tive, or (with the --infer-market-price flag) inferred from transac-
+          tion prices.
+
+       2. A reverse market price: the inverse of a declared or inferred market
+          price from B to A.
+
+       3. A forward chain of market prices: a synthetic price formed  by  com-
+          bining the shortest chain of "forward" (only 1 above) market prices,
+          leading from A to B.
+
+       4. Any chain of market prices: a chain of any market prices,  including
+          both  forward  and reverse prices (1 and 2 above), leading from A to
+          B.
+
+       There is a limit to the  length  of  these  price  chains;  if  hledger
+       reaches  that length without finding a complete chain or exhausting all
+       possibilities, it will give up (with a "gave  up"  message  visible  in
+       --debug=2 output).  That limit is currently 1000.
+
+       Amounts  for  which no suitable market price can be found, are not con-
+       verted.
+
+   --infer-market-price: market prices from transactions
+       Normally, market value in hledger is fully controlled by, and requires,
+       P directives in your journal.  Since adding and updating those can be a
+       chore, and since transactions usually take place  at  close  to  market
+       value, why not use the recorded transaction prices as additional market
+       prices (as Ledger does) ?  We could produce value reports without need-
+       ing P directives at all.
+
+       Adding the --infer-market-price flag to -V, -X or --value enables this.
+       So for example, hledger bs  -V  --infer-market-price  will  get  market
+       prices  both  from  P  directives  and from transactions.  (And if both
+       occur on the same day, the P directive takes precedence).
+
+       There is a downside: value reports can sometimes be affected in confus-
+       ing/undesired  ways  by  your journal entries.  If this happens to you,
+       read all of this Valuation section carefully, and try adding --debug or
+       --debug=2 to troubleshoot.
+
+       --infer-market-price can infer market prices from:
+
+       o multicommodity transactions with explicit prices (@/@@)
+
+       o multicommodity  transactions with implicit prices (no @, two commodi-
+         ties, unbalanced).  (With  these,  the  order  of  postings  matters.
+         hledger print -x can be useful for troubleshooting.)
+
+       o but  not,  currently, from "more correct" multicommodity transactions
+         (no @, multiple commodities, balanced).
+
+   Valuation commodity
+       When you specify a valuation commodity (-X COMM or --value TYPE,COMM):
+       hledger will convert all amounts to COMM, wherever it can find a  suit-
+       able market price (including by reversing or chaining prices).
+
+       When  you  leave  the  valuation  commodity  unspecified (-V or --value
+       TYPE):
+       For each commodity A, hledger picks a default  valuation  commodity  as
+       follows, in this order of preference:
+
+       1. The price commodity from the latest P-declared market price for A on
+          or before valuation date.
+
+       2. The price commodity from the latest P-declared market price for A on
+          any  date.   (Allows  conversion  to proceed when there are inferred
+          prices before the valuation date.)
+
+       3. If there are no P directives at all (any commodity or date) and  the
+          --infer-market-price flag is used: the price commodity from the lat-
+          est transaction-inferred price for A on or before valuation date.
+
+       This means:
+
+       o If you have P directives, they determine which  commodities  -V  will
+         convert, and to what.
+
+       o If  you  have no P directives, and use the --infer-market-price flag,
+         transaction prices determine it.
+
+       Amounts for which no valuation commodity can  be  found  are  not  con-
+       verted.
+
+   Simple valuation examples
+       Here are some quick examples of -V:
+
+              ; one euro is worth this many dollars from nov 1
+              P 2016/11/01 EUR $1.10
+
+              ; purchase some euros on nov 3
+              2016/11/3
+                  assets:euros        EUR100
+                  assets:checking
+
+              ; the euro is worth fewer dollars by dec 21
+              P 2016/12/21 EUR $1.03
+
+       How many euros do I have ?
+
+              $ hledger -f t.j bal -N euros
+                              EUR100  assets:euros
+
+       What are they worth at end of nov 3 ?
+
+              $ hledger -f t.j bal -N euros -V -e 2016/11/4
+                           $110.00  assets:euros
+
+       What  are they worth after 2016/12/21 ?  (no report end date specified,
+       defaults to today)
+
+              $ hledger -f t.j bal -N euros -V
+                           $103.00  assets:euros
+
+   --value: Flexible valuation
+       -V and -X are special cases of the more general --value option:
+
+               --value=TYPE[,COMM]  TYPE is then, end, now or YYYY-MM-DD.
+                                    COMM is an optional commodity symbol.
+                                    Shows amounts converted to:
+                                    - default valuation commodity (or COMM) using market prices at posting dates
+                                    - default valuation commodity (or COMM) using market prices at period end(s)
+                                    - default valuation commodity (or COMM) using current market prices
+                                    - default valuation commodity (or COMM) using market prices at some date
+
+       The TYPE part selects cost or value and valuation date:
+
+       --value=then
+              Convert amounts to their value in the default valuation  commod-
+              ity, using market prices on each posting's date.
+
+       --value=end
+              Convert  amounts to their value in the default valuation commod-
+              ity, using market prices on the last day of  the  report  period
+              (or  if  unspecified, the journal's end date); or in multiperiod
+              reports, market prices on the last day of each subperiod.
+
+       --value=now
+              Convert amounts to their value in the default valuation  commod-
+              ity  using  current  market  prices (as of when report is gener-
+              ated).
+
+       --value=YYYY-MM-DD
+              Convert amounts to their value in the default valuation  commod-
+              ity using market prices on this date.
+
+       To select a different valuation commodity, add the optional ,COMM part:
+       a comma, then the  target  commodity's  symbol.   Eg:  --value=now,EUR.
+       hledger will do its best to convert amounts to this commodity, deducing
+       market prices as described above.

+
+       You  may  need  to  explicitly  set  a  commodity's display style, when
+       reverse prices are used.  Eg this output might be surprising:
+
+              P 2000-01-01 A 2B
+
+              2000-01-01
+                a  1B
+                b
+
+              $ hledger print -x -X A
+              2000-01-01
+                  a               0
+                  b               0
+
+       Explanation: because there's no amount or commodity directive  specify-
+       ing  a display style for A, 0.5A gets the default style, which shows no
+       decimal digits.  Because the displayed amount looks like zero, the com-
+       modity  symbol  and minus sign are not displayed either.  Adding a com-
+       modity directive sets a more useful display style for A:
+
+              P 2000-01-01 A 2B
+              commodity 0.00A
+
+              2000-01-01
+                a  1B
+                b
+
+              $ hledger print -X A
+              2000-01-01
+                  a           0.50A
+                  b          -0.50A
+
+   Effect of valuation on reports
+       Here is a reference for how valuation is supposed to affect  each  part
+       of  hledger's  reports  (and  a  glossary).  (It's wide, you'll have to
+       scroll sideways.) It may be useful when troubleshooting.  If  you  find

+              a  flag (-D/-W/-M/-Q/-Y) or period expression that activates the
+              report's multi-period mode (whether showing one or many subperi-
+              ods).
+
+PIVOTING
+       Normally hledger sums amounts, and organizes them in a hierarchy, based
+       on account name.  The --pivot FIELD option causes it to sum  and  orga-
+       nize  hierarchy  based on the value of some other field instead.  FIELD
+       can be: code, description, payee, note, or the full name (case insensi-
+       tive) of any tag.  As with account names, values containing colon:sepa-
+       rated:parts will be displayed hierarchically in reports.
+
+       --pivot is a general option affecting all reports;  you  can  think  of
+       hledger transforming the journal before any other processing, replacing
+       every posting's account name with the value of the specified  field  on
+       that posting, inheriting it from the transaction or using a blank value
+       if it's not present.
+
+       An example:
+
+              2016/02/16 Member Fee Payment
+                  assets:bank account                    2 EUR
+                  income:member fees                    -2 EUR  ; member: John Doe
+
+       Normal balance report showing account names:
+
+              $ hledger balance
+                             2 EUR  assets:bank account
+                            -2 EUR  income:member fees
+              --------------------
+                                 0
+
+       Pivoted balance report, using member: tag values instead:
+
+              $ hledger balance --pivot member
+                             2 EUR
+                            -2 EUR  John Doe
+              --------------------
+                                 0
+
+       One way to show only amounts with  a  member:  value  (using  a  query,
+       described below):
+
+              $ hledger balance --pivot member tag:member=.
+                            -2 EUR  John Doe
+              --------------------
+                            -2 EUR
+
+       Another  way  (the  acct:  query  matches  against the pivoted "account
+       name"):
+
+              $ hledger balance --pivot member acct:.
+                            -2 EUR  John Doe
+              --------------------
+                            -2 EUR
+
+OUTPUT
+   Output destination
+       hledger commands send their output to the terminal by default.  You can
+       of course redirect this, eg into a file, using standard shell syntax:
+
+              $ hledger print > foo.txt
+
+       Some  commands (print, register, stats, the balance commands) also pro-
+       vide the -o/--output-file option, which does  the  same  thing  without
+       needing the shell.  Eg:
+
+              $ hledger print -o foo.txt
+              $ hledger print -o -        # write to stdout (the default)
+
+       hledger   can   optionally   produce  debug  output  (if  enabled  with
+       --debug=N); this goes to stderr, and is not  affected  by  -o/--output-
+       file.   If you need to capture it, use shell redirects, eg: hledger bal
+       --debug=3 >file 2>&1.
+
+   Output format
+       Some commands (print, register, the balance commands) offer a choice of
+       output format.  In addition to the usual plain text format (txt), there
+       are CSV (csv), HTML (html), JSON (json) and SQL (sql).   This  is  con-
+       trolled by the -O/--output-format option:
+
+              $ hledger print -O csv
+
+       or, by a file extension specified with -o/--output-file:
+
+              $ hledger balancesheet -o foo.html   # write HTML to foo.html
+
+       The -O option can be used to override the file extension if needed:
+
+              $ hledger balancesheet -o foo.txt -O html   # write HTML to foo.txt
+
+       Some notes about JSON output:
+
+       o This  feature  is  marked  experimental,  and  not yet much used; you
+         should expect our JSON to evolve.  Real-world feedback is welcome.
+
+       o Our JSON is rather large and verbose, as it is quite a faithful  rep-
+         resentation  of  hledger's  internal  data  types.  To understand the
+         JSON,  read  the  Haskell  type  definitions,  which  are  mostly  in
+         https://github.com/simonmichael/hledger/blob/master/hledger-
+         lib/Hledger/Data/Types.hs.
+
+       o hledger represents quantities as Decimal values  storing  up  to  255
+         significant  digits,  eg  for  repeating  decimals.  Such numbers can
+         arise in practice (from automatically-calculated transaction prices),
+         and  would break most JSON consumers.  So in JSON, we show quantities
+         as simple Numbers with at most 10 decimal places.  We don't limit the
+         number  of  integer  digits, but that part is under your control.  We
+         hope this approach will not cause problems in practice; if  you  find
+         otherwise, please let us know.  (Cf #1195)
+
+       Notes about SQL output:
+
+       o SQL  output is also marked experimental, and much like JSON could use
+         real-world feedback.
+
+       o SQL output is expected to work with sqlite, MySQL and PostgreSQL
+
+       o SQL output is structured with the expectations that  statements  will
+         be  executed  in the empty database.  If you already have tables cre-
+         ated via SQL output of hledger, you would  probably  want  to  either
+         clear tables of existing data (via delete or truncate SQL statements)
+         or drop tables completely as otherwise your postings will be duped.
+
+COMMANDS
+       hledger provides a number of commands for producing reports and  manag-
+       ing  your  data.   Run  hledger  with no arguments to list the commands
+       available, and hledger CMD to run a command.  CMD can be the full  com-
+       mand  name, or its standard abbreviation shown in the commands list, or
+       any unambiguous prefix of the name.  Eg: hledger bal.
+
+       Here are the built-in commands, with the most often-used in bold:

+       commands;  these  appear  in  the  commands list with a + mark.  Two of
+       these are maintained and released with hledger:
+
+       o ui - an efficient terminal interface (TUI) for hledger

+
+       Next, the detailed command docs, in alphabetical order.
+
+   accounts
+       accounts
+       Show account names.
+
+       This command lists account names, either declared with  account  direc-
+       tives  (--declared),  posted  to (--used), or both (the default).  With
+       query arguments, only matched account names and  account  names  refer-
+       enced  by matched postings are shown.  It shows a flat list by default.
+       With --tree, it uses indentation to show  the  account  hierarchy.   In
+       flat  mode you can add --drop N to omit the first few account name com-
+       ponents.  Account names can be depth-clipped with depth:N or --depth  N
+       or -N.
+
+       Examples:
+
+              $ hledger accounts
+              assets:bank:checking
+              assets:bank:saving
+              assets:cash
+              expenses:food
+              expenses:supplies
+              income:gifts
+              income:salary
+              liabilities:debts
+
+   activity
+       activity
+       Show an ascii barchart of posting counts per interval.
+
+       The  activity  command  displays an ascii histogram showing transaction
+       counts by day, week, month or other reporting interval (by day  is  the
+       default).  With query arguments, it counts only matched transactions.
+
+       Examples:
+
+              $ hledger activity --quarterly
+              2008-01-01 **
+              2008-04-01 *******
+              2008-07-01
+              2008-10-01 **
+
+   add
+       add
+       Prompt  for  transactions  and  add them to the journal.  Any arguments
+       will be used as default inputs for the first N prompts.
+
+       Many hledger users edit their journals directly with a text editor,  or
+       generate  them from CSV.  For more interactive data entry, there is the
+       add command, which prompts interactively on the console for new  trans-
+       actions, and appends them to the journal file (if there are multiple -f
+       FILE options, the first file is used.) Existing  transactions  are  not
+       changed.   This  is the only hledger command that writes to the journal
+       file.
+
+       To use it, just run hledger add and follow the prompts.  You can add as
+       many  transactions as you like; when you are finished, enter . or press
+       control-d or control-c to exit.
+
+       Features:
+
+       o add tries to provide useful defaults,  using  the  most  similar  (by
+         description)  recent transaction (filtered by the query, if any) as a
+         template.
+
+       o You can also set the initial defaults with command line arguments.
+
+       o Readline-style edit keys can be used during data entry.
+
+       o The tab key will auto-complete whenever possible - accounts, descrip-
+         tions,  dates  (yesterday,  today,  tomorrow).   If the input area is
+         empty, it will insert the default value.
+
+       o If the journal defines a default commodity, it will be added  to  any
+         bare numbers entered.
+
+       o A parenthesised transaction code may be entered following a date.
+
+       o Comments and tags may be entered following a description or amount.
+
+       o If you make a mistake, enter < at any prompt to go one step backward.
+
+       o Input prompts are displayed in a different colour when  the  terminal
+         supports it.
+
+       Example (see the tutorial for a detailed explanation):
+
+              $ hledger add
+              Adding transactions to journal file /src/hledger/examples/sample.journal
+              Any command line arguments will be used as defaults.
+              Use tab key to complete, readline keys to edit, enter to accept defaults.
+              An optional (CODE) may follow transaction dates.
+              An optional ; COMMENT may follow descriptions or amounts.
+              If you make a mistake, enter < at any prompt to go one step backward.
+              To end a transaction, enter . when prompted.
+              To quit, enter . at a date prompt or press control-d or control-c.

+              Date [2015/05/22]: <CTRL-D> $
+
+       On  Microsoft  Windows,  the add command makes sure that no part of the
+       file path ends with a period, as that would cause problems (#1056).
+
+   aregister
+       aregister, areg
+
+       Show the transactions  and  running  historical  balance  of  a  single
+       account, with each transaction displayed as one line.
+
+       aregister shows the overall transactions affecting a particular account
+       (and any subaccounts).  Each report line represents one transaction  in
+       this  account.   Transactions  before  the report start date are always
+       included in the running balance (--historical mode is always on).
+
+       This is a more "real world", bank-like view than the  register  command
+       (which  shows individual postings, possibly from multiple accounts, not
+       necessarily in historical mode).  As a quick rule of thumb: - use areg-
+       ister for reviewing and reconciling real-world asset/liability accounts
+       - use register for reviewing detailed revenues/expenses.
+
+       aregister requires one argument: the account to  report  on.   You  can
+       write  either  the  full  account  name,  or a case-insensitive regular
+       expression which will select the alphabetically first matched  account.
+       (Eg  if  you have assets:aaa:checking and assets:bbb:checking accounts,
+       hledger areg checking would select assets:aaa:checking.)
+
+       Transactions involving subaccounts of this account will also be  shown.
+       aregister  ignores depth limits, so its final total will always match a
+       balance report with similar arguments.
+
+       Any additional arguments form a query which will  filter  the  transac-
+       tions shown.  Note some queries will disturb the running balance, caus-
+       ing it to be different from the account's real-world running balance.
+
+       An example: this shows the transactions and historical running  balance
+       during july, in the first account whose name contains "checking":
+
+              $ hledger areg checking date:jul
+
+       Each aregister line item shows:
+
+       o the  transaction's date (or the relevant posting's date if different,
+         see below)
+
+       o the names of all the other account(s) involved  in  this  transaction
+         (probably abbreviated)
+
+       o the total change to this account's balance from this transaction
+
+       o the account's historical running balance after this transaction.
+
+       Transactions  making a net change of zero are not shown by default; add
+       the -E/--empty flag to show them.
+
+       This command also supports the output  destination  and  output  format
+       options.  The output formats supported are txt, csv, and json.
+
+   aregister and custom posting dates
+       Transactions  whose  date  is  outside  the  report period can still be
+       shown, if they have a posting to this account dated inside  the  report
+       period.   (And  in this case it's the posting date that is shown.) This
+       ensures that aregister can show an accurate historical running balance,
+       matching the one shown by register -H with the same arguments.
+
+       To  filter  strictly  by  transaction date instead, add the --txn-dates
+       flag.  If you use this flag and  some  of  your  postings  have  custom
+       dates, it's probably best to assume the running balance is wrong.
+
+   balance
+       balance, bal
+       Show accounts and their balances.
+
+       balance  is  one  of  hledger's oldest and most versatile commands, for
+       listing account balances, balance changes, values,  value  changes  and
+       more, during one time period or many.  Generally it shows a table, with
+       rows representing accounts, and columns representing periods.
+
+       Note there are some higher-level variants of the balance  command  with
+       convenient  defaults,  which  can be simpler to use: balancesheet, bal-
+       ancesheetequity, cashflow and incomestatement.  When you need more con-
+       trol, then use balance.
+
+   balance features
+       Here's  a quick overview of the balance command's features, followed by
+       more detailed descriptions and examples.  Many of these work  with  the
+       higher-level commands as well.
+
+       balance can show..
+
+       o accounts as a list (-l) or a tree (-t)
+
+       o optionally depth-limited (-[1-9])
+
+       o sorted by declaration order and name, or by amount
+
+       ..and their..
+
+       o balance changes (the default)
+
+       o or actual and planned balance changes (--budget)
+
+       o or value of balance changes (-V)
+
+       o or change of balance values (--valuechange)
+
+       ..in..
+
+       o one time period (the whole journal period by default)
+
+       o or multiple periods (-D, -W, -M, -Q, -Y, -p INTERVAL)
+
+       ..either..
+
+       o per period (the default)
+
+       o or accumulated since report start date (--cumulative)
+
+       o or accumulated since account creation (--historical/-H)
+
+       ..possibly converted to..
+
+       o cost (--value=cost[,COMM]/--cost/-B)
+
+       o or market value, as of transaction dates (--value=then[,COMM])
+
+       o or at period ends (--value=end[,COMM])
+
+       o or now (--value=now)
+
+       o or at some other date (--value=YYYY-MM-DD)
+
+       ..with..
+
+       o totals   (-T),   averages   (-A),  percentages  (-%),  inverted  sign
+         (--invert)
+
+       o rows and columns swapped (--transpose)
+
+       o another field used as account name (--pivot)
+
+       o custom-formatted line items (single-period reports only) (--format)
+
+       This command supports the output destination and output format options,
+       with  output  formats  txt, csv, json, and (multi-period reports only:)
+       html.  In txt output in a colour-supporting terminal, negative  amounts
+       are shown in red.
+
+   Simple balance report
+       With  no  arguments,  balance  shows  a  list of all accounts and their
+       change of balance - ie, the sum of posting amounts,  both  inflows  and
+       outflows  -  during  the  entire period of the journal.  For real-world
+       accounts, this should also match their end balance at the  end  of  the
+       journal period (more on this below).
+
+       Accounts  are  sorted  by declaration order if any, and then alphabeti-
+       cally by account name.  For instance, using examples/sample.journal:
+
+              $ hledger bal
+                                $1  assets:bank:saving
+                               $-2  assets:cash
+                                $1  expenses:food
+                                $1  expenses:supplies
+                               $-1  income:gifts
+                               $-1  income:salary
+                                $1  liabilities:debts
+              --------------------
+                                 0
+
+       Accounts with a zero balance (and no non-zero subaccounts, in tree mode
+       -  see  below)  are  hidden  by  default.   Use -E/--empty to show them
+       (revealing assets:bank:checking here):
+
+              $ hledger -f examples/sample.journal  bal  -E
+                                 0  assets:bank:checking
+                                $1  assets:bank:saving
+                               $-2  assets:cash
+                                $1  expenses:food
+                                $1  expenses:supplies
+                               $-1  income:gifts
+                               $-1  income:salary
+                                $1  liabilities:debts
+              --------------------
+                                 0
+
+       The total of the amounts displayed is shown as the  last  line,  unless
+       -N/--no-total is used.
+
+   Filtered balance report
+       You  can  show  fewer  accounts,  a  different time period, totals from
+       cleared transactions only, etc.  by using query arguments or options to
+       limit the postings being matched.  Eg:
+
+              $ hledger bal --cleared assets date:200806
+                               $-2  assets:cash
+              --------------------
+                               $-2
+
+   List or tree mode
+       By  default,  or with -l/--flat, accounts are shown as a flat list with
+       their full names visible, as in the examples above.
+
+       With -t/--tree, the  account  hierarchy  is  shown,  with  subaccounts'
+       "leaf" names indented below their parent:
+
+              $ hledger balance
+                               $-1  assets
+                                $1    bank:saving
+                               $-2    cash
+                                $2  expenses
+                                $1    food
+                                $1    supplies
+                               $-2  income
+                               $-1    gifts
+                               $-1    salary
+                                $1  liabilities:debts
+              --------------------
+                                 0
+
+       Notes:
+
+       o "Boring" accounts are combined with their subaccount for more compact
+         output, unless --no-elide is used.  Boring accounts have  no  balance
+         of  their own and just one subaccount (eg assets:bank and liabilities
+         above).
+
+       o All balances shown are "inclusive", ie including  the  balances  from
+         all  subaccounts.   Note  this  means  some repetition in the output,
+         which requires explanation when sharing reports with non-plaintextac-
+         counting-users.   A  tree mode report's final total is the sum of the
+         top-level balances shown, not of all the balances shown.
+
+       o Each group of sibling accounts (ie, under a common parent) is  sorted
+         separately.
+
+   Depth limiting
+       With  a depth:N query, or --depth N option, or just -N, balance reports
+       will show accounts only to the specified depth, hiding the deeper  sub-
+       accounts.   Account balances at the depth limit always include the bal-
+       ances from any hidden subaccounts (even in list  mode).   This  can  be
+       useful for getting an overview.  Eg, limiting to depth 1:
+
+              $ hledger balance -N -1
+                               $-1  assets
+                                $2  expenses
+                               $-2  income
+                                $1  liabilities
+
+       You  can  also hide top-level account name parts, using --drop N.  This
+       can be useful for hiding repetitive top-level account names:
+
+              $ hledger bal expenses --drop 1
+                                $1  food
+                                $1  supplies
+              --------------------
+                                $2
+
+
+   Multi-period balance report
+       With  a  report  interval  (set   by   the   -D/--daily,   -W/--weekly,
+       -M/--monthly,  -Q/--quarterly,  -Y/--yearly, or -p/--period flag), bal-
+       ance shows a tabular report, with columns representing successive  time
+       periods (and a title):
+
+              $ hledger balance --quarterly income expenses -E
+              Balance changes in 2008:
+
+                                 ||  2008q1  2008q2  2008q3  2008q4
+              ===================++=================================
+               expenses:food     ||       0      $1       0       0
+               expenses:supplies ||       0      $1       0       0
+               income:gifts      ||       0     $-1       0       0
+               income:salary     ||     $-1       0       0       0
+              -------------------++---------------------------------
+                                 ||     $-1      $1       0       0
+
+       Notes:
+
+       o The report's start/end dates will be expanded, if necessary, to fully
+         encompass the displayed subperiods (so that the first and last subpe-
+         riods have the same duration as the others).
+
+       o Leading  and trailing periods (columns) containing all zeroes are not
+         shown, unless -E/--empty is used.
+
+       o Accounts  (rows)  containing  all  zeroes  are  not   shown,   unless
+         -E/--empty is used.
+
+       o Amounts  with  many commodities are shown in abbreviated form, unless
+         --no-elide is used.  (experimental)
+
+       o Average and/or total columns can be added with the  -A/--average  and
+         -T/--row-total flags.
+
+       o The --transpose flag can be used to exchange rows and columns.
+
+       o The  --pivot  FIELD option causes a different transaction field to be
+         used as "account name".  See PIVOTING.
+
+       Multi-period reports with many periods can be too wide for easy viewing
+       in the terminal.  Here are some ways to handle that:
+
+       o Hide the totals row with -N/--no-total
+
+       o Convert to a single currency with -V
+
+       o Maximize the terminal window
+
+       o Reduce the terminal's font size
+
+       o View  with  a  pager like less, eg: hledger bal -D --color=yes | less
+         -RS
+
+       o Output as CSV and use a CSV viewer like visidata (hledger bal  -D  -O
+         csv  |  vd  -f  csv),  Emacs'  csv-mode (M-x csv-mode, C-c C-a), or a
+         spreadsheet (hledger bal -D -o a.csv && open a.csv)
+
+       o Output as HTML and view with a browser: hledger bal -D -o  a.html  &&
+         open a.html
+
+   Sorting by amount
+       With  -S/--sort-amount,  accounts with the largest (most positive) bal-
+       ances are shown first.  Eg: hledger bal expenses -MAS shows  your  big-
+       gest averaged monthly expenses first.
+
+       Revenues  and liability balances are typically negative, however, so -S
+       shows these in reverse  order.   To  work  around  this,  you  can  add
+       --invert  to flip the signs.  (Or, use one of the higher-level reports,
+       which flip the sign automatically.  Eg: hledger incomestatement  -MAS).
+
+
+   Percentages
+       With  -%/--percent, balance reports show each account's value expressed
+       as a percentage of the (column) total:
+
+              $ hledger bal expenses -Q -%
+              Balance changes in 2008:
+
+                                 || 2008Q1   2008Q2  2008Q3  2008Q4
+              ===================++=================================
+               expenses:food     ||      0   50.0 %       0       0
+               expenses:supplies ||      0   50.0 %       0       0
+              -------------------++---------------------------------
+                                 ||      0  100.0 %       0       0
+
+       Note it is not useful to calculate percentages if the amounts in a col-
+       umn  have  mixed  signs.  In this case, make a separate report for each
+       sign, eg:
+
+              $ hledger bal -% amt:`>0`
+              $ hledger bal -% amt:`<0`
+
+       Similarly, if the amounts in a column have mixed  commodities,  convert
+       them  to  one  commodity with -B, -V, -X or --value, or make a separate
+       report for each commodity:
+
+              $ hledger bal -% cur:\\$
+              $ hledger bal -% cur:EUR
+
+   Balance change, end balance
+       It's important to be clear on the meaning of the numbers shown in  bal-
+       ance reports.  Here is some terminology we use:
+
+       A  balance  change  is  the  net  amount  added to, or removed from, an
+       account during some period.
+
+       An end balance is the amount accumulated in an account as of some  date
+       (and  some  time,  but hledger doesn't store that; assume end of day in
+       your timezone).  It is the sum of previous balance changes.
+
+       We call it a historical end balance if it includes all balance  changes
+       since the account was created.  For a real world account, this means it
+       will match the "historical record", eg the balances  reported  in  your
+       bank statements or bank web UI.  (If they are correct!)
+
+       In  general,  balance  changes  are what you want to see when reviewing
+       revenues and expenses, and historical end balances are what you want to
+       see when reviewing or reconciling asset, liability and equity accounts.
+
+       balance shows balance changes by default.  To see  accurate  historical
+       end balances:
+
+       1. Initialise  account  starting  balances  with  an "opening balances"
+          transaction (a transfer from equity  to  the  account),  unless  the
+          journal covers the account's full lifetime.
+
+       2. Include all of of the account's prior postings in the report, by not
+          specifying a report start date,  or  by  using  the  -H/--historical
+          flag.  (-H causes report start date to be ignored when summing post-
+          ings.)
+
+   Balance report types
+       For more flexible reporting, there are three important option groups:
+
+       hledger balance  [CALCULATIONTYPE]  [ACCUMULATIONTYPE]  [VALUATIONTYPE]
+       ...
+
+       The  first  two  are  the  most important: calculation type selects the
+       basic calculation to perform for each table  cell,  while  accumulation
+       type says which postings should be included in each cell's calculation.
+       Typically one or both of these are selected by default,  so  you  don't
+       need  to  write  them explicitly.  A valuation type can be added if you
+       want to convert the basic report to value or cost.
+
+       Calculation type:
+       The basic calculation to perform for each table cell.  It is one of:
+
+       o --sum : sum the posting amounts (default)
+
+       o --budget : like --sum but also show a goal amount
+
+       o --valuechange : show the change in period-end historical balance val-
+         ues
+
+       Accumulation type:
+       Which  postings  should  be included in each cell's calculation.  It is
+       one of:
+
+       o --change : postings from column start to column end,  ie  within  the
+         cell's  period.   Typically  used to see revenues/expenses.  (default
+         for balance, incomestatement)
+
+       o --cumulative : postings from report start to column end, eg  to  show
+         changes accumulated since the report's start date.  Rarely used.
+
+       o --historical/-H  :  postings from journal start to column end, ie all
+         postings from account creation to the end of the cell's period.  Typ-
+         ically  used  to  see  historical  end  balances  of  assets/liabili-
+         ties/equity.  (default for  balancesheet,  balancesheetequity,  cash-
+         flow)
+
+       Valuation type:
+       Which kind of valuation, valuation date(s) and optionally a target val-
+       uation commodity to use.  It is one of:
+
+       o no valuation, show amounts in their original commodities (default)
+
+       o --value=cost[,COMM] : no valuation, show amounts converted to cost
+
+       o --value=then[,COMM] : show value at transaction dates
+
+       o --value=end[,COMM] : show value at period end date(s)  (default  with
+         --valuechange)
+
+       o --value=now[,COMM] : show value at today's date
+
+       o --value=YYYY-MM-DD[,COMM] : show value at another date
+
+       or one of their aliases: --cost/-B, --market/-V or --exchange/-X.
+
+       Most  combinations  of these options should produce reasonable reports,
+       but if you find any that seem wrong or misleading, let  us  know.   The
+       following restrictions are applied:
+
+       o --valuechange implies --value=end
+
+       o --valuechange  makes  --change  the  default  when used with the bal-
+         ancesheet/balancesheetequity commands
+
+       o --cumulative or --historical disables --row-total/-T
+
+       For reference, here is what the combinations of accumulation and valua-
+       tion show:
+
+
+       Valua-     no valuation       --value= then       --value= end       --value= YYYY-

+   Useful balance reports
+       Some frequently used balance options/reports are:
+
+       o bal -M revenues expenses
+       Show  revenues/expenses  in each month.  Also available as the incomes-
+       tatement command.
+
+       o bal -M -H assets liabilities
+       Show historical asset/liability  balances  at  each  month  end.   Also
+       available as the balancesheet command.
+
+       o bal -M -H assets liabilities equity
+       Show  historical  asset/liability/equity  balances  at  each month end.
+       Also available as the balancesheetequity command.
+
+       o bal -M assets not:receivable
+       Show changes to liquid assets in each month.   Also  available  as  the
+       cashflow command.
+
+       Also:
+
+       o bal -M expenses -2 -SA
+       Show  monthly  expenses  summarised  to  depth  2 and sorted by average
+       amount.
+
+       o bal -M --budget expenses
+       Show monthly expenses and budget goals.
+
+       o bal -M --valuechange investments
+       Show monthly change in market value of investment assets.
+
+       o bal  investments  --valuechange  -D  date:lastweek  amt:'>1000'  -STA
+         [--invert]
+       Show top gainers [or losers] last week
+
+   Budget report
+       The  --budget  report  type  activates extra columns showing any budget
+       goals for each account and period.  The budget  goals  are  defined  by
+       periodic  transactions.   This is very useful for comparing planned and
+       actual income, expenses, time usage, etc.
+
+       For example, you can  take  average  monthly  expenses  in  the  common
+       expense categories to construct a minimal monthly budget:
+
+              ;; Budget
+              ~ monthly
+                income  $2000
+                expenses:food    $400
+                expenses:bus     $50
+                expenses:movies  $30
+                assets:bank:checking
+
+              ;; Two months worth of expenses
+              2017-11-01
+                income  $1950
+                expenses:food    $396
+                expenses:bus     $49
+                expenses:movies  $30
+                expenses:supplies  $20
+                assets:bank:checking
+
+              2017-12-01
+                income  $2100
+                expenses:food    $412
+                expenses:bus     $53
+                expenses:gifts   $100
+                assets:bank:checking
+
+       You can now see a monthly budget report:

+
+       This is different from a normal balance report in several ways:
+
+       o Only  accounts  with budget goals during the report period are shown,
+         by default.
+
+       o In each column, in square brackets after the  actual  amount,  budget
+         goal  amounts are shown, and the actual/goal percentage.  (Note: bud-
+         get goals should be in the same commodity as the actual amount.)
+
+       o All parent accounts are always shown, even in list mode.  Eg  assets,
+         assets:bank, and expenses above.
+
+       o Amounts  always include all subaccounts, budgeted or unbudgeted, even
+         in list mode.
+
+       This means that the numbers displayed will not always add up! Eg above,
+       the  expenses  actual  amount  includes the gifts and supplies transac-
+       tions, but the expenses:gifts and expenses:supplies  accounts  are  not
+       shown, as they have no budget amounts declared.
+
+       This  can  be confusing.  When you need to make things clearer, use the
+       -E/--empty flag, which will reveal all  accounts  including  unbudgeted
+       ones, giving the full picture.  Eg:
+
+              $ hledger balance -M --budget --empty

+
+   Budget report start date
+       This  might  be  a bug, but for now: when making budget reports, it's a
+       good idea to explicitly set the report's start date to the first day of
+       a  reporting  period,  because a periodic rule like ~ monthly generates
+       its transactions on the 1st of each month, and if your journal  has  no
+       regular  transactions  on  the 1st, the default report start date could
+       exclude that budget goal, which can be a little  surprising.   Eg  here
+       the default report period is just the day of 2020-01-15:
+
+              ~ monthly in 2020
+                (expenses:food)  $500
+
+              2020-01-15
+                expenses:food    $400
+                assets:checking
+
+              $ hledger bal expenses --budget

+
+       To  avoid  this,  specify  the  budget report's period, or at least the
+       start date, with -b/-e/-p/date:, to ensure it includes the budget  goal
+       transactions  (periodic  transactions)  that  you  want.  Eg, adding -b
+       2020/1/1 to the above:
+
+              $ hledger bal expenses --budget -b 2020/1/1

+
+   Nested budgets
+       You can add budgets to any account in your account hierarchy.   If  you
+       have budgets on both parent account and some of its children, then bud-
+       get(s) of the child account(s) would be added to the  budget  of  their
+       parent, much like account balances behave.
+
+       In  the  most  simple case this means that once you add a budget to any
+       account, all its parents would have budget as well.
+
+       To illustrate this, consider the following budget:
+
+              ~ monthly from 2019/01
+                  expenses:personal             $1,000.00
+                  expenses:personal:electronics    $100.00
+                  liabilities
+
+       With this, monthly budget for electronics is defined  to  be  $100  and
+       budget  for  personal expenses is an additional $1000, which implicitly
+       means that budget for both expenses:personal and expenses is $1100.
+
+       Transactions in  expenses:personal:electronics  will  be  counted  both
+       towards  its  $100 budget and $1100 of expenses:personal , and transac-
+       tions in any other subaccount of  expenses:personal  would  be  counted
+       towards only towards the budget of expenses:personal.
+
+       For example, let's consider these transactions:
+
+              ~ monthly from 2019/01
+                  expenses:personal             $1,000.00
+                  expenses:personal:electronics    $100.00
+                  liabilities
+
+              2019/01/01 Google home hub
+                  expenses:personal:electronics          $90.00
+                  liabilities                           $-90.00
+
+              2019/01/02 Phone screen protector
+                  expenses:personal:electronics:upgrades          $10.00
+                  liabilities
+
+              2019/01/02 Weekly train ticket
+                  expenses:personal:train tickets       $153.00
+                  liabilities
+
+              2019/01/03 Flowers
+                  expenses:personal          $30.00
+                  liabilities
+
+       As  you  can  see,  we have transactions in expenses:personal:electron-
+       ics:upgrades and expenses:personal:train tickets,  and  since  both  of
+       these  accounts  are  without explicitly defined budget, these transac-

+   Customising single-period balance reports
+       For single-period balance reports displayed in the terminal (only), you
+       can  use --format FMT to customise the format and content of each line.
+       Eg:
+
+              $ hledger balance --format "%20(account) %12(total)"
+                            assets          $-1
+                       bank:saving           $1
+                              cash          $-2
+                          expenses           $2
+                              food           $1
+                          supplies           $1

+
+       The FMT format string (plus a newline) specifies the formatting applied
+       to  each  account/balance pair.  It may contain any suitable text, with
+       data fields interpolated like so:
+
+       %[MIN][.MAX](FIELDNAME)
+
+       o MIN pads with spaces to at least this width (optional)
+
+       o MAX truncates at this width (optional)
+
+       o FIELDNAME must be enclosed in parentheses, and can be one of:
+
+         o depth_spacer - a number of spaces equal to the account's depth,  or
+           if MIN is specified, MIN * depth spaces.
+
+         o account - the account's name
+
+         o total - the account's balance/posted total, right justified
+
+       Also,  FMT  can begin with an optional prefix to control how multi-com-
+       modity amounts are rendered:
+
+       o %_ - render on multiple lines, bottom-aligned (the default)
+
+       o %^ - render on multiple lines, top-aligned
+
+       o %, - render on one line, comma-separated
+
+       There are some quirks.  Eg in one-line  mode,  %(depth_spacer)  has  no
+       effect,  instead  %(account) has indentation built in.  Experimentation
+       may be needed to get pleasing results.
+
+       Some example formats:
+
+       o %(total) - the account's total
+
+       o %-20.20(account) - the account's name, left justified, padded  to  20
+         characters and clipped at 20 characters
+
+       o %,%-50(account)   %25(total)  - account name padded to 50 characters,
+         total padded to 20 characters, with multiple commodities rendered  on
+         one line
+
+       o %20(total)   %2(depth_spacer)%-(account) - the default format for the
+         single-column balance report
+
+   balancesheet
+       balancesheet, bs
+       This command displays a balance sheet, showing historical  ending  bal-

+
+   check
+       check
+       Check for various kinds of errors in your data.
+
+       hledger  provides  a  number  of  built-in error checks to help prevent
+       problems in your data.  Some of these are run  automatically;  or,  you
+       can  use this check command to run them on demand, with no output and a
+       zero exit code if all is well.  Specify their names (or  a  prefix)  as
+       argument(s).
+
+       Some examples:
+
+              hledger check      # basic checks
+              hledger check -s   # basic + strict checks
+              hledger check ordereddates payees  # basic + two other checks
+
+       Here are the checks currently available:
+
+   Basic checks
+       These checks are always run automatically, by (almost) all hledger com-
+       mands, including check:
+
+       o parseable - data files are well-formed and can be successfully parsed
+
+       o balancedwithautoconversion - all transactions are balanced, inferring
+         missing amounts where necessary, and possibly converting  commodities
+         using transaction prices or automatically-inferred transaction prices
+
+       o assertions - all balance  assertions  in  the  journal  are  passing.
+         (This check can be disabled with -I/--ignore-assertions.)
+
+   Strict checks
+       These additional checks are run when the -s/--strict (strict mode) flag
+       is used.  Or, they can be run by giving their  names  as  arguments  to
+       check:
+
+       o accounts - all account names used by transactions have been declared
+
+       o commodities - all commodity symbols used have been declared
+
+       o balancednoautoconversion  - transactions are balanced, possibly using
+         explicit transaction prices but not inferred ones
+
+   Other checks
+       These checks can be run only by giving  their  names  as  arguments  to
+       check.   They  are  more  specialised  and  not desirable for everyone,
+       therefore optional:
+
+       o ordereddates - transactions are ordered by date within each file
+
+       o payees - all payees used by transactions have been declared
+
+       o uniqueleafnames - all account leaf names are unique
+
+   Custom checks
+       A few more checks are are available as  separate  add-on  commands,  in
+       https://github.com/simonmichael/hledger/tree/master/bin:
+
+       o hledger-check-tagfiles  -  all  tag  values  containing  / (a forward
+         slash) exist as file paths
+
+       o hledger-check-fancyassertions - more complex balance  assertions  are
+         passing
+
+       You could make similar scripts to perform your own custom checks.  See:
+       Cookbook -> Scripting.
+
+   close
+       close, equity
+       Prints a "closing  balances"  transaction  and  an  "opening  balances"
+       transaction that bring account balances to and from zero, respectively.
+       These can be added to your journal file(s), eg to bring asset/liability
+       balances  forward  into  a  new  journal  file,  or  to  close out rev-
+       enues/expenses to retained earnings at the end of a period.
+
+       You can print just one of these transactions by using  the  --close  or
+       --open  flag.   You  can customise their descriptions with the --close-
+       desc and --open-desc options.
+
+       One amountless posting to "equity:opening/closing balances" is added to
+       balance  the  transactions, by default.  You can customise this account
+       name with --close-acct and --open-acct; if  you  specify  only  one  of
+       these, it will be used for both.
+
+       With --x/--explicit, the equity posting's amount will be shown.  And if
+       it involves multiple commodities, a posting for each commodity will  be
+       shown, as with the print command.
+
+       With  --interleaved, the equity postings are shown next to the postings
+       they balance, which makes troubleshooting easier.
+
+       By default, transaction prices in the journal are ignored when generat-
+       ing  the  closing/opening  transactions.   With --show-costs, this cost
+       information is preserved (balance -B reports will  be  unchanged  after
+       the transition).  Separate postings are generated for each cost in each
+       commodity.  Note this can generate very large journal entries,  if  you
+       have many foreign currency or investment transactions.
+
+   close usage
+       If you split your journal files by time (eg yearly), you will typically
+       run this command at the end of the year, and save the closing  transac-
+       tion  as last entry of the old file, and the opening transaction as the
+       first entry of the new file.  This makes the files self  contained,  so
+       that  correct balances are reported no matter which of them are loaded.
+       Ie, if you load just one file, the balances are initialised  correctly;
+       or  if  you  load several files, the redundant closing/opening transac-
+       tions cancel each other out.  (They will show up in print  or  register
+       reports;  you  can  exclude  them  with  a  query like not:desc:'(open-
+       ing|closing) balances'.)
+
+       If you're running a business, you might also use this command to "close
+       the  books"  at  the  end  of an accounting period, transferring income
+       statement account balances to retained  earnings.   (You  may  want  to
+       change the equity account name to something like "equity:retained earn-
+       ings".)
+
+       By default, the closing transaction is dated  yesterday,  the  balances
+       are  calculated  as of end of yesterday, and the opening transaction is
+       dated today.  To close on some other date, use: hledger close -e  OPEN-
+       INGDATE.   Eg,  to  close/open  on the 2018/2019 boundary, use -e 2019.
+       You can also use -p or date:PERIOD (any starting date is ignored).
+
+       Both   transactions   will   include   balance   assertions   for   the
+       closed/reopened  accounts.   You probably shouldn't use status or real-
+       ness filters (like -C or -R or status:) with this command, or the  gen-
+       erated balance assertions will depend on these flags.  Likewise, if you
+       run this command with --auto,  the  balance  assertions  will  probably
+       always require --auto.
+
+       Examples:
+
+       Carrying asset/liability balances into a new file for 2019:
+
+              $ hledger close -f 2018.journal -e 2019 assets liabilities --open
+                  # (copy/paste the output to the start of your 2019 journal file)
+              $ hledger close -f 2018.journal -e 2019 assets liabilities --close
+                  # (copy/paste the output to the end of your 2018 journal file)
+
+       Now:
+
+              $ hledger bs -f 2019.journal                   # one file - balances are correct
+              $ hledger bs -f 2018.journal -f 2019.journal   # two files - balances still correct
+              $ hledger bs -f 2018.journal not:desc:closing  # to see year-end balances, must exclude closing txn
+
+       Transactions spanning the closing date can complicate matters, breaking
+       balance assertions:
+
+              2018/12/30 a purchase made in 2018, clearing the following year
+                  expenses:food          5
+                  assets:bank:checking  -5  ; [2019/1/2]
+
+       Here's one way to resolve that:
+
+              ; in 2018.journal:
+              2018/12/30 a purchase made in 2018, clearing the following year
+                  expenses:food          5
+                  liabilities:pending
+
+              ; in 2019.journal:
+              2019/1/2 clearance of last year's pending transactions
+                  liabilities:pending    5 = 0
+                  assets:checking
+
+   codes
+       codes
+       List the codes seen in transactions, in the order parsed.
+
+       This command prints the value of each transaction's code field, in  the
+       order  transactions  were  parsed.  The transaction code is an optional
+       value written in parentheses between the date  and  description,  often
+       used to store a cheque number, order number or similar.
+
+       Transactions aren't required to have a code, and missing or empty codes
+       will not be shown by default.  With the -E/--empty flag, they  will  be
+       printed as blank lines.
+
+       You can add a query to select a subset of transactions.
+
+       Examples:
+
+              1/1 (123)
+               (a)  1
+
+              1/1 ()
+               (a)  1
+
+              1/1
+               (a)  1
+
+              1/1 (126)
+               (a)  1
+
+              $ hledger codes
+              123
+              124
+              126
+
+              $ hledger codes -E
+              123
+              124
+
+
+              126
+
+   commodities
+       commodities
+       List all commodity/currency symbols used or declared in the journal.
+
+   descriptions
+       descriptions
+       List the unique descriptions that appear in transactions.
+
+       This command lists the unique descriptions that appear in transactions,
+       in alphabetic order.  You can add a query to select a subset of  trans-
+       actions.
+
+       Example:
+
+              $ hledger descriptions
+              Store Name
+              Gas Station | Petrol
+              Person A
+
+   diff
+       diff
+       Compares  a  particular  account's transactions in two input files.  It
+       shows any transactions to this account which are in one file but not in
+       the other.
+
+       More precisely, for each posting affecting this account in either file,
+       it looks for a corresponding posting in the other file which posts  the
+       same  amount  to  the  same  account (ignoring date, description, etc.)
+       Since postings not transactions are compared, this also works when mul-
+       tiple bank transactions have been combined into a single journal entry.
+
+       This is useful eg if you have downloaded an account's transactions from
+       your  bank (eg as CSV data).  When hledger and your bank disagree about
+       the account balance, you can compare the bank data with your journal to
+       find out the cause.
+
+       Examples:
+
+              $ hledger diff -f $LEDGER_FILE -f bank.csv assets:bank:giro
+              These transactions are in the first file only:
+
+              2014/01/01 Opening Balances
+                  assets:bank:giro              EUR ...
+                  ...
+                  equity:opening balances       EUR -...
+
+              These transactions are in the second file only:
+
+   files
+       files
+       List  all  files  included in the journal.  With a REGEX argument, only
+       file names matching the regular expression (case sensitive) are  shown.
+
+   help
+       help
+       Show  the  hledger  user  manual  in one of several formats, optionally
+       positioned at a given TOPIC (if possible).  TOPIC is  any  heading,  or
+       heading  prefix,  in the manual.  Some examples: commands, print, 'auto
+       postings', periodic.
+
+       This command shows the user manual built in to  this  hledger  version.
+       It  can  be useful if the correct version of the hledger manual, or the
+       usual viewing tools, are not installed on your system.
+
+       By default it uses the best viewer it can find in $PATH, in this order:
+       info, man, $PAGER (unless a topic is specified), less, or stdout.  When
+       run non-interactively, it always uses stdout.  Or you can select a par-
+       ticular viewer with the -i (info), -m (man), or -p (pager) flags.
+
+   import
+       import
+       Read  new  transactions added to each FILE since last run, and add them
+       to the main journal file.  Or with --dry-run, just print  the  transac-
+       tions  that  would  be  added.  Or with --catchup, just mark all of the
+       FILEs' transactions as imported, without actually importing any.
+
+       Unlike other hledger commands, with import the journal file is an  out-
+       put file, and will be modified, though only by appending (existing data
+       will not be changed).  The input files are specified as  arguments,  so
+       to  import  one  or  more  CSV files to your main journal, you will run
+       hledger import bank.csv or perhaps hledger import *.csv.
+
+       Note you can import from any file format, though CSV files are the most
+       common import source, and these docs focus on that case.
+
+   Deduplication
+       As  a convenience import does deduplication while reading transactions.
+       This does not mean "ignore transactions that look the same", but rather
+       "ignore transactions that have been seen before".  This is intended for
+       when you are periodically importing  foreign  data  which  may  contain
+       already-imported  transactions.   So eg, if every day you download bank
+       CSV files containing redundant data, you can safely run hledger  import
+       bank.csv  and only new transactions will be imported.  (import is idem-
+       potent.)
+
+       Since the items being read (CSV records, eg) often  do  not  come  with
+       unique  identifiers, hledger detects new transactions by date, assuming
+       that:
+
+       1. new items always have the newest dates
+
+       2. item dates do not change across reads
+
+       3. and items with the same date  remain  in  the  same  relative  order
+          across reads.
+
+       These  are  often  true of CSV files representing transactions, or true
+       enough so that it works pretty well in practice.  1 is  important,  but
+       violations of 2 and 3 amongst the old transactions won't matter (and if
+       you import often, the new transactions will be few, so less  likely  to
+       be the ones affected).
+
+       hledger  remembers the latest date processed in each input file by sav-
+       ing a hidden ".latest" state file in the same directory.  Eg when read-
+       ing  finance/bank.csv,  it  will  look for and update the finance/.lat-
+       est.bank.csv state file.  The format is simple: one or more lines  con-
+       taining  the  same  ISO-format  date (YYYY-MM-DD), meaning "I have pro-
+       cessed transactions up to this date, and this  many  of  them  on  that
+       date." Normally you won't see or manipulate these state files yourself.
+       But if needed, you can delete them  to  reset  the  state  (making  all
+       transactions  "new"), or you can construct them to "catch up" to a cer-
+       tain date.
+
+       Note deduplication (and updating of state files) can also  be  done  by
+       print --new, but this is less often used.
+
+   Import testing
+       With  --dry-run,  the transactions that will be imported are printed to
+       the terminal, without updating your journal or state files.  The output
+       is  valid  journal  format, like the print command, so you can re-parse
+       it.  Eg, to see any importable transactions which CSV  rules  have  not
+       categorised:
+
+              $ hledger import --dry bank.csv | hledger -f- -I print unknown
+
+       or (live updating):
+
+              $ ls bank.csv* | entr bash -c 'echo ====; hledger import --dry bank.csv | hledger -f- -I print unknown'
+
+   Importing balance assignments
+       Entries  added  by import will have their posting amounts made explicit
+       (like hledger print -x).  This means that any  balance  assignments  in
+       imported  files must be evaluated; but, imported files don't get to see
+       the main file's account balances.  As a result, importing entries  with
+       balance assignments (eg from an institution that provides only balances
+       and not posting  amounts)  will  probably  generate  incorrect  posting
+       amounts.  To avoid this problem, use print instead of import:
+
+              $ hledger print IMPORTFILE [--new] >> $LEDGER_FILE
+
+       (If  you  think  import  should leave amounts implicit like print does,
+       please test it and send a pull request.)
+
+   Commodity display styles
+       Imported amounts will be formatted according to the canonical commodity
+       styles (declared or inferred) in the main journal file.
+
+   incomestatement
+       incomestatement, is
+
+       This  command  displays  an  income  statement,  showing  revenues  and
+       expenses during one or more periods.  Amounts  are  shown  with  normal
+       positive sign, as in conventional financial statements.
+
+       The revenue and expense accounts shown are those accounts declared with
+       the Revenue or Expense type, or otherwise all  accounts  under  a  top-
+       level  revenue  or income or expense account (case insensitive, plurals
+       allowed).
+
+       Example:
+
+              $ hledger incomestatement
+              Income Statement
+
+              Revenues:
+                               $-2  income
+                               $-1    gifts
+                               $-1    salary
+              --------------------
+                               $-2
+
+              Expenses:
+                                $2  expenses
+                                $1    food
+                                $1    supplies
+              --------------------
+                                $2
+
+              Total:
+              --------------------
+                                 0
+
+       This command is a higher-level variant of the balance command, and sup-
+       ports  many  of  that command's features, such as multi-period reports.
+       It is similar to hledger balance '(revenues|income)' expenses, but with
+       smarter  account  detection,  and  revenues/income displayed with their
+       sign flipped.
+
+       This command also supports the output  destination  and  output  format
+       options  The  output formats supported are txt, csv, html, and (experi-
+       mental) json.
+
+   notes
+       notes
+       List the unique notes that appear in transactions.
+
+       This command lists the unique notes that  appear  in  transactions,  in
+       alphabetic  order.   You can add a query to select a subset of transac-
+       tions.  The note is the part of the transaction description after  a  |
+       character (or if there is no |, the whole description).
+
+       Example:
+
+              $ hledger notes
+              Petrol
+              Snacks
+
+   payees
+       payees
+       List the unique payee/payer names that appear in transactions.
+
+       This  command  lists  unique payee/payer names which have been declared
+       with payee directives (--declared), used  in  transaction  descriptions
+       (--used), or both (the default).
+
+       The  payee/payer  is the part of the transaction description before a |
+       character (or if there is no |, the whole description).
+
+       You can add query arguments to select a subset of  transactions.   This
+       implies --used.
+
+       Example:
+
+              $ hledger payees
+              Store Name
+              Gas Station
+              Person A
+
+   prices
+       prices
+       Print  market  price  directives  from the journal.  With --costs, also
+       print synthetic  market  prices  based  on  transaction  prices.   With
+       --inverted-costs,  also  print  inverse  prices  based  on  transaction
+       prices.  Prices (and postings providing prices) can be  filtered  by  a
+       query.  Price amounts are always displayed with their full precision.
+
+   print
+       print
+       Show transaction journal entries, sorted by date.
+
+       The print command displays full journal entries (transactions) from the
+       journal file, sorted by date (or with --date2, by secondary date).
+
+       Amounts are shown mostly normalised to commodity display style, eg  the
+       placement  of commodity symbols will be consistent.  All of their deci-
+       mal places are shown, as in the original journal entry (with one alter-
+       ation: in some cases trailing zeroes are added.)
+
+       Amounts are shown right-aligned within each transaction (but not across
+       all transactions).
+
+       Directives and inter-transaction comments  are  not  shown,  currently.
+       This means the print command is somewhat lossy, and if you are using it
+       to reformat your journal you should take care to  also  copy  over  the
+       directives and file-level comments.
+
+       Eg:
+
+              $ hledger print
+              2008/01/01 income
+                  assets:bank:checking            $1
+                  income:salary                  $-1
+
+              2008/06/01 gift
+                  assets:bank:checking            $1
+                  income:gifts                   $-1
+
+              2008/06/02 save
+                  assets:bank:saving              $1
+                  assets:bank:checking           $-1
+
+              2008/06/03 * eat & shop
+                  expenses:food                $1
+                  expenses:supplies            $1
+                  assets:cash                 $-2
+
+              2008/12/31 * pay off
+                  liabilities:debts               $1
+                  assets:bank:checking           $-1
+
+       print's  output is usually a valid hledger journal, and you can process
+       it again with a second hledger command.  This can be useful for certain
+       kinds of search, eg:
+
+              # Show running total of food expenses paid from cash.
+              # -f- reads from stdin. -I/--ignore-assertions is sometimes needed.
+              $ hledger print assets:cash | hledger -f- -I reg expenses:food
+
+       There are some situations where print's output can become unparseable:
+
+       o Valuation  affects  posting amounts but not balance assertion or bal-
+         ance assignment amounts, potentially causing those to fail.
+
+       o Auto postings can generate postings with too many missing amounts.
+
+       Normally, the journal entry's explicit or implicit amount style is pre-
+       served.  For example, when an amount is omitted in the journal, it will
+       not appear in the output.   Similarly,  when  a  transaction  price  is
+       implied but not written, it will not appear in the output.  You can use
+       the -x/--explicit flag to  make  all  amounts  and  transaction  prices
+       explicit,  which  can  be useful for troubleshooting or for making your
+       journal more readable and robust against data entry errors.  -x is also
+       implied by using any of -B,-V,-X,--value.
+
+       Note,  -x/--explicit  will cause postings with a multi-commodity amount
+       (these can arise when a multi-commodity  transaction  has  an  implicit
+       amount)  to  be  split into multiple single-commodity postings, keeping
+       the output parseable.
+
+       With -B/--cost, amounts with transaction prices are converted  to  cost
+       using that price.  This can be used for troubleshooting.
+
+       With  -m/--match and a STR argument, print will show at most one trans-
+       action: the one one whose description is most similar to  STR,  and  is
+       most  recent.  STR should contain at least two characters.  If there is
+       no similar-enough match, no transaction will be shown.
+
+       With --new, hledger prints only transactions it has not seen on a  pre-
+       vious  run.  This uses the same deduplication system as the import com-
+       mand.  (See import's docs for details.)
+
+       This command also supports the output  destination  and  output  format
+       options  The  output formats supported are txt, csv, and (experimental)
+       json and sql.
+
+       Here's an example of print's CSV output:
+
+              $ hledger print -Ocsv
+              "txnidx","date","date2","status","code","description","comment","account","amount","commodity","credit","debit","posting-status","posting-comment"
+              "1","2008/01/01","","","","income","","assets:bank:checking","1","$","","1","",""
+              "1","2008/01/01","","","","income","","income:salary","-1","$","1","","",""
+              "2","2008/06/01","","","","gift","","assets:bank:checking","1","$","","1","",""
+              "2","2008/06/01","","","","gift","","income:gifts","-1","$","1","","",""
+              "3","2008/06/02","","","","save","","assets:bank:saving","1","$","","1","",""

+
+       o There is one CSV record per posting, with  the  parent  transaction's
+         fields repeated.
+
+       o The "txnidx" (transaction index) field shows which postings belong to
+         the same transaction.  (This number might change if transactions  are
+         reordered  within  the file, files are parsed/included in a different
+         order, etc.)
+
+       o The amount is separated into "commodity" (the  symbol)  and  "amount"
+         (numeric quantity) fields.
+
+       o The numeric amount is repeated in either the "credit" or "debit" col-
+         umn, for convenience.  (Those names are not accurate in the  account-
+         ing  sense;  it  just  puts negative amounts under credit and zero or
+         greater amounts under debit.)
+
+   print-unique
+       print-unique
+       Print transactions which do not reuse an already-seen description.
+
+       Example:
+
+              $ cat unique.journal
+              1/1 test
+               (acct:one)  1
+              2/2 test
+               (acct:two)  2
+              $ LEDGER_FILE=unique.journal hledger print-unique
+              (-f option not supported)
+              2015/01/01 test
+                  (acct:one)             1
+
+   register
+       register, reg
+       Show postings and their running total.
+
+       The register command displays matched postings, across all accounts, in
+       date  order,  with  their  running total or running historical balance.
+       (See also the aregister command, which shows matched transactions in  a
+       specific account.)
+
+       register normally shows line per posting, but note that multi-commodity
+       amounts will occupy multiple lines (one line per commodity).
+
+       It is typically used with a query selecting a  particular  account,  to
+       see that account's activity:
+
+              $ hledger register checking

+
+       With --date2, it shows and sorts by secondary date instead.
+
+       The  --historical/-H  flag  adds the balance from any undisplayed prior
+       postings to the running total.  This is useful when  you  want  to  see
+       only recent activity, with a historically accurate running balance:
+
+              $ hledger register checking -b 2008/6 --historical
+              2008/06/01 gift                 assets:bank:checking            $1           $2

+
+       The --depth option limits the amount of sub-account detail displayed.
+
+       The  --average/-A flag shows the running average posting amount instead
+       of the running total (so, the final number displayed is the average for
+       the  whole  report period).  This flag implies --empty (see below).  It
+       is affected by --historical.  It  works  best  when  showing  just  one
+       account and one commodity.
+
+       The  --related/-r  flag shows the other postings in the transactions of
+       the postings which would normally be shown.
+
+       The --invert flag negates all amounts.  For example, it can be used  on
+       an income account where amounts are normally displayed as negative num-
+       bers.  It's also useful  to  show  postings  on  the  checking  account
+       together with the related account:
+
+              $ hledger register --related --invert assets:checking
+
+       With  a  reporting  interval,  register shows summary postings, one per
+       interval, aggregating the postings to each account:
+
+              $ hledger register --monthly income
+              2008/01                 income:salary                          $-1          $-1
+              2008/06                 income:gifts                           $-1          $-2
+
+       Periods with no activity, and summary postings with a zero amount,  are
+       not shown by default; use the --empty/-E flag to see them:
+
+              $ hledger register --monthly income -E
+              2008/01                 income:salary                          $-1          $-1

+              2008/08                                                          0          $-2

+
+       Often,  you'll  want  to  see  just one line per interval.  The --depth
+       option helps with this, causing subaccounts to be aggregated:
+
+              $ hledger register --monthly assets --depth 1h
+              2008/01                 assets                                  $1           $1
+              2008/06                 assets                                 $-1            0
+              2008/12                 assets                                 $-1          $-1
+
+       Note when using report intervals, if you specify start/end dates  these
+       will  be  adjusted  outward  if  necessary to contain a whole number of
+       intervals.  This ensures that the first and  last  intervals  are  full
+       length and comparable to the others in the report.
+
+   Custom register output
+       register  uses  the  full terminal width by default, except on windows.
+       You can override this by setting the COLUMNS environment variable  (not
+       a bash shell variable) or by using the --width/-w option.
+
+       The  description  and  account columns normally share the space equally
+       (about half of (width - 40) each).  You can adjust  this  by  adding  a
+       description  width  as  part  of  --width's  argument, comma-separated:
+       --width W,D .  Here's a diagram (won't display correctly in --help):
+
+              <--------------------------------- width (W) ---------------------------------->
+              date (10)  description (D)       account (W-41-D)     amount (12)   balance (12)
+              DDDDDDDDDD dddddddddddddddddddd  aaaaaaaaaaaaaaaaaaa  AAAAAAAAAAAA  AAAAAAAAAAAA
+
+       and some examples:
+
+              $ hledger reg                     # use terminal width (or 80 on windows)
+              $ hledger reg -w 100              # use width 100
+              $ COLUMNS=100 hledger reg         # set with one-time environment variable
+              $ export COLUMNS=100; hledger reg # set till session end (or window resize)
+              $ hledger reg -w 100,40           # set overall width 100, description width 40
+              $ hledger reg -w $COLUMNS,40      # use terminal width, & description width 40
+
+       This command also supports the output  destination  and  output  format
+       options  The  output formats supported are txt, csv, and (experimental)
+       json.
+
+   register-match
+       register-match
+       Print the one posting whose transaction description is closest to DESC,
+       in  the  style  of the register command.  If there are multiple equally
+       good matches, it shows the most recent.  Query  options  (options,  not
+       arguments)  can  be  used  to restrict the search space.  Helps ledger-
+       autosync detect already-seen transactions when importing.
+
+   rewrite
+       rewrite
+       Print all transactions, rewriting the postings of matched transactions.
+       For  now  the only rewrite available is adding new postings, like print
+       --auto.
+
+       This is a start at a generic rewriter of transaction entries.  It reads
+       the  default  journal and prints the transactions, like print, but adds
+       one or more specified postings to any transactions matching QUERY.  The
+       posting  amounts can be fixed, or a multiplier of the existing transac-
+       tion's first posting amount.
+
+       Examples:
+
+              $ hledger-rewrite.hs ^income --add-posting '(liabilities:tax)  *.33  ; income tax' --add-posting '(reserve:gifts)  $100'
+              $ hledger-rewrite.hs expenses:gifts --add-posting '(reserve:gifts)  *-1"'
+              $ hledger-rewrite.hs -f rewrites.hledger
+
+       rewrites.hledger may consist of entries like:
+
+              = ^income amt:<0 date:2017
+                (liabilities:tax)  *0.33  ; tax on income
+                (reserve:grocery)  *0.25  ; reserve 25% for grocery
+                (reserve:)  *0.25  ; reserve 25% for grocery
+
+       Note the single quotes to protect the dollar sign from  bash,  and  the
+       two spaces between account and amount.
+
+       More:
+
+              $ hledger rewrite -- [QUERY]        --add-posting "ACCT  AMTEXPR" ...
+              $ hledger rewrite -- ^income        --add-posting '(liabilities:tax)  *.33'
+              $ hledger rewrite -- expenses:gifts --add-posting '(budget:gifts)  *-1"'
+              $ hledger rewrite -- ^income        --add-posting '(budget:foreign currency)  *0.25 JPY; diversify'
+
+       Argument  for  --add-posting  option  is a usual posting of transaction
+       with an exception for amount specification.  More  precisely,  you  can
+       use '*' (star symbol) before the amount to indicate that that this is a
+       factor for an amount  of  original  matched  posting.   If  the  amount
+       includes  a  commodity  name, the new posting amount will be in the new
+       commodity; otherwise, it will be in the matched posting  amount's  com-
+       modity.
+
+   Re-write rules in a file
+       During  the  run  this  tool will execute so called "Automated Transac-
+       tions" found in any journal it process.  I.e instead of specifying this
+       operations in command line you can put them in a journal file.
+
+              $ rewrite-rules.journal
+
+       Make contents look like this:
+
+              = ^income
+                  (liabilities:tax)  *.33
+
+              = expenses:gifts
+                  budget:gifts  *-1
+                  assets:budget  *1
+
+       Note  that '=' (equality symbol) that is used instead of date in trans-
+       actions you usually write.  It indicates the query by which you want to
+       match the posting to add new ones.
+
+              $ hledger rewrite -- -f input.journal -f rewrite-rules.journal > rewritten-tidy-output.journal
+
+       This is something similar to the commands pipeline:
+
+              $ hledger rewrite -- -f input.journal '^income' --add-posting '(liabilities:tax)  *.33' \
+                | hledger rewrite -- -f - expenses:gifts      --add-posting 'budget:gifts  *-1'       \
+                                                              --add-posting 'assets:budget  *1'       \
+                > rewritten-tidy-output.journal
+
+       It  is  important  to understand that relative order of such entries in
+       journal is important.  You can re-use result of previously added  post-
+       ings.
+
+   Diff output format
+       To  use  this tool for batch modification of your journal files you may
+       find useful output in form of unified diff.
+
+              $ hledger rewrite -- --diff -f examples/sample.journal '^income' --add-posting '(liabilities:tax)  *.33'
+
+       Output might look like:

+
+   rewrite vs. print --auto
+       This command predates print --auto, and currently does  much  the  same
+       thing, but with these differences:
+
+       o with  multiple files, rewrite lets rules in any file affect all other
+         files.  print --auto uses standard directive  scoping;  rules  affect
+         only child files.
+
+       o rewrite's  query  limits which transactions can be rewritten; all are
+         printed.  print --auto's query limits which transactions are printed.
+
+       o rewrite  applies  rules  specified on command line or in the journal.
+         print --auto applies rules specified in the journal.
+
+   roi
+       roi
+       Shows the time-weighted (TWR) and money-weighted (IRR) rate  of  return
+       on your investments.
+
+       At  a  minimum,  you  need  to  supply  a query (which could be just an
+       account name) to select your  investment(s)  with  --inv,  and  another
+       query to identify your profit and loss transactions with --pnl.
+
+       If  you do not record changes in the value of your investment manually,
+       or do not require computation  of  time-weighted  return  (TWR),  --pnl
+       could be an empty query (--pnl "" or --pnl STR where STR does not match
+       any of your accounts).
+
+       This command will compute and display the internalized rate  of  return
+       (IRR)  and  time-weighted rate of return (TWR) for your investments for
+       the time period requested.  Both rates of return are annualized  before
+       display, regardless of the length of reporting interval.
+
+       Price  directives  will be taken into account if you supply appropriate
+       --cost or --value flags (see VALUATION).
+
+       Note, in some cases this report can fail, for these reasons:
+
+       o Error (NotBracketed): No solution for Internal Rate of Return  (IRR).
+         Possible  causes:  IRR  is  huge  (>1000000%),  balance of investment
+         becomes negative at some point in time.
+
+       o Error (SearchFailed): Failed to find solution for  Internal  Rate  of
+         Return (IRR).  Either search does not converge to a solution, or con-
+         verges too slowly.
+
+       Examples:
+
+       o Using  roi  to  compute  total  return  of  investment   in   stocks:
+         https://github.com/simonmichael/hledger/blob/master/examples/roi-
+         unrealised.ledger
+
+       o Cookbook -> Return on Investment
+
+   Spaces and special characters in --inv and --pnl
+       Note that --inv and --pnl's argument is a query, and queries could have
+       several space-separated terms (see QUERIES).
+
+       To  indicate  that  all search terms form single command-line argument,
+       you will need to put them in quotes (see Special characters):
+
+              $ hledger roi --inv 'term1 term2 term3 ...'
+
+       If any query terms contain spaces themselves, you will  need  an  extra
+       level of nested quoting, eg:
+
+              $ hledger roi --inv="'Assets:Test 1'" --pnl="'Equity:Unrealized Profit and Loss'"
+
+   Semantics of --inv and --pnl
+       Query  supplied to --inv has to match all transactions that are related
+       to your investment.  Transactions not matching --inv will be ignored.
+
+       In these transactions, ROI will conside postings that match --inv to be
+       "investment  postings"  and other postings (not matching --inv) will be
+       sorted into two categories: "cash flow" and "profit and loss",  as  ROI
+       needs  to know which part of the investment value is your contributions
+       and which is due to the return on investment.
+
+       o "Cash flow" is depositing or withdrawing  money,  buying  or  selling
+         assets, or otherwise converting between your investment commodity and
+         any other commodity.  Example:
+
+                2019-01-01 Investing in Snake Oil
+                  assets:cash          -$100
+                  investment:snake oil
+
+                2020-01-01 Selling my Snake Oil
+                  assets:cash           $10
+                  investment:snake oil  = 0
+
+       o "Profit and loss" is change in the value of your investment:
+
+                2019-06-01 Snake Oil falls in value
+                  investment:snake oil  = $57
+                  equity:unrealized profit or loss
+
+       All non-investment postings are assumed to be "cash flow", unless  they
+       match  --pnl query.  Changes in value of your investment due to "profit
+       and loss" postings will  be  considered  as  part  of  your  investment
+       return.
+
+       Example:  if you use --inv snake --pnl equity:unrealized, then postings
+       in the example below would be classifed as:
+
+              2019-01-01 Snake Oil #1
+                assets:cash          -$100   ; cash flow posting
+                investment:snake oil         ; investment posting
+
+              2019-03-01 Snake Oil #2
+                equity:unrealized pnl  -$100 ; profit and loss posting
+                snake oil                    ; investment posting
+
+              2019-07-01 Snake Oil #3

+
+   IRR and TWR explained
+       "ROI" stands for "return on investment".  Traditionally this  was  com-
+       puted  as a difference between current value of investment and its ini-
+       tial value, expressed in percentage of the initial value.
+
+       However, this approach is only practical in simple cases, where invest-
+       ments  receives  no  in-flows  or out-flows of money, and where rate of
+       growth is fixed over time.  For more complex scenarios you need differ-
+       ent  ways to compute rate of return, and this command implements two of
+       them: IRR and TWR.
+
+       Internal rate of return, or "IRR" (also called "money-weighted rate  of
+       return")   takes  into  account  effects  of  in-flows  and  out-flows.
+       Naively, if you are withdrawing from your investment, your future gains
+       would  be smaller (in absolute numbers), and will be a smaller percent-
+       age of your initial investment, and if you are adding to  your  invest-
+       ment,  you will receive bigger absolute gains (but probably at the same
+       rate of return).  IRR is a way to  compute  rate  of  return  for  each
+       period between in-flow or out-flow of money, and then combine them in a
+       way that gives you a compound annual rate of return that investment  is
+       expected to generate.
+
+       As  mentioned before, in-flows and out-flows would be any cash that you
+       personally put in or withdraw, and for the "roi" command, these are the
+       postings  that  match  the query in the--inv argument and NOT match the
+       query in the--pnl argument.
+
+       If you manually record changes in  the  value  of  your  investment  as
+       transactions  that  balance them against "profit and loss" (or "unreal-
+       ized gains") account or use price directives, then in order for IRR  to
+       compute  the  precise effect of your in-flows and out-flows on the rate
+       of return, you will need to record the value of your investement on  or
+       close to the days when in- or out-flows occur.
+
+       In  technical  terms,  IRR uses the same approach as computation of net
+       present value, and tries to find a discount rate that makes net present
+       value of all the cash flows of your investment to add up to zero.  This
+       could be hard to wrap your head around, especially if you haven't  done
+       discounted cash flow analysis before.  Implementation of IRR in hledger
+       should produce results that match the XIRR formula in Excel.
+
+       Second way to compute rate of return that  roi  command  implements  is
+       called "time-weighted rate of return" or "TWR".  Like IRR, it will also
+       break the history of your investment  into  periods  between  in-flows,
+       out-flows  and value changes, to compute rate of return per each period
+       and then a compound rate of return.  However, internal workings of  TWR
+       are quite different.
+
+       TWR  represents  your  investment as an imaginary "unit fund" where in-
+       flows/ out-flows lead to buying or selling "units" of  your  investment
+       and changes in its value change the value of "investment unit".  Change
+       in "unit price" over the reporting period gives you rate of  return  of
+       your investment.

+
+   stats
+       stats
+       Show some journal statistics.
+
+       The  stats  command displays summary information for the whole journal,
+       or a matched part of it.  With a reporting interval, it shows a  report
+       for each report period.
+
+       Example:
+
+              $ hledger stats
+              Main journal file        : /src/hledger/examples/sample.journal
+              Included journal files   :
+              Transactions span        : 2008-01-01 to 2009-01-01 (366 days)
+              Last transaction         : 2008-12-31 (2333 days ago)
+              Transactions             : 5 (0.0 per day)
+              Transactions last 30 days: 0 (0.0 per day)
+              Transactions last 7 days : 0 (0.0 per day)
+              Payees/descriptions      : 5
+              Accounts                 : 8 (depth 3)
+              Commodities              : 1 ($)
+              Market prices            : 12 ($)
+
+       This  command also supports output destination and output format selec-
+       tion.
+
+   tags
+       tags
+       List the unique tag names used in the journal.  With a  TAGREGEX  argu-
+       ment, only tag names matching the regular expression (case insensitive)
+       are shown.  With QUERY arguments, only transactions matching the  query
+       are considered.
+
+       With the --values flag, the tags' unique values are listed instead.
+
+       With  --parsed flag, all tags or values are shown in the order they are
+       parsed from the input data, including duplicates.
+
+       With -E/--empty, any blank/empty values will also be  shown,  otherwise
+       they are omitted.
+
+   test
+       test
+       Run built-in unit tests.
+
+       This  command  runs the unit tests built in to hledger and hledger-lib,
+       printing the results on stdout.  If any test fails, the exit code  will
+       be non-zero.
+
+       This  is  mainly used by hledger developers, but you can also use it to
+       sanity-check the installed hledger executable on  your  platform.   All
+       tests  are  expected to pass - if you ever see a failure, please report
+       as a bug!
+
+       This command also accepts tasty test runner options, written after a --
+       (double hyphen).  Eg to run only the tests in Hledger.Data.Amount, with
+       ANSI colour codes disabled:
+
+              $ hledger test -- -pData.Amount --color=never
+
+       For help on these, see  https://github.com/feuerbach/tasty#options  (--
+       --help currently doesn't show them).
+
+   About add-on commands
+       Add-on commands are programs or scripts in your PATH
+
+       o whose name starts with hledger-
+
+       o whose  name  ends  with  a recognised file extension: .bat,.com,.exe,
+         .hs,.lhs,.pl,.py,.rb,.rkt,.sh or none
+
+       o and (on unix, mac) which are executable by the current user.
+
+       Add-ons are a relatively easy way to add local features  or  experiment
+       with  new  ideas.   They  can  be  written in any language, but haskell
+       scripts have a big advantage: they can use  the  same  hledger  library
+       functions  that built-in commands use for command-line options, parsing
+       and reporting.  Some experimental/example add-on scripts can  be  found
+       in the hledger repo's bin/ directory.
+
+       Note in a hledger command line, add-on command flags must have a double
+       dash (--) preceding them.  Eg you must write:
+
+              $ hledger web -- --serve
+
+       and not:
+
+              $ hledger web --serve
+
+       (because the --serve flag belongs to hledger-web, not hledger).
+
+       The -h/--help and --version flags don't require --.
+
+       If you have any trouble with this, remember you can always run the add-
+       on program directly, eg:
+
+              $ hledger-web --serve
+
+JOURNAL FORMAT
+       hledger's default file format, representing a General Journal.
+
+       hledger's  usual  data  source  is a plain text file containing journal
+       entries in hledger journal format.  This  file  represents  a  standard
+       accounting  general  journal.  I use file names ending in .journal, but
+       that's not required.  The journal file contains a number of transaction
+       entries, each describing a transfer of money (or any commodity) between
+       two or more named accounts, in a simple format readable by both hledger
+       and humans.
+
+       hledger's  journal  format  is a compatible subset, mostly, of ledger's
+       journal format, so hledger can  work  with  compatible  ledger  journal
+       files  as  well.   It's  safe,  and encouraged, to run both hledger and
+       ledger on the same journal file, eg to validate the results you're get-
+       ting.
+
+       You can use hledger without learning any more about this file; just use
+       the add or web or import commands to create and update it.
+
+       Many users, though, edit the journal file with a text editor, and track
+       changes  with a version control system such as git.  Editor addons such
+       as ledger-mode or hledger-mode  for  Emacs,  vim-ledger  for  Vim,  and
+       hledger-vscode for Visual Studio Code, make this easier, adding colour,
+       formatting, tab completion, and useful commands.  See Editor configura-
+       tion at hledger.org for the full list.
+
+       Here's  a  description  of  each part of the file format (and hledger's
+       data model).  These are mostly in the order you'll  use  them,  but  in
+       some  cases related concepts have been grouped together for easy refer-
+       ence, or linked before they are introduced, so feel free to  skip  over
+       anything that looks unnecessary right now.
+
+   Transactions
+       Transactions  are the main unit of information in a journal file.  They
+       represent events, typically a movement of some quantity of  commodities
+       between two or more named accounts.
+
+       Each  transaction is recorded as a journal entry, beginning with a sim-
+       ple date in column 0.  This can be followed by  any  of  the  following
+       optional fields, separated by spaces:
+
+       o a status character (empty, !, or *)
+
+       o a code (any short number or text, enclosed in parentheses)
+
+       o a description (any remaining text until end of line or a semicolon)
+
+       o a  comment  (any  remaining  text  following a semicolon until end of
+         line, and any following indented lines beginning with a semicolon)
+
+       o 0 or more indented posting lines, describing what was transferred and
+         the  accounts  involved (indented comment lines are also allowed, but
+         not blank lines or non-indented lines).
+
+       Here's a simple journal file containing one transaction:
+
+              2008/01/01 income
+                assets:bank:checking   $1
+                income:salary         $-1
+
+   Dates
+   Simple dates
+       Dates in the journal  file  use  simple  dates  format:  YYYY-MM-DD  or
+       YYYY/MM/DD or YYYY.MM.DD, with leading zeros optional.  The year may be
+       omitted, in which case it will be inferred from the context:  the  cur-
+       rent  transaction,  the default year set with a default year directive,
+       or  the  current  date  when  the  command  is  run.   Some   examples:
+       2010-01-31, 2010/01/31, 2010.1.31, 1/31.
+
+       (The  UI  also accepts simple dates, as well as the more flexible smart
+       dates documented in the hledger manual.)
+
+   Secondary dates
+       Real-life transactions sometimes involve more than one date  -  eg  the
+       date you write a cheque, and the date it clears in your bank.  When you
+       want to model this, for more accurate daily balances, you  can  specify
+       individual posting dates.
+
+       Or,  you can use the older secondary date feature (Ledger calls it aux-
+       iliary date or effective date).  Note: we support this for  compatibil-
+       ity,  but  I usually recommend avoiding this feature; posting dates are
+       almost always clearer and simpler.
+
+       A secondary date is written after the primary date, following an equals
+       sign.   If  the  year  is  omitted, the primary date's year is assumed.
+       When running reports, the primary (left) date is used by  default,  but
+       with  the  --date2  flag  (or --aux-date or --effective), the secondary
+       (right) date will be used instead.
+
+       The meaning of secondary dates is up to you, but it's best to follow  a
+       consistent  rule.   Eg "primary = the bank's clearing date, secondary =
+       date the transaction was initiated, if different", as shown here:
+
+              2010/2/23=2/19 movie ticket
+                expenses:cinema                   $10
+                assets:checking
+
+              $ hledger register checking
+              2010-02-23 movie ticket         assets:checking                $-10         $-10
+
+              $ hledger register checking --date2
+              2010-02-19 movie ticket         assets:checking                $-10         $-10
+
+   Posting dates
+       You can give individual postings a different  date  from  their  parent
+       transaction,  by  adding a posting comment containing a tag (see below)
+       like date:DATE.  This is probably the best way to control posting dates
+       precisely.   Eg  in  this  example  the  expense  should  appear in May
+       reports, and the deduction from checking should be reported on 6/1  for
+       easy bank reconciliation:
+
+              2015/5/30
+                  expenses:food     $10  ; food purchased on saturday 5/30
+                  assets:checking        ; bank cleared it on monday, date:6/1
+
+              $ hledger -f t.j register food
+              2015-05-30                      expenses:food                  $10           $10
+
+              $ hledger -f t.j register checking
+              2015-06-01                      assets:checking               $-10          $-10
+
+       DATE  should be a simple date; if the year is not specified it will use
+       the year of the transaction's date.  You can  set  the  secondary  date
+       similarly,  with  date2:DATE2.   The  date:  or date2: tags must have a
+       valid simple date value if they are present, eg a  date:  tag  with  no
+       value is not allowed.
+
+       Ledger's earlier, more compact bracketed date syntax is also supported:
+       [DATE], [DATE=DATE2] or [=DATE2].  hledger will attempt  to  parse  any
+       square-bracketed sequence of the 0123456789/-.= characters in this way.
+       With this syntax, DATE infers its year from the transaction  and  DATE2
+       infers its year from DATE.
+
+   Status
+       Transactions,  or  individual postings within a transaction, can have a
+       status mark,  which  is  a  single  character  before  the  transaction
+       description  or  posting  account  name,  separated from it by a space,
+       indicating one of three statuses:
+
+
+       mark     status
+       ------------------
+                unmarked
+       !        pending
+       *        cleared
+
+       When reporting, you  can  filter  by  status  with  the  -U/--unmarked,
+       -P/--pending,  and  -C/--cleared  flags;  or the status:, status:!, and
+       status:* queries; or the U, P, C keys in hledger-ui.
+
+       Note, in Ledger and in older versions of hledger, the "unmarked"  state
+       is  called  "uncleared".   As  of  hledger  1.3  we  have renamed it to
+       unmarked for clarity.
+
+       To replicate Ledger and old hledger's behaviour of also matching  pend-
+       ing, combine -U and -P.
+
+       Status  marks  are optional, but can be helpful eg for reconciling with
+       real-world accounts.  Some editor modes provide highlighting and short-
+       cuts  for working with status.  Eg in Emacs ledger-mode, you can toggle
+       transaction status with C-c C-e, or posting status with C-c C-c.
+
+       What "uncleared", "pending", and "cleared" actually mean is up to  you.
+       Here's one suggestion:
+
+
+       status       meaning
+       --------------------------------------------------------------------------
+       uncleared    recorded but not yet reconciled; needs review
+       pending      tentatively reconciled (if needed, eg during a big reconcil-
+                    iation)
+       cleared      complete, reconciled as far as possible, and considered cor-
+                    rect
+
+       With  this scheme, you would use -PC to see the current balance at your
+       bank, -U to see things which will probably hit  your  bank  soon  (like
+       uncashed checks), and no flags to see the most up-to-date state of your
+       finances.
+
+   Code
+       After the status mark, but before the description, you  can  optionally
+       write  a  transaction  "code", enclosed in parentheses.  This is a good
+       place to record a check number, or some other important transaction  id
+       or reference number.
+
+   Description
+       A  transaction's description is the rest of the line following the date
+       and status mark (or until a  comment  begins).   Sometimes  called  the
+       "narration" in traditional bookkeeping, it can be used for whatever you
+       wish, or left blank.  Transaction descriptions can be  queried,  unlike
+       comments.
+
+   Payee and note
+       You can optionally include a | (pipe) character in descriptions to sub-
+       divide the description into separate fields for payee/payer name on the
+       left  (up  to  the  first  |) and an additional note field on the right
+       (after the first |).  This may be worthwhile if you  need  to  do  more
+       precise querying and pivoting by payee or by note.
+
+   Comments
+       Lines in the journal beginning with a semicolon (;) or hash (#) or star
+       (*) are comments, and will be ignored.  (Star comments  cause  org-mode
+       nodes  to  be  ignored, allowing emacs users to fold and navigate their
+       journals with org-mode or orgstruct-mode.)
+
+       You can attach comments to a transaction  by  writing  them  after  the
+       description  and/or  indented  on the following lines (before the post-
+       ings).  Similarly, you can attach comments to an individual posting  by
+       writing  them  after the amount and/or indented on the following lines.
+       Transaction and posting comments must begin with a semicolon (;).
+
+       Some examples:
+
+              # a file comment
+              ; another file comment
+              * also a file comment, useful in org/orgstruct mode
+
+              comment
+              A multiline file comment, which continues
+              until a line containing just "end comment"
+              (or end of file).
+              end comment
+
+              2012/5/14 something  ; a transaction comment
+                  ; the transaction comment, continued
+                  posting1  1  ; a comment for posting 1
+                  posting2
+                  ; a comment for posting 2
+                  ; another comment line for posting 2
+              ; a file comment (because not indented)
+
+       You can also comment larger regions of a file  using  comment  and  end
+       comment directives.
+
+   Tags
+       Tags  are  a  way  to add extra labels or labelled data to postings and
+       transactions, which you can then search or pivot on.
+
+       A simple tag is a word (which may contain hyphens) followed by  a  full
+       colon, written inside a transaction or posting comment line:
+
+              2017/1/16 bought groceries  ; sometag:
+
+       Tags  can  have  a  value, which is the text after the colon, up to the
+       next comma or end of line, with leading/trailing whitespace removed:
+
+                  expenses:food    $10 ; a-posting-tag: the tag value
+
+       Note this means hledger's tag values can not  contain  commas  or  new-
+       lines.  Ending at commas means you can write multiple short tags on one
+       line, comma separated:
+
+                  assets:checking  ; a comment containing tag1:, tag2: some value ...
+
+       Here,
+
+       o "a comment containing" is just comment text, not a tag
+
+       o "tag1" is a tag with no value
+
+       o "tag2" is another tag, whose value is "some value ..."
+
+       Tags in a transaction comment affect the transaction  and  all  of  its
+       postings,  while  tags  in  a posting comment affect only that posting.
+       For example, the following transaction has three tags (A, TAG2,  third-
+       tag) and the posting has four (those plus posting-tag):
+
+              1/1 a transaction  ; A:, TAG2:
+                  ; third-tag: a third transaction tag, <- with a value
+                  (a)  $1  ; posting-tag:
+
+       Tags  are  like  Ledger's metadata feature, except hledger's tag values
+       are simple strings.
+
+   Postings
+       A posting is an addition of some amount to, or removal of  some  amount
+       from,  an account.  Each posting line begins with at least one space or
+       tab (2 or 4 spaces is common), followed by:
+
+       o (optional) a status character (empty, !, or *), followed by a space
+
+       o (required) an account name (any text,  optionally  containing  single
+         spaces, until end of line or a double space)
+
+       o (optional) two or more spaces or tabs followed by an amount.
+
+       Positive  amounts  are being added to the account, negative amounts are
+       being removed.
+
+       The amounts within a transaction must always sum up to zero.  As a con-
+       venience,  one  amount  may be left blank; it will be inferred so as to
+       balance the transaction.
+
+       Be sure to note the unusual two-space delimiter  between  account  name
+       and  amount.  This makes it easy to write account names containing spa-
+       ces.  But if you accidentally leave only one space (or tab) before  the
+       amount, the amount will be considered part of the account name.
+
+   Virtual postings
+       A posting with a parenthesised account name is called a virtual posting
+       or unbalanced posting, which means it is exempt  from  the  usual  rule
+       that a transaction's postings must balance add up to zero.
+
+       This  is  not  part  of double entry accounting, so you might choose to
+       avoid this feature.  Or you can use it sparingly  for  certain  special
+       cases  where  it can be convenient.  Eg, you could set opening balances
+       without using a balancing equity account:
+
+              1/1 opening balances
+                (assets:checking)   $1000
+                (assets:savings)    $2000
+
+       A posting with a bracketed account name is called  a  balanced  virtual
+       posting.  The balanced virtual postings in a transaction must add up to
+       zero (separately from other postings).  Eg:
+
+              1/1 buy food with cash, update budget envelope subaccounts, & something else
+                assets:cash                    $-10 ; <- these balance
+                expenses:food                    $7 ; <-
+                expenses:food                    $3 ; <-
+                [assets:checking:budget:food]  $-10    ; <- and these balance
+                [assets:checking:available]     $10    ; <-
+                (something:else)                 $5       ; <- not required to balance
+
+       Ordinary non-parenthesised,  non-bracketed  postings  are  called  real
+       postings.   You  can  exclude  virtual  postings  from reports with the
+       -R/--real flag or real:1 query.
+
+   Account names
+       Account names typically have several parts separated by a  full  colon,
+       from  which hledger derives a hierarchical chart of accounts.  They can
+       be anything you like, but in finance there are traditionally five  top-
+       level accounts: assets, liabilities, revenue, expenses, and equity.
+
+       Account  names  may  contain single spaces, eg: assets:accounts receiv-
+       able.  Because of this, they must always be followed  by  two  or  more
+       spaces (or newline).
+
+       Account names can be aliased.
+
+   Amounts
+       After  the  account  name,  there  is  usually  an amount.  (Important:
+       between account name and amount, there must be two or more spaces.)
+
+       hledger's amount format is flexible, supporting  several  international
+       formats.   Here  are  some examples.  Amounts have a number (the "quan-
+       tity"):
+
+              1
+
+       ..and usually a currency symbol or commodity name (more on this below),
+       to  the  left  or  right  of the quantity, with or without a separating
+       space:
+
+              $1
+              4000 AAPL
+              3 "green apples"
+
+       Amounts can be preceded by a minus sign (or a plus sign, though plus is
+       the  default), The sign can be written before or after a left-side com-
+       modity symbol:
+
+              -$1
+              $-1
+
+       One or more spaces between the sign and the number are acceptable  when
+       parsing (but they won't be displayed in output):
+
+              + $1
+              $-      1
+
+       Scientific E notation is allowed:
+
+              1E-6
+              EUR 1E3
+
+   Decimal marks, digit group marks
+       A decimal mark can be written as a period or a comma:
+
+              1.23
+              1,23456780000009
+
+       In  the integer part of the quantity (left of the decimal mark), groups
+       of digits can optionally be separated by  a  "digit  group  mark"  -  a
+       space, comma, or period (different from the decimal mark):
+
+                   $1,000,000.00
+                EUR 2.000.000,00
+              INR 9,99,99,999.00
+                    1 000 000.9455
+
+       Note, a number containing a single digit group mark and no decimal mark
+       is ambiguous.  Are these digit group marks or decimal marks ?
+
+              1,000
+              1.000
+
+       If you don't tell it otherwise, hledger will assume both of  the  above
+       are decimal marks, parsing both numbers as 1.  To prevent confusion and
+       undetected typos, we recommend adding commodity directives at  the  top
+       of  your  journal  file  to  explicitly  declare  the decimal mark (and
+       optionally a digit group mark) for each commodity.  Read  on  for  more
+       about this.
+
+   Commodity
+       Amounts  in  hledger  have both a "quantity", which is a signed decimal
+       number, and a "commodity", which is a currency symbol, stock ticker, or
+       any word or phrase describing something you are tracking.
+
+       If the commodity name contains non-letters (spaces, numbers, or punctu-
+       ation), you must always write it inside double quotes ("green  apples",
+       "ABC123").
+
+       If  you  write just a bare number, that too will have a commodity, with
+       name ""; we call that the "no-symbol commodity".
+
+       Actually, hledger combines these  single-commodity  amounts  into  more
+       powerful  multi-commodity amounts, which are what it works with most of
+       the time.  A multi-commodity amount could be, eg: 1 USD, 2  EUR,  3.456
+       TSLA.   In  practice,  you  will  only  see  multi-commodity amounts in
+       hledger's output; you can't write them directly in the journal file.
+
+       (If you are writing scripts or working with hledger's internals,  these
+       are the Amount and MixedAmount types.)
+
+   Commodity directives
+       You can add commodity directives to the journal, preferably at the top,
+       to declare your commodities and help with number  parsing  (see  above)
+       and  display  (see  below).  These are optional, but recommended.  They
+       are described in more detail in JOURNAL FORMAT  ->  Declaring  commodi-
+       ties.  Here's a quick example:
+
+              # number format and display style for $, EUR, INR and the no-symbol commodity:
+              commodity $1,000.00
+              commodity EUR 1.000,00
+              commodity INR 9,99,99,999.00
+              commodity 1 000 000.9455
+
+
+   Commodity display style
+       For the amounts in each commodity, hledger chooses a consistent display
+       style to use in most reports.   (Exceptions:  price  amounts,  and  all
+       amounts displayed by the print command, are displayed with all of their
+       decimal digits visible.)
+
+       A commodity's display style is inferred as follows.
+
+       First, if a default commodity is declared with D,  this  commodity  and
+       its style is applied to any no-symbol amounts in the journal.
+
+       Then  each  commodity's style is inferred from one of the following, in
+       order of preference:
+
+       o The commodity directive for that commodity (including  the  no-symbol
+         commodity), if any.
+
+       o The  amounts  in  that  commodity seen in the journal's transactions.
+         (Posting amounts only; prices and periodic or auto rules are ignored,
+         currently.)
+
+       o The  built-in fallback style, which looks like this: $1000.00.  (Sym-
+         bol on the left, period decimal mark, two decimal places.)
+
+       A style is inferred from journal amounts as follows:
+
+       o Use the general style (decimal mark, symbol placement) of  the  first
+         amount
+
+       o Use  the  first-seen digit group style (digit group mark, digit group
+         sizes), if any
+
+       o Use the maximum number of decimal places of all.
+
+       Transaction price amounts don't  affect  the  commodity  display  style
+       directly,  but  occasionally they can do so indirectly (eg when a post-
+       ing's amount is inferred using a transaction price).  If you find  this
+       causing problems, use a commodity directive to fix the display style.
+
+       To  summarise:  each  commodity's amounts will be normalised to (a) the
+       style declared by a commodity directive, or (b) the style of the  first
+       posting  amount  in  the journal, with the first-seen digit group style
+       and the maximum-seen number of decimal places.  So if your reports  are
+       showing  amounts  in  a  way  you  don't like, eg with too many decimal
+       places, use a commodity directive.  Some examples:
+
+              # declare euro, dollar, bitcoin and no-symbol commodities and set their
+              # input number formats and output display styles:
+              commodity EUR 1.000,
+              commodity $1000.00
+              commodity 1000.00000000 BTC
+              commodity 1 000.
+
+   Rounding
+       Amounts are stored internally as decimal numbers with up to 255 decimal
+       places,  and  displayed  with the number of decimal places specified by
+       the commodity display style.  Note, hledger uses banker's rounding:  it
+       rounds  to  the nearest even number, eg 0.5 displayed with zero decimal
+       places is "0").  (Guaranteed since hledger 1.17.1;  in  older  versions
+       this could vary if hledger was built with Decimal < 0.5.1.)
+
+   Transaction prices
+       Within a transaction, you can note an amount's price in another commod-
+       ity.  This can be used to document the cost (in a purchase) or  selling
+       price  (in  a  sale).   For  example,  transaction prices are useful to
+       record purchases of a foreign currency.  Note  transaction  prices  are
+       fixed at the time of the transaction, and do not change over time.  See
+       also market prices, which represent prevailing exchange rates on a cer-
+       tain date.
+
+       There are several ways to record a transaction price:
+
+       1. Write the price per unit, as @ UNITPRICE after the amount:
+
+                  2009/1/1
+                    assets:euros     EUR100 @ $1.35  ; one hundred euros purchased at $1.35 each
+                    assets:dollars                 ; balancing amount is -$135.00
+
+       2. Write the total price, as @@ TOTALPRICE after the amount:
+
+                  2009/1/1
+                    assets:euros     EUR100 @@ $135  ; one hundred euros purchased at $135 for the lot
+                    assets:dollars
+
+       3. Specify amounts for all postings, using exactly two commodities, and
+          let hledger infer the price that balances the transaction:
+
+                  2009/1/1
+                    assets:euros     EUR100          ; one hundred euros purchased
+                    assets:dollars  $-135          ; for $135
+
+       4. Like 1, but the @ is parenthesised, i.e.  (@); this is for  compati-
+          bility  with Ledger journals (Virtual posting costs), and is equiva-
+          lent to 1 in hledger.
+
+       5. Like 2, but as in 4 the @@ is parenthesised, i.e.  (@@); in hledger,
+          this is equivalent to 2.
+
+       Use  the -B/--cost flag to convert amounts to their transaction price's
+       commodity, if any.  (mnemonic: "B" is from "cost Basis", as in Ledger).
+       Eg here is how -B affects the balance report for the example above:
+
+              $ hledger bal -N --flat
+                             $-135  assets:dollars
+                              EUR100  assets:euros
+              $ hledger bal -N --flat -B
+                             $-135  assets:dollars
+                              $135  assets:euros    # <- the euros' cost
+
+       Note  -B is sensitive to the order of postings when a transaction price
+       is inferred: the inferred price will be in the commodity  of  the  last
+       amount.  So if example 3's postings are reversed, while the transaction
+       is equivalent, -B shows something different:
+
+              2009/1/1
+                assets:dollars  $-135              ; 135 dollars sold
+                assets:euros     EUR100              ; for 100 euros
+
+              $ hledger bal -N --flat -B
+                             EUR-100  assets:dollars  # <- the dollars' selling price
+                              EUR100  assets:euros
+
+   Lot prices, lot dates
+       Ledger allows another kind of price, lot price (four  variants:  {UNIT-
+       PRICE},   {{TOTALPRICE}},   {=FIXEDUNITPRICE},   {{=FIXEDTOTALPRICE}}),
+       and/or a lot date ([DATE]) to be specified.  These are normally used to
+       select  a  lot when selling investments.  hledger will parse these, for
+       compatibility with Ledger journals,  but  currently  ignores  them.   A
+       transaction  price,  lot price and/or lot date may appear in any order,
+       after the posting amount and before the balance assertion if any.
+
+   Balance assertions
+       hledger supports Ledger-style  balance  assertions  in  journal  files.
+       These  look  like, for example, = EXPECTEDBALANCE following a posting's
+       amount.  Eg here we assert the expected dollar balance  in  accounts  a
+       and b after each posting:
+
+              2013/1/1
+                a   $1  =$1
+                b       =$-1
+
+              2013/1/2
+                a   $1  =$2
+                b  $-1  =$-2
+
+       After reading a journal file, hledger will check all balance assertions
+       and report an error if any of them fail.  Balance assertions  can  pro-
+       tect  you  from, eg, inadvertently disrupting reconciled balances while
+       cleaning up old entries.  You can disable  them  temporarily  with  the
+       -I/--ignore-assertions flag, which can be useful for troubleshooting or
+       for reading Ledger files.  (Note: this flag currently does not  disable
+       balance assignments, below).
+
+   Assertions and ordering
+       hledger  sorts  an  account's postings and assertions first by date and
+       then (for postings on the same day) by parse order.  Note this is  dif-
+       ferent from Ledger, which sorts assertions only by parse order.  (Also,
+       Ledger assertions do not see the accumulated effect of  repeated  post-
+       ings to the same account within a transaction.)
+
+       So, hledger balance assertions keep working if you reorder differently-
+       dated transactions within the journal.  But if you  reorder  same-dated
+       transactions  or postings, assertions might break and require updating.
+       This order dependence does bring an advantage: precise control over the
+       order of postings and assertions within a day, so you can assert intra-
+       day balances.
+
+   Assertions and included files
+       With included files, things are a little more  complicated.   Including
+       preserves  the ordering of postings and assertions.  If you have multi-
+       ple postings to an account on the  same  day,  split  across  different
+       files,  and  you  also want to assert the account's balance on the same
+       day, you'll have to put the assertion in the right file.
+
+   Assertions and multiple -f options
+       Balance assertions don't work well across files specified with multiple
+       -f options.  Use include or concatenate the files instead.
+
+   Assertions and commodities
+       The  asserted  balance must be a simple single-commodity amount, and in
+       fact the assertion checks only  this  commodity's  balance  within  the
+       (possibly  multi-commodity)  account  balance.   This is how assertions
+       work in Ledger also.  We could call this a "partial" balance assertion.
+
+       To assert the balance of more than one commodity in an account, you can
+       write multiple postings, each asserting one commodity's balance.
+
+       You can make a stronger "total" balance assertion by writing  a  double
+       equals sign (== EXPECTEDBALANCE).  This asserts that there are no other
+       unasserted commodities in the account (or, that their balance is 0).
+
+              2013/1/1
+                a   $1
+                a    1EUR
+                b  $-1
+                c   -1EUR
+
+              2013/1/2  ; These assertions succeed
+                a    0  =  $1
+                a    0  =   1EUR
+                b    0 == $-1
+                c    0 ==  -1EUR
+
+              2013/1/3  ; This assertion fails as 'a' also contains 1EUR
+                a    0 ==  $1
+
+       It's not yet possible to make a complete assertion about a balance that
+       has  multiple commodities.  One workaround is to isolate each commodity
+       into its own subaccount:
+
+              2013/1/1
+                a:usd   $1
+                a:euro   1EUR
+                b
+
+              2013/1/2
+                a        0 ==  0
+                a:usd    0 == $1
+                a:euro   0 ==  1EUR
+
+   Assertions and prices
+       Balance assertions ignore transaction prices, and  should  normally  be
+       written without one:
+
+              2019/1/1
+                (a)     $1 @ EUR1 = $1
+
+       We  do allow prices to be written there, however, and print shows them,
+       even though they don't affect whether the assertion  passes  or  fails.
+       This  is  for  backward  compatibility (hledger's close command used to
+       generate balance assertions with prices), and because  balance  assign-
+       ments do use them (see below).
+
+   Assertions and subaccounts
+       The  balance  assertions above (= and ==) do not count the balance from
+       subaccounts; they check the account's exclusive balance only.  You  can
+       assert the balance including subaccounts by writing =* or ==*, eg:
+
+              2019/1/1
+                equity:opening balances
+                checking:a       5
+                checking:b       5
+                checking         1  ==* 11
+
+   Assertions and virtual postings
+       Balance assertions are checked against all postings, both real and vir-
+       tual.  They are not affected by the --real/-R flag or real: query.
+
+   Assertions and precision
+       Balance assertions compare the exactly calculated  amounts,  which  are
+       not  always  what  is  shown  by reports.  Eg a commodity directive may
+       limit the display precision, but this will not  affect  balance  asser-
+       tions.  Balance assertion failure messages show exact amounts.
+
+   Balance assignments
+       Ledger-style  balance  assignments  are also supported.  These are like
+       balance assertions, but with no posting amount on the left side of  the
+       equals  sign;  instead  it is calculated automatically so as to satisfy
+       the assertion.  This can be a convenience during data  entry,  eg  when
+       setting opening balances:
+
+              ; starting a new journal, set asset account balances
+              2016/1/1 opening balances
+                assets:checking            = $409.32
+                assets:savings             = $735.24
+                assets:cash                 = $42
+                equity:opening balances
+
+       or when adjusting a balance to reality:
+
+              ; no cash left; update balance, record any untracked spending as a generic expense
+              2016/1/15
+                assets:cash    = $0
+                expenses:misc
+
+       The calculated amount depends on the account's balance in the commodity
+       at that point (which depends on the previously-dated  postings  of  the
+       commodity  to  that account since the last balance assertion or assign-
+       ment).  Note that using balance assignments makes your journal a little
+       less explicit; to know the exact amount posted, you have to run hledger
+       or do the calculations yourself, instead of just reading it.
+
+   Balance assignments and prices
+       A transaction price in a balance assignment will cause  the  calculated
+       amount to have that price attached:
+
+              2019/1/1
+                (a)             = $1 @ EUR2
+
+              $ hledger print --explicit
+              2019-01-01
+                  (a)         $1 @ EUR2 = $1 @ EUR2
+
+   Directives
+       A  directive is a line in the journal beginning with a special keyword,
+       that influences how the journal is processed.  hledger's directives are
+       based on a subset of Ledger's, but there are many differences (and also
+       some differences between hledger versions).
+
+       Directives' behaviour and interactions can get a little bit complex, so
+       here  is  a  table  summarising  the directives and their effects, with
+       links to more detailed docs.

+       tive     are affected by a directive
+       scope
+
+       As you can see, directives vary in which journal entries and files they
+       affect, and whether they are focussed  on  input  (parsing)  or  output
+       (reports).  Some directives have multiple effects.
+
+   Directives and multiple files
+       If  you  use  multiple  -f/--file  options,  or  the include directive,
+       hledger will process multiple input files.  But  note  that  directives
+       which affect input (see above) typically last only until the end of the
+       file in which they occur.
+
+       This may seem inconvenient, but it's intentional; it makes reports sta-
+       ble  and  deterministic,  independent of the order of input.  Otherwise
+       you could see different numbers if you happened to write -f options  in
+       a  different  order,  or if you moved includes around while cleaning up
+       your files.
+
+       It can be surprising though; for example, it means  that  alias  direc-
+       tives do not affect parent or sibling files (see below).
+
+   Comment blocks
+       A  line  containing just comment starts a commented region of the file,
+       and a line containing just end comment (or the end of the current file)
+       ends it.  See also comments.
+
+   Including other files
+       You  can  pull in the content of additional files by writing an include
+       directive, like this:
+
+              include FILEPATH
+
+       Only journal files can include, and only journal, timeclock or  timedot
+       files can be included (not CSV files, currently).
+
+       If  the  file  path  does not begin with a slash, it is relative to the
+       current file's folder.
+
+       A tilde means home directory, eg: include ~/main.journal.
+
+       The path may contain glob patterns to match multiple files, eg: include
+       *.journal.
+
+       There  is  limited  support  for recursive wildcards: **/ (the slash is
+       required) matches 0 or more subdirectories.  It's not super  convenient
+       since  you  have to avoid include cycles and including directories, but
+       this can be done, eg: include */**/*.journal.
+
+       The path may also be prefixed to force a specific file format, overrid-
+       ing  the  file  extension  (as  described in hledger.1 -> Input files):
+       include timedot:~/notes/2020*.md.
+
+   Default year
+       You can set a default year to be used for subsequent dates which  don't
+       specify  a year.  This is a line beginning with Y followed by the year.
+       Eg:
+
+              Y2009  ; set default year to 2009
+
+              12/15  ; equivalent to 2009/12/15
+                expenses  1
+                assets
+
+              Y2010  ; change default year to 2010
+
+              2009/1/30  ; specifies the year, not affected
+                expenses  1
+                assets
+
+              1/31   ; equivalent to 2010/1/31
+                expenses  1
+                assets
+
+   Declaring payees
+       The payee directive can be used to declare  a  limited  set  of  payees
+       which  may appear in transaction descriptions.  The "payees" check will
+       report an error if any transaction refers to a payee that has not  been
+       declared.  Eg:
+
+              payee Whole Foods
+
+   Declaring commodities
+       You  can use commodity directives to declare your commodities.  In fact
+       the commodity directive performs several functions at once:
+
+       1. It declares commodities which may be used in the journal.  This  can
+          optionally  be  enforced, providing useful error checking.  (Cf Com-
+          modity error checking)
+
+       2. It declares which decimal  mark  character  (period  or  comma),  to
+          expect  when  parsing  input  - useful to disambiguate international
+          number formats in your data.  Without this, hledger will parse  both
+          1,000 and 1.000 as 1.  (Cf Amounts)
+
+       3. It  declares  how  to render the commodity's amounts when displaying
+          output - the decimal mark, any digit group marks, the number of dec-
+          imal  places,  symbol  placement  and  so on.  (Cf Commodity display
+          style)
+
+       You will run into one of the problems solved  by  commodity  directives
+       sooner or later, so we recommend using them, for robust and predictable
+       parsing and display.
+
+       Generally you should put them at the top of your  journal  file  (since
+       for function 2, they affect only following amounts, cf #793).
+
+       A  commodity  directive is just the word commodity followed by a sample
+       amount, like this:
+
+              ;commodity SAMPLEAMOUNT
+
+              commodity $1000.00
+              commodity 1,000.0000 AAAA  ; optional same-line comment
+
+       It may also be written on multiple lines, and use the format  subdirec-
+       tive,  as  in  Ledger.   Note in this case the commodity symbol appears
+       twice; it must be the same in both places:
+
+              ;commodity SYMBOL
+              ;  format SAMPLEAMOUNT
+
+              ; display indian rupees with currency name on the left,
+              ; thousands, lakhs and crores comma-separated,
+              ; period as decimal point, and two decimal places.
+              commodity INR
+                format INR 1,00,00,000.00
+
+       Remember that if the commodity  symbol  contains  spaces,  numbers,  or
+       punctuation, it must be enclosed in double quotes (cf Commodity).
+
+       The  amount's quantity does not matter; only the format is significant.
+       It must include a decimal mark - either a period or a comma -  followed
+       by 0 or more decimal digits.
+
+       A few more examples:
+
+              # number formats for $, EUR, INR and the no-symbol commodity:
+              commodity $1,000.00
+              commodity EUR 1.000,00
+              commodity INR 9,99,99,999.0
+              commodity 1 000 000.
+
+       Note  hledger  normally  uses  banker's rounding, so 0.5 displayed with
+       zero decimal digits is "0".  (More at Commodity display style.)
+
+   Commodity error checking
+       In strict mode, enabled with the -s/--strict flag, hledger will  report
+       an  error if a commodity symbol is used that has not been declared by a
+       commodity directive.  This works similarly to account  error  checking,
+       see the notes there for more details.
+
+   Default commodity
+       The D directive sets a default commodity, to be used for any subsequent
+       commodityless amounts (ie, plain numbers) seen while parsing the  jour-
+       nal.   This  effect lasts until the next D directive, or the end of the
+       journal.
+
+       For compatibility/historical reasons, D  also  acts  like  a  commodity
+       directive (setting the commodity's decimal mark for parsing and display
+       style for output).
+
+       As with commodity, the amount  must  include  a  decimal  mark  (either
+       period  or comma).  If both commodity and D directives are used for the
+       same commodity, the commodity style takes precedence.
+
+       The syntax is D AMOUNT.  Eg:
+
+              ; commodity-less amounts should be treated as dollars
+              ; (and displayed with the dollar sign on the left, thousands separators and two decimal places)
+              D $1,000.00
+
+              1/1
+                a     5  ; <- commodity-less amount, parsed as $5 and displayed as $5.00
+                b
+
+   Declaring market prices
+       The P directive declares a market price,  which  is  an  exchange  rate
+       between two commodities on a certain date.  (In Ledger, they are called
+       "historical prices".) These are often obtained from a  stock  exchange,
+       cryptocurrency exchange, or the foreign exchange market.
+
+       The format is:
+
+              P DATE COMMODITY1SYMBOL COMMODITY2AMOUNT
+
+       DATE  is a simple date, COMMODITY1SYMBOL is the symbol of the commodity
+       being priced, and COMMODITY2AMOUNT is the amount (symbol and  quantity)
+       of  commodity  2  that  one  unit of commodity 1 is worth on this date.
+       Examples:
+
+              # one euro was worth $1.35 from 2009-01-01 onward:
+              P 2009-01-01 EUR $1.35
+
+              # and $1.40 from 2010-01-01 onward:
+              P 2010-01-01 EUR $1.40
+
+       The -V, -X and --value flags use these market  prices  to  show  amount
+       values in another commodity.  See Valuation.
+
+   Declaring accounts
+       account directives can be used to declare accounts (ie, the places that
+       amounts are transferred from and to).  Though not required, these  dec-
+       larations can provide several benefits:
+
+       o They can document your intended chart of accounts, providing a refer-
+         ence.
+
+       o They can help hledger know your accounts'  types  (asset,  liability,
+         equity,  revenue,  expense), useful for reports like balancesheet and
+         incomestatement.
+
+       o They control account display order in  reports,  allowing  non-alpha-
+         betic sorting (eg Revenues to appear above Expenses).
+
+       o They  can  store  extra  information about accounts (account numbers,
+         notes, etc.)
+
+       o They help with account name completion in the add  command,  hledger-
+         iadd, hledger-web, ledger-mode etc.
+
+       o In  strict  mode,  they  restrict  which accounts may be posted to by
+         transactions, which helps detect typos.
+
+       The simplest form is just the word account followed by a  hledger-style
+       account name, eg this account directive declares the assets:bank:check-
+       ing account:
+
+              account assets:bank:checking
+
+   Account error checking
+       By default, accounts come into existence when a transaction  references
+       them  by name.  This is convenient, but it means hledger can't warn you
+       when you mis-spell an account name in the journal.  Usually you'll find
+       the  error  later, as an extra account in balance reports, or an incor-
+       rect balance when reconciling.
+
+       In strict mode, enabled with the -s/--strict flag, hledger will  report
+       an  error  if  any  transaction  uses an account name that has not been
+       declared by an account directive.  Some notes:
+
+       o The declaration is case-sensitive; transactions must use the  correct
+         account name capitalisation.
+
+       o The  account  directive's scope is "whole file and below" (see direc-
+         tives).  This means it affects all of the current file, and any files
+         it  includes,  but  not  parent  or  sibling  files.  The position of
+         account directives within the file does not matter, though it's usual
+         to put them at the top.
+
+       o Accounts  can  only  be  declared  in  journal files (but will affect
+         included files in other formats).
+
+       o It's currently not possible to  declare  "all  possible  subaccounts"
+         with a wildcard; every account posted to must be declared.
+
+   Account comments
+       Comments, beginning with a semicolon, can be added:
+
+       o on  the  same line, after two or more spaces (because ; is allowed in
+         account names)
+
+       o on the next lines, indented
+
+       An example of both:
+
+              account assets:bank:checking  ; same-line comment, note 2+ spaces before ;
+                ; next-line comment
+                ; another with tag, acctno:12345 (not used yet)
+
+       Same-line comments are not supported by Ledger, or hledger <1.13.
+
+   Account subdirectives
+       We also allow (and ignore) Ledger-style  indented  subdirectives,  just
+       for compatibility.:
+
+              account assets:bank:checking
+                format blah blah  ; <- subdirective, ignored
+
+       Here is the full syntax of account directives:
+
+              account ACCTNAME  [ACCTTYPE] [;COMMENT]
+                [;COMMENTS]
+                [LEDGER-STYLE SUBDIRECTIVES, IGNORED]
+
+   Account types
+       hledger  recognises  five  main  types of account, corresponding to the
+       account classes in the accounting equation:
+
+       Asset, Liability, Equity, Revenue, Expense.
+
+       These account types are important for controlling which accounts appear
+       in  the  balancesheet, balancesheetequity, incomestatement reports (and
+       probably for other things in future).
+
+       Additionally, we recognise the Cash type, which is also an  Asset,  and
+       which  causes  accounts to appear in the cashflow report.  ("Cash" here
+       means liquid assets, eg bank balances but typically not investments  or
+       receivables.)
+
+   Declaring account types
+       Generally, to make these reports work you should declare your top-level
+       accounts and their types, using account directives with type: tags.
+
+       The tag's value should be one of: Asset,  Liability,  Equity,  Revenue,
+       Expense,  Cash,  A,  L, E, R, X, C (all case insensitive).  The type is
+       inherited by all subaccounts except where they override it.   Here's  a
+       complete example:
+
+              account assets       ; type: Asset
+              account assets:bank  ; type: Cash
+              account assets:cash  ; type: Cash
+              account liabilities  ; type: Liability
+              account equity       ; type: Equity
+              account revenues     ; type: Revenue
+              account expenses     ; type: Expense
+
+   Auto-detected account types
+       If  you  happen  to use common english top-level account names, you may
+       not need to declare account types, as they will be  detected  automati-
+       cally using the following rules:
+
+               If account's name matches this regular expression:                 | its type is:
+              ------------------------------------------------------------------- | ------------
+               ^assets?(:|$)                                                      |
+                 and does not contain regexp (investment|receivable|:A/R|:fixed)  | Cash
+                 otherwise                                                        | Asset
+               ^(debts?|liabilit(y|ies))(:|$)                                     | Liability
+               ^equity(:|$)                                                       | Equity
+               ^(income|revenue)s?(:|$)                                           | Revenue
+               ^expenses?(:|$)                                                    | Expense
+
+       Even so, explicit declarations may be a good idea, for clarity and pre-
+       dictability.
+
+   Interference from auto-detected account types
+       If you assign any account type, it's a good idea to assign all of them,
+       to  prevent any confusion from mixing declared and auto-detected types.
+       Although it's unlikely to happen in real life, here's an example:  with
+       the  following  journal, balancesheetequity shows "liabilities" in both
+       Liabilities  and  Equity  sections.   Declaring  another   account   as
+       type:Liability would fix it:
+
+              account liabilities  ; type:Equity
+
+              2020-01-01
+                assets        1
+                liabilities   1
+                equity       -2
+
+   Old account type syntax
+       In  some  hledger  journals  you might instead see this old syntax (the
+       letters ALERX, separated from the account name by two or more  spaces);
+       this is deprecated and may be removed soon:
+
+              account assets       A
+              account liabilities  L
+              account equity       E
+              account revenues     R
+              account expenses     X
+
+   Account display order
+       Account  directives also set the order in which accounts are displayed,
+       eg in reports, the hledger-ui  accounts  screen,  and  the  hledger-web
+       sidebar.  By default accounts are listed in alphabetical order.  But if
+       you have these account directives in the journal:
+
+              account assets
+              account liabilities
+              account equity
+              account revenues
+              account expenses
+
+       you'll see those accounts displayed in declaration order, not alphabet-
+       ically:
+
+              $ hledger accounts -1
+              assets
+              liabilities
+              equity
+              revenues
+              expenses
+
+       Undeclared accounts, if any, are displayed last, in alphabetical order.
+
+       Note that sorting is done at each level of  the  account  tree  (within
+       each  group of sibling accounts under the same parent).  And currently,
+       this directive:
+
+              account other:zoo
+
+       would influence the position of zoo among other's subaccounts, but  not
+       the position of other among the top-level accounts.  This means:
+
+       o you  will  sometimes declare parent accounts (eg account other above)
+         that you don't intend to post to, just  to  customize  their  display
+         order
+
+       o sibling  accounts  stay together (you couldn't display x:y in between
+         a:b and a:c).
+
+   Rewriting accounts
+       You can define account alias rules which rewrite your account names, or
+       parts of them, before generating reports.  This can be useful for:
+
+       o expanding shorthand account names to their full form, allowing easier
+         data entry and a less verbose journal
+
+       o adapting old journals to your current chart of accounts
+
+       o experimenting with new account organisations, like a new hierarchy or
+         combining two accounts into one
+
+       o customising reports
+
+       Account aliases also rewrite account names in account directives.  They
+       do not affect account names being entered via hledger add  or  hledger-
+       web.
+
+       See also Rewrite account names.
+
+   Basic aliases
+       To  set an account alias, use the alias directive in your journal file.
+       This affects all subsequent journal entries in the current file or  its
+       included  files  (but  note:  not sibling or parent files).  The spaces
+       around the = are optional:
+
+              alias OLD = NEW
+
+       Or, you can use the --alias 'OLD=NEW' option on the command line.  This
+       affects all entries.  It's useful for trying out aliases interactively.
+
+       OLD and NEW are  case  sensitive  full  account  names.   hledger  will
+       replace  any occurrence of the old account name with the new one.  Sub-
+       accounts are also affected.  Eg:
+
+              alias checking = assets:bank:wells fargo:checking
+              ; rewrites "checking" to "assets:bank:wells fargo:checking", or "checking:a" to "assets:bank:wells fargo:checking:a"
+
+   Regex aliases
+       There is also a more powerful variant that uses a  regular  expression,
+       indicated by the forward slashes:
+
+              alias /REGEX/ = REPLACEMENT
+
+       or --alias '/REGEX/=REPLACEMENT'.
+
+       REGEX  is  a  case-insensitive regular expression.  Anywhere it matches
+       inside an account name, the matched part will be replaced  by  REPLACE-
+       MENT.   If REGEX contains parenthesised match groups, these can be ref-
+       erenced by the usual numeric backreferences in REPLACEMENT.  Eg:
+
+              alias /^(.+):bank:([^:]+):(.*)/ = \1:\2 \3
+              ; rewrites "assets:bank:wells fargo:checking" to  "assets:wells fargo checking"
+
+       Also note that REPLACEMENT continues to the end of line (or on  command
+       line,  to  end  of  option argument), so it can contain trailing white-
+       space.
+
+   Combining aliases
+       You can define as many aliases as you like,  using  journal  directives
+       and/or command line options.
+
+       Recursive  aliases  -  where an account name is rewritten by one alias,
+       then by another alias, and so on - are allowed.  Each  alias  sees  the
+       effect of previously applied aliases.
+
+       In  such  cases it can be important to understand which aliases will be
+       applied and in which order.  For (each account name  in)  each  journal
+       entry, we apply:
+
+       1. alias  directives  preceding the journal entry, most recently parsed
+          first (ie, reading upward from the journal entry, bottom to top)
+
+       2. --alias options, in the order they  appeared  on  the  command  line
+          (left to right).
+
+       In other words, for (an account name in) a given journal entry:
+
+       o the nearest alias declaration before/above the entry is applied first
+
+       o the next alias before/above that will be be applied next, and so on
+
+       o aliases defined after/below the entry do not affect it.
+
+       This gives nearby aliases precedence over distant ones, and helps  pro-
+       vide  semantic stability - aliases will keep working the same way inde-
+       pendent of which files are being read and in which order.
+
+       In case of trouble, adding --debug=6 to  the  command  line  will  show
+       which aliases are being applied when.
+
+   Aliases and multiple files
+       As  explained at Directives and multiple files, alias directives do not
+       affect parent or sibling files.  Eg in this command,
+
+              hledger -f a.aliases -f b.journal
+
+       account  aliases  defined  in  a.aliases  will  not  affect  b.journal.
+       Including the aliases doesn't work either:
+
+              include a.aliases
+
+              2020-01-01  ; not affected by a.aliases
+                foo  1
+                bar
+
+       This means that account aliases should usually be declared at the start
+       of your top-most file, like this:
+
+              alias foo=Foo
+              alias bar=Bar
+
+              2020-01-01  ; affected by aliases above
+                foo  1
+                bar
+
+              include c.journal  ; also affected
+
+   end aliases
+       You can clear (forget) all  currently  defined  aliases  with  the  end
+       aliases directive:
+
+              end aliases
+
+   Default parent account
+       You  can  specify  a  parent  account  which  will  be prepended to all
+       accounts within a section of the journal.  Use the  apply  account  and
+       end apply account directives like so:
+
+              apply account home
+
+              2010/1/1
+                  food    $10
+                  cash
+
+              end apply account
+
+       which is equivalent to:
+
+              2010/01/01
+                  home:food           $10
+                  home:cash          $-10
+
+       If  end  apply  account  is omitted, the effect lasts to the end of the
+       file.  Included files are also affected, eg:
+
+              apply account business
+              include biz.journal
+              end apply account
+              apply account personal
+              include personal.journal
+
+       Prior to hledger 1.0, legacy account and end spellings were  also  sup-
+       ported.
+
+       A  default parent account also affects account directives.  It does not
+       affect account names being entered via hledger add or hledger-web.   If
+       account  aliases are present, they are applied after the default parent
+       account.
+
+   Periodic transactions
+       Periodic transaction rules  describe  transactions  that  recur.   They
+       allow  hledger  to  generate temporary future transactions to help with
+       forecasting, so you don't have to write out each one  in  the  journal,
+       and it's easy to try out different forecasts.
+
+       Periodic  transactions  can be a little tricky, so before you use them,
+       read this whole section - or at least these tips:
+
+       1. Two spaces accidentally added or omitted will cause  you  trouble  -
+          read about this below.
+
+       2. For  troubleshooting,  show  the generated transactions with hledger
+          print  --forecast  tag:generated  or  hledger  register   --forecast
+          tag:generated.
+
+       3. Forecasted  transactions  will  begin  only after the last non-fore-
+          casted transaction's date.
+
+       4. Forecasted transactions will end 6 months from  today,  by  default.
+          See below for the exact start/end rules.
+
+       5. period   expressions  can  be  tricky.   Their  documentation  needs
+          improvement, but is worth studying.
+
+       6. Some period expressions with a repeating interval must  begin  on  a
+          natural  boundary  of  that  interval.  Eg in weekly from DATE, DATE
+          must be a monday.  ~ weekly from 2019/10/1 (a tuesday) will give  an
+          error.
+
+       7. Other period expressions with an interval are automatically expanded
+          to cover a whole number of that interval.  (This is done to  improve
+          reports, but it also affects periodic transactions.  Yes, it's a bit
+          inconsistent with the above.) Eg: ~ every 10th  day  of  month  from
+          2020/01,  which  is  equivalent  to  ~  every 10th day of month from
+          2020/01/01, will be adjusted to start on 2019/12/10.
+
+       Periodic transaction rules also have a second meaning: they are used to
+       define budget goals, shown in budget reports.
+
+   Periodic rule syntax
+       A periodic transaction rule looks like a normal journal entry, with the
+       date replaced by a tilde (~) followed by a period expression (mnemonic:
+       ~ looks like a recurring sine wave.):
+
+              ~ monthly
+                  expenses:rent          $2000
+                  assets:bank:checking
+
+       There  is  an additional constraint on the period expression: the start
+       date must fall on a natural boundary of the interval.  Eg monthly  from
+       2018/1/1 is valid, but monthly from 2018/1/15 is not.
+
+       Partial  or  relative dates (M/D, D, tomorrow, last week) in the period
+       expression can work (useful or not).  They will be relative to  today's
+       date,  unless  a  Y  default year directive is in effect, in which case
+       they will be relative to Y/1/1.
+
+   Two spaces between period expression and description!
+       If the period expression is  followed  by  a  transaction  description,
+       these must be separated by two or more spaces.  This helps hledger know
+       where the period expression ends, so that descriptions can not acciden-
+       tally alter their meaning, as in this example:
+
+              ; 2 or more spaces needed here, so the period is not understood as "every 2 months in 2020"
+              ;               ||
+              ;               vv
+              ~ every 2 months  in 2020, we will review
+                  assets:bank:checking   $1500
+                  income:acme inc
+
+       So,
+
+       o Do  write two spaces between your period expression and your transac-
+         tion description, if any.
+
+       o Don't accidentally write two spaces in  the  middle  of  your  period
+         expression.
+
+   Forecasting with periodic transactions
+       The  --forecast  flag  activates  any periodic transaction rules in the
+       journal.  They will generate temporary  recurring  transactions,  which
+       are  not  saved  in  the  journal,  but  will appear in all reports (eg
+       print).  This can be useful for estimating balances into the future, or
+       experimenting  with  different scenarios.  Or, it can be used as a data
+       entry aid: describe recurring transactions, and every so often copy the
+       output of print --forecast into the journal.
+
+       These  transactions  will  have  an extra tag indicating which periodic
+       rule generated them: generated-transaction:~ PERIODICEXPR.  And a simi-
+       lar,  hidden  tag  (beginning  with  an underscore) which, because it's
+       never displayed by print, can be used to match  transactions  generated
+       "just now": _generated-transaction:~ PERIODICEXPR.
+
+       Periodic  transactions  are  generated within some forecast period.  By
+       default, this
+
+       o begins on the later of
+
+         o the report start date if specified with -b/-p/date:
+
+         o the day after the latest normal (non-periodic) transaction  in  the
+           journal, or today if there are no normal transactions.
+
+       o ends  on  the  report  end  date  if specified with -e/-p/date:, or 6
+         months (180 days) from today.
+
+       This means that periodic transactions will begin only after the  latest
+       recorded  transaction.   And a recorded transaction dated in the future
+       can prevent generation of periodic transactions.  (You can  avoid  that
+       by writing the future transaction as a one-time periodic rule instead -
+       put tilde before the date, eg ~ YYYY-MM-DD ...).
+
+       Or, you can set your own arbitrary "forecast period", which can overlap
+       recorded  transactions,  and need not be in the future, by providing an
+       option argument, like --forecast=PERIODEXPR.  Note the equals  sign  is
+       required, a space won't work.  PERIODEXPR is a period expression, which
+       can specify the start date, end date, or both, like in a  date:  query.
+       (See  also  hledger.1  ->  Report  start  &  end date).  Some examples:
+       --forecast=202001-202004, --forecast=jan-, --forecast=2020.
+
+   Budgeting with periodic transactions
+       With the --budget flag, currently supported  by  the  balance  command,
+       each  periodic transaction rule declares recurring budget goals for the
+       specified accounts.  Eg the first example  above  declares  a  goal  of
+       spending  $2000  on  rent  (and  also,  a goal of depositing $2000 into
+       checking) every month.  Goals and actual performance can then  be  com-
+       pared in budget reports.
+
+       See also: Budgeting and Forecasting.
+
+
+   Auto postings
+       "Automated  postings"  or  "auto postings" are extra postings which get
+       added  automatically  to  transactions  which  match  certain  queries,
+       defined by "auto posting rules", when you use the --auto flag.
+
+       An auto posting rule looks a bit like a transaction:
+
+              = QUERY
+                  ACCOUNT  AMOUNT
+                  ...
+                  ACCOUNT  [AMOUNT]
+
+       except  the  first  line is an equals sign (mnemonic: = suggests match-
+       ing), followed by a query (which matches existing postings),  and  each
+       "posting"  line  describes  a  posting to be generated, and the posting
+       amounts can be:
+
+       o a normal amount with a commodity symbol, eg $2.  This  will  be  used
+         as-is.
+
+       o a number, eg 2.  The commodity symbol (if any) from the matched post-
+         ing will be added to this.
+
+       o a numeric multiplier, eg *2 (a star followed by  a  number  N).   The
+         matched posting's amount (and total price, if any) will be multiplied
+         by N.
+
+       o a multiplier with a commodity symbol, eg *$2 (a star, number  N,  and
+         symbol S).  The matched posting's amount will be multiplied by N, and
+         its commodity symbol will be replaced with S.
+
+       Any query term containing spaces must be enclosed in single  or  double
+       quotes,  as on the command line.  Eg, note the quotes around the second
+       query term below:
+
+              = expenses:groceries 'expenses:dining out'
+                  (budget:funds:dining out)                 *-1
+
+       Some examples:
+
+              ; every time I buy food, schedule a dollar donation
+              = expenses:food
+                  (liabilities:charity)   $-1
+
+              ; when I buy a gift, also deduct that amount from a budget envelope subaccount
+              = expenses:gifts
+                  assets:checking:gifts  *-1
+                  assets:checking         *1
+
+              2017/12/1
+                expenses:food    $10
+                assets:checking
+
+              2017/12/14
+                expenses:gifts   $20
+                assets:checking
+
+              $ hledger print --auto
+              2017-12-01
+                  expenses:food              $10
+                  assets:checking
+                  (liabilities:charity)      $-1
+
+              2017-12-14
+                  expenses:gifts             $20
+                  assets:checking
+                  assets:checking:gifts     -$20
+                  assets:checking            $20
+
+   Auto postings and multiple files
+       An auto posting rule can affect any transaction in the current file, or
+       in  any  parent file or child file.  Note, currently it will not affect
+       sibling files (when multiple -f/--file are used - see #1212).
+
+   Auto postings and dates
+       A posting date (or secondary date) in the matched posting,  or  (taking
+       precedence)  a  posting date in the auto posting rule itself, will also
+       be used in the generated posting.
+
+   Auto postings and transaction balancing / inferred amounts / balance asser-
+       tions
+       Currently, auto postings are added:
+
+       o after  missing amounts are inferred, and transactions are checked for
+         balancedness,
+
+       o but before balance assertions are checked.
+
+       Note this means that journal entries must be balanced both  before  and
+       after auto postings are added.  This changed in hledger 1.12+; see #893
+       for background.
+
+   Auto posting tags
+       Automated postings will have some extra tags:
+
+       o generated-posting:= QUERY - shows this was generated by an auto post-
+         ing rule, and the query
+
+       o _generated-posting:=  QUERY  - a hidden tag, which does not appear in
+         hledger's output.  This can be used to match postings generated "just
+         now", rather than generated in the past and saved to the journal.
+
+       Also,  any transaction that has been changed by auto posting rules will
+       have these tags added:
+
+       o modified: - this transaction was modified
+
+       o _modified: - a hidden tag not appearing in the comment; this transac-
+         tion was modified "just now".
+
+CSV FORMAT
+       How hledger reads CSV data, and the CSV rules file format.
+
+       hledger  can read CSV files (Character Separated Value - usually comma,
+       semicolon, or tab) containing dated records as  if  they  were  journal
+       files, automatically converting each CSV record into a transaction.
+
+       (To learn about writing CSV, see CSV output.)
+
+       We describe each CSV file's format with a corresponding rules file.  By
+       default this is named like the CSV file with a .rules extension  added.
+       Eg  when reading FILE.csv, hledger also looks for FILE.csv.rules in the
+       same directory as FILE.csv.  You can specify  a  different  rules  file
+       with  the  --rules-file  option.  If a rules file is not found, hledger
+       will create a sample rules file, which you'll need to adjust.
+
+       This file contains rules describing the CSV data (header  line,  fields
+       layout, date format etc.), and how to construct hledger journal entries
+       (transactions) from it.  Often there will also be a list of conditional
+       rules  for  categorising  transactions  based  on  their  descriptions.
+       Here's an overview of the CSV rules; these  are  described  more  fully
+       below, after the examples:
+
+
+       skip                         skip one or more header lines or matched CSV
+                                    records
+       fields list                  name CSV  fields,  assign  them  to  hledger
+                                    fields
+       field assignment             assign  a  value  to one hledger field, with
+                                    interpolation
+       Field names                  hledger field names, used in the fields list
+                                    and field assignments
+       separator                    a custom field separator
+
+       if block                     apply  some  rules to CSV records matched by
+                                    patterns
+       if table                     apply some rules to CSV records  matched  by
+                                    patterns, alternate syntax
+       end                          skip the remaining CSV records
+       date-format                  how to parse dates in CSV records
+       decimal-mark                 the  decimal  mark  used  in CSV amounts, if
+                                    ambiguous
+       newest-first                 disambiguate record order when there's  only
+                                    one date
+       include                      inline another CSV rules file
+       balance-type                 choose  which type of balance assignments to
+                                    use
+
+       Note, for best error messages when reading CSV files, use a .csv,  .tsv
+       or .ssv file extension or file prefix - see File Extension below.
+
+       There's an introductory Convert CSV files tutorial on hledger.org.
+
+   Examples
+       Here  are  some sample hledger CSV rules files.  See also the full col-
+       lection at:
+       https://github.com/simonmichael/hledger/tree/master/examples/csv
+
+   Basic
+       At minimum, the rules file must identify the date  and  amount  fields,
+       and  often  it also specifies the date format and how many header lines
+       there are.  Here's a simple CSV file and a rules file for it:
+
+              Date, Description, Id, Amount
+              12/11/2019, Foo, 123, 10.23
+
+              # basic.csv.rules
+              skip         1
+              fields       date, description, _, amount
+              date-format  %d/%m/%Y
+
+              $ hledger print -f basic.csv
+              2019-11-12 Foo
+                  expenses:unknown           10.23
+                  income:unknown            -10.23
+
+       Default account names are chosen, since we didn't set them.
+
+   Bank of Ireland
+       Here's a CSV with two amount fields (Debit and Credit), and  a  balance
+       field,  which we can use to add balance assertions, which is not neces-
+       sary but provides extra error checking:
+
+              Date,Details,Debit,Credit,Balance
+              07/12/2012,LODGMENT       529898,,10.0,131.21
+              07/12/2012,PAYMENT,5,,126
+
+              # bankofireland-checking.csv.rules
+
+              # skip the header line
+              skip
+
+              # name the csv fields, and assign some of them as journal entry fields
+              fields  date, description, amount-out, amount-in, balance
+
+              # We generate balance assertions by assigning to "balance"
+              # above, but you may sometimes need to remove these because:
+              #
+              # - the CSV balance differs from the true balance,
+              #   by up to 0.0000000000005 in my experience
+              #
+              # - it is sometimes calculated based on non-chronological ordering,
+              #   eg when multiple transactions clear on the same day
+
+              # date is in UK/Ireland format
+              date-format  %d/%m/%Y
+
+              # set the currency
+              currency  EUR
+
+              # set the base account for all txns
+              account1  assets:bank:boi:checking
+
+              $ hledger -f bankofireland-checking.csv print
+              2012-12-07 LODGMENT       529898
+                  assets:bank:boi:checking         EUR10.0 = EUR131.2

+                  expenses:unknown                  EUR5.0
+
+       The balance assertions don't raise an error above, because we're  read-
+       ing  directly  from  CSV, but they will be checked if these entries are
+       imported into a journal file.
+

+       Here we convert amazon.com order history, and use an if block to gener-
+       ate  a third posting if there's a fee.  (In practice you'd probably get
+       this data from your bank instead, but it's an example.)

+   CSV rules
+       The following kinds of rule can appear in the rules file, in any order.
+       Blank lines and lines beginning with # or ; are ignored.
+
+   skip
+              skip N
+
+       The word "skip" followed by a number (or no number,  meaning  1)  tells
+       hledger  to  ignore  this  many non-empty lines preceding the CSV data.
+       (Empty/blank lines are skipped automatically.) You'll need  this  when-
+       ever your CSV data contains header lines.
+
+       It also has a second purpose: it can be used inside if blocks to ignore
+       certain CSV records (described below).
+
+   fields list
+              fields FIELDNAME1, FIELDNAME2, ...
+
+       A fields list (the word  "fields"  followed  by  comma-separated  field
+       names)  is  the quick way to assign CSV field values to hledger fields.
+       (The other way is field assignments, see below.)  A  fields  list  does
+       does two things:
+
+       1. It  names  the  CSV fields.  This is optional, but can be convenient
+          later for interpolating them.
+
+       2. Whenever you use a standard hledger field name (defined below),  the
+          CSV value is assigned to that part of the hledger transaction.
+
+       Here's  an  example  that  says "use the 1st, 2nd and 4th fields as the
+       transaction's date, description and amount; name the  last  two  fields
+       for later reference; and ignore the others":
+
+              fields date, description, , amount, , , somefield, anotherfield
+
+       Tips:
+
+       o The fields list always use commas, even if your CSV data uses another
+         separator character.
+
+       o Currently there must be least two items in the  list  (at  least  one
+         comma).
+
+       o Field  names may not contain spaces.  Spaces before/after field names
+         are optional.
+
+       o If the CSV contains column headings, it's a good idea to  use  these,
+         suitably modified, as the basis for your field names (eg lower-cased,
+         with underscores instead of spaces).
+
+       o If some heading names match standard hledger fields,  but  you  don't
+         want  to  set  the  hledger fields directly, alter those names, eg by
+         appending an underscore.
+
+       o Fields you don't care about can be given a dummy name (eg: _ ), or no
+         name.
+
+   field assignment
+              HLEDGERFIELDNAME FIELDVALUE
+
+       Field  assignments  are  the  more flexible way to assign CSV values to
+       hledger fields.  They can be used instead of or in addition to a fields
+       list (see above).
+
+       To  assign a value to a hledger field, write the field name (any of the
+       standard hledger field/pseudo-field names,  defined  below),  a  space,
+       followed  by a text value on the same line.  This text value may inter-
+       polate CSV fields, referenced by their  1-based  position  in  the  CSV
+       record  (%N),  or by the name they were given in the fields list (%CSV-
+       FIELDNAME).
+
+       Some examples:
+
+              # set the amount to the 4th CSV field, with " USD" appended
+              amount %4 USD
+
+              # combine three fields to make a comment, containing note: and date: tags
+              comment note: %somefield - %anotherfield, date: %1
+
+       Tips:
+
+       o Interpolation strips outer whitespace (so a CSV  value  like  "  1  "
+         becomes 1 when interpolated) (#1051).
+
+       o See also Tips below.
+
+   Field names
+       Here are the standard hledger field (and pseudo-field) names, which you
+       can use in a fields list and in field assignments.  For more about  the
+       transaction parts they refer to, see Transactions.
+
+   date field
+       Assigning to date sets the transaction date.
+
+   date2 field
+       date2 sets the transaction's secondary date, if any.
+
+   status field
+       status sets the transaction's status, if any.
+
+   code field
+       code sets the transaction's code, if any.
+
+   description field
+       description sets the transaction's description, if any.
+
+   comment field
+       comment sets the transaction's comment, if any.
+
+       commentN, where N is a number, sets the Nth posting's comment.
+
+       Tips: - Only single-line comments can be assigned.  - Comments can con-
+       tain tags, as usual.
+
+   account field
+       Assigning to accountN, where N is 1 to 99, sets the account name of the
+       Nth posting, and causes that posting to be generated.
+
+       Most  often  there are two postings, so you'll want to set account1 and
+       account2.  Typically account1 is associated with the CSV file,  and  is
+       set  once  with  a top-level assignment, while account2 is set based on
+       each transaction's description, and in conditional blocks.
+
+       If a posting's account name is left unset but its amount  is  set  (see
+       below),  a default account name will be chosen (like "expenses:unknown"
+       or "income:unknown").
+
+   amount field
+       amountN sets the amount of the Nth posting, and causes that posting  to
+       be  generated.   By  assigning  to amount1, amount2, ...  etc.  you can
+       generate up to 99 postings.
+
+       amountN-in and amountN-out can be used instead, if the CSV  uses  sepa-
+       rate  fields  for  debits  and credits (inflows and outflows).  hledger
+       assumes both of these CSV fields are unsigned, and  will  automatically
+       negate  the  "-out"  value.   If they are signed, see "Setting amounts"
+       below.
+
+       amount, or amount-in and amount-out are a legacy  mode,  to  keep  pre-
+       hledger-1.17  CSV rules files working (and for occasional convenience).
+       They are suitable only for  two-posting  transactions;  they  set  both
+       posting  1's  and  posting  2's  amount.   Posting  2's  amount will be
+       negated, and also converted to cost if there's a transaction price.
+
+       If you have an existing rules file using the unnumbered form, you might
+       want  to  use  the numbered form in certain conditional blocks, without
+       having to update and retest all the old  rules.   To  facilitate  this,
+       posting    1    ignores    amount/amount-in/amount-out    if   any   of
+       amount1/amount1-in/amount1-out are assigned, and posting 2 ignores them
+       if  any  of  amount2/amount2-in/amount2-out are assigned, avoiding con-
+       flicts.
+
+   currency field
+       currency sets a currency symbol,  to  be  prepended  to  all  postings'
+       amounts.   You  can  use this if the CSV amounts do not have a currency
+       symbol, eg if it is in a separate column.
+
+       currencyN prepends a currency symbol to just the Nth posting's  amount.
+
+   balance field
+       balanceN  sets  a balance assertion amount (or if the posting amount is
+       left empty, a balance assignment) on posting N.
+
+       balance is a compatibility spelling for hledger <1.17; it is equivalent
+       to balance1.
+
+       You  can  adjust the type of assertion/assignment with the balance-type
+       rule (see below).
+
+       See Tips below for more about setting amounts and currency.
+
+   separator
+       You can use the separator rule to read other kinds  of  character-sepa-
+       rated  data.   The  argument  is any single separator character, or the
+       words tab or space (case insensitive).  Eg, for comma-separated  values
+       (CSV):
+
+              separator ,
+
+       or for semicolon-separated values (SSV):
+
+              separator ;
+
+       or for tab-separated values (TSV):
+
+              separator TAB
+
+       If  the  input file has a .csv, .ssv or .tsv file extension (or a csv:,
+       ssv:, tsv: prefix), the appropriate separator will be inferred automat-
+       ically, and you won't need this rule.
+
+   if block
+              if MATCHER
+               RULE
+
+              if
+              MATCHER
+              MATCHER
+              MATCHER
+               RULE
+               RULE
+
+       Conditional  blocks ("if blocks") are a block of rules that are applied
+       only to CSV records which match certain patterns.  They are often  used
+       for customising account names based on transaction descriptions.
+
+   Matching the whole record
+       Each MATCHER can be a record matcher, which looks like this:
+
+              REGEX
+
+       REGEX is a case-insensitive regular expression that tries to match any-
+       where within the CSV record.  It  is  a  POSIX  ERE  (extended  regular
+       expression)  that  also  supports GNU word boundaries (\b, \B, \<, \>),
+       and nothing else.  If you have trouble,  be  sure  to  check  our  doc:
+       https://hledger.org/hledger.html#regular-expressions
+
+       Important  note: the record that is matched is not the original record,
+       but a synthetic one, with any enclosing double quotes (but not  enclos-
+       ing whitespace) removed, and always comma-separated (which means that a
+       field containing a comma will appear like  two  fields).   Eg,  if  the
+       original  record  is  2020-01-01;  "Acme, Inc.";  1,000, the REGEX will
+       actually see 2020-01-01,Acme, Inc.,  1,000).
+
+   Matching individual fields
+       Or, MATCHER can be a field matcher, like this:
+
+              %CSVFIELD REGEX
+
+       which matches just the content of a particular CSV field.  CSVFIELD  is
+       a  percent  sign  followed  by  the field's name or column number, like
+       %date or %1.
+
+   Combining matchers
+       A single matcher can be written on the same line as the "if"; or multi-
+       ple matchers can be written on the following lines, non-indented.  Mul-
+       tiple matchers are OR'd (any one of them can match), unless one  begins
+       with an & symbol, in which case it is AND'ed with the previous matcher.
+
+              if
+              MATCHER
+              & MATCHER
+               RULE
+
+   Rules applied on successful match
+       After the patterns there should be one or  more  rules  to  apply,  all
+       indented  by  at  least  one space.  Three kinds of rule are allowed in
+       conditional blocks:
+
+       o field assignments (to set a hledger field)
+
+       o skip (to skip the matched CSV record)
+
+       o end (to skip all remaining CSV records).
+
+       Examples:
+
+              # if the CSV record contains "groceries", set account2 to "expenses:groceries"
+              if groceries
+               account2 expenses:groceries
+
+              # if the CSV record contains any of these patterns, set account2 and comment as shown
+              if
+              monthly service fee
+              atm transaction fee
+              banking thru software
+               account2 expenses:business:banking
+               comment  XXX deductible ? check it
+
+   if table
+              if,CSVFIELDNAME1,CSVFIELDNAME2,...,CSVFIELDNAMEn
+              MATCHER1,VALUE11,VALUE12,...,VALUE1n
+              MATCHER2,VALUE21,VALUE22,...,VALUE2n
+              MATCHER3,VALUE31,VALUE32,...,VALUE3n
+              <empty line>
+
+       Conditional tables ("if tables") are  a  different  syntax  to  specify
+       field  assignments that will be applied only to CSV records which match
+       certain patterns.
+
+       MATCHER could be either field or record matcher,  as  described  above.
+       When MATCHER matches, values from that row would be assigned to the CSV
+       fields named on the if line, in the same order.
+
+       Therefore if table is exactly equivalent to a sequence of of if blocks:
+
+              if MATCHER1
+                CSVFIELDNAME1 VALUE11
+                CSVFIELDNAME2 VALUE12
+                ...
+                CSVFIELDNAMEn VALUE1n
+
+              if MATCHER2
+                CSVFIELDNAME1 VALUE21
+                CSVFIELDNAME2 VALUE22
+                ...
+                CSVFIELDNAMEn VALUE2n
+
+              if MATCHER3
+                CSVFIELDNAME1 VALUE31
+                CSVFIELDNAME2 VALUE32
+                ...
+                CSVFIELDNAMEn VALUE3n
+
+       Each  line starting with MATCHER should contain enough (possibly empty)
+       values for all the listed fields.
+
+       Rules would be checked and applied in the order they are listed in  the
+       table and, like with if blocks, later rules (in the same or another ta-
+       ble) or if blocks could override the effect of any rule.
+
+       Instead of ',' you can use a variety of other non-alphanumeric  charac-
+       ters as a separator.  First character after if is taken to be the sepa-
+       rator for the rest of the table.  It is the responsibility of the  user
+       to  ensure  that  separator does not occur inside MATCHERs and values -
+       there is no way to escape separator.
+
+       Example:
+
+              if,account2,comment
+              atm transaction fee,expenses:business:banking,deductible? check it
+              %description groceries,expenses:groceries,
+              2020/01/12.*Plumbing LLC,expenses:house:upkeep,emergency plumbing call-out
+
+   end
+       This rule can be used inside if blocks (only),  to  make  hledger  stop
+       reading this CSV file and move on to the next input file, or to command
+       execution.  Eg:
+
+              # ignore everything following the first empty record
+              if ,,,,
+               end
+
+   date-format
+              date-format DATEFMT
+
+       This is a helper for the date (and date2) fields.  If  your  CSV  dates
+       are  not  formatted  like  YYYY-MM-DD, YYYY/MM/DD or YYYY.MM.DD, you'll
+       need to add a date-format rule describing them  with  a  strptime  date
+       parsing  pattern, which must parse the CSV date value completely.  Some
+       examples:
+
+              # MM/DD/YY
+              date-format %m/%d/%y
+
+              # D/M/YYYY
+              # The - makes leading zeros optional.
+              date-format %-d/%-m/%Y
+
+              # YYYY-Mmm-DD
+              date-format %Y-%h-%d
+
+              # M/D/YYYY HH:MM AM some other junk
+              # Note the time and junk must be fully parsed, though only the date is used.
+              date-format %-m/%-d/%Y %l:%M %p some other junk
+
+       For the supported strptime syntax, see:
+       https://hackage.haskell.org/package/time/docs/Data-Time-For-
+       mat.html#v:formatTime
+
+       Note  that although you can parse date-times which include a time zone,
+       that time zone is ignored; it will not change the date that is  parsed.
+       This  means  when  reading  CSV  data with times not in your local time
+       zone, dates can be "off by one".
+
+   decimal-mark
+              decimal-mark .
+
+       or:
+
+              decimal-mark ,
+
+       hledger automatically accepts either period or comma as a decimal  mark
+       when  parsing  numbers (cf Amounts).  However if any numbers in the CSV
+       contain digit group marks,  such  as  thousand-separating  commas,  you
+       should  declare  the  decimal  mark explicitly with this rule, to avoid
+       misparsed numbers.
+
+   newest-first
+       hledger always sorts the generated transactions by date.   Transactions
+       on  the same date should appear in the same order as their CSV records,
+       as hledger can usually auto-detect whether the CSV's  normal  order  is
+       oldest first or newest first.  But if all of the following are true:
+
+       o the  CSV  might  sometimes  contain just one day of data (all records
+         having the same date)
+
+       o the CSV records are normally in reverse chronological  order  (newest
+         at the top)
+
+       o and you care about preserving the order of same-day transactions
+
+       then, you should add the newest-first rule as a hint.  Eg:
+
+              # tell hledger explicitly that the CSV is normally newest first
+              newest-first
+
+   include
+              include RULESFILE
+
+       This  includes  the  contents  of another CSV rules file at this point.
+       RULESFILE is an absolute file path or a path relative  to  the  current
+       file's  directory.  This can be useful for sharing common rules between
+       several rules files, eg:
+
+              # someaccount.csv.rules
+
+              ## someaccount-specific rules
+              fields   date,description,amount
+              account1 assets:someaccount
+              account2 expenses:misc
+
+              ## common rules
+              include categorisation.rules
+
+   balance-type
+       Balance assertions generated by assigning to balanceN are of the simple
+       =  type  by  default, which is a single-commodity, subaccount-excluding
+       assertion.  You may find the subaccount-including variants more useful,
+       eg  if  you  have  created some virtual subaccounts of checking to help
+       with budgeting.  You can select a different type of assertion with  the
+       balance-type rule:
+
+              # balance assertions will consider all commodities and all subaccounts
+              balance-type ==*
+
+       Here are the balance assertion types for quick reference:
+
+              =    single commodity, exclude subaccounts
+              =*   single commodity, include subaccounts
+              ==   multi commodity,  exclude subaccounts
+              ==*  multi commodity,  include subaccounts
+
+   Tips
+   Rapid feedback
+       It's  a  good idea to get rapid feedback while creating/troubleshooting
+       CSV rules.  Here's a good way, using entr from http://eradman.com/entr-
+       project :
+
+              $ ls foo.csv* | entr bash -c 'echo ----; hledger -f foo.csv print desc:SOMEDESC'
+
+       A  desc:  query (eg) is used to select just one, or a few, transactions
+       of interest.  "bash -c" is used to run multiple  commands,  so  we  can
+       echo  a  separator  each  time the command re-runs, making it easier to
+       read the output.
+
+   Valid CSV
+       hledger accepts CSV conforming  to  RFC  4180.   When  CSV  values  are
+       enclosed in quotes, note:
+
+       o they must be double quotes (not single quotes)
+
+       o spaces outside the quotes are not allowed
+
+   File Extension
+       To  help hledger identify the format and show the right error messages,
+       CSV/SSV/TSV files should normally be named with a .csv,  .ssv  or  .tsv
+       filename  extension.   Or,  the file path should be prefixed with csv:,
+       ssv: or tsv:.  Eg:
+
+              $ hledger -f foo.ssv print
+
+       or:
+
+              $ cat foo | hledger -f ssv:- foo
+
+       You can override the file extension with a separator  rule  if  needed.
+       See also: Input files in the hledger manual.
+
+   Reading multiple CSV files
+       If  you  use  multiple  -f  options to read multiple CSV files at once,
+       hledger will look for a correspondingly-named rules file for  each  CSV
+       file.   But if you use the --rules-file option, that rules file will be
+       used for all the CSV files.
+
+   Valid transactions
+       After reading a CSV file, hledger post-processes and validates the gen-
+       erated journal entries as it would for a journal file - balancing them,
+       applying balance assignments, and canonicalising  amount  styles.   Any
+       errors  at this stage will be reported in the usual way, displaying the
+       problem entry.
+
+       There is one exception: balance assertions, if you have generated them,
+       will  not  be checked, since normally these will work only when the CSV
+       data is part of the main journal.  If you  do  need  to  check  balance
+       assertions generated from CSV right away, pipe into another hledger:
+
+              $ hledger -f file.csv print | hledger -f- print
+
+   Deduplicating, importing
+       When  you  download a CSV file periodically, eg to get your latest bank
+       transactions, the new file may overlap with  the  old  one,  containing
+       some of the same records.
+
+       The import command will (a) detect the new transactions, and (b) append
+       just those transactions to your main journal.  It is idempotent, so you
+       don't  have to remember how many times you ran it or with which version
+       of the CSV.  (It keeps state in a hidden .latest.FILE.csv  file.)  This
+       is the easiest way to import CSV data.  Eg:
+
+              # download the latest CSV files, then run this command.
+              # Note, no -f flags needed here.
+              $ hledger import *.csv [--dry]
+
+       This  method  works  for  most CSV files.  (Where records have a stable
+       chronological order, and new records appear only at the new end.)
+
+       A number of other tools and workflows, hledger-specific and  otherwise,
+       exist for converting, deduplicating, classifying and managing CSV data.
+       See:

+
+   Setting amounts
+       Some tips on using the amount-setting rules discussed above.
+
+       Here are the ways to set a posting's amount:
+
+       1. If the CSV has a single amount field:
+       Assign (via a fields list or a field assignment) to amountN.  This sets
+       the Nth posting's amount.  N is usually 1 or 2 but can go up to 99.
+
+       2. If the CSV has separate amount fields for debit & credit (in & out):
+
+           a. If both fields are unsigned:
+           Assign to amountN-in and amountN-out.  This sets posting N's amount
+           to  whichever of these has a non-zero value, and negates the "-out"
+           value.
+
+           b. If either field is signed (can contain a minus sign):
+           Use a conditional rule to flip  the  sign  (of  non-empty  values).
+           Since  hledger  always negates amountN-out, if it was already nega-
+           tive, we must undo that by negating once  more  (but  only  if  the
+           field is non-empty):
+
+                  fields date, description, amount1-in, amount1-out
+                  if %amount1-out [1-9]
+                   amount1-out -%amount1-out
+
+           c. If both fields, or neither field, can contain a non-zero value:
+           hledger  normally  expects exactly one of the fields to have a non-
+           zero value.  Eg,  the  amountN-in/amountN-out  rules  would  reject
+           value pairs like these:
+
+                  "",  ""
+                  "0", "0"
+                  "1", "none"
+
+           So, use smarter conditional rules to set the amount from the appro-
+           priate field.  Eg, these rules would make it  use  only  the  value
+           containing non-zero digits, handling the above:
+
+                  fields date, description, in, out
+                  if %in [1-9]
+                   amount1 %in
+                  if %out [1-9]
+                   amount1 %out
+
+       3. If  you are stuck with hledger <1.17, or you want posting 2's amount
+          converted to cost:
+       Assign to amount (or to amount-in and amount-out).  (The old numberless
+       syntax, which sets amount1 and amount2.)
+
+       4. If the CSV has the balance instead of the transaction amount:
+       Assign to balanceN, which sets posting N's amount indirectly via a bal-
+       ance assignment.  (Old syntax: balance, equivalent to balance1.)
+
+           o If hledger guesses the wrong default account name:
+           When setting the amount via balance assertion,  hledger  may  guess
+           the  wrong  default account name.  So, set the account name explic-
+           itly, eg:
+
+                    fields date, description, balance1
+                    account1 assets:checking
+
+   Amount signs
+       There is some special handling for amount signs,  to  simplify  parsing
+       and sign-flipping:
+
+       o If an amount value begins with a plus sign:
+       that will be removed: +AMT becomes AMT
+
+       o If an amount value is parenthesised:
+       it will be de-parenthesised and sign-flipped: (AMT) becomes -AMT
+
+       o If  an  amount value has two minus signs (or two sets of parentheses,
+         or a minus sign and parentheses):
+       they cancel out and will be removed: --AMT or -(AMT) becomes AMT
+
+       o If an amount value contains just a sign (or just a set  of  parenthe-
+         ses):
+       that  is removed, making it an empty value.  "+" or "-" or "()" becomes
+       "".
+
+   Setting currency/commodity
+       If the currency/commodity  symbol  is  included  in  the  CSV's  amount
+       field(s):
+
+              2020-01-01,foo,$123.00
+
+       you don't have to do anything special for the commodity symbol, it will
+       be assigned as part of the amount.  Eg:
+
+              fields date,description,amount
+
+              2020-01-01 foo
+                  expenses:unknown         $123.00
+                  income:unknown          $-123.00
+
+       If the currency is provided as a separate CSV field:
+
+              2020-01-01,foo,USD,123.00
+
+       You can assign that to the currency pseudo-field, which has the special
+       effect  of prepending itself to every amount in the transaction (on the
+       left, with no separating space):
+
+              fields date,description,currency,amount
+
+              2020-01-01 foo
+                  expenses:unknown       USD123.00
+                  income:unknown        USD-123.00
+
+       Or, you can use a field assignment to construct  the  amount  yourself,
+       with more control.  Eg to put the symbol on the right, and separated by
+       a space:
+
+              fields date,description,cur,amt
+              amount %amt %cur
+
+              2020-01-01 foo
+                  expenses:unknown        123.00 USD
+                  income:unknown         -123.00 USD
+
+       Note we used a temporary field name (cur) that is not currency  -  that
+       would trigger the prepending effect, which we don't want here.
+
+   Amount decimal places
+       Like amounts in a journal file, the amounts generated by CSV rules like
+       amount1 influence commodity display styles, such as the number of deci-
+       mal places displayed in reports.
+
+       The  original  amounts as written in the CSV file do not affect display
+       style (because we don't yet reliably know their commodity).
+
+   Referencing other fields
+       In field assignments, you can interpolate only CSV fields, not  hledger
+       fields.   In  the example below, there's both a CSV field and a hledger
+       field named amount1, but %amount1 always means the CSV field,  not  the
+       hledger field:
+
+              # Name the third CSV field "amount1"
+              fields date,description,amount1
+
+              # Set hledger's amount1 to the CSV amount1 field followed by USD
+              amount1 %amount1 USD
+
+              # Set comment to the CSV amount1 (not the amount1 assigned above)
+              comment %amount1
+
+       Here,  since there's no CSV amount1 field, %amount1 will produce a lit-
+       eral "amount1":
+
+              fields date,description,csvamount
+              amount1 %csvamount USD
+              # Can't interpolate amount1 here
+              comment %amount1
+
+       When there are multiple field assignments to the  same  hledger  field,
+       only the last one takes effect.  Here, comment's value will be be B, or
+       C if "something" is matched, but never A:

+   How CSV rules are evaluated
+       Here's how to think of CSV rules being evaluated (if  you  really  need
+       to).  First,
+
+       o include  - all includes are inlined, from top to bottom, depth first.
+         (At each include point the file is inlined and  scanned  for  further
+         includes, recursively, before proceeding.)
+
+       Then  "global"  rules  are  evaluated,  top  to  bottom.   If a rule is
+       repeated, the last one wins:
+
+       o skip (at top level)
+
+       o date-format
+
+       o newest-first
+
+       o fields - names the CSV fields, optionally sets up initial assignments
+         to hledger fields
+
+       Then for each CSV record in turn:
+
+       o test  all  if  blocks.   If  any of them contain a end rule, skip all
+         remaining CSV records.  Otherwise if any of them contain a skip rule,
+         skip  that  many  CSV  records.   If  there are multiple matched skip
+         rules, the first one wins.
+
+       o collect all field assignments at top level and in matched if  blocks.
+         When  there  are multiple assignments for a field, keep only the last
+         one.
+
+       o compute a value for each hledger field -  either  the  one  that  was
+         assigned  to  it (and interpolate the %CSVFIELDNAME references), or a
+         default
+
+       o generate a synthetic hledger transaction from these values.
+
+       This is all part of the CSV reader, one of several readers hledger  can
+       use  to parse input files.  When all files have been read successfully,
+       the transactions are passed as input to whichever hledger  command  the
+       user specified.
+
+TIMECLOCK FORMAT
+       The time logging format of timeclock.el, as read by hledger.
+
+       hledger  can read time logs in timeclock format.  As with Ledger, these
+       are (a subset of) timeclock.el's format, containing clock-in and clock-
+       out  entries  as in the example below.  The date is a simple date.  The
+       time format is HH:MM[:SS][+-ZZZZ].  Seconds and timezone are  optional.
+       The timezone, if present, must be four digits and is ignored (currently
+       the time is always interpreted as a local time).
+
+              i 2015/03/30 09:00:00 some:account name  optional description after two spaces
+              o 2015/03/30 09:20:00
+              i 2015/03/31 22:21:45 another account
+              o 2015/04/01 02:00:34
+
+       hledger treats each clock-in/clock-out pair as  a  transaction  posting
+       some  number of hours to an account.  Or if the session spans more than
+       one day, it is split into several transactions, one for each day.   For
+       the above time log, hledger print generates these journal entries:
+
+              $ hledger -f t.timeclock print
+              2015-03-30 * optional description after two spaces
+                  (some:account name)         0.33h
+
+              2015-03-31 * 22:21-23:59
+                  (another account)         1.64h
+
+              2015-04-01 * 00:00-02:00
+                  (another account)         2.01h
+
+       Here is a sample.timeclock to download and some queries to try:
+
+              $ hledger -f sample.timeclock balance                               # current time balances
+              $ hledger -f sample.timeclock register -p 2009/3                    # sessions in march 2009
+              $ hledger -f sample.timeclock register -p weekly --depth 1 --empty  # time summary by week
+
+       To generate time logs, ie to clock in and clock out, you could:
+
+       o use  emacs  and the built-in timeclock.el, or the extended timeclock-
+         x.el and perhaps the extras in ledgerutils.el
+
+       o at the command line, use these bash aliases: shell     alias ti="echo
+         i  `date  '+%Y-%m-%d  %H:%M:%S'` \$* >>$TIMELOG"     alias to="echo o
+         `date '+%Y-%m-%d %H:%M:%S'` >>$TIMELOG"
+
+       o or use the old ti and to scripts in the ledger 2.x repository.  These
+         rely  on  a "timeclock" executable which I think is just the ledger 2
+         executable renamed.
+
+TIMEDOT FORMAT
+       timedot format is hledger's human-friendly time logging  format.   Com-
+       pared to timeclock format, it is
+
+       o convenient for quick, approximate, and retroactive time logging
+
+       o readable: you can see at a glance where time was spent.
+
+       A  timedot file contains a series of day entries, which might look like
+       this:
+
+              2021-08-04
+              hom:errands          .... ....
+              fos:hledger:timedot  ..         ; docs
+              per:admin:finance
+
+       hledger reads this as three time transactions on this  day,  with  each
+       dot representing a quarter-hour spent:
+
+              $ hledger -f a.timedot print   # .timedot file extension activates the timedot reader
+              2021-08-04 *
+                  (hom:errands)            2.00
+
+              2021-08-04 *
+                  (fos:hledger:timedot)    0.50
+
+              2021-08-04 *
+                  (per:admin:finance)      0
+
+       A day entry begins with a date line:
+
+       o a non-indented simple date (Y-M-D, Y/M/D, or Y.M.D).
+
+       Optionally this can be followed on the same line by
+
+       o a common transaction description for this day
+
+       o a common transaction comment for this day, after a semicolon (;).
+
+       After  the date line are zero or more optionally-indented time transac-
+       tion lines, consisting of:
+
+       o an account name - any word or phrase, usually a hledger-style account
+         name.
+
+       o two  or  more  spaces  -  a  field separator, required if there is an
+         amount (as in journal format).
+
+       o a timedot amount - dots representing quarter hours, or a number  rep-
+         resenting hours.
+
+       o an optional comment beginning with semicolon.  This is ignored.
+
+       In more detail, timedot amounts can be:
+
+       o dots:  zero or more period characters, each representing one quarter-
+         hour.  Spaces are ignored and can be used for grouping.  Eg: ....  ..
+
+       o a number, representing hours.  Eg: 1.5
+
+       o a  number immediately followed by a unit symbol s, m, h, d, w, mo, or
+         y, representing seconds, minutes, hours, days weeks, months or years.
+         Eg 1.5h or 90m.  The following equivalencies are assumed:
+       60s  =  1m,  60m  = 1h, 24h = 1d, 7d = 1w, 30d = 1mo, 365d = 1y.  (This
+       unit will not be visible in the generated transaction amount, which  is
+       always in hours.)
+
+       There  is  some added flexibility to help with keeping time log data in
+       the same file as your notes, todo lists, etc.:
+
+       o Lines beginning with # or ;, and blank lines, are ignored.
+
+       o Lines not ending with a double-space and amount are parsed as  trans-
+         actions  with  zero  amount.   (Most  hledger  reports  hide these by
+         default; add -E to see them.)
+
+       o One or more stars (*) followed by a space, at the start of a line, is
+         ignored.   So  date  lines or time transaction lines can also be Org-
+         mode headlines.
+
+       o All Org-mode headlines before the first date line are ignored.

+
+   Constructing command lines
+       hledger has an extensive  and  powerful  command  line  interface.   We
+       strive to keep it simple and ergonomic, but you may run into one of the
+       confusing real world details described in OPTIONS, below.  If that hap-
+       pens, here are some tips that may help:
+
+       o command-specific  options must go after the command (it's fine to put
+         all options there) (hledger CMD OPTS ARGS)
+
+       o running add-on executables directly simplifies command  line  parsing
+         (hledger-ui OPTS ARGS)
+
+       o enclose "problematic" args in single quotes
+
+       o if  needed, also add a backslash to hide regular expression metachar-
+         acters from the shell
+
+       o to see how a misbehaving command is being parsed, add --debug=2.
+
+   Starting a journal file
+       hledger  looks  for  your  accounting   data   in   a   journal   file,
+       $HOME/.hledger.journal by default:
+
+              $ hledger stats
+              The hledger journal file "/Users/simon/.hledger.journal" was not found.
+              Please create it first, eg with "hledger add" or a text editor.
+              Or, specify an existing journal file with -f or LEDGER_FILE.
+
+       You  can override this by setting the LEDGER_FILE environment variable.
+       It's a good practice to keep this important file under version control,
+       and  to  start  a  new  file each year.  So you could do something like
+       this:
+
+              $ mkdir ~/finance
+              $ cd ~/finance
+              $ git init
+              Initialized empty Git repository in /Users/simon/finance/.git/
+              $ touch 2020.journal
+              $ echo "export LEDGER_FILE=$HOME/finance/2020.journal" >> ~/.bashrc
+              $ source ~/.bashrc
+              $ hledger stats
+              Main file                : /Users/simon/finance/2020.journal
+              Included files           :
+              Transactions span        :  to  (0 days)
+              Last transaction         : none
+              Transactions             : 0 (0.0 per day)
+              Transactions last 30 days: 0 (0.0 per day)
+              Transactions last 7 days : 0 (0.0 per day)
+              Payees/descriptions      : 0
+              Accounts                 : 0 (depth 0)
+              Commodities              : 0 ()
+              Market prices            : 0 ()
+
+   Setting opening balances
+       Pick a starting date for which you can look up  the  balances  of  some
+       real-world  assets  (bank  accounts,  wallet..) and liabilities (credit
+       cards..).
+
+       To avoid a lot of data entry, you may want to start with  just  one  or
+       two  accounts,  like  your  checking account or cash wallet; and pick a
+       recent starting date, like today or the start of  the  week.   You  can
+       always come back later and add more accounts and older transactions, eg
+       going back to january 1st.
+
+       Add an opening balances transaction to the journal, declaring the  bal-
+       ances on this date.  Here are two ways to do it:
+
+       o The  first way: open the journal in any text editor and save an entry
+         like this:
+
+                2020-01-01 * opening balances
+                    assets:bank:checking                $1000   = $1000
+                    assets:bank:savings                 $2000   = $2000
+                    assets:cash                          $100   = $100
+                    liabilities:creditcard               $-50   = $-50
+                    equity:opening/closing balances
+
+         These are start-of-day balances, ie whatever was in  the  account  at
+         the end of the previous day.
+
+         The  *  after  the  date  is  an optional status flag.  Here it means
+         "cleared & confirmed".
+
+         The currency symbols are optional, but usually a good idea as  you'll
+         be dealing with multiple currencies sooner or later.
+
+         The  = amounts are optional balance assertions, providing extra error
+         checking.
+
+       o The second way: run hledger add and follow the prompts  to  record  a
+         similar transaction:
+
+                $ hledger add
+                Adding transactions to journal file /Users/simon/finance/2020.journal
+                Any command line arguments will be used as defaults.
+                Use tab key to complete, readline keys to edit, enter to accept defaults.
+                An optional (CODE) may follow transaction dates.
+                An optional ; COMMENT may follow descriptions or amounts.
+                If you make a mistake, enter < at any prompt to go one step backward.
+                To end a transaction, enter . when prompted.
+                To quit, enter . at a date prompt or press control-d or control-c.
+                Date [2020-02-07]: 2020-01-01
+                Description: * opening balances

+
+       If  you're  using  version control, this could be a good time to commit

+
+   Recording transactions
+       As you spend or receive money, you can record these transactions  using
+       one  of  the  methods  above (text editor, hledger add) or by using the
+       hledger-iadd or hledger-web add-ons, or by using the import command  to
+       convert CSV data downloaded from your bank.
+
+       Here  are  some  simple transactions, see the hledger_journal(5) manual
+       and hledger.org for more ideas:
+
+              2020/1/10 * gift received
+                assets:cash   $20
+                income:gifts
+
+              2020.1.12 * farmers market
+                expenses:food    $13
+                assets:cash
+
+              2020-01-15 paycheck
+                income:salary
+                assets:bank:checking    $1000
+
+   Reconciling
+       Periodically you should reconcile - compare your hledger-reported  bal-
+       ances  against  external sources of truth, like bank statements or your
+       bank's website - to be sure that your ledger accurately represents  the
+       real-world  balances  (and,  that  the real-world institutions have not
+       made a mistake!).  This gets easy and fast with (1)  practice  and  (2)
+       frequency.   If  you do it daily, it can take 2-10 minutes.  If you let
+       it pile up, expect it to take longer as you hunt down errors  and  dis-
+       crepancies.
+
+       A typical workflow:
+
+       1. Reconcile  cash.   Count  what's  in your wallet.  Compare with what
+          hledger reports (hledger bal cash).  If they are different,  try  to
+          remember  the  missing  transaction,  or  look  for the error in the
+          already-recorded transactions.  A register  report  can  be  helpful
+          (hledger  reg cash).  If you can't find the error, add an adjustment
+          transaction.  Eg if you have $105 after the above, and can't explain
+          the missing $2, it could be:
+
+                  2020-01-16 * adjust cash
+                      assets:cash    $-2 = $105
+                      expenses:misc
+
+       2. Reconcile checking.  Log in to your bank's website.  Compare today's
+          (cleared) balance with hledger's cleared balance (hledger bal check-
+          ing  -C).  If they are different, track down the error or record the
+          missing transaction(s) or add an adjustment transaction, similar  to
+          the above.  Unlike the cash case, you can usually compare the trans-
+          action history and running balance  from  your  bank  with  the  one
+          reported  by  hledger  reg  checking -C.  This will be easier if you
+          generally record transaction dates  quite  similar  to  your  bank's
+          clearing dates.
+
+       3. Repeat for other asset/liability accounts.
+
+       Tip:  instead  of  the  register command, use hledger-ui to see a live-
+       updating register while you edit the journal: hledger-ui --watch --reg-
+       ister checking -C
+
+       After  reconciling,  it  could  be  a  good time to mark the reconciled
+       transactions' status as "cleared and confirmed", if you want  to  track
+       that,  by  adding  the * marker.  Eg in the paycheck transaction above,
+       insert * between 2020-01-15 and paycheck
+
+       If you're using version control, this can be another good time to  com-
+       mit:
+
+              $ git commit -m 'txns' 2020.journal

+
+   Migrating to a new file
+       At the end of the year, you may want to continue your journal in a  new
+       file, so that old transactions don't slow down or clutter your reports,
+       and to help ensure the integrity of your accounting history.   See  the
+       close command.
+
+       If using version control, don't forget to git add the new file.
+
+LIMITATIONS
+       The  need  to  precede add-on command options with -- when invoked from
+       hledger is awkward.
+
+       When input data contains non-ascii characters, a suitable system locale
+       must be configured (or there will be an unhelpful error).  Eg on POSIX,
+       set LANG to something other than C.
+
+       In a Microsoft Windows CMD window, non-ascii characters and colours are
+       not supported.
+
+       On Windows, non-ascii characters may not display correctly when running
+       a hledger built in CMD in MSYS/CYGWIN, or vice-versa.
+
+       In a Cygwin/MSYS/Mintty window, the tab key is not supported in hledger
+       add.
+
+       Not  all of Ledger's journal file syntax is supported.  See file format
+       differences.
+
+       On large data files, hledger  is  slower  and  uses  more  memory  than
+       Ledger.
+
+TROUBLESHOOTING
+       Here  are  some  issues  you  might encounter when you run hledger (and
+       remember you can also seek help from the IRC channel, mail list or  bug
+       tracker):
+
+       Successfully installed, but "No command 'hledger' found"
+       stack and cabal install binaries into a special directory, which should
+       be added to your PATH environment variable.  Eg on  unix-like  systems,
+       that is ~/.local/bin and ~/.cabal/bin respectively.
+
+       I set a custom LEDGER_FILE, but hledger is still using the default file
+       LEDGER_FILE should be a real environment variable,  not  just  a  shell
+       variable.   The command env | grep LEDGER_FILE should show it.  You may
+       need to use export.  Here's an explanation.
+
+       Getting errors like "Illegal byte sequence" or "Invalid  or  incomplete
+       multibyte  or wide character" or "commitAndReleaseBuffer: invalid argu-
+       ment (invalid character)"
+       Programs compiled with GHC (hledger, haskell build tools, etc.) need to
+       have a UTF-8-aware locale configured in the environment, otherwise they
+       will fail with these kinds of  errors  when  they  encounter  non-ascii
+       characters.
+
+       To  fix it, set the LANG environment variable to some locale which sup-
+       ports UTF-8.  The locale you choose must be installed on your system.
+
+       Here's an example of setting LANG temporarily, on Ubuntu GNU/Linux:
+
+              $ file my.journal
+              my.journal: UTF-8 Unicode text         # the file is UTF8-encoded
+              $ echo $LANG
+              C                                      # LANG is set to the default locale, which does not support UTF8
+              $ locale -a                            # which locales are installed ?
+              C
+              en_US.utf8                             # here's a UTF8-aware one we can use
+              POSIX
+              $ LANG=en_US.utf8 hledger -f my.journal print   # ensure it is used for this command
+
+       If available, C.UTF-8 will also work.  If your preferred  locale  isn't
+       listed   by   locale   -a,  you  might  need  to  install  it.   Eg  on
+       Ubuntu/Debian:
+
+              $ apt-get install language-pack-fr
+              $ locale -a
+              C
+              en_US.utf8
+              fr_BE.utf8
+              fr_CA.utf8
+              fr_CH.utf8
+              fr_FR.utf8
+              fr_LU.utf8
+              POSIX
+              $ LANG=fr_FR.utf8 hledger -f my.journal print
+
+       Here's how you could set it permanently, if you use a bash shell:
+
+              $ echo "export LANG=en_US.utf8" >>~/.bash_profile
+              $ bash --login
+
+       Exact spelling and capitalisation may be important.  Note  the  differ-
+       ence  on  MacOS  (UTF-8,  not  utf8).  Some platforms (eg ubuntu) allow
+       variant spellings, but others (eg macos) require it to be exact:
+
+              $ locale -a | grep -iE en_us.*utf
+              en_US.UTF-8
+              $ LANG=en_US.UTF-8 hledger -f my.journal print

-     's', 'm', 'h', 'd', 'w', 'mo', or 'y', representing seconds,
-     minutes, hours, days weeks, months or years respectively.  Eg: 90m.
-     The following equivalencies are assumed, currently: 1m = 60s, 1h =
-     60m, 1d = 24h, 1w = 7d, 1mo = 30d, 1y=365d.
+   A day entry begins with a date line:
 
-   There is some flexibility allowing notes and todo lists to be kept
-right in the time log, if needed:
+   * a non-indented *simple date* (Y-M-D, Y/M/D, or Y.M.D).
 
-   * Blank lines and lines beginning with '#' or ';' are ignored.
+   Optionally this can be followed on the same line by
 
-   * Lines not ending with a double-space and quantity are parsed as
-     items taking no time, which will not appear in balance reports by
-     default.  (Add -E to see them.)
+   * a common *transaction description* for this day
+   * a common *transaction comment* for this day, after a semicolon
+     (';').
 
-   * Org mode headlines (lines beginning with one or more '*' followed
-     by a space) can be used as date lines or timelog items (the stars
-     are ignored).  Also all org headlines before the first date line
-     are ignored.  This means org users can manage their timelog as an
-     org outline (eg using org-mode/orgstruct-mode in Emacs), for
-     organisation, faster navigation, controlling visibility etc.
+   After the date line are zero or more optionally-indented time
+transaction lines, consisting of:
 
-   Examples:
+   * an *account name* - any word or phrase, usually a hledger-style
+     account name.
+   * *two or more spaces* - a field separator, required if there is an
+     amount (as in journal format).
+   * a *timedot amount* - dots representing quarter hours, or a number
+     representing hours.
+   * an optional *comment* beginning with semicolon.  This is ignored.
 
+   In more detail, timedot amounts can be:
+
+   * *dots*: zero or more period characters, each representing one
+     quarter-hour.  Spaces are ignored and can be used for grouping.
+     Eg: '.... ..'
+
+   * a *number*, representing hours.  Eg: '1.5'
+
+   * a *number immediately followed by a unit symbol* 's', 'm', 'h',
+     'd', 'w', 'mo', or 'y', representing seconds, minutes, hours, days
+     weeks, months or years.  Eg '1.5h' or '90m'.  The following
+     equivalencies are assumed:
+     '60s' = '1m', '60m' = '1h', '24h' = '1d', '7d' = '1w', '30d' =
+     '1mo', '365d' = '1y'.  (This unit will not be visible in the
+     generated transaction amount, which is always in hours.)
+
+   There is some added flexibility to help with keeping time log data in
+the same file as your notes, todo lists, etc.:
+
+   * Lines beginning with '#' or ';', and blank lines, are ignored.
+
+   * Lines not ending with a double-space and amount are parsed as
+     transactions with zero amount.  (Most hledger reports hide these by
+     default; add -E to see them.)
+
+   * One or more stars ('*') followed by a space, at the start of a
+     line, is ignored.  So date lines or time transaction lines can also
+     be Org-mode headlines.
+
+   * All Org-mode headlines before the first date line are ignored.

 NAME
        This  is  the  command-line  interface (CLI) for the hledger accounting
        tool.  Here we also describe hledger's concepts and file formats.  This
-       manual is for hledger 1.22.1.
-
-SYNOPSIS
-       hledger
-
-       hledger [-f FILE] COMMAND [OPTIONS] [ARGS]
-
-       hledger [-f FILE] ADDONCMD -- [OPTIONS] [ARGS]
-
-DESCRIPTION
-       hledger  is  a  reliable,  cross-platform  set of programs for tracking
-       money, time, or any other commodity, using double-entry accounting  and
-       a  simple,  editable  file  format.  hledger is inspired by and largely
-       compatible with ledger(1).
-
-       The basic function of the hledger CLI is to  read  a  plain  text  file
-       describing financial transactions (in accounting terms, a general jour-
-       nal) and print useful reports on standard output,  or  export  them  as
-       CSV.   hledger can also read some other file formats such as CSV files,
-       translating them to journal format.  Additionally, hledger lists  other
-       hledger-*  executables found in the user's $PATH and can invoke them as
-       subcommands.
-
-       hledger reads data from one or more files  in  hledger  journal,  time-
-       clock,  timedot,  or  CSV format specified with -f, or $LEDGER_FILE, or
-       $HOME/.hledger.journal          (on          windows,           perhaps
-       C:/Users/USER/.hledger.journal).  If using $LEDGER_FILE, note this must
-       be a real environment variable, not a shell variable.  You can  specify
-       standard input with -f-.
-
-       Transactions  are  dated movements of money between two (or more) named
-       accounts, and are recorded with journal entries like this:
-
-              2015/10/16 bought food
-               expenses:food          $10
-               assets:cash
-
-       Most users use a text editor to edit the journal, usually with an  edi-
-       tor mode such as ledger-mode for added convenience.  hledger's interac-
-       tive add command is another way to record  new  transactions.   hledger
-       never changes existing transactions.
-
-       To  get  started,  you  can  either save some entries like the above in
-       ~/.hledger.journal, or run hledger add and follow  the  prompts.   Then
-       try  some  commands like hledger print or hledger balance.  Run hledger
-       with no arguments for a list of commands.
-
-OPTIONS
-   General options
-       To see general usage help, including general  options  which  are  sup-
-       ported by most hledger commands, run hledger -h.

-       -C --cleared
-              include only cleared postings/txns
-
-       -R --real
-              include only non-virtual postings
-
-       -NUM --depth=NUM
-              hide/aggregate accounts or postings more than NUM levels deep
-
-       -E --empty
-              show  items with zero amount, normally hidden (and vice-versa in
-              hledger-ui/hledger-web)
-
-       -B --cost
-              convert amounts to their cost/selling amount at transaction time
-
-       -V --market
-              convert  amounts to their market value in default valuation com-
-              modities
-
-       -X --exchange=COMM
-              convert amounts to their market value in commodity COMM
-
-       --value
-              convert amounts to cost or  market  value,  more  flexibly  than
-              -B/-V/-X
-
-       --infer-market-prices
-              use  transaction  prices  (recorded  with @ or @@) as additional
-              market prices, as if they were P directives
-
-       --auto apply automated posting rules to modify transactions.
-
-       --forecast
-              generate future transactions from  periodic  transaction  rules,
-              for  the  next 6 months or till report end date.  In hledger-ui,
-              also make ordinary future transactions visible.
-
-       --color=WHEN (or --colour=WHEN)
-              Should color-supporting commands use ANSI color  codes  in  text
-              output.   'auto' (default): whenever stdout seems to be a color-
-              supporting terminal.  'always' or 'yes': always, useful eg  when
-              piping  output  into  'less  -R'.   'never'  or  'no': never.  A
-              NO_COLOR environment variable overrides this.
-
-       When a reporting option appears more than once in the command line, the
-       last one takes precedence.
-
-       Some reporting options can also be written as query arguments.
-
-   Command options
-       To  see  options  for  a particular command, including command-specific
-       options, run: hledger COMMAND -h.
-
-       Command-specific options must be written after the  command  name,  eg:
-       hledger print -x.
-
-       Additionally,  if  the  command  is  an add-on, you may need to put its
-       options after a double-hyphen, eg: hledger ui -- --watch.  Or, you  can
-       run the add-on executable directly: hledger-ui --watch.
-
-   Command arguments
-       Most  hledger  commands  accept arguments after the command name, which
-       are often a query, filtering the data in some way.
-
-       You can save a set of command line options/arguments  in  a  file,  and
-       then  reuse  them by writing @FILENAME as a command line argument.  Eg:
-       hledger bal @foo.args.  (To prevent this, eg if you  have  an  argument
-       that  begins  with  a literal @, precede it with --, eg: hledger bal --
-       @ARG).
-
-       Inside the argument file, each line should contain just one  option  or
-       argument.  Avoid the use of spaces, except inside quotes (or you'll see
-       a confusing error).  Between a flag and its argument, use =  (or  noth-
-       ing).  Bad:
-
-              assets depth:2
-              -X USD
-
-       Good:
-
-              assets
-              depth:2
-              -X=USD
-
-       For  special characters (see below), use one less level of quoting than
-       you would at the command prompt.  Bad:
-
-              -X"$"
-
-       Good:
-
-              -X$
-
-       See also: Save frequently used options.
-
-   Special characters
-   Single escaping (shell metacharacters)
-       In shell command lines, characters significant to your shell - such  as
-       spaces,  <, >, (, ), |, $ and \ - should be "shell-escaped" if you want
-       hledger to see them.  This is done by enclosing them in single or  dou-
-       ble  quotes,  or  by  writing  a backslash before them.  Eg to match an
-       account name containing a space:
-
-              $ hledger register 'credit card'
-
-       or:
-
-              $ hledger register credit\ card
-
-       Windows users should keep in mind that cmd treats  single  quote  as  a
-       regular  character,  so  you should be using double quotes exclusively.
-       PowerShell treats both single and double quotes as quotes.
-
-   Double escaping (regular expression metacharacters)
-       Characters significant in regular expressions (described below) -  such
-       as  .,  ^,  $, [, ], (, ), |, and \ - may need to be "regex-escaped" if
-       you don't want them to be interpreted by hledger's  regular  expression
-       engine.   This  is  done  by writing backslashes before them, but since
-       backslash is typically also a shell metacharacter, both  shell-escaping
-       and  regex-escaping will be needed.  Eg to match a literal $ sign while
-       using the bash shell:
-
-              $ hledger balance cur:'\$'
-
-       or:
-
-              $ hledger balance cur:\\$
-
-   Triple escaping (for add-on commands)
-       When you use hledger to  run  an  external  add-on  command  (described
-       below),  one  level of shell-escaping is lost from any options or argu-
-       ments intended for by the add-on command, so those need an extra  level
-       of  shell-escaping.   Eg to match a literal $ sign while using the bash
-       shell and running an add-on command (ui):
-
-              $ hledger ui cur:'\\$'
-
-       or:
-
-              $ hledger ui cur:\\\\$
-
-       If you wondered why four backslashes, perhaps this helps:
-
-
-       unescaped:        $
-       escaped:          \$
-       double-escaped:   \\$
-       triple-escaped:   \\\\$
-
-       Or, you can avoid the extra escaping by running the  add-on  executable
-       directly:
-
-              $ hledger-ui cur:\\$
-
-   Less escaping
-       Options and arguments are sometimes used in places other than the shell
-       command line, where shell-escaping is not needed, so there  you  should
-       use one less level of escaping.  Those places include:
-
-       o an @argumentfile
-
-       o hledger-ui's filter field
-
-       o hledger-web's search form
-
-       o GHCI's prompt (used by developers).
-
-   Unicode characters
-       hledger is expected to handle non-ascii characters correctly:
-
-       o they  should  be  parsed  correctly in input files and on the command
-         line, by all hledger tools (add, iadd, hledger-web's  search/add/edit
-         forms, etc.)
-
-       o they  should  be  displayed  correctly  by all hledger tools, and on-
-         screen alignment should be preserved.
-
-       This requires a well-configured environment.  Here are some tips:
-
-       o A system locale must be configured, and  it  must  be  one  that  can
-         decode the characters being used.  In bash, you can set a locale like
-         this: export LANG=en_US.UTF-8.  There are some more details in  Trou-
-         bleshooting.   This step is essential - without it, hledger will quit
-         on encountering a non-ascii character (as with all GHC-compiled  pro-
-         grams).
-
-       o your  terminal  software  (eg  Terminal.app, iTerm, CMD.exe, xterm..)
-         must support unicode
-
-       o the terminal must be using a font which includes the required unicode
-         glyphs
-
-       o the  terminal should be configured to display wide characters as dou-
-         ble width (for report alignment)
-
-       o on Windows, for best results you should run hledger in the same  kind
-         of  environment in which it was built.  Eg hledger built in the stan-
-         dard CMD.EXE environment (like the binaries  on  our  download  page)
-         might  show  display  problems when run in a cygwin or msys terminal,
-         and vice versa.  (See eg #961).
-
-   Regular expressions
-       hledger uses regular expressions in a number of places:
-
-       o query terms, on the command line and in the hledger-web search  form:
-         REGEX, desc:REGEX, cur:REGEX, tag:...=REGEX
-
-       o CSV rules conditional blocks: if REGEX ...
-
-       o account  alias  directives  and options: alias /REGEX/ = REPLACEMENT,
-         --alias /REGEX/=REPLACEMENT
-
-       hledger's regular expressions come from  the  regex-tdfa  library.   If
-       they're  not doing what you expect, it's important to know exactly what
-       they support:
-
-       1. they are case insensitive
-
-       2. they are infix matching (they do not need to match the entire  thing
-          being matched)
-
-       3. they are POSIX ERE (extended regular expressions)
-
-       4. they also support GNU word boundaries (\b, \B, \<, \>)
-
-       5. they  do  not support backreferences; if you write \1, it will match
-          the digit 1.  Except when doing  text  replacement,  eg  in  account
-          aliases,  where backreferences can be used in the replacement string
-          to reference capturing groups in the search regexp.
-
-       6. they do not support mode modifiers ((?s)),  character  classes  (\w,
-          \d), or anything else not mentioned above.
-
-       Some things to note:
-
-       o In  the  alias directive and --alias option, regular expressions must
-         be enclosed in forward  slashes  (/REGEX/).   Elsewhere  in  hledger,
-         these are not required.
-
-       o In  queries,  to match a regular expression metacharacter like $ as a
-         literal character, prepend a backslash.  Eg  to  search  for  amounts
-         with the dollar sign in hledger-web, write cur:\$.
-
-       o On  the command line, some metacharacters like $ have a special mean-
-         ing to the shell and so must be escaped at least once more.  See Spe-
-         cial characters.
-
-ENVIRONMENT
-       LEDGER_FILE The journal file path when not specified with -f.  Default:
-       ~/.hledger.journal (on  windows,  perhaps  C:/Users/USER/.hledger.jour-
-       nal).
-
-       A  typical  value  is  ~/DIR/YYYY.journal,  where DIR is a version-con-
-       trolled finance directory and YYYY is the current year.  Or  ~/DIR/cur-
-       rent.journal, where current.journal is a symbolic link to YYYY.journal.
-
-       On Mac computers, you can set this and other environment variables in a
-       more  thorough  way that also affects applications started from the GUI
-       (say,  an  Emacs  dock  icon).   Eg  on  MacOS  Catalina   I   have   a
-       ~/.MacOSX/environment.plist file containing
-
-              {
-                "LEDGER_FILE" : "~/finance/current.journal"
-              }
-
-       To see the effect you may need to killall Dock, or reboot.
-
-       COLUMNS  The  screen  width used by the register command.  Default: the
-       full terminal width.
-
-       NO_COLOR If this variable exists with any value, hledger will  not  use
-       ANSI   color   codes   in   terminal   output.    This   overrides  the
-       --color/--colour option.
-
-DATA FILES
-       hledger reads transactions from one or more data  files.   The  default
-       data  file  is  $HOME/.hledger.journal  (or  on Windows, something like
-       C:/Users/USER/.hledger.journal).
-
-       You can override this with the $LEDGER_FILE environment variable:
-
-              $ setenv LEDGER_FILE ~/finance/2016.journal
-              $ hledger stats
-
-       or with one or more -f/--file options:
-
-              $ hledger -f /some/file -f another_file stats
-
-       The file name - means standard input:
-
-              $ cat some.journal | hledger -f-
-
-   Data formats
-       Usually the data file is in hledger's journal format, but it can be  in
-       any of the supported file formats, which currently are:
-
-
-       Reader:    Reads:                                    Used  for  file  exten-
-                                                            sions:
-       -----------------------------------------------------------------------------
-       journal    hledger journal files and  some  Ledger   .journal   .j  .hledger
-                  journals, for transactions                .ledger
-       time-      timeclock  files, for precise time log-   .timeclock
-       clock      ging
-       timedot    timedot  files,  for  approximate  time   .timedot
-                  logging
-       csv        comma/semicolon/tab/other-separated       .csv .ssv .tsv
-                  values, for data import
-
-       These formats are described in their own sections, below.
-
-       hledger detects the format automatically based on the  file  extensions
-       shown  above.   If  it  can't  recognise the file extension, it assumes
-       journal format.  So for non-journal files,  it's  important  to  use  a
-       recognised file extension, so as to either read successfully or to show
-       relevant error messages.
-
-       You can also force a specific reader/format by prefixing the file  path
-       with the format and a colon.  Eg, to read a .dat file as csv format:
-
-              $ hledger -f csv:/some/csv-file.dat stats
-
-       Or to read stdin (-) as timeclock format:
-
-              $ echo 'i 2009/13/1 08:00:00' | hledger print -ftimeclock:-
-
-   Multiple files
-       You  can specify multiple -f options, to read multiple files as one big
-       journal.  There are some limitations with this:
-
-       o most directives do not affect sibling files
-
-       o balance assertions will not see any account  balances  from  previous
-         files
-
-       If you need either of those things, you can
-
-       o use a single parent file which includes the others
-
-       o or  concatenate  the files into one before reading, eg: cat a.journal
-         b.journal | hledger -f- CMD.
-
-   Strict mode
-       hledger checks input files for valid data.  By default, the most impor-
-       tant  errors  are  detected,  while  still accepting easy journal files
-       without a lot of declarations:
-
-       o Are the input files parseable, with valid syntax ?
-
-       o Are all transactions balanced ?
-
-       o Do all balance assertions pass ?
-
-       With the -s/--strict flag, additional checks are performed:
-
-       o Are all accounts posted to, declared  with  an  account  directive  ?
-         (Account error checking)
-
-       o Are all commodities declared with a commodity directive ?  (Commodity
-         error checking)
-
-       o Are all commodity conversions declared explicitly ?
-
-       You can also use the check command to run  these  and  some  additional
-       checks.
-
-TIME PERIODS
-   Smart dates
-       hledger's user interfaces accept a flexible "smart date" syntax.  Smart
-       dates allow some english words, can be relative to  today's  date,  and
-       can have less-significant date parts omitted (defaulting to 1).
-
-       Examples:
-
-
-       2004/10/1,   2004-01-01,   exact date, several separators allowed.   Year
-       2004.9.1                   is 4+ digits, month is 1-12, day is 1-31
-       2004                       start of year
-       2004/10                    start of month
-       10/1                       month and day in current year
-       21                         day in current month
-       october, oct               start of month in current year
-       yesterday, today, tomor-   -1, 0, 1 days from today
-       row
-       last/this/next             -1, 0, 1 periods from the current period
-       day/week/month/quar-
-       ter/year
-       20181201                   8 digit YYYYMMDD with valid year month and day
-       201812                     6 digit YYYYMM with valid year and month
-
-       Counterexamples  -  malformed  digit  sequences  might  give surprising
-       results:
-
-
-       201813        6 digits with an  invalid  month  is  parsed  as  start  of
-                     6-digit year
-       20181301      8  digits  with  an  invalid  month  is  parsed as start of
-                     8-digit year
-       20181232      8 digits with an invalid day gives an error
-       201801012     9+ digits beginning with a valid YYYYMMDD gives an error
-
-
-   Report start & end date
-       By default, most hledger reports will show the full span of time repre-
-       sented by the journal data.  The report start date will be the earliest
-       transaction or posting date, and the report end date will be the latest
-       transaction, posting, or market price date.
-
-       Often  you  will  want  to see a shorter time span, such as the current
-       month.  You can specify a  start  and/or  end  date  using  -b/--begin,
-       -e/--end, -p/--period or a date: query (described below).  All of these
-       accept the smart date syntax.
-
-       Some notes:
-
-       o As in Ledger, end dates are exclusive, so you need to write the  date
-         after the last day you want to include.
-
-       o As  noted  in reporting options: among start/end dates specified with
-         options, the last (i.e.  right-most) option takes precedence.
-
-       o The effective report start and end dates are the intersection of  the
-         start/end  dates  from options and that from date: queries.  That is,
-         date:2019-01 date:2019 -p'2000 to  2030'  yields  January  2019,  the
-         smallest common time span.
-
-       o A  report  interval  (see  below)  will  adjust start/end dates, when
-         needed, so that they fall on subperiod boundaries.
-
-       Examples:
-
-
-       -b 2016/3/17       begin on St. Patrick's day 2016
-       -e 12/1            end  at  the  start  of  december  1st of the current year
-                          (11/30 will be the last date included)
-       -b thismonth       all transactions on or after the 1st of the current month
-       -p thismonth       all transactions in the current month
-       date:2016/3/17..   the  above  written  as  queries  instead  (.. can also be
-                          replaced with -)
-       date:..12/1
-       date:thismonth..
-       date:thismonth
-
-   Report intervals
-       A report interval can be specified so that commands like register, bal-
-       ance and activity become multi-period, showing each subperiod as a sep-
-       arate row or column.
-
-       The following "standard" report intervals can be enabled by using their
-       corresponding flag:
-
-       -D/--daily, -W/--weekly, -M/--monthly, -Q/--quarterly, -Y/--yearly.
-
-       These standard intervals always start on natural  interval  boundaries:
-       eg  --weekly  starts  on  mondays, --monthly starts on the first of the
-       month, --yearly always starts on January 1st, etc.
-
-       Certain more complex intervals, and more flexible boundary  dates,  can
-       be  specified  by  -p/--period.   These are described in period expres-
-       sions, below.
-
-       Report intervals can only be specified by the flags above, and  not  by
-       query arguments, currently.
-
-       Report  intervals  have another effect: multi-period reports are always
-       expanded to fill a whole number of subperiods.  So if you use a  report
-       interval  (other  than  --daily), and you have specified a start or end
-       date, you may notice those  dates  being  overridden  (ie,  the  report
-       starts  earlier than your requested start date, or ends later than your
-       requested end date).  This is done to ensure "full" first and last sub-
-       periods, so that all subperiods' numbers are comparable.
-
-   Period expressions
-       The  -p/--period  option accepts period expressions, a shorthand way of
-       expressing a start date, end date, and/or report interval all at  once.
-
-       Here's  a basic period expression specifying the first quarter of 2009.
-       Note, hledger always treats start dates as inclusive and end  dates  as
-       exclusive:
-
-       -p "from 2009/1/1 to 2009/4/1"
-
-       Keywords  like  "from" and "to" are optional, and so are the spaces, as
-       long as you don't run two dates together.  "to" can also be written  as
-       ".." or "-".  These are equivalent to the above:
-
-
-       -p "2009/1/1 2009/4/1"
-       -p2009/1/1to2009/4/1
-       -p2009/1/1..2009/4/1
-
-       Dates  are  smart  dates, so if the current year is 2009, the above can
-       also be written as:
-
-
-       -p "1/1 4/1"
-
-       -p "january-apr"
-       -p "this year to 4/1"
-
-       If you specify only one date, the missing start or end date will be the
-       earliest or latest transaction in your journal:
-
-
-       -p "from 2009/1/1"   everything  after  january
-                            1, 2009
-       -p "from 2009/1"     the same
-       -p "from 2009"       the same
-       -p "to 2009"         everything before  january
-                            1, 2009
-
-       A  single  date  with  no "from" or "to" defines both the start and end
-       date like so:
-
-
-       -p "2009"       the year 2009;  equivalent
-                       to "2009/1/1 to 2010/1/1"
-       -p "2009/1"     the  month of jan; equiva-
-                       lent   to   "2009/1/1   to
-                       2009/2/1"
-       -p "2009/1/1"   just  that day; equivalent
-                       to "2009/1/1 to 2009/1/2"
-
-       Or you can specify a single quarter like so:
-
-
-       -p "2009Q1"   first  quarter  of   2009,
-                     equivalent to "2009/1/1 to
-                     2009/4/1"
-       -p "q4"       fourth quarter of the cur-
-                     rent year
-
-       The  argument  of  -p  can  also  begin  with, or be, a report interval
-       expression.  The basic report intervals  are  daily,  weekly,  monthly,
-       quarterly, or yearly, which have the same effect as the -D,-W,-M,-Q, or
-       -Y flags.  Between report interval and start/end dates  (if  any),  the
-       word in is optional.  Examples:
-
-
-       -p "weekly from 2009/1/1 to 2009/4/1"
-       -p "monthly in 2008"
-       -p "quarterly"
-
-       Note  that  weekly, monthly, quarterly and yearly intervals will always
-       start on the first day on week, month, quarter or year accordingly, and
-       will  end  on  the  last  day of same period, even if associated period
-       expression specifies different explicit start and end date.
-
-       For example:
-
-
-       -p "weekly from  2009/1/1   starts on 2008/12/29, closest preceding Mon-
-       to 2009/4/1"                day
-       -p      "monthly       in   starts on 2018/11/01
-       2008/11/25"
-       -p     "quarterly    from   starts  on  2009/04/01,  ends on 2009/06/30,
-       2009-05-05 to 2009-06-01"   which are first and last days of Q2 2009
-       -p      "yearly      from   starts on 2009/01/01, first day of 2009
-       2009-12-29"
-
-       The  following  more  complex  report  intervals  are  also  supported:
-       biweekly, fortnightly,  bimonthly,  every  day|week|month|quarter|year,
-       every N days|weeks|months|quarters|years.
-
-       All  of  these  will start on the first day of the requested period and
-       end on the last one, as described above.
-
-       Examples:
-
-
-       -p "bimonthly from 2008"    periods will have boundaries on  2008/01/01,
-                                   2008/03/01, ...
-       -p "every 2 weeks"          starts on closest preceding Monday
-       -p  "every  5  month from   periods will have boundaries on  2009/03/01,
-       2009/03"                    2009/08/01, ...
-
-       If  you want intervals that start on arbitrary day of your choosing and
-       span a week, month or year, you need to use any of the following:
-
-       every    Nth     day     of     week,     every     WEEKDAYNAME     (eg
-       mon|tue|wed|thu|fri|sat|sun), every Nth day [of month], every Nth WEEK-
-       DAYNAME [of month], every MM/DD [of year], every  Nth  MMM  [of  year],
-       every MMM Nth [of year].
-
-       Examples:
-
-
-       -p  "every  2nd  day  of   periods will go from Tue to Tue
-       week"
-       -p "every Tue"             same
-       -p "every 15th day"        period boundaries will  be  on  15th  of  each
-                                  month
-       -p "every 2nd Monday"      period  boundaries will be on second Monday of
-                                  each month
-       -p "every 11/05"           yearly periods with boundaries on 5th of Nov
-       -p "every 5th Nov"         same
-       -p "every Nov 5th"         same
-
-       Show historical balances at end of 15th each month (N is exclusive  end
-       date):
-
-       hledger balance -H -p "every 16th day"
-
-       Group  postings  from  start  of wednesday to end of next tuesday (N is
-       start date and exclusive end date):
-
-       hledger register checking -p "every 3rd day of week"
-
-DEPTH
-       With the --depth N option (short form: -N), commands like account, bal-
-       ance  and register will show only the uppermost accounts in the account
-       tree, down to level N.  Use this when you  want  a  summary  with  less
-       detail.   This  flag has the same effect as a depth: query argument (so
-       -2, --depth=2 or depth:2 are equivalent).
-
-QUERIES
-       One of hledger's strengths is being able to quickly report on a precise
-       subset of your data.  Most hledger commands accept optional query argu-
-       ments to restrict their scope.  The syntax is as follows:
-
-       o Zero or more space-separated  query  terms.   These  are  most  often
-         account name substrings:
-
-         utilities food:groceries
-
-       o Terms  with  spaces or other special characters should be enclosed in
-         quotes:
-
-         "personal care"
-
-       o Regular expressions are also supported:
-
-         "^expenses\b" "accounts (payable|receivable)"
-
-       o Add a query type prefix to match other parts of the data:
-
-         date:202012- desc:amazon cur:USD amt:">100" status:
-
-       o Add a not: prefix to negate a term:
-
-         not:cur:USD
-
-   Query types
-       Here are the types of query term available.  Remember these can also be
-       prefixed with not: to convert them into a negative match.
-
-       acct:REGEX, REGEX
-       Match  account names containing this (case insensitive) regular expres-
-       sion.  This is the default query type when there is no prefix, and reg-
-       ular  expression  syntax  is  typically  not needed, so usually we just
-       write an account name substring, like expenses or food.
-
-       amt:N, amt:<N, amt:<=N, amt:>N, amt:>=N
-       Match postings with a single-commodity amount equal to, less  than,  or
-       greater  than N.  (Postings with multi-commodity amounts are not tested
-       and will always match.) The comparison has two modes: if N is  preceded
-       by  a + or - sign (or is 0), the two signed numbers are compared.  Oth-
-       erwise, the absolute magnitudes are compared, ignoring sign.
-
-       code:REGEX
-       Match by transaction code (eg check number).
-
-       cur:REGEX
-       Match  postings  or  transactions  including  any  amounts  whose  cur-
-       rency/commodity  symbol  is  fully  matched  by  REGEX.  (For a partial
-       match, use .*REGEX.*).  Note, to match  special  characters  which  are
-       regex-significant,  you need to escape them with \.  And for characters
-       which are significant to your shell you may  need  one  more  level  of
-       escaping.  So eg to match the dollar sign:
-       hledger print cur:\\$.
-
-       desc:REGEX
-       Match transaction descriptions.
-
-       date:PERIODEXPR
-       Match  dates  (or  with  the  --date2 flag, secondary dates) within the
-       specified period.  PERIODEXPR is a period  expression  with  no  report
-       interval.  Examples:
-       date:2016, date:thismonth, date:2/1-2/15, date:2021-07-27..nextquarter.
-
-       date2:PERIODEXPR
-       Match secondary dates within the specified period (independent  of  the
-       --date2 flag).
-
-       depth:N
-       Match  (or  display,  depending  on  command) accounts at or above this
-       depth.
-
-       note:REGEX
-       Match transaction notes (the part of the description right of |, or the
-       whole description if there's no |).
-
-       payee:REGEX
-       Match  transaction  payee/payer names (the part of the description left
-       of |, or the whole description if there's no |).
-
-       real:, real:0
-       Match real or virtual postings respectively.
-
-       status:, status:!, status:*
-       Match unmarked, pending, or cleared transactions respectively.
-
-       tag:REGEX[=REGEX]
-       Match by tag name, and optionally also by tag value.  (To match only by
-       value,  use  tag:.=REGEX.)  Note  that  postings also inherit tags from
-       their transaction, and transactions also acquire tags from their  post-
-       ings, when querying.
-
-       (inacct:ACCTNAME
-       A  special  query  term  used  automatically in hledger-web only: tells
-       hledger-web to show the transaction register for an account.)
-
-   Combining query terms
-       Most commands select things which match:
-
-       o any of the description terms AND
-
-       o any of the account terms AND
-
-       o any of the status terms AND
-
-       o all the other terms.
-
-       while the print command shows transactions which:
-
-       o match any of the description terms AND
-
-       o have any postings matching any of the positive account terms AND
-
-       o have no postings matching any of the negative account terms AND
-
-       o match all the other terms.
-
-       You can do more powerful queries (such as AND-ing two  like  terms)  by
-       running  a  first query with print, and piping the result into a second
-       hledger command.  Eg: how much of food expenses was paid with cash ?
-
-              $ hledger print assets:cash | hledger f- -I balance expenses:food
-
-       If you are interested in full  boolean  expressions  for  queries,  see
-       #203.
-
-   Queries and command options
-       Some  queries can also be expressed as command-line options: depth:2 is
-       equivalent to --depth 2, date:2020 is equivalent to -p 2020, etc.  When
-       you  mix  command  options and query arguments, generally the resulting
-       query is their intersection.
-
-   Queries and account aliases
-       When account names are rewritten with  --alias  or  alias,  acct:  will
-       match either the old or the new account name.
-
-   Queries and valuation
-       When  amounts  are  converted  to  other  commodities  in cost or value
-       reports, cur: and amt: match the  old  commodity  symbol  and  the  old
-       amount  quantity, not the new ones (except in hledger 1.22.0 where it's
-       reversed, see #1625).
-
-   Querying with account aliases
-       When account names are rewritten with --alias or alias, note that acct:
-       will match either the old or the new account name.
-
-   Querying with cost or value
-       When  amounts  are  converted  to  other  commodities  in cost or value
-       reports, note that cur: matches the new commodity symbol, and  not  the
-       old one, and amt: matches the new quantity, and not the old one.  Note:
-       this changed in hledger 1.22, previously it was the  reverse,  see  the
-       discussion at #1625.
-
-COSTING
-       The  -B/--cost  flag  converts  amounts to their cost or sale amount at
-       transaction time, if they have a transaction price specified.  If  this
-       flag  is supplied, hledger will perform cost conversion first, and will
-       apply any market price valuations (if requested) afterwards.
-
-VALUATION
-       Instead of reporting amounts in their original commodity,  hledger  can
-       convert them to cost/sale amount (using the conversion rate recorded in
-       the transaction), and/or to market value (using some market price on  a
-       certain  date).   This  is  controlled  by the --value=TYPE[,COMMODITY]
-       option, which will be described below.  We also provide the simpler  -V
-       and -X COMMODITY options, and often one of these is all you need:
-
-   -V: Value
-       The  -V/--market flag converts amounts to market value in their default
-       valuation commodity, using the market prices in effect on the valuation
-       date(s), if any.  More on these in a minute.
-
-   -X: Value in specified commodity
-       The -X/--exchange=COMM option is like -V, except you tell it which cur-
-       rency you want to convert to, and it tries  to  convert  everything  to
-       that.
-
-   Valuation date
-       Since  market  prices  can change from day to day, market value reports
-       have a valuation date (or more than one), which determines which market
-       prices will be used.
-
-       For single period reports, if an explicit report end date is specified,
-       that will be used as the valuation date; otherwise the  valuation  date
-       is the journal's end date.
-
-       For  multiperiod  reports, each column/period is valued on the last day
-       of the period, by default.
-
-   Market prices
-       To convert a commodity A to its market value in  another  commodity  B,
-       hledger  looks  for a suitable market price (exchange rate) as follows,
-       in this order of preference :
-
-       1. A declared market price or inferred market price: A's latest  market
-          price in B on or before the valuation date as declared by a P direc-
-          tive, or (with the --infer-market-price flag) inferred from transac-
-          tion prices.
-
-       2. A reverse market price: the inverse of a declared or inferred market
-          price from B to A.
-
-       3. A forward chain of market prices: a synthetic price formed  by  com-
-          bining the shortest chain of "forward" (only 1 above) market prices,
-          leading from A to B.
-
-       4. Any chain of market prices: a chain of any market prices,  including
-          both  forward  and reverse prices (1 and 2 above), leading from A to
-          B.
-
-       There is a limit to the  length  of  these  price  chains;  if  hledger
-       reaches  that length without finding a complete chain or exhausting all
-       possibilities, it will give up (with a "gave  up"  message  visible  in
-       --debug=2 output).  That limit is currently 1000.
-
-       Amounts  for  which no suitable market price can be found, are not con-
-       verted.
-
-   --infer-market-price: market prices from transactions
-       Normally, market value in hledger is fully controlled by, and requires,
-       P directives in your journal.  Since adding and updating those can be a
-       chore, and since transactions usually take place  at  close  to  market
-       value, why not use the recorded transaction prices as additional market
-       prices (as Ledger does) ?  We could produce value reports without need-
-       ing P directives at all.
-
-       Adding the --infer-market-price flag to -V, -X or --value enables this.
-       So for example, hledger bs  -V  --infer-market-price  will  get  market
-       prices  both  from  P  directives  and from transactions.  (And if both
-       occur on the same day, the P directive takes precedence).
-
-       There is a downside: value reports can sometimes be affected in confus-
-       ing/undesired  ways  by  your journal entries.  If this happens to you,
-       read all of this Valuation section carefully, and try adding --debug or
-       --debug=2 to troubleshoot.
-
-       --infer-market-price can infer market prices from:
-
-       o multicommodity transactions with explicit prices (@/@@)
-
-       o multicommodity  transactions with implicit prices (no @, two commodi-
-         ties, unbalanced).  (With  these,  the  order  of  postings  matters.
-         hledger print -x can be useful for troubleshooting.)
-
-       o but  not,  currently, from "more correct" multicommodity transactions
-         (no @, multiple commodities, balanced).
-
-   Valuation commodity
-       When you specify a valuation commodity (-X COMM or --value TYPE,COMM):
-       hledger will convert all amounts to COMM, wherever it can find a  suit-
-       able market price (including by reversing or chaining prices).
-
-       When  you  leave  the  valuation  commodity  unspecified (-V or --value
-       TYPE):
-       For each commodity A, hledger picks a default  valuation  commodity  as
-       follows, in this order of preference:
-
-       1. The price commodity from the latest P-declared market price for A on
-          or before valuation date.
-
-       2. The price commodity from the latest P-declared market price for A on
-          any  date.   (Allows  conversion  to proceed when there are inferred
-          prices before the valuation date.)
-
-       3. If there are no P directives at all (any commodity or date) and  the
-          --infer-market-price flag is used: the price commodity from the lat-
-          est transaction-inferred price for A on or before valuation date.
-
-       This means:
-
-       o If you have P directives, they determine which  commodities  -V  will
-         convert, and to what.
-
-       o If  you  have no P directives, and use the --infer-market-price flag,
-         transaction prices determine it.
-
-       Amounts for which no valuation commodity can  be  found  are  not  con-
-       verted.
-
-   Simple valuation examples
-       Here are some quick examples of -V:
-
-              ; one euro is worth this many dollars from nov 1
-              P 2016/11/01 EUR $1.10
-
-              ; purchase some euros on nov 3
-              2016/11/3
-                  assets:euros        EUR100
-                  assets:checking
-
-              ; the euro is worth fewer dollars by dec 21
-              P 2016/12/21 EUR $1.03
-
-       How many euros do I have ?

-   --value: Flexible valuation
-       -V and -X are special cases of the more general --value option:
-
-               --value=TYPE[,COMM]  TYPE is then, end, now or YYYY-MM-DD.
-                                    COMM is an optional commodity symbol.
-                                    Shows amounts converted to:
-                                    - default valuation commodity (or COMM) using market prices at posting dates
-                                    - default valuation commodity (or COMM) using market prices at period end(s)
-                                    - default valuation commodity (or COMM) using current market prices
-                                    - default valuation commodity (or COMM) using market prices at some date
-
-       The TYPE part selects cost or value and valuation date:
-
-       --value=then
-              Convert amounts to their value in the default valuation  commod-
-              ity, using market prices on each posting's date.
-
-       --value=end
-              Convert  amounts to their value in the default valuation commod-
-              ity, using market prices on the last day of  the  report  period
-              (or  if  unspecified, the journal's end date); or in multiperiod
-              reports, market prices on the last day of each subperiod.
-
-       --value=now
-              Convert amounts to their value in the default valuation  commod-
-              ity  using  current  market  prices (as of when report is gener-
-              ated).
-
-       --value=YYYY-MM-DD
-              Convert amounts to their value in the default valuation  commod-
-              ity using market prices on this date.
-
-       To select a different valuation commodity, add the optional ,COMM part:
-       a comma, then the  target  commodity's  symbol.   Eg:  --value=now,EUR.
-       hledger will do its best to convert amounts to this commodity, deducing
-       market prices as described above.

-
-       You  may  need  to  explicitly  set  a  commodity's display style, when
-       reverse prices are used.  Eg this output might be surprising:
-
-              P 2000-01-01 A 2B
-
-              2000-01-01
-                a  1B
-                b
-
-              $ hledger print -x -X A
-              2000-01-01
-                  a               0
-                  b               0
-
-       Explanation: because there's no amount or commodity directive  specify-
-       ing  a display style for A, 0.5A gets the default style, which shows no
-       decimal digits.  Because the displayed amount looks like zero, the com-
-       modity  symbol  and minus sign are not displayed either.  Adding a com-
-       modity directive sets a more useful display style for A:
-
-              P 2000-01-01 A 2B
-              commodity 0.00A
-
-              2000-01-01
-                a  1B
-                b
-
-              $ hledger print -X A
-              2000-01-01
-                  a           0.50A
-                  b          -0.50A
-
-   Effect of valuation on reports
-       Here is a reference for how valuation is supposed to affect  each  part
-       of  hledger's  reports  (and  a  glossary).  (It's wide, you'll have to
-       scroll sideways.) It may be useful when troubleshooting.  If  you  find
-       problems,  please  report  them,  ideally  with a reproducible example.

-PIVOTING
-       Normally hledger sums amounts, and organizes them in a hierarchy, based
-       on account name.  The --pivot FIELD option causes it to sum  and  orga-
-       nize  hierarchy  based on the value of some other field instead.  FIELD
-       can be: code, description, payee, note, or the full name (case insensi-
-       tive) of any tag.  As with account names, values containing colon:sepa-
-       rated:parts will be displayed hierarchically in reports.
-
-       --pivot is a general option affecting all reports;  you  can  think  of
-       hledger transforming the journal before any other processing, replacing
-       every posting's account name with the value of the specified  field  on
-       that posting, inheriting it from the transaction or using a blank value
-       if it's not present.
-
-       An example:
-
-              2016/02/16 Member Fee Payment
-                  assets:bank account                    2 EUR
-                  income:member fees                    -2 EUR  ; member: John Doe
-
-       Normal balance report showing account names:
-
-              $ hledger balance
-                             2 EUR  assets:bank account
-                            -2 EUR  income:member fees
-              --------------------
-                                 0
-
-       Pivoted balance report, using member: tag values instead:
-
-              $ hledger balance --pivot member
-                             2 EUR
-                            -2 EUR  John Doe
-              --------------------
-                                 0
-
-       One way to show only amounts with  a  member:  value  (using  a  query,
-       described below):
-
-              $ hledger balance --pivot member tag:member=.
-                            -2 EUR  John Doe
-              --------------------
-                            -2 EUR
-
-       Another  way  (the  acct:  query  matches  against the pivoted "account
-       name"):
-
-              $ hledger balance --pivot member acct:.
-                            -2 EUR  John Doe
-              --------------------
-                            -2 EUR
-
-OUTPUT
-   Output destination
-       hledger commands send their output to the terminal by default.  You can
-       of course redirect this, eg into a file, using standard shell syntax:
-
-              $ hledger print > foo.txt
-
-       Some  commands (print, register, stats, the balance commands) also pro-
-       vide the -o/--output-file option, which does  the  same  thing  without
-       needing the shell.  Eg:
-
-              $ hledger print -o foo.txt
-              $ hledger print -o -        # write to stdout (the default)
-
-       hledger   can   optionally   produce  debug  output  (if  enabled  with
-       --debug=N); this goes to stderr, and is not  affected  by  -o/--output-
-       file.   If you need to capture it, use shell redirects, eg: hledger bal
-       --debug=3 >file 2>&1.
-
-   Output format
-       Some commands (print, register, the balance commands) offer a choice of
-       output format.  In addition to the usual plain text format (txt), there
-       are CSV (csv), HTML (html), JSON (json) and SQL (sql).   This  is  con-
-       trolled by the -O/--output-format option:
-
-              $ hledger print -O csv
-
-       or, by a file extension specified with -o/--output-file:
-
-              $ hledger balancesheet -o foo.html   # write HTML to foo.html
-
-       The -O option can be used to override the file extension if needed:
-
-              $ hledger balancesheet -o foo.txt -O html   # write HTML to foo.txt
-
-       Some notes about JSON output:
-
-       o This  feature  is  marked  experimental,  and  not yet much used; you
-         should expect our JSON to evolve.  Real-world feedback is welcome.
-
-       o Our JSON is rather large and verbose, as it is quite a faithful  rep-
-         resentation  of  hledger's  internal  data  types.  To understand the
-         JSON,  read  the  Haskell  type  definitions,  which  are  mostly  in
-         https://github.com/simonmichael/hledger/blob/master/hledger-
-         lib/Hledger/Data/Types.hs.
-
-       o hledger represents quantities as Decimal values  storing  up  to  255
-         significant  digits,  eg  for  repeating  decimals.  Such numbers can
-         arise in practice (from automatically-calculated transaction prices),
-         and  would break most JSON consumers.  So in JSON, we show quantities
-         as simple Numbers with at most 10 decimal places.  We don't limit the
-         number  of  integer  digits, but that part is under your control.  We
-         hope this approach will not cause problems in practice; if  you  find
-         otherwise, please let us know.  (Cf #1195)
-
-       Notes about SQL output:
-
-       o SQL  output is also marked experimental, and much like JSON could use
-         real-world feedback.
-
-       o SQL output is expected to work with sqlite, MySQL and PostgreSQL
-
-       o SQL output is structured with the expectations that  statements  will
-         be  executed  in the empty database.  If you already have tables cre-
-         ated via SQL output of hledger, you would  probably  want  to  either
-         clear tables of existing data (via delete or truncate SQL statements)
-         or drop tables completely as otherwise your postings will be duped.
-
-COMMANDS
-       hledger provides a number of commands for producing reports and  manag-
-       ing  your  data.   Run  hledger  with no arguments to list the commands
-       available, and hledger CMD to run a command.  CMD can be the full  com-
-       mand  name, or its standard abbreviation shown in the commands list, or

-
-       Add-on commands:
-
-       Programs or scripts named hledger-SOMETHING in  your  PATH  are  add-on
-       commands;  these  appear  in  the  commands list with a + mark.  Two of
-       these are maintained and released with hledger:
-
-       o ui - an efficient terminal interface (TUI) for hledger
-
-       o web - a simple web interface (WUI) for hledger
-
-       And these add-ons are maintained separately:
-
-       o iadd - a more interactive alternative for the add command
-
-       o interest -  generates  interest  transactions  according  to  various
-         schemes
-
-       o stockquotes  -  downloads  market  prices  for  your commodities from
-         AlphaVantage (experimental)
-
-       Next, the detailed command docs, in alphabetical order.
-
-   accounts
-       accounts
-       Show account names.
-
-       This command lists account names, either declared with  account  direc-
-       tives  (--declared),  posted  to (--used), or both (the default).  With
-       query arguments, only matched account names and  account  names  refer-
-       enced  by matched postings are shown.  It shows a flat list by default.
-       With --tree, it uses indentation to show  the  account  hierarchy.   In
-       flat  mode you can add --drop N to omit the first few account name com-
-       ponents.  Account names can be depth-clipped with depth:N or --depth  N
-       or -N.
-
-       Examples:
-
-              $ hledger accounts
-              assets:bank:checking
-              assets:bank:saving
-              assets:cash
-              expenses:food
-              expenses:supplies
-              income:gifts
-              income:salary
-              liabilities:debts
-
-   activity
-       activity
-       Show an ascii barchart of posting counts per interval.
-
-       The  activity  command  displays an ascii histogram showing transaction
-       counts by day, week, month or other reporting interval (by day  is  the
-       default).  With query arguments, it counts only matched transactions.
-
-       Examples:
-
-              $ hledger activity --quarterly
-              2008-01-01 **
-              2008-04-01 *******
-              2008-07-01
-              2008-10-01 **
-
-   add
-       add
-       Prompt  for  transactions  and  add them to the journal.  Any arguments
-       will be used as default inputs for the first N prompts.
-
-       Many hledger users edit their journals directly with a text editor,  or
-       generate  them from CSV.  For more interactive data entry, there is the
-       add command, which prompts interactively on the console for new  trans-
-       actions, and appends them to the journal file (if there are multiple -f
-       FILE options, the first file is used.) Existing  transactions  are  not
-       changed.   This  is the only hledger command that writes to the journal
-       file.
-
-       To use it, just run hledger add and follow the prompts.  You can add as
-       many  transactions as you like; when you are finished, enter . or press
-       control-d or control-c to exit.
-
-       Features:
-
-       o add tries to provide useful defaults,  using  the  most  similar  (by
-         description)  recent transaction (filtered by the query, if any) as a
-         template.
-
-       o You can also set the initial defaults with command line arguments.
-
-       o Readline-style edit keys can be used during data entry.
-
-       o The tab key will auto-complete whenever possible - accounts, descrip-
-         tions,  dates  (yesterday,  today,  tomorrow).   If the input area is
-         empty, it will insert the default value.
-
-       o If the journal defines a default commodity, it will be added  to  any
-         bare numbers entered.
-
-       o A parenthesised transaction code may be entered following a date.
-
-       o Comments and tags may be entered following a description or amount.
-
-       o If you make a mistake, enter < at any prompt to go one step backward.
-
-       o Input prompts are displayed in a different colour when  the  terminal
-         supports it.
-
-       Example (see the tutorial for a detailed explanation):
-
-              $ hledger add
-              Adding transactions to journal file /src/hledger/examples/sample.journal
-              Any command line arguments will be used as defaults.
-              Use tab key to complete, readline keys to edit, enter to accept defaults.
-              An optional (CODE) may follow transaction dates.
-              An optional ; COMMENT may follow descriptions or amounts.
-              If you make a mistake, enter < at any prompt to go one step backward.
-              To end a transaction, enter . when prompted.
-              To quit, enter . at a date prompt or press control-d or control-c.
-              Date [2015/05/22]:
-              Description: supermarket
-              Account 1: expenses:food
-              Amount  1: $10
-              Account 2: assets:checking
-              Amount  2 [$-10.0]:
-              Account 3 (or . or enter to finish this transaction): .
-              2015/05/22 supermarket
-                  expenses:food             $10
-                  assets:checking        $-10.0
-
-              Save this transaction to the journal ? [y]:
-              Saved.
-              Starting the next transaction (. or ctrl-D/ctrl-C to quit)
-              Date [2015/05/22]: <CTRL-D> $
-
-       On  Microsoft  Windows,  the add command makes sure that no part of the
-       file path ends with a period, as that would cause problems (#1056).
-
-   aregister
-       aregister, areg
-
-       Show the transactions and running historical  balance  in  an  account,
-       with each line item representing one transaction.
-
-       aregister shows the transactions affecting a particular account and its
-       subaccounts, with each line item representing a whole transaction -  as
-       in  bank statements, hledger-ui, hledger-web and other accounting apps.
-
-       Note this is unlike the register command, which shows individual  post-
-       ings and does not always show a single account or a historical balance.
-
-       A reminder, "historical" balances include any balance from transactions
-       before the report start date, so (if opening balances are recorded cor-
-       rectly) aregister will show the real-world balances of an  account,  as
-       you would see in a bank statement.
-
-       As  a  quick  rule  of  thumb, use aregister for reconciling real-world
-       asset/liability accounts  and  register  for  reviewing  detailed  rev-
-       enues/expenses.
-
-       aregister  shows  the  register  for  just  one account (and its subac-
-       counts).  This account must be specified as the  first  argument.   You
-       can  write  either the full account name, or a case-insensitive regular
-       expression which will select the alphabetically first matched  account.
-       (Eg  if  you have assets:aaa:checking and assets:bbb:checking accounts,
-       hledger areg checking would select assets:aaa:checking.)
-
-       Any additional arguments form a query which will  filter  the  transac-
-       tions shown.
-
-       Each aregister line item shows:
-
-       o the  transaction's date (or the relevant posting's date if different,
-         see below)
-
-       o the names of all the other account(s) involved  in  this  transaction
-         (probably abbreviated)
-
-       o the total change to this account's balance from this transaction
-
-       o the account's historical running balance after this transaction.
-
-       Transactions  making a net change of zero are not shown by default; add
-       the -E/--empty flag to show them.
-
-       aregister ignores a depth limit, so its final total will always match a
-       balance report with similar arguments.
-
-       This  command  also  supports  the output destination and output format
-       options The output formats supported are txt, csv, and json.
-
-   aregister and custom posting dates
-       Transactions whose date is outside  the  report  period  can  still  be
-       shown,  if  they have a posting to this account dated inside the report
-       period.  (And in this case it's the posting date that is  shown.)  This
-       ensures that aregister can show an accurate historical running balance,
-       matching the one shown by register -H with the same arguments.
-
-       To filter strictly by transaction date  instead,  add  the  --txn-dates
-       flag.   If  you  use  this  flag  and some of your postings have custom
-       dates, it's probably best to assume the running balance is wrong.
-
-       Examples:
-
-       Show all transactions and  historical  running  balance  in  the  first
-       account whose name contains "checking":
-
-              $ hledger areg checking
-
-       Show  transactions and historical running balance in all asset accounts
-       during july:
-
-              $ hledger areg assets date:jul
-
-   balance
-       balance, bal
-       Show accounts and their balances.
-
-       balance is one of hledger's oldest and  most  versatile  commands,  for
-       listing  account  balances,  balance changes, values, value changes and
-       more, during one time period or many.  Generally it shows a table, with
-       rows representing accounts, and columns representing periods.
-
-       Note  there  are some higher-level variants of the balance command with
-       convenient defaults, which can be simpler to  use:  balancesheet,  bal-
-       ancesheetequity, cashflow and incomestatement.  When you need more con-
-       trol, then use balance.
-
-   balance features
-       Here's a quick overview of the balance command's features, followed  by
-       more  detailed  descriptions and examples.  Many of these work with the
-       higher-level commands as well.
-
-       balance can show..
-
-       o accounts as a list (-l) or a tree (-t)
-
-       o optionally depth-limited (-[1-9])
-
-       o sorted by declaration order and name, or by amount
-
-       ..and their..
-
-       o balance changes (the default)
-
-       o or actual and planned balance changes (--budget)
-
-       o or value of balance changes (-V)
-
-       o or change of balance values (--valuechange)
-
-       ..in..
-
-       o one time period (the whole journal period by default)
-
-       o or multiple periods (-D, -W, -M, -Q, -Y, -p INTERVAL)
-
-       ..either..
-
-       o per period (the default)
-
-       o or accumulated since report start date (--cumulative)
-
-       o or accumulated since account creation (--historical/-H)
-
-       ..possibly converted to..
-
-       o cost (--value=cost[,COMM]/--cost/-B)
-
-       o or market value, as of transaction dates (--value=then[,COMM])
-
-       o or at period ends (--value=end[,COMM])
-
-       o or now (--value=now)
-
-       o or at some other date (--value=YYYY-MM-DD)
-
-       ..with..
-
-       o totals  (-T),  averages  (-A),  percentages   (-%),   inverted   sign
-         (--invert)
-
-       o rows and columns swapped (--transpose)
-
-       o another field used as account name (--pivot)
-
-       o custom-formatted line items (single-period reports only) (--format)
-
-       This command supports the output destination and output format options,
-       with output formats txt, csv, json, and  (multi-period  reports  only:)
-       html.   In txt output in a colour-supporting terminal, negative amounts
-       are shown in red.
-
-   Simple balance report
-       With no arguments, balance shows a  list  of  all  accounts  and  their
-       change  of  balance  - ie, the sum of posting amounts, both inflows and
-       outflows - during the entire period of  the  journal.   For  real-world
-       accounts,  this  should  also match their end balance at the end of the
-       journal period (more on this below).
-
-       Accounts are sorted by declaration order if any,  and  then  alphabeti-
-       cally by account name.  For instance, using examples/sample.journal:
-
-              $ hledger bal
-                                $1  assets:bank:saving

-       Accounts with a zero balance (and no non-zero subaccounts, in tree mode
-       - see below) are hidden  by  default.   Use  -E/--empty  to  show  them
-       (revealing assets:bank:checking here):
-
-              $ hledger -f examples/sample.journal  bal  -E
-                                 0  assets:bank:checking

-
-       The  total  of  the amounts displayed is shown as the last line, unless
-       -N/--no-total is used.
-
-   Filtered balance report
-       You can show fewer accounts,  a  different  time  period,  totals  from
-       cleared transactions only, etc.  by using query arguments or options to
-       limit the postings being matched.  Eg:
-
-              $ hledger bal --cleared assets date:200806
-                               $-2  assets:cash
-              --------------------
-                               $-2
-
-   List or tree mode
-       By default, or with -l/--flat, accounts are shown as a flat  list  with
-       their full names visible, as in the examples above.
-
-       With  -t/--tree,  the  account  hierarchy  is  shown, with subaccounts'
-       "leaf" names indented below their parent:
-
-              $ hledger balance
-                               $-1  assets
-                                $1    bank:saving

-
-       Notes:
-
-       o "Boring" accounts are combined with their subaccount for more compact
-         output,  unless  --no-elide is used.  Boring accounts have no balance
-         of their own and just one subaccount (eg assets:bank and  liabilities
-         above).
-
-       o All  balances  shown  are "inclusive", ie including the balances from
-         all subaccounts.  Note this means  some  repetition  in  the  output,
-         which requires explanation when sharing reports with non-plaintextac-
-         counting-users.  A tree mode report's final total is the sum  of  the
-         top-level balances shown, not of all the balances shown.
-
-       o Each  group of sibling accounts (ie, under a common parent) is sorted
-         separately.
-
-   Depth limiting
-       With a depth:N query, or --depth N option, or just -N, balance  reports
-       will  show accounts only to the specified depth, hiding the deeper sub-
-       accounts.  Account balances at the depth limit always include the  bal-
-       ances  from  any  hidden  subaccounts (even in list mode).  This can be
-       useful for getting an overview.  Eg, limiting to depth 1:
-
-              $ hledger balance -N -1
-                               $-1  assets
-                                $2  expenses
-                               $-2  income
-                                $1  liabilities
-
-       You can also hide top-level account name parts, using --drop  N.   This
-       can be useful for hiding repetitive top-level account names:
-
-              $ hledger bal expenses --drop 1
-                                $1  food
-                                $1  supplies
-              --------------------
-                                $2
-
-
-   Multi-period balance report
-       With   a   report   interval   (set  by  the  -D/--daily,  -W/--weekly,
-       -M/--monthly, -Q/--quarterly, -Y/--yearly, or -p/--period  flag),  bal-
-       ance  shows a tabular report, with columns representing successive time
-       periods (and a title):
-
-              $ hledger balance --quarterly income expenses -E
-              Balance changes in 2008:
-
-                                 ||  2008q1  2008q2  2008q3  2008q4
-              ===================++=================================
-               expenses:food     ||       0      $1       0       0
-               expenses:supplies ||       0      $1       0       0
-               income:gifts      ||       0     $-1       0       0
-               income:salary     ||     $-1       0       0       0
-              -------------------++---------------------------------
-                                 ||     $-1      $1       0       0
-
-       Notes:
-
-       o The report's start/end dates will be expanded, if necessary, to fully
-         encompass the displayed subperiods (so that the first and last subpe-
-         riods have the same duration as the others).
-
-       o Leading and trailing periods (columns) containing all zeroes are  not
-         shown, unless -E/--empty is used.
-
-       o Accounts   (rows)   containing  all  zeroes  are  not  shown,  unless
-         -E/--empty is used.
-
-       o Amounts with many commodities are shown in abbreviated  form,  unless
-         --no-elide is used.  (experimental)
-
-       o Average  and/or  total columns can be added with the -A/--average and
-         -T/--row-total flags.
-
-       o The --transpose flag can be used to exchange rows and columns.
-
-       o The --pivot FIELD option causes a different transaction field  to  be
-         used as "account name".  See PIVOTING.
-
-       Multi-period reports with many periods can be too wide for easy viewing
-       in the terminal.  Here are some ways to handle that:
-
-       o Hide the totals row with -N/--no-total
-
-       o Convert to a single currency with -V
-
-       o Maximize the terminal window
-
-       o Reduce the terminal's font size
-
-       o View with a pager like less, eg: hledger bal -D  --color=yes  |  less
-         -RS
-
-       o Output  as  CSV and use a CSV viewer like visidata (hledger bal -D -O
-         csv | vd -f csv), Emacs' csv-mode  (M-x  csv-mode,  C-c  C-a),  or  a
-         spreadsheet (hledger bal -D -o a.csv && open a.csv)
-
-       o Output  as  HTML and view with a browser: hledger bal -D -o a.html &&
-         open a.html
-
-   Sorting by amount
-       With -S/--sort-amount, accounts with the largest (most  positive)  bal-
-       ances  are  shown first.  Eg: hledger bal expenses -MAS shows your big-
-       gest averaged monthly expenses first.
-
-       Revenues and liability balances are typically negative, however, so  -S
-       shows  these  in  reverse  order.   To  work  around  this, you can add
-       --invert to flip the signs.  (Or, use one of the higher-level  reports,
-       which  flip the sign automatically.  Eg: hledger incomestatement -MAS).
-
-
-   Percentages
-       With -%/--percent, balance reports show each account's value  expressed
-       as a percentage of the (column) total:
-
-              $ hledger bal expenses -Q -%
-              Balance changes in 2008:
-
-                                 || 2008Q1   2008Q2  2008Q3  2008Q4
-              ===================++=================================
-               expenses:food     ||      0   50.0 %       0       0
-               expenses:supplies ||      0   50.0 %       0       0
-              -------------------++---------------------------------
-                                 ||      0  100.0 %       0       0
-
-       Note it is not useful to calculate percentages if the amounts in a col-
-       umn have mixed signs.  In this case, make a separate  report  for  each
-       sign, eg:
-
-              $ hledger bal -% amt:`>0`
-              $ hledger bal -% amt:`<0`
-
-       Similarly,  if  the amounts in a column have mixed commodities, convert
-       them to one commodity with -B, -V, -X or --value, or  make  a  separate
-       report for each commodity:
-
-              $ hledger bal -% cur:\\$
-              $ hledger bal -% cur:EUR
-
-   Balance change, end balance
-       It's  important to be clear on the meaning of the numbers shown in bal-
-       ance reports.  Here is some terminology we use:
-
-       A balance change is the net  amount  added  to,  or  removed  from,  an
-       account during some period.
-
-       An  end balance is the amount accumulated in an account as of some date
-       (and some time, but hledger doesn't store that; assume end  of  day  in
-       your timezone).  It is the sum of previous balance changes.
-
-       We  call it a historical end balance if it includes all balance changes
-       since the account was created.  For a real world account, this means it
-       will  match  the  "historical record", eg the balances reported in your
-       bank statements or bank web UI.  (If they are correct!)
-
-       In general, balance changes are what you want  to  see  when  reviewing
-       revenues and expenses, and historical end balances are what you want to
-       see when reviewing or reconciling asset, liability and equity accounts.
-
-       balance  shows  balance changes by default.  To see accurate historical
-       end balances:
-
-       1. Initialise account starting  balances  with  an  "opening  balances"
-          transaction  (a  transfer  from  equity  to the account), unless the
-          journal covers the account's full lifetime.
-
-       2. Include all of of the account's prior postings in the report, by not
-          specifying  a  report  start  date,  or by using the -H/--historical
-          flag.  (-H causes report start date to be ignored when summing post-
-          ings.)
-
-   Balance report types
-       For more flexible reporting, there are three important option groups:
-
-       hledger  balance  [CALCULATIONTYPE]  [ACCUMULATIONTYPE] [VALUATIONTYPE]
-       ...
-
-       The first two are the most  important:  calculation  type  selects  the
-       basic  calculation  to  perform for each table cell, while accumulation
-       type says which postings should be included in each cell's calculation.
-       Typically  one  or  both of these are selected by default, so you don't
-       need to write them explicitly.  A valuation type can be  added  if  you
-       want to convert the basic report to value or cost.
-
-       Calculation type:
-       The basic calculation to perform for each table cell.  It is one of:
-
-       o --sum : sum the posting amounts (default)
-
-       o --budget : like --sum but also show a goal amount
-
-       o --valuechange : show the change in period-end historical balance val-
-         ues
-
-       Accumulation type:
-       Which postings should be included in each cell's  calculation.   It  is
-       one of:
-
-       o --change  :  postings  from column start to column end, ie within the
-         cell's period.  Typically used to  see  revenues/expenses.   (default
-         for balance, incomestatement)
-
-       o --cumulative  :  postings from report start to column end, eg to show
-         changes accumulated since the report's start date.  Rarely used.
-
-       o --historical/-H : postings from journal start to column end,  ie  all
-         postings from account creation to the end of the cell's period.  Typ-
-         ically  used  to  see  historical  end  balances  of  assets/liabili-
-         ties/equity.   (default  for  balancesheet, balancesheetequity, cash-
-         flow)
-
-       Valuation type:
-       Which kind of valuation, valuation date(s) and optionally a target val-
-       uation commodity to use.  It is one of:
-
-       o no valuation, show amounts in their original commodities (default)
-
-       o --value=cost[,COMM] : no valuation, show amounts converted to cost
-
-       o --value=then[,COMM] : show value at transaction dates
-
-       o --value=end[,COMM]  :  show value at period end date(s) (default with
-         --valuechange)
-
-       o --value=now[,COMM] : show value at today's date
-
-       o --value=YYYY-MM-DD[,COMM] : show value at another date
-
-       or one of their aliases: --cost/-B, --market/-V or --exchange/-X.
-
-       Most combinations of these options should produce  reasonable  reports,
-       but  if  you  find any that seem wrong or misleading, let us know.  The
-       following restrictions are applied:
-
-       o --valuechange implies --value=end
-
-       o --valuechange makes --change the default  when  used  with  the  bal-
-         ancesheet/balancesheetequity commands
-
-       o --cumulative or --historical disables --row-total/-T
-
-       For reference, here is what the combinations of accumulation and valua-
-       tion show:
-
-
-       Valua-     no valuation       --value= then       --value= end       --value= YYYY-
-       tion:                                                                MM-DD /now

-
-   Useful balance reports
-       Some frequently used balance options/reports are:
-
-       o bal -M revenues expenses
-       Show revenues/expenses in each month.  Also available as  the  incomes-
-       tatement command.
-
-       o bal -M -H assets liabilities
-       Show  historical  asset/liability  balances  at  each  month end.  Also
-       available as the balancesheet command.
-
-       o bal -M -H assets liabilities equity
-       Show historical asset/liability/equity  balances  at  each  month  end.
-       Also available as the balancesheetequity command.
-
-       o bal -M assets not:receivable
-       Show  changes  to  liquid  assets in each month.  Also available as the
-       cashflow command.
-
-       Also:
-
-       o bal -M expenses -2 -SA
-       Show monthly expenses summarised to  depth  2  and  sorted  by  average
-       amount.
-
-       o bal -M --budget expenses
-       Show monthly expenses and budget goals.
-
-       o bal -M --valuechange investments
-       Show monthly change in market value of investment assets.
-
-       o bal  investments  --valuechange  -D  date:lastweek  amt:'>1000'  -STA
-         [--invert]
-       Show top gainers [or losers] last week
-
-   Budget report
-       The --budget report type activates extra  columns  showing  any  budget
-       goals  for  each  account  and period.  The budget goals are defined by
-       periodic transactions.  This is very useful for comparing  planned  and
-       actual income, expenses, time usage, etc.
-
-       For  example,  you  can  take  average  monthly  expenses in the common
-       expense categories to construct a minimal monthly budget:
-
-              ;; Budget
-              ~ monthly
-                income  $2000
-                expenses:food    $400
-                expenses:bus     $50
-                expenses:movies  $30
-                assets:bank:checking
-
-              ;; Two months worth of expenses
-              2017-11-01
-                income  $1950
-                expenses:food    $396
-                expenses:bus     $49

-       This is different from a normal balance report in several ways:
-
-       o Only accounts with budget goals during the report period  are  shown,
-         by default.
-
-       o In  each  column,  in square brackets after the actual amount, budget
-         goal amounts are shown, and the actual/goal percentage.  (Note:  bud-
-         get goals should be in the same commodity as the actual amount.)
-
-       o All  parent accounts are always shown, even in list mode.  Eg assets,
-         assets:bank, and expenses above.
-
-       o Amounts always include all subaccounts, budgeted or unbudgeted,  even
-         in list mode.
-
-       This means that the numbers displayed will not always add up! Eg above,
-       the expenses actual amount includes the  gifts  and  supplies  transac-
-       tions,  but  the  expenses:gifts and expenses:supplies accounts are not
-       shown, as they have no budget amounts declared.
-
-       This can be confusing.  When you need to make things clearer,  use  the
-       -E/--empty  flag,  which  will reveal all accounts including unbudgeted
-       ones, giving the full picture.  Eg:
-
-              $ hledger balance -M --budget --empty

-   Budget report start date
-       This might be a bug, but for now: when making budget  reports,  it's  a
-       good idea to explicitly set the report's start date to the first day of
-       a reporting period, because a periodic rule like  ~  monthly  generates
-       its  transactions  on the 1st of each month, and if your journal has no
-       regular transactions on the 1st, the default report  start  date  could
-       exclude  that  budget  goal, which can be a little surprising.  Eg here
-       the default report period is just the day of 2020-01-15:
-
-              ~ monthly in 2020
-                (expenses:food)  $500
-
-              2020-01-15
-                expenses:food    $400
-                assets:checking
-
-              $ hledger bal expenses --budget

-
-       To avoid this, specify the budget report's  period,  or  at  least  the
-       start  date, with -b/-e/-p/date:, to ensure it includes the budget goal
-       transactions (periodic transactions) that  you  want.   Eg,  adding  -b
-       2020/1/1 to the above:
-
-              $ hledger bal expenses --budget -b 2020/1/1

-   Nested budgets
-       You  can  add budgets to any account in your account hierarchy.  If you
-       have budgets on both parent account and some of its children, then bud-
-       get(s)  of  the  child account(s) would be added to the budget of their
-       parent, much like account balances behave.
-
-       In the most simple case this means that once you add a  budget  to  any
-       account, all its parents would have budget as well.
-
-       To illustrate this, consider the following budget:
-
-              ~ monthly from 2019/01
-                  expenses:personal             $1,000.00
-                  expenses:personal:electronics    $100.00
-                  liabilities
-
-       With  this,  monthly  budget  for electronics is defined to be $100 and
-       budget for personal expenses is an additional $1000,  which  implicitly
-       means that budget for both expenses:personal and expenses is $1100.
-
-       Transactions  in  expenses:personal:electronics  will  be  counted both
-       towards its $100 budget and $1100 of expenses:personal ,  and  transac-
-       tions  in  any  other  subaccount of expenses:personal would be counted
-       towards only towards the budget of expenses:personal.
-
-       For example, let's consider these transactions:
-
-              ~ monthly from 2019/01
-                  expenses:personal             $1,000.00
-                  expenses:personal:electronics    $100.00
-                  liabilities
-
-              2019/01/01 Google home hub
-                  expenses:personal:electronics          $90.00
-                  liabilities                           $-90.00
-
-              2019/01/02 Phone screen protector
-                  expenses:personal:electronics:upgrades          $10.00
-                  liabilities
-
-              2019/01/02 Weekly train ticket
-                  expenses:personal:train tickets       $153.00
-                  liabilities
-
-              2019/01/03 Flowers
-                  expenses:personal          $30.00
-                  liabilities
-
-       As you can see, we  have  transactions  in  expenses:personal:electron-
-       ics:upgrades  and  expenses:personal:train  tickets,  and since both of
-       these accounts are without explicitly defined  budget,  these  transac-
-       tions would be counted towards budgets of expenses:personal:electronics
-       and expenses:personal accordingly:

-              $ hledger balance --budget -M

-   Customising single-period balance reports
-       For single-period balance reports displayed in the terminal (only), you
-       can use --format FMT to customise the format and content of each  line.
-       Eg:
-
-              $ hledger balance --format "%20(account) %12(total)"
-                            assets          $-1

-                              cash          $-2
-                          expenses           $2
-                              food           $1
-                          supplies           $1

-       The FMT format string (plus a newline) specifies the formatting applied
-       to each account/balance pair.  It may contain any suitable  text,  with
-       data fields interpolated like so:
-
-       %[MIN][.MAX](FIELDNAME)
-
-       o MIN pads with spaces to at least this width (optional)
-
-       o MAX truncates at this width (optional)
-
-       o FIELDNAME must be enclosed in parentheses, and can be one of:
-
-         o depth_spacer  - a number of spaces equal to the account's depth, or
-           if MIN is specified, MIN * depth spaces.
-
-         o account - the account's name
-
-         o total - the account's balance/posted total, right justified
-
-       Also, FMT can begin with an optional prefix to control  how  multi-com-
-       modity amounts are rendered:
-
-       o %_ - render on multiple lines, bottom-aligned (the default)
-
-       o %^ - render on multiple lines, top-aligned
-
-       o %, - render on one line, comma-separated
-
-       There  are  some  quirks.   Eg in one-line mode, %(depth_spacer) has no
-       effect, instead %(account) has indentation built  in.   Experimentation
-       may be needed to get pleasing results.
-
-       Some example formats:
-
-       o %(total) - the account's total
-
-       o %-20.20(account)  -  the account's name, left justified, padded to 20
-         characters and clipped at 20 characters
-
-       o %,%-50(account)  %25(total) - account name padded to  50  characters,
-         total  padded to 20 characters, with multiple commodities rendered on
-         one line
-
-       o %20(total)  %2(depth_spacer)%-(account) - the default format for  the
-         single-column balance report
-
-   balancesheet
-       balancesheet, bs
-       This  command  displays a balance sheet, showing historical ending bal-
-       ances of asset and liability accounts.  (To see equity as well, use the
-       balancesheetequity  command.)  Amounts  are  shown with normal positive
-       sign, as in conventional financial statements.
-
-       The asset and liability accounts shown are those accounts declared with
-       the  Asset or Cash or Liability type, or otherwise all accounts under a
-       top-level  asset  or  liability  account  (case  insensitive,   plurals

-       normal positive sign, as in conventional financial statements.
-
-       The  asset,  liability  and  equity  accounts  shown are those accounts
-       declared with the Asset, Cash, Liability or Equity type,  or  otherwise
-       all accounts under a top-level asset, liability or equity account (case

-
-   check
-       check
-       Check for various kinds of errors in your data.
-
-       hledger provides a number of built-in  error  checks  to  help  prevent
-       problems  in  your  data.  Some of these are run automatically; or, you
-       can use this check command to run them on demand, with no output and  a
-       zero  exit  code  if all is well.  Specify their names (or a prefix) as
-       argument(s).
-
-       Some examples:
-
-              hledger check      # basic checks
-              hledger check -s   # basic + strict checks
-              hledger check ordereddates payees  # basic + two other checks
-
-       Here are the checks currently available:
-
-   Basic checks
-       These checks are always run automatically, by (almost) all hledger com-
-       mands, including check:
-
-       o parseable - data files are well-formed and can be successfully parsed
-
-       o balancedwithautoconversion - all transactions are balanced, inferring
-         missing  amounts where necessary, and possibly converting commodities
-         using transaction prices or automatically-inferred transaction prices
-
-       o assertions  -  all  balance  assertions  in  the journal are passing.
-         (This check can be disabled with -I/--ignore-assertions.)
-
-   Strict checks
-       These additional checks are run when the -s/--strict (strict mode) flag
-       is  used.   Or,  they  can be run by giving their names as arguments to
-       check:
-
-       o accounts - all account names used by transactions have been declared
-
-       o commodities - all commodity symbols used have been declared
-
-       o balancednoautoconversion - transactions are balanced, possibly  using
-         explicit transaction prices but not inferred ones
-
-   Other checks
-       These  checks  can  be  run  only by giving their names as arguments to
-       check.  They are more  specialised  and  not  desirable  for  everyone,
-       therefore optional:
-
-       o ordereddates - transactions are ordered by date within each file
-
-       o payees - all payees used by transactions have been declared
-
-       o uniqueleafnames - all account leaf names are unique
-
-   Custom checks
-       A  few  more  checks  are are available as separate add-on commands, in
-       https://github.com/simonmichael/hledger/tree/master/bin:
-
-       o hledger-check-tagfiles - all  tag  values  containing  /  (a  forward
-         slash) exist as file paths
-
-       o hledger-check-fancyassertions  -  more complex balance assertions are
-         passing
-
-       You could make similar scripts to perform your own custom checks.  See:
-       Cookbook -> Scripting.
-
-   close
-       close, equity
-       Prints  a  "closing  balances"  transaction  and  an "opening balances"
-       transaction that bring account balances to and from zero, respectively.
-       These can be added to your journal file(s), eg to bring asset/liability
-       balances forward into  a  new  journal  file,  or  to  close  out  rev-
-       enues/expenses to retained earnings at the end of a period.
-
-       You  can  print  just one of these transactions by using the --close or
-       --open flag.  You can customise their descriptions  with  the  --close-
-       desc and --open-desc options.
-
-       One amountless posting to "equity:opening/closing balances" is added to
-       balance the transactions, by default.  You can customise  this  account
-       name  with  --close-acct  and  --open-acct;  if you specify only one of
-       these, it will be used for both.
-
-       With --x/--explicit, the equity posting's amount will be shown.  And if
-       it  involves multiple commodities, a posting for each commodity will be
-       shown, as with the print command.
-
-       With --interleaved, the equity postings are shown next to the  postings
-       they balance, which makes troubleshooting easier.
-
-       By default, transaction prices in the journal are ignored when generat-
-       ing the closing/opening transactions.   With  --show-costs,  this  cost
-       information  is  preserved  (balance -B reports will be unchanged after
-       the transition).  Separate postings are generated for each cost in each
-       commodity.   Note  this can generate very large journal entries, if you
-       have many foreign currency or investment transactions.
-
-   close usage
-       If you split your journal files by time (eg yearly), you will typically
-       run  this command at the end of the year, and save the closing transac-
-       tion as last entry of the old file, and the opening transaction as  the
-       first  entry  of the new file.  This makes the files self contained, so
-       that correct balances are reported no matter which of them are  loaded.
-       Ie,  if you load just one file, the balances are initialised correctly;
-       or if you load several files, the  redundant  closing/opening  transac-
-       tions  cancel  each other out.  (They will show up in print or register
-       reports; you can  exclude  them  with  a  query  like  not:desc:'(open-
-       ing|closing) balances'.)
-
-       If you're running a business, you might also use this command to "close
-       the books" at the end of  an  accounting  period,  transferring  income
-       statement  account  balances  to  retained  earnings.  (You may want to
-       change the equity account name to something like "equity:retained earn-
-       ings".)
-
-       By  default,  the  closing transaction is dated yesterday, the balances
-       are calculated as of end of yesterday, and the opening  transaction  is
-       dated  today.  To close on some other date, use: hledger close -e OPEN-
-       INGDATE.  Eg, to close/open on the 2018/2019  boundary,  use  -e  2019.
-       You can also use -p or date:PERIOD (any starting date is ignored).
-
-       Both   transactions   will   include   balance   assertions   for   the
-       closed/reopened accounts.  You probably shouldn't use status  or  real-
-       ness  filters (like -C or -R or status:) with this command, or the gen-
-       erated balance assertions will depend on these flags.  Likewise, if you
-       run  this  command  with  --auto,  the balance assertions will probably
-       always require --auto.
-
-       Examples:
-
-       Carrying asset/liability balances into a new file for 2019:
-
-              $ hledger close -f 2018.journal -e 2019 assets liabilities --open
-                  # (copy/paste the output to the start of your 2019 journal file)
-              $ hledger close -f 2018.journal -e 2019 assets liabilities --close
-                  # (copy/paste the output to the end of your 2018 journal file)
-
-       Now:
-
-              $ hledger bs -f 2019.journal                   # one file - balances are correct
-              $ hledger bs -f 2018.journal -f 2019.journal   # two files - balances still correct
-              $ hledger bs -f 2018.journal not:desc:closing  # to see year-end balances, must exclude closing txn
-
-       Transactions spanning the closing date can complicate matters, breaking
-       balance assertions:
-
-              2018/12/30 a purchase made in 2018, clearing the following year
-                  expenses:food          5
-                  assets:bank:checking  -5  ; [2019/1/2]
-
-       Here's one way to resolve that:
-
-              ; in 2018.journal:
-              2018/12/30 a purchase made in 2018, clearing the following year
-                  expenses:food          5
-                  liabilities:pending
-
-              ; in 2019.journal:
-              2019/1/2 clearance of last year's pending transactions
-                  liabilities:pending    5 = 0
-                  assets:checking
-
-   codes
-       codes
-       List the codes seen in transactions, in the order parsed.
-
-       This  command prints the value of each transaction's code field, in the
-       order transactions were parsed.  The transaction code  is  an  optional
-       value  written  in  parentheses between the date and description, often
-       used to store a cheque number, order number or similar.
-
-       Transactions aren't required to have a code, and missing or empty codes
-       will  not  be shown by default.  With the -E/--empty flag, they will be
-       printed as blank lines.
-
-       You can add a query to select a subset of transactions.
-
-       Examples:
-
-              1/1 (123)
-               (a)  1
-
-              1/1 ()
-               (a)  1
-
-              1/1
-               (a)  1
-
-              1/1 (126)
-               (a)  1
-
-              $ hledger codes
-              123
-              124
-              126
-
-              $ hledger codes -E
-              123
-              124
-
-
-              126
-
-   commodities
-       commodities
-       List all commodity/currency symbols used or declared in the journal.
-
-   descriptions
-       descriptions
-       List the unique descriptions that appear in transactions.
-
-       This command lists the unique descriptions that appear in transactions,
-       in  alphabetic order.  You can add a query to select a subset of trans-
-       actions.
-
-       Example:
-
-              $ hledger descriptions
-              Store Name
-              Gas Station | Petrol
-              Person A
-
-   diff
-       diff
-       Compares a particular account's transactions in two  input  files.   It
-       shows any transactions to this account which are in one file but not in
-       the other.
-
-       More precisely, for each posting affecting this account in either file,
-       it  looks for a corresponding posting in the other file which posts the
-       same amount to the same  account  (ignoring  date,  description,  etc.)
-       Since postings not transactions are compared, this also works when mul-
-       tiple bank transactions have been combined into a single journal entry.
-
-       This is useful eg if you have downloaded an account's transactions from
-       your bank (eg as CSV data).  When hledger and your bank disagree  about
-       the account balance, you can compare the bank data with your journal to
-       find out the cause.
-
-       Examples:
-
-              $ hledger diff -f $LEDGER_FILE -f bank.csv assets:bank:giro
-              These transactions are in the first file only:
-
-              2014/01/01 Opening Balances
-                  assets:bank:giro              EUR ...
-                  ...
-                  equity:opening balances       EUR -...
-
-              These transactions are in the second file only:
-
-   files
-       files
-       List all files included in the journal.  With a  REGEX  argument,  only
-       file  names matching the regular expression (case sensitive) are shown.
-
-   help
-       help
-       Show the hledger user manual in  one  of  several  formats,  optionally
-       positioned  at  a  given TOPIC (if possible).  TOPIC is any heading, or
-       heading prefix, in the manual.  Some examples: commands,  print,  'auto
-       postings', periodic.
-
-       This  command  shows  the user manual built in to this hledger version.
-       It can be useful if the correct version of the hledger manual,  or  the
-       usual viewing tools, are not installed on your system.
-
-       By default it uses the best viewer it can find in $PATH, in this order:
-       info, man, $PAGER (unless a topic is specified), less, or stdout.  When
-       run non-interactively, it always uses stdout.  Or you can select a par-
-       ticular viewer with the -i (info), -m (man), or -p (pager) flags.
-
-   import
-       import
-       Read new transactions added to each FILE since last run, and  add  them
-       to  the  main journal file.  Or with --dry-run, just print the transac-
-       tions that would be added.  Or with --catchup, just  mark  all  of  the
-       FILEs' transactions as imported, without actually importing any.
-
-       Unlike  other hledger commands, with import the journal file is an out-
-       put file, and will be modified, though only by appending (existing data
-       will  not  be changed).  The input files are specified as arguments, so
-       to import one or more CSV files to your  main  journal,  you  will  run
-       hledger import bank.csv or perhaps hledger import *.csv.
-
-       Note you can import from any file format, though CSV files are the most
-       common import source, and these docs focus on that case.
-
-   Deduplication
-       As a convenience import does deduplication while reading  transactions.
-       This does not mean "ignore transactions that look the same", but rather
-       "ignore transactions that have been seen before".  This is intended for
-       when  you  are  periodically  importing  foreign data which may contain
-       already-imported transactions.  So eg, if every day you  download  bank
-       CSV  files containing redundant data, you can safely run hledger import
-       bank.csv and only new transactions will be imported.  (import is  idem-
-       potent.)
-
-       Since  the  items  being  read (CSV records, eg) often do not come with
-       unique identifiers, hledger detects new transactions by date,  assuming
-       that:
-
-       1. new items always have the newest dates
-
-       2. item dates do not change across reads
-
-       3. and  items  with  the  same  date  remain in the same relative order
-          across reads.
-
-       These are often true of CSV files representing  transactions,  or  true
-       enough  so  that it works pretty well in practice.  1 is important, but
-       violations of 2 and 3 amongst the old transactions won't matter (and if
-       you  import  often, the new transactions will be few, so less likely to
-       be the ones affected).
-
-       hledger remembers the latest date processed in each input file by  sav-
-       ing a hidden ".latest" state file in the same directory.  Eg when read-
-       ing finance/bank.csv, it will look for  and  update  the  finance/.lat-
-       est.bank.csv  state file.  The format is simple: one or more lines con-
-       taining the same ISO-format date (YYYY-MM-DD),  meaning  "I  have  pro-
-       cessed  transactions  up  to  this  date, and this many of them on that
-       date." Normally you won't see or manipulate these state files yourself.
-       But  if  needed,  you  can  delete  them to reset the state (making all
-       transactions "new"), or you can construct them to "catch up" to a  cer-
-       tain date.
-
-       Note  deduplication  (and  updating of state files) can also be done by
-       print --new, but this is less often used.
-
-   Import testing
-       With --dry-run, the transactions that will be imported are  printed  to
-       the terminal, without updating your journal or state files.  The output
-       is valid journal format, like the print command, so  you  can  re-parse
-       it.   Eg,  to  see any importable transactions which CSV rules have not
-       categorised:
-
-              $ hledger import --dry bank.csv | hledger -f- -I print unknown
-
-       or (live updating):
-
-              $ ls bank.csv* | entr bash -c 'echo ====; hledger import --dry bank.csv | hledger -f- -I print unknown'
-
-   Importing balance assignments
-       Entries added by import will have their posting amounts  made  explicit
-       (like  hledger  print  -x).  This means that any balance assignments in
-       imported files must be evaluated; but, imported files don't get to  see
-       the  main file's account balances.  As a result, importing entries with
-       balance assignments (eg from an institution that provides only balances
-       and  not  posting  amounts)  will  probably  generate incorrect posting
-       amounts.  To avoid this problem, use print instead of import:
-
-              $ hledger print IMPORTFILE [--new] >> $LEDGER_FILE
-
-       (If you think import should leave amounts  implicit  like  print  does,
-       please test it and send a pull request.)
-
-   Commodity display styles
-       Imported amounts will be formatted according to the canonical commodity
-       styles (declared or inferred) in the main journal file.
-
-   incomestatement
-       incomestatement, is
-
-       This  command  displays  an  income  statement,  showing  revenues  and
-       expenses  during  one  or  more periods.  Amounts are shown with normal
-       positive sign, as in conventional financial statements.
-
-       The revenue and expense accounts shown are those accounts declared with
-       the  Revenue  or  Expense  type, or otherwise all accounts under a top-
-       level revenue or income or expense account (case  insensitive,  plurals
-       allowed).
-
-       Example:
-
-              $ hledger incomestatement
-              Income Statement
-
-              Revenues:
-                               $-2  income
-                               $-1    gifts
-                               $-1    salary
-              --------------------
-                               $-2
-
-              Expenses:
-                                $2  expenses
-                                $1    food
-                                $1    supplies
-              --------------------
-                                $2
-
-              Total:
-              --------------------
-                                 0
-
-       This command is a higher-level variant of the balance command, and sup-
-       ports many of that command's features, such  as  multi-period  reports.
-       It is similar to hledger balance '(revenues|income)' expenses, but with
-       smarter account detection, and  revenues/income  displayed  with  their
-       sign flipped.
-
-       This  command  also  supports  the output destination and output format
-       options The output formats supported are txt, csv, html,  and  (experi-
-       mental) json.
-
-   notes
-       notes
-       List the unique notes that appear in transactions.
-
-       This  command  lists  the  unique notes that appear in transactions, in
-       alphabetic order.  You can add a query to select a subset  of  transac-
-       tions.   The  note is the part of the transaction description after a |
-       character (or if there is no |, the whole description).
-
-       Example:
-
-              $ hledger notes
-              Petrol
-              Snacks
-
-   payees
-       payees
-       List the unique payee/payer names that appear in transactions.
-
-       This command lists unique payee/payer names which  have  been  declared
-       with  payee  directives  (--declared), used in transaction descriptions
-       (--used), or both (the default).
-
-       The payee/payer is the part of the transaction description before  a  |
-       character (or if there is no |, the whole description).
-
-       You  can  add query arguments to select a subset of transactions.  This
-       implies --used.
-
-       Example:
-
-              $ hledger payees
-              Store Name
-              Gas Station
-              Person A
-
-   prices
-       prices
-       Print market price directives from the  journal.   With  --costs,  also
-       print  synthetic  market  prices  based  on  transaction  prices.  With
-       --inverted-costs,  also  print  inverse  prices  based  on  transaction
-       prices.   Prices  (and  postings providing prices) can be filtered by a
-       query.  Price amounts are always displayed with their full precision.
-
-   print
-       print
-       Show transaction journal entries, sorted by date.
-
-       The print command displays full journal entries (transactions) from the
-       journal file, sorted by date (or with --date2, by secondary date).
-
-       Amounts  are shown mostly normalised to commodity display style, eg the
-       placement of commodity symbols will be consistent.  All of their  deci-
-       mal places are shown, as in the original journal entry (with one alter-
-       ation: in some cases trailing zeroes are added.)
-
-       Amounts are shown right-aligned within each transaction (but not across
-       all transactions).
-
-       Directives  and  inter-transaction  comments  are not shown, currently.
-       This means the print command is somewhat lossy, and if you are using it
-       to  reformat  your  journal  you should take care to also copy over the
-       directives and file-level comments.
-
-       Eg:
-
-              $ hledger print
-              2008/01/01 income
-                  assets:bank:checking            $1
-                  income:salary                  $-1
-
-              2008/06/01 gift
-                  assets:bank:checking            $1
-                  income:gifts                   $-1
-
-              2008/06/02 save
-                  assets:bank:saving              $1
-                  assets:bank:checking           $-1
-
-              2008/06/03 * eat & shop
-                  expenses:food                $1
-                  expenses:supplies            $1
-                  assets:cash                 $-2
-
-              2008/12/31 * pay off
-                  liabilities:debts               $1
-                  assets:bank:checking           $-1
-
-       print's output is usually a valid hledger journal, and you can  process
-       it again with a second hledger command.  This can be useful for certain
-       kinds of search, eg:
-
-              # Show running total of food expenses paid from cash.
-              # -f- reads from stdin. -I/--ignore-assertions is sometimes needed.
-              $ hledger print assets:cash | hledger -f- -I reg expenses:food
-
-       There are some situations where print's output can become unparseable:
-
-       o Valuation affects posting amounts but not balance assertion  or  bal-
-         ance assignment amounts, potentially causing those to fail.
-
-       o Auto postings can generate postings with too many missing amounts.
-
-       Normally, the journal entry's explicit or implicit amount style is pre-
-       served.  For example, when an amount is omitted in the journal, it will
-       not  appear  in  the  output.   Similarly,  when a transaction price is
-       implied but not written, it will not appear in the output.  You can use
-       the  -x/--explicit  flag  to  make  all  amounts and transaction prices
-       explicit, which can be useful for troubleshooting or  for  making  your
-       journal more readable and robust against data entry errors.  -x is also
-       implied by using any of -B,-V,-X,--value.
-
-       Note, -x/--explicit will cause postings with a  multi-commodity  amount
-       (these  can  arise  when  a multi-commodity transaction has an implicit
-       amount) to be split into multiple  single-commodity  postings,  keeping
-       the output parseable.
-
-       With  -B/--cost,  amounts with transaction prices are converted to cost
-       using that price.  This can be used for troubleshooting.
-
-       With -m/--match and a STR argument, print will show at most one  trans-
-       action:  the  one  one whose description is most similar to STR, and is
-       most recent.  STR should contain at least two characters.  If there  is
-       no similar-enough match, no transaction will be shown.
-
-       With  --new, hledger prints only transactions it has not seen on a pre-
-       vious run.  This uses the same deduplication system as the import  com-
-       mand.  (See import's docs for details.)
-
-       This  command  also  supports  the output destination and output format
-       options The output formats supported are txt, csv,  and  (experimental)
-       json and sql.
-
-       Here's an example of print's CSV output:
-
-              $ hledger print -Ocsv
-              "txnidx","date","date2","status","code","description","comment","account","amount","commodity","credit","debit","posting-status","posting-comment"
-              "1","2008/01/01","","","","income","","assets:bank:checking","1","$","","1","",""
-              "1","2008/01/01","","","","income","","income:salary","-1","$","1","","",""
-              "2","2008/06/01","","","","gift","","assets:bank:checking","1","$","","1","",""
-              "2","2008/06/01","","","","gift","","income:gifts","-1","$","1","","",""
-              "3","2008/06/02","","","","save","","assets:bank:saving","1","$","","1","",""
-              "3","2008/06/02","","","","save","","assets:bank:checking","-1","$","1","","",""
-              "4","2008/06/03","","*","","eat & shop","","expenses:food","1","$","","1","",""
-              "4","2008/06/03","","*","","eat & shop","","expenses:supplies","1","$","","1","",""
-              "4","2008/06/03","","*","","eat & shop","","assets:cash","-2","$","2","","",""
-              "5","2008/12/31","","*","","pay off","","liabilities:debts","1","$","","1","",""
-              "5","2008/12/31","","*","","pay off","","assets:bank:checking","-1","$","1","","",""
-
-       o There  is  one  CSV record per posting, with the parent transaction's
-         fields repeated.
-
-       o The "txnidx" (transaction index) field shows which postings belong to
-         the  same transaction.  (This number might change if transactions are
-         reordered within the file, files are parsed/included in  a  different
-         order, etc.)
-
-       o The  amount  is  separated into "commodity" (the symbol) and "amount"
-         (numeric quantity) fields.
-
-       o The numeric amount is repeated in either the "credit" or "debit" col-
-         umn,  for convenience.  (Those names are not accurate in the account-
-         ing sense; it just puts negative amounts under  credit  and  zero  or
-         greater amounts under debit.)
-
-   print-unique
-       print-unique
-       Print transactions which do not reuse an already-seen description.
-
-       Example:
-
-              $ cat unique.journal
-              1/1 test
-               (acct:one)  1
-              2/2 test
-               (acct:two)  2
-              $ LEDGER_FILE=unique.journal hledger print-unique
-              (-f option not supported)
-              2015/01/01 test
-                  (acct:one)             1
-
-   register
-       register, reg
-       Show postings and their running total.
-
-       The register command displays matched postings, across all accounts, in
-       date order, with their running total  or  running  historical  balance.
-       (See  also the aregister command, which shows matched transactions in a
-       specific account.)
-
-       register normally shows line per posting, but note that multi-commodity
-       amounts will occupy multiple lines (one line per commodity).
-
-       It  is  typically  used with a query selecting a particular account, to
-       see that account's activity:
-
-              $ hledger register checking
-              2008/01/01 income               assets:bank:checking            $1           $1
-              2008/06/01 gift                 assets:bank:checking            $1           $2
-              2008/06/02 save                 assets:bank:checking           $-1           $1
-              2008/12/31 pay off              assets:bank:checking           $-1            0
-
-       With --date2, it shows and sorts by secondary date instead.
-
-       The --historical/-H flag adds the balance from  any  undisplayed  prior
-       postings  to  the  running  total.  This is useful when you want to see
-       only recent activity, with a historically accurate running balance:
-
-              $ hledger register checking -b 2008/6 --historical
-              2008/06/01 gift                 assets:bank:checking            $1           $2
-              2008/06/02 save                 assets:bank:checking           $-1           $1
-              2008/12/31 pay off              assets:bank:checking           $-1            0
-
-       The --depth option limits the amount of sub-account detail displayed.
-
-       The --average/-A flag shows the running average posting amount  instead
-       of the running total (so, the final number displayed is the average for
-       the whole report period).  This flag implies --empty (see  below).   It
-       is  affected  by  --historical.   It  works  best when showing just one
-       account and one commodity.
-
-       The --related/-r flag shows the other postings in the  transactions  of
-       the postings which would normally be shown.
-
-       The  --invert flag negates all amounts.  For example, it can be used on
-       an income account where amounts are normally displayed as negative num-
-       bers.   It's  also  useful  to  show  postings  on the checking account
-       together with the related account:
-
-              $ hledger register --related --invert assets:checking
-
-       With a reporting interval, register shows  summary  postings,  one  per
-       interval, aggregating the postings to each account:
-
-              $ hledger register --monthly income
-              2008/01                 income:salary                          $-1          $-1
-              2008/06                 income:gifts                           $-1          $-2
-
-       Periods  with no activity, and summary postings with a zero amount, are
-       not shown by default; use the --empty/-E flag to see them:
-
-              $ hledger register --monthly income -E
-              2008/01                 income:salary                          $-1          $-1
-              2008/02                                                          0          $-1
-              2008/03                                                          0          $-1
-              2008/04                                                          0          $-1
-              2008/05                                                          0          $-1
-              2008/06                 income:gifts                           $-1          $-2
-              2008/07                                                          0          $-2
-              2008/08                                                          0          $-2
-              2008/09                                                          0          $-2
-              2008/10                                                          0          $-2
-              2008/11                                                          0          $-2
-              2008/12                                                          0          $-2
-
-       Often, you'll want to see just one  line  per  interval.   The  --depth
-       option helps with this, causing subaccounts to be aggregated:
-
-              $ hledger register --monthly assets --depth 1h
-              2008/01                 assets                                  $1           $1
-              2008/06                 assets                                 $-1            0
-              2008/12                 assets                                 $-1          $-1
-
-       Note  when using report intervals, if you specify start/end dates these
-       will be adjusted outward if necessary to  contain  a  whole  number  of
-       intervals.   This  ensures  that  the first and last intervals are full
-       length and comparable to the others in the report.
-
-   Custom register output
-       register uses the full terminal width by default,  except  on  windows.
-       You  can override this by setting the COLUMNS environment variable (not
-       a bash shell variable) or by using the --width/-w option.
-
-       The description and account columns normally share  the  space  equally
-       (about  half  of  (width  - 40) each).  You can adjust this by adding a
-       description width  as  part  of  --width's  argument,  comma-separated:
-       --width W,D .  Here's a diagram (won't display correctly in --help):
-
-              <--------------------------------- width (W) ---------------------------------->
-              date (10)  description (D)       account (W-41-D)     amount (12)   balance (12)
-              DDDDDDDDDD dddddddddddddddddddd  aaaaaaaaaaaaaaaaaaa  AAAAAAAAAAAA  AAAAAAAAAAAA
-
-       and some examples:
-
-              $ hledger reg                     # use terminal width (or 80 on windows)
-              $ hledger reg -w 100              # use width 100
-              $ COLUMNS=100 hledger reg         # set with one-time environment variable
-              $ export COLUMNS=100; hledger reg # set till session end (or window resize)
-              $ hledger reg -w 100,40           # set overall width 100, description width 40
-              $ hledger reg -w $COLUMNS,40      # use terminal width, & description width 40
-
-       This  command  also  supports  the output destination and output format
-       options The output formats supported are txt, csv,  and  (experimental)
-       json.
-
-   register-match
-       register-match
-       Print the one posting whose transaction description is closest to DESC,
-       in the style of the register command.  If there  are  multiple  equally
-       good  matches,  it  shows the most recent.  Query options (options, not
-       arguments) can be used to restrict the  search  space.   Helps  ledger-
-       autosync detect already-seen transactions when importing.
-
-   rewrite
-       rewrite
-       Print all transactions, rewriting the postings of matched transactions.
-       For now the only rewrite available is adding new postings,  like  print
-       --auto.
-
-       This is a start at a generic rewriter of transaction entries.  It reads
-       the default journal and prints the transactions, like print,  but  adds
-       one or more specified postings to any transactions matching QUERY.  The
-       posting amounts can be fixed, or a multiplier of the existing  transac-
-       tion's first posting amount.
-
-       Examples:
-
-              $ hledger-rewrite.hs ^income --add-posting '(liabilities:tax)  *.33  ; income tax' --add-posting '(reserve:gifts)  $100'
-              $ hledger-rewrite.hs expenses:gifts --add-posting '(reserve:gifts)  *-1"'
-              $ hledger-rewrite.hs -f rewrites.hledger
-
-       rewrites.hledger may consist of entries like:
-
-              = ^income amt:<0 date:2017
-                (liabilities:tax)  *0.33  ; tax on income
-                (reserve:grocery)  *0.25  ; reserve 25% for grocery
-                (reserve:)  *0.25  ; reserve 25% for grocery
-
-       Note  the  single  quotes to protect the dollar sign from bash, and the
-       two spaces between account and amount.
-
-       More:
-
-              $ hledger rewrite -- [QUERY]        --add-posting "ACCT  AMTEXPR" ...
-              $ hledger rewrite -- ^income        --add-posting '(liabilities:tax)  *.33'
-              $ hledger rewrite -- expenses:gifts --add-posting '(budget:gifts)  *-1"'
-              $ hledger rewrite -- ^income        --add-posting '(budget:foreign currency)  *0.25 JPY; diversify'
-
-       Argument for --add-posting option is a  usual  posting  of  transaction
-       with  an  exception  for amount specification.  More precisely, you can
-       use '*' (star symbol) before the amount to indicate that that this is a
-       factor  for  an  amount  of  original  matched  posting.  If the amount
-       includes a commodity name, the new posting amount will be  in  the  new
-       commodity;  otherwise,  it will be in the matched posting amount's com-
-       modity.

-   Re-write rules in a file
-       During the run this tool will execute  so  called  "Automated  Transac-
-       tions" found in any journal it process.  I.e instead of specifying this
-       operations in command line you can put them in a journal file.
-
-              $ rewrite-rules.journal
-
-       Make contents look like this:
-
-              = ^income
-                  (liabilities:tax)  *.33
-
-              = expenses:gifts
-                  budget:gifts  *-1
-                  assets:budget  *1
-
-       Note that '=' (equality symbol) that is used instead of date in  trans-
-       actions you usually write.  It indicates the query by which you want to
-       match the posting to add new ones.
-
-              $ hledger rewrite -- -f input.journal -f rewrite-rules.journal > rewritten-tidy-output.journal
-
-       This is something similar to the commands pipeline:
-
-              $ hledger rewrite -- -f input.journal '^income' --add-posting '(liabilities:tax)  *.33' \
-                | hledger rewrite -- -f - expenses:gifts      --add-posting 'budget:gifts  *-1'       \
-                                                              --add-posting 'assets:budget  *1'       \
-                > rewritten-tidy-output.journal
-
-       It is important to understand that relative order of  such  entries  in
-       journal  is important.  You can re-use result of previously added post-
-       ings.
-
-   Diff output format
-       To use this tool for batch modification of your journal files  you  may
-       find useful output in form of unified diff.
-
-              $ hledger rewrite -- --diff -f examples/sample.journal '^income' --add-posting '(liabilities:tax)  *.33'
-
-       Output might look like:

-   rewrite vs. print --auto
-       This  command  predates  print --auto, and currently does much the same
-       thing, but with these differences:
-
-       o with multiple files, rewrite lets rules in any file affect all  other
-         files.   print  --auto  uses standard directive scoping; rules affect
-         only child files.
-
-       o rewrite's query limits which transactions can be rewritten;  all  are
-         printed.  print --auto's query limits which transactions are printed.
-
-       o rewrite applies rules specified on command line or  in  the  journal.
-         print --auto applies rules specified in the journal.
-
-   roi
-       roi
-       Shows  the  time-weighted (TWR) and money-weighted (IRR) rate of return
-       on your investments.
-
-       At a minimum, you need to supply  a  query  (which  could  be  just  an
-       account  name)  to  select  your  investment(s) with --inv, and another
-       query to identify your profit and loss transactions with --pnl.
-
-       If you do not record changes in the value of your investment  manually,
-       or  do  not  require  computation  of time-weighted return (TWR), --pnl
-       could be an empty query (--pnl "" or --pnl STR where STR does not match
-       any of your accounts).
-
-       This  command  will compute and display the internalized rate of return
-       (IRR) and time-weighted rate of return (TWR) for your  investments  for
-       the  time period requested.  Both rates of return are annualized before
-       display, regardless of the length of reporting interval.
-
-       Price directives will be taken into account if you  supply  appropriate
-       --cost or --value flags (see VALUATION).
-
-       Note, in some cases this report can fail, for these reasons:
-
-       o Error  (NotBracketed): No solution for Internal Rate of Return (IRR).
-         Possible causes: IRR  is  huge  (>1000000%),  balance  of  investment
-         becomes negative at some point in time.
-
-       o Error  (SearchFailed):  Failed  to find solution for Internal Rate of
-         Return (IRR).  Either search does not converge to a solution, or con-
-         verges too slowly.
-
-       Examples:
-
-       o Using   roi   to  compute  total  return  of  investment  in  stocks:
-         https://github.com/simonmichael/hledger/blob/master/examples/roi-
-         unrealised.ledger
-
-       o Cookbook -> Return on Investment
-
-   Spaces and special characters in --inv and --pnl
-       Note that --inv and --pnl's argument is a query, and queries could have
-       several space-separated terms (see QUERIES).
-
-       To indicate that all search terms form  single  command-line  argument,
-       you will need to put them in quotes (see Special characters):
-
-              $ hledger roi --inv 'term1 term2 term3 ...'
-
-       If  any  query  terms contain spaces themselves, you will need an extra
-       level of nested quoting, eg:
-
-              $ hledger roi --inv="'Assets:Test 1'" --pnl="'Equity:Unrealized Profit and Loss'"
-
-   Semantics of --inv and --pnl
-       Query supplied to --inv has to match all transactions that are  related
-       to your investment.  Transactions not matching --inv will be ignored.
-
-       In these transactions, ROI will conside postings that match --inv to be
-       "investment postings" and other postings (not matching --inv)  will  be
-       sorted  into  two categories: "cash flow" and "profit and loss", as ROI
-       needs to know which part of the investment value is your  contributions
-       and which is due to the return on investment.
-
-       o "Cash  flow"  is  depositing  or withdrawing money, buying or selling
-         assets, or otherwise converting between your investment commodity and
-         any other commodity.  Example:
-
-                2019-01-01 Investing in Snake Oil
-                  assets:cash          -$100
-                  investment:snake oil
-
-                2020-01-01 Selling my Snake Oil
-                  assets:cash           $10
-                  investment:snake oil  = 0
-
-       o "Profit and loss" is change in the value of your investment:
-
-                2019-06-01 Snake Oil falls in value
-                  investment:snake oil  = $57
-                  equity:unrealized profit or loss
-
-       All  non-investment postings are assumed to be "cash flow", unless they
-       match --pnl query.  Changes in value of your investment due to  "profit
-       and  loss"  postings  will  be  considered  as  part of your investment
-       return.
-
-       Example: if you use --inv snake --pnl equity:unrealized, then  postings
-       in the example below would be classifed as:
-
-              2019-01-01 Snake Oil #1
-                assets:cash          -$100   ; cash flow posting
-                investment:snake oil         ; investment posting
-
-              2019-03-01 Snake Oil #2
-                equity:unrealized pnl  -$100 ; profit and loss posting
-                snake oil                    ; investment posting
-
-              2019-07-01 Snake Oil #3
-                equity:unrealized pnl        ; profit and loss posting
-                cash          -$100          ; cash flow posting
-                snake oil     $50            ; investment posting

-   IRR and TWR explained
-       "ROI"  stands  for "return on investment".  Traditionally this was com-
-       puted as a difference between current value of investment and its  ini-
-       tial value, expressed in percentage of the initial value.
-
-       However, this approach is only practical in simple cases, where invest-
-       ments receives no in-flows or out-flows of money,  and  where  rate  of
-       growth is fixed over time.  For more complex scenarios you need differ-
-       ent ways to compute rate of return, and this command implements two  of
-       them: IRR and TWR.
-
-       Internal  rate of return, or "IRR" (also called "money-weighted rate of
-       return")  takes  into  account  effects  of  in-flows  and   out-flows.
-       Naively, if you are withdrawing from your investment, your future gains
-       would be smaller (in absolute numbers), and will be a smaller  percent-
-       age  of  your initial investment, and if you are adding to your invest-
-       ment, you will receive bigger absolute gains (but probably at the  same
-       rate  of  return).   IRR  is  a  way to compute rate of return for each
-       period between in-flow or out-flow of money, and then combine them in a
-       way  that gives you a compound annual rate of return that investment is
-       expected to generate.
-
-       As mentioned before, in-flows and out-flows would be any cash that  you
-       personally put in or withdraw, and for the "roi" command, these are the
-       postings that match the query in the--inv argument and  NOT  match  the
-       query in the--pnl argument.
-
-       If  you  manually  record  changes  in  the value of your investment as
-       transactions that balance them against "profit and loss"  (or  "unreal-
-       ized  gains") account or use price directives, then in order for IRR to
-       compute the precise effect of your in-flows and out-flows on  the  rate
-       of  return, you will need to record the value of your investement on or
-       close to the days when in- or out-flows occur.
-
-       In technical terms, IRR uses the same approach as  computation  of  net
-       present value, and tries to find a discount rate that makes net present
-       value of all the cash flows of your investment to add up to zero.  This
-       could  be hard to wrap your head around, especially if you haven't done
-       discounted cash flow analysis before.  Implementation of IRR in hledger
-       should produce results that match the XIRR formula in Excel.
-
-       Second  way  to  compute  rate of return that roi command implements is
-       called "time-weighted rate of return" or "TWR".  Like IRR, it will also
-       break  the  history  of  your investment into periods between in-flows,
-       out-flows and value changes, to compute rate of return per each  period
-       and  then a compound rate of return.  However, internal workings of TWR
-       are quite different.
-
-       TWR represents your investment as an imaginary "unit  fund"  where  in-
-       flows/  out-flows  lead to buying or selling "units" of your investment
-       and changes in its value change the value of "investment unit".  Change
-       in  "unit  price" over the reporting period gives you rate of return of
-       your investment.

-   stats
-       stats
-       Show some journal statistics.
-
-       The stats command displays summary information for the  whole  journal,
-       or  a matched part of it.  With a reporting interval, it shows a report
-       for each report period.
-
-       Example:
-
-              $ hledger stats
-              Main journal file        : /src/hledger/examples/sample.journal
-              Included journal files   :
-              Transactions span        : 2008-01-01 to 2009-01-01 (366 days)
-              Last transaction         : 2008-12-31 (2333 days ago)
-              Transactions             : 5 (0.0 per day)
-              Transactions last 30 days: 0 (0.0 per day)
-              Transactions last 7 days : 0 (0.0 per day)
-              Payees/descriptions      : 5
-              Accounts                 : 8 (depth 3)
-              Commodities              : 1 ($)
-              Market prices            : 12 ($)
-
-       This command also supports output destination and output format  selec-
-       tion.
-
-   tags
-       tags
-       List  the  unique tag names used in the journal.  With a TAGREGEX argu-
-       ment, only tag names matching the regular expression (case insensitive)
-       are  shown.  With QUERY arguments, only transactions matching the query
-       are considered.
-
-       With the --values flag, the tags' unique values are listed instead.
-
-       With --parsed flag, all tags or values are shown in the order they  are
-       parsed from the input data, including duplicates.
-
-       With  -E/--empty,  any blank/empty values will also be shown, otherwise
-       they are omitted.
-
-   test
-       test
-       Run built-in unit tests.
-
-       This command runs the unit tests built in to hledger  and  hledger-lib,
-       printing  the results on stdout.  If any test fails, the exit code will
-       be non-zero.
-
-       This is mainly used by hledger developers, but you can also use  it  to
-       sanity-check  the  installed  hledger executable on your platform.  All
-       tests are expected to pass - if you ever see a failure,  please  report
-       as a bug!
-
-       This command also accepts tasty test runner options, written after a --
-       (double hyphen).  Eg to run only the tests in Hledger.Data.Amount, with
-       ANSI colour codes disabled:
-
-              $ hledger test -- -pData.Amount --color=never
-
-       For  help  on these, see https://github.com/feuerbach/tasty#options (--
-       --help currently doesn't show them).
-
-   About add-on commands
-       Add-on commands are programs or scripts in your PATH
-
-       o whose name starts with hledger-
-
-       o whose name ends with a  recognised  file  extension:  .bat,.com,.exe,
-         .hs,.lhs,.pl,.py,.rb,.rkt,.sh or none
-
-       o and (on unix, mac) which are executable by the current user.
-
-       Add-ons  are  a relatively easy way to add local features or experiment
-       with new ideas.  They can be  written  in  any  language,  but  haskell
-       scripts  have  a  big  advantage: they can use the same hledger library
-       functions that built-in commands use for command-line options,  parsing
-       and  reporting.   Some experimental/example add-on scripts can be found
-       in the hledger repo's bin/ directory.
-
-       Note in a hledger command line, add-on command flags must have a double
-       dash (--) preceding them.  Eg you must write:
-
-              $ hledger web -- --serve
-
-       and not:
-
-              $ hledger web --serve
-
-       (because the --serve flag belongs to hledger-web, not hledger).
-
-       The -h/--help and --version flags don't require --.
-
-       If you have any trouble with this, remember you can always run the add-
-       on program directly, eg:
-
-              $ hledger-web --serve
-
-JOURNAL FORMAT
-       hledger's default file format, representing a General Journal.
-
-       hledger's usual data source is a plain  text  file  containing  journal
-       entries  in  hledger  journal  format.  This file represents a standard
-       accounting general journal.  I use file names ending in  .journal,  but
-       that's not required.  The journal file contains a number of transaction
-       entries, each describing a transfer of money (or any commodity) between
-       two or more named accounts, in a simple format readable by both hledger
-       and humans.
-
-       hledger's journal format is a compatible subset,  mostly,  of  ledger's
-       journal  format,  so  hledger  can  work with compatible ledger journal
-       files as well.  It's safe, and encouraged,  to  run  both  hledger  and
-       ledger on the same journal file, eg to validate the results you're get-
-       ting.
-
-       You can use hledger without learning any more about this file; just use
-       the add or web or import commands to create and update it.
-
-       Many users, though, edit the journal file with a text editor, and track
-       changes with a version control system such as git.  Editor addons  such
-       as  ledger-mode  or  hledger-mode  for  Emacs,  vim-ledger for Vim, and
-       hledger-vscode for Visual Studio Code, make this easier, adding colour,
-       formatting, tab completion, and useful commands.  See Editor configura-
-       tion at hledger.org for the full list.
-
-       Here's a description of each part of the  file  format  (and  hledger's
-       data  model).   These  are  mostly in the order you'll use them, but in
-       some cases related concepts have been grouped together for easy  refer-
-       ence,  or  linked before they are introduced, so feel free to skip over
-       anything that looks unnecessary right now.
-
-   Transactions
-       Transactions are the main unit of information in a journal file.   They
-       represent  events, typically a movement of some quantity of commodities
-       between two or more named accounts.
-
-       Each transaction is recorded as a journal entry, beginning with a  sim-
-       ple  date  in  column  0.  This can be followed by any of the following
-       optional fields, separated by spaces:
-
-       o a status character (empty, !, or *)
-
-       o a code (any short number or text, enclosed in parentheses)
-
-       o a description (any remaining text until end of line or a semicolon)
-
-       o a comment (any remaining text following  a  semicolon  until  end  of
-         line, and any following indented lines beginning with a semicolon)
-
-       o 0 or more indented posting lines, describing what was transferred and
-         the accounts involved (indented comment lines are also  allowed,  but
-         not blank lines or non-indented lines).
-
-       Here's a simple journal file containing one transaction:
-
-              2008/01/01 income
-                assets:bank:checking   $1
-                income:salary         $-1
-
-   Dates
-   Simple dates
-       Dates  in  the  journal  file  use  simple  dates format: YYYY-MM-DD or
-       YYYY/MM/DD or YYYY.MM.DD, with leading zeros optional.  The year may be
-       omitted,  in  which case it will be inferred from the context: the cur-
-       rent transaction, the default year set with a default  year  directive,
-       or   the  current  date  when  the  command  is  run.   Some  examples:
-       2010-01-31, 2010/01/31, 2010.1.31, 1/31.
-
-       (The UI also accepts simple dates, as well as the more  flexible  smart
-       dates documented in the hledger manual.)
-
-   Secondary dates
-       Real-life  transactions  sometimes  involve more than one date - eg the
-       date you write a cheque, and the date it clears in your bank.  When you
-       want  to  model this, for more accurate daily balances, you can specify
-       individual posting dates.
-
-       Or, you can use the older secondary date feature (Ledger calls it  aux-
-       iliary  date or effective date).  Note: we support this for compatibil-
-       ity, but I usually recommend avoiding this feature; posting  dates  are
-       almost always clearer and simpler.
-
-       A secondary date is written after the primary date, following an equals
-       sign.  If the year is omitted, the  primary  date's  year  is  assumed.
-       When  running  reports, the primary (left) date is used by default, but
-       with the --date2 flag (or --aux-date  or  --effective),  the  secondary
-       (right) date will be used instead.
-
-       The  meaning of secondary dates is up to you, but it's best to follow a
-       consistent rule.  Eg "primary = the bank's clearing date,  secondary  =
-       date the transaction was initiated, if different", as shown here:
-
-              2010/2/23=2/19 movie ticket
-                expenses:cinema                   $10
-                assets:checking
-
-              $ hledger register checking
-              2010-02-23 movie ticket         assets:checking                $-10         $-10
-
-              $ hledger register checking --date2
-              2010-02-19 movie ticket         assets:checking                $-10         $-10
-
-   Posting dates
-       You  can  give  individual  postings a different date from their parent
-       transaction, by adding a posting comment containing a tag  (see  below)
-       like date:DATE.  This is probably the best way to control posting dates
-       precisely.  Eg in  this  example  the  expense  should  appear  in  May
-       reports,  and the deduction from checking should be reported on 6/1 for
-       easy bank reconciliation:
-
-              2015/5/30
-                  expenses:food     $10  ; food purchased on saturday 5/30
-                  assets:checking        ; bank cleared it on monday, date:6/1
-
-              $ hledger -f t.j register food
-              2015-05-30                      expenses:food                  $10           $10
-
-              $ hledger -f t.j register checking
-              2015-06-01                      assets:checking               $-10          $-10
-
-       DATE should be a simple date; if the year is not specified it will  use
-       the  year  of  the  transaction's date.  You can set the secondary date
-       similarly, with date2:DATE2.  The date: or  date2:  tags  must  have  a
-       valid  simple  date  value  if they are present, eg a date: tag with no
-       value is not allowed.
-
-       Ledger's earlier, more compact bracketed date syntax is also supported:
-       [DATE],  [DATE=DATE2]  or  [=DATE2].  hledger will attempt to parse any
-       square-bracketed sequence of the 0123456789/-.= characters in this way.
-       With  this  syntax, DATE infers its year from the transaction and DATE2
-       infers its year from DATE.
-
-   Status
-       Transactions, or individual postings within a transaction, can  have  a
-       status  mark,  which  is  a  single  character  before  the transaction
-       description or posting account name, separated  from  it  by  a  space,
-       indicating one of three statuses:
-
-
-       mark     status
-       ------------------
-                unmarked
-       !        pending
-       *        cleared
-
-       When  reporting,  you  can  filter  by  status  with the -U/--unmarked,
-       -P/--pending, and -C/--cleared flags; or  the  status:,  status:!,  and
-       status:* queries; or the U, P, C keys in hledger-ui.
-
-       Note,  in Ledger and in older versions of hledger, the "unmarked" state
-       is called "uncleared".  As  of  hledger  1.3  we  have  renamed  it  to
-       unmarked for clarity.
-
-       To  replicate Ledger and old hledger's behaviour of also matching pend-
-       ing, combine -U and -P.
-
-       Status marks are optional, but can be helpful eg for  reconciling  with
-       real-world accounts.  Some editor modes provide highlighting and short-
-       cuts for working with status.  Eg in Emacs ledger-mode, you can  toggle
-       transaction status with C-c C-e, or posting status with C-c C-c.
-
-       What  "uncleared", "pending", and "cleared" actually mean is up to you.
-       Here's one suggestion:
-
-
-       status       meaning
-       --------------------------------------------------------------------------
-       uncleared    recorded but not yet reconciled; needs review
-       pending      tentatively reconciled (if needed, eg during a big reconcil-
-                    iation)
-       cleared      complete, reconciled as far as possible, and considered cor-
-                    rect
-
-       With this scheme, you would use -PC to see the current balance at  your
-       bank,  -U  to  see  things which will probably hit your bank soon (like
-       uncashed checks), and no flags to see the most up-to-date state of your
-       finances.
-
-   Code
-       After  the  status mark, but before the description, you can optionally
-       write a transaction "code", enclosed in parentheses.  This  is  a  good
-       place  to record a check number, or some other important transaction id
-       or reference number.
-
-   Description
-       A transaction's description is the rest of the line following the  date
-       and  status  mark  (or  until  a comment begins).  Sometimes called the
-       "narration" in traditional bookkeeping, it can be used for whatever you
-       wish,  or  left blank.  Transaction descriptions can be queried, unlike
-       comments.
-
-   Payee and note
-       You can optionally include a | (pipe) character in descriptions to sub-
-       divide the description into separate fields for payee/payer name on the
-       left (up to the first |) and an additional  note  field  on  the  right
-       (after  the  first  |).   This may be worthwhile if you need to do more
-       precise querying and pivoting by payee or by note.
-
-   Comments
-       Lines in the journal beginning with a semicolon (;) or hash (#) or star
-       (*)  are  comments, and will be ignored.  (Star comments cause org-mode
-       nodes to be ignored, allowing emacs users to fold  and  navigate  their
-       journals with org-mode or orgstruct-mode.)
-
-       You  can  attach  comments  to  a transaction by writing them after the
-       description and/or indented on the following lines  (before  the  post-
-       ings).   Similarly, you can attach comments to an individual posting by
-       writing them after the amount and/or indented on the  following  lines.
-       Transaction and posting comments must begin with a semicolon (;).
-
-       Some examples:
-
-              # a file comment
-              ; another file comment
-              * also a file comment, useful in org/orgstruct mode
-
-              comment
-              A multiline file comment, which continues
-              until a line containing just "end comment"
-              (or end of file).
-              end comment
-
-              2012/5/14 something  ; a transaction comment
-                  ; the transaction comment, continued
-                  posting1  1  ; a comment for posting 1
-                  posting2
-                  ; a comment for posting 2
-                  ; another comment line for posting 2
-              ; a file comment (because not indented)
-
-       You  can  also  comment  larger regions of a file using comment and end
-       comment directives.
-
-   Tags
-       Tags are a way to add extra labels or labelled  data  to  postings  and
-       transactions, which you can then search or pivot on.
-
-       A  simple  tag is a word (which may contain hyphens) followed by a full
-       colon, written inside a transaction or posting comment line:
-
-              2017/1/16 bought groceries  ; sometag:
-
-       Tags can have a value, which is the text after the  colon,  up  to  the
-       next comma or end of line, with leading/trailing whitespace removed:
-
-                  expenses:food    $10 ; a-posting-tag: the tag value
-
-       Note  this  means  hledger's  tag values can not contain commas or new-
-       lines.  Ending at commas means you can write multiple short tags on one
-       line, comma separated:
-
-                  assets:checking  ; a comment containing tag1:, tag2: some value ...
-
-       Here,
-
-       o "a comment containing" is just comment text, not a tag
-
-       o "tag1" is a tag with no value
-
-       o "tag2" is another tag, whose value is "some value ..."
-
-       Tags  in  a  transaction  comment affect the transaction and all of its
-       postings, while tags in a posting comment  affect  only  that  posting.
-       For  example, the following transaction has three tags (A, TAG2, third-
-       tag) and the posting has four (those plus posting-tag):
-
-              1/1 a transaction  ; A:, TAG2:
-                  ; third-tag: a third transaction tag, <- with a value
-                  (a)  $1  ; posting-tag:
-
-       Tags are like Ledger's metadata feature, except  hledger's  tag  values
-       are simple strings.
-
-   Postings
-       A  posting  is an addition of some amount to, or removal of some amount
-       from, an account.  Each posting line begins with at least one space  or
-       tab (2 or 4 spaces is common), followed by:
-
-       o (optional) a status character (empty, !, or *), followed by a space
-
-       o (required)  an  account  name (any text, optionally containing single
-         spaces, until end of line or a double space)
-
-       o (optional) two or more spaces or tabs followed by an amount.
-
-       Positive amounts are being added to the account, negative  amounts  are
-       being removed.
-
-       The amounts within a transaction must always sum up to zero.  As a con-
-       venience, one amount may be left blank; it will be inferred  so  as  to
-       balance the transaction.
-
-       Be  sure  to  note the unusual two-space delimiter between account name
-       and amount.  This makes it easy to write account names containing  spa-
-       ces.   But if you accidentally leave only one space (or tab) before the
-       amount, the amount will be considered part of the account name.
-
-   Virtual postings
-       A posting with a parenthesised account name is called a virtual posting
-       or  unbalanced  posting,  which  means it is exempt from the usual rule
-       that a transaction's postings must balance add up to zero.
-
-       This is not part of double entry accounting, so  you  might  choose  to
-       avoid  this  feature.   Or you can use it sparingly for certain special
-       cases where it can be convenient.  Eg, you could set  opening  balances
-       without using a balancing equity account:
-
-              1/1 opening balances
-                (assets:checking)   $1000
-                (assets:savings)    $2000
-
-       A  posting  with  a bracketed account name is called a balanced virtual
-       posting.  The balanced virtual postings in a transaction must add up to
-       zero (separately from other postings).  Eg:
-
-              1/1 buy food with cash, update budget envelope subaccounts, & something else
-                assets:cash                    $-10 ; <- these balance
-                expenses:food                    $7 ; <-
-                expenses:food                    $3 ; <-
-                [assets:checking:budget:food]  $-10    ; <- and these balance
-                [assets:checking:available]     $10    ; <-
-                (something:else)                 $5       ; <- not required to balance
-
-       Ordinary  non-parenthesised,  non-bracketed  postings  are  called real
-       postings.  You can exclude  virtual  postings  from  reports  with  the
-       -R/--real flag or real:1 query.
-
-   Account names
-       Account  names  typically have several parts separated by a full colon,
-       from which hledger derives a hierarchical chart of accounts.  They  can
-       be  anything you like, but in finance there are traditionally five top-
-       level accounts: assets, liabilities, revenue, expenses, and equity.
-
-       Account names may contain single spaces,  eg:  assets:accounts  receiv-
-       able.   Because  of  this,  they must always be followed by two or more
-       spaces (or newline).
-
-       Account names can be aliased.
-
-   Amounts
-       After the account  name,  there  is  usually  an  amount.   (Important:
-       between account name and amount, there must be two or more spaces.)
-
-       hledger's  amount  format is flexible, supporting several international
-       formats.  Here are some examples.  Amounts have a  number  (the  "quan-
-       tity"):
-
-              1
-
-       ..and usually a currency symbol or commodity name (more on this below),
-       to the left or right of the quantity,  with  or  without  a  separating
-       space:
-
-              $1
-              4000 AAPL
-              3 "green apples"
-
-       Amounts can be preceded by a minus sign (or a plus sign, though plus is
-       the default), The sign can be written before or after a left-side  com-
-       modity symbol:
-
-              -$1
-              $-1
-
-       One  or more spaces between the sign and the number are acceptable when
-       parsing (but they won't be displayed in output):
-
-              + $1
-              $-      1
-
-       Scientific E notation is allowed:
-
-              1E-6
-              EUR 1E3
-
-   Decimal marks, digit group marks
-       A decimal mark can be written as a period or a comma:
-
-              1.23
-              1,23456780000009
-
-       In the integer part of the quantity (left of the decimal mark),  groups
-       of  digits  can  optionally  be  separated  by a "digit group mark" - a
-       space, comma, or period (different from the decimal mark):
-
-                   $1,000,000.00
-                EUR 2.000.000,00
-              INR 9,99,99,999.00
-                    1 000 000.9455
-
-       Note, a number containing a single digit group mark and no decimal mark
-       is ambiguous.  Are these digit group marks or decimal marks ?
-
-              1,000
-              1.000
-
-       If  you  don't tell it otherwise, hledger will assume both of the above
-       are decimal marks, parsing both numbers as 1.  To prevent confusion and
-       undetected  typos,  we recommend adding commodity directives at the top
-       of your journal file  to  explicitly  declare  the  decimal  mark  (and
-       optionally  a  digit  group mark) for each commodity.  Read on for more
-       about this.
-
-   Commodity
-       Amounts in hledger have both a "quantity", which is  a  signed  decimal
-       number, and a "commodity", which is a currency symbol, stock ticker, or
-       any word or phrase describing something you are tracking.
-
-       If the commodity name contains non-letters (spaces, numbers, or punctu-
-       ation),  you must always write it inside double quotes ("green apples",
-       "ABC123").
-
-       If you write just a bare number, that too will have a  commodity,  with
-       name ""; we call that the "no-symbol commodity".
-
-       Actually,  hledger  combines  these  single-commodity amounts into more
-       powerful multi-commodity amounts, which are what it works with most  of
-       the  time.   A multi-commodity amount could be, eg: 1 USD, 2 EUR, 3.456
-       TSLA.  In practice,  you  will  only  see  multi-commodity  amounts  in
-       hledger's output; you can't write them directly in the journal file.
-
-       (If  you are writing scripts or working with hledger's internals, these
-       are the Amount and MixedAmount types.)
-
-   Commodity directives
-       You can add commodity directives to the journal, preferably at the top,
-       to  declare  your  commodities and help with number parsing (see above)
-       and display (see below).  These are optional,  but  recommended.   They
-       are  described  in  more detail in JOURNAL FORMAT -> Declaring commodi-
-       ties.  Here's a quick example:
-
-              # number format and display style for $, EUR, INR and the no-symbol commodity:
-              commodity $1,000.00
-              commodity EUR 1.000,00
-              commodity INR 9,99,99,999.00
-              commodity 1 000 000.9455
-
-
-   Commodity display style
-       For the amounts in each commodity, hledger chooses a consistent display
-       style  to  use  in  most  reports.  (Exceptions: price amounts, and all
-       amounts displayed by the print command, are displayed with all of their
-       decimal digits visible.)
-
-       A commodity's display style is inferred as follows.
-
-       First,  if  a  default commodity is declared with D, this commodity and
-       its style is applied to any no-symbol amounts in the journal.
-
-       Then each commodity's style is inferred from one of the  following,  in
-       order of preference:
-
-       o The  commodity  directive for that commodity (including the no-symbol
-         commodity), if any.
-
-       o The amounts in that commodity seen  in  the  journal's  transactions.
-         (Posting amounts only; prices and periodic or auto rules are ignored,
-         currently.)
-
-       o The built-in fallback style, which looks like this: $1000.00.   (Sym-
-         bol on the left, period decimal mark, two decimal places.)
-
-       A style is inferred from journal amounts as follows:
-
-       o Use  the  general style (decimal mark, symbol placement) of the first
-         amount
-
-       o Use the first-seen digit group style (digit group mark,  digit  group
-         sizes), if any
-
-       o Use the maximum number of decimal places of all.
-
-       Transaction  price  amounts  don't  affect  the commodity display style
-       directly, but occasionally they can do so indirectly (eg when  a  post-
-       ing's  amount is inferred using a transaction price).  If you find this
-       causing problems, use a commodity directive to fix the display style.
-
-       To summarise: each commodity's amounts will be normalised  to  (a)  the
-       style  declared by a commodity directive, or (b) the style of the first
-       posting amount in the journal, with the first-seen  digit  group  style
-       and  the maximum-seen number of decimal places.  So if your reports are
-       showing amounts in a way you don't  like,  eg  with  too  many  decimal
-       places, use a commodity directive.  Some examples:
-
-              # declare euro, dollar, bitcoin and no-symbol commodities and set their
-              # input number formats and output display styles:
-              commodity EUR 1.000,
-              commodity $1000.00
-              commodity 1000.00000000 BTC
-              commodity 1 000.
-
-   Rounding
-       Amounts are stored internally as decimal numbers with up to 255 decimal
-       places, and displayed with the number of decimal  places  specified  by
-       the  commodity display style.  Note, hledger uses banker's rounding: it
-       rounds to the nearest even number, eg 0.5 displayed with  zero  decimal
-       places  is  "0").   (Guaranteed since hledger 1.17.1; in older versions
-       this could vary if hledger was built with Decimal < 0.5.1.)
-
-   Transaction prices
-       Within a transaction, you can note an amount's price in another commod-
-       ity.   This can be used to document the cost (in a purchase) or selling
-       price (in a sale).  For  example,  transaction  prices  are  useful  to
-       record  purchases  of  a foreign currency.  Note transaction prices are
-       fixed at the time of the transaction, and do not change over time.  See
-       also market prices, which represent prevailing exchange rates on a cer-
-       tain date.
-
-       There are several ways to record a transaction price:
-
-       1. Write the price per unit, as @ UNITPRICE after the amount:
-
-                  2009/1/1
-                    assets:euros     EUR100 @ $1.35  ; one hundred euros purchased at $1.35 each
-                    assets:dollars                 ; balancing amount is -$135.00
-
-       2. Write the total price, as @@ TOTALPRICE after the amount:
-
-                  2009/1/1
-                    assets:euros     EUR100 @@ $135  ; one hundred euros purchased at $135 for the lot
-                    assets:dollars
-
-       3. Specify amounts for all postings, using exactly two commodities, and
-          let hledger infer the price that balances the transaction:
-
-                  2009/1/1
-                    assets:euros     EUR100          ; one hundred euros purchased
-                    assets:dollars  $-135          ; for $135
-
-       4. Like  1, but the @ is parenthesised, i.e.  (@); this is for compati-
-          bility with Ledger journals (Virtual posting costs), and is  equiva-
-          lent to 1 in hledger.
-
-       5. Like 2, but as in 4 the @@ is parenthesised, i.e.  (@@); in hledger,
-          this is equivalent to 2.
-
-       Use the -B/--cost flag to convert amounts to their transaction  price's
-       commodity, if any.  (mnemonic: "B" is from "cost Basis", as in Ledger).
-       Eg here is how -B affects the balance report for the example above:
-
-              $ hledger bal -N --flat
-                             $-135  assets:dollars
-                              EUR100  assets:euros
-              $ hledger bal -N --flat -B
-                             $-135  assets:dollars
-                              $135  assets:euros    # <- the euros' cost
-
-       Note -B is sensitive to the order of postings when a transaction  price
-       is  inferred:  the  inferred price will be in the commodity of the last
-       amount.  So if example 3's postings are reversed, while the transaction
-       is equivalent, -B shows something different:
-
-              2009/1/1
-                assets:dollars  $-135              ; 135 dollars sold
-                assets:euros     EUR100              ; for 100 euros
-
-              $ hledger bal -N --flat -B
-                             EUR-100  assets:dollars  # <- the dollars' selling price
-                              EUR100  assets:euros
-
-   Lot prices, lot dates
-       Ledger  allows  another kind of price, lot price (four variants: {UNIT-
-       PRICE},   {{TOTALPRICE}},   {=FIXEDUNITPRICE},   {{=FIXEDTOTALPRICE}}),
-       and/or a lot date ([DATE]) to be specified.  These are normally used to
-       select a lot when selling investments.  hledger will parse  these,  for
-       compatibility  with  Ledger  journals,  but  currently ignores them.  A
-       transaction price, lot price and/or lot date may appear in  any  order,
-       after the posting amount and before the balance assertion if any.
-
-   Balance assertions
-       hledger  supports  Ledger-style  balance  assertions  in journal files.
-       These look like, for example, = EXPECTEDBALANCE following  a  posting's
-       amount.   Eg  here  we assert the expected dollar balance in accounts a
-       and b after each posting:
-
-              2013/1/1
-                a   $1  =$1
-                b       =$-1
-
-              2013/1/2
-                a   $1  =$2
-                b  $-1  =$-2
-
-       After reading a journal file, hledger will check all balance assertions
-       and  report  an error if any of them fail.  Balance assertions can pro-
-       tect you from, eg, inadvertently disrupting reconciled  balances  while
-       cleaning  up  old  entries.   You can disable them temporarily with the
-       -I/--ignore-assertions flag, which can be useful for troubleshooting or
-       for  reading Ledger files.  (Note: this flag currently does not disable
-       balance assignments, below).
-
-   Assertions and ordering
-       hledger sorts an account's postings and assertions first  by  date  and
-       then  (for postings on the same day) by parse order.  Note this is dif-
-       ferent from Ledger, which sorts assertions only by parse order.  (Also,
-       Ledger  assertions  do not see the accumulated effect of repeated post-
-       ings to the same account within a transaction.)
-
-       So, hledger balance assertions keep working if you reorder differently-
-       dated  transactions  within the journal.  But if you reorder same-dated
-       transactions or postings, assertions might break and require  updating.
-       This order dependence does bring an advantage: precise control over the
-       order of postings and assertions within a day, so you can assert intra-
-       day balances.
-
-   Assertions and included files
-       With  included  files, things are a little more complicated.  Including
-       preserves the ordering of postings and assertions.  If you have  multi-
-       ple  postings  to  an  account  on the same day, split across different
-       files, and you also want to assert the account's balance  on  the  same
-       day, you'll have to put the assertion in the right file.
-
-   Assertions and multiple -f options
-       Balance assertions don't work well across files specified with multiple
-       -f options.  Use include or concatenate the files instead.
-
-   Assertions and commodities
-       The asserted balance must be a simple single-commodity amount,  and  in
-       fact  the  assertion  checks  only  this commodity's balance within the
-       (possibly multi-commodity) account balance.   This  is  how  assertions
-       work in Ledger also.  We could call this a "partial" balance assertion.
-
-       To assert the balance of more than one commodity in an account, you can
-       write multiple postings, each asserting one commodity's balance.
-
-       You  can  make a stronger "total" balance assertion by writing a double
-       equals sign (== EXPECTEDBALANCE).  This asserts that there are no other
-       unasserted commodities in the account (or, that their balance is 0).
-
-              2013/1/1
-                a   $1
-                a    1EUR
-                b  $-1
-                c   -1EUR
-
-              2013/1/2  ; These assertions succeed
-                a    0  =  $1
-                a    0  =   1EUR
-                b    0 == $-1
-                c    0 ==  -1EUR
-
-              2013/1/3  ; This assertion fails as 'a' also contains 1EUR
-                a    0 ==  $1
-
-       It's not yet possible to make a complete assertion about a balance that
-       has multiple commodities.  One workaround is to isolate each  commodity
-       into its own subaccount:
-
-              2013/1/1
-                a:usd   $1
-                a:euro   1EUR
-                b
-
-              2013/1/2
-                a        0 ==  0
-                a:usd    0 == $1
-                a:euro   0 ==  1EUR
-
-   Assertions and prices
-       Balance  assertions  ignore  transaction prices, and should normally be
-       written without one:
-
-              2019/1/1
-                (a)     $1 @ EUR1 = $1
-
-       We do allow prices to be written there, however, and print shows  them,
-       even  though  they  don't affect whether the assertion passes or fails.
-       This is for backward compatibility (hledger's  close  command  used  to
-       generate  balance  assertions with prices), and because balance assign-
-       ments do use them (see below).
-
-   Assertions and subaccounts
-       The balance assertions above (= and ==) do not count the  balance  from
-       subaccounts;  they check the account's exclusive balance only.  You can
-       assert the balance including subaccounts by writing =* or ==*, eg:
-
-              2019/1/1
-                equity:opening balances
-                checking:a       5
-                checking:b       5
-                checking         1  ==* 11
-
-   Assertions and virtual postings
-       Balance assertions are checked against all postings, both real and vir-
-       tual.  They are not affected by the --real/-R flag or real: query.
-
-   Assertions and precision
-       Balance  assertions  compare  the exactly calculated amounts, which are
-       not always what is shown by reports.   Eg  a  commodity  directive  may
-       limit  the  display  precision, but this will not affect balance asser-
-       tions.  Balance assertion failure messages show exact amounts.
-
-   Balance assignments
-       Ledger-style balance assignments are also supported.   These  are  like
-       balance  assertions, but with no posting amount on the left side of the
-       equals sign; instead it is calculated automatically so  as  to  satisfy
-       the  assertion.   This  can be a convenience during data entry, eg when
-       setting opening balances:
-
-              ; starting a new journal, set asset account balances
-              2016/1/1 opening balances
-                assets:checking            = $409.32
-                assets:savings             = $735.24
-                assets:cash                 = $42
-                equity:opening balances
-
-       or when adjusting a balance to reality:
-
-              ; no cash left; update balance, record any untracked spending as a generic expense
-              2016/1/15
-                assets:cash    = $0
-                expenses:misc
-
-       The calculated amount depends on the account's balance in the commodity
-       at  that  point  (which depends on the previously-dated postings of the
-       commodity to that account since the last balance assertion  or  assign-
-       ment).  Note that using balance assignments makes your journal a little
-       less explicit; to know the exact amount posted, you have to run hledger
-       or do the calculations yourself, instead of just reading it.
-
-   Balance assignments and prices
-       A  transaction  price in a balance assignment will cause the calculated
-       amount to have that price attached:
-
-              2019/1/1
-                (a)             = $1 @ EUR2
-
-              $ hledger print --explicit
-              2019-01-01
-                  (a)         $1 @ EUR2 = $1 @ EUR2
-
-   Directives
-       A directive is a line in the journal beginning with a special  keyword,
-       that influences how the journal is processed.  hledger's directives are
-       based on a subset of Ledger's, but there are many differences (and also
-       some differences between hledger versions).
-
-       Directives' behaviour and interactions can get a little bit complex, so
-       here is a table summarising the  directives  and  their  effects,  with
-       links to more detailed docs.

-       direc-   which  entries  and  (when there are multiple files) which files
-       tive     are affected by a directive
-       scope
-
-       As you can see, directives vary in which journal entries and files they
-       affect,  and  whether  they  are  focussed on input (parsing) or output
-       (reports).  Some directives have multiple effects.
-
-   Directives and multiple files
-       If you use  multiple  -f/--file  options,  or  the  include  directive,
-       hledger  will  process  multiple input files.  But note that directives
-       which affect input (see above) typically last only until the end of the
-       file in which they occur.
-
-       This may seem inconvenient, but it's intentional; it makes reports sta-
-       ble and deterministic, independent of the order  of  input.   Otherwise
-       you  could see different numbers if you happened to write -f options in
-       a different order, or if you moved includes around  while  cleaning  up
-       your files.
-
-       It  can  be  surprising though; for example, it means that alias direc-
-       tives do not affect parent or sibling files (see below).
-
-   Comment blocks
-       A line containing just comment starts a commented region of  the  file,
-       and a line containing just end comment (or the end of the current file)
-       ends it.  See also comments.
-
-   Including other files
-       You can pull in the content of additional files by writing  an  include
-       directive, like this:
-
-              include FILEPATH
-
-       Only  journal files can include, and only journal, timeclock or timedot
-       files can be included (not CSV files, currently).
-
-       If the file path does not begin with a slash, it  is  relative  to  the
-       current file's folder.
-
-       A tilde means home directory, eg: include ~/main.journal.
-
-       The path may contain glob patterns to match multiple files, eg: include
-       *.journal.
-
-       There is limited support for recursive wildcards:  **/  (the  slash  is
-       required)  matches 0 or more subdirectories.  It's not super convenient
-       since you have to avoid include cycles and including  directories,  but
-       this can be done, eg: include */**/*.journal.
-
-       The path may also be prefixed to force a specific file format, overrid-
-       ing the file extension (as described  in  hledger.1  ->  Input  files):
-       include timedot:~/notes/2020*.md.
-
-   Default year
-       You  can set a default year to be used for subsequent dates which don't
-       specify a year.  This is a line beginning with Y followed by the  year.
-       Eg:
-
-              Y2009  ; set default year to 2009
-
-              12/15  ; equivalent to 2009/12/15
-                expenses  1
-                assets
-
-              Y2010  ; change default year to 2010
-
-              2009/1/30  ; specifies the year, not affected
-                expenses  1
-                assets
-
-              1/31   ; equivalent to 2010/1/31
-                expenses  1
-                assets
-
-   Declaring payees
-       The  payee  directive  can  be  used to declare a limited set of payees
-       which may appear in transaction descriptions.  The "payees" check  will
-       report  an error if any transaction refers to a payee that has not been
-       declared.  Eg:
-
-              payee Whole Foods
-
-   Declaring commodities
-       You can use commodity directives to declare your commodities.  In  fact
-       the commodity directive performs several functions at once:
-
-       1. It  declares commodities which may be used in the journal.  This can
-          optionally be enforced, providing useful error checking.   (Cf  Com-
-          modity error checking)
-
-       2. It  declares  which  decimal  mark  character  (period or comma), to
-          expect when parsing input -  useful  to  disambiguate  international
-          number  formats in your data.  Without this, hledger will parse both
-          1,000 and 1.000 as 1.  (Cf Amounts)
-
-       3. It declares how to render the commodity's  amounts  when  displaying
-          output - the decimal mark, any digit group marks, the number of dec-
-          imal places, symbol placement and  so  on.   (Cf  Commodity  display
-          style)
-
-       You  will  run  into one of the problems solved by commodity directives
-       sooner or later, so we recommend using them, for robust and predictable
-       parsing and display.
-
-       Generally  you  should  put them at the top of your journal file (since
-       for function 2, they affect only following amounts, cf #793).
-
-       A commodity directive is just the word commodity followed by  a  sample
-       amount, like this:
-
-              ;commodity SAMPLEAMOUNT
-
-              commodity $1000.00
-              commodity 1,000.0000 AAAA  ; optional same-line comment
-
-       It  may also be written on multiple lines, and use the format subdirec-
-       tive, as in Ledger.  Note in this case  the  commodity  symbol  appears
-       twice; it must be the same in both places:
-
-              ;commodity SYMBOL
-              ;  format SAMPLEAMOUNT
-
-              ; display indian rupees with currency name on the left,
-              ; thousands, lakhs and crores comma-separated,
-              ; period as decimal point, and two decimal places.
-              commodity INR
-                format INR 1,00,00,000.00
-
-       Remember  that  if  the  commodity  symbol contains spaces, numbers, or
-       punctuation, it must be enclosed in double quotes (cf Commodity).
-
-       The amount's quantity does not matter; only the format is  significant.
-       It  must include a decimal mark - either a period or a comma - followed
-       by 0 or more decimal digits.
-
-       A few more examples:
-
-              # number formats for $, EUR, INR and the no-symbol commodity:
-              commodity $1,000.00
-              commodity EUR 1.000,00
-              commodity INR 9,99,99,999.0
-              commodity 1 000 000.
-
-       Note hledger normally uses banker's rounding,  so  0.5  displayed  with
-       zero decimal digits is "0".  (More at Commodity display style.)
-
-   Commodity error checking
-       In  strict mode, enabled with the -s/--strict flag, hledger will report
-       an error if a commodity symbol is used that has not been declared by  a
-       commodity  directive.   This works similarly to account error checking,
-       see the notes there for more details.
-
-   Default commodity
-       The D directive sets a default commodity, to be used for any subsequent
-       commodityless  amounts (ie, plain numbers) seen while parsing the jour-
-       nal.  This effect lasts until the next D directive, or the end  of  the
-       journal.
-
-       For  compatibility/historical  reasons,  D  also  acts like a commodity
-       directive (setting the commodity's decimal mark for parsing and display
-       style for output).
-
-       As  with  commodity,  the  amount  must  include a decimal mark (either
-       period or comma).  If both commodity and D directives are used for  the
-       same commodity, the commodity style takes precedence.
-
-       The syntax is D AMOUNT.  Eg:
-
-              ; commodity-less amounts should be treated as dollars
-              ; (and displayed with the dollar sign on the left, thousands separators and two decimal places)
-              D $1,000.00
-
-              1/1
-                a     5  ; <- commodity-less amount, parsed as $5 and displayed as $5.00
-                b
-
-   Declaring market prices
-       The  P  directive  declares  a  market price, which is an exchange rate
-       between two commodities on a certain date.  (In Ledger, they are called
-       "historical  prices".)  These are often obtained from a stock exchange,
-       cryptocurrency exchange, or the foreign exchange market.
-
-       The format is:
-
-              P DATE COMMODITY1SYMBOL COMMODITY2AMOUNT
-
-       DATE is a simple date, COMMODITY1SYMBOL is the symbol of the  commodity
-       being  priced, and COMMODITY2AMOUNT is the amount (symbol and quantity)
-       of commodity 2 that one unit of commodity 1  is  worth  on  this  date.
-       Examples:
-
-              # one euro was worth $1.35 from 2009-01-01 onward:
-              P 2009-01-01 EUR $1.35
-
-              # and $1.40 from 2010-01-01 onward:
-              P 2010-01-01 EUR $1.40
-
-       The  -V,  -X  and  --value flags use these market prices to show amount
-       values in another commodity.  See Valuation.
-
-   Declaring accounts
-       account directives can be used to declare accounts (ie, the places that
-       amounts  are transferred from and to).  Though not required, these dec-
-       larations can provide several benefits:
-
-       o They can document your intended chart of accounts, providing a refer-
-         ence.
-
-       o They  can  help  hledger know your accounts' types (asset, liability,
-         equity, revenue, expense), useful for reports like  balancesheet  and
-         incomestatement.
-
-       o They  control  account  display order in reports, allowing non-alpha-
-         betic sorting (eg Revenues to appear above Expenses).
-
-       o They can store extra information  about  accounts  (account  numbers,
-         notes, etc.)
-
-       o They  help  with account name completion in the add command, hledger-
-         iadd, hledger-web, ledger-mode etc.
-
-       o In strict mode, they restrict which accounts  may  be  posted  to  by
-         transactions, which helps detect typos.
-
-       The  simplest form is just the word account followed by a hledger-style
-       account name, eg this account directive declares the assets:bank:check-
-       ing account:
-
-              account assets:bank:checking
-
-   Account error checking
-       By  default, accounts come into existence when a transaction references
-       them by name.  This is convenient, but it means hledger can't warn  you
-       when you mis-spell an account name in the journal.  Usually you'll find
-       the error later, as an extra account in balance reports, or  an  incor-
-       rect balance when reconciling.
-
-       In  strict mode, enabled with the -s/--strict flag, hledger will report
-       an error if any transaction uses an account  name  that  has  not  been
-       declared by an account directive.  Some notes:
-
-       o The  declaration is case-sensitive; transactions must use the correct
-         account name capitalisation.
-
-       o The account directive's scope is "whole file and below"  (see  direc-
-         tives).  This means it affects all of the current file, and any files
-         it includes, but not  parent  or  sibling  files.   The  position  of
-         account directives within the file does not matter, though it's usual
-         to put them at the top.
-
-       o Accounts can only be declared  in  journal  files  (but  will  affect
-         included files in other formats).
-
-       o It's  currently  not  possible  to declare "all possible subaccounts"
-         with a wildcard; every account posted to must be declared.
-
-   Account comments
-       Comments, beginning with a semicolon, can be added:
-
-       o on the same line, after two or more spaces (because ; is  allowed  in
-         account names)
-
-       o on the next lines, indented
-
-       An example of both:
-
-              account assets:bank:checking  ; same-line comment, note 2+ spaces before ;
-                ; next-line comment
-                ; another with tag, acctno:12345 (not used yet)
-
-       Same-line comments are not supported by Ledger, or hledger <1.13.
-
-   Account subdirectives
-       We  also  allow  (and ignore) Ledger-style indented subdirectives, just
-       for compatibility.:
-
-              account assets:bank:checking
-                format blah blah  ; <- subdirective, ignored
-
-       Here is the full syntax of account directives:
-
-              account ACCTNAME  [ACCTTYPE] [;COMMENT]
-                [;COMMENTS]
-                [LEDGER-STYLE SUBDIRECTIVES, IGNORED]
-
-   Account types
-       hledger recognises five main types of  account,  corresponding  to  the
-       account classes in the accounting equation:
-
-       Asset, Liability, Equity, Revenue, Expense.
-
-       These account types are important for controlling which accounts appear
-       in the balancesheet, balancesheetequity, incomestatement  reports  (and
-       probably for other things in future).
-
-       Additionally,  we  recognise the Cash type, which is also an Asset, and
-       which causes accounts to appear in the cashflow report.   ("Cash"  here
-       means  liquid assets, eg bank balances but typically not investments or
-       receivables.)
-
-   Declaring account types
-       Generally, to make these reports work you should declare your top-level
-       accounts and their types, using account directives with type: tags.
-
-       The  tag's  value  should be one of: Asset, Liability, Equity, Revenue,
-       Expense, Cash, A, L, E, R, X, C (all case insensitive).   The  type  is
-       inherited  by  all subaccounts except where they override it.  Here's a
-       complete example:
-
-              account assets       ; type: Asset
-              account assets:bank  ; type: Cash
-              account assets:cash  ; type: Cash
-              account liabilities  ; type: Liability
-              account equity       ; type: Equity
-              account revenues     ; type: Revenue
-              account expenses     ; type: Expense
-
-   Auto-detected account types
-       If you happen to use common english top-level account  names,  you  may
-       not  need  to declare account types, as they will be detected automati-
-       cally using the following rules:
-
-               If account's name matches this regular expression:                 | its type is:
-              ------------------------------------------------------------------- | ------------
-               ^assets?(:|$)                                                      |
-                 and does not contain regexp (investment|receivable|:A/R|:fixed)  | Cash
-                 otherwise                                                        | Asset
-               ^(debts?|liabilit(y|ies))(:|$)                                     | Liability
-               ^equity(:|$)                                                       | Equity
-               ^(income|revenue)s?(:|$)                                           | Revenue
-               ^expenses?(:|$)                                                    | Expense
-
-       Even so, explicit declarations may be a good idea, for clarity and pre-
-       dictability.
-
-   Interference from auto-detected account types
-       If you assign any account type, it's a good idea to assign all of them,
-       to prevent any confusion from mixing declared and auto-detected  types.
-       Although  it's unlikely to happen in real life, here's an example: with
-       the following journal, balancesheetequity shows "liabilities"  in  both
-       Liabilities   and   Equity  sections.   Declaring  another  account  as
-       type:Liability would fix it:
-
-              account liabilities  ; type:Equity
-
-              2020-01-01
-                assets        1
-                liabilities   1
-                equity       -2
-
-   Old account type syntax
-       In some hledger journals you might instead see  this  old  syntax  (the
-       letters  ALERX, separated from the account name by two or more spaces);
-       this is deprecated and may be removed soon:
-
-              account assets       A
-              account liabilities  L
-              account equity       E
-              account revenues     R
-              account expenses     X
-
-   Account display order
-       Account directives also set the order in which accounts are  displayed,
-       eg  in  reports,  the  hledger-ui  accounts screen, and the hledger-web
-       sidebar.  By default accounts are listed in alphabetical order.  But if
-       you have these account directives in the journal:
-
-              account assets
-              account liabilities
-              account equity
-              account revenues
-              account expenses
-
-       you'll see those accounts displayed in declaration order, not alphabet-
-       ically:
-
-              $ hledger accounts -1
-              assets
-              liabilities
-              equity
-              revenues
-              expenses
-
-       Undeclared accounts, if any, are displayed last, in alphabetical order.
-
-       Note  that  sorting  is  done at each level of the account tree (within
-       each group of sibling accounts under the same parent).  And  currently,
-       this directive:
-
-              account other:zoo
-
-       would  influence the position of zoo among other's subaccounts, but not
-       the position of other among the top-level accounts.  This means:
-
-       o you will sometimes declare parent accounts (eg account  other  above)
-         that  you  don't  intend  to post to, just to customize their display
-         order
-
-       o sibling accounts stay together (you couldn't display x:y  in  between
-         a:b and a:c).
-
-   Rewriting accounts
-       You can define account alias rules which rewrite your account names, or
-       parts of them, before generating reports.  This can be useful for:
-
-       o expanding shorthand account names to their full form, allowing easier
-         data entry and a less verbose journal
-
-       o adapting old journals to your current chart of accounts
-
-       o experimenting with new account organisations, like a new hierarchy or
-         combining two accounts into one
-
-       o customising reports
-
-       Account aliases also rewrite account names in account directives.  They
-       do  not  affect account names being entered via hledger add or hledger-
-       web.
-
-       See also Rewrite account names.
-
-   Basic aliases
-       To set an account alias, use the alias directive in your journal  file.
-       This  affects all subsequent journal entries in the current file or its
-       included files (but note: not sibling or  parent  files).   The  spaces
-       around the = are optional:
-
-              alias OLD = NEW
-
-       Or, you can use the --alias 'OLD=NEW' option on the command line.  This
-       affects all entries.  It's useful for trying out aliases interactively.
-
-       OLD  and  NEW  are  case  sensitive  full  account names.  hledger will
-       replace any occurrence of the old account name with the new one.   Sub-
-       accounts are also affected.  Eg:
-
-              alias checking = assets:bank:wells fargo:checking
-              ; rewrites "checking" to "assets:bank:wells fargo:checking", or "checking:a" to "assets:bank:wells fargo:checking:a"
-
-   Regex aliases
-       There  is  also a more powerful variant that uses a regular expression,
-       indicated by the forward slashes:
-
-              alias /REGEX/ = REPLACEMENT
-
-       or --alias '/REGEX/=REPLACEMENT'.
-
-       REGEX is a case-insensitive regular expression.   Anywhere  it  matches
-       inside  an  account name, the matched part will be replaced by REPLACE-
-       MENT.  If REGEX contains parenthesised match groups, these can be  ref-
-       erenced by the usual numeric backreferences in REPLACEMENT.  Eg:
-
-              alias /^(.+):bank:([^:]+):(.*)/ = \1:\2 \3
-              ; rewrites "assets:bank:wells fargo:checking" to  "assets:wells fargo checking"
-
-       Also  note that REPLACEMENT continues to the end of line (or on command
-       line, to end of option argument), so it  can  contain  trailing  white-
-       space.
-
-   Combining aliases
-       You  can  define  as many aliases as you like, using journal directives
-       and/or command line options.
-
-       Recursive aliases - where an account name is rewritten  by  one  alias,
-       then  by  another  alias, and so on - are allowed.  Each alias sees the
-       effect of previously applied aliases.
-
-       In such cases it can be important to understand which aliases  will  be
-       applied  and  in  which order.  For (each account name in) each journal
-       entry, we apply:
-
-       1. alias directives preceding the journal entry, most  recently  parsed
-          first (ie, reading upward from the journal entry, bottom to top)
-
-       2. --alias  options,  in  the  order  they appeared on the command line
-          (left to right).
-
-       In other words, for (an account name in) a given journal entry:
-
-       o the nearest alias declaration before/above the entry is applied first
-
-       o the next alias before/above that will be be applied next, and so on
-
-       o aliases defined after/below the entry do not affect it.
-
-       This  gives nearby aliases precedence over distant ones, and helps pro-
-       vide semantic stability - aliases will keep working the same way  inde-
-       pendent of which files are being read and in which order.
-
-       In  case  of  trouble,  adding  --debug=6 to the command line will show
-       which aliases are being applied when.
-
-   Aliases and multiple files
-       As explained at Directives and multiple files, alias directives do  not
-       affect parent or sibling files.  Eg in this command,
-
-              hledger -f a.aliases -f b.journal
-
-       account  aliases  defined  in  a.aliases  will  not  affect  b.journal.
-       Including the aliases doesn't work either:
-
-              include a.aliases
-
-              2020-01-01  ; not affected by a.aliases
-                foo  1
-                bar
-
-       This means that account aliases should usually be declared at the start
-       of your top-most file, like this:
-
-              alias foo=Foo
-              alias bar=Bar
-
-              2020-01-01  ; affected by aliases above
-                foo  1
-                bar
-
-              include c.journal  ; also affected
-
-   end aliases
-       You  can  clear  (forget)  all  currently  defined aliases with the end
-       aliases directive:
-
-              end aliases
-
-   Default parent account
-       You can specify a  parent  account  which  will  be  prepended  to  all
-       accounts  within  a  section of the journal.  Use the apply account and
-       end apply account directives like so:
-
-              apply account home
-
-              2010/1/1
-                  food    $10
-                  cash
-
-              end apply account
-
-       which is equivalent to:
-
-              2010/01/01
-                  home:food           $10
-                  home:cash          $-10
-
-       If end apply account is omitted, the effect lasts to  the  end  of  the
-       file.  Included files are also affected, eg:
-
-              apply account business
-              include biz.journal
-              end apply account
-              apply account personal
-              include personal.journal
-
-       Prior  to  hledger 1.0, legacy account and end spellings were also sup-
-       ported.
-
-       A default parent account also affects account directives.  It does  not
-       affect  account names being entered via hledger add or hledger-web.  If
-       account aliases are present, they are applied after the default  parent
-       account.
-
-   Periodic transactions
-       Periodic  transaction  rules  describe  transactions  that recur.  They
-       allow hledger to generate temporary future transactions  to  help  with
-       forecasting,  so  you  don't have to write out each one in the journal,
-       and it's easy to try out different forecasts.
-
-       Periodic transactions can be a little tricky, so before you  use  them,
-       read this whole section - or at least these tips:
-
-       1. Two  spaces  accidentally  added or omitted will cause you trouble -
-          read about this below.
-
-       2. For troubleshooting, show the generated  transactions  with  hledger
-          print   --forecast  tag:generated  or  hledger  register  --forecast
-          tag:generated.
-
-       3. Forecasted transactions will begin only  after  the  last  non-fore-
-          casted transaction's date.
-
-       4. Forecasted  transactions  will  end 6 months from today, by default.
-          See below for the exact start/end rules.
-
-       5. period  expressions  can  be  tricky.   Their  documentation   needs
-          improvement, but is worth studying.
-
-       6. Some  period  expressions  with a repeating interval must begin on a
-          natural boundary of that interval.  Eg in  weekly  from  DATE,  DATE
-          must  be a monday.  ~ weekly from 2019/10/1 (a tuesday) will give an
-          error.
-
-       7. Other period expressions with an interval are automatically expanded
-          to  cover a whole number of that interval.  (This is done to improve
-          reports, but it also affects periodic transactions.  Yes, it's a bit
-          inconsistent  with  the  above.)  Eg: ~ every 10th day of month from
-          2020/01, which is equivalent to ~  every  10th  day  of  month  from
-          2020/01/01, will be adjusted to start on 2019/12/10.
-
-       Periodic transaction rules also have a second meaning: they are used to
-       define budget goals, shown in budget reports.
-
-   Periodic rule syntax
-       A periodic transaction rule looks like a normal journal entry, with the
-       date replaced by a tilde (~) followed by a period expression (mnemonic:
-       ~ looks like a recurring sine wave.):
-
-              ~ monthly
-                  expenses:rent          $2000
-                  assets:bank:checking
-
-       There is an additional constraint on the period expression:  the  start
-       date  must fall on a natural boundary of the interval.  Eg monthly from
-       2018/1/1 is valid, but monthly from 2018/1/15 is not.
-
-       Partial or relative dates (M/D, D, tomorrow, last week) in  the  period
-       expression  can work (useful or not).  They will be relative to today's
-       date, unless a Y default year directive is in  effect,  in  which  case
-       they will be relative to Y/1/1.
-
-   Two spaces between period expression and description!
-       If  the  period  expression  is  followed by a transaction description,
-       these must be separated by two or more spaces.  This helps hledger know
-       where the period expression ends, so that descriptions can not acciden-
-       tally alter their meaning, as in this example:
-
-              ; 2 or more spaces needed here, so the period is not understood as "every 2 months in 2020"
-              ;               ||
-              ;               vv
-              ~ every 2 months  in 2020, we will review
-                  assets:bank:checking   $1500
-                  income:acme inc
-
-       So,
-
-       o Do write two spaces between your period expression and your  transac-
-         tion description, if any.
-
-       o Don't  accidentally  write  two  spaces  in the middle of your period
-         expression.
-
-   Forecasting with periodic transactions
-       The --forecast flag activates any periodic  transaction  rules  in  the
-       journal.   They  will  generate temporary recurring transactions, which
-       are not saved in the journal,  but  will  appear  in  all  reports  (eg
-       print).  This can be useful for estimating balances into the future, or
-       experimenting with different scenarios.  Or, it can be used as  a  data
-       entry aid: describe recurring transactions, and every so often copy the
-       output of print --forecast into the journal.
-
-       These transactions will have an extra  tag  indicating  which  periodic
-       rule generated them: generated-transaction:~ PERIODICEXPR.  And a simi-
-       lar, hidden tag (beginning with  an  underscore)  which,  because  it's
-       never  displayed  by print, can be used to match transactions generated
-       "just now": _generated-transaction:~ PERIODICEXPR.
-
-       Periodic transactions are generated within some  forecast  period.   By
-       default, this
-
-       o begins on the later of
-
-         o the report start date if specified with -b/-p/date:
-
-         o the  day  after the latest normal (non-periodic) transaction in the
-           journal, or today if there are no normal transactions.
-
-       o ends on the report end date  if  specified  with  -e/-p/date:,  or  6
-         months (180 days) from today.
-
-       This  means that periodic transactions will begin only after the latest
-       recorded transaction.  And a recorded transaction dated in  the  future
-       can  prevent  generation of periodic transactions.  (You can avoid that
-       by writing the future transaction as a one-time periodic rule instead -
-       put tilde before the date, eg ~ YYYY-MM-DD ...).
-
-       Or, you can set your own arbitrary "forecast period", which can overlap
-       recorded transactions, and need not be in the future, by  providing  an
-       option  argument,  like --forecast=PERIODEXPR.  Note the equals sign is
-       required, a space won't work.  PERIODEXPR is a period expression, which
-       can  specify  the start date, end date, or both, like in a date: query.
-       (See also hledger.1 ->  Report  start  &  end  date).   Some  examples:
-       --forecast=202001-202004, --forecast=jan-, --forecast=2020.
-
-   Budgeting with periodic transactions
-       With  the  --budget  flag,  currently supported by the balance command,
-       each periodic transaction rule declares recurring budget goals for  the
-       specified  accounts.   Eg  the  first  example above declares a goal of
-       spending $2000 on rent (and also,  a  goal  of  depositing  $2000  into
-       checking)  every  month.  Goals and actual performance can then be com-
-       pared in budget reports.
-
-       See also: Budgeting and Forecasting.
-
-
-   Auto postings
-       "Automated postings" or "auto postings" are extra  postings  which  get
-       added  automatically  to  transactions  which  match  certain  queries,
-       defined by "auto posting rules", when you use the --auto flag.
-
-       An auto posting rule looks a bit like a transaction:
-
-              = QUERY
-                  ACCOUNT  AMOUNT
-                  ...
-                  ACCOUNT  [AMOUNT]
-
-       except the first line is an equals sign (mnemonic:  =  suggests  match-
-       ing),  followed  by a query (which matches existing postings), and each
-       "posting" line describes a posting to be  generated,  and  the  posting
-       amounts can be:
-
-       o a  normal  amount  with a commodity symbol, eg $2.  This will be used
-         as-is.
-
-       o a number, eg 2.  The commodity symbol (if any) from the matched post-
-         ing will be added to this.
-
-       o a  numeric  multiplier,  eg  *2 (a star followed by a number N).  The
-         matched posting's amount (and total price, if any) will be multiplied
-         by N.
-
-       o a  multiplier  with a commodity symbol, eg *$2 (a star, number N, and
-         symbol S).  The matched posting's amount will be multiplied by N, and
-         its commodity symbol will be replaced with S.
-
-       Any  query  term containing spaces must be enclosed in single or double
-       quotes, as on the command line.  Eg, note the quotes around the  second
-       query term below:
-
-              = expenses:groceries 'expenses:dining out'
-                  (budget:funds:dining out)                 *-1
-
-       Some examples:
-
-              ; every time I buy food, schedule a dollar donation
-              = expenses:food
-                  (liabilities:charity)   $-1
-
-              ; when I buy a gift, also deduct that amount from a budget envelope subaccount
-              = expenses:gifts
-                  assets:checking:gifts  *-1
-                  assets:checking         *1
-
-              2017/12/1
-                expenses:food    $10
-                assets:checking
-
-              2017/12/14
-                expenses:gifts   $20
-                assets:checking
-
-              $ hledger print --auto
-              2017-12-01
-                  expenses:food              $10
-                  assets:checking
-                  (liabilities:charity)      $-1

-   Auto postings and multiple files
-       An auto posting rule can affect any transaction in the current file, or
-       in any parent file or child file.  Note, currently it will  not  affect
-       sibling files (when multiple -f/--file are used - see #1212).
-
-   Auto postings and dates
-       A  posting  date (or secondary date) in the matched posting, or (taking
-       precedence) a posting date in the auto posting rule itself,  will  also
-       be used in the generated posting.
-
-   Auto postings and transaction balancing / inferred amounts / balance asser-
-       tions
-       Currently, auto postings are added:
-
-       o after missing amounts are inferred, and transactions are checked  for
-         balancedness,
-
-       o but before balance assertions are checked.
-
-       Note  this  means that journal entries must be balanced both before and
-       after auto postings are added.  This changed in hledger 1.12+; see #893
-       for background.
-
-   Auto posting tags
-       Automated postings will have some extra tags:
-
-       o generated-posting:= QUERY - shows this was generated by an auto post-
-         ing rule, and the query
-
-       o _generated-posting:= QUERY - a hidden tag, which does not  appear  in
-         hledger's output.  This can be used to match postings generated "just
-         now", rather than generated in the past and saved to the journal.
-
-       Also, any transaction that has been changed by auto posting rules  will
-       have these tags added:
-
-       o modified: - this transaction was modified
-
-       o _modified: - a hidden tag not appearing in the comment; this transac-
-         tion was modified "just now".
-
-CSV FORMAT
-       How hledger reads CSV data, and the CSV rules file format.
-
-       hledger can read CSV files (Character Separated Value - usually  comma,
-       semicolon,  or  tab)  containing  dated records as if they were journal
-       files, automatically converting each CSV record into a transaction.
-
-       (To learn about writing CSV, see CSV output.)
-
-       We describe each CSV file's format with a corresponding rules file.  By
-       default  this is named like the CSV file with a .rules extension added.
-       Eg when reading FILE.csv, hledger also looks for FILE.csv.rules in  the
-       same  directory  as  FILE.csv.   You can specify a different rules file
-       with the --rules-file option.  If a rules file is  not  found,  hledger
-       will create a sample rules file, which you'll need to adjust.
-
-       This  file  contains rules describing the CSV data (header line, fields
-       layout, date format etc.), and how to construct hledger journal entries
-       (transactions) from it.  Often there will also be a list of conditional
-       rules  for  categorising  transactions  based  on  their  descriptions.
-       Here's  an  overview  of  the CSV rules; these are described more fully
-       below, after the examples:
-
-
-       skip                         skip one or more header lines or matched CSV
-                                    records
-
-
-       fields list                  name  CSV  fields,  assign  them  to hledger
-                                    fields
-       field assignment             assign a value to one  hledger  field,  with
-                                    interpolation
-       Field names                  hledger field names, used in the fields list
-                                    and field assignments
-       separator                    a custom field separator
-       if block                     apply some rules to CSV records  matched  by
-                                    patterns
-       if table                     apply  some  rules to CSV records matched by
-                                    patterns, alternate syntax
-       end                          skip the remaining CSV records
-       date-format                  how to parse dates in CSV records
-       decimal-mark                 the decimal mark used  in  CSV  amounts,  if
-                                    ambiguous
-       newest-first                 disambiguate  record order when there's only
-                                    one date
-       include                      inline another CSV rules file
-       balance-type                 choose which type of balance assignments  to
-                                    use
-
-       Note,  for best error messages when reading CSV files, use a .csv, .tsv
-       or .ssv file extension or file prefix - see File Extension below.
-
-       There's an introductory Convert CSV files tutorial on hledger.org.
-
-   Examples
-       Here are some sample hledger CSV rules files.  See also the  full  col-
-       lection at:
-       https://github.com/simonmichael/hledger/tree/master/examples/csv
-
-   Basic
-       At  minimum,  the  rules file must identify the date and amount fields,
-       and often it also specifies the date format and how many  header  lines
-       there are.  Here's a simple CSV file and a rules file for it:
-
-              Date, Description, Id, Amount
-              12/11/2019, Foo, 123, 10.23
-
-              # basic.csv.rules
-              skip         1
-              fields       date, description, _, amount
-              date-format  %d/%m/%Y
-
-              $ hledger print -f basic.csv
-              2019-11-12 Foo
-                  expenses:unknown           10.23
-                  income:unknown            -10.23
-
-       Default account names are chosen, since we didn't set them.
-
-   Bank of Ireland
-       Here's  a  CSV with two amount fields (Debit and Credit), and a balance
-       field, which we can use to add balance assertions, which is not  neces-
-       sary but provides extra error checking:
-
-              Date,Details,Debit,Credit,Balance
-              07/12/2012,LODGMENT       529898,,10.0,131.21
-              07/12/2012,PAYMENT,5,,126
-
-              # bankofireland-checking.csv.rules
-
-              # skip the header line

-
-              # name the csv fields, and assign some of them as journal entry fields
-              fields  date, description, amount-out, amount-in, balance
-
-              # We generate balance assertions by assigning to "balance"
-              # above, but you may sometimes need to remove these because:
-              #
-              # - the CSV balance differs from the true balance,
-              #   by up to 0.0000000000005 in my experience
-              #
-              # - it is sometimes calculated based on non-chronological ordering,
-              #   eg when multiple transactions clear on the same day
-
-              # date is in UK/Ireland format
-              date-format  %d/%m/%Y
-

-              # set the base account for all txns
-              account1  assets:bank:boi:checking
-
-              $ hledger -f bankofireland-checking.csv print
-              2012-12-07 LODGMENT       529898
-                  assets:bank:boi:checking         EUR10.0 = EUR131.2

-                  expenses:unknown                  EUR5.0
-
-       The  balance assertions don't raise an error above, because we're read-
-       ing directly from CSV, but they will be checked if  these  entries  are
-       imported into a journal file.
-
-   Amazon
-       Here we convert amazon.com order history, and use an if block to gener-
-       ate a third posting if there's a fee.  (In practice you'd probably  get
-       this data from your bank instead, but it's an example.)

-
-   CSV rules
-       The following kinds of rule can appear in the rules file, in any order.
-       Blank lines and lines beginning with # or ; are ignored.
-
-   skip
-              skip N
-
-       The  word  "skip"  followed by a number (or no number, meaning 1) tells
-       hledger to ignore this many non-empty lines  preceding  the  CSV  data.
-       (Empty/blank  lines  are skipped automatically.) You'll need this when-
-       ever your CSV data contains header lines.
-
-       It also has a second purpose: it can be used inside if blocks to ignore
-       certain CSV records (described below).
-
-   fields list
-              fields FIELDNAME1, FIELDNAME2, ...
-
-       A  fields  list  (the  word  "fields" followed by comma-separated field
-       names) is the quick way to assign CSV field values to  hledger  fields.
-       (The  other  way  is  field assignments, see below.) A fields list does
-       does two things:
-
-       1. It names the CSV fields.  This is optional, but  can  be  convenient
-          later for interpolating them.
-
-       2. Whenever  you use a standard hledger field name (defined below), the
-          CSV value is assigned to that part of the hledger transaction.
-
-       Here's an example that says "use the 1st, 2nd and  4th  fields  as  the
-       transaction's  date,  description  and amount; name the last two fields
-       for later reference; and ignore the others":
-
-              fields date, description, , amount, , , somefield, anotherfield
-
-       Tips:
-
-       o The fields list always use commas, even if your CSV data uses another
-         separator character.
-
-       o Currently  there  must  be  least two items in the list (at least one
-         comma).
-
-       o Field names may not contain spaces.  Spaces before/after field  names
-         are optional.
-
-       o If  the  CSV contains column headings, it's a good idea to use these,
-         suitably modified, as the basis for your field names (eg lower-cased,
-         with underscores instead of spaces).
-
-       o If  some  heading  names match standard hledger fields, but you don't
-         want to set the hledger fields directly, alter  those  names,  eg  by
-         appending an underscore.
-
-       o Fields you don't care about can be given a dummy name (eg: _ ), or no
-         name.
-
-   field assignment
-              HLEDGERFIELDNAME FIELDVALUE
-
-       Field assignments are the more flexible way to  assign  CSV  values  to
-       hledger fields.  They can be used instead of or in addition to a fields
-       list (see above).
-
-       To assign a value to a hledger field, write the field name (any of  the
-       standard  hledger  field/pseudo-field  names,  defined below), a space,
-       followed by a text value on the same line.  This text value may  inter-
-       polate  CSV  fields,  referenced  by  their 1-based position in the CSV
-       record (%N), or by the name they were given in the fields  list  (%CSV-
-       FIELDNAME).
-
-       Some examples:
-
-              # set the amount to the 4th CSV field, with " USD" appended
-              amount %4 USD
-
-              # combine three fields to make a comment, containing note: and date: tags
-              comment note: %somefield - %anotherfield, date: %1
-
-       Tips:
-
-       o Interpolation  strips  outer  whitespace  (so  a CSV value like " 1 "
-         becomes 1 when interpolated) (#1051).
-
-       o See also Tips below.
-
-   Field names
-       Here are the standard hledger field (and pseudo-field) names, which you
-       can  use in a fields list and in field assignments.  For more about the
-       transaction parts they refer to, see Transactions.
-
-   date field
-       Assigning to date sets the transaction date.
-
-   date2 field
-       date2 sets the transaction's secondary date, if any.
-
-   status field
-       status sets the transaction's status, if any.
-
-   code field
-       code sets the transaction's code, if any.
-
-   description field
-       description sets the transaction's description, if any.
-
-   comment field
-       comment sets the transaction's comment, if any.
-
-       commentN, where N is a number, sets the Nth posting's comment.
-
-       Tips: - Only single-line comments can be assigned.  - Comments can con-
-       tain tags, as usual.
-
-   account field
-       Assigning to accountN, where N is 1 to 99, sets the account name of the
-       Nth posting, and causes that posting to be generated.
-
-       Most often there are two postings, so you'll want to set  account1  and
-       account2.   Typically  account1 is associated with the CSV file, and is
-       set once with a top-level assignment, while account2 is  set  based  on
-       each transaction's description, and in conditional blocks.
-
-       If  a  posting's  account name is left unset but its amount is set (see
-       below), a default account name will be chosen (like  "expenses:unknown"
-       or "income:unknown").
-
-   amount field
-       amountN  sets the amount of the Nth posting, and causes that posting to
-       be generated.  By assigning to amount1, amount2,  ...   etc.   you  can
-       generate up to 99 postings.
-
-       amountN-in  and  amountN-out can be used instead, if the CSV uses sepa-
-       rate fields for debits and credits  (inflows  and  outflows).   hledger
-       assumes  both  of these CSV fields are unsigned, and will automatically
-       negate the "-out" value.  If they are  signed,  see  "Setting  amounts"
-       below.
-
-       amount,  or  amount-in  and  amount-out are a legacy mode, to keep pre-
-       hledger-1.17 CSV rules files working (and for occasional  convenience).
-       They  are  suitable  only  for  two-posting transactions; they set both
-       posting 1's and  posting  2's  amount.   Posting  2's  amount  will  be
-       negated, and also converted to cost if there's a transaction price.
-
-       If you have an existing rules file using the unnumbered form, you might
-       want to use the numbered form in certain  conditional  blocks,  without
-       having  to  update  and  retest all the old rules.  To facilitate this,
-       posting   1   ignores    amount/amount-in/amount-out    if    any    of
-       amount1/amount1-in/amount1-out are assigned, and posting 2 ignores them
-       if any of amount2/amount2-in/amount2-out are  assigned,  avoiding  con-
-       flicts.
-
-   currency field
-       currency  sets  a  currency  symbol,  to  be prepended to all postings'
-       amounts.  You can use this if the CSV amounts do not  have  a  currency
-       symbol, eg if it is in a separate column.
-
-       currencyN  prepends a currency symbol to just the Nth posting's amount.
-
-   balance field
-       balanceN sets a balance assertion amount (or if the posting  amount  is
-       left empty, a balance assignment) on posting N.
-
-       balance is a compatibility spelling for hledger <1.17; it is equivalent
-       to balance1.
-
-       You can adjust the type of assertion/assignment with  the  balance-type
-       rule (see below).
-
-       See Tips below for more about setting amounts and currency.
-
-   separator
-       You  can  use the separator rule to read other kinds of character-sepa-
-       rated data.  The argument is any single  separator  character,  or  the
-       words  tab or space (case insensitive).  Eg, for comma-separated values
-       (CSV):
-
-              separator ,
-
-       or for semicolon-separated values (SSV):
-
-              separator ;
-
-       or for tab-separated values (TSV):
-
-              separator TAB
-
-       If the input file has a .csv, .ssv or .tsv file extension (or  a  csv:,
-       ssv:, tsv: prefix), the appropriate separator will be inferred automat-
-       ically, and you won't need this rule.
-
-   if block
-              if MATCHER
-               RULE
-
-              if
-              MATCHER
-              MATCHER
-              MATCHER
-               RULE
-               RULE
-
-       Conditional blocks ("if blocks") are a block of rules that are  applied
-       only  to CSV records which match certain patterns.  They are often used
-       for customising account names based on transaction descriptions.
-
-   Matching the whole record
-       Each MATCHER can be a record matcher, which looks like this:
-
-              REGEX
-
-       REGEX is a case-insensitive regular expression that tries to match any-
-       where  within  the  CSV  record.   It  is a POSIX ERE (extended regular
-       expression) that also supports GNU word boundaries (\b,  \B,  \<,  \>),
-       and  nothing  else.   If  you  have  trouble, be sure to check our doc:
-       https://hledger.org/hledger.html#regular-expressions
-
-       Important note: the record that is matched is not the original  record,
-       but  a synthetic one, with any enclosing double quotes (but not enclos-
-       ing whitespace) removed, and always comma-separated (which means that a
-       field  containing  a  comma  will  appear like two fields).  Eg, if the
-       original record is 2020-01-01; "Acme, Inc.";   1,000,  the  REGEX  will
-       actually see 2020-01-01,Acme, Inc.,  1,000).
-
-   Matching individual fields
-       Or, MATCHER can be a field matcher, like this:
-
-              %CSVFIELD REGEX
-
-       which  matches just the content of a particular CSV field.  CSVFIELD is
-       a percent sign followed by the field's  name  or  column  number,  like
-       %date or %1.
-
-   Combining matchers
-       A single matcher can be written on the same line as the "if"; or multi-
-       ple matchers can be written on the following lines, non-indented.  Mul-
-       tiple  matchers are OR'd (any one of them can match), unless one begins
-       with an & symbol, in which case it is AND'ed with the previous matcher.
-
-              if
-              MATCHER
-              & MATCHER
-               RULE
-
-   Rules applied on successful match
-       After  the  patterns  there  should  be one or more rules to apply, all
-       indented by at least one space.  Three kinds of  rule  are  allowed  in
-       conditional blocks:
-
-       o field assignments (to set a hledger field)
-
-       o skip (to skip the matched CSV record)
-
-       o end (to skip all remaining CSV records).
-
-       Examples:
-
-              # if the CSV record contains "groceries", set account2 to "expenses:groceries"
-              if groceries
-               account2 expenses:groceries
-
-              # if the CSV record contains any of these patterns, set account2 and comment as shown
-              if
-              monthly service fee
-              atm transaction fee
-              banking thru software
-               account2 expenses:business:banking
-               comment  XXX deductible ? check it
-
-   if table
-              if,CSVFIELDNAME1,CSVFIELDNAME2,...,CSVFIELDNAMEn
-              MATCHER1,VALUE11,VALUE12,...,VALUE1n
-              MATCHER2,VALUE21,VALUE22,...,VALUE2n
-              MATCHER3,VALUE31,VALUE32,...,VALUE3n
-              <empty line>
-
-       Conditional  tables  ("if  tables")  are  a different syntax to specify
-       field assignments that will be applied only to CSV records which  match
-       certain patterns.
-
-       MATCHER  could  be  either field or record matcher, as described above.
-       When MATCHER matches, values from that row would be assigned to the CSV
-       fields named on the if line, in the same order.
-
-       Therefore if table is exactly equivalent to a sequence of of if blocks:
-
-              if MATCHER1
-                CSVFIELDNAME1 VALUE11
-                CSVFIELDNAME2 VALUE12
-                ...
-                CSVFIELDNAMEn VALUE1n
-
-              if MATCHER2
-                CSVFIELDNAME1 VALUE21
-                CSVFIELDNAME2 VALUE22
-                ...
-                CSVFIELDNAMEn VALUE2n
-
-              if MATCHER3
-                CSVFIELDNAME1 VALUE31
-                CSVFIELDNAME2 VALUE32
-                ...
-                CSVFIELDNAMEn VALUE3n
-
-       Each line starting with MATCHER should contain enough (possibly  empty)
-       values for all the listed fields.
-
-       Rules  would be checked and applied in the order they are listed in the
-       table and, like with if blocks, later rules (in the same or another ta-
-       ble) or if blocks could override the effect of any rule.
-
-       Instead  of ',' you can use a variety of other non-alphanumeric charac-
-       ters as a separator.  First character after if is taken to be the sepa-
-       rator  for the rest of the table.  It is the responsibility of the user
-       to ensure that separator does not occur inside MATCHERs  and  values  -
-       there is no way to escape separator.
-
-       Example:
-
-              if,account2,comment
-              atm transaction fee,expenses:business:banking,deductible? check it
-              %description groceries,expenses:groceries,
-              2020/01/12.*Plumbing LLC,expenses:house:upkeep,emergency plumbing call-out
-
-   end
-       This  rule  can  be  used inside if blocks (only), to make hledger stop
-       reading this CSV file and move on to the next input file, or to command
-       execution.  Eg:
-
-              # ignore everything following the first empty record
-              if ,,,,
-               end
-
-   date-format
-              date-format DATEFMT
-
-       This  is  a  helper for the date (and date2) fields.  If your CSV dates
-       are not formatted like YYYY-MM-DD,  YYYY/MM/DD  or  YYYY.MM.DD,  you'll
-       need  to  add  a  date-format rule describing them with a strptime date
-       parsing pattern, which must parse the CSV date value completely.   Some
-       examples:
-
-              # MM/DD/YY
-              date-format %m/%d/%y
-
-              # D/M/YYYY
-              # The - makes leading zeros optional.
-              date-format %-d/%-m/%Y
-
-              # YYYY-Mmm-DD
-              date-format %Y-%h-%d
-
-              # M/D/YYYY HH:MM AM some other junk
-              # Note the time and junk must be fully parsed, though only the date is used.
-              date-format %-m/%-d/%Y %l:%M %p some other junk
-
-       For the supported strptime syntax, see:
-       https://hackage.haskell.org/package/time/docs/Data-Time-For-
-       mat.html#v:formatTime
-
-       Note that although you can parse date-times which include a time  zone,
-       that  time zone is ignored; it will not change the date that is parsed.
-       This means when reading CSV data with times  not  in  your  local  time
-       zone, dates can be "off by one".
-
-   decimal-mark
-              decimal-mark .
-
-       or:
-
-              decimal-mark ,
-
-       hledger  automatically accepts either period or comma as a decimal mark
-       when parsing numbers (cf Amounts).  However if any numbers in  the  CSV
-       contain  digit  group  marks,  such  as thousand-separating commas, you
-       should declare the decimal mark explicitly with  this  rule,  to  avoid
-       misparsed numbers.
-
-   newest-first
-       hledger  always sorts the generated transactions by date.  Transactions
-       on the same date should appear in the same order as their CSV  records,
-       as  hledger  can  usually auto-detect whether the CSV's normal order is
-       oldest first or newest first.  But if all of the following are true:
-
-       o the CSV might sometimes contain just one day  of  data  (all  records
-         having the same date)
-
-       o the  CSV  records are normally in reverse chronological order (newest
-         at the top)
-
-       o and you care about preserving the order of same-day transactions
-
-       then, you should add the newest-first rule as a hint.  Eg:
-
-              # tell hledger explicitly that the CSV is normally newest first
-              newest-first
-
-   include
-              include RULESFILE
-
-       This includes the contents of another CSV rules  file  at  this  point.
-       RULESFILE  is  an  absolute file path or a path relative to the current
-       file's directory.  This can be useful for sharing common rules  between
-       several rules files, eg:
-
-              # someaccount.csv.rules
-
-              ## someaccount-specific rules
-              fields   date,description,amount
-              account1 assets:someaccount
-              account2 expenses:misc
-
-              ## common rules
-              include categorisation.rules
-
-   balance-type
-       Balance assertions generated by assigning to balanceN are of the simple
-       = type by default, which is  a  single-commodity,  subaccount-excluding
-       assertion.  You may find the subaccount-including variants more useful,
-       eg if you have created some virtual subaccounts  of  checking  to  help
-       with  budgeting.  You can select a different type of assertion with the
-       balance-type rule:
-
-              # balance assertions will consider all commodities and all subaccounts
-              balance-type ==*
-
-       Here are the balance assertion types for quick reference:
-
-              =    single commodity, exclude subaccounts
-              =*   single commodity, include subaccounts
-              ==   multi commodity,  exclude subaccounts
-              ==*  multi commodity,  include subaccounts
-
-   Tips
-   Rapid feedback
-       It's a good idea to get rapid feedback  while  creating/troubleshooting
-       CSV rules.  Here's a good way, using entr from http://eradman.com/entr-
-       project :
-
-              $ ls foo.csv* | entr bash -c 'echo ----; hledger -f foo.csv print desc:SOMEDESC'
-
-       A desc: query (eg) is used to select just one, or a  few,  transactions
-       of  interest.   "bash  -c"  is used to run multiple commands, so we can
-       echo a separator each time the command re-runs,  making  it  easier  to
-       read the output.
-
-   Valid CSV
-       hledger  accepts  CSV  conforming  to  RFC  4180.   When CSV values are
-       enclosed in quotes, note:
-
-       o they must be double quotes (not single quotes)
-
-       o spaces outside the quotes are not allowed
-
-   File Extension
-       To help hledger identify the format and show the right error  messages,
-       CSV/SSV/TSV  files  should  normally be named with a .csv, .ssv or .tsv
-       filename extension.  Or, the file path should be  prefixed  with  csv:,
-       ssv: or tsv:.  Eg:
-
-              $ hledger -f foo.ssv print
-
-       or:
-
-              $ cat foo | hledger -f ssv:- foo
-
-       You  can  override  the file extension with a separator rule if needed.
-       See also: Input files in the hledger manual.
-
-   Reading multiple CSV files
-       If you use multiple -f options to read  multiple  CSV  files  at  once,
-       hledger  will  look for a correspondingly-named rules file for each CSV
-       file.  But if you use the --rules-file option, that rules file will  be
-       used for all the CSV files.
-
-   Valid transactions
-       After reading a CSV file, hledger post-processes and validates the gen-
-       erated journal entries as it would for a journal file - balancing them,
-       applying  balance  assignments,  and canonicalising amount styles.  Any
-       errors at this stage will be reported in the usual way, displaying  the
-       problem entry.
-
-       There is one exception: balance assertions, if you have generated them,
-       will not be checked, since normally these will work only when  the  CSV
-       data  is  part  of  the  main journal.  If you do need to check balance
-       assertions generated from CSV right away, pipe into another hledger:
-
-              $ hledger -f file.csv print | hledger -f- print
-
-   Deduplicating, importing
-       When you download a CSV file periodically, eg to get your  latest  bank
-       transactions,  the  new  file  may overlap with the old one, containing
-       some of the same records.
-
-       The import command will (a) detect the new transactions, and (b) append
-       just those transactions to your main journal.  It is idempotent, so you
-       don't have to remember how many times you ran it or with which  version
-       of  the  CSV.  (It keeps state in a hidden .latest.FILE.csv file.) This
-       is the easiest way to import CSV data.  Eg:
-
-              # download the latest CSV files, then run this command.
-              # Note, no -f flags needed here.
-              $ hledger import *.csv [--dry]
-
-       This method works for most CSV files.  (Where  records  have  a  stable
-       chronological order, and new records appear only at the new end.)
-
-       A  number of other tools and workflows, hledger-specific and otherwise,
-       exist for converting, deduplicating, classifying and managing CSV data.
-       See:

-
-   Setting amounts
-       Some tips on using the amount-setting rules discussed above.
-
-       Here are the ways to set a posting's amount:
-
-       1. If the CSV has a single amount field:
-       Assign (via a fields list or a field assignment) to amountN.  This sets
-       the Nth posting's amount.  N is usually 1 or 2 but can go up to 99.
-
-       2. If the CSV has separate amount fields for debit & credit (in & out):
-
-           a. If both fields are unsigned:
-           Assign to amountN-in and amountN-out.  This sets posting N's amount
-           to whichever of these has a non-zero value, and negates the  "-out"
-           value.
-
-           b. If either field is signed (can contain a minus sign):
-           Use  a  conditional  rule  to  flip the sign (of non-empty values).
-           Since hledger always negates amountN-out, if it was  already  nega-
-           tive,  we  must  undo  that  by negating once more (but only if the
-           field is non-empty):
-
-                  fields date, description, amount1-in, amount1-out
-                  if %amount1-out [1-9]
-                   amount1-out -%amount1-out
-
-           c. If both fields, or neither field, can contain a non-zero value:
-           hledger normally expects exactly one of the fields to have  a  non-
-           zero  value.   Eg,  the  amountN-in/amountN-out  rules would reject
-           value pairs like these:
-
-                  "",  ""
-                  "0", "0"
-                  "1", "none"
-
-           So, use smarter conditional rules to set the amount from the appro-
-           priate  field.   Eg,  these  rules would make it use only the value
-           containing non-zero digits, handling the above:
-
-                  fields date, description, in, out
-                  if %in [1-9]
-                   amount1 %in
-                  if %out [1-9]
-                   amount1 %out
-
-       3. If you are stuck with hledger <1.17, or you want posting 2's  amount
-          converted to cost:
-       Assign to amount (or to amount-in and amount-out).  (The old numberless
-       syntax, which sets amount1 and amount2.)
-
-       4. If the CSV has the balance instead of the transaction amount:
-       Assign to balanceN, which sets posting N's amount indirectly via a bal-
-       ance assignment.  (Old syntax: balance, equivalent to balance1.)
-
-           o If hledger guesses the wrong default account name:
-           When  setting  the  amount via balance assertion, hledger may guess
-           the wrong default account name.  So, set the account  name  explic-
-           itly, eg:
-
-                    fields date, description, balance1
-                    account1 assets:checking
-
-   Amount signs
-       There  is  some  special handling for amount signs, to simplify parsing
-       and sign-flipping:
-
-       o If an amount value begins with a plus sign:
-       that will be removed: +AMT becomes AMT
-
-       o If an amount value is parenthesised:
-       it will be de-parenthesised and sign-flipped: (AMT) becomes -AMT
-
-       o If an amount value has two minus signs (or two sets  of  parentheses,
-         or a minus sign and parentheses):
-       they cancel out and will be removed: --AMT or -(AMT) becomes AMT
-
-       o If  an  amount value contains just a sign (or just a set of parenthe-
-         ses):
-       that is removed, making it an empty value.  "+" or "-" or "()"  becomes
-       "".
-
-   Setting currency/commodity
-       If  the  currency/commodity  symbol  is  included  in  the CSV's amount
-       field(s):
-
-              2020-01-01,foo,$123.00
-
-       you don't have to do anything special for the commodity symbol, it will
-       be assigned as part of the amount.  Eg:
-
-              fields date,description,amount
-
-              2020-01-01 foo
-                  expenses:unknown         $123.00
-                  income:unknown          $-123.00
-
-       If the currency is provided as a separate CSV field:
-
-              2020-01-01,foo,USD,123.00
-
-       You can assign that to the currency pseudo-field, which has the special
-       effect of prepending itself to every amount in the transaction (on  the
-       left, with no separating space):
-
-              fields date,description,currency,amount
-
-              2020-01-01 foo
-                  expenses:unknown       USD123.00
-                  income:unknown        USD-123.00
-
-       Or,  you  can  use a field assignment to construct the amount yourself,
-       with more control.  Eg to put the symbol on the right, and separated by
-       a space:
-
-              fields date,description,cur,amt
-              amount %amt %cur
-
-              2020-01-01 foo
-                  expenses:unknown        123.00 USD
-                  income:unknown         -123.00 USD
-
-       Note  we  used a temporary field name (cur) that is not currency - that
-       would trigger the prepending effect, which we don't want here.
-
-   Amount decimal places
-       Like amounts in a journal file, the amounts generated by CSV rules like
-       amount1 influence commodity display styles, such as the number of deci-
-       mal places displayed in reports.
-
-       The original amounts as written in the CSV file do not  affect  display
-       style (because we don't yet reliably know their commodity).
-
-   Referencing other fields
-       In  field assignments, you can interpolate only CSV fields, not hledger
-       fields.  In the example below, there's both a CSV field and  a  hledger
-       field  named  amount1, but %amount1 always means the CSV field, not the
-       hledger field:
-
-              # Name the third CSV field "amount1"
-              fields date,description,amount1
-
-              # Set hledger's amount1 to the CSV amount1 field followed by USD
-              amount1 %amount1 USD
-
-              # Set comment to the CSV amount1 (not the amount1 assigned above)
-              comment %amount1
-
-       Here, since there's no CSV amount1 field, %amount1 will produce a  lit-
-       eral "amount1":
-
-              fields date,description,csvamount
-              amount1 %csvamount USD
-              # Can't interpolate amount1 here
-              comment %amount1
-
-       When  there  are  multiple field assignments to the same hledger field,
-       only the last one takes effect.  Here, comment's value will be be B, or
-       C if "something" is matched, but never A:
-
-              comment A
-              comment B
-              if something
-               comment C
-
-   How CSV rules are evaluated
-       Here's  how  to  think of CSV rules being evaluated (if you really need
-       to).  First,
-
-       o include - all includes are inlined, from top to bottom, depth  first.
-         (At  each  include  point the file is inlined and scanned for further
-         includes, recursively, before proceeding.)
-
-       Then "global" rules are  evaluated,  top  to  bottom.   If  a  rule  is
-       repeated, the last one wins:
-
-       o skip (at top level)
-
-       o date-format
-
-       o newest-first
-
-       o fields - names the CSV fields, optionally sets up initial assignments
-         to hledger fields
-
-       Then for each CSV record in turn:
-
-       o test all if blocks.  If any of them contain  a  end  rule,  skip  all
-         remaining CSV records.  Otherwise if any of them contain a skip rule,
-         skip that many CSV records.   If  there  are  multiple  matched  skip
-         rules, the first one wins.
-
-       o collect  all field assignments at top level and in matched if blocks.
-         When there are multiple assignments for a field, keep only  the  last
-         one.
-
-       o compute  a  value  for  each  hledger field - either the one that was
-         assigned to it (and interpolate the %CSVFIELDNAME references),  or  a
-         default
-
-       o generate a synthetic hledger transaction from these values.
-
-       This  is all part of the CSV reader, one of several readers hledger can
-       use to parse input files.  When all files have been read  successfully,
-       the  transactions  are passed as input to whichever hledger command the
-       user specified.
-
-TIMECLOCK FORMAT
-       The time logging format of timeclock.el, as read by hledger.
-
-       hledger can read time logs in timeclock format.  As with Ledger,  these
-       are (a subset of) timeclock.el's format, containing clock-in and clock-
-       out entries as in the example below.  The date is a simple  date.   The
-       time  format is HH:MM[:SS][+-ZZZZ].  Seconds and timezone are optional.
-       The timezone, if present, must be four digits and is ignored (currently
-       the time is always interpreted as a local time).
-
-              i 2015/03/30 09:00:00 some:account name  optional description after two spaces
-              o 2015/03/30 09:20:00
-              i 2015/03/31 22:21:45 another account
-              o 2015/04/01 02:00:34
-
-       hledger  treats  each  clock-in/clock-out pair as a transaction posting
-       some number of hours to an account.  Or if the session spans more  than
-       one  day, it is split into several transactions, one for each day.  For
-       the above time log, hledger print generates these journal entries:
-
-              $ hledger -f t.timeclock print
-              2015-03-30 * optional description after two spaces
-                  (some:account name)         0.33h
-
-              2015-03-31 * 22:21-23:59
-                  (another account)         1.64h
-
-              2015-04-01 * 00:00-02:00
-                  (another account)         2.01h
-
-       Here is a sample.timeclock to download and some queries to try:
-
-              $ hledger -f sample.timeclock balance                               # current time balances
-              $ hledger -f sample.timeclock register -p 2009/3                    # sessions in march 2009
-              $ hledger -f sample.timeclock register -p weekly --depth 1 --empty  # time summary by week
-
-       To generate time logs, ie to clock in and clock out, you could:
-
-       o use emacs and the built-in timeclock.el, or the  extended  timeclock-
-         x.el and perhaps the extras in ledgerutils.el
-
-       o at the command line, use these bash aliases: shell     alias ti="echo
-         i `date '+%Y-%m-%d %H:%M:%S'` \$* >>$TIMELOG"      alias  to="echo  o
-         `date '+%Y-%m-%d %H:%M:%S'` >>$TIMELOG"
-
-       o or use the old ti and to scripts in the ledger 2.x repository.  These
-         rely on a "timeclock" executable which I think is just the  ledger  2
-         executable renamed.
-
-TIMEDOT FORMAT
-       hledger's human-friendly time logging format.
-
-       Timedot  is  a plain text format for logging dated, categorised quanti-
-       ties (of time, usually), supported by hledger.  It  is  convenient  for
-       approximate  and retroactive time logging, eg when the real-time clock-
-       in/out required with a timeclock file is too precise or  too  interrup-
-       tive.   It  can be formatted like a bar chart, making clear at a glance
-       where time was spent.
-
-       Though called "timedot", this format is read by hledger  as  commodity-
-       less  quantities,  so  it  could  be used to represent dated quantities
-       other than time.  In the docs below we'll assume it's time.
-
-       A timedot file contains a series of day entries.  A  day  entry  begins
-       with  a  non-indented hledger-style simple date (Y-M-D, Y/M/D, Y.M.D..)
-       Any additional text on the same line is used as a transaction  descrip-
-       tion for this day.
-
-       This is followed by optionally-indented timelog items for that day, one
-       per   line.    Each   timelog   item   is    a    note,    usually    a
-       hledger:style:account:name  representing  a  time category, followed by
-       two or more spaces, and a quantity.   Each  timelog  item  generates  a
-       hledger transaction.
-
-       Quantities can be written as:
-
-       o dots:  a sequence of dots (.) representing quarter hours.  Spaces may
-         optionally be used for grouping.  Eg: ....  ..
-
-       o an integral or decimal number, representing hours.  Eg: 1.5
-
-       o an integral or decimal number immediately followed by a  unit  symbol
-         s,  m,  h, d, w, mo, or y, representing seconds, minutes, hours, days
-         weeks, months or years respectively.  Eg: 90m.  The following equiva-
-         lencies  are  assumed,  currently: 1m = 60s, 1h = 60m, 1d = 24h, 1w =
-         7d, 1mo = 30d, 1y=365d.
-
-       There is some flexibility allowing notes and  todo  lists  to  be  kept
-       right in the time log, if needed:
-
-       o Blank lines and lines beginning with # or ; are ignored.
-
-       o Lines not ending with a double-space and quantity are parsed as items
-         taking no time, which will not appear in balance reports by  default.
-         (Add -E to see them.)
-
-       o Org  mode headlines (lines beginning with one or more * followed by a
-         space) can be used as date lines or  timelog  items  (the  stars  are

-         tion, faster navigation, controlling visibility etc.

-   Constructing command lines
-       hledger  has  an  extensive  and  powerful  command line interface.  We
-       strive to keep it simple and ergonomic, but you may run into one of the
-       confusing real world details described in OPTIONS, below.  If that hap-
-       pens, here are some tips that may help:
-
-       o command-specific options must go after the command (it's fine to  put
-         all options there) (hledger CMD OPTS ARGS)
-
-       o running  add-on  executables directly simplifies command line parsing
-         (hledger-ui OPTS ARGS)
-
-       o enclose "problematic" args in single quotes
-
-       o if needed, also add a backslash to hide regular expression  metachar-
-         acters from the shell
-
-       o to see how a misbehaving command is being parsed, add --debug=2.
-
-   Starting a journal file
-       hledger   looks   for   your   accounting   data  in  a  journal  file,
-       $HOME/.hledger.journal by default:
-
-              $ hledger stats
-              The hledger journal file "/Users/simon/.hledger.journal" was not found.
-              Please create it first, eg with "hledger add" or a text editor.
-              Or, specify an existing journal file with -f or LEDGER_FILE.
-
-       You can override this by setting the LEDGER_FILE environment  variable.
-       It's a good practice to keep this important file under version control,
-       and to start a new file each year.  So  you  could  do  something  like
-       this:
-
-              $ mkdir ~/finance
-              $ cd ~/finance
-              $ git init
-              Initialized empty Git repository in /Users/simon/finance/.git/
-              $ touch 2020.journal
-              $ echo "export LEDGER_FILE=$HOME/finance/2020.journal" >> ~/.bashrc
-              $ source ~/.bashrc
-              $ hledger stats
-              Main file                : /Users/simon/finance/2020.journal
-              Included files           :
-              Transactions span        :  to  (0 days)
-              Last transaction         : none
-              Transactions             : 0 (0.0 per day)
-              Transactions last 30 days: 0 (0.0 per day)
-              Transactions last 7 days : 0 (0.0 per day)
-              Payees/descriptions      : 0
-              Accounts                 : 0 (depth 0)
-              Commodities              : 0 ()
-              Market prices            : 0 ()
-
-   Setting opening balances
-       Pick  a  starting  date  for which you can look up the balances of some
-       real-world assets (bank accounts,  wallet..)  and  liabilities  (credit
-       cards..).
-
-       To  avoid  a  lot of data entry, you may want to start with just one or
-       two accounts, like your checking account or cash  wallet;  and  pick  a
-       recent  starting  date,  like  today or the start of the week.  You can
-       always come back later and add more accounts and older transactions, eg
-       going back to january 1st.
-
-       Add  an opening balances transaction to the journal, declaring the bal-
-       ances on this date.  Here are two ways to do it:
-
-       o The first way: open the journal in any text editor and save an  entry
-         like this:
-
-                2020-01-01 * opening balances
-                    assets:bank:checking                $1000   = $1000
-                    assets:bank:savings                 $2000   = $2000
-                    assets:cash                          $100   = $100
-                    liabilities:creditcard               $-50   = $-50
-                    equity:opening/closing balances
-
-         These  are  start-of-day  balances, ie whatever was in the account at
-         the end of the previous day.
-
-         The * after the date is an  optional  status  flag.   Here  it  means
-         "cleared & confirmed".
-
-         The  currency symbols are optional, but usually a good idea as you'll
-         be dealing with multiple currencies sooner or later.
-
-         The = amounts are optional balance assertions, providing extra  error
-         checking.
-
-       o The  second  way:  run hledger add and follow the prompts to record a
-         similar transaction:
-
-                $ hledger add
-                Adding transactions to journal file /Users/simon/finance/2020.journal
-                Any command line arguments will be used as defaults.
-                Use tab key to complete, readline keys to edit, enter to accept defaults.
-                An optional (CODE) may follow transaction dates.
-                An optional ; COMMENT may follow descriptions or amounts.
-                If you make a mistake, enter < at any prompt to go one step backward.
-                To end a transaction, enter . when prompted.
-                To quit, enter . at a date prompt or press control-d or control-c.
-                Date [2020-02-07]: 2020-01-01
-                Description: * opening balances
-                Account 1: assets:bank:checking
-                Amount  1: $1000
-                Account 2: assets:bank:savings
-                Amount  2 [$-1000]: $2000
-                Account 3: assets:cash
-                Amount  3 [$-3000]: $100
-                Account 4: liabilities:creditcard
-                Amount  4 [$-3100]: $-50
-                Account 5: equity:opening/closing balances
-                Amount  5 [$-3050]:
-                Account 6 (or . or enter to finish this transaction): .
-                2020-01-01 * opening balances
-                    assets:bank:checking                      $1000
-                    assets:bank:savings                       $2000
-                    assets:cash                                $100
-                    liabilities:creditcard                     $-50
-                    equity:opening/closing balances          $-3050
-
-                Save this transaction to the journal ? [y]:
-                Saved.
-                Starting the next transaction (. or ctrl-D/ctrl-C to quit)
-                Date [2020-01-01]: .
-
-       If you're using version control, this could be a good  time  to  commit
-       the journal.  Eg:
-
-              $ git commit -m 'initial balances' 2020.journal
-
-   Recording transactions
-       As  you spend or receive money, you can record these transactions using
-       one of the methods above (text editor, hledger add)  or  by  using  the
-       hledger-iadd  or hledger-web add-ons, or by using the import command to
-       convert CSV data downloaded from your bank.
-
-       Here are some simple transactions, see  the  hledger_journal(5)  manual
-       and hledger.org for more ideas:
-
-              2020/1/10 * gift received
-                assets:cash   $20
-                income:gifts
-
-              2020.1.12 * farmers market
-                expenses:food    $13
-                assets:cash
-
-              2020-01-15 paycheck
-                income:salary
-                assets:bank:checking    $1000
-
-   Reconciling
-       Periodically  you should reconcile - compare your hledger-reported bal-
-       ances against external sources of truth, like bank statements  or  your
-       bank's  website - to be sure that your ledger accurately represents the
-       real-world balances (and, that the  real-world  institutions  have  not
-       made  a  mistake!).   This gets easy and fast with (1) practice and (2)
-       frequency.  If you do it daily, it can take 2-10 minutes.  If  you  let
-       it  pile  up, expect it to take longer as you hunt down errors and dis-
-       crepancies.
-
-       A typical workflow:
-
-       1. Reconcile cash.  Count what's in your  wallet.   Compare  with  what
-          hledger  reports  (hledger bal cash).  If they are different, try to
-          remember the missing transaction, or  look  for  the  error  in  the
-          already-recorded  transactions.   A  register  report can be helpful
-          (hledger reg cash).  If you can't find the error, add an  adjustment
-          transaction.  Eg if you have $105 after the above, and can't explain
-          the missing $2, it could be:
-
-                  2020-01-16 * adjust cash
-                      assets:cash    $-2 = $105
-                      expenses:misc
-
-       2. Reconcile checking.  Log in to your bank's website.  Compare today's
-          (cleared) balance with hledger's cleared balance (hledger bal check-
-          ing -C).  If they are different, track down the error or record  the
-          missing  transaction(s) or add an adjustment transaction, similar to
-          the above.  Unlike the cash case, you can usually compare the trans-
-          action  history  and  running  balance  from  your bank with the one
-          reported by hledger reg checking -C.  This will  be  easier  if  you
-          generally  record  transaction  dates  quite  similar to your bank's
-          clearing dates.
-
-       3. Repeat for other asset/liability accounts.
-
-       Tip: instead of the register command, use hledger-ui  to  see  a  live-
-       updating register while you edit the journal: hledger-ui --watch --reg-
-       ister checking -C
-
-       After reconciling, it could be a  good  time  to  mark  the  reconciled
-       transactions'  status  as "cleared and confirmed", if you want to track
-       that, by adding the * marker.  Eg in the  paycheck  transaction  above,
-       insert * between 2020-01-15 and paycheck
-
-       If  you're using version control, this can be another good time to com-
-       mit:
-
-              $ git commit -m 'txns' 2020.journal

-
-   Migrating to a new file
-       At  the end of the year, you may want to continue your journal in a new
-       file, so that old transactions don't slow down or clutter your reports,
-       and  to  help ensure the integrity of your accounting history.  See the
-       close command.
-
-       If using version control, don't forget to git add the new file.
-
-LIMITATIONS
-       The need to precede add-on command options with --  when  invoked  from
-       hledger is awkward.
-
-       When input data contains non-ascii characters, a suitable system locale
-       must be configured (or there will be an unhelpful error).  Eg on POSIX,
-       set LANG to something other than C.
-
-       In a Microsoft Windows CMD window, non-ascii characters and colours are
-       not supported.
-
-       On Windows, non-ascii characters may not display correctly when running
-       a hledger built in CMD in MSYS/CYGWIN, or vice-versa.
-
-       In a Cygwin/MSYS/Mintty window, the tab key is not supported in hledger
-       add.
-
-       Not all of Ledger's journal file syntax is supported.  See file  format
-       differences.
-
-       On  large  data  files,  hledger  is  slower  and uses more memory than
-       Ledger.
-
-TROUBLESHOOTING
-       Here are some issues you might encounter  when  you  run  hledger  (and
-       remember  you can also seek help from the IRC channel, mail list or bug
-       tracker):
-
-       Successfully installed, but "No command 'hledger' found"
-       stack and cabal install binaries into a special directory, which should
-       be  added  to your PATH environment variable.  Eg on unix-like systems,
-       that is ~/.local/bin and ~/.cabal/bin respectively.
-
-       I set a custom LEDGER_FILE, but hledger is still using the default file
-       LEDGER_FILE  should  be  a  real environment variable, not just a shell
-       variable.  The command env | grep LEDGER_FILE should show it.  You  may
-       need to use export.  Here's an explanation.
-
-       Getting  errors  like "Illegal byte sequence" or "Invalid or incomplete
-       multibyte or wide character" or "commitAndReleaseBuffer: invalid  argu-
-       ment (invalid character)"
-       Programs compiled with GHC (hledger, haskell build tools, etc.) need to
-       have a UTF-8-aware locale configured in the environment, otherwise they
-       will  fail  with  these  kinds  of errors when they encounter non-ascii
-       characters.
-
-       To fix it, set the LANG environment variable to some locale which  sup-
-       ports UTF-8.  The locale you choose must be installed on your system.
-
-       Here's an example of setting LANG temporarily, on Ubuntu GNU/Linux:
-
-              $ file my.journal
-              my.journal: UTF-8 Unicode text         # the file is UTF8-encoded
-              $ echo $LANG
-              C                                      # LANG is set to the default locale, which does not support UTF8
-              $ locale -a                            # which locales are installed ?
-              C
-              en_US.utf8                             # here's a UTF8-aware one we can use
-              POSIX
-              $ LANG=en_US.utf8 hledger -f my.journal print   # ensure it is used for this command
-
-       If  available,  C.UTF-8 will also work.  If your preferred locale isn't
-       listed  by  locale  -a,  you  might  need  to  install   it.    Eg   on
-       Ubuntu/Debian:
-
-              $ apt-get install language-pack-fr
-              $ locale -a
-              C
-              en_US.utf8
-              fr_BE.utf8
-              fr_CA.utf8
-              fr_CH.utf8
-              fr_FR.utf8
-              fr_LU.utf8
-              POSIX
-              $ LANG=fr_FR.utf8 hledger -f my.journal print
-
-       Here's how you could set it permanently, if you use a bash shell:
-
-              $ echo "export LANG=en_US.utf8" >>~/.bash_profile
-              $ bash --login
-
-       Exact  spelling  and capitalisation may be important.  Note the differ-
-       ence on MacOS (UTF-8, not utf8).   Some  platforms  (eg  ubuntu)  allow
-       variant spellings, but others (eg macos) require it to be exact:
-
-              $ locale -a | grep -iE en_us.*utf
-              en_US.UTF-8
-              $ LANG=en_US.UTF-8 hledger -f my.journal print

-hledger-1.22.1                    August 2021                       HLEDGER(1)
+       manual is for hledger 1.22.2.
+
+SYNOPSIS
+       hledger
+
+       hledger [-f FILE] COMMAND [OPTIONS] [ARGS]
+
+       hledger [-f FILE] ADDONCMD -- [OPTIONS] [ARGS]
+
+DESCRIPTION
+       hledger  is  a  reliable,  cross-platform  set of programs for tracking
+       money, time, or any other commodity, using double-entry accounting  and
+       a  simple,  editable  file  format.  hledger is inspired by and largely
+       compatible with ledger(1).
+
+       The basic function of the hledger CLI is to  read  a  plain  text  file
+       describing financial transactions (in accounting terms, a general jour-
+       nal) and print useful reports on standard output,  or  export  them  as
+       CSV.   hledger can also read some other file formats such as CSV files,
+       translating them to journal format.  Additionally, hledger lists  other
+       hledger-*  executables found in the user's $PATH and can invoke them as
+       subcommands.
+
+       hledger reads data from one or more files  in  hledger  journal,  time-
+       clock,  timedot,  or  CSV format specified with -f, or $LEDGER_FILE, or
+       $HOME/.hledger.journal          (on          windows,           perhaps
+       C:/Users/USER/.hledger.journal).  If using $LEDGER_FILE, note this must
+       be a real environment variable, not a shell variable.  You can  specify
+       standard input with -f-.
+
+       Transactions  are  dated movements of money between two (or more) named
+       accounts, and are recorded with journal entries like this:
+
+              2015/10/16 bought food
+               expenses:food          $10
+               assets:cash
+
+       Most users use a text editor to edit the journal, usually with an  edi-
+       tor mode such as ledger-mode for added convenience.  hledger's interac-
+       tive add command is another way to record  new  transactions.   hledger
+       never changes existing transactions.
+
+       To  get  started,  you  can  either save some entries like the above in
+       ~/.hledger.journal, or run hledger add and follow  the  prompts.   Then
+       try  some  commands like hledger print or hledger balance.  Run hledger
+       with no arguments for a list of commands.
+
+OPTIONS
+   General options
+       To see general usage help, including general  options  which  are  sup-
+       ported by most hledger commands, run hledger -h.

+              using period expressions syntax
+
+       --date2
+              match the secondary date instead (see  command  help  for  other
+              effects)
+
+       -U --unmarked
+              include only unmarked postings/txns (can combine with -P or -C)
+
+       -P --pending

+
+       -E --empty
+              show  items with zero amount, normally hidden (and vice-versa in
+              hledger-ui/hledger-web)
+
+       -B --cost
+              convert amounts to their cost/selling amount at transaction time
+
+       -V --market
+              convert  amounts to their market value in default valuation com-
+              modities
+
+       -X --exchange=COMM
+              convert amounts to their market value in commodity COMM
+
+       --value
+              convert amounts to cost or  market  value,  more  flexibly  than
+              -B/-V/-X
+
+       --infer-market-prices
+              use  transaction  prices  (recorded  with @ or @@) as additional
+              market prices, as if they were P directives
+
+       --auto apply automated posting rules to modify transactions.
+
+       --forecast
+              generate future transactions from  periodic  transaction  rules,
+              for  the  next 6 months or till report end date.  In hledger-ui,
+              also make ordinary future transactions visible.
+
+       --color=WHEN (or --colour=WHEN)
+              Should color-supporting commands use ANSI color  codes  in  text
+              output.   'auto' (default): whenever stdout seems to be a color-
+              supporting terminal.  'always' or 'yes': always, useful eg  when
+              piping  output  into  'less  -R'.   'never'  or  'no': never.  A
+              NO_COLOR environment variable overrides this.
+
+       When a reporting option appears more than once in the command line, the
+       last one takes precedence.
+
+       Some reporting options can also be written as query arguments.
+
+   Command options
+       To  see  options  for  a particular command, including command-specific
+       options, run: hledger COMMAND -h.
+
+       Command-specific options must be written after the  command  name,  eg:
+       hledger print -x.
+
+       Additionally,  if  the  command  is  an add-on, you may need to put its
+       options after a double-hyphen, eg: hledger ui -- --watch.  Or, you  can
+       run the add-on executable directly: hledger-ui --watch.

+       Most  hledger  commands  accept arguments after the command name, which
+       are often a query, filtering the data in some way.
+
+       You can save a set of command line options/arguments  in  a  file,  and
+       then  reuse  them by writing @FILENAME as a command line argument.  Eg:
+       hledger bal @foo.args.  (To prevent this, eg if you  have  an  argument
+       that  begins  with  a literal @, precede it with --, eg: hledger bal --
+       @ARG).
+
+       Inside the argument file, each line should contain just one  option  or
+       argument.  Avoid the use of spaces, except inside quotes (or you'll see
+       a confusing error).  Between a flag and its argument, use =  (or  noth-
+       ing).  Bad:
+
+              assets depth:2
+              -X USD
+
+       Good:
+
+              assets
+              depth:2
+              -X=USD
+
+       For  special characters (see below), use one less level of quoting than
+       you would at the command prompt.  Bad:
+
+              -X"$"
+
+       Good:
+
+              -X$
+
+       See also: Save frequently used options.
+
+   Special characters
+   Single escaping (shell metacharacters)
+       In shell command lines, characters significant to your shell - such  as
+       spaces,  <, >, (, ), |, $ and \ - should be "shell-escaped" if you want
+       hledger to see them.  This is done by enclosing them in single or  dou-
+       ble  quotes,  or  by  writing  a backslash before them.  Eg to match an
+       account name containing a space:
+
+              $ hledger register 'credit card'
+
+       or:
+
+              $ hledger register credit\ card
+
+       Windows users should keep in mind that cmd treats  single  quote  as  a
+       regular  character,  so  you should be using double quotes exclusively.
+       PowerShell treats both single and double quotes as quotes.
+
+   Double escaping (regular expression metacharacters)
+       Characters significant in regular expressions (described below) -  such
+       as  .,  ^,  $, [, ], (, ), |, and \ - may need to be "regex-escaped" if
+       you don't want them to be interpreted by hledger's  regular  expression
+       engine.   This  is  done  by writing backslashes before them, but since
+       backslash is typically also a shell metacharacter, both  shell-escaping
+       and  regex-escaping will be needed.  Eg to match a literal $ sign while
+       using the bash shell:
+
+              $ hledger balance cur:'\$'
+
+       or:
+
+              $ hledger balance cur:\\$
+
+   Triple escaping (for add-on commands)
+       When you use hledger to  run  an  external  add-on  command  (described
+       below),  one  level of shell-escaping is lost from any options or argu-
+       ments intended for by the add-on command, so those need an extra  level
+       of  shell-escaping.   Eg to match a literal $ sign while using the bash
+       shell and running an add-on command (ui):
+
+              $ hledger ui cur:'\\$'
+
+       or:
+
+              $ hledger ui cur:\\\\$
+
+       If you wondered why four backslashes, perhaps this helps:
+
+
+       unescaped:        $
+       escaped:          \$
+       double-escaped:   \\$
+       triple-escaped:   \\\\$
+
+       Or, you can avoid the extra escaping by running the  add-on  executable
+       directly:
+
+              $ hledger-ui cur:\\$
+
+   Less escaping
+       Options and arguments are sometimes used in places other than the shell
+       command line, where shell-escaping is not needed, so there  you  should
+       use one less level of escaping.  Those places include:
+
+       o an @argumentfile
+
+       o hledger-ui's filter field
+
+       o hledger-web's search form
+
+       o GHCI's prompt (used by developers).
+
+   Unicode characters
+       hledger is expected to handle non-ascii characters correctly:
+
+       o they  should  be  parsed  correctly in input files and on the command
+         line, by all hledger tools (add, iadd, hledger-web's  search/add/edit
+         forms, etc.)
+
+       o they  should  be  displayed  correctly  by all hledger tools, and on-
+         screen alignment should be preserved.
+
+       This requires a well-configured environment.  Here are some tips:
+
+       o A system locale must be configured, and  it  must  be  one  that  can
+         decode the characters being used.  In bash, you can set a locale like
+         this: export LANG=en_US.UTF-8.  There are some more details in  Trou-
+         bleshooting.   This step is essential - without it, hledger will quit
+         on encountering a non-ascii character (as with all GHC-compiled  pro-
+         grams).
+
+       o your  terminal  software  (eg  Terminal.app, iTerm, CMD.exe, xterm..)
+         must support unicode
+
+       o the terminal must be using a font which includes the required unicode
+         glyphs
+
+       o the  terminal should be configured to display wide characters as dou-
+         ble width (for report alignment)
+
+       o on Windows, for best results you should run hledger in the same  kind
+         of  environment in which it was built.  Eg hledger built in the stan-
+         dard CMD.EXE environment (like the binaries  on  our  download  page)
+         might  show  display  problems when run in a cygwin or msys terminal,
+         and vice versa.  (See eg #961).
+
+   Regular expressions
+       hledger uses regular expressions in a number of places:
+
+       o query terms, on the command line and in the hledger-web search  form:
+         REGEX, desc:REGEX, cur:REGEX, tag:...=REGEX
+
+       o CSV rules conditional blocks: if REGEX ...
+
+       o account  alias  directives  and options: alias /REGEX/ = REPLACEMENT,
+         --alias /REGEX/=REPLACEMENT
+
+       hledger's regular expressions come from  the  regex-tdfa  library.   If
+       they're  not doing what you expect, it's important to know exactly what
+       they support:
+
+       1. they are case insensitive
+
+       2. they are infix matching (they do not need to match the entire  thing
+          being matched)
+
+       3. they are POSIX ERE (extended regular expressions)
+
+       4. they also support GNU word boundaries (\b, \B, \<, \>)
+
+       5. they  do  not support backreferences; if you write \1, it will match
+          the digit 1.  Except when doing  text  replacement,  eg  in  account
+          aliases,  where backreferences can be used in the replacement string
+          to reference capturing groups in the search regexp.
+
+       6. they do not support mode modifiers ((?s)),  character  classes  (\w,
+          \d), or anything else not mentioned above.
+
+       Some things to note:
+
+       o In  the  alias directive and --alias option, regular expressions must
+         be enclosed in forward  slashes  (/REGEX/).   Elsewhere  in  hledger,
+         these are not required.
+
+       o In  queries,  to match a regular expression metacharacter like $ as a
+         literal character, prepend a backslash.  Eg  to  search  for  amounts
+         with the dollar sign in hledger-web, write cur:\$.
+
+       o On  the command line, some metacharacters like $ have a special mean-
+         ing to the shell and so must be escaped at least once more.  See Spe-
+         cial characters.
+
+ENVIRONMENT
+       LEDGER_FILE The journal file path when not specified with -f.  Default:
+       ~/.hledger.journal (on  windows,  perhaps  C:/Users/USER/.hledger.jour-
+       nal).
+
+       A  typical  value  is  ~/DIR/YYYY.journal,  where DIR is a version-con-
+       trolled finance directory and YYYY is the current year.  Or  ~/DIR/cur-
+       rent.journal, where current.journal is a symbolic link to YYYY.journal.
+
+       On Mac computers, you can set this and other environment variables in a
+       more  thorough  way that also affects applications started from the GUI
+       (say,  an  Emacs  dock  icon).   Eg  on  MacOS  Catalina   I   have   a
+       ~/.MacOSX/environment.plist file containing
+
+              {
+                "LEDGER_FILE" : "~/finance/current.journal"
+              }
+
+       To see the effect you may need to killall Dock, or reboot.
+
+       COLUMNS  The  screen  width used by the register command.  Default: the
+       full terminal width.
+
+       NO_COLOR If this variable exists with any value, hledger will  not  use
+       ANSI   color   codes   in   terminal   output.    This   overrides  the
+       --color/--colour option.
+
+DATA FILES
+       hledger reads transactions from one or more data  files.   The  default
+       data  file  is  $HOME/.hledger.journal  (or  on Windows, something like
+       C:/Users/USER/.hledger.journal).
+
+       You can override this with the $LEDGER_FILE environment variable:
+
+              $ setenv LEDGER_FILE ~/finance/2016.journal
+              $ hledger stats
+
+       or with one or more -f/--file options:
+
+              $ hledger -f /some/file -f another_file stats
+
+       The file name - means standard input:
+
+              $ cat some.journal | hledger -f-
+
+   Data formats
+       Usually the data file is in hledger's journal format, but it can be  in
+       any of the supported file formats, which currently are:
+
+
+       Reader:    Reads:                                    Used  for  file  exten-
+                                                            sions:
+       -----------------------------------------------------------------------------
+       journal    hledger journal files and  some  Ledger   .journal   .j  .hledger
+                  journals, for transactions                .ledger
+       time-      timeclock  files, for precise time log-   .timeclock
+       clock      ging
+       timedot    timedot  files,  for  approximate  time   .timedot
+                  logging
+       csv        comma/semicolon/tab/other-separated       .csv .ssv .tsv
+                  values, for data import
+
+       These formats are described in their own sections, below.
+
+       hledger detects the format automatically based on the  file  extensions
+       shown  above.   If  it  can't  recognise the file extension, it assumes
+       journal format.  So for non-journal files,  it's  important  to  use  a
+       recognised file extension, so as to either read successfully or to show
+       relevant error messages.
+
+       You can also force a specific reader/format by prefixing the file  path
+       with the format and a colon.  Eg, to read a .dat file as csv format:
+
+              $ hledger -f csv:/some/csv-file.dat stats
+
+       Or to read stdin (-) as timeclock format:
+
+              $ echo 'i 2009/13/1 08:00:00' | hledger print -ftimeclock:-
+
+   Multiple files
+       You  can specify multiple -f options, to read multiple files as one big
+       journal.  There are some limitations with this:
+
+       o most directives do not affect sibling files
+
+       o balance assertions will not see any account  balances  from  previous
+         files
+
+       If you need either of those things, you can
+
+       o use a single parent file which includes the others
+
+       o or  concatenate  the files into one before reading, eg: cat a.journal
+         b.journal | hledger -f- CMD.
+
+   Strict mode
+       hledger checks input files for valid data.  By default, the most impor-
+       tant  errors  are  detected,  while  still accepting easy journal files
+       without a lot of declarations:
+
+       o Are the input files parseable, with valid syntax ?
+
+       o Are all transactions balanced ?
+
+       o Do all balance assertions pass ?
+
+       With the -s/--strict flag, additional checks are performed:
+
+       o Are all accounts posted to, declared  with  an  account  directive  ?
+         (Account error checking)
+
+       o Are all commodities declared with a commodity directive ?  (Commodity
+         error checking)
+
+       o Are all commodity conversions declared explicitly ?
+
+       You can also use the check command to run  these  and  some  additional
+       checks.
+
+TIME PERIODS
+   Smart dates
+       hledger's user interfaces accept a flexible "smart date" syntax.  Smart
+       dates allow some english words, can be relative to  today's  date,  and
+       can have less-significant date parts omitted (defaulting to 1).
+
+       Examples:
+
+
+       2004/10/1,   2004-01-01,   exact date, several separators allowed.   Year
+       2004.9.1                   is 4+ digits, month is 1-12, day is 1-31
+       2004                       start of year
+       2004/10                    start of month
+       10/1                       month and day in current year
+       21                         day in current month
+       october, oct               start of month in current year
+       yesterday, today, tomor-   -1, 0, 1 days from today
+       row
+       last/this/next             -1, 0, 1 periods from the current period
+       day/week/month/quar-
+       ter/year
+       20181201                   8 digit YYYYMMDD with valid year month and day
+       201812                     6 digit YYYYMM with valid year and month
+
+       Counterexamples  -  malformed  digit  sequences  might  give surprising
+       results:
+
+
+       201813        6 digits with an  invalid  month  is  parsed  as  start  of
+                     6-digit year
+       20181301      8  digits  with  an  invalid  month  is  parsed as start of
+                     8-digit year
+       20181232      8 digits with an invalid day gives an error
+       201801012     9+ digits beginning with a valid YYYYMMDD gives an error
+
+
+   Report start & end date
+       By default, most hledger reports will show the full span of time repre-
+       sented by the journal data.  The report start date will be the earliest
+       transaction or posting date, and the report end date will be the latest
+       transaction, posting, or market price date.
+
+       Often  you  will  want  to see a shorter time span, such as the current
+       month.  You can specify a  start  and/or  end  date  using  -b/--begin,
+       -e/--end, -p/--period or a date: query (described below).  All of these
+       accept the smart date syntax.
+
+       Some notes:
+
+       o As in Ledger, end dates are exclusive, so you need to write the  date
+         after the last day you want to include.
+
+       o As  noted  in reporting options: among start/end dates specified with
+         options, the last (i.e.  right-most) option takes precedence.
+
+       o The effective report start and end dates are the intersection of  the
+         start/end  dates  from options and that from date: queries.  That is,
+         date:2019-01 date:2019 -p'2000 to  2030'  yields  January  2019,  the
+         smallest common time span.
+
+       o A  report  interval  (see  below)  will  adjust start/end dates, when
+         needed, so that they fall on subperiod boundaries.
+
+       Examples:
+
+
+       -b 2016/3/17       begin on St. Patrick's day 2016
+       -e 12/1            end  at  the  start  of  december  1st of the current year
+                          (11/30 will be the last date included)
+       -b thismonth       all transactions on or after the 1st of the current month
+       -p thismonth       all transactions in the current month
+       date:2016/3/17..   the  above  written  as  queries  instead  (.. can also be
+                          replaced with -)
+       date:..12/1
+       date:thismonth..
+       date:thismonth
+
+   Report intervals
+       A report interval can be specified so that commands like register, bal-
+       ance and activity become multi-period, showing each subperiod as a sep-
+       arate row or column.
+
+       The following "standard" report intervals can be enabled by using their
+       corresponding flag:
+
+       -D/--daily, -W/--weekly, -M/--monthly, -Q/--quarterly, -Y/--yearly.
+
+       These standard intervals always start on natural  interval  boundaries:
+       eg  --weekly  starts  on  mondays, --monthly starts on the first of the
+       month, --yearly always starts on January 1st, etc.
+
+       Certain more complex intervals, and more flexible boundary  dates,  can
+       be  specified  by  -p/--period.   These are described in period expres-
+       sions, below.
+
+       Report intervals can only be specified by the flags above, and  not  by
+       query arguments, currently.
+
+       Report  intervals  have another effect: multi-period reports are always
+       expanded to fill a whole number of subperiods.  So if you use a  report
+       interval  (other  than  --daily), and you have specified a start or end
+       date, you may notice those  dates  being  overridden  (ie,  the  report
+       starts  earlier than your requested start date, or ends later than your
+       requested end date).  This is done to ensure "full" first and last sub-
+       periods, so that all subperiods' numbers are comparable.
+
+   Period expressions
+       The  -p/--period  option accepts period expressions, a shorthand way of
+       expressing a start date, end date, and/or report interval all at  once.
+
+       Here's  a basic period expression specifying the first quarter of 2009.
+       Note, hledger always treats start dates as inclusive and end  dates  as
+       exclusive:
+
+       -p "from 2009/1/1 to 2009/4/1"
+
+       Keywords  like  "from" and "to" are optional, and so are the spaces, as
+       long as you don't run two dates together.  "to" can also be written  as
+       ".." or "-".  These are equivalent to the above:
+
+
+       -p "2009/1/1 2009/4/1"
+       -p2009/1/1to2009/4/1
+       -p2009/1/1..2009/4/1
+
+       Dates  are  smart  dates, so if the current year is 2009, the above can
+       also be written as:
+
+
+       -p "1/1 4/1"
+
+       -p "january-apr"
+       -p "this year to 4/1"
+
+       If you specify only one date, the missing start or end date will be the
+       earliest or latest transaction in your journal:
+
+
+       -p "from 2009/1/1"   everything  after  january
+                            1, 2009
+       -p "from 2009/1"     the same
+       -p "from 2009"       the same
+       -p "to 2009"         everything before  january
+                            1, 2009
+
+       A  single  date  with  no "from" or "to" defines both the start and end
+       date like so:
+
+
+       -p "2009"       the year 2009;  equivalent
+                       to "2009/1/1 to 2010/1/1"
+       -p "2009/1"     the  month of jan; equiva-
+                       lent   to   "2009/1/1   to
+                       2009/2/1"
+       -p "2009/1/1"   just  that day; equivalent
+                       to "2009/1/1 to 2009/1/2"
+
+       Or you can specify a single quarter like so:
+
+
+       -p "2009Q1"   first  quarter  of   2009,
+                     equivalent to "2009/1/1 to
+                     2009/4/1"
+       -p "q4"       fourth quarter of the cur-
+                     rent year
+
+       The  argument  of  -p  can  also  begin  with, or be, a report interval
+       expression.  The basic report intervals  are  daily,  weekly,  monthly,
+       quarterly, or yearly, which have the same effect as the -D,-W,-M,-Q, or
+       -Y flags.  Between report interval and start/end dates  (if  any),  the
+       word in is optional.  Examples:
+
+
+       -p "weekly from 2009/1/1 to 2009/4/1"
+       -p "monthly in 2008"
+       -p "quarterly"
+
+       Note  that  weekly, monthly, quarterly and yearly intervals will always
+       start on the first day on week, month, quarter or year accordingly, and
+       will  end  on  the  last  day of same period, even if associated period
+       expression specifies different explicit start and end date.
+
+       For example:
+
+
+       -p "weekly from  2009/1/1   starts on 2008/12/29, closest preceding Mon-
+       to 2009/4/1"                day
+       -p      "monthly       in   starts on 2018/11/01
+       2008/11/25"
+       -p     "quarterly    from   starts  on  2009/04/01,  ends on 2009/06/30,
+       2009-05-05 to 2009-06-01"   which are first and last days of Q2 2009
+       -p      "yearly      from   starts on 2009/01/01, first day of 2009
+       2009-12-29"
+
+       The  following  more  complex  report  intervals  are  also  supported:
+       biweekly, fortnightly,  bimonthly,  every  day|week|month|quarter|year,
+       every N days|weeks|months|quarters|years.
+
+       All  of  these  will start on the first day of the requested period and
+       end on the last one, as described above.
+
+       Examples:
+
+
+       -p "bimonthly from 2008"    periods will have boundaries on  2008/01/01,
+                                   2008/03/01, ...
+       -p "every 2 weeks"          starts on closest preceding Monday
+       -p  "every  5  month from   periods will have boundaries on  2009/03/01,
+       2009/03"                    2009/08/01, ...
+
+       If  you want intervals that start on arbitrary day of your choosing and
+       span a week, month or year, you need to use any of the following:
+
+       every    Nth     day     of     week,     every     WEEKDAYNAME     (eg
+       mon|tue|wed|thu|fri|sat|sun), every Nth day [of month], every Nth WEEK-
+       DAYNAME [of month], every MM/DD [of year], every  Nth  MMM  [of  year],
+       every MMM Nth [of year].
+
+       Examples:
+
+
+       -p  "every  2nd  day  of   periods will go from Tue to Tue
+       week"
+       -p "every Tue"             same
+       -p "every 15th day"        period boundaries will  be  on  15th  of  each
+                                  month
+       -p "every 2nd Monday"      period  boundaries will be on second Monday of
+                                  each month
+       -p "every 11/05"           yearly periods with boundaries on 5th of Nov
+       -p "every 5th Nov"         same
+       -p "every Nov 5th"         same
+
+       Show historical balances at end of 15th each month (N is exclusive  end
+       date):
+
+       hledger balance -H -p "every 16th day"
+
+       Group  postings  from  start  of wednesday to end of next tuesday (N is
+       start date and exclusive end date):
+
+       hledger register checking -p "every 3rd day of week"
+
+DEPTH
+       With the --depth N option (short form: -N), commands like account, bal-
+       ance  and register will show only the uppermost accounts in the account
+       tree, down to level N.  Use this when you  want  a  summary  with  less
+       detail.   This  flag has the same effect as a depth: query argument (so
+       -2, --depth=2 or depth:2 are equivalent).
+
+QUERIES
+       One of hledger's strengths is being able to quickly report on a precise
+       subset of your data.  Most hledger commands accept optional query argu-
+       ments to restrict their scope.  The syntax is as follows:
+
+       o Zero or more space-separated  query  terms.   These  are  most  often
+         account name substrings:
+
+         utilities food:groceries
+
+       o Terms  with  spaces or other special characters should be enclosed in
+         quotes:
+
+         "personal care"
+
+       o Regular expressions are also supported:
+
+         "^expenses\b" "accounts (payable|receivable)"
+
+       o Add a query type prefix to match other parts of the data:
+
+         date:202012- desc:amazon cur:USD amt:">100" status:
+
+       o Add a not: prefix to negate a term:
+
+         not:cur:USD
+
+   Query types
+       Here are the types of query term available.  Remember these can also be
+       prefixed with not: to convert them into a negative match.
+
+       acct:REGEX, REGEX
+       Match  account names containing this (case insensitive) regular expres-
+       sion.  This is the default query type when there is no prefix, and reg-
+       ular  expression  syntax  is  typically  not needed, so usually we just
+       write an account name substring, like expenses or food.
+
+       amt:N, amt:<N, amt:<=N, amt:>N, amt:>=N
+       Match postings with a single-commodity amount equal to, less  than,  or
+       greater  than N.  (Postings with multi-commodity amounts are not tested
+       and will always match.) The comparison has two modes: if N is  preceded
+       by  a + or - sign (or is 0), the two signed numbers are compared.  Oth-
+       erwise, the absolute magnitudes are compared, ignoring sign.
+
+       code:REGEX
+       Match by transaction code (eg check number).
+
+       cur:REGEX
+       Match  postings  or  transactions  including  any  amounts  whose  cur-
+       rency/commodity  symbol  is  fully  matched  by  REGEX.  (For a partial
+       match, use .*REGEX.*).  Note, to match  special  characters  which  are
+       regex-significant,  you need to escape them with \.  And for characters
+       which are significant to your shell you may  need  one  more  level  of
+       escaping.  So eg to match the dollar sign:
+       hledger print cur:\\$.
+
+       desc:REGEX
+       Match transaction descriptions.
+
+       date:PERIODEXPR
+       Match  dates  (or  with  the  --date2 flag, secondary dates) within the
+       specified period.  PERIODEXPR is a period  expression  with  no  report
+       interval.  Examples:
+       date:2016, date:thismonth, date:2/1-2/15, date:2021-07-27..nextquarter.
+
+       date2:PERIODEXPR
+       Match secondary dates within the specified period (independent  of  the
+       --date2 flag).
+
+       depth:N
+       Match  (or  display,  depending  on  command) accounts at or above this
+       depth.
+
+       note:REGEX
+       Match transaction notes (the part of the description right of |, or the
+       whole description if there's no |).
+
+       payee:REGEX
+       Match  transaction  payee/payer names (the part of the description left
+       of |, or the whole description if there's no |).
+
+       real:, real:0
+       Match real or virtual postings respectively.
+
+       status:, status:!, status:*
+       Match unmarked, pending, or cleared transactions respectively.
+
+       tag:REGEX[=REGEX]
+       Match by tag name, and optionally also by tag value.  (To match only by
+       value,  use  tag:.=REGEX.)  Note  that  postings also inherit tags from
+       their transaction, and transactions also acquire tags from their  post-
+       ings, when querying.
+
+       (inacct:ACCTNAME
+       A  special  query  term  used  automatically in hledger-web only: tells
+       hledger-web to show the transaction register for an account.)
+
+   Combining query terms
+       Most commands select things which match:
+
+       o any of the description terms AND
+
+       o any of the account terms AND
+
+       o any of the status terms AND
+
+       o all the other terms.
+
+       while the print command shows transactions which:
+
+       o match any of the description terms AND
+
+       o have any postings matching any of the positive account terms AND
+
+       o have no postings matching any of the negative account terms AND
+
+       o match all the other terms.
+
+       You can do more powerful queries (such as AND-ing two  like  terms)  by
+       running  a  first query with print, and piping the result into a second
+       hledger command.  Eg: how much of food expenses was paid with cash ?
+
+              $ hledger print assets:cash | hledger f- -I balance expenses:food
+
+       If you are interested in full  boolean  expressions  for  queries,  see
+       #203.
+
+   Queries and command options
+       Some  queries can also be expressed as command-line options: depth:2 is
+       equivalent to --depth 2, date:2020 is equivalent to -p 2020, etc.  When
+       you  mix  command  options and query arguments, generally the resulting
+       query is their intersection.
+
+   Queries and account aliases
+       When account names are rewritten with  --alias  or  alias,  acct:  will
+       match either the old or the new account name.
+
+   Queries and valuation
+       When  amounts  are  converted  to  other  commodities  in cost or value
+       reports, cur: and amt: match the  old  commodity  symbol  and  the  old
+       amount  quantity, not the new ones (except in hledger 1.22.0 where it's
+       reversed, see #1625).
+
+   Querying with account aliases
+       When account names are rewritten with --alias or alias, note that acct:
+       will match either the old or the new account name.
+
+   Querying with cost or value
+       When  amounts  are  converted  to  other  commodities  in cost or value
+       reports, note that cur: matches the new commodity symbol, and  not  the
+       old one, and amt: matches the new quantity, and not the old one.  Note:
+       this changed in hledger 1.22, previously it was the  reverse,  see  the
+       discussion at #1625.
+
+COSTING
+       The  -B/--cost  flag  converts  amounts to their cost or sale amount at
+       transaction time, if they have a transaction price specified.  If  this
+       flag  is supplied, hledger will perform cost conversion first, and will
+       apply any market price valuations (if requested) afterwards.
+
+VALUATION
+       Instead of reporting amounts in their original commodity,  hledger  can
+       convert them to cost/sale amount (using the conversion rate recorded in
+       the transaction), and/or to market value (using some market price on  a
+       certain  date).   This  is  controlled  by the --value=TYPE[,COMMODITY]
+       option, which will be described below.  We also provide the simpler  -V
+       and -X COMMODITY options, and often one of these is all you need:
+
+   -V: Value
+       The  -V/--market flag converts amounts to market value in their default
+       valuation commodity, using the market prices in effect on the valuation
+       date(s), if any.  More on these in a minute.
+
+   -X: Value in specified commodity
+       The -X/--exchange=COMM option is like -V, except you tell it which cur-
+       rency you want to convert to, and it tries  to  convert  everything  to
+       that.
+
+   Valuation date
+       Since  market  prices  can change from day to day, market value reports
+       have a valuation date (or more than one), which determines which market
+       prices will be used.
+
+       For single period reports, if an explicit report end date is specified,
+       that will be used as the valuation date; otherwise the  valuation  date
+       is the journal's end date.
+
+       For  multiperiod  reports, each column/period is valued on the last day
+       of the period, by default.
+
+   Market prices
+       To convert a commodity A to its market value in  another  commodity  B,
+       hledger  looks  for a suitable market price (exchange rate) as follows,
+       in this order of preference :
+
+       1. A declared market price or inferred market price: A's latest  market
+          price in B on or before the valuation date as declared by a P direc-
+          tive, or (with the --infer-market-price flag) inferred from transac-
+          tion prices.
+
+       2. A reverse market price: the inverse of a declared or inferred market
+          price from B to A.
+
+       3. A forward chain of market prices: a synthetic price formed  by  com-
+          bining the shortest chain of "forward" (only 1 above) market prices,
+          leading from A to B.
+
+       4. Any chain of market prices: a chain of any market prices,  including
+          both  forward  and reverse prices (1 and 2 above), leading from A to
+          B.
+
+       There is a limit to the  length  of  these  price  chains;  if  hledger
+       reaches  that length without finding a complete chain or exhausting all
+       possibilities, it will give up (with a "gave  up"  message  visible  in
+       --debug=2 output).  That limit is currently 1000.
+
+       Amounts  for  which no suitable market price can be found, are not con-
+       verted.
+
+   --infer-market-price: market prices from transactions
+       Normally, market value in hledger is fully controlled by, and requires,
+       P directives in your journal.  Since adding and updating those can be a
+       chore, and since transactions usually take place  at  close  to  market
+       value, why not use the recorded transaction prices as additional market
+       prices (as Ledger does) ?  We could produce value reports without need-
+       ing P directives at all.
+
+       Adding the --infer-market-price flag to -V, -X or --value enables this.
+       So for example, hledger bs  -V  --infer-market-price  will  get  market
+       prices  both  from  P  directives  and from transactions.  (And if both
+       occur on the same day, the P directive takes precedence).
+
+       There is a downside: value reports can sometimes be affected in confus-
+       ing/undesired  ways  by  your journal entries.  If this happens to you,
+       read all of this Valuation section carefully, and try adding --debug or
+       --debug=2 to troubleshoot.
+
+       --infer-market-price can infer market prices from:
+
+       o multicommodity transactions with explicit prices (@/@@)
+
+       o multicommodity  transactions with implicit prices (no @, two commodi-
+         ties, unbalanced).  (With  these,  the  order  of  postings  matters.
+         hledger print -x can be useful for troubleshooting.)
+
+       o but  not,  currently, from "more correct" multicommodity transactions
+         (no @, multiple commodities, balanced).
+
+   Valuation commodity
+       When you specify a valuation commodity (-X COMM or --value TYPE,COMM):
+       hledger will convert all amounts to COMM, wherever it can find a  suit-
+       able market price (including by reversing or chaining prices).
+
+       When  you  leave  the  valuation  commodity  unspecified (-V or --value
+       TYPE):
+       For each commodity A, hledger picks a default  valuation  commodity  as
+       follows, in this order of preference:
+
+       1. The price commodity from the latest P-declared market price for A on
+          or before valuation date.
+
+       2. The price commodity from the latest P-declared market price for A on
+          any  date.   (Allows  conversion  to proceed when there are inferred
+          prices before the valuation date.)
+
+       3. If there are no P directives at all (any commodity or date) and  the
+          --infer-market-price flag is used: the price commodity from the lat-
+          est transaction-inferred price for A on or before valuation date.
+
+       This means:
+
+       o If you have P directives, they determine which  commodities  -V  will
+         convert, and to what.
+
+       o If  you  have no P directives, and use the --infer-market-price flag,
+         transaction prices determine it.
+
+       Amounts for which no valuation commodity can  be  found  are  not  con-
+       verted.
+
+   Simple valuation examples
+       Here are some quick examples of -V:
+
+              ; one euro is worth this many dollars from nov 1
+              P 2016/11/01 EUR $1.10
+
+              ; purchase some euros on nov 3
+              2016/11/3
+                  assets:euros        EUR100
+                  assets:checking
+
+              ; the euro is worth fewer dollars by dec 21
+              P 2016/12/21 EUR $1.03
+
+       How many euros do I have ?
+
+              $ hledger -f t.j bal -N euros
+                              EUR100  assets:euros
+
+       What are they worth at end of nov 3 ?
+
+              $ hledger -f t.j bal -N euros -V -e 2016/11/4
+                           $110.00  assets:euros
+
+       What  are they worth after 2016/12/21 ?  (no report end date specified,
+       defaults to today)
+
+              $ hledger -f t.j bal -N euros -V
+                           $103.00  assets:euros
+
+   --value: Flexible valuation
+       -V and -X are special cases of the more general --value option:
+
+               --value=TYPE[,COMM]  TYPE is then, end, now or YYYY-MM-DD.
+                                    COMM is an optional commodity symbol.
+                                    Shows amounts converted to:
+                                    - default valuation commodity (or COMM) using market prices at posting dates
+                                    - default valuation commodity (or COMM) using market prices at period end(s)
+                                    - default valuation commodity (or COMM) using current market prices
+                                    - default valuation commodity (or COMM) using market prices at some date
+
+       The TYPE part selects cost or value and valuation date:
+
+       --value=then
+              Convert amounts to their value in the default valuation  commod-
+              ity, using market prices on each posting's date.
+
+       --value=end
+              Convert  amounts to their value in the default valuation commod-
+              ity, using market prices on the last day of  the  report  period
+              (or  if  unspecified, the journal's end date); or in multiperiod
+              reports, market prices on the last day of each subperiod.
+
+       --value=now
+              Convert amounts to their value in the default valuation  commod-
+              ity  using  current  market  prices (as of when report is gener-
+              ated).
+
+       --value=YYYY-MM-DD
+              Convert amounts to their value in the default valuation  commod-
+              ity using market prices on this date.
+
+       To select a different valuation commodity, add the optional ,COMM part:
+       a comma, then the  target  commodity's  symbol.   Eg:  --value=now,EUR.
+       hledger will do its best to convert amounts to this commodity, deducing
+       market prices as described above.

+
+       You  may  need  to  explicitly  set  a  commodity's display style, when
+       reverse prices are used.  Eg this output might be surprising:
+
+              P 2000-01-01 A 2B
+
+              2000-01-01
+                a  1B
+                b
+
+              $ hledger print -x -X A
+              2000-01-01
+                  a               0
+                  b               0
+
+       Explanation: because there's no amount or commodity directive  specify-
+       ing  a display style for A, 0.5A gets the default style, which shows no
+       decimal digits.  Because the displayed amount looks like zero, the com-
+       modity  symbol  and minus sign are not displayed either.  Adding a com-
+       modity directive sets a more useful display style for A:
+
+              P 2000-01-01 A 2B
+              commodity 0.00A
+
+              2000-01-01
+                a  1B
+                b
+
+              $ hledger print -X A
+              2000-01-01
+                  a           0.50A
+                  b          -0.50A
+
+   Effect of valuation on reports
+       Here is a reference for how valuation is supposed to affect  each  part
+       of  hledger's  reports  (and  a  glossary).  (It's wide, you'll have to
+       scroll sideways.) It may be useful when troubleshooting.  If  you  find
+       problems,  please  report  them,  ideally  with a reproducible example.

+       report interval
+              a  flag (-D/-W/-M/-Q/-Y) or period expression that activates the

+              ods).
+
+PIVOTING
+       Normally hledger sums amounts, and organizes them in a hierarchy, based
+       on account name.  The --pivot FIELD option causes it to sum  and  orga-
+       nize  hierarchy  based on the value of some other field instead.  FIELD
+       can be: code, description, payee, note, or the full name (case insensi-
+       tive) of any tag.  As with account names, values containing colon:sepa-
+       rated:parts will be displayed hierarchically in reports.
+
+       --pivot is a general option affecting all reports;  you  can  think  of
+       hledger transforming the journal before any other processing, replacing
+       every posting's account name with the value of the specified  field  on
+       that posting, inheriting it from the transaction or using a blank value
+       if it's not present.
+
+       An example:
+
+              2016/02/16 Member Fee Payment
+                  assets:bank account                    2 EUR
+                  income:member fees                    -2 EUR  ; member: John Doe
+
+       Normal balance report showing account names:
+
+              $ hledger balance
+                             2 EUR  assets:bank account
+                            -2 EUR  income:member fees
+              --------------------
+                                 0
+
+       Pivoted balance report, using member: tag values instead:
+
+              $ hledger balance --pivot member
+                             2 EUR
+                            -2 EUR  John Doe
+              --------------------
+                                 0
+
+       One way to show only amounts with  a  member:  value  (using  a  query,
+       described below):
+
+              $ hledger balance --pivot member tag:member=.
+                            -2 EUR  John Doe
+              --------------------
+                            -2 EUR
+
+       Another  way  (the  acct:  query  matches  against the pivoted "account
+       name"):
+
+              $ hledger balance --pivot member acct:.
+                            -2 EUR  John Doe
+              --------------------
+                            -2 EUR
+
+OUTPUT
+   Output destination
+       hledger commands send their output to the terminal by default.  You can
+       of course redirect this, eg into a file, using standard shell syntax:
+
+              $ hledger print > foo.txt
+
+       Some  commands (print, register, stats, the balance commands) also pro-
+       vide the -o/--output-file option, which does  the  same  thing  without
+       needing the shell.  Eg:
+
+              $ hledger print -o foo.txt
+              $ hledger print -o -        # write to stdout (the default)
+
+       hledger   can   optionally   produce  debug  output  (if  enabled  with
+       --debug=N); this goes to stderr, and is not  affected  by  -o/--output-
+       file.   If you need to capture it, use shell redirects, eg: hledger bal
+       --debug=3 >file 2>&1.
+
+   Output format
+       Some commands (print, register, the balance commands) offer a choice of
+       output format.  In addition to the usual plain text format (txt), there
+       are CSV (csv), HTML (html), JSON (json) and SQL (sql).   This  is  con-
+       trolled by the -O/--output-format option:
+
+              $ hledger print -O csv
+
+       or, by a file extension specified with -o/--output-file:
+
+              $ hledger balancesheet -o foo.html   # write HTML to foo.html
+
+       The -O option can be used to override the file extension if needed:
+
+              $ hledger balancesheet -o foo.txt -O html   # write HTML to foo.txt
+
+       Some notes about JSON output:
+
+       o This  feature  is  marked  experimental,  and  not yet much used; you
+         should expect our JSON to evolve.  Real-world feedback is welcome.
+
+       o Our JSON is rather large and verbose, as it is quite a faithful  rep-
+         resentation  of  hledger's  internal  data  types.  To understand the
+         JSON,  read  the  Haskell  type  definitions,  which  are  mostly  in
+         https://github.com/simonmichael/hledger/blob/master/hledger-
+         lib/Hledger/Data/Types.hs.
+
+       o hledger represents quantities as Decimal values  storing  up  to  255
+         significant  digits,  eg  for  repeating  decimals.  Such numbers can
+         arise in practice (from automatically-calculated transaction prices),
+         and  would break most JSON consumers.  So in JSON, we show quantities
+         as simple Numbers with at most 10 decimal places.  We don't limit the
+         number  of  integer  digits, but that part is under your control.  We
+         hope this approach will not cause problems in practice; if  you  find
+         otherwise, please let us know.  (Cf #1195)
+
+       Notes about SQL output:
+
+       o SQL  output is also marked experimental, and much like JSON could use
+         real-world feedback.
+
+       o SQL output is expected to work with sqlite, MySQL and PostgreSQL
+
+       o SQL output is structured with the expectations that  statements  will
+         be  executed  in the empty database.  If you already have tables cre-
+         ated via SQL output of hledger, you would  probably  want  to  either
+         clear tables of existing data (via delete or truncate SQL statements)
+         or drop tables completely as otherwise your postings will be duped.
+
+COMMANDS
+       hledger provides a number of commands for producing reports and  manag-
+       ing  your  data.   Run  hledger  with no arguments to list the commands
+       available, and hledger CMD to run a command.  CMD can be the full  com-
+       mand  name, or its standard abbreviation shown in the commands list, or
+       any unambiguous prefix of the name.  Eg: hledger bal.
+
+       Here are the built-in commands, with the most often-used in bold:

+
+       Add-on commands:
+
+       Programs or scripts named hledger-SOMETHING in  your  PATH  are  add-on
+       commands;  these  appear  in  the  commands list with a + mark.  Two of
+       these are maintained and released with hledger:
+
+       o ui - an efficient terminal interface (TUI) for hledger
+
+       o web - a simple web interface (WUI) for hledger
+
+       And these add-ons are maintained separately:
+
+       o iadd - a more interactive alternative for the add command
+
+       o interest -  generates  interest  transactions  according  to  various
+         schemes

+
+       Next, the detailed command docs, in alphabetical order.
+
+   accounts
+       accounts
+       Show account names.
+
+       This command lists account names, either declared with  account  direc-
+       tives  (--declared),  posted  to (--used), or both (the default).  With
+       query arguments, only matched account names and  account  names  refer-
+       enced  by matched postings are shown.  It shows a flat list by default.
+       With --tree, it uses indentation to show  the  account  hierarchy.   In
+       flat  mode you can add --drop N to omit the first few account name com-
+       ponents.  Account names can be depth-clipped with depth:N or --depth  N
+       or -N.
+
+       Examples:
+
+              $ hledger accounts
+              assets:bank:checking
+              assets:bank:saving
+              assets:cash
+              expenses:food
+              expenses:supplies
+              income:gifts
+              income:salary
+              liabilities:debts
+
+   activity
+       activity
+       Show an ascii barchart of posting counts per interval.
+
+       The  activity  command  displays an ascii histogram showing transaction
+       counts by day, week, month or other reporting interval (by day  is  the
+       default).  With query arguments, it counts only matched transactions.
+
+       Examples:
+
+              $ hledger activity --quarterly
+              2008-01-01 **
+              2008-04-01 *******
+              2008-07-01
+              2008-10-01 **
+
+   add
+       add
+       Prompt  for  transactions  and  add them to the journal.  Any arguments
+       will be used as default inputs for the first N prompts.
+
+       Many hledger users edit their journals directly with a text editor,  or
+       generate  them from CSV.  For more interactive data entry, there is the
+       add command, which prompts interactively on the console for new  trans-
+       actions, and appends them to the journal file (if there are multiple -f
+       FILE options, the first file is used.) Existing  transactions  are  not
+       changed.   This  is the only hledger command that writes to the journal
+       file.
+
+       To use it, just run hledger add and follow the prompts.  You can add as
+       many  transactions as you like; when you are finished, enter . or press
+       control-d or control-c to exit.
+
+       Features:
+
+       o add tries to provide useful defaults,  using  the  most  similar  (by
+         description)  recent transaction (filtered by the query, if any) as a
+         template.
+
+       o You can also set the initial defaults with command line arguments.
+
+       o Readline-style edit keys can be used during data entry.
+
+       o The tab key will auto-complete whenever possible - accounts, descrip-
+         tions,  dates  (yesterday,  today,  tomorrow).   If the input area is
+         empty, it will insert the default value.
+
+       o If the journal defines a default commodity, it will be added  to  any
+         bare numbers entered.
+
+       o A parenthesised transaction code may be entered following a date.
+
+       o Comments and tags may be entered following a description or amount.
+
+       o If you make a mistake, enter < at any prompt to go one step backward.
+
+       o Input prompts are displayed in a different colour when  the  terminal
+         supports it.
+
+       Example (see the tutorial for a detailed explanation):
+
+              $ hledger add
+              Adding transactions to journal file /src/hledger/examples/sample.journal
+              Any command line arguments will be used as defaults.
+              Use tab key to complete, readline keys to edit, enter to accept defaults.
+              An optional (CODE) may follow transaction dates.
+              An optional ; COMMENT may follow descriptions or amounts.
+              If you make a mistake, enter < at any prompt to go one step backward.
+              To end a transaction, enter . when prompted.
+              To quit, enter . at a date prompt or press control-d or control-c.
+              Date [2015/05/22]:
+              Description: supermarket
+              Account 1: expenses:food
+              Amount  1: $10
+              Account 2: assets:checking
+              Amount  2 [$-10.0]:
+              Account 3 (or . or enter to finish this transaction): .
+              2015/05/22 supermarket
+                  expenses:food             $10
+                  assets:checking        $-10.0
+
+              Save this transaction to the journal ? [y]:
+              Saved.
+              Starting the next transaction (. or ctrl-D/ctrl-C to quit)
+              Date [2015/05/22]: <CTRL-D> $
+
+       On  Microsoft  Windows,  the add command makes sure that no part of the
+       file path ends with a period, as that would cause problems (#1056).
+
+   aregister
+       aregister, areg
+
+       Show the transactions  and  running  historical  balance  of  a  single
+       account, with each transaction displayed as one line.
+
+       aregister shows the overall transactions affecting a particular account
+       (and any subaccounts).  Each report line represents one transaction  in
+       this  account.   Transactions  before  the report start date are always
+       included in the running balance (--historical mode is always on).
+
+       This is a more "real world", bank-like view than the  register  command
+       (which  shows individual postings, possibly from multiple accounts, not
+       necessarily in historical mode).  As a quick rule of thumb: - use areg-
+       ister for reviewing and reconciling real-world asset/liability accounts
+       - use register for reviewing detailed revenues/expenses.
+
+       aregister requires one argument: the account to  report  on.   You  can
+       write  either  the  full  account  name,  or a case-insensitive regular
+       expression which will select the alphabetically first matched  account.
+       (Eg  if  you have assets:aaa:checking and assets:bbb:checking accounts,
+       hledger areg checking would select assets:aaa:checking.)
+
+       Transactions involving subaccounts of this account will also be  shown.
+       aregister  ignores depth limits, so its final total will always match a
+       balance report with similar arguments.
+
+       Any additional arguments form a query which will  filter  the  transac-
+       tions shown.  Note some queries will disturb the running balance, caus-
+       ing it to be different from the account's real-world running balance.
+
+       An example: this shows the transactions and historical running  balance
+       during july, in the first account whose name contains "checking":
+
+              $ hledger areg checking date:jul
+
+       Each aregister line item shows:
+
+       o the  transaction's date (or the relevant posting's date if different,
+         see below)
+
+       o the names of all the other account(s) involved  in  this  transaction
+         (probably abbreviated)
+
+       o the total change to this account's balance from this transaction
+
+       o the account's historical running balance after this transaction.
+
+       Transactions  making a net change of zero are not shown by default; add
+       the -E/--empty flag to show them.
+
+       This command also supports the output  destination  and  output  format
+       options.  The output formats supported are txt, csv, and json.
+
+   aregister and custom posting dates
+       Transactions  whose  date  is  outside  the  report period can still be
+       shown, if they have a posting to this account dated inside  the  report
+       period.   (And  in this case it's the posting date that is shown.) This
+       ensures that aregister can show an accurate historical running balance,
+       matching the one shown by register -H with the same arguments.
+
+       To  filter  strictly  by  transaction date instead, add the --txn-dates
+       flag.  If you use this flag and  some  of  your  postings  have  custom
+       dates, it's probably best to assume the running balance is wrong.
+
+   balance
+       balance, bal
+       Show accounts and their balances.
+
+       balance  is  one  of  hledger's oldest and most versatile commands, for
+       listing account balances, balance changes, values,  value  changes  and
+       more, during one time period or many.  Generally it shows a table, with
+       rows representing accounts, and columns representing periods.
+
+       Note there are some higher-level variants of the balance  command  with
+       convenient  defaults,  which  can be simpler to use: balancesheet, bal-
+       ancesheetequity, cashflow and incomestatement.  When you need more con-
+       trol, then use balance.
+
+   balance features
+       Here's  a quick overview of the balance command's features, followed by
+       more detailed descriptions and examples.  Many of these work  with  the
+       higher-level commands as well.
+
+       balance can show..
+
+       o accounts as a list (-l) or a tree (-t)
+
+       o optionally depth-limited (-[1-9])
+
+       o sorted by declaration order and name, or by amount
+
+       ..and their..
+
+       o balance changes (the default)
+
+       o or actual and planned balance changes (--budget)
+
+       o or value of balance changes (-V)
+
+       o or change of balance values (--valuechange)
+
+       ..in..
+
+       o one time period (the whole journal period by default)
+
+       o or multiple periods (-D, -W, -M, -Q, -Y, -p INTERVAL)
+
+       ..either..
+
+       o per period (the default)
+
+       o or accumulated since report start date (--cumulative)
+
+       o or accumulated since account creation (--historical/-H)
+
+       ..possibly converted to..
+
+       o cost (--value=cost[,COMM]/--cost/-B)
+
+       o or market value, as of transaction dates (--value=then[,COMM])
+
+       o or at period ends (--value=end[,COMM])
+
+       o or now (--value=now)
+
+       o or at some other date (--value=YYYY-MM-DD)
+
+       ..with..
+
+       o totals   (-T),   averages   (-A),  percentages  (-%),  inverted  sign
+         (--invert)
+
+       o rows and columns swapped (--transpose)
+
+       o another field used as account name (--pivot)
+
+       o custom-formatted line items (single-period reports only) (--format)
+
+       This command supports the output destination and output format options,
+       with  output  formats  txt, csv, json, and (multi-period reports only:)
+       html.  In txt output in a colour-supporting terminal, negative  amounts
+       are shown in red.
+
+   Simple balance report
+       With  no  arguments,  balance  shows  a  list of all accounts and their
+       change of balance - ie, the sum of posting amounts,  both  inflows  and
+       outflows  -  during  the  entire period of the journal.  For real-world
+       accounts, this should also match their end balance at the  end  of  the
+       journal period (more on this below).
+
+       Accounts  are  sorted  by declaration order if any, and then alphabeti-
+       cally by account name.  For instance, using examples/sample.journal:
+
+              $ hledger bal
+                                $1  assets:bank:saving
+                               $-2  assets:cash
+                                $1  expenses:food
+                                $1  expenses:supplies
+                               $-1  income:gifts
+                               $-1  income:salary
+                                $1  liabilities:debts
+              --------------------
+                                 0
+
+       Accounts with a zero balance (and no non-zero subaccounts, in tree mode
+       -  see  below)  are  hidden  by  default.   Use -E/--empty to show them
+       (revealing assets:bank:checking here):
+
+              $ hledger -f examples/sample.journal  bal  -E
+                                 0  assets:bank:checking
+                                $1  assets:bank:saving
+                               $-2  assets:cash
+                                $1  expenses:food
+                                $1  expenses:supplies
+                               $-1  income:gifts
+                               $-1  income:salary
+                                $1  liabilities:debts
+              --------------------
+                                 0
+
+       The total of the amounts displayed is shown as the  last  line,  unless
+       -N/--no-total is used.
+
+   Filtered balance report
+       You  can  show  fewer  accounts,  a  different time period, totals from
+       cleared transactions only, etc.  by using query arguments or options to
+       limit the postings being matched.  Eg:
+
+              $ hledger bal --cleared assets date:200806
+                               $-2  assets:cash
+              --------------------
+                               $-2
+
+   List or tree mode
+       By  default,  or with -l/--flat, accounts are shown as a flat list with
+       their full names visible, as in the examples above.
+
+       With -t/--tree, the  account  hierarchy  is  shown,  with  subaccounts'
+       "leaf" names indented below their parent:
+
+              $ hledger balance
+                               $-1  assets

+
+       Notes:
+
+       o "Boring" accounts are combined with their subaccount for more compact
+         output, unless --no-elide is used.  Boring accounts have  no  balance
+         of  their own and just one subaccount (eg assets:bank and liabilities
+         above).
+
+       o All balances shown are "inclusive", ie including  the  balances  from
+         all  subaccounts.   Note  this  means  some repetition in the output,
+         which requires explanation when sharing reports with non-plaintextac-
+         counting-users.   A  tree mode report's final total is the sum of the
+         top-level balances shown, not of all the balances shown.
+
+       o Each group of sibling accounts (ie, under a common parent) is  sorted
+         separately.
+
+   Depth limiting
+       With  a depth:N query, or --depth N option, or just -N, balance reports
+       will show accounts only to the specified depth, hiding the deeper  sub-
+       accounts.   Account balances at the depth limit always include the bal-
+       ances from any hidden subaccounts (even in list  mode).   This  can  be
+       useful for getting an overview.  Eg, limiting to depth 1:
+
+              $ hledger balance -N -1
+                               $-1  assets
+                                $2  expenses
+                               $-2  income
+                                $1  liabilities
+
+       You  can  also hide top-level account name parts, using --drop N.  This
+       can be useful for hiding repetitive top-level account names:
+
+              $ hledger bal expenses --drop 1
+                                $1  food
+                                $1  supplies

+       ance shows a tabular report, with columns representing successive  time

+
+       Notes:
+
+       o The report's start/end dates will be expanded, if necessary, to fully
+         encompass the displayed subperiods (so that the first and last subpe-
+         riods have the same duration as the others).
+
+       o Leading  and trailing periods (columns) containing all zeroes are not
+         shown, unless -E/--empty is used.
+
+       o Accounts  (rows)  containing  all  zeroes  are  not   shown,   unless
+         -E/--empty is used.
+
+       o Amounts  with  many commodities are shown in abbreviated form, unless
+         --no-elide is used.  (experimental)
+
+       o Average and/or total columns can be added with the  -A/--average  and
+         -T/--row-total flags.
+
+       o The --transpose flag can be used to exchange rows and columns.
+
+       o The  --pivot  FIELD option causes a different transaction field to be
+         used as "account name".  See PIVOTING.
+
+       Multi-period reports with many periods can be too wide for easy viewing
+       in the terminal.  Here are some ways to handle that:
+
+       o Hide the totals row with -N/--no-total
+
+       o Convert to a single currency with -V
+
+       o Maximize the terminal window
+
+       o Reduce the terminal's font size
+
+       o View  with  a  pager like less, eg: hledger bal -D --color=yes | less
+         -RS
+
+       o Output as CSV and use a CSV viewer like visidata (hledger bal  -D  -O
+         csv  |  vd  -f  csv),  Emacs'  csv-mode (M-x csv-mode, C-c C-a), or a
+         spreadsheet (hledger bal -D -o a.csv && open a.csv)
+
+       o Output as HTML and view with a browser: hledger bal -D -o  a.html  &&
+         open a.html
+
+   Sorting by amount
+       With  -S/--sort-amount,  accounts with the largest (most positive) bal-
+       ances are shown first.  Eg: hledger bal expenses -MAS shows  your  big-
+       gest averaged monthly expenses first.
+
+       Revenues  and liability balances are typically negative, however, so -S
+       shows these in reverse  order.   To  work  around  this,  you  can  add
+       --invert  to flip the signs.  (Or, use one of the higher-level reports,
+       which flip the sign automatically.  Eg: hledger incomestatement  -MAS).
+
+
+   Percentages
+       With  -%/--percent, balance reports show each account's value expressed
+       as a percentage of the (column) total:
+
+              $ hledger bal expenses -Q -%
+              Balance changes in 2008:
+
+                                 || 2008Q1   2008Q2  2008Q3  2008Q4
+              ===================++=================================
+               expenses:food     ||      0   50.0 %       0       0
+               expenses:supplies ||      0   50.0 %       0       0
+              -------------------++---------------------------------
+                                 ||      0  100.0 %       0       0
+
+       Note it is not useful to calculate percentages if the amounts in a col-
+       umn  have  mixed  signs.  In this case, make a separate report for each
+       sign, eg:
+
+              $ hledger bal -% amt:`>0`
+              $ hledger bal -% amt:`<0`
+
+       Similarly, if the amounts in a column have mixed  commodities,  convert
+       them  to  one  commodity with -B, -V, -X or --value, or make a separate
+       report for each commodity:
+
+              $ hledger bal -% cur:\\$
+              $ hledger bal -% cur:EUR
+
+   Balance change, end balance
+       It's important to be clear on the meaning of the numbers shown in  bal-
+       ance reports.  Here is some terminology we use:
+
+       A  balance  change  is  the  net  amount  added to, or removed from, an
+       account during some period.
+
+       An end balance is the amount accumulated in an account as of some  date
+       (and  some  time,  but hledger doesn't store that; assume end of day in
+       your timezone).  It is the sum of previous balance changes.
+
+       We call it a historical end balance if it includes all balance  changes
+       since the account was created.  For a real world account, this means it
+       will match the "historical record", eg the balances  reported  in  your
+       bank statements or bank web UI.  (If they are correct!)
+
+       In  general,  balance  changes  are what you want to see when reviewing
+       revenues and expenses, and historical end balances are what you want to
+       see when reviewing or reconciling asset, liability and equity accounts.
+
+       balance shows balance changes by default.  To see  accurate  historical
+       end balances:
+
+       1. Initialise  account  starting  balances  with  an "opening balances"
+          transaction (a transfer from equity  to  the  account),  unless  the
+          journal covers the account's full lifetime.
+
+       2. Include all of of the account's prior postings in the report, by not
+          specifying a report start date,  or  by  using  the  -H/--historical
+          flag.  (-H causes report start date to be ignored when summing post-
+          ings.)
+
+   Balance report types
+       For more flexible reporting, there are three important option groups:
+
+       hledger balance  [CALCULATIONTYPE]  [ACCUMULATIONTYPE]  [VALUATIONTYPE]
+       ...
+
+       The  first  two  are  the  most important: calculation type selects the
+       basic calculation to perform for each table  cell,  while  accumulation
+       type says which postings should be included in each cell's calculation.
+       Typically one or both of these are selected by default,  so  you  don't
+       need  to  write  them explicitly.  A valuation type can be added if you
+       want to convert the basic report to value or cost.
+
+       Calculation type:
+       The basic calculation to perform for each table cell.  It is one of:
+
+       o --sum : sum the posting amounts (default)
+
+       o --budget : like --sum but also show a goal amount
+
+       o --valuechange : show the change in period-end historical balance val-
+         ues
+
+       Accumulation type:
+       Which  postings  should  be included in each cell's calculation.  It is
+       one of:
+
+       o --change : postings from column start to column end,  ie  within  the
+         cell's  period.   Typically  used to see revenues/expenses.  (default
+         for balance, incomestatement)
+
+       o --cumulative : postings from report start to column end, eg  to  show
+         changes accumulated since the report's start date.  Rarely used.
+
+       o --historical/-H  :  postings from journal start to column end, ie all
+         postings from account creation to the end of the cell's period.  Typ-
+         ically  used  to  see  historical  end  balances  of  assets/liabili-
+         ties/equity.  (default for  balancesheet,  balancesheetequity,  cash-
+         flow)
+
+       Valuation type:
+       Which kind of valuation, valuation date(s) and optionally a target val-
+       uation commodity to use.  It is one of:
+
+       o no valuation, show amounts in their original commodities (default)
+
+       o --value=cost[,COMM] : no valuation, show amounts converted to cost
+
+       o --value=then[,COMM] : show value at transaction dates
+
+       o --value=end[,COMM] : show value at period end date(s)  (default  with
+         --valuechange)
+
+       o --value=now[,COMM] : show value at today's date
+
+       o --value=YYYY-MM-DD[,COMM] : show value at another date
+
+       or one of their aliases: --cost/-B, --market/-V or --exchange/-X.
+
+       Most  combinations  of these options should produce reasonable reports,
+       but if you find any that seem wrong or misleading, let  us  know.   The
+       following restrictions are applied:
+
+       o --valuechange implies --value=end
+
+       o --valuechange  makes  --change  the  default  when used with the bal-
+         ancesheet/balancesheetequity commands
+
+       o --cumulative or --historical disables --row-total/-T
+
+       For reference, here is what the combinations of accumulation and valua-
+       tion show:
+
+
+       Valua-     no valuation       --value= then       --value= end       --value= YYYY-
+       tion:                                                                MM-DD /now

+
+   Useful balance reports
+       Some frequently used balance options/reports are:
+
+       o bal -M revenues expenses
+       Show  revenues/expenses  in each month.  Also available as the incomes-
+       tatement command.
+
+       o bal -M -H assets liabilities
+       Show historical asset/liability  balances  at  each  month  end.   Also
+       available as the balancesheet command.
+
+       o bal -M -H assets liabilities equity
+       Show  historical  asset/liability/equity  balances  at  each month end.
+       Also available as the balancesheetequity command.
+
+       o bal -M assets not:receivable
+       Show changes to liquid assets in each month.   Also  available  as  the
+       cashflow command.
+
+       Also:
+
+       o bal -M expenses -2 -SA
+       Show  monthly  expenses  summarised  to  depth  2 and sorted by average
+       amount.
+
+       o bal -M --budget expenses
+       Show monthly expenses and budget goals.
+
+       o bal -M --valuechange investments
+       Show monthly change in market value of investment assets.
+
+       o bal  investments  --valuechange  -D  date:lastweek  amt:'>1000'  -STA
+         [--invert]
+       Show top gainers [or losers] last week
+
+   Budget report
+       The  --budget  report  type  activates extra columns showing any budget
+       goals for each account and period.  The budget  goals  are  defined  by
+       periodic  transactions.   This is very useful for comparing planned and
+       actual income, expenses, time usage, etc.
+
+       For example, you can  take  average  monthly  expenses  in  the  common
+       expense categories to construct a minimal monthly budget:
+
+              ;; Budget
+              ~ monthly
+                income  $2000
+                expenses:food    $400
+                expenses:bus     $50
+                expenses:movies  $30
+                assets:bank:checking
+
+              ;; Two months worth of expenses
+              2017-11-01
+                income  $1950
+                expenses:food    $396
+                expenses:bus     $49
+                expenses:movies  $30
+                expenses:supplies  $20
+                assets:bank:checking
+
+              2017-12-01
+                income  $2100
+                expenses:food    $412
+                expenses:bus     $53
+                expenses:gifts   $100
+                assets:bank:checking
+
+       You can now see a monthly budget report:

+
+       o Only  accounts  with budget goals during the report period are shown,

+
+       o In each column, in square brackets after the  actual  amount,  budget
+         goal  amounts are shown, and the actual/goal percentage.  (Note: bud-
+         get goals should be in the same commodity as the actual amount.)
+
+       o All parent accounts are always shown, even in list mode.  Eg  assets,
+         assets:bank, and expenses above.
+
+       o Amounts  always include all subaccounts, budgeted or unbudgeted, even
+         in list mode.
+
+       This means that the numbers displayed will not always add up! Eg above,
+       the  expenses  actual  amount  includes the gifts and supplies transac-
+       tions, but the expenses:gifts and expenses:supplies  accounts  are  not
+       shown, as they have no budget amounts declared.
+
+       This  can  be confusing.  When you need to make things clearer, use the
+       -E/--empty flag, which will reveal all  accounts  including  unbudgeted
+       ones, giving the full picture.  Eg:
+
+              $ hledger balance -M --budget --empty

+
+   Budget report start date
+       This  might  be  a bug, but for now: when making budget reports, it's a
+       good idea to explicitly set the report's start date to the first day of
+       a  reporting  period,  because a periodic rule like ~ monthly generates
+       its transactions on the 1st of each month, and if your journal  has  no
+       regular  transactions  on  the 1st, the default report start date could
+       exclude that budget goal, which can be a little  surprising.   Eg  here
+       the default report period is just the day of 2020-01-15:
+
+              ~ monthly in 2020
+                (expenses:food)  $500
+
+              2020-01-15
+                expenses:food    $400
+                assets:checking
+
+              $ hledger bal expenses --budget

+
+       To  avoid  this,  specify  the  budget report's period, or at least the
+       start date, with -b/-e/-p/date:, to ensure it includes the budget  goal
+       transactions  (periodic  transactions)  that  you  want.  Eg, adding -b
+       2020/1/1 to the above:
+
+              $ hledger bal expenses --budget -b 2020/1/1

+
+   Nested budgets
+       You can add budgets to any account in your account hierarchy.   If  you
+       have budgets on both parent account and some of its children, then bud-
+       get(s) of the child account(s) would be added to the  budget  of  their
+       parent, much like account balances behave.
+
+       In  the  most  simple case this means that once you add a budget to any
+       account, all its parents would have budget as well.
+
+       To illustrate this, consider the following budget:
+
+              ~ monthly from 2019/01
+                  expenses:personal             $1,000.00
+                  expenses:personal:electronics    $100.00
+                  liabilities
+
+       With this, monthly budget for electronics is defined  to  be  $100  and
+       budget  for  personal expenses is an additional $1000, which implicitly
+       means that budget for both expenses:personal and expenses is $1100.
+
+       Transactions in  expenses:personal:electronics  will  be  counted  both
+       towards  its  $100 budget and $1100 of expenses:personal , and transac-
+       tions in any other subaccount of  expenses:personal  would  be  counted
+       towards only towards the budget of expenses:personal.
+
+       For example, let's consider these transactions:
+
+              ~ monthly from 2019/01
+                  expenses:personal             $1,000.00
+                  expenses:personal:electronics    $100.00
+                  liabilities
+
+              2019/01/01 Google home hub
+                  expenses:personal:electronics          $90.00
+                  liabilities                           $-90.00
+
+              2019/01/02 Phone screen protector
+                  expenses:personal:electronics:upgrades          $10.00
+                  liabilities
+
+              2019/01/02 Weekly train ticket
+                  expenses:personal:train tickets       $153.00
+                  liabilities
+
+              2019/01/03 Flowers
+                  expenses:personal          $30.00
+                  liabilities
+
+       As  you  can  see,  we have transactions in expenses:personal:electron-
+       ics:upgrades and expenses:personal:train tickets,  and  since  both  of
+       these  accounts  are  without explicitly defined budget, these transac-
+       tions would be counted towards budgets of expenses:personal:electronics
+       and expenses:personal accordingly:

+   Customising single-period balance reports
+       For single-period balance reports displayed in the terminal (only), you

+       Eg:

+              $ hledger balance --format "%20(account) %12(total)"
+                            assets          $-1

+
+       The FMT format string (plus a newline) specifies the formatting applied
+       to  each  account/balance pair.  It may contain any suitable text, with
+       data fields interpolated like so:
+
+       %[MIN][.MAX](FIELDNAME)
+
+       o MIN pads with spaces to at least this width (optional)
+
+       o MAX truncates at this width (optional)
+
+       o FIELDNAME must be enclosed in parentheses, and can be one of:
+
+         o depth_spacer - a number of spaces equal to the account's depth,  or
+           if MIN is specified, MIN * depth spaces.
+
+         o account - the account's name
+
+         o total - the account's balance/posted total, right justified
+
+       Also,  FMT  can begin with an optional prefix to control how multi-com-
+       modity amounts are rendered:
+
+       o %_ - render on multiple lines, bottom-aligned (the default)
+
+       o %^ - render on multiple lines, top-aligned
+
+       o %, - render on one line, comma-separated
+
+       There are some quirks.  Eg in one-line  mode,  %(depth_spacer)  has  no
+       effect,  instead  %(account) has indentation built in.  Experimentation
+       may be needed to get pleasing results.
+
+       Some example formats:
+
+       o %(total) - the account's total
+
+       o %-20.20(account) - the account's name, left justified, padded  to  20
+         characters and clipped at 20 characters
+
+       o %,%-50(account)   %25(total)  - account name padded to 50 characters,
+         total padded to 20 characters, with multiple commodities rendered  on
+         one line
+
+       o %20(total)   %2(depth_spacer)%-(account) - the default format for the
+         single-column balance report
+
+   balancesheet
+       balancesheet, bs
+       This command displays a balance sheet, showing historical  ending  bal-
+       ances of asset and liability accounts.  (To see equity as well, use the
+       balancesheetequity command.) Amounts are  shown  with  normal  positive
+       sign, as in conventional financial statements.
+
+       The asset and liability accounts shown are those accounts declared with
+       the Asset or Cash or Liability type, or otherwise all accounts under  a
+       top-level   asset  or  liability  account  (case  insensitive,  plurals

+       This command is a higher-level variant of the balance command, and sup-

+       It is similar to  hledger  balance  -H  assets  liabilities,  but  with
+       smarter  account  detection,  and liabilities displayed with their sign
+       flipped.
+
+       This command also supports the output  destination  and  output  format
+       options  The  output formats supported are txt, csv, html, and (experi-

+
+       The asset, liability and  equity  accounts  shown  are  those  accounts
+       declared  with  the Asset, Cash, Liability or Equity type, or otherwise
+       all accounts under a top-level asset, liability or equity account (case

+
+   cashflow
+       cashflow, cf
+       This  command  displays  a  cashflow statement, showing the inflows and
+       outflows affecting "cash" (ie, liquid) assets.  Amounts are shown  with
+       normal positive sign, as in conventional financial statements.
+
+       The  "cash"  accounts  shown  are those accounts declared with the Cash
+       type, or otherwise all accounts under a top-level asset  account  (case
+       insensitive,  plural  allowed)  which  do  not  have fixed, investment,
+       receivable or A/R in their name.

+
+   check
+       check
+       Check for various kinds of errors in your data.
+
+       hledger  provides  a  number  of  built-in error checks to help prevent
+       problems in your data.  Some of these are run  automatically;  or,  you
+       can  use this check command to run them on demand, with no output and a
+       zero exit code if all is well.  Specify their names (or  a  prefix)  as
+       argument(s).
+
+       Some examples:
+
+              hledger check      # basic checks
+              hledger check -s   # basic + strict checks
+              hledger check ordereddates payees  # basic + two other checks
+
+       Here are the checks currently available:
+
+   Basic checks
+       These checks are always run automatically, by (almost) all hledger com-
+       mands, including check:
+
+       o parseable - data files are well-formed and can be successfully parsed
+
+       o balancedwithautoconversion - all transactions are balanced, inferring
+         missing amounts where necessary, and possibly converting  commodities
+         using transaction prices or automatically-inferred transaction prices
+
+       o assertions - all balance  assertions  in  the  journal  are  passing.
+         (This check can be disabled with -I/--ignore-assertions.)
+
+   Strict checks
+       These additional checks are run when the -s/--strict (strict mode) flag
+       is used.  Or, they can be run by giving their  names  as  arguments  to
+       check:
+
+       o accounts - all account names used by transactions have been declared
+
+       o commodities - all commodity symbols used have been declared
+
+       o balancednoautoconversion  - transactions are balanced, possibly using
+         explicit transaction prices but not inferred ones
+
+   Other checks
+       These checks can be run only by giving  their  names  as  arguments  to
+       check.   They  are  more  specialised  and  not desirable for everyone,
+       therefore optional:
+
+       o ordereddates - transactions are ordered by date within each file
+
+       o payees - all payees used by transactions have been declared
+
+       o uniqueleafnames - all account leaf names are unique
+
+   Custom checks
+       A few more checks are are available as  separate  add-on  commands,  in
+       https://github.com/simonmichael/hledger/tree/master/bin:
+
+       o hledger-check-tagfiles  -  all  tag  values  containing  / (a forward
+         slash) exist as file paths
+
+       o hledger-check-fancyassertions - more complex balance  assertions  are
+         passing
+
+       You could make similar scripts to perform your own custom checks.  See:
+       Cookbook -> Scripting.
+
+   close
+       close, equity
+       Prints a "closing  balances"  transaction  and  an  "opening  balances"
+       transaction that bring account balances to and from zero, respectively.
+       These can be added to your journal file(s), eg to bring asset/liability
+       balances  forward  into  a  new  journal  file,  or  to  close out rev-
+       enues/expenses to retained earnings at the end of a period.
+
+       You can print just one of these transactions by using  the  --close  or
+       --open  flag.   You  can customise their descriptions with the --close-
+       desc and --open-desc options.
+
+       One amountless posting to "equity:opening/closing balances" is added to
+       balance  the  transactions, by default.  You can customise this account
+       name with --close-acct and --open-acct; if  you  specify  only  one  of
+       these, it will be used for both.
+
+       With --x/--explicit, the equity posting's amount will be shown.  And if
+       it involves multiple commodities, a posting for each commodity will  be
+       shown, as with the print command.
+
+       With  --interleaved, the equity postings are shown next to the postings
+       they balance, which makes troubleshooting easier.
+
+       By default, transaction prices in the journal are ignored when generat-
+       ing  the  closing/opening  transactions.   With --show-costs, this cost
+       information is preserved (balance -B reports will  be  unchanged  after
+       the transition).  Separate postings are generated for each cost in each
+       commodity.  Note this can generate very large journal entries,  if  you
+       have many foreign currency or investment transactions.
+
+   close usage
+       If you split your journal files by time (eg yearly), you will typically
+       run this command at the end of the year, and save the closing  transac-
+       tion  as last entry of the old file, and the opening transaction as the
+       first entry of the new file.  This makes the files self  contained,  so
+       that  correct balances are reported no matter which of them are loaded.
+       Ie, if you load just one file, the balances are initialised  correctly;
+       or  if  you  load several files, the redundant closing/opening transac-
+       tions cancel each other out.  (They will show up in print  or  register
+       reports;  you  can  exclude  them  with  a  query like not:desc:'(open-
+       ing|closing) balances'.)
+
+       If you're running a business, you might also use this command to "close
+       the  books"  at  the  end  of an accounting period, transferring income
+       statement account balances to retained  earnings.   (You  may  want  to
+       change the equity account name to something like "equity:retained earn-
+       ings".)
+
+       By default, the closing transaction is dated  yesterday,  the  balances
+       are  calculated  as of end of yesterday, and the opening transaction is
+       dated today.  To close on some other date, use: hledger close -e  OPEN-
+       INGDATE.   Eg,  to  close/open  on the 2018/2019 boundary, use -e 2019.
+       You can also use -p or date:PERIOD (any starting date is ignored).
+
+       Both   transactions   will   include   balance   assertions   for   the
+       closed/reopened  accounts.   You probably shouldn't use status or real-
+       ness filters (like -C or -R or status:) with this command, or the  gen-
+       erated balance assertions will depend on these flags.  Likewise, if you
+       run this command with --auto,  the  balance  assertions  will  probably
+       always require --auto.
+
+       Examples:
+
+       Carrying asset/liability balances into a new file for 2019:
+
+              $ hledger close -f 2018.journal -e 2019 assets liabilities --open
+                  # (copy/paste the output to the start of your 2019 journal file)
+              $ hledger close -f 2018.journal -e 2019 assets liabilities --close
+                  # (copy/paste the output to the end of your 2018 journal file)
+
+       Now:
+
+              $ hledger bs -f 2019.journal                   # one file - balances are correct
+              $ hledger bs -f 2018.journal -f 2019.journal   # two files - balances still correct
+              $ hledger bs -f 2018.journal not:desc:closing  # to see year-end balances, must exclude closing txn
+
+       Transactions spanning the closing date can complicate matters, breaking
+       balance assertions:
+
+              2018/12/30 a purchase made in 2018, clearing the following year
+                  expenses:food          5
+                  assets:bank:checking  -5  ; [2019/1/2]
+
+       Here's one way to resolve that:
+
+              ; in 2018.journal:
+              2018/12/30 a purchase made in 2018, clearing the following year
+                  expenses:food          5
+                  liabilities:pending
+
+              ; in 2019.journal:
+              2019/1/2 clearance of last year's pending transactions
+                  liabilities:pending    5 = 0
+                  assets:checking
+
+   codes
+       codes
+       List the codes seen in transactions, in the order parsed.
+
+       This command prints the value of each transaction's code field, in  the
+       order  transactions  were  parsed.  The transaction code is an optional
+       value written in parentheses between the date  and  description,  often
+       used to store a cheque number, order number or similar.
+
+       Transactions aren't required to have a code, and missing or empty codes
+       will not be shown by default.  With the -E/--empty flag, they  will  be
+       printed as blank lines.
+
+       You can add a query to select a subset of transactions.
+
+       Examples:
+
+              1/1 (123)
+               (a)  1
+
+              1/1 ()
+               (a)  1
+
+              1/1
+               (a)  1
+
+              1/1 (126)
+               (a)  1
+
+              $ hledger codes
+              123
+              124
+              126
+
+              $ hledger codes -E
+              123
+              124
+
+
+              126
+
+   commodities
+       commodities
+       List all commodity/currency symbols used or declared in the journal.
+
+   descriptions
+       descriptions
+       List the unique descriptions that appear in transactions.
+
+       This command lists the unique descriptions that appear in transactions,
+       in alphabetic order.  You can add a query to select a subset of  trans-
+       actions.
+
+       Example:
+
+              $ hledger descriptions
+              Store Name
+              Gas Station | Petrol
+              Person A
+
+   diff
+       diff
+       Compares  a  particular  account's transactions in two input files.  It
+       shows any transactions to this account which are in one file but not in
+       the other.
+
+       More precisely, for each posting affecting this account in either file,
+       it looks for a corresponding posting in the other file which posts  the
+       same  amount  to  the  same  account (ignoring date, description, etc.)
+       Since postings not transactions are compared, this also works when mul-
+       tiple bank transactions have been combined into a single journal entry.
+
+       This is useful eg if you have downloaded an account's transactions from
+       your  bank (eg as CSV data).  When hledger and your bank disagree about
+       the account balance, you can compare the bank data with your journal to
+       find out the cause.
+
+       Examples:
+
+              $ hledger diff -f $LEDGER_FILE -f bank.csv assets:bank:giro
+              These transactions are in the first file only:
+
+              2014/01/01 Opening Balances
+                  assets:bank:giro              EUR ...
+                  ...
+                  equity:opening balances       EUR -...
+
+              These transactions are in the second file only:
+
+   files
+       files
+       List  all  files  included in the journal.  With a REGEX argument, only
+       file names matching the regular expression (case sensitive) are  shown.
+
+   help
+       help
+       Show  the  hledger  user  manual  in one of several formats, optionally
+       positioned at a given TOPIC (if possible).  TOPIC is  any  heading,  or
+       heading  prefix,  in the manual.  Some examples: commands, print, 'auto
+       postings', periodic.
+
+       This command shows the user manual built in to  this  hledger  version.
+       It  can  be useful if the correct version of the hledger manual, or the
+       usual viewing tools, are not installed on your system.
+
+       By default it uses the best viewer it can find in $PATH, in this order:
+       info, man, $PAGER (unless a topic is specified), less, or stdout.  When
+       run non-interactively, it always uses stdout.  Or you can select a par-
+       ticular viewer with the -i (info), -m (man), or -p (pager) flags.
+
+   import
+       import
+       Read  new  transactions added to each FILE since last run, and add them
+       to the main journal file.  Or with --dry-run, just print  the  transac-
+       tions  that  would  be  added.  Or with --catchup, just mark all of the
+       FILEs' transactions as imported, without actually importing any.
+
+       Unlike other hledger commands, with import the journal file is an  out-
+       put file, and will be modified, though only by appending (existing data
+       will not be changed).  The input files are specified as  arguments,  so
+       to  import  one  or  more  CSV files to your main journal, you will run
+       hledger import bank.csv or perhaps hledger import *.csv.
+
+       Note you can import from any file format, though CSV files are the most
+       common import source, and these docs focus on that case.
+
+   Deduplication
+       As  a convenience import does deduplication while reading transactions.
+       This does not mean "ignore transactions that look the same", but rather
+       "ignore transactions that have been seen before".  This is intended for
+       when you are periodically importing  foreign  data  which  may  contain
+       already-imported  transactions.   So eg, if every day you download bank
+       CSV files containing redundant data, you can safely run hledger  import
+       bank.csv  and only new transactions will be imported.  (import is idem-
+       potent.)
+
+       Since the items being read (CSV records, eg) often  do  not  come  with
+       unique  identifiers, hledger detects new transactions by date, assuming
+       that:
+
+       1. new items always have the newest dates
+
+       2. item dates do not change across reads
+
+       3. and items with the same date  remain  in  the  same  relative  order
+          across reads.
+
+       These  are  often  true of CSV files representing transactions, or true
+       enough so that it works pretty well in practice.  1 is  important,  but
+       violations of 2 and 3 amongst the old transactions won't matter (and if
+       you import often, the new transactions will be few, so less  likely  to
+       be the ones affected).
+
+       hledger  remembers the latest date processed in each input file by sav-
+       ing a hidden ".latest" state file in the same directory.  Eg when read-
+       ing  finance/bank.csv,  it  will  look for and update the finance/.lat-
+       est.bank.csv state file.  The format is simple: one or more lines  con-
+       taining  the  same  ISO-format  date (YYYY-MM-DD), meaning "I have pro-
+       cessed transactions up to this date, and this  many  of  them  on  that
+       date." Normally you won't see or manipulate these state files yourself.
+       But if needed, you can delete them  to  reset  the  state  (making  all
+       transactions  "new"), or you can construct them to "catch up" to a cer-
+       tain date.
+
+       Note deduplication (and updating of state files) can also  be  done  by
+       print --new, but this is less often used.
+
+   Import testing
+       With  --dry-run,  the transactions that will be imported are printed to
+       the terminal, without updating your journal or state files.  The output
+       is  valid  journal  format, like the print command, so you can re-parse
+       it.  Eg, to see any importable transactions which CSV  rules  have  not
+       categorised:
+
+              $ hledger import --dry bank.csv | hledger -f- -I print unknown
+
+       or (live updating):
+
+              $ ls bank.csv* | entr bash -c 'echo ====; hledger import --dry bank.csv | hledger -f- -I print unknown'
+
+   Importing balance assignments
+       Entries  added  by import will have their posting amounts made explicit
+       (like hledger print -x).  This means that any  balance  assignments  in
+       imported  files must be evaluated; but, imported files don't get to see
+       the main file's account balances.  As a result, importing entries  with
+       balance assignments (eg from an institution that provides only balances
+       and not posting  amounts)  will  probably  generate  incorrect  posting
+       amounts.  To avoid this problem, use print instead of import:
+
+              $ hledger print IMPORTFILE [--new] >> $LEDGER_FILE
+
+       (If  you  think  import  should leave amounts implicit like print does,
+       please test it and send a pull request.)
+
+   Commodity display styles
+       Imported amounts will be formatted according to the canonical commodity
+       styles (declared or inferred) in the main journal file.
+
+   incomestatement
+       incomestatement, is
+
+       This  command  displays  an  income  statement,  showing  revenues  and
+       expenses during one or more periods.  Amounts  are  shown  with  normal
+       positive sign, as in conventional financial statements.
+
+       The revenue and expense accounts shown are those accounts declared with
+       the Revenue or Expense type, or otherwise all  accounts  under  a  top-
+       level  revenue  or income or expense account (case insensitive, plurals
+       allowed).
+
+       Example:
+
+              $ hledger incomestatement
+              Income Statement
+
+              Revenues:
+                               $-2  income
+                               $-1    gifts
+                               $-1    salary
+              --------------------
+                               $-2
+
+              Expenses:
+                                $2  expenses
+                                $1    food
+                                $1    supplies
+              --------------------
+                                $2
+
+              Total:
+              --------------------
+                                 0
+
+       This command is a higher-level variant of the balance command, and sup-
+       ports  many  of  that command's features, such as multi-period reports.
+       It is similar to hledger balance '(revenues|income)' expenses, but with
+       smarter  account  detection,  and  revenues/income displayed with their
+       sign flipped.
+
+       This command also supports the output  destination  and  output  format
+       options  The  output formats supported are txt, csv, html, and (experi-
+       mental) json.
+
+   notes
+       notes
+       List the unique notes that appear in transactions.
+
+       This command lists the unique notes that  appear  in  transactions,  in
+       alphabetic  order.   You can add a query to select a subset of transac-
+       tions.  The note is the part of the transaction description after  a  |
+       character (or if there is no |, the whole description).
+
+       Example:
+
+              $ hledger notes
+              Petrol
+              Snacks
+
+   payees
+       payees
+       List the unique payee/payer names that appear in transactions.
+
+       This  command  lists  unique payee/payer names which have been declared
+       with payee directives (--declared), used  in  transaction  descriptions
+       (--used), or both (the default).
+
+       The  payee/payer  is the part of the transaction description before a |
+       character (or if there is no |, the whole description).
+
+       You can add query arguments to select a subset of  transactions.   This
+       implies --used.
+
+       Example:
+
+              $ hledger payees
+              Store Name
+              Gas Station
+              Person A
+
+   prices
+       prices
+       Print  market  price  directives  from the journal.  With --costs, also
+       print synthetic  market  prices  based  on  transaction  prices.   With
+       --inverted-costs,  also  print  inverse  prices  based  on  transaction
+       prices.  Prices (and postings providing prices) can be  filtered  by  a
+       query.  Price amounts are always displayed with their full precision.
+
+   print
+       print
+       Show transaction journal entries, sorted by date.
+
+       The print command displays full journal entries (transactions) from the
+       journal file, sorted by date (or with --date2, by secondary date).
+
+       Amounts are shown mostly normalised to commodity display style, eg  the
+       placement  of commodity symbols will be consistent.  All of their deci-
+       mal places are shown, as in the original journal entry (with one alter-
+       ation: in some cases trailing zeroes are added.)
+
+       Amounts are shown right-aligned within each transaction (but not across
+       all transactions).
+
+       Directives and inter-transaction comments  are  not  shown,  currently.
+       This means the print command is somewhat lossy, and if you are using it
+       to reformat your journal you should take care to  also  copy  over  the
+       directives and file-level comments.
+
+       Eg:
+
+              $ hledger print
+              2008/01/01 income
+                  assets:bank:checking            $1
+                  income:salary                  $-1
+
+              2008/06/01 gift
+                  assets:bank:checking            $1
+                  income:gifts                   $-1
+
+              2008/06/02 save
+                  assets:bank:saving              $1
+                  assets:bank:checking           $-1
+
+              2008/06/03 * eat & shop
+                  expenses:food                $1
+                  expenses:supplies            $1
+                  assets:cash                 $-2
+
+              2008/12/31 * pay off
+                  liabilities:debts               $1
+                  assets:bank:checking           $-1
+
+       print's  output is usually a valid hledger journal, and you can process
+       it again with a second hledger command.  This can be useful for certain
+       kinds of search, eg:
+
+              # Show running total of food expenses paid from cash.
+              # -f- reads from stdin. -I/--ignore-assertions is sometimes needed.
+              $ hledger print assets:cash | hledger -f- -I reg expenses:food
+
+       There are some situations where print's output can become unparseable:
+
+       o Valuation  affects  posting amounts but not balance assertion or bal-
+         ance assignment amounts, potentially causing those to fail.
+
+       o Auto postings can generate postings with too many missing amounts.
+
+       Normally, the journal entry's explicit or implicit amount style is pre-
+       served.  For example, when an amount is omitted in the journal, it will
+       not appear in the output.   Similarly,  when  a  transaction  price  is
+       implied but not written, it will not appear in the output.  You can use
+       the -x/--explicit flag to  make  all  amounts  and  transaction  prices
+       explicit,  which  can  be useful for troubleshooting or for making your
+       journal more readable and robust against data entry errors.  -x is also
+       implied by using any of -B,-V,-X,--value.
+
+       Note,  -x/--explicit  will cause postings with a multi-commodity amount
+       (these can arise when a multi-commodity  transaction  has  an  implicit
+       amount)  to  be  split into multiple single-commodity postings, keeping
+       the output parseable.
+
+       With -B/--cost, amounts with transaction prices are converted  to  cost
+       using that price.  This can be used for troubleshooting.
+
+       With  -m/--match and a STR argument, print will show at most one trans-
+       action: the one one whose description is most similar to  STR,  and  is
+       most  recent.  STR should contain at least two characters.  If there is
+       no similar-enough match, no transaction will be shown.
+
+       With --new, hledger prints only transactions it has not seen on a  pre-
+       vious  run.  This uses the same deduplication system as the import com-
+       mand.  (See import's docs for details.)
+
+       This command also supports the output  destination  and  output  format
+       options  The  output formats supported are txt, csv, and (experimental)
+       json and sql.
+
+       Here's an example of print's CSV output:
+
+              $ hledger print -Ocsv
+              "txnidx","date","date2","status","code","description","comment","account","amount","commodity","credit","debit","posting-status","posting-comment"
+              "1","2008/01/01","","","","income","","assets:bank:checking","1","$","","1","",""
+              "1","2008/01/01","","","","income","","income:salary","-1","$","1","","",""
+              "2","2008/06/01","","","","gift","","assets:bank:checking","1","$","","1","",""
+              "2","2008/06/01","","","","gift","","income:gifts","-1","$","1","","",""
+              "3","2008/06/02","","","","save","","assets:bank:saving","1","$","","1","",""
+              "3","2008/06/02","","","","save","","assets:bank:checking","-1","$","1","","",""
+              "4","2008/06/03","","*","","eat & shop","","expenses:food","1","$","","1","",""
+              "4","2008/06/03","","*","","eat & shop","","expenses:supplies","1","$","","1","",""
+              "4","2008/06/03","","*","","eat & shop","","assets:cash","-2","$","2","","",""
+              "5","2008/12/31","","*","","pay off","","liabilities:debts","1","$","","1","",""
+              "5","2008/12/31","","*","","pay off","","assets:bank:checking","-1","$","1","","",""
+
+       o There is one CSV record per posting, with  the  parent  transaction's
+         fields repeated.
+
+       o The "txnidx" (transaction index) field shows which postings belong to
+         the same transaction.  (This number might change if transactions  are
+         reordered  within  the file, files are parsed/included in a different
+         order, etc.)
+
+       o The amount is separated into "commodity" (the  symbol)  and  "amount"
+         (numeric quantity) fields.
+
+       o The numeric amount is repeated in either the "credit" or "debit" col-
+         umn, for convenience.  (Those names are not accurate in the  account-
+         ing  sense;  it  just  puts negative amounts under credit and zero or
+         greater amounts under debit.)
+
+   print-unique
+       print-unique
+       Print transactions which do not reuse an already-seen description.
+
+       Example:
+
+              $ cat unique.journal
+              1/1 test
+               (acct:one)  1
+              2/2 test
+               (acct:two)  2
+              $ LEDGER_FILE=unique.journal hledger print-unique
+              (-f option not supported)
+              2015/01/01 test
+                  (acct:one)             1
+
+   register
+       register, reg
+       Show postings and their running total.
+
+       The register command displays matched postings, across all accounts, in
+       date  order,  with  their  running total or running historical balance.
+       (See also the aregister command, which shows matched transactions in  a
+       specific account.)
+
+       register normally shows line per posting, but note that multi-commodity
+       amounts will occupy multiple lines (one line per commodity).
+
+       It is typically used with a query selecting a  particular  account,  to
+       see that account's activity:
+
+              $ hledger register checking
+              2008/01/01 income               assets:bank:checking            $1           $1
+              2008/06/01 gift                 assets:bank:checking            $1           $2
+              2008/06/02 save                 assets:bank:checking           $-1           $1
+              2008/12/31 pay off              assets:bank:checking           $-1            0
+
+       With --date2, it shows and sorts by secondary date instead.
+
+       The  --historical/-H  flag  adds the balance from any undisplayed prior
+       postings to the running total.  This is useful when  you  want  to  see
+       only recent activity, with a historically accurate running balance:
+
+              $ hledger register checking -b 2008/6 --historical
+              2008/06/01 gift                 assets:bank:checking            $1           $2
+              2008/06/02 save                 assets:bank:checking           $-1           $1
+              2008/12/31 pay off              assets:bank:checking           $-1            0
+
+       The --depth option limits the amount of sub-account detail displayed.
+
+       The  --average/-A flag shows the running average posting amount instead
+       of the running total (so, the final number displayed is the average for
+       the  whole  report period).  This flag implies --empty (see below).  It
+       is affected by --historical.  It  works  best  when  showing  just  one
+       account and one commodity.
+
+       The  --related/-r  flag shows the other postings in the transactions of
+       the postings which would normally be shown.
+
+       The --invert flag negates all amounts.  For example, it can be used  on
+       an income account where amounts are normally displayed as negative num-
+       bers.  It's also useful  to  show  postings  on  the  checking  account
+       together with the related account:
+
+              $ hledger register --related --invert assets:checking
+
+       With  a  reporting  interval,  register shows summary postings, one per
+       interval, aggregating the postings to each account:
+
+              $ hledger register --monthly income
+              2008/01                 income:salary                          $-1          $-1
+              2008/06                 income:gifts                           $-1          $-2
+
+       Periods with no activity, and summary postings with a zero amount,  are
+       not shown by default; use the --empty/-E flag to see them:
+
+              $ hledger register --monthly income -E
+              2008/01                 income:salary                          $-1          $-1
+              2008/02                                                          0          $-1
+              2008/03                                                          0          $-1
+              2008/04                                                          0          $-1
+              2008/05                                                          0          $-1
+              2008/06                 income:gifts                           $-1          $-2
+              2008/07                                                          0          $-2
+              2008/08                                                          0          $-2
+              2008/09                                                          0          $-2
+              2008/10                                                          0          $-2
+              2008/11                                                          0          $-2
+              2008/12                                                          0          $-2
+
+       Often,  you'll  want  to  see  just one line per interval.  The --depth
+       option helps with this, causing subaccounts to be aggregated:
+
+              $ hledger register --monthly assets --depth 1h
+              2008/01                 assets                                  $1           $1
+              2008/06                 assets                                 $-1            0
+              2008/12                 assets                                 $-1          $-1
+
+       Note when using report intervals, if you specify start/end dates  these
+       will  be  adjusted  outward  if  necessary to contain a whole number of
+       intervals.  This ensures that the first and  last  intervals  are  full
+       length and comparable to the others in the report.
+
+   Custom register output
+       register  uses  the  full terminal width by default, except on windows.
+       You can override this by setting the COLUMNS environment variable  (not
+       a bash shell variable) or by using the --width/-w option.
+
+       The  description  and  account columns normally share the space equally
+       (about half of (width - 40) each).  You can adjust  this  by  adding  a
+       description  width  as  part  of  --width's  argument, comma-separated:
+       --width W,D .  Here's a diagram (won't display correctly in --help):
+
+              <--------------------------------- width (W) ---------------------------------->
+              date (10)  description (D)       account (W-41-D)     amount (12)   balance (12)
+              DDDDDDDDDD dddddddddddddddddddd  aaaaaaaaaaaaaaaaaaa  AAAAAAAAAAAA  AAAAAAAAAAAA
+
+       and some examples:
+
+              $ hledger reg                     # use terminal width (or 80 on windows)
+              $ hledger reg -w 100              # use width 100
+              $ COLUMNS=100 hledger reg         # set with one-time environment variable
+              $ export COLUMNS=100; hledger reg # set till session end (or window resize)
+              $ hledger reg -w 100,40           # set overall width 100, description width 40
+              $ hledger reg -w $COLUMNS,40      # use terminal width, & description width 40
+
+       This command also supports the output  destination  and  output  format
+       options  The  output formats supported are txt, csv, and (experimental)
+       json.
+
+   register-match
+       register-match
+       Print the one posting whose transaction description is closest to DESC,
+       in  the  style  of the register command.  If there are multiple equally
+       good matches, it shows the most recent.  Query  options  (options,  not
+       arguments)  can  be  used  to restrict the search space.  Helps ledger-
+       autosync detect already-seen transactions when importing.
+
+   rewrite
+       rewrite
+       Print all transactions, rewriting the postings of matched transactions.
+       For  now  the only rewrite available is adding new postings, like print
+       --auto.
+
+       This is a start at a generic rewriter of transaction entries.  It reads
+       the  default  journal and prints the transactions, like print, but adds
+       one or more specified postings to any transactions matching QUERY.  The
+       posting  amounts can be fixed, or a multiplier of the existing transac-
+       tion's first posting amount.
+
+       Examples:
+
+              $ hledger-rewrite.hs ^income --add-posting '(liabilities:tax)  *.33  ; income tax' --add-posting '(reserve:gifts)  $100'
+              $ hledger-rewrite.hs expenses:gifts --add-posting '(reserve:gifts)  *-1"'
+              $ hledger-rewrite.hs -f rewrites.hledger
+
+       rewrites.hledger may consist of entries like:
+

+
+       Argument  for  --add-posting  option  is a usual posting of transaction
+       with an exception for amount specification.  More  precisely,  you  can

+       factor for an amount  of  original  matched  posting.   If  the  amount
+       includes  a  commodity  name, the new posting amount will be in the new
+       commodity; otherwise, it will be in the matched posting  amount's  com-
+       modity.

+   Re-write rules in a file
+       During  the  run  this  tool will execute so called "Automated Transac-
+       tions" found in any journal it process.  I.e instead of specifying this
+       operations in command line you can put them in a journal file.
+
+              $ rewrite-rules.journal
+
+       Make contents look like this:
+
+              = ^income
+                  (liabilities:tax)  *.33
+
+              = expenses:gifts
+                  budget:gifts  *-1
+                  assets:budget  *1
+
+       Note  that '=' (equality symbol) that is used instead of date in trans-
+       actions you usually write.  It indicates the query by which you want to
+       match the posting to add new ones.
+
+              $ hledger rewrite -- -f input.journal -f rewrite-rules.journal > rewritten-tidy-output.journal
+
+       This is something similar to the commands pipeline:
+
+              $ hledger rewrite -- -f input.journal '^income' --add-posting '(liabilities:tax)  *.33' \
+                | hledger rewrite -- -f - expenses:gifts      --add-posting 'budget:gifts  *-1'       \
+                                                              --add-posting 'assets:budget  *1'       \
+                > rewritten-tidy-output.journal
+
+       It  is  important  to understand that relative order of such entries in
+       journal is important.  You can re-use result of previously added  post-
+       ings.
+
+   Diff output format
+       To  use  this tool for batch modification of your journal files you may
+       find useful output in form of unified diff.

+   rewrite vs. print --auto
+       This command predates print --auto, and currently does  much  the  same
+       thing, but with these differences:
+
+       o with  multiple files, rewrite lets rules in any file affect all other
+         files.  print --auto uses standard directive  scoping;  rules  affect
+         only child files.
+
+       o rewrite's  query  limits which transactions can be rewritten; all are
+         printed.  print --auto's query limits which transactions are printed.
+
+       o rewrite  applies  rules  specified on command line or in the journal.
+         print --auto applies rules specified in the journal.
+
+   roi
+       roi
+       Shows the time-weighted (TWR) and money-weighted (IRR) rate  of  return
+       on your investments.
+
+       At  a  minimum,  you  need  to  supply  a query (which could be just an
+       account name) to select your  investment(s)  with  --inv,  and  another
+       query to identify your profit and loss transactions with --pnl.
+
+       If  you do not record changes in the value of your investment manually,
+       or do not require computation  of  time-weighted  return  (TWR),  --pnl
+       could be an empty query (--pnl "" or --pnl STR where STR does not match
+       any of your accounts).
+
+       This command will compute and display the internalized rate  of  return
+       (IRR)  and  time-weighted rate of return (TWR) for your investments for
+       the time period requested.  Both rates of return are annualized  before
+       display, regardless of the length of reporting interval.
+
+       Price  directives  will be taken into account if you supply appropriate
+       --cost or --value flags (see VALUATION).
+
+       Note, in some cases this report can fail, for these reasons:
+
+       o Error (NotBracketed): No solution for Internal Rate of Return  (IRR).
+         Possible  causes:  IRR  is  huge  (>1000000%),  balance of investment
+         becomes negative at some point in time.
+
+       o Error (SearchFailed): Failed to find solution for  Internal  Rate  of
+         Return (IRR).  Either search does not converge to a solution, or con-
+         verges too slowly.
+
+       Examples:
+
+       o Using  roi  to  compute  total  return  of  investment   in   stocks:

+
+       o Cookbook -> Return on Investment
+
+   Spaces and special characters in --inv and --pnl
+       Note that --inv and --pnl's argument is a query, and queries could have
+       several space-separated terms (see QUERIES).
+
+       To  indicate  that  all search terms form single command-line argument,
+       you will need to put them in quotes (see Special characters):
+
+              $ hledger roi --inv 'term1 term2 term3 ...'
+
+       If any query terms contain spaces themselves, you will  need  an  extra
+       level of nested quoting, eg:
+
+              $ hledger roi --inv="'Assets:Test 1'" --pnl="'Equity:Unrealized Profit and Loss'"
+
+   Semantics of --inv and --pnl
+       Query  supplied to --inv has to match all transactions that are related
+       to your investment.  Transactions not matching --inv will be ignored.
+
+       In these transactions, ROI will conside postings that match --inv to be
+       "investment  postings"  and other postings (not matching --inv) will be
+       sorted into two categories: "cash flow" and "profit and loss",  as  ROI
+       needs  to know which part of the investment value is your contributions
+       and which is due to the return on investment.
+
+       o "Cash flow" is depositing or withdrawing  money,  buying  or  selling
+         assets, or otherwise converting between your investment commodity and
+         any other commodity.  Example:
+
+                2019-01-01 Investing in Snake Oil
+                  assets:cash          -$100
+                  investment:snake oil
+
+                2020-01-01 Selling my Snake Oil
+                  assets:cash           $10
+                  investment:snake oil  = 0
+
+       o "Profit and loss" is change in the value of your investment:
+
+                2019-06-01 Snake Oil falls in value
+                  investment:snake oil  = $57
+                  equity:unrealized profit or loss
+
+       All non-investment postings are assumed to be "cash flow", unless  they
+       match  --pnl query.  Changes in value of your investment due to "profit
+       and loss" postings will  be  considered  as  part  of  your  investment
+       return.
+
+       Example:  if you use --inv snake --pnl equity:unrealized, then postings
+       in the example below would be classifed as:
+
+              2019-01-01 Snake Oil #1
+                assets:cash          -$100   ; cash flow posting
+                investment:snake oil         ; investment posting
+
+              2019-03-01 Snake Oil #2
+                equity:unrealized pnl  -$100 ; profit and loss posting
+                snake oil                    ; investment posting
+
+              2019-07-01 Snake Oil #3
+                equity:unrealized pnl        ; profit and loss posting
+                cash          -$100          ; cash flow posting
+                snake oil     $50            ; investment posting
+
+   IRR and TWR explained
+       "ROI" stands for "return on investment".  Traditionally this  was  com-
+       puted  as a difference between current value of investment and its ini-
+       tial value, expressed in percentage of the initial value.
+
+       However, this approach is only practical in simple cases, where invest-
+       ments  receives  no  in-flows  or out-flows of money, and where rate of
+       growth is fixed over time.  For more complex scenarios you need differ-
+       ent  ways to compute rate of return, and this command implements two of
+       them: IRR and TWR.
+
+       Internal rate of return, or "IRR" (also called "money-weighted rate  of
+       return")   takes  into  account  effects  of  in-flows  and  out-flows.
+       Naively, if you are withdrawing from your investment, your future gains
+       would  be smaller (in absolute numbers), and will be a smaller percent-
+       age of your initial investment, and if you are adding to  your  invest-
+       ment,  you will receive bigger absolute gains (but probably at the same
+       rate of return).  IRR is a way to  compute  rate  of  return  for  each
+       period between in-flow or out-flow of money, and then combine them in a
+       way that gives you a compound annual rate of return that investment  is
+       expected to generate.
+
+       As  mentioned before, in-flows and out-flows would be any cash that you
+       personally put in or withdraw, and for the "roi" command, these are the
+       postings  that  match  the query in the--inv argument and NOT match the
+       query in the--pnl argument.
+
+       If you manually record changes in  the  value  of  your  investment  as
+       transactions  that  balance them against "profit and loss" (or "unreal-
+       ized gains") account or use price directives, then in order for IRR  to
+       compute  the  precise effect of your in-flows and out-flows on the rate
+       of return, you will need to record the value of your investement on  or
+       close to the days when in- or out-flows occur.
+
+       In  technical  terms,  IRR uses the same approach as computation of net
+       present value, and tries to find a discount rate that makes net present
+       value of all the cash flows of your investment to add up to zero.  This
+       could be hard to wrap your head around, especially if you haven't  done
+       discounted cash flow analysis before.  Implementation of IRR in hledger
+       should produce results that match the XIRR formula in Excel.
+
+       Second way to compute rate of return that  roi  command  implements  is
+       called "time-weighted rate of return" or "TWR".  Like IRR, it will also
+       break the history of your investment  into  periods  between  in-flows,
+       out-flows  and value changes, to compute rate of return per each period
+       and then a compound rate of return.  However, internal workings of  TWR
+       are quite different.
+
+       TWR  represents  your  investment as an imaginary "unit fund" where in-
+       flows/ out-flows lead to buying or selling "units" of  your  investment
+       and changes in its value change the value of "investment unit".  Change
+       in "unit price" over the reporting period gives you rate of  return  of
+       your investment.

+   stats
+       stats
+       Show some journal statistics.
+
+       The  stats  command displays summary information for the whole journal,
+       or a matched part of it.  With a reporting interval, it shows a  report
+       for each report period.
+
+       Example:
+
+              $ hledger stats
+              Main journal file        : /src/hledger/examples/sample.journal
+              Included journal files   :
+              Transactions span        : 2008-01-01 to 2009-01-01 (366 days)
+              Last transaction         : 2008-12-31 (2333 days ago)
+              Transactions             : 5 (0.0 per day)
+              Transactions last 30 days: 0 (0.0 per day)
+              Transactions last 7 days : 0 (0.0 per day)
+              Payees/descriptions      : 5
+              Accounts                 : 8 (depth 3)
+              Commodities              : 1 ($)
+              Market prices            : 12 ($)
+
+       This  command also supports output destination and output format selec-
+       tion.
+
+   tags
+       tags
+       List the unique tag names used in the journal.  With a  TAGREGEX  argu-
+       ment, only tag names matching the regular expression (case insensitive)
+       are shown.  With QUERY arguments, only transactions matching the  query
+       are considered.
+
+       With the --values flag, the tags' unique values are listed instead.
+
+       With  --parsed flag, all tags or values are shown in the order they are
+       parsed from the input data, including duplicates.
+
+       With -E/--empty, any blank/empty values will also be  shown,  otherwise
+       they are omitted.
+
+   test
+       test
+       Run built-in unit tests.
+
+       This  command  runs the unit tests built in to hledger and hledger-lib,
+       printing the results on stdout.  If any test fails, the exit code  will
+       be non-zero.
+
+       This  is  mainly used by hledger developers, but you can also use it to
+       sanity-check the installed hledger executable on  your  platform.   All
+       tests  are  expected to pass - if you ever see a failure, please report
+       as a bug!
+
+       This command also accepts tasty test runner options, written after a --
+       (double hyphen).  Eg to run only the tests in Hledger.Data.Amount, with
+       ANSI colour codes disabled:
+
+              $ hledger test -- -pData.Amount --color=never
+
+       For help on these, see  https://github.com/feuerbach/tasty#options  (--
+       --help currently doesn't show them).
+
+   About add-on commands
+       Add-on commands are programs or scripts in your PATH
+
+       o whose name starts with hledger-
+
+       o whose  name  ends  with  a recognised file extension: .bat,.com,.exe,
+         .hs,.lhs,.pl,.py,.rb,.rkt,.sh or none
+
+       o and (on unix, mac) which are executable by the current user.
+
+       Add-ons are a relatively easy way to add local features  or  experiment
+       with  new  ideas.   They  can  be  written in any language, but haskell
+       scripts have a big advantage: they can use  the  same  hledger  library
+       functions  that built-in commands use for command-line options, parsing
+       and reporting.  Some experimental/example add-on scripts can  be  found
+       in the hledger repo's bin/ directory.
+
+       Note in a hledger command line, add-on command flags must have a double
+       dash (--) preceding them.  Eg you must write:
+
+              $ hledger web -- --serve
+
+       and not:
+
+              $ hledger web --serve
+
+       (because the --serve flag belongs to hledger-web, not hledger).
+
+       The -h/--help and --version flags don't require --.
+
+       If you have any trouble with this, remember you can always run the add-
+       on program directly, eg:
+
+              $ hledger-web --serve
+
+JOURNAL FORMAT
+       hledger's default file format, representing a General Journal.
+
+       hledger's  usual  data  source  is a plain text file containing journal
+       entries in hledger journal format.  This  file  represents  a  standard
+       accounting  general  journal.  I use file names ending in .journal, but
+       that's not required.  The journal file contains a number of transaction
+       entries, each describing a transfer of money (or any commodity) between
+       two or more named accounts, in a simple format readable by both hledger
+       and humans.
+
+       hledger's  journal  format  is a compatible subset, mostly, of ledger's
+       journal format, so hledger can  work  with  compatible  ledger  journal
+       files  as  well.   It's  safe,  and encouraged, to run both hledger and
+       ledger on the same journal file, eg to validate the results you're get-
+       ting.
+
+       You can use hledger without learning any more about this file; just use
+       the add or web or import commands to create and update it.
+
+       Many users, though, edit the journal file with a text editor, and track
+       changes  with a version control system such as git.  Editor addons such
+       as ledger-mode or hledger-mode  for  Emacs,  vim-ledger  for  Vim,  and
+       hledger-vscode for Visual Studio Code, make this easier, adding colour,
+       formatting, tab completion, and useful commands.  See Editor configura-
+       tion at hledger.org for the full list.
+
+       Here's  a  description  of  each part of the file format (and hledger's
+       data model).  These are mostly in the order you'll  use  them,  but  in
+       some  cases related concepts have been grouped together for easy refer-
+       ence, or linked before they are introduced, so feel free to  skip  over
+       anything that looks unnecessary right now.
+
+   Transactions
+       Transactions  are the main unit of information in a journal file.  They
+       represent events, typically a movement of some quantity of  commodities
+       between two or more named accounts.
+
+       Each  transaction is recorded as a journal entry, beginning with a sim-
+       ple date in column 0.  This can be followed by  any  of  the  following
+       optional fields, separated by spaces:
+
+       o a status character (empty, !, or *)
+
+       o a code (any short number or text, enclosed in parentheses)
+
+       o a description (any remaining text until end of line or a semicolon)
+
+       o a  comment  (any  remaining  text  following a semicolon until end of
+         line, and any following indented lines beginning with a semicolon)
+
+       o 0 or more indented posting lines, describing what was transferred and
+         the  accounts  involved (indented comment lines are also allowed, but
+         not blank lines or non-indented lines).
+
+       Here's a simple journal file containing one transaction:
+
+              2008/01/01 income
+                assets:bank:checking   $1
+                income:salary         $-1

+   Dates
+   Simple dates
+       Dates in the journal  file  use  simple  dates  format:  YYYY-MM-DD  or
+       YYYY/MM/DD or YYYY.MM.DD, with leading zeros optional.  The year may be
+       omitted, in which case it will be inferred from the context:  the  cur-
+       rent  transaction,  the default year set with a default year directive,
+       or  the  current  date  when  the  command  is  run.   Some   examples:
+       2010-01-31, 2010/01/31, 2010.1.31, 1/31.
+
+       (The  UI  also accepts simple dates, as well as the more flexible smart
+       dates documented in the hledger manual.)
+
+   Secondary dates
+       Real-life transactions sometimes involve more than one date  -  eg  the
+       date you write a cheque, and the date it clears in your bank.  When you
+       want to model this, for more accurate daily balances, you  can  specify
+       individual posting dates.
+
+       Or,  you can use the older secondary date feature (Ledger calls it aux-
+       iliary date or effective date).  Note: we support this for  compatibil-
+       ity,  but  I usually recommend avoiding this feature; posting dates are
+       almost always clearer and simpler.
+
+       A secondary date is written after the primary date, following an equals
+       sign.   If  the  year  is  omitted, the primary date's year is assumed.
+       When running reports, the primary (left) date is used by  default,  but
+       with  the  --date2  flag  (or --aux-date or --effective), the secondary
+       (right) date will be used instead.
+
+       The meaning of secondary dates is up to you, but it's best to follow  a
+       consistent  rule.   Eg "primary = the bank's clearing date, secondary =
+       date the transaction was initiated, if different", as shown here:
+
+              2010/2/23=2/19 movie ticket
+                expenses:cinema                   $10
+                assets:checking
+
+              $ hledger register checking
+              2010-02-23 movie ticket         assets:checking                $-10         $-10
+
+              $ hledger register checking --date2
+              2010-02-19 movie ticket         assets:checking                $-10         $-10
+
+   Posting dates
+       You can give individual postings a different  date  from  their  parent
+       transaction,  by  adding a posting comment containing a tag (see below)
+       like date:DATE.  This is probably the best way to control posting dates
+       precisely.   Eg  in  this  example  the  expense  should  appear in May
+       reports, and the deduction from checking should be reported on 6/1  for
+       easy bank reconciliation:
+
+              2015/5/30
+                  expenses:food     $10  ; food purchased on saturday 5/30
+                  assets:checking        ; bank cleared it on monday, date:6/1
+
+              $ hledger -f t.j register food
+              2015-05-30                      expenses:food                  $10           $10
+
+              $ hledger -f t.j register checking
+              2015-06-01                      assets:checking               $-10          $-10
+
+       DATE  should be a simple date; if the year is not specified it will use
+       the year of the transaction's date.  You can  set  the  secondary  date
+       similarly,  with  date2:DATE2.   The  date:  or date2: tags must have a
+       valid simple date value if they are present, eg a  date:  tag  with  no
+       value is not allowed.
+
+       Ledger's earlier, more compact bracketed date syntax is also supported:
+       [DATE], [DATE=DATE2] or [=DATE2].  hledger will attempt  to  parse  any
+       square-bracketed sequence of the 0123456789/-.= characters in this way.
+       With this syntax, DATE infers its year from the transaction  and  DATE2
+       infers its year from DATE.
+
+   Status
+       Transactions,  or  individual postings within a transaction, can have a
+       status mark,  which  is  a  single  character  before  the  transaction
+       description  or  posting  account  name,  separated from it by a space,
+       indicating one of three statuses:
+
+
+       mark     status
+       ------------------
+                unmarked
+       !        pending
+       *        cleared
+
+       When reporting, you  can  filter  by  status  with  the  -U/--unmarked,
+       -P/--pending,  and  -C/--cleared  flags;  or the status:, status:!, and
+       status:* queries; or the U, P, C keys in hledger-ui.
+
+       Note, in Ledger and in older versions of hledger, the "unmarked"  state
+       is  called  "uncleared".   As  of  hledger  1.3  we  have renamed it to
+       unmarked for clarity.
+
+       To replicate Ledger and old hledger's behaviour of also matching  pend-
+       ing, combine -U and -P.
+
+       Status  marks  are optional, but can be helpful eg for reconciling with
+       real-world accounts.  Some editor modes provide highlighting and short-
+       cuts  for working with status.  Eg in Emacs ledger-mode, you can toggle
+       transaction status with C-c C-e, or posting status with C-c C-c.
+
+       What "uncleared", "pending", and "cleared" actually mean is up to  you.
+       Here's one suggestion:
+
+
+       status       meaning
+       --------------------------------------------------------------------------
+       uncleared    recorded but not yet reconciled; needs review
+       pending      tentatively reconciled (if needed, eg during a big reconcil-
+                    iation)
+       cleared      complete, reconciled as far as possible, and considered cor-
+                    rect
+
+       With  this scheme, you would use -PC to see the current balance at your
+       bank, -U to see things which will probably hit  your  bank  soon  (like
+       uncashed checks), and no flags to see the most up-to-date state of your
+       finances.
+
+   Code
+       After the status mark, but before the description, you  can  optionally
+       write  a  transaction  "code", enclosed in parentheses.  This is a good
+       place to record a check number, or some other important transaction  id
+       or reference number.
+
+   Description
+       A  transaction's description is the rest of the line following the date
+       and status mark (or until a  comment  begins).   Sometimes  called  the
+       "narration" in traditional bookkeeping, it can be used for whatever you
+       wish, or left blank.  Transaction descriptions can be  queried,  unlike
+       comments.
+
+   Payee and note
+       You can optionally include a | (pipe) character in descriptions to sub-
+       divide the description into separate fields for payee/payer name on the
+       left  (up  to  the  first  |) and an additional note field on the right
+       (after the first |).  This may be worthwhile if you  need  to  do  more
+       precise querying and pivoting by payee or by note.
+
+   Comments
+       Lines in the journal beginning with a semicolon (;) or hash (#) or star
+       (*) are comments, and will be ignored.  (Star comments  cause  org-mode
+       nodes  to  be  ignored, allowing emacs users to fold and navigate their
+       journals with org-mode or orgstruct-mode.)
+
+       You can attach comments to a transaction  by  writing  them  after  the
+       description  and/or  indented  on the following lines (before the post-
+       ings).  Similarly, you can attach comments to an individual posting  by
+       writing  them  after the amount and/or indented on the following lines.
+       Transaction and posting comments must begin with a semicolon (;).
+
+       Some examples:
+
+              # a file comment
+              ; another file comment
+              * also a file comment, useful in org/orgstruct mode
+
+              comment
+              A multiline file comment, which continues
+              until a line containing just "end comment"
+              (or end of file).
+              end comment
+
+              2012/5/14 something  ; a transaction comment
+                  ; the transaction comment, continued
+                  posting1  1  ; a comment for posting 1
+                  posting2
+                  ; a comment for posting 2
+                  ; another comment line for posting 2
+              ; a file comment (because not indented)
+
+       You can also comment larger regions of a file  using  comment  and  end
+       comment directives.
+
+   Tags
+       Tags  are  a  way  to add extra labels or labelled data to postings and
+       transactions, which you can then search or pivot on.
+
+       A simple tag is a word (which may contain hyphens) followed by  a  full
+       colon, written inside a transaction or posting comment line:
+
+              2017/1/16 bought groceries  ; sometag:
+
+       Tags  can  have  a  value, which is the text after the colon, up to the
+       next comma or end of line, with leading/trailing whitespace removed:
+
+                  expenses:food    $10 ; a-posting-tag: the tag value
+
+       Note this means hledger's tag values can not  contain  commas  or  new-
+       lines.  Ending at commas means you can write multiple short tags on one
+       line, comma separated:
+
+                  assets:checking  ; a comment containing tag1:, tag2: some value ...
+
+       Here,
+
+       o "a comment containing" is just comment text, not a tag
+
+       o "tag1" is a tag with no value
+
+       o "tag2" is another tag, whose value is "some value ..."
+
+       Tags in a transaction comment affect the transaction  and  all  of  its
+       postings,  while  tags  in  a posting comment affect only that posting.
+       For example, the following transaction has three tags (A, TAG2,  third-
+       tag) and the posting has four (those plus posting-tag):
+
+              1/1 a transaction  ; A:, TAG2:
+                  ; third-tag: a third transaction tag, <- with a value
+                  (a)  $1  ; posting-tag:
+
+       Tags  are  like  Ledger's metadata feature, except hledger's tag values
+       are simple strings.
+
+   Postings
+       A posting is an addition of some amount to, or removal of  some  amount
+       from,  an account.  Each posting line begins with at least one space or
+       tab (2 or 4 spaces is common), followed by:
+
+       o (optional) a status character (empty, !, or *), followed by a space
+
+       o (required) an account name (any text,  optionally  containing  single
+         spaces, until end of line or a double space)
+
+       o (optional) two or more spaces or tabs followed by an amount.
+
+       Positive  amounts  are being added to the account, negative amounts are
+       being removed.
+
+       The amounts within a transaction must always sum up to zero.  As a con-
+       venience,  one  amount  may be left blank; it will be inferred so as to
+       balance the transaction.
+
+       Be sure to note the unusual two-space delimiter  between  account  name
+       and  amount.  This makes it easy to write account names containing spa-
+       ces.  But if you accidentally leave only one space (or tab) before  the
+       amount, the amount will be considered part of the account name.
+
+   Virtual postings
+       A posting with a parenthesised account name is called a virtual posting
+       or unbalanced posting, which means it is exempt  from  the  usual  rule
+       that a transaction's postings must balance add up to zero.
+
+       This  is  not  part  of double entry accounting, so you might choose to
+       avoid this feature.  Or you can use it sparingly  for  certain  special
+       cases  where  it can be convenient.  Eg, you could set opening balances
+       without using a balancing equity account:
+
+              1/1 opening balances
+                (assets:checking)   $1000
+                (assets:savings)    $2000
+
+       A posting with a bracketed account name is called  a  balanced  virtual
+       posting.  The balanced virtual postings in a transaction must add up to
+       zero (separately from other postings).  Eg:
+
+              1/1 buy food with cash, update budget envelope subaccounts, & something else
+                assets:cash                    $-10 ; <- these balance
+                expenses:food                    $7 ; <-
+                expenses:food                    $3 ; <-
+                [assets:checking:budget:food]  $-10    ; <- and these balance
+                [assets:checking:available]     $10    ; <-
+                (something:else)                 $5       ; <- not required to balance
+
+       Ordinary non-parenthesised,  non-bracketed  postings  are  called  real
+       postings.   You  can  exclude  virtual  postings  from reports with the
+       -R/--real flag or real:1 query.
+
+   Account names
+       Account names typically have several parts separated by a  full  colon,
+       from  which hledger derives a hierarchical chart of accounts.  They can
+       be anything you like, but in finance there are traditionally five  top-
+       level accounts: assets, liabilities, revenue, expenses, and equity.
+
+       Account  names  may  contain single spaces, eg: assets:accounts receiv-
+       able.  Because of this, they must always be followed  by  two  or  more
+       spaces (or newline).
+
+       Account names can be aliased.
+
+   Amounts
+       After  the  account  name,  there  is  usually  an amount.  (Important:
+       between account name and amount, there must be two or more spaces.)
+
+       hledger's amount format is flexible, supporting  several  international
+       formats.   Here  are  some examples.  Amounts have a number (the "quan-
+       tity"):
+
+              1
+
+       ..and usually a currency symbol or commodity name (more on this below),
+       to  the  left  or  right  of the quantity, with or without a separating
+       space:
+
+              $1
+              4000 AAPL
+              3 "green apples"
+
+       Amounts can be preceded by a minus sign (or a plus sign, though plus is
+       the  default), The sign can be written before or after a left-side com-
+       modity symbol:
+
+              -$1
+              $-1
+
+       One or more spaces between the sign and the number are acceptable  when
+       parsing (but they won't be displayed in output):
+
+              + $1
+              $-      1
+
+       Scientific E notation is allowed:
+
+              1E-6
+              EUR 1E3
+
+   Decimal marks, digit group marks
+       A decimal mark can be written as a period or a comma:
+
+              1.23
+              1,23456780000009
+
+       In  the integer part of the quantity (left of the decimal mark), groups
+       of digits can optionally be separated by  a  "digit  group  mark"  -  a
+       space, comma, or period (different from the decimal mark):
+
+                   $1,000,000.00
+                EUR 2.000.000,00
+              INR 9,99,99,999.00
+                    1 000 000.9455
+
+       Note, a number containing a single digit group mark and no decimal mark
+       is ambiguous.  Are these digit group marks or decimal marks ?
+
+              1,000
+              1.000
+
+       If you don't tell it otherwise, hledger will assume both of  the  above
+       are decimal marks, parsing both numbers as 1.  To prevent confusion and
+       undetected typos, we recommend adding commodity directives at  the  top
+       of  your  journal  file  to  explicitly  declare  the decimal mark (and
+       optionally a digit group mark) for each commodity.  Read  on  for  more
+       about this.
+
+   Commodity
+       Amounts  in  hledger  have both a "quantity", which is a signed decimal
+       number, and a "commodity", which is a currency symbol, stock ticker, or
+       any word or phrase describing something you are tracking.
+
+       If the commodity name contains non-letters (spaces, numbers, or punctu-
+       ation), you must always write it inside double quotes ("green  apples",
+       "ABC123").
+
+       If  you  write just a bare number, that too will have a commodity, with
+       name ""; we call that the "no-symbol commodity".
+
+       Actually, hledger combines these  single-commodity  amounts  into  more
+       powerful  multi-commodity amounts, which are what it works with most of
+       the time.  A multi-commodity amount could be, eg: 1 USD, 2  EUR,  3.456
+       TSLA.   In  practice,  you  will  only  see  multi-commodity amounts in
+       hledger's output; you can't write them directly in the journal file.
+
+       (If you are writing scripts or working with hledger's internals,  these
+       are the Amount and MixedAmount types.)
+
+   Commodity directives
+       You can add commodity directives to the journal, preferably at the top,
+       to declare your commodities and help with number  parsing  (see  above)
+       and  display  (see  below).  These are optional, but recommended.  They
+       are described in more detail in JOURNAL FORMAT  ->  Declaring  commodi-
+       ties.  Here's a quick example:
+
+              # number format and display style for $, EUR, INR and the no-symbol commodity:
+              commodity $1,000.00
+              commodity EUR 1.000,00
+              commodity INR 9,99,99,999.00
+              commodity 1 000 000.9455
+
+
+   Commodity display style
+       For the amounts in each commodity, hledger chooses a consistent display
+       style to use in most reports.   (Exceptions:  price  amounts,  and  all
+       amounts displayed by the print command, are displayed with all of their
+       decimal digits visible.)
+
+       A commodity's display style is inferred as follows.
+
+       First, if a default commodity is declared with D,  this  commodity  and
+       its style is applied to any no-symbol amounts in the journal.
+
+       Then  each  commodity's style is inferred from one of the following, in
+       order of preference:
+
+       o The commodity directive for that commodity (including  the  no-symbol
+         commodity), if any.
+
+       o The  amounts  in  that  commodity seen in the journal's transactions.
+         (Posting amounts only; prices and periodic or auto rules are ignored,
+         currently.)
+
+       o The  built-in fallback style, which looks like this: $1000.00.  (Sym-
+         bol on the left, period decimal mark, two decimal places.)
+
+       A style is inferred from journal amounts as follows:
+
+       o Use the general style (decimal mark, symbol placement) of  the  first
+         amount
+
+       o Use  the  first-seen digit group style (digit group mark, digit group
+         sizes), if any
+
+       o Use the maximum number of decimal places of all.
+
+       Transaction price amounts don't  affect  the  commodity  display  style
+       directly,  but  occasionally they can do so indirectly (eg when a post-
+       ing's amount is inferred using a transaction price).  If you find  this
+       causing problems, use a commodity directive to fix the display style.
+
+       To  summarise:  each  commodity's amounts will be normalised to (a) the
+       style declared by a commodity directive, or (b) the style of the  first
+       posting  amount  in  the journal, with the first-seen digit group style
+       and the maximum-seen number of decimal places.  So if your reports  are
+       showing  amounts  in  a  way  you  don't like, eg with too many decimal
+       places, use a commodity directive.  Some examples:

+
+   Rounding
+       Amounts are stored internally as decimal numbers with up to 255 decimal
+       places,  and  displayed  with the number of decimal places specified by
+       the commodity display style.  Note, hledger uses banker's rounding:  it
+       rounds  to  the nearest even number, eg 0.5 displayed with zero decimal
+       places is "0").  (Guaranteed since hledger 1.17.1;  in  older  versions
+       this could vary if hledger was built with Decimal < 0.5.1.)
+
+   Transaction prices
+       Within a transaction, you can note an amount's price in another commod-
+       ity.  This can be used to document the cost (in a purchase) or  selling
+       price  (in  a  sale).   For  example,  transaction prices are useful to
+       record purchases of a foreign currency.  Note  transaction  prices  are
+       fixed at the time of the transaction, and do not change over time.  See
+       also market prices, which represent prevailing exchange rates on a cer-
+       tain date.
+
+       There are several ways to record a transaction price:
+
+       1. Write the price per unit, as @ UNITPRICE after the amount:
+
+                  2009/1/1
+                    assets:euros     EUR100 @ $1.35  ; one hundred euros purchased at $1.35 each
+                    assets:dollars                 ; balancing amount is -$135.00
+
+       2. Write the total price, as @@ TOTALPRICE after the amount:
+
+                  2009/1/1
+                    assets:euros     EUR100 @@ $135  ; one hundred euros purchased at $135 for the lot
+                    assets:dollars
+
+       3. Specify amounts for all postings, using exactly two commodities, and
+          let hledger infer the price that balances the transaction:
+
+                  2009/1/1
+                    assets:euros     EUR100          ; one hundred euros purchased
+                    assets:dollars  $-135          ; for $135
+
+       4. Like 1, but the @ is parenthesised, i.e.  (@); this is for  compati-
+          bility  with Ledger journals (Virtual posting costs), and is equiva-
+          lent to 1 in hledger.
+
+       5. Like 2, but as in 4 the @@ is parenthesised, i.e.  (@@); in hledger,
+          this is equivalent to 2.
+
+       Use  the -B/--cost flag to convert amounts to their transaction price's
+       commodity, if any.  (mnemonic: "B" is from "cost Basis", as in Ledger).
+       Eg here is how -B affects the balance report for the example above:
+
+              $ hledger bal -N --flat
+                             $-135  assets:dollars
+                              EUR100  assets:euros
+              $ hledger bal -N --flat -B
+                             $-135  assets:dollars
+                              $135  assets:euros    # <- the euros' cost
+
+       Note  -B is sensitive to the order of postings when a transaction price
+       is inferred: the inferred price will be in the commodity  of  the  last
+       amount.  So if example 3's postings are reversed, while the transaction
+       is equivalent, -B shows something different:
+
+              2009/1/1
+                assets:dollars  $-135              ; 135 dollars sold
+                assets:euros     EUR100              ; for 100 euros
+
+              $ hledger bal -N --flat -B
+                             EUR-100  assets:dollars  # <- the dollars' selling price
+                              EUR100  assets:euros
+
+   Lot prices, lot dates
+       Ledger allows another kind of price, lot price (four  variants:  {UNIT-
+       PRICE},   {{TOTALPRICE}},   {=FIXEDUNITPRICE},   {{=FIXEDTOTALPRICE}}),
+       and/or a lot date ([DATE]) to be specified.  These are normally used to
+       select  a  lot when selling investments.  hledger will parse these, for
+       compatibility with Ledger journals,  but  currently  ignores  them.   A
+       transaction  price,  lot price and/or lot date may appear in any order,
+       after the posting amount and before the balance assertion if any.
+
+   Balance assertions
+       hledger supports Ledger-style  balance  assertions  in  journal  files.
+       These  look  like, for example, = EXPECTEDBALANCE following a posting's
+       amount.  Eg here we assert the expected dollar balance  in  accounts  a
+       and b after each posting:
+
+              2013/1/1
+                a   $1  =$1
+                b       =$-1
+
+              2013/1/2
+                a   $1  =$2
+                b  $-1  =$-2
+
+       After reading a journal file, hledger will check all balance assertions
+       and report an error if any of them fail.  Balance assertions  can  pro-
+       tect  you  from, eg, inadvertently disrupting reconciled balances while
+       cleaning up old entries.  You can disable  them  temporarily  with  the
+       -I/--ignore-assertions flag, which can be useful for troubleshooting or
+       for reading Ledger files.  (Note: this flag currently does not  disable
+       balance assignments, below).
+
+   Assertions and ordering
+       hledger  sorts  an  account's postings and assertions first by date and
+       then (for postings on the same day) by parse order.  Note this is  dif-
+       ferent from Ledger, which sorts assertions only by parse order.  (Also,
+       Ledger assertions do not see the accumulated effect of  repeated  post-
+       ings to the same account within a transaction.)
+
+       So, hledger balance assertions keep working if you reorder differently-
+       dated transactions within the journal.  But if you  reorder  same-dated
+       transactions  or postings, assertions might break and require updating.
+       This order dependence does bring an advantage: precise control over the
+       order of postings and assertions within a day, so you can assert intra-
+       day balances.
+
+   Assertions and included files
+       With included files, things are a little more  complicated.   Including
+       preserves  the ordering of postings and assertions.  If you have multi-
+       ple postings to an account on the  same  day,  split  across  different
+       files,  and  you  also want to assert the account's balance on the same
+       day, you'll have to put the assertion in the right file.
+
+   Assertions and multiple -f options
+       Balance assertions don't work well across files specified with multiple
+       -f options.  Use include or concatenate the files instead.
+
+   Assertions and commodities
+       The  asserted  balance must be a simple single-commodity amount, and in
+       fact the assertion checks only  this  commodity's  balance  within  the
+       (possibly  multi-commodity)  account  balance.   This is how assertions
+       work in Ledger also.  We could call this a "partial" balance assertion.
+
+       To assert the balance of more than one commodity in an account, you can
+       write multiple postings, each asserting one commodity's balance.
+
+       You can make a stronger "total" balance assertion by writing  a  double
+       equals sign (== EXPECTEDBALANCE).  This asserts that there are no other
+       unasserted commodities in the account (or, that their balance is 0).
+
+              2013/1/1
+                a   $1
+                a    1EUR
+                b  $-1
+                c   -1EUR
+
+              2013/1/2  ; These assertions succeed
+                a    0  =  $1
+                a    0  =   1EUR
+                b    0 == $-1
+                c    0 ==  -1EUR
+
+              2013/1/3  ; This assertion fails as 'a' also contains 1EUR
+                a    0 ==  $1
+
+       It's not yet possible to make a complete assertion about a balance that
+       has  multiple commodities.  One workaround is to isolate each commodity
+       into its own subaccount:
+
+              2013/1/1
+                a:usd   $1
+                a:euro   1EUR
+                b
+
+              2013/1/2
+                a        0 ==  0
+                a:usd    0 == $1
+                a:euro   0 ==  1EUR
+
+   Assertions and prices
+       Balance assertions ignore transaction prices, and  should  normally  be
+       written without one:
+
+              2019/1/1
+                (a)     $1 @ EUR1 = $1
+
+       We  do allow prices to be written there, however, and print shows them,
+       even though they don't affect whether the assertion  passes  or  fails.
+       This  is  for  backward  compatibility (hledger's close command used to
+       generate balance assertions with prices), and because  balance  assign-
+       ments do use them (see below).
+
+   Assertions and subaccounts
+       The  balance  assertions above (= and ==) do not count the balance from
+       subaccounts; they check the account's exclusive balance only.  You  can
+       assert the balance including subaccounts by writing =* or ==*, eg:
+
+              2019/1/1
+                equity:opening balances
+                checking:a       5
+                checking:b       5
+                checking         1  ==* 11
+
+   Assertions and virtual postings
+       Balance assertions are checked against all postings, both real and vir-
+       tual.  They are not affected by the --real/-R flag or real: query.
+
+   Assertions and precision
+       Balance assertions compare the exactly calculated  amounts,  which  are
+       not  always  what  is  shown  by reports.  Eg a commodity directive may
+       limit the display precision, but this will not  affect  balance  asser-
+       tions.  Balance assertion failure messages show exact amounts.
+
+   Balance assignments
+       Ledger-style  balance  assignments  are also supported.  These are like
+       balance assertions, but with no posting amount on the left side of  the
+       equals  sign;  instead  it is calculated automatically so as to satisfy
+       the assertion.  This can be a convenience during data  entry,  eg  when
+       setting opening balances:
+
+              ; starting a new journal, set asset account balances
+              2016/1/1 opening balances
+                assets:checking            = $409.32
+                assets:savings             = $735.24
+                assets:cash                 = $42
+                equity:opening balances
+
+       or when adjusting a balance to reality:
+
+              ; no cash left; update balance, record any untracked spending as a generic expense
+              2016/1/15
+                assets:cash    = $0
+                expenses:misc
+
+       The calculated amount depends on the account's balance in the commodity
+       at that point (which depends on the previously-dated  postings  of  the
+       commodity  to  that account since the last balance assertion or assign-
+       ment).  Note that using balance assignments makes your journal a little
+       less explicit; to know the exact amount posted, you have to run hledger
+       or do the calculations yourself, instead of just reading it.
+
+   Balance assignments and prices
+       A transaction price in a balance assignment will cause  the  calculated
+       amount to have that price attached:
+
+              2019/1/1
+                (a)             = $1 @ EUR2
+
+              $ hledger print --explicit
+              2019-01-01
+                  (a)         $1 @ EUR2 = $1 @ EUR2
+
+   Directives
+       A  directive is a line in the journal beginning with a special keyword,
+       that influences how the journal is processed.  hledger's directives are
+       based on a subset of Ledger's, but there are many differences (and also
+       some differences between hledger versions).
+
+       Directives' behaviour and interactions can get a little bit complex, so
+       here  is  a  table  summarising  the directives and their effects, with
+       links to more detailed docs.

+       direc-   which entries and (when there are multiple  files)  which  files
+       tive     are affected by a directive
+       scope
+
+       As you can see, directives vary in which journal entries and files they
+       affect, and whether they are focussed  on  input  (parsing)  or  output
+       (reports).  Some directives have multiple effects.
+
+   Directives and multiple files
+       If  you  use  multiple  -f/--file  options,  or  the include directive,
+       hledger will process multiple input files.  But  note  that  directives
+       which affect input (see above) typically last only until the end of the
+       file in which they occur.
+
+       This may seem inconvenient, but it's intentional; it makes reports sta-
+       ble  and  deterministic,  independent of the order of input.  Otherwise
+       you could see different numbers if you happened to write -f options  in
+       a  different  order,  or if you moved includes around while cleaning up
+       your files.
+
+       It can be surprising though; for example, it means  that  alias  direc-
+       tives do not affect parent or sibling files (see below).
+
+   Comment blocks
+       A  line  containing just comment starts a commented region of the file,
+       and a line containing just end comment (or the end of the current file)
+       ends it.  See also comments.
+
+   Including other files
+       You  can  pull in the content of additional files by writing an include
+       directive, like this:
+
+              include FILEPATH
+
+       Only journal files can include, and only journal, timeclock or  timedot
+       files can be included (not CSV files, currently).
+
+       If  the  file  path  does not begin with a slash, it is relative to the
+       current file's folder.
+
+       A tilde means home directory, eg: include ~/main.journal.
+
+       The path may contain glob patterns to match multiple files, eg: include
+       *.journal.
+
+       There  is  limited  support  for recursive wildcards: **/ (the slash is
+       required) matches 0 or more subdirectories.  It's not super  convenient
+       since  you  have to avoid include cycles and including directories, but
+       this can be done, eg: include */**/*.journal.
+
+       The path may also be prefixed to force a specific file format, overrid-
+       ing  the  file  extension  (as  described in hledger.1 -> Input files):
+       include timedot:~/notes/2020*.md.
+
+   Default year
+       You can set a default year to be used for subsequent dates which  don't
+       specify  a year.  This is a line beginning with Y followed by the year.
+       Eg:
+
+              Y2009  ; set default year to 2009
+
+              12/15  ; equivalent to 2009/12/15
+                expenses  1
+                assets
+
+              Y2010  ; change default year to 2010
+
+              2009/1/30  ; specifies the year, not affected
+                expenses  1
+                assets
+
+              1/31   ; equivalent to 2010/1/31
+                expenses  1
+                assets
+
+   Declaring payees
+       The payee directive can be used to declare  a  limited  set  of  payees
+       which  may appear in transaction descriptions.  The "payees" check will
+       report an error if any transaction refers to a payee that has not  been
+       declared.  Eg:
+
+              payee Whole Foods
+
+   Declaring commodities
+       You  can use commodity directives to declare your commodities.  In fact
+       the commodity directive performs several functions at once:
+
+       1. It declares commodities which may be used in the journal.  This  can
+          optionally  be  enforced, providing useful error checking.  (Cf Com-
+          modity error checking)
+
+       2. It declares which decimal  mark  character  (period  or  comma),  to
+          expect  when  parsing  input  - useful to disambiguate international
+          number formats in your data.  Without this, hledger will parse  both
+          1,000 and 1.000 as 1.  (Cf Amounts)
+
+       3. It  declares  how  to render the commodity's amounts when displaying
+          output - the decimal mark, any digit group marks, the number of dec-
+          imal  places,  symbol  placement  and  so on.  (Cf Commodity display
+          style)
+
+       You will run into one of the problems solved  by  commodity  directives
+       sooner or later, so we recommend using them, for robust and predictable
+       parsing and display.
+
+       Generally you should put them at the top of your  journal  file  (since
+       for function 2, they affect only following amounts, cf #793).
+
+       A  commodity  directive is just the word commodity followed by a sample
+       amount, like this:
+
+              ;commodity SAMPLEAMOUNT
+
+              commodity $1000.00
+              commodity 1,000.0000 AAAA  ; optional same-line comment
+
+       It may also be written on multiple lines, and use the format  subdirec-
+       tive,  as  in  Ledger.   Note in this case the commodity symbol appears
+       twice; it must be the same in both places:
+
+              ;commodity SYMBOL
+              ;  format SAMPLEAMOUNT
+
+              ; display indian rupees with currency name on the left,
+              ; thousands, lakhs and crores comma-separated,
+              ; period as decimal point, and two decimal places.
+              commodity INR
+                format INR 1,00,00,000.00
+
+       Remember that if the commodity  symbol  contains  spaces,  numbers,  or
+       punctuation, it must be enclosed in double quotes (cf Commodity).
+
+       The  amount's quantity does not matter; only the format is significant.
+       It must include a decimal mark - either a period or a comma -  followed
+       by 0 or more decimal digits.
+
+       A few more examples:
+
+              # number formats for $, EUR, INR and the no-symbol commodity:
+              commodity $1,000.00
+              commodity EUR 1.000,00
+              commodity INR 9,99,99,999.0
+              commodity 1 000 000.
+
+       Note  hledger  normally  uses  banker's rounding, so 0.5 displayed with
+       zero decimal digits is "0".  (More at Commodity display style.)
+
+   Commodity error checking
+       In strict mode, enabled with the -s/--strict flag, hledger will  report
+       an  error if a commodity symbol is used that has not been declared by a
+       commodity directive.  This works similarly to account  error  checking,
+       see the notes there for more details.
+
+   Default commodity
+       The D directive sets a default commodity, to be used for any subsequent
+       commodityless amounts (ie, plain numbers) seen while parsing the  jour-
+       nal.   This  effect lasts until the next D directive, or the end of the
+       journal.
+
+       For compatibility/historical reasons, D  also  acts  like  a  commodity
+       directive (setting the commodity's decimal mark for parsing and display
+       style for output).
+
+       As with commodity, the amount  must  include  a  decimal  mark  (either
+       period  or comma).  If both commodity and D directives are used for the
+       same commodity, the commodity style takes precedence.
+
+       The syntax is D AMOUNT.  Eg:
+
+              ; commodity-less amounts should be treated as dollars
+              ; (and displayed with the dollar sign on the left, thousands separators and two decimal places)
+              D $1,000.00
+
+              1/1
+                a     5  ; <- commodity-less amount, parsed as $5 and displayed as $5.00
+                b
+
+   Declaring market prices
+       The P directive declares a market price,  which  is  an  exchange  rate
+       between two commodities on a certain date.  (In Ledger, they are called
+       "historical prices".) These are often obtained from a  stock  exchange,
+       cryptocurrency exchange, or the foreign exchange market.
+
+       The format is:
+
+              P DATE COMMODITY1SYMBOL COMMODITY2AMOUNT
+
+       DATE  is a simple date, COMMODITY1SYMBOL is the symbol of the commodity
+       being priced, and COMMODITY2AMOUNT is the amount (symbol and  quantity)
+       of  commodity  2  that  one  unit of commodity 1 is worth on this date.
+       Examples:
+
+              # one euro was worth $1.35 from 2009-01-01 onward:
+              P 2009-01-01 EUR $1.35
+
+              # and $1.40 from 2010-01-01 onward:
+              P 2010-01-01 EUR $1.40
+
+       The -V, -X and --value flags use these market  prices  to  show  amount
+       values in another commodity.  See Valuation.
+
+   Declaring accounts
+       account directives can be used to declare accounts (ie, the places that
+       amounts are transferred from and to).  Though not required, these  dec-
+       larations can provide several benefits:
+
+       o They can document your intended chart of accounts, providing a refer-
+         ence.
+
+       o They can help hledger know your accounts'  types  (asset,  liability,
+         equity,  revenue,  expense), useful for reports like balancesheet and
+         incomestatement.
+
+       o They control account display order in  reports,  allowing  non-alpha-
+         betic sorting (eg Revenues to appear above Expenses).
+
+       o They  can  store  extra  information about accounts (account numbers,
+         notes, etc.)
+
+       o They help with account name completion in the add  command,  hledger-
+         iadd, hledger-web, ledger-mode etc.
+
+       o In  strict  mode,  they  restrict  which accounts may be posted to by
+         transactions, which helps detect typos.
+
+       The simplest form is just the word account followed by a  hledger-style
+       account name, eg this account directive declares the assets:bank:check-
+       ing account:
+
+              account assets:bank:checking
+
+   Account error checking
+       By default, accounts come into existence when a transaction  references
+       them  by name.  This is convenient, but it means hledger can't warn you
+       when you mis-spell an account name in the journal.  Usually you'll find
+       the  error  later, as an extra account in balance reports, or an incor-
+       rect balance when reconciling.
+
+       In strict mode, enabled with the -s/--strict flag, hledger will  report
+       an  error  if  any  transaction  uses an account name that has not been
+       declared by an account directive.  Some notes:
+
+       o The declaration is case-sensitive; transactions must use the  correct
+         account name capitalisation.
+
+       o The  account  directive's scope is "whole file and below" (see direc-
+         tives).  This means it affects all of the current file, and any files
+         it  includes,  but  not  parent  or  sibling  files.  The position of
+         account directives within the file does not matter, though it's usual
+         to put them at the top.
+
+       o Accounts  can  only  be  declared  in  journal files (but will affect
+         included files in other formats).
+
+       o It's currently not possible to  declare  "all  possible  subaccounts"
+         with a wildcard; every account posted to must be declared.
+
+   Account comments
+       Comments, beginning with a semicolon, can be added:
+
+       o on  the  same line, after two or more spaces (because ; is allowed in
+         account names)
+
+       o on the next lines, indented
+
+       An example of both:
+
+              account assets:bank:checking  ; same-line comment, note 2+ spaces before ;
+                ; next-line comment
+                ; another with tag, acctno:12345 (not used yet)
+
+       Same-line comments are not supported by Ledger, or hledger <1.13.
+
+   Account subdirectives
+       We also allow (and ignore) Ledger-style  indented  subdirectives,  just
+       for compatibility.:
+
+              account assets:bank:checking
+                format blah blah  ; <- subdirective, ignored
+
+       Here is the full syntax of account directives:
+
+              account ACCTNAME  [ACCTTYPE] [;COMMENT]
+                [;COMMENTS]
+                [LEDGER-STYLE SUBDIRECTIVES, IGNORED]
+
+   Account types
+       hledger  recognises  five  main  types of account, corresponding to the
+       account classes in the accounting equation:
+
+       Asset, Liability, Equity, Revenue, Expense.
+
+       These account types are important for controlling which accounts appear
+       in  the  balancesheet, balancesheetequity, incomestatement reports (and
+       probably for other things in future).
+
+       Additionally, we recognise the Cash type, which is also an  Asset,  and
+       which  causes  accounts to appear in the cashflow report.  ("Cash" here
+       means liquid assets, eg bank balances but typically not investments  or
+       receivables.)
+
+   Declaring account types
+       Generally, to make these reports work you should declare your top-level
+       accounts and their types, using account directives with type: tags.
+
+       The tag's value should be one of: Asset,  Liability,  Equity,  Revenue,
+       Expense,  Cash,  A,  L, E, R, X, C (all case insensitive).  The type is
+       inherited by all subaccounts except where they override it.   Here's  a
+       complete example:
+
+              account assets       ; type: Asset
+              account assets:bank  ; type: Cash
+              account assets:cash  ; type: Cash
+              account liabilities  ; type: Liability
+              account equity       ; type: Equity
+              account revenues     ; type: Revenue
+              account expenses     ; type: Expense
+
+   Auto-detected account types
+       If  you  happen  to use common english top-level account names, you may
+       not need to declare account types, as they will be  detected  automati-
+       cally using the following rules:
+
+               If account's name matches this regular expression:                 | its type is:
+              ------------------------------------------------------------------- | ------------
+               ^assets?(:|$)                                                      |
+                 and does not contain regexp (investment|receivable|:A/R|:fixed)  | Cash
+                 otherwise                                                        | Asset
+               ^(debts?|liabilit(y|ies))(:|$)                                     | Liability
+               ^equity(:|$)                                                       | Equity
+               ^(income|revenue)s?(:|$)                                           | Revenue
+               ^expenses?(:|$)                                                    | Expense
+
+       Even so, explicit declarations may be a good idea, for clarity and pre-
+       dictability.
+
+   Interference from auto-detected account types
+       If you assign any account type, it's a good idea to assign all of them,
+       to  prevent any confusion from mixing declared and auto-detected types.
+       Although it's unlikely to happen in real life, here's an example:  with
+       the  following  journal, balancesheetequity shows "liabilities" in both
+       Liabilities  and  Equity  sections.   Declaring  another   account   as
+       type:Liability would fix it:
+
+              account liabilities  ; type:Equity
+
+              2020-01-01
+                assets        1
+                liabilities   1
+                equity       -2
+
+   Old account type syntax
+       In  some  hledger  journals  you might instead see this old syntax (the
+       letters ALERX, separated from the account name by two or more  spaces);
+       this is deprecated and may be removed soon:
+
+              account assets       A
+              account liabilities  L
+              account equity       E
+              account revenues     R
+              account expenses     X
+
+   Account display order
+       Account  directives also set the order in which accounts are displayed,
+       eg in reports, the hledger-ui  accounts  screen,  and  the  hledger-web
+       sidebar.  By default accounts are listed in alphabetical order.  But if
+       you have these account directives in the journal:
+
+              account assets
+              account liabilities
+              account equity
+              account revenues
+              account expenses
+
+       you'll see those accounts displayed in declaration order, not alphabet-
+       ically:
+
+              $ hledger accounts -1
+              assets
+              liabilities
+              equity
+              revenues
+              expenses
+
+       Undeclared accounts, if any, are displayed last, in alphabetical order.
+
+       Note that sorting is done at each level of  the  account  tree  (within
+       each  group of sibling accounts under the same parent).  And currently,
+       this directive:
+
+              account other:zoo
+
+       would influence the position of zoo among other's subaccounts, but  not
+       the position of other among the top-level accounts.  This means:
+
+       o you  will  sometimes declare parent accounts (eg account other above)
+         that you don't intend to post to, just  to  customize  their  display
+         order
+
+       o sibling  accounts  stay together (you couldn't display x:y in between
+         a:b and a:c).
+
+   Rewriting accounts
+       You can define account alias rules which rewrite your account names, or
+       parts of them, before generating reports.  This can be useful for:
+
+       o expanding shorthand account names to their full form, allowing easier
+         data entry and a less verbose journal
+
+       o adapting old journals to your current chart of accounts
+
+       o experimenting with new account organisations, like a new hierarchy or
+         combining two accounts into one
+
+       o customising reports
+
+       Account aliases also rewrite account names in account directives.  They
+       do not affect account names being entered via hledger add  or  hledger-
+       web.
+
+       See also Rewrite account names.
+
+   Basic aliases
+       To  set an account alias, use the alias directive in your journal file.
+       This affects all subsequent journal entries in the current file or  its
+       included  files  (but  note:  not sibling or parent files).  The spaces
+       around the = are optional:
+
+              alias OLD = NEW
+
+       Or, you can use the --alias 'OLD=NEW' option on the command line.  This
+       affects all entries.  It's useful for trying out aliases interactively.
+
+       OLD and NEW are  case  sensitive  full  account  names.   hledger  will
+       replace  any occurrence of the old account name with the new one.  Sub-
+       accounts are also affected.  Eg:
+
+              alias checking = assets:bank:wells fargo:checking
+              ; rewrites "checking" to "assets:bank:wells fargo:checking", or "checking:a" to "assets:bank:wells fargo:checking:a"
+
+   Regex aliases
+       There is also a more powerful variant that uses a  regular  expression,
+       indicated by the forward slashes:
+
+              alias /REGEX/ = REPLACEMENT
+
+       or --alias '/REGEX/=REPLACEMENT'.
+
+       REGEX  is  a  case-insensitive regular expression.  Anywhere it matches
+       inside an account name, the matched part will be replaced  by  REPLACE-
+       MENT.   If REGEX contains parenthesised match groups, these can be ref-
+       erenced by the usual numeric backreferences in REPLACEMENT.  Eg:
+
+              alias /^(.+):bank:([^:]+):(.*)/ = \1:\2 \3
+              ; rewrites "assets:bank:wells fargo:checking" to  "assets:wells fargo checking"
+
+       Also note that REPLACEMENT continues to the end of line (or on  command
+       line,  to  end  of  option argument), so it can contain trailing white-
+       space.
+
+   Combining aliases
+       You can define as many aliases as you like,  using  journal  directives
+       and/or command line options.
+
+       Recursive  aliases  -  where an account name is rewritten by one alias,
+       then by another alias, and so on - are allowed.  Each  alias  sees  the
+       effect of previously applied aliases.
+
+       In  such  cases it can be important to understand which aliases will be
+       applied and in which order.  For (each account name  in)  each  journal
+       entry, we apply:
+
+       1. alias  directives  preceding the journal entry, most recently parsed
+          first (ie, reading upward from the journal entry, bottom to top)
+
+       2. --alias options, in the order they  appeared  on  the  command  line
+          (left to right).
+
+       In other words, for (an account name in) a given journal entry:
+
+       o the nearest alias declaration before/above the entry is applied first
+
+       o the next alias before/above that will be be applied next, and so on
+
+       o aliases defined after/below the entry do not affect it.
+
+       This gives nearby aliases precedence over distant ones, and helps  pro-
+       vide  semantic stability - aliases will keep working the same way inde-
+       pendent of which files are being read and in which order.
+
+       In case of trouble, adding --debug=6 to  the  command  line  will  show
+       which aliases are being applied when.
+
+   Aliases and multiple files
+       As  explained at Directives and multiple files, alias directives do not
+       affect parent or sibling files.  Eg in this command,
+
+              hledger -f a.aliases -f b.journal
+
+       account  aliases  defined  in  a.aliases  will  not  affect  b.journal.
+       Including the aliases doesn't work either:
+
+              include a.aliases
+
+              2020-01-01  ; not affected by a.aliases
+                foo  1
+                bar
+
+       This means that account aliases should usually be declared at the start
+       of your top-most file, like this:
+
+              alias foo=Foo
+              alias bar=Bar
+
+              2020-01-01  ; affected by aliases above
+                foo  1
+                bar
+
+              include c.journal  ; also affected
+
+   end aliases
+       You can clear (forget) all  currently  defined  aliases  with  the  end
+       aliases directive:
+
+              end aliases
+
+   Default parent account
+       You  can  specify  a  parent  account  which  will  be prepended to all
+       accounts within a section of the journal.  Use the  apply  account  and
+       end apply account directives like so:
+
+              apply account home
+
+              2010/1/1
+                  food    $10
+                  cash
+
+              end apply account
+
+       which is equivalent to:
+
+              2010/01/01
+                  home:food           $10
+                  home:cash          $-10
+
+       If  end  apply  account  is omitted, the effect lasts to the end of the
+       file.  Included files are also affected, eg:
+
+              apply account business
+              include biz.journal
+              end apply account
+              apply account personal
+              include personal.journal
+
+       Prior to hledger 1.0, legacy account and end spellings were  also  sup-
+       ported.
+
+       A  default parent account also affects account directives.  It does not
+       affect account names being entered via hledger add or hledger-web.   If
+       account  aliases are present, they are applied after the default parent
+       account.
+
+   Periodic transactions
+       Periodic transaction rules  describe  transactions  that  recur.   They
+       allow  hledger  to  generate temporary future transactions to help with
+       forecasting, so you don't have to write out each one  in  the  journal,
+       and it's easy to try out different forecasts.
+
+       Periodic  transactions  can be a little tricky, so before you use them,
+       read this whole section - or at least these tips:
+
+       1. Two spaces accidentally added or omitted will cause  you  trouble  -
+          read about this below.
+
+       2. For  troubleshooting,  show  the generated transactions with hledger
+          print  --forecast  tag:generated  or  hledger  register   --forecast
+          tag:generated.
+
+       3. Forecasted  transactions  will  begin  only after the last non-fore-
+          casted transaction's date.
+
+       4. Forecasted transactions will end 6 months from  today,  by  default.
+          See below for the exact start/end rules.
+
+       5. period   expressions  can  be  tricky.   Their  documentation  needs
+          improvement, but is worth studying.
+
+       6. Some period expressions with a repeating interval must  begin  on  a
+          natural  boundary  of  that  interval.  Eg in weekly from DATE, DATE
+          must be a monday.  ~ weekly from 2019/10/1 (a tuesday) will give  an
+          error.
+
+       7. Other period expressions with an interval are automatically expanded
+          to cover a whole number of that interval.  (This is done to  improve
+          reports, but it also affects periodic transactions.  Yes, it's a bit
+          inconsistent with the above.) Eg: ~ every 10th  day  of  month  from
+          2020/01,  which  is  equivalent  to  ~  every 10th day of month from
+          2020/01/01, will be adjusted to start on 2019/12/10.
+
+       Periodic transaction rules also have a second meaning: they are used to
+       define budget goals, shown in budget reports.
+
+   Periodic rule syntax
+       A periodic transaction rule looks like a normal journal entry, with the
+       date replaced by a tilde (~) followed by a period expression (mnemonic:
+       ~ looks like a recurring sine wave.):
+
+              ~ monthly
+                  expenses:rent          $2000
+                  assets:bank:checking
+
+       There  is  an additional constraint on the period expression: the start
+       date must fall on a natural boundary of the interval.  Eg monthly  from
+       2018/1/1 is valid, but monthly from 2018/1/15 is not.
+
+       Partial  or  relative dates (M/D, D, tomorrow, last week) in the period
+       expression can work (useful or not).  They will be relative to  today's
+       date,  unless  a  Y  default year directive is in effect, in which case
+       they will be relative to Y/1/1.
+
+   Two spaces between period expression and description!
+       If the period expression is  followed  by  a  transaction  description,
+       these must be separated by two or more spaces.  This helps hledger know
+       where the period expression ends, so that descriptions can not acciden-
+       tally alter their meaning, as in this example:
+
+              ; 2 or more spaces needed here, so the period is not understood as "every 2 months in 2020"
+              ;               ||
+              ;               vv
+              ~ every 2 months  in 2020, we will review
+                  assets:bank:checking   $1500
+                  income:acme inc
+
+       So,
+
+       o Do  write two spaces between your period expression and your transac-
+         tion description, if any.
+
+       o Don't accidentally write two spaces in  the  middle  of  your  period
+         expression.
+
+   Forecasting with periodic transactions
+       The  --forecast  flag  activates  any periodic transaction rules in the
+       journal.  They will generate temporary  recurring  transactions,  which
+       are  not  saved  in  the  journal,  but  will appear in all reports (eg
+       print).  This can be useful for estimating balances into the future, or
+       experimenting  with  different scenarios.  Or, it can be used as a data
+       entry aid: describe recurring transactions, and every so often copy the
+       output of print --forecast into the journal.
+
+       These  transactions  will  have  an extra tag indicating which periodic
+       rule generated them: generated-transaction:~ PERIODICEXPR.  And a simi-
+       lar,  hidden  tag  (beginning  with  an underscore) which, because it's
+       never displayed by print, can be used to match  transactions  generated
+       "just now": _generated-transaction:~ PERIODICEXPR.
+
+       Periodic  transactions  are  generated within some forecast period.  By
+       default, this
+
+       o begins on the later of
+
+         o the report start date if specified with -b/-p/date:
+
+         o the day after the latest normal (non-periodic) transaction  in  the
+           journal, or today if there are no normal transactions.
+
+       o ends  on  the  report  end  date  if specified with -e/-p/date:, or 6
+         months (180 days) from today.
+
+       This means that periodic transactions will begin only after the  latest
+       recorded  transaction.   And a recorded transaction dated in the future
+       can prevent generation of periodic transactions.  (You can  avoid  that
+       by writing the future transaction as a one-time periodic rule instead -
+       put tilde before the date, eg ~ YYYY-MM-DD ...).
+
+       Or, you can set your own arbitrary "forecast period", which can overlap
+       recorded  transactions,  and need not be in the future, by providing an
+       option argument, like --forecast=PERIODEXPR.  Note the equals  sign  is
+       required, a space won't work.  PERIODEXPR is a period expression, which
+       can specify the start date, end date, or both, like in a  date:  query.
+       (See  also  hledger.1  ->  Report  start  &  end date).  Some examples:
+       --forecast=202001-202004, --forecast=jan-, --forecast=2020.
+
+   Budgeting with periodic transactions
+       With the --budget flag, currently supported  by  the  balance  command,
+       each  periodic transaction rule declares recurring budget goals for the
+       specified accounts.  Eg the first example  above  declares  a  goal  of
+       spending  $2000  on  rent  (and  also,  a goal of depositing $2000 into
+       checking) every month.  Goals and actual performance can then  be  com-
+       pared in budget reports.
+
+       See also: Budgeting and Forecasting.
+
+
+   Auto postings
+       "Automated  postings"  or  "auto postings" are extra postings which get
+       added  automatically  to  transactions  which  match  certain  queries,
+       defined by "auto posting rules", when you use the --auto flag.
+
+       An auto posting rule looks a bit like a transaction:
+
+              = QUERY
+                  ACCOUNT  AMOUNT
+                  ...
+                  ACCOUNT  [AMOUNT]
+
+       except  the  first  line is an equals sign (mnemonic: = suggests match-
+       ing), followed by a query (which matches existing postings),  and  each
+       "posting"  line  describes  a  posting to be generated, and the posting
+       amounts can be:
+
+       o a normal amount with a commodity symbol, eg $2.  This  will  be  used
+         as-is.
+
+       o a number, eg 2.  The commodity symbol (if any) from the matched post-
+         ing will be added to this.
+
+       o a numeric multiplier, eg *2 (a star followed by  a  number  N).   The
+         matched posting's amount (and total price, if any) will be multiplied
+         by N.
+
+       o a multiplier with a commodity symbol, eg *$2 (a star, number  N,  and
+         symbol S).  The matched posting's amount will be multiplied by N, and
+         its commodity symbol will be replaced with S.
+
+       Any query term containing spaces must be enclosed in single  or  double
+       quotes,  as on the command line.  Eg, note the quotes around the second
+       query term below:
+
+              = expenses:groceries 'expenses:dining out'
+                  (budget:funds:dining out)                 *-1
+
+       Some examples:
+
+              ; every time I buy food, schedule a dollar donation
+              = expenses:food
+                  (liabilities:charity)   $-1
+
+              ; when I buy a gift, also deduct that amount from a budget envelope subaccount
+              = expenses:gifts
+                  assets:checking:gifts  *-1
+                  assets:checking         *1
+
+              2017/12/1
+                expenses:food    $10
+                assets:checking
+
+              2017/12/14
+                expenses:gifts   $20
+                assets:checking
+
+              $ hledger print --auto
+              2017-12-01
+                  expenses:food              $10
+                  assets:checking
+                  (liabilities:charity)      $-1
+
+              2017-12-14
+                  expenses:gifts             $20
+                  assets:checking
+                  assets:checking:gifts     -$20
+                  assets:checking            $20
+
+   Auto postings and multiple files
+       An auto posting rule can affect any transaction in the current file, or
+       in  any  parent file or child file.  Note, currently it will not affect
+       sibling files (when multiple -f/--file are used - see #1212).
+
+   Auto postings and dates
+       A posting date (or secondary date) in the matched posting,  or  (taking
+       precedence)  a  posting date in the auto posting rule itself, will also
+       be used in the generated posting.
+
+   Auto postings and transaction balancing / inferred amounts / balance asser-
+       tions
+       Currently, auto postings are added:
+
+       o after  missing amounts are inferred, and transactions are checked for
+         balancedness,
+
+       o but before balance assertions are checked.
+
+       Note this means that journal entries must be balanced both  before  and
+       after auto postings are added.  This changed in hledger 1.12+; see #893
+       for background.
+
+   Auto posting tags
+       Automated postings will have some extra tags:
+
+       o generated-posting:= QUERY - shows this was generated by an auto post-
+         ing rule, and the query
+
+       o _generated-posting:=  QUERY  - a hidden tag, which does not appear in
+         hledger's output.  This can be used to match postings generated "just
+         now", rather than generated in the past and saved to the journal.
+
+       Also,  any transaction that has been changed by auto posting rules will
+       have these tags added:
+
+       o modified: - this transaction was modified
+
+       o _modified: - a hidden tag not appearing in the comment; this transac-
+         tion was modified "just now".
+
+CSV FORMAT
+       How hledger reads CSV data, and the CSV rules file format.
+
+       hledger  can read CSV files (Character Separated Value - usually comma,
+       semicolon, or tab) containing dated records as  if  they  were  journal
+       files, automatically converting each CSV record into a transaction.
+
+       (To learn about writing CSV, see CSV output.)
+
+       We describe each CSV file's format with a corresponding rules file.  By
+       default this is named like the CSV file with a .rules extension  added.
+       Eg  when reading FILE.csv, hledger also looks for FILE.csv.rules in the
+       same directory as FILE.csv.  You can specify  a  different  rules  file
+       with  the  --rules-file  option.  If a rules file is not found, hledger
+       will create a sample rules file, which you'll need to adjust.
+
+       This file contains rules describing the CSV data (header  line,  fields
+       layout, date format etc.), and how to construct hledger journal entries
+       (transactions) from it.  Often there will also be a list of conditional
+       rules  for  categorising  transactions  based  on  their  descriptions.
+       Here's an overview of the CSV rules; these  are  described  more  fully
+       below, after the examples:
+
+

+       There's an introductory Convert CSV files tutorial on hledger.org.
+
+   Examples
+       Here  are  some sample hledger CSV rules files.  See also the full col-
+       lection at:
+       https://github.com/simonmichael/hledger/tree/master/examples/csv
+
+   Basic
+       At minimum, the rules file must identify the date  and  amount  fields,
+       and  often  it also specifies the date format and how many header lines
+       there are.  Here's a simple CSV file and a rules file for it:
+
+              Date, Description, Id, Amount
+              12/11/2019, Foo, 123, 10.23
+
+              # basic.csv.rules
+              skip         1
+              fields       date, description, _, amount
+              date-format  %d/%m/%Y
+
+              $ hledger print -f basic.csv
+              2019-11-12 Foo
+                  expenses:unknown           10.23
+                  income:unknown            -10.23
+
+       Default account names are chosen, since we didn't set them.
+
+   Bank of Ireland
+       Here's a CSV with two amount fields (Debit and Credit), and  a  balance
+       field,  which we can use to add balance assertions, which is not neces-
+       sary but provides extra error checking:
+
+              Date,Details,Debit,Credit,Balance
+              07/12/2012,LODGMENT       529898,,10.0,131.21
+              07/12/2012,PAYMENT,5,,126
+
+              # bankofireland-checking.csv.rules
+
+              # skip the header line
+              skip
+
+              # name the csv fields, and assign some of them as journal entry fields
+              fields  date, description, amount-out, amount-in, balance
+
+              # We generate balance assertions by assigning to "balance"
+              # above, but you may sometimes need to remove these because:
+              #
+              # - the CSV balance differs from the true balance,
+              #   by up to 0.0000000000005 in my experience
+              #
+              # - it is sometimes calculated based on non-chronological ordering,
+              #   eg when multiple transactions clear on the same day
+
+              # date is in UK/Ireland format
+              date-format  %d/%m/%Y
+

+              currency  EUR

+              # set the base account for all txns
+              account1  assets:bank:boi:checking
+
+              $ hledger -f bankofireland-checking.csv print

+                  expenses:unknown                  EUR5.0
+
+       The balance assertions don't raise an error above, because we're  read-
+       ing  directly  from  CSV, but they will be checked if these entries are
+       imported into a journal file.

+
+   CSV rules
+       The following kinds of rule can appear in the rules file, in any order.
+       Blank lines and lines beginning with # or ; are ignored.
+
+   skip
+              skip N
+
+       The word "skip" followed by a number (or no number,  meaning  1)  tells
+       hledger  to  ignore  this  many non-empty lines preceding the CSV data.
+       (Empty/blank lines are skipped automatically.) You'll need  this  when-
+       ever your CSV data contains header lines.
+
+       It also has a second purpose: it can be used inside if blocks to ignore
+       certain CSV records (described below).
+
+   fields list
+              fields FIELDNAME1, FIELDNAME2, ...
+
+       A fields list (the word  "fields"  followed  by  comma-separated  field
+       names)  is  the quick way to assign CSV field values to hledger fields.
+       (The other way is field assignments, see below.)  A  fields  list  does
+       does two things:
+
+       1. It  names  the  CSV fields.  This is optional, but can be convenient
+          later for interpolating them.
+
+       2. Whenever you use a standard hledger field name (defined below),  the
+          CSV value is assigned to that part of the hledger transaction.
+
+       Here's  an  example  that  says "use the 1st, 2nd and 4th fields as the
+       transaction's date, description and amount; name the  last  two  fields
+       for later reference; and ignore the others":
+
+              fields date, description, , amount, , , somefield, anotherfield
+
+       Tips:
+
+       o The fields list always use commas, even if your CSV data uses another
+         separator character.
+
+       o Currently there must be least two items in the  list  (at  least  one
+         comma).
+
+       o Field  names may not contain spaces.  Spaces before/after field names
+         are optional.
+
+       o If the CSV contains column headings, it's a good idea to  use  these,
+         suitably modified, as the basis for your field names (eg lower-cased,
+         with underscores instead of spaces).
+
+       o If some heading names match standard hledger fields,  but  you  don't
+         want  to  set  the  hledger fields directly, alter those names, eg by
+         appending an underscore.
+
+       o Fields you don't care about can be given a dummy name (eg: _ ), or no
+         name.
+
+   field assignment
+              HLEDGERFIELDNAME FIELDVALUE
+
+       Field  assignments  are  the  more flexible way to assign CSV values to
+       hledger fields.  They can be used instead of or in addition to a fields
+       list (see above).
+
+       To  assign a value to a hledger field, write the field name (any of the
+       standard hledger field/pseudo-field names,  defined  below),  a  space,
+       followed  by a text value on the same line.  This text value may inter-
+       polate CSV fields, referenced by their  1-based  position  in  the  CSV
+       record  (%N),  or by the name they were given in the fields list (%CSV-
+       FIELDNAME).
+
+       Some examples:
+
+              # set the amount to the 4th CSV field, with " USD" appended
+              amount %4 USD
+
+              # combine three fields to make a comment, containing note: and date: tags
+              comment note: %somefield - %anotherfield, date: %1
+
+       Tips:
+
+       o Interpolation strips outer whitespace (so a CSV  value  like  "  1  "
+         becomes 1 when interpolated) (#1051).
+
+       o See also Tips below.
+
+   Field names
+       Here are the standard hledger field (and pseudo-field) names, which you
+       can use in a fields list and in field assignments.  For more about  the
+       transaction parts they refer to, see Transactions.
+
+   date field
+       Assigning to date sets the transaction date.
+
+   date2 field
+       date2 sets the transaction's secondary date, if any.
+
+   status field
+       status sets the transaction's status, if any.
+
+   code field
+       code sets the transaction's code, if any.
+
+   description field
+       description sets the transaction's description, if any.
+
+   comment field
+       comment sets the transaction's comment, if any.
+
+       commentN, where N is a number, sets the Nth posting's comment.
+
+       Tips: - Only single-line comments can be assigned.  - Comments can con-
+       tain tags, as usual.
+
+   account field
+       Assigning to accountN, where N is 1 to 99, sets the account name of the
+       Nth posting, and causes that posting to be generated.
+
+       Most  often  there are two postings, so you'll want to set account1 and
+       account2.  Typically account1 is associated with the CSV file,  and  is
+       set  once  with  a top-level assignment, while account2 is set based on
+       each transaction's description, and in conditional blocks.
+
+       If a posting's account name is left unset but its amount  is  set  (see
+       below),  a default account name will be chosen (like "expenses:unknown"
+       or "income:unknown").
+
+   amount field
+       amountN sets the amount of the Nth posting, and causes that posting  to
+       be  generated.   By  assigning  to amount1, amount2, ...  etc.  you can
+       generate up to 99 postings.
+
+       amountN-in and amountN-out can be used instead, if the CSV  uses  sepa-
+       rate  fields  for  debits  and credits (inflows and outflows).  hledger
+       assumes both of these CSV fields are unsigned, and  will  automatically
+       negate  the  "-out"  value.   If they are signed, see "Setting amounts"
+       below.
+
+       amount, or amount-in and amount-out are a legacy  mode,  to  keep  pre-
+       hledger-1.17  CSV rules files working (and for occasional convenience).
+       They are suitable only for  two-posting  transactions;  they  set  both
+       posting  1's  and  posting  2's  amount.   Posting  2's  amount will be
+       negated, and also converted to cost if there's a transaction price.
+
+       If you have an existing rules file using the unnumbered form, you might
+       want  to  use  the numbered form in certain conditional blocks, without
+       having to update and retest all the old  rules.   To  facilitate  this,
+       posting    1    ignores    amount/amount-in/amount-out    if   any   of
+       amount1/amount1-in/amount1-out are assigned, and posting 2 ignores them
+       if  any  of  amount2/amount2-in/amount2-out are assigned, avoiding con-
+       flicts.
+
+   currency field
+       currency sets a currency symbol,  to  be  prepended  to  all  postings'
+       amounts.   You  can  use this if the CSV amounts do not have a currency
+       symbol, eg if it is in a separate column.
+
+       currencyN prepends a currency symbol to just the Nth posting's  amount.
+
+   balance field
+       balanceN  sets  a balance assertion amount (or if the posting amount is
+       left empty, a balance assignment) on posting N.
+
+       balance is a compatibility spelling for hledger <1.17; it is equivalent
+       to balance1.
+
+       You  can  adjust the type of assertion/assignment with the balance-type
+       rule (see below).
+
+       See Tips below for more about setting amounts and currency.
+
+   separator
+       You can use the separator rule to read other kinds  of  character-sepa-
+       rated  data.   The  argument  is any single separator character, or the
+       words tab or space (case insensitive).  Eg, for comma-separated  values
+       (CSV):
+
+              separator ,
+
+       or for semicolon-separated values (SSV):
+
+              separator ;
+
+       or for tab-separated values (TSV):
+
+              separator TAB
+
+       If  the  input file has a .csv, .ssv or .tsv file extension (or a csv:,
+       ssv:, tsv: prefix), the appropriate separator will be inferred automat-
+       ically, and you won't need this rule.
+
+   if block
+              if MATCHER
+               RULE
+
+              if
+              MATCHER
+              MATCHER
+              MATCHER
+               RULE
+               RULE
+
+       Conditional  blocks ("if blocks") are a block of rules that are applied
+       only to CSV records which match certain patterns.  They are often  used
+       for customising account names based on transaction descriptions.
+
+   Matching the whole record
+       Each MATCHER can be a record matcher, which looks like this:
+
+              REGEX
+
+       REGEX is a case-insensitive regular expression that tries to match any-
+       where within the CSV record.  It  is  a  POSIX  ERE  (extended  regular
+       expression)  that  also  supports GNU word boundaries (\b, \B, \<, \>),
+       and nothing else.  If you have trouble,  be  sure  to  check  our  doc:
+       https://hledger.org/hledger.html#regular-expressions
+
+       Important  note: the record that is matched is not the original record,
+       but a synthetic one, with any enclosing double quotes (but not  enclos-
+       ing whitespace) removed, and always comma-separated (which means that a
+       field containing a comma will appear like  two  fields).   Eg,  if  the
+       original  record  is  2020-01-01;  "Acme, Inc.";  1,000, the REGEX will
+       actually see 2020-01-01,Acme, Inc.,  1,000).
+
+   Matching individual fields
+       Or, MATCHER can be a field matcher, like this:
+
+              %CSVFIELD REGEX
+
+       which matches just the content of a particular CSV field.  CSVFIELD  is
+       a  percent  sign  followed  by  the field's name or column number, like
+       %date or %1.
+
+   Combining matchers
+       A single matcher can be written on the same line as the "if"; or multi-
+       ple matchers can be written on the following lines, non-indented.  Mul-
+       tiple matchers are OR'd (any one of them can match), unless one  begins
+       with an & symbol, in which case it is AND'ed with the previous matcher.
+
+              if
+              MATCHER
+              & MATCHER
+               RULE
+
+   Rules applied on successful match
+       After the patterns there should be one or  more  rules  to  apply,  all
+       indented  by  at  least  one space.  Three kinds of rule are allowed in
+       conditional blocks:
+
+       o field assignments (to set a hledger field)
+
+       o skip (to skip the matched CSV record)
+
+       o end (to skip all remaining CSV records).
+
+       Examples:
+
+              # if the CSV record contains "groceries", set account2 to "expenses:groceries"
+              if groceries
+               account2 expenses:groceries
+
+              # if the CSV record contains any of these patterns, set account2 and comment as shown
+              if
+              monthly service fee
+              atm transaction fee
+              banking thru software
+               account2 expenses:business:banking
+               comment  XXX deductible ? check it
+
+   if table
+              if,CSVFIELDNAME1,CSVFIELDNAME2,...,CSVFIELDNAMEn
+              MATCHER1,VALUE11,VALUE12,...,VALUE1n
+              MATCHER2,VALUE21,VALUE22,...,VALUE2n
+              MATCHER3,VALUE31,VALUE32,...,VALUE3n
+              <empty line>
+
+       Conditional tables ("if tables") are  a  different  syntax  to  specify
+       field  assignments that will be applied only to CSV records which match
+       certain patterns.
+
+       MATCHER could be either field or record matcher,  as  described  above.
+       When MATCHER matches, values from that row would be assigned to the CSV
+       fields named on the if line, in the same order.
+
+       Therefore if table is exactly equivalent to a sequence of of if blocks:
+
+              if MATCHER1
+                CSVFIELDNAME1 VALUE11
+                CSVFIELDNAME2 VALUE12
+                ...
+                CSVFIELDNAMEn VALUE1n
+
+              if MATCHER2
+                CSVFIELDNAME1 VALUE21
+                CSVFIELDNAME2 VALUE22
+                ...
+                CSVFIELDNAMEn VALUE2n
+
+              if MATCHER3
+                CSVFIELDNAME1 VALUE31
+                CSVFIELDNAME2 VALUE32
+                ...
+                CSVFIELDNAMEn VALUE3n
+
+       Each  line starting with MATCHER should contain enough (possibly empty)
+       values for all the listed fields.
+
+       Rules would be checked and applied in the order they are listed in  the
+       table and, like with if blocks, later rules (in the same or another ta-
+       ble) or if blocks could override the effect of any rule.
+
+       Instead of ',' you can use a variety of other non-alphanumeric  charac-
+       ters as a separator.  First character after if is taken to be the sepa-
+       rator for the rest of the table.  It is the responsibility of the  user
+       to  ensure  that  separator does not occur inside MATCHERs and values -
+       there is no way to escape separator.
+
+       Example:
+
+              if,account2,comment
+              atm transaction fee,expenses:business:banking,deductible? check it
+              %description groceries,expenses:groceries,
+              2020/01/12.*Plumbing LLC,expenses:house:upkeep,emergency plumbing call-out
+
+   end
+       This rule can be used inside if blocks (only),  to  make  hledger  stop
+       reading this CSV file and move on to the next input file, or to command
+       execution.  Eg:
+
+              # ignore everything following the first empty record
+              if ,,,,
+               end
+
+   date-format
+              date-format DATEFMT
+
+       This is a helper for the date (and date2) fields.  If  your  CSV  dates
+       are  not  formatted  like  YYYY-MM-DD, YYYY/MM/DD or YYYY.MM.DD, you'll
+       need to add a date-format rule describing them  with  a  strptime  date
+       parsing  pattern, which must parse the CSV date value completely.  Some
+       examples:
+
+              # MM/DD/YY
+              date-format %m/%d/%y
+
+              # D/M/YYYY
+              # The - makes leading zeros optional.
+              date-format %-d/%-m/%Y
+
+              # YYYY-Mmm-DD
+              date-format %Y-%h-%d
+
+              # M/D/YYYY HH:MM AM some other junk
+              # Note the time and junk must be fully parsed, though only the date is used.
+              date-format %-m/%-d/%Y %l:%M %p some other junk
+
+       For the supported strptime syntax, see:
+       https://hackage.haskell.org/package/time/docs/Data-Time-For-
+       mat.html#v:formatTime
+
+       Note  that although you can parse date-times which include a time zone,
+       that time zone is ignored; it will not change the date that is  parsed.
+       This  means  when  reading  CSV  data with times not in your local time
+       zone, dates can be "off by one".
+
+   decimal-mark
+              decimal-mark .
+
+       or:
+
+              decimal-mark ,
+
+       hledger automatically accepts either period or comma as a decimal  mark
+       when  parsing  numbers (cf Amounts).  However if any numbers in the CSV
+       contain digit group marks,  such  as  thousand-separating  commas,  you
+       should  declare  the  decimal  mark explicitly with this rule, to avoid
+       misparsed numbers.
+
+   newest-first
+       hledger always sorts the generated transactions by date.   Transactions
+       on  the same date should appear in the same order as their CSV records,
+       as hledger can usually auto-detect whether the CSV's  normal  order  is
+       oldest first or newest first.  But if all of the following are true:
+
+       o the  CSV  might  sometimes  contain just one day of data (all records
+         having the same date)
+
+       o the CSV records are normally in reverse chronological  order  (newest
+         at the top)
+
+       o and you care about preserving the order of same-day transactions
+
+       then, you should add the newest-first rule as a hint.  Eg:
+
+              # tell hledger explicitly that the CSV is normally newest first
+              newest-first
+
+   include
+              include RULESFILE
+
+       This  includes  the  contents  of another CSV rules file at this point.
+       RULESFILE is an absolute file path or a path relative  to  the  current
+       file's  directory.  This can be useful for sharing common rules between
+       several rules files, eg:
+
+              # someaccount.csv.rules
+
+              ## someaccount-specific rules
+              fields   date,description,amount
+              account1 assets:someaccount
+              account2 expenses:misc
+
+              ## common rules
+              include categorisation.rules
+
+   balance-type
+       Balance assertions generated by assigning to balanceN are of the simple
+       =  type  by  default, which is a single-commodity, subaccount-excluding
+       assertion.  You may find the subaccount-including variants more useful,
+       eg  if  you  have  created some virtual subaccounts of checking to help
+       with budgeting.  You can select a different type of assertion with  the
+       balance-type rule:
+
+              # balance assertions will consider all commodities and all subaccounts
+              balance-type ==*
+
+       Here are the balance assertion types for quick reference:
+
+              =    single commodity, exclude subaccounts
+              =*   single commodity, include subaccounts
+              ==   multi commodity,  exclude subaccounts
+              ==*  multi commodity,  include subaccounts
+
+   Tips
+   Rapid feedback
+       It's  a  good idea to get rapid feedback while creating/troubleshooting
+       CSV rules.  Here's a good way, using entr from http://eradman.com/entr-
+       project :
+
+              $ ls foo.csv* | entr bash -c 'echo ----; hledger -f foo.csv print desc:SOMEDESC'
+
+       A  desc:  query (eg) is used to select just one, or a few, transactions
+       of interest.  "bash -c" is used to run multiple  commands,  so  we  can
+       echo  a  separator  each  time the command re-runs, making it easier to
+       read the output.
+
+   Valid CSV
+       hledger accepts CSV conforming  to  RFC  4180.   When  CSV  values  are
+       enclosed in quotes, note:
+
+       o they must be double quotes (not single quotes)
+
+       o spaces outside the quotes are not allowed

+       To  help hledger identify the format and show the right error messages,
+       CSV/SSV/TSV files should normally be named with a .csv,  .ssv  or  .tsv
+       filename  extension.   Or,  the file path should be prefixed with csv:,
+       ssv: or tsv:.  Eg:
+
+              $ hledger -f foo.ssv print
+
+       or:
+
+              $ cat foo | hledger -f ssv:- foo
+
+       You can override the file extension with a separator  rule  if  needed.
+       See also: Input files in the hledger manual.
+
+   Reading multiple CSV files
+       If  you  use  multiple  -f  options to read multiple CSV files at once,
+       hledger will look for a correspondingly-named rules file for  each  CSV
+       file.   But if you use the --rules-file option, that rules file will be
+       used for all the CSV files.
+
+   Valid transactions
+       After reading a CSV file, hledger post-processes and validates the gen-
+       erated journal entries as it would for a journal file - balancing them,
+       applying balance assignments, and canonicalising  amount  styles.   Any
+       errors  at this stage will be reported in the usual way, displaying the
+       problem entry.
+
+       There is one exception: balance assertions, if you have generated them,
+       will  not  be checked, since normally these will work only when the CSV
+       data is part of the main journal.  If you  do  need  to  check  balance
+       assertions generated from CSV right away, pipe into another hledger:
+
+              $ hledger -f file.csv print | hledger -f- print
+
+   Deduplicating, importing
+       When  you  download a CSV file periodically, eg to get your latest bank
+       transactions, the new file may overlap with  the  old  one,  containing
+       some of the same records.
+
+       The import command will (a) detect the new transactions, and (b) append
+       just those transactions to your main journal.  It is idempotent, so you
+       don't  have to remember how many times you ran it or with which version
+       of the CSV.  (It keeps state in a hidden .latest.FILE.csv  file.)  This
+       is the easiest way to import CSV data.  Eg:
+
+              # download the latest CSV files, then run this command.
+              # Note, no -f flags needed here.
+              $ hledger import *.csv [--dry]
+
+       This  method  works  for  most CSV files.  (Where records have a stable
+       chronological order, and new records appear only at the new end.)
+
+       A number of other tools and workflows, hledger-specific and  otherwise,
+       exist for converting, deduplicating, classifying and managing CSV data.
+       See:

+
+   Setting amounts
+       Some tips on using the amount-setting rules discussed above.
+
+       Here are the ways to set a posting's amount:
+
+       1. If the CSV has a single amount field:
+       Assign (via a fields list or a field assignment) to amountN.  This sets
+       the Nth posting's amount.  N is usually 1 or 2 but can go up to 99.
+
+       2. If the CSV has separate amount fields for debit & credit (in & out):
+
+           a. If both fields are unsigned:
+           Assign to amountN-in and amountN-out.  This sets posting N's amount
+           to  whichever of these has a non-zero value, and negates the "-out"
+           value.
+
+           b. If either field is signed (can contain a minus sign):
+           Use a conditional rule to flip  the  sign  (of  non-empty  values).
+           Since  hledger  always negates amountN-out, if it was already nega-
+           tive, we must undo that by negating once  more  (but  only  if  the
+           field is non-empty):
+
+                  fields date, description, amount1-in, amount1-out
+                  if %amount1-out [1-9]
+                   amount1-out -%amount1-out
+
+           c. If both fields, or neither field, can contain a non-zero value:
+           hledger  normally  expects exactly one of the fields to have a non-
+           zero value.  Eg,  the  amountN-in/amountN-out  rules  would  reject
+           value pairs like these:
+
+                  "",  ""
+                  "0", "0"
+                  "1", "none"
+
+           So, use smarter conditional rules to set the amount from the appro-
+           priate field.  Eg, these rules would make it  use  only  the  value
+           containing non-zero digits, handling the above:
+
+                  fields date, description, in, out
+                  if %in [1-9]
+                   amount1 %in
+                  if %out [1-9]
+                   amount1 %out
+
+       3. If  you are stuck with hledger <1.17, or you want posting 2's amount
+          converted to cost:
+       Assign to amount (or to amount-in and amount-out).  (The old numberless
+       syntax, which sets amount1 and amount2.)
+
+       4. If the CSV has the balance instead of the transaction amount:
+       Assign to balanceN, which sets posting N's amount indirectly via a bal-
+       ance assignment.  (Old syntax: balance, equivalent to balance1.)
+
+           o If hledger guesses the wrong default account name:
+           When setting the amount via balance assertion,  hledger  may  guess
+           the  wrong  default account name.  So, set the account name explic-
+           itly, eg:
+
+                    fields date, description, balance1
+                    account1 assets:checking
+
+   Amount signs
+       There is some special handling for amount signs,  to  simplify  parsing
+       and sign-flipping:
+
+       o If an amount value begins with a plus sign:
+       that will be removed: +AMT becomes AMT
+
+       o If an amount value is parenthesised:
+       it will be de-parenthesised and sign-flipped: (AMT) becomes -AMT
+
+       o If  an  amount value has two minus signs (or two sets of parentheses,
+         or a minus sign and parentheses):
+       they cancel out and will be removed: --AMT or -(AMT) becomes AMT
+
+       o If an amount value contains just a sign (or just a set  of  parenthe-
+         ses):
+       that  is removed, making it an empty value.  "+" or "-" or "()" becomes
+       "".
+
+   Setting currency/commodity
+       If the currency/commodity  symbol  is  included  in  the  CSV's  amount
+       field(s):
+
+              2020-01-01,foo,$123.00
+
+       you don't have to do anything special for the commodity symbol, it will
+       be assigned as part of the amount.  Eg:
+
+              fields date,description,amount
+
+              2020-01-01 foo
+                  expenses:unknown         $123.00
+                  income:unknown          $-123.00
+
+       If the currency is provided as a separate CSV field:
+
+              2020-01-01,foo,USD,123.00
+
+       You can assign that to the currency pseudo-field, which has the special
+       effect  of prepending itself to every amount in the transaction (on the
+       left, with no separating space):
+
+              fields date,description,currency,amount
+
+              2020-01-01 foo
+                  expenses:unknown       USD123.00
+                  income:unknown        USD-123.00
+
+       Or, you can use a field assignment to construct  the  amount  yourself,
+       with more control.  Eg to put the symbol on the right, and separated by
+       a space:
+
+              fields date,description,cur,amt
+              amount %amt %cur
+
+              2020-01-01 foo
+                  expenses:unknown        123.00 USD
+                  income:unknown         -123.00 USD
+
+       Note we used a temporary field name (cur) that is not currency  -  that
+       would trigger the prepending effect, which we don't want here.
+
+   Amount decimal places
+       Like amounts in a journal file, the amounts generated by CSV rules like
+       amount1 influence commodity display styles, such as the number of deci-
+       mal places displayed in reports.
+
+       The  original  amounts as written in the CSV file do not affect display
+       style (because we don't yet reliably know their commodity).
+
+   Referencing other fields
+       In field assignments, you can interpolate only CSV fields, not  hledger
+       fields.   In  the example below, there's both a CSV field and a hledger
+       field named amount1, but %amount1 always means the CSV field,  not  the
+       hledger field:
+
+              # Name the third CSV field "amount1"
+              fields date,description,amount1
+
+              # Set hledger's amount1 to the CSV amount1 field followed by USD
+              amount1 %amount1 USD
+
+              # Set comment to the CSV amount1 (not the amount1 assigned above)
+              comment %amount1
+
+       Here,  since there's no CSV amount1 field, %amount1 will produce a lit-
+       eral "amount1":
+
+              fields date,description,csvamount
+              amount1 %csvamount USD
+              # Can't interpolate amount1 here
+              comment %amount1
+
+       When there are multiple field assignments to the  same  hledger  field,
+       only the last one takes effect.  Here, comment's value will be be B, or
+       C if "something" is matched, but never A:
+
+              comment A
+              comment B
+              if something
+               comment C
+
+   How CSV rules are evaluated
+       Here's how to think of CSV rules being evaluated (if  you  really  need
+       to).  First,
+
+       o include  - all includes are inlined, from top to bottom, depth first.
+         (At each include point the file is inlined and  scanned  for  further
+         includes, recursively, before proceeding.)
+
+       Then  "global"  rules  are  evaluated,  top  to  bottom.   If a rule is
+       repeated, the last one wins:
+
+       o skip (at top level)
+
+       o date-format
+
+       o newest-first
+
+       o fields - names the CSV fields, optionally sets up initial assignments
+         to hledger fields
+
+       Then for each CSV record in turn:
+
+       o test  all  if  blocks.   If  any of them contain a end rule, skip all
+         remaining CSV records.  Otherwise if any of them contain a skip rule,
+         skip  that  many  CSV  records.   If  there are multiple matched skip
+         rules, the first one wins.
+
+       o collect all field assignments at top level and in matched if  blocks.
+         When  there  are multiple assignments for a field, keep only the last
+         one.
+
+       o compute a value for each hledger field -  either  the  one  that  was
+         assigned  to  it (and interpolate the %CSVFIELDNAME references), or a
+         default
+
+       o generate a synthetic hledger transaction from these values.
+
+       This is all part of the CSV reader, one of several readers hledger  can
+       use  to parse input files.  When all files have been read successfully,
+       the transactions are passed as input to whichever hledger  command  the
+       user specified.
+
+TIMECLOCK FORMAT
+       The time logging format of timeclock.el, as read by hledger.
+
+       hledger  can read time logs in timeclock format.  As with Ledger, these
+       are (a subset of) timeclock.el's format, containing clock-in and clock-
+       out  entries  as in the example below.  The date is a simple date.  The
+       time format is HH:MM[:SS][+-ZZZZ].  Seconds and timezone are  optional.
+       The timezone, if present, must be four digits and is ignored (currently
+       the time is always interpreted as a local time).
+
+              i 2015/03/30 09:00:00 some:account name  optional description after two spaces
+              o 2015/03/30 09:20:00
+              i 2015/03/31 22:21:45 another account
+              o 2015/04/01 02:00:34
+
+       hledger treats each clock-in/clock-out pair as  a  transaction  posting
+       some  number of hours to an account.  Or if the session spans more than
+       one day, it is split into several transactions, one for each day.   For
+       the above time log, hledger print generates these journal entries:
+
+              $ hledger -f t.timeclock print
+              2015-03-30 * optional description after two spaces
+                  (some:account name)         0.33h
+
+              2015-03-31 * 22:21-23:59
+                  (another account)         1.64h
+
+              2015-04-01 * 00:00-02:00
+                  (another account)         2.01h
+
+       Here is a sample.timeclock to download and some queries to try:
+
+              $ hledger -f sample.timeclock balance                               # current time balances
+              $ hledger -f sample.timeclock register -p 2009/3                    # sessions in march 2009
+              $ hledger -f sample.timeclock register -p weekly --depth 1 --empty  # time summary by week
+
+       To generate time logs, ie to clock in and clock out, you could:
+
+       o use  emacs  and the built-in timeclock.el, or the extended timeclock-
+         x.el and perhaps the extras in ledgerutils.el
+
+       o at the command line, use these bash aliases: shell     alias ti="echo
+         i  `date  '+%Y-%m-%d  %H:%M:%S'` \$* >>$TIMELOG"     alias to="echo o
+         `date '+%Y-%m-%d %H:%M:%S'` >>$TIMELOG"
+
+       o or use the old ti and to scripts in the ledger 2.x repository.  These
+         rely  on  a "timeclock" executable which I think is just the ledger 2
+         executable renamed.
+
+TIMEDOT FORMAT
+       timedot format is hledger's human-friendly time logging  format.   Com-
+       pared to timeclock format, it is
+
+       o convenient for quick, approximate, and retroactive time logging
+
+       o readable: you can see at a glance where time was spent.
+
+       A  timedot file contains a series of day entries, which might look like
+       this:
+
+              2021-08-04
+              hom:errands          .... ....
+              fos:hledger:timedot  ..         ; docs
+              per:admin:finance
+
+       hledger reads this as three time transactions on this  day,  with  each
+       dot representing a quarter-hour spent:
+
+              $ hledger -f a.timedot print   # .timedot file extension activates the timedot reader
+              2021-08-04 *
+                  (hom:errands)            2.00
+
+              2021-08-04 *
+                  (fos:hledger:timedot)    0.50
+
+              2021-08-04 *
+                  (per:admin:finance)      0
+
+       A day entry begins with a date line:
+
+       o a non-indented simple date (Y-M-D, Y/M/D, or Y.M.D).
+
+       Optionally this can be followed on the same line by
+
+       o a common transaction description for this day
+
+       o a common transaction comment for this day, after a semicolon (;).
+
+       After  the date line are zero or more optionally-indented time transac-
+       tion lines, consisting of:
+
+       o an account name - any word or phrase, usually a hledger-style account
+         name.
+
+       o two  or  more  spaces  -  a  field separator, required if there is an
+         amount (as in journal format).
+
+       o a timedot amount - dots representing quarter hours, or a number  rep-
+         resenting hours.
+
+       o an optional comment beginning with semicolon.  This is ignored.
+
+       In more detail, timedot amounts can be:
+
+       o dots:  zero or more period characters, each representing one quarter-
+         hour.  Spaces are ignored and can be used for grouping.  Eg: ....  ..
+
+       o a number, representing hours.  Eg: 1.5
+
+       o a  number immediately followed by a unit symbol s, m, h, d, w, mo, or
+         y, representing seconds, minutes, hours, days weeks, months or years.
+         Eg 1.5h or 90m.  The following equivalencies are assumed:
+       60s  =  1m,  60m  = 1h, 24h = 1d, 7d = 1w, 30d = 1mo, 365d = 1y.  (This
+       unit will not be visible in the generated transaction amount, which  is
+       always in hours.)
+
+       There  is  some added flexibility to help with keeping time log data in
+       the same file as your notes, todo lists, etc.:
+
+       o Lines beginning with # or ;, and blank lines, are ignored.
+
+       o Lines not ending with a double-space and amount are parsed as  trans-
+         actions  with  zero  amount.   (Most  hledger  reports  hide these by
+         default; add -E to see them.)
+
+       o One or more stars (*) followed by a space, at the start of a line, is
+         ignored.   So  date  lines or time transaction lines can also be Org-
+         mode headlines.
+
+       o All Org-mode headlines before the first date line are ignored.

+
+   Constructing command lines
+       hledger has an extensive  and  powerful  command  line  interface.   We
+       strive to keep it simple and ergonomic, but you may run into one of the
+       confusing real world details described in OPTIONS, below.  If that hap-
+       pens, here are some tips that may help:
+
+       o command-specific  options must go after the command (it's fine to put
+         all options there) (hledger CMD OPTS ARGS)
+
+       o running add-on executables directly simplifies command  line  parsing
+         (hledger-ui OPTS ARGS)
+
+       o enclose "problematic" args in single quotes
+
+       o if  needed, also add a backslash to hide regular expression metachar-
+         acters from the shell
+
+       o to see how a misbehaving command is being parsed, add --debug=2.
+
+   Starting a journal file
+       hledger  looks  for  your  accounting   data   in   a   journal   file,
+       $HOME/.hledger.journal by default:
+
+              $ hledger stats
+              The hledger journal file "/Users/simon/.hledger.journal" was not found.
+              Please create it first, eg with "hledger add" or a text editor.
+              Or, specify an existing journal file with -f or LEDGER_FILE.
+
+       You  can override this by setting the LEDGER_FILE environment variable.
+       It's a good practice to keep this important file under version control,
+       and  to  start  a  new  file each year.  So you could do something like
+       this:
+
+              $ mkdir ~/finance
+              $ cd ~/finance
+              $ git init
+              Initialized empty Git repository in /Users/simon/finance/.git/
+              $ touch 2020.journal
+              $ echo "export LEDGER_FILE=$HOME/finance/2020.journal" >> ~/.bashrc
+              $ source ~/.bashrc
+              $ hledger stats
+              Main file                : /Users/simon/finance/2020.journal
+              Included files           :
+              Transactions span        :  to  (0 days)
+              Last transaction         : none
+              Transactions             : 0 (0.0 per day)
+              Transactions last 30 days: 0 (0.0 per day)
+              Transactions last 7 days : 0 (0.0 per day)
+              Payees/descriptions      : 0
+              Accounts                 : 0 (depth 0)
+              Commodities              : 0 ()
+              Market prices            : 0 ()
+
+   Setting opening balances
+       Pick a starting date for which you can look up  the  balances  of  some
+       real-world  assets  (bank  accounts,  wallet..) and liabilities (credit
+       cards..).
+
+       To avoid a lot of data entry, you may want to start with  just  one  or
+       two  accounts,  like  your  checking account or cash wallet; and pick a
+       recent starting date, like today or the start of  the  week.   You  can
+       always come back later and add more accounts and older transactions, eg
+       going back to january 1st.
+
+       Add an opening balances transaction to the journal, declaring the  bal-
+       ances on this date.  Here are two ways to do it:
+
+       o The  first way: open the journal in any text editor and save an entry
+         like this:
+
+                2020-01-01 * opening balances
+                    assets:bank:checking                $1000   = $1000
+                    assets:bank:savings                 $2000   = $2000
+                    assets:cash                          $100   = $100
+                    liabilities:creditcard               $-50   = $-50
+                    equity:opening/closing balances
+
+         These are start-of-day balances, ie whatever was in  the  account  at
+         the end of the previous day.
+
+         The  *  after  the  date  is  an optional status flag.  Here it means
+         "cleared & confirmed".
+
+         The currency symbols are optional, but usually a good idea as  you'll
+         be dealing with multiple currencies sooner or later.
+
+         The  = amounts are optional balance assertions, providing extra error
+         checking.
+
+       o The second way: run hledger add and follow the prompts  to  record  a
+         similar transaction:
+
+                $ hledger add
+                Adding transactions to journal file /Users/simon/finance/2020.journal
+                Any command line arguments will be used as defaults.
+                Use tab key to complete, readline keys to edit, enter to accept defaults.
+                An optional (CODE) may follow transaction dates.
+                An optional ; COMMENT may follow descriptions or amounts.
+                If you make a mistake, enter < at any prompt to go one step backward.
+                To end a transaction, enter . when prompted.
+                To quit, enter . at a date prompt or press control-d or control-c.
+                Date [2020-02-07]: 2020-01-01
+                Description: * opening balances
+                Account 1: assets:bank:checking
+                Amount  1: $1000
+                Account 2: assets:bank:savings
+                Amount  2 [$-1000]: $2000
+                Account 3: assets:cash
+                Amount  3 [$-3000]: $100
+                Account 4: liabilities:creditcard
+                Amount  4 [$-3100]: $-50
+                Account 5: equity:opening/closing balances
+                Amount  5 [$-3050]:
+                Account 6 (or . or enter to finish this transaction): .
+                2020-01-01 * opening balances
+                    assets:bank:checking                      $1000
+                    assets:bank:savings                       $2000
+                    assets:cash                                $100
+                    liabilities:creditcard                     $-50
+                    equity:opening/closing balances          $-3050
+
+                Save this transaction to the journal ? [y]:
+                Saved.
+                Starting the next transaction (. or ctrl-D/ctrl-C to quit)
+                Date [2020-01-01]: .
+
+       If  you're  using  version control, this could be a good time to commit
+       the journal.  Eg:
+
+              $ git commit -m 'initial balances' 2020.journal
+
+   Recording transactions
+       As you spend or receive money, you can record these transactions  using
+       one  of  the  methods  above (text editor, hledger add) or by using the
+       hledger-iadd or hledger-web add-ons, or by using the import command  to
+       convert CSV data downloaded from your bank.
+
+       Here  are  some  simple transactions, see the hledger_journal(5) manual
+       and hledger.org for more ideas:
+
+              2020/1/10 * gift received
+                assets:cash   $20
+                income:gifts
+
+              2020.1.12 * farmers market
+                expenses:food    $13
+                assets:cash
+
+              2020-01-15 paycheck
+                income:salary
+                assets:bank:checking    $1000
+
+   Reconciling
+       Periodically you should reconcile - compare your hledger-reported  bal-
+       ances  against  external sources of truth, like bank statements or your
+       bank's website - to be sure that your ledger accurately represents  the
+       real-world  balances  (and,  that  the real-world institutions have not
+       made a mistake!).  This gets easy and fast with (1)  practice  and  (2)
+       frequency.   If  you do it daily, it can take 2-10 minutes.  If you let
+       it pile up, expect it to take longer as you hunt down errors  and  dis-
+       crepancies.
+
+       A typical workflow:
+
+       1. Reconcile  cash.   Count  what's  in your wallet.  Compare with what
+          hledger reports (hledger bal cash).  If they are different,  try  to
+          remember  the  missing  transaction,  or  look  for the error in the
+          already-recorded transactions.  A register  report  can  be  helpful
+          (hledger  reg cash).  If you can't find the error, add an adjustment
+          transaction.  Eg if you have $105 after the above, and can't explain
+          the missing $2, it could be:
+
+                  2020-01-16 * adjust cash
+                      assets:cash    $-2 = $105
+                      expenses:misc
+
+       2. Reconcile checking.  Log in to your bank's website.  Compare today's
+          (cleared) balance with hledger's cleared balance (hledger bal check-
+          ing  -C).  If they are different, track down the error or record the
+          missing transaction(s) or add an adjustment transaction, similar  to
+          the above.  Unlike the cash case, you can usually compare the trans-
+          action history and running balance  from  your  bank  with  the  one
+          reported  by  hledger  reg  checking -C.  This will be easier if you
+          generally record transaction dates  quite  similar  to  your  bank's
+          clearing dates.
+
+       3. Repeat for other asset/liability accounts.
+
+       Tip:  instead  of  the  register command, use hledger-ui to see a live-
+       updating register while you edit the journal: hledger-ui --watch --reg-
+       ister checking -C
+
+       After  reconciling,  it  could  be  a  good time to mark the reconciled
+       transactions' status as "cleared and confirmed", if you want  to  track
+       that,  by  adding  the * marker.  Eg in the paycheck transaction above,
+       insert * between 2020-01-15 and paycheck
+
+       If you're using version control, this can be another good time to  com-
+       mit:
+
+              $ git commit -m 'txns' 2020.journal

+
+   Migrating to a new file
+       At the end of the year, you may want to continue your journal in a  new
+       file, so that old transactions don't slow down or clutter your reports,
+       and to help ensure the integrity of your accounting history.   See  the
+       close command.
+
+       If using version control, don't forget to git add the new file.
+
+LIMITATIONS
+       The  need  to  precede add-on command options with -- when invoked from
+       hledger is awkward.
+
+       When input data contains non-ascii characters, a suitable system locale
+       must be configured (or there will be an unhelpful error).  Eg on POSIX,
+       set LANG to something other than C.
+
+       In a Microsoft Windows CMD window, non-ascii characters and colours are
+       not supported.
+
+       On Windows, non-ascii characters may not display correctly when running
+       a hledger built in CMD in MSYS/CYGWIN, or vice-versa.
+
+       In a Cygwin/MSYS/Mintty window, the tab key is not supported in hledger
+       add.
+
+       Not  all of Ledger's journal file syntax is supported.  See file format
+       differences.
+
+       On large data files, hledger  is  slower  and  uses  more  memory  than
+       Ledger.
+
+TROUBLESHOOTING
+       Here  are  some  issues  you  might encounter when you run hledger (and
+       remember you can also seek help from the IRC channel, mail list or  bug
+       tracker):
+
+       Successfully installed, but "No command 'hledger' found"
+       stack and cabal install binaries into a special directory, which should
+       be added to your PATH environment variable.  Eg on  unix-like  systems,
+       that is ~/.local/bin and ~/.cabal/bin respectively.
+
+       I set a custom LEDGER_FILE, but hledger is still using the default file
+       LEDGER_FILE should be a real environment variable,  not  just  a  shell
+       variable.   The command env | grep LEDGER_FILE should show it.  You may
+       need to use export.  Here's an explanation.
+
+       Getting errors like "Illegal byte sequence" or "Invalid  or  incomplete
+       multibyte  or wide character" or "commitAndReleaseBuffer: invalid argu-
+       ment (invalid character)"
+       Programs compiled with GHC (hledger, haskell build tools, etc.) need to
+       have a UTF-8-aware locale configured in the environment, otherwise they
+       will fail with these kinds of  errors  when  they  encounter  non-ascii
+       characters.
+
+       To  fix it, set the LANG environment variable to some locale which sup-
+       ports UTF-8.  The locale you choose must be installed on your system.
+
+       Here's an example of setting LANG temporarily, on Ubuntu GNU/Linux:
+
+              $ file my.journal
+              my.journal: UTF-8 Unicode text         # the file is UTF8-encoded
+              $ echo $LANG
+              C                                      # LANG is set to the default locale, which does not support UTF8
+              $ locale -a                            # which locales are installed ?
+              C
+              en_US.utf8                             # here's a UTF8-aware one we can use
+              POSIX
+              $ LANG=en_US.utf8 hledger -f my.journal print   # ensure it is used for this command
+
+       If available, C.UTF-8 will also work.  If your preferred  locale  isn't
+       listed   by   locale   -a,  you  might  need  to  install  it.   Eg  on
+       Ubuntu/Debian:
+
+              $ apt-get install language-pack-fr
+              $ locale -a
+              C
+              en_US.utf8
+              fr_BE.utf8
+              fr_CA.utf8
+              fr_CH.utf8
+              fr_FR.utf8
+              fr_LU.utf8
+              POSIX
+              $ LANG=fr_FR.utf8 hledger -f my.journal print
+
+       Here's how you could set it permanently, if you use a bash shell:
+
+              $ echo "export LANG=en_US.utf8" >>~/.bash_profile
+              $ bash --login
+
+       Exact spelling and capitalisation may be important.  Note  the  differ-
+       ence  on  MacOS  (UTF-8,  not  utf8).  Some platforms (eg ubuntu) allow
+       variant spellings, but others (eg macos) require it to be exact:
+
+              $ locale -a | grep -iE en_us.*utf
+              en_US.UTF-8
+              $ LANG=en_US.UTF-8 hledger -f my.journal print
