# Revision history for skylighting and skylighting-core
## 0.13
* Update syntax definitions from upstream: bash, cmake, diff,
ini, perl, php, sgml, xml.
* Split out formatters into separate packages (#152). API changes:
- Skylighting.Core no longer exports Skylighting.Format.ANSI,
Skylighting.Format.HTML, Skylighting.Format.LaTeX. These are
now provided by separate packages, skylighting-format-ansi,
skylighting-format-blaze-html, skylighting-format-latex.
- Skylighting.Types no longer exports XTerm256ColorCode.
This has been moved to skylighting-format-ansi.
* Change Makefile to use cabal instead of stack.
## 0.12.3.1
* Allow mtl 2.3.
* Update syntax defs from upstream: bash, cmake, go, haxe, lua, zsh.
* Add nix.xml (#149).
* Add Pygments styles for `Import` and `BuiltIn` token types (#147,
Bryan A. Danielak).
* Use StrictData.
* Remove unused dependencies (silences cabal warnings) (Andreas Abel).
## 0.12.3
* Add scss, sass, systemverilog, orgmode.
* Update xml definitions from upstream: bash, css, python, r, zsh.
## 0.12.2
* Parser: handle context shift to external context, e.g.,
`BashOneLine##Bash`. Closes #139 (issue with Dockerfile).
* Update xml files from upstream:
bash, cmake, markdown, objectivecpp, php, sql-postgresql, sql, stan, zshr
* Fix formatting in `Color` doc-comment (Janek Spaderna).
* Add stan.xml (Brian Ward).
## 0.12.1
* Update syntax definitions: bash, cmake, dockerfile,
gnuassembler, markdown, spdx-comments.
* Support hex escapes using `\x` in regex char classes (#135).
These occur in a number of syntax definitions and weren't
correctly interpreted before. Thanks to @Agnishom.
* Support regex property syntax, e.g. `\p{Lu}`.
* Regex: support `\B` (non-word-boundary).
## 0.12
* Properly handle include elements in keyword lists (#124).
A number of syntaxes (e.g. typescript, scala) include keyword
lists from other syntaxe,s and previously we weren't able to
handle this.
There are several pieces to this change. We need to store lists
where other Syntaxes can look them up, so we add an `sLists`
field to `Syntax` [API change], and modify the parser to fill this.
We change lists so that their values are not just a `Text`, but a
`ListItem` that can either be a textual value or an include directive,
specifying a `ListName` (syntax name and list name).
The `Keyword` constructor for `Matcher` now takes, instead of a
`WordSet`, Either a `ListName` or a `WordSet` (API change).
Skylighting.Parser now exports `resolveKeywords` (API change),
which modifies all `Keyword` matchers in a syntax so that Left
values with a `ListName` become Right values with resolved `WordSet`s.
The tokenizer applies this function automatically to the SyntaxMap
given in Config. But it is more efficient to do this conversion
just once, rather than every time `tokenize` is called. So we have
`loadSyntaxesFromDir` call it on the `SyntaxMap`. With this
optimization, there is not an appreciable performance cost to the
changes described above.
* Skylighting.Regex: Fix bug with regexes like `a{10}b` (#133).
This requires exactly 10 a's; previously we interpreted it as
"at least 10."
* skylighting-extract: take a directory as argument rather than files.
This allows us to use `loadSyntaxesFromDir`.
* Update xml syntax definitions from upstream:
julia, cmake, cpp, isocpp, markdown, python, toml.
## 0.11
* Skylighting.Regex: Support regex subroutines (#118). For example,
`(?1)` is replaced by the regex in the first capturing group. So far
we only support this simple, absolute form, not the relative
form `(?-1)` supported by some engines (but not used, I think, in
KDE's syntax highlighters). This change involves an API change:
Regex in Skylighting.Regex has a new Subroutine constructor,
and the Recurse constructor has been removed. Instead of Recurse we use
Subroutine 0, which unifies the code.
* Skylighting.Regex: handle e.g. `[\1]` and `[\123]` (without
initial 0) as octal escapes (#118). These occur in the zsh.xml
syntax definition.
* Pull xml definitions for bash, cmake, python, zsh from upstream.
* README: Add a note about pulling syntax definitions from upstream (#138).
Update build instructions for recent cabal versions (#131).
## 0.10.5.2
* Added swift grammar definition (Igor Ranieri).
* Simplify README.md instructions for two-step build.
* Fix link to KDE documentation.
## 0.10.5.1
* Regex: Allow lookaheads to capture groups. Previously
captures in lookaheads, like `(?=(a*))`, were ignored. This
led to errors highlighting xml and probably other formats (#121).
* Throw an exception if a capture group isn't defined (with 'dynamic')
rather than simply having getCapture fail so that the rule fails.
This will make it easier to debug issues like #121.
## 0.10.5
* Fix regression from 0.10.3 with Haskell highlighting of Char (#120).
* Update xml syntax definitions from upstream. Updated
syntaxes: abc apache asp bash bibtex boo c changelog clojure
cmake commonlisp cs curry d diff djangotemplate doxygen
elixir elm email erlang fortran-fixed fortran-free fsharp
hamlet haskell haxe html idris ini javascript-react

sql-postgresql tcl tcsh toml typescript verilog xml xslt xul
yacc yaml. Not updated: rhtml (causes an error on our test
suite), zsh (has a regex we can't parse).
## 0.10.4.1
* Fixed logic for checking line-end-context (#119).
* Use NonEmpty for the context stack.
* Remove unneeded build-depends.
## 0.10.4
* Move from hxt to xml-conduit for XML parsing.
This gives about a 4X speedup in parsing syntax definitions.
It also reduces the pandoc build dependency footprint, as we
depend on xml-conduit anyway and now no longer need to compile
HXT and its dependencies.
There are improvements in accuracy as well: the change to
xml-conduit improved parsing for one of the prolog rules;
a matcher that should have been for tab characters had been set for a
space instead.
* Removed some unnecessary build-depends in skylighting-extract.
## 0.10.3
* Add support for raku (#114).
* Reimplement PR #40 and add haskell.xml.patch (#116).
* Update syntax definitions: actionscript ada asp awk bash

xml, xorg, xul.
* Re-insert CSS line needed to make line numbers appear in
HTML. See jgm/pandoc#6625.
## 0.10.1
* Regex: handle `(?|)` modifier. This is used in bash.xml now.
It resets the numbers of capturing groups in alternatives.
* Improve regex handling of `{` and `}` not in quantifiers:
- `{}` is literal (not a quantifier).
- loose unescaped `{` and `}` that are not part of a quantifier are
literal matchers.
* Update xml syntax definitions from upstream.
For: abc, actionscript, ada, agda, alert, apache, asn1, asp,
ats, awk, bash, boo, c, clojure, cmake, coffee, coldfusion,

Also added spdx-comments.xml and comments.xml, which are
needed for these. Closes #111 (latex bug in matrix).
## 0.10.0.3
* Add groovy syntax.
## 0.10.0.2
* Improve DetectIdentifier to ensure that identifiers can't
include non-ASCII characters.
## 0.10.0.1
* Fix identifier detection in non-ASCII context (#110).
## 0.10
* Add instructions for submitting patches upstream to KDE (#106).
* Synced syntax definitions from KDE repo. Note that fortran
has split into two: `fortran-fixed` and `fortran-free`.
* Add test to ensure that all regexes in rules compile.
* Regex: allow unescaped `}`.
* Regex: allow empty regexes and groups.
* Regex: support lazy and possessive quantifiers (#109).
* Regex: support recursive regexes `(?R)` (#108).
* Hide invisible line numbers from keyboard focus (#107, d10n).
This fixes tabbing through elements on a page.
* Remove some obsolete patches for xml definitions.
## 0.9
* Use a pure Haskell regex implementation (in unexported module
Text.Regex.KDE) instead of pcre. The implementation is not
as efficient as pcre, but it seems good enough for this
application, and it is desirable to avoid depending on a C
library. (Available Haskell libraries weren't up to the
task, because they don't do back-references, captures,
lookahead/behind.) Some benchmarks (old/new):
haskell (4.6/7.9) java (13.4/23.3) c (2.8/3.7) rhtml
(4.7/6.1) lua (10.6/13.2) javascript (4.2/6.6).
Though this is a significant slowdown, the tradeoff seems
worth it to have a pure Haskell implementation.
* Removed old `system-pcre` flag.
* More efficient treatment of dynamic regexes.
We put something in the Regex itself to represent the `%1`,
and modify it later. This allows us to cache dynamic
regexes in a way we couldn't before.
* Add support for TOML (#105, Shiming Wang),
GraphQL, and Nim syntax (#102, Daniel Pozo Escalona).
* Update xml definitions for actionscript, bash, boo, c,
cmake, elm, erlang, glsl, isocpp, java, lua, m4, mediawiki,
perl, powershell, scala, tcsh, xul, zsh.
* Fix fallthrough behavior (don't always consume a token).
* Fix word boundary detection.
* Remove RegexException. (API change)
* Skylighting.Regex now exports `isWordChar` and `testRegex`,
as well as the constructors underlying the new `Regex` type.
* Remove some obsolete xml definition patches.
* Fix escaped % in dynamic regex.
## 0.8.5
* Respect dynamic flag on StringDetect elements (#99, Albert
Krewinkel).
* Increase test timeout to avoid failures with qemu-emulated
environments, such as qemu and riscv64 in Ubuntu builders
(William Grant).
* Fix attribute for opening double quote in sql-postgresql.xml
(Benjamin Wuethrich).
* Update syntax descriptions for javascript, bash, coffee,
javascript-react, javascript, latex, sql-postgresql, typescript.
## 0.8.4
* HTML output: use aria-hidden="true" on empty a elements
unless numberLines is specified (in which case the element
is still empty but will have content added by CSS).
This is to avoid excess noise when the code blocks are
read by screen readers. See jgm/pandoc#6352.
## 0.8.3.4
* Update syntax descriptions for: cmake agda c coffee doxygenlua html
isocpp latex lua makefile markdown metafont mustache nasm python rust
sql-postgresql typescript vhdl xml yacc yaml.
* Fix invalid CSS: in some cases, the library produced
`code span.` with no class for the NormalTok style (Michał Miszczyszyn).
Now it produces a rule for `code span`.
## 0.8.3.3
* Agda keywords updated to 2.6.0 (Andreas Abel).
## 0.8.3.2 -- 2020-01-21
* This fixes a packaging error in 0.8.3.1, which didn't include
the results of the bootsrap step and hence didn't update the
syntax modules.
## 0.8.3.1 -- 2020-01-21
* Escape `<` and `>` in latex to avoid ligatures (#91).
* Fix and extend Idris keywords (Denis Buzdalov).
* Update XML syntax definitions for javascript-react, qml,
typescript, javascript, cmake, cofee, latex, perl, python,
rest.
* Fixed bug with context shifts using `##` syntax for foreign context.
Previously we only handled these in IncludeRules, but
starting with the current batches of xml files they can occur
elsewhere too.
## 0.8.3 -- 2019-11-26
* Update XML syntax definitions for c, cmake, coffee, cpp, css,
diff, djangotemplate, elixir, elm, glsl, haskell, html, isocpp,
javascript-react, javascript, json, jsp, julia, latex, lua,
markdown, matlab, mediawiki, modelines, mustache, perl, php,
powershell, qml, rest, rust, typescript, vhdl.
* Fix highlighting errors with non-ASCII characters in JSON (#90).
This error was due to an optimization that made some incorrect
assumptions.
## 0.8.2.3 -- 2019-10-03
* Tests: ensure we read test files as UTF-8.
* Fix compiler warnings around Monoid imports.
* Add MonadFail constraint (allowing compilation with ghc 8.8.x).
* Add cabal.project and move CI from Travis to GitHub Actions.
## 0.8.2.2 -- 2019-09-30
* Remove upper bound on regex-base and require
regex-pcre-builtin >= 0.95, to avoid a build conflict
with earlier versions of regex-pcre-builtin and
regex-base >= 0.94.
* Remove unused system-pcre flag in skylighting.cabal.
This flag only affects skylighting-core.
## 0.8.2.1 -- 2019-09-25
* Add upper bound for regex-base if regex-pcre-builtin is used.
Currently regex-pcre-builtin won't build on ghc 8.4+ with
regex-base 0.94.0.0. When regex-pcre-builtin is updated, we
can remove this.
* Correct cabal wildcard to include .xml.patch files in distribution.
* Update breezedark style (Kien Dang).
* Update markdown.xml so first list marker is included in list (#84).
* skylighting.cabal - removed some build dependencies
which are not necessary (they're dependencies of skylighting-core).
## 0.8.2 -- 2019-07-14
* Change matchRegex so it gives "no match" on a regex error
instead of raising an exception. This seems to be how Kate
works. Fixes an error on long integer literals (#81).
## 0.8.1.2 -- 2019-07-14
* Fix HlCChar for one-character octal escapes like '\0' (#82).
Due to a bug in pCStringChar, only multi-character octal
escapes were being recognized. This affects not just C
highlighting, but all of the following highlighters which
use HlCChar: fasm eiffel pike objectivec ruby vhdl scala
java jsp nasm protobuf pure go objectivecpp gnuassembler povray
actionscript c cs opencl boo rhtml elixir. This fixes a
regression introduced in version 0.3.1.
* Ensure line span css only applied to lines (David Baynard).
## 0.8.1.1 -- 2019-06-13
* Improved LaTeX escaping (#78).
## 0.8.1 -- 2019-06-04
* Added support for stata (#74).
* Added support for javascript-react, i.e. jsx (#56).
* Added support for qml and mustache (new dependencies for
markdown and html).
* Update xml syntax definitions from KDE repository:
cmake, doxygen, html, ini, javascript, julia, literate-haskell,
markdown, octave, perl, tcsh, typescript, yaml.
* Fix bug in detectIdentifier (#76). It behaved wrongly when
applied to a string that was an valid identifier but had nothing
else after it (as would naturally occur with inline code in pandoc).
The bug caused it to match just one character in this case.
* Add --number-lines-from option to cli program (David Baynard).
* Override start number if nonzero (David Baynard, fixes regression
in 0.8).
## 0.8 -- 2019-05-27
* Wrap html source lines with `<span>`, not `<a>` (David
Baynard). Fixes jgm/pandoc#4386. Also fixes #33 (and
therefore fixes jgm/pandoc#4278).
* Prevent line-wrap overlap in html by increasing padding
(David Baynard).
* Remove superfluous 'pointer-events: all' (David Baynard).
* Simplify HTML generation code (David Baynard).
* Remove sourceLine class from spans (David Baynard).
* Display line numbers using css counters (David Baynard).
* Add Elm syntax definition (#66, #68, Bonghyun Kim).
* Put changelog in base directory, use symlinks to point to it.
We have the same changelog for skylighting and skylighting-core,
for simplicity. (Version numbers are kept in sync.)
## 0.7.7 -- 2019-02-27
* Add parseSyntaxDefinitionFromString [API change].
* Fix parseSyntaxDefinition so that language.dtd no longer needed.
We strip out the SYSTEM "language.dtd" part of the doctype
if present, leaving any inline entity definitions.
This applies to both parseSyntaxDefinition and
parseSyntaxDefinitionFromString.
* Revised documentation of bootstrap build.
* Makefile - fix bootstrap target.
* Use FilePath instead of String for path (#64, anchpop).
## 0.7.6 -- 2019-02-08
* Update xml definitions for C, CPP, D, Haskell, Maxima, PHP,
Ruby, Typescript.
* Fix regex problem in erlang.xml (#63).
* Export WordSet constructors (#62, Chris Martin).
* Add support for protobuf (#60).
## 0.7.5 -- 2018-12-01
* Updated definitions for cmake, lua, prolog, rust, yacc,
javascript.
* Added definition for sml (#53).
* Added definition for J (#50).
* Added definition for typescript (#57).
* Fix comments preceded by multiple spaces in bash.xml (#54).
* Add *.txt extension and text/plain mime type to default.xml
(#48).
* Add file:/// if we have a Windows path with a drive.
Otherwise HXT will take it to be a URI. See jgm/pandoc#4836.
## 0.7.4 -- 2018-10-08
* HTML output: use title instead of data-line-number.
data- attributes are not valid HTML 4, and we would like this to
work with HTML 4 (e.g. in epub v2). See jgm/pandoc#4920.
* Print FALLTHROUGH in --trace output.
* Updated syntax definitions for actionscript, awk, bash, c, clojure, cmake,
coffee, cs, css, dockerfile, email, fortran, gcc, haskell, ini, isocpp,
java, javadoc, javascript, jsp, kotlin, latex, lua, mediawiki, modelines,
modula-2, objectivec, objectivecpp, opencl, perl, powershell, prolog,
python, r, rest, rhtml, ruby, rust, scala, sql-mysql, sql-postgresql, sql,
tcl, vhdl, xml, xul, yaml, zsh.
## 0.7.3 -- 2018-08-27
* Add 'default.xml' to syntax descriptions.
* Raise base lower bounds to 4.8. Drop support for ghc 7.8.
* Use absolute number for cabal version, as now required.
## 0.7.2 -- 2018-06-08
* Update syntax definitions from upstream.
* Added support for POV-Ray syntax (#46).
* Display line numbers without absolute positioning (David
Baynard, #32).
## 0.7.1 -- 2018-03-15
* Fix benchmarks, which previously depended on a module
defined in skylighting (#42).
* Export Skylighting.Loader from Skylighting.Core.
* Bump version bound for criterion.
## 0.7.0.2 -- 2018-03-06
* Ensure that regex captures are not overwritten by regexes
without captures.
* Fixed bug in subDynamic (#41).
* Added tracing information about rules tried and dynamic
regexes, for debugging.
* Fix highlighting for Haskell chars which breaks `-XDataKinds` (#40,
Artyom Kazak).
## 0.7.0.1 -- 2018-03-03
* Updated changelog.md.
## 0.7 -- 2018-03-03
* Split skylighting into skylighting-core (BSD3) and skylighting (GPL)
(#37, Jonathan Daugherty). skylighting-core (BSD3 licensed) includes
the core library functionality and the source of the XML syntax, but
not the compiled Syntax modules, and skylighting (GPL2 licensed)
includes Syntax modules compiled from the XML syntax files.
* We discontinue support for GHC before 7.10 (because we need to support the
reexport-modules Cabal directive.)
* Print message about loaded syntax defs to stderr (#36).
* New module Skylighting.Loader, exporting
`loadSyntaxFromFile` and `loadSyntaxesFromDir` (Jonathan Daugherty).
* Adjust tests to load xml definitions dynamically.
## 0.6 -- 2018-01-18
* Add ANSI color output (Alexander Ronald Altman, #22).
+ New package dependencies: `ansi-terminal` and `colour`.
+ New module: `Skylighting.Format.ANSI`, exporting `formatANSI`,
(also reexported from the module `Skylighting`).
+ In `Skylighting.Types`, new types `ANSIColorLevel` and
`Xterm256ColorCode`, and a new field `ansiColorLevel` in
`FormatOptions`.
+ Main `skylighting` executable now supports ANSI output (use
`ansi` as argument to `--format`), which is now the default output
format. A new flag `--color-level` has been added to select
the number of colors (with options `16`, `256`, `true`, and
the default `auto`).
* Reword error for missing contexts in IncludeRules.
* Use ordNub instead of nub for missingIncludes.
## 0.5.1 -- 2018-01-07
* Fixed tokenizer exceptions (#31). Previously `throwError`
did not actually generate `Left` results in `tokenize`,
because of the way the MonadPlus instance worked. Rewrote
the TokenizerM monad from scratch so that exceptions would
not be skipped.
* Improved error message about undefined contexts.
* Makefile: use cabal for bootstrap target.
* README: remove stack bootstrap instructions.
You can no longer bootstrap with stack, because it
insists on building ALL the executables the first time,
and of course that can't be done with this library.
* Use quickcheck for fuzz test.
## 0.5.0.1 -- 2017-12-18
* Small improvements to fuzz tests in test suite. We now
ensure that we print the random text on test failure. Also,
we now run the test with many smaller samples rather than
one big one.
* Add aeson lower bound (because of toEncoding) (#28).
## 0.5 -- 2017-12-10
* Fix line spacing and overflowing content in generated HTML
(David Baynard, #25, see jgm/pandoc#4128).
+ Fix empty line height, explicitly
+ Ensure long lines scroll on screen
+ Only apply colour to the outer div
+ Don't reset line number colour
+ Fix borders on empty code lines
+ Collapse divs correctly.
* Changes to Style types and JSON instances. Previously we could not
successfully round-trip through JSON.
+ `tokenStyles` is now a map rather than an association list.
+ We now use `line-number-color` instead of `line-numbers` at
the top level in the JSON instances, falling back to
`line-numbers` in `editor-colors`, for KDE theme compatibility.
+ We use `line-number-background-color` at the top level, falling
back to the text background color.
+ We use `text-color` at the top level, falling back to the `text-color`
of the `Normal` token style if it exists, for KDE compatibility.
+ We use `background-color` at the top level, falling back to
the `background-color` in `editor-colors`, for KDE compatibility.
+ A round-trip JSON test has been added.
## 0.4.4.1 -- 2017-11-27
* HTML formatting: fix color, bgcolor when numbering enabled.
Previously, the code got the color and background color
the numbers were supposed to get. See jgm/pandoc #4103.
* Updated syntax descriptions for bash, clojure, commonlisp, diff,
dockerfile, doxygen, doxygenlua, fsharp, hamlet, haskell, haxe,
java, javascript, julia, latex, literate-curry, literate-haskell,
makefile, mediawiki, monobasic, ocaml, prolog, r, relaxng, scala,
sci, sql-mysql, sql-postgresql, sql, xslt.
* test program: use --accept instead of --regen.
## 0.4.4 -- 2017-11-21
* HTML formatter: always use an a element (rather than a div)
for source lines. The divs were invalid, because code
elements must contain phrasing content. Previously we used
a elements when line anchors were called for, but there is
no clear reason not to use them always.
* skylighting binary: add doctype to generated HTML.
## 0.4.3.2 -- 2017-11-04
* Fixed regression in `data-line-number` attributes in HTML
output. We should not include the `lineIdPrefix` in
front of this.
## 0.4.3.1 -- 2017-11-03
* Fixed typo in css (Artymort).
* Fixed travis build times.
## 0.4.3 --- 2017-11-02
* `FormatOptions`: added `lineIdPrefix` (jgm/pandoc#4031).
This is needed because a web page may contain several
code samples, and we need to make sure that the ids on
lines are unique.
* HTML formatter: use `lineIdPrefix` in ids for lines.
* HTML formatter: Don't put href attributes on divs.
## 0.4.2 --- 2017-10-26
* HTML output: remove outer div. This prevented margin
collapsing between the pre and surrounding block elements,
and often gave us excess white space around code blocks.
See jgm/pandoc#3996.
## 0.4.1 --- 2017-09-28
* Updated XML definitions from KDE repository.
Changed: actionscript, ada, agda, alert, alert_indent, asn1, awk, bash,
boo, c, changelog, clojure, cmake, coldfusion, commonlisp, cpp, cs, css,
curry, d, dockerfile, dot, doxygen, doxygenlua, eiffel, email, erlang,
fortran, fsharp, gcc, haskell, haxe, isocpp, java, javascript, jsp, julia,
lilypond, lua, m4, makefile, matlab, maxima, mips, modelines, modula-2,
monobasic, objectivec, objectivecpp, ocaml, octave, opencl, pascal, perl,
php, pike, postscript, prolog, purebasic, python, r, relaxng,
relaxngcompact, rest, rhtml, ruby, rust, scala, scheme, sci, sql-mysql,
sql-postgresql, sql, tcl, tcsh, verilog, vhdl, xml, xslt, xul, zsh.
* Added support for powershell, using definition from KDE repository.
* Stop terminating long builds on TravisCI (Kyle Ondy).
## 0.4 --- 2017-09-15
* Removed ToJSON/FromJSON instances for KeywordAttr,
WordSet, Matcher, Context, ContextSwitch, Rule, Syntax
(added in 0.3.5). Creating these increased the memory
requirements for compiling skylighting to a degree not
justified by the usefulness of these instances.
## 0.3.5 --- 2017-09-14
* Added ToJSON/FromJSON instances for all basic types.
* Added some background colors to 'kate' style, matching default.theme,
and made FromJSON for Style sensitive to background-color.
## 0.3.4.1 -- 2017-09-09
* HTML formatting: do not use `div` elements for source
lines in inline output.
## 0.3.4 -- 2017-09-09
* HTML formatting changes (David Baynard). Note that these
changes may require changes in hard-coded CSS that is
used with skylighting's HTML output.
+ Wrap lines of source code in a `div` with `display` set to
`inline-block`. The `div`s make per-line processing easier.
They cannot be set as `display: block` as that introduces extra
new lines when copying and pasting.
+ Render line numbers in html using CSS pseudo elements rather than
a table. The line numbers are always produced, as `data-line-number`
attributes, and css to display them as `::before` elements are
always produced. The option to switch on line numbering only
toggles a class; this means it is possible to toggle line numbering
without re-running skylighting.
+ If the `linkAnchors` option is set, wrap with an `a` element rather
than a `div`, set so that clicking the line number (and only the
line number) will jump to that line.
+ Code wraps by default when html is printed, with wrapped lines
indented.
## 0.3.3.1 -- 2017-06-26
* Updated xml syntax definitions and clojure test.
* Improved 'make update-xml' target.
* Updated version bound for criterion.
## 0.3.3 -- 2017-04-22
* Revert change from 0.3.2; now entities from a DTD are
resolved if the DTD element is included. This is needed
for agda.xml and some others. If you want to use a custom
xml definition without needing language.dtd, just remove
the reference to language.dtd in your xml file.
* Added `case` keyword for ats (Hanwen (Steinway) Wu).
## 0.3.2 -- 2017-04-01
* Parse xml definitions without resolving entities from
language.dtd. This allows xml definitions to be used even
when language.dtd isn't available. Existing definitions
don't rely on the two or three entities definied in
language.dtd, so this is harmless.
* Small optimizations.
## 0.3.1 -- 2017-02-28
* Use handwritten parser for Float instead of regex. Fixes
jgm/highlighting-kate#57 (again).
* Added float parsing tests.
* Use parsec parsers, not regex, for CStringChar and CChar.
* Rewrote Int, Hex, Oct, CStringChar, CCHar parsers with parsec
instead of regex. This speeds things up.
* Don't include leading + in Int, Hex, Oct parsers. That gives
bad results for things like `i+1`.
## 0.3 -- 2017-02-19
* Store literal binary-encoded representations of the Syntax
structure in Skylighting.Syntax.*.hs, instead of the
structure itself. This works around a problem ghc has
compiling modules with large structures. This indirect method
produces faster compile times and avoids massive memory usage by
ghc (especially in profiling builds). For background see
http://stackoverflow.com/questions/16348340/. Closes #7.
* Types: Internals of 'WordSet' are no longer exposed.
## 0.2 -- 2017-02-19
* Restore Data, Typeable, Generic instances for basic types.
To do this, we remove reCompiled field from RE (API change). Instead, we
have the tokenizer compile regexes the first time it encounters them,
memoizing the results. Performance is not significantly worse.
* Skylighting.Syntax.*: use string representation of the Syntax,
which is then 'read', rather than including the code for the data
structure directly (#7). This indirect method produces faster compile
times and avoids massive memory usage by ghc (especially in profiling
builds). For background see
http://stackoverflow.com/questions/16348340/compiling-very-large-constants-with-ghc
* Use -fprof-auto-exported for profiling builds.
* Added benchmark for xml syntax definition parsing.
* Patched perl.xml (improperly escaped regex) (#8).
This fixes a perl regex compilation error for regex patterns
with backslash as delimiter, e.g. m\a\.
* Add a flag to build with system pcre (Felix Yan).
## 0.1.1.5 -- 2017-02-03
* Avoid depending on a PrintfArg instance for Text (#5).
This isn't provided in some older versions of the text library.
This change should allow the package to build on older platforms.
## 0.1.1.4 -- 2017-01-31
* Properly escape characters in subDynamic.
This fixes a problem that caused failures with
echo -e "s\0b\0c" | skylighting -s perl
* More efficient rewrite of char escaping for regexes.
## 0.1.1.3 -- 2017-01-29
* Increase test timeout to 6s.
* Avoid double {{}} in latex macros.
* Fixed problem compiling Format.LaTeX on older ghc versions (7.8.3)
that can't take a Text as PrintfArg.
## 0.1.1.2 -- 2017-01-28
* Added much more extensive testing to ensure that tokenizers
don't hang or drop input.
* Fixed some issues with line-end and fallthrough context
handling.
* Fixed a bug in WordDetect handling which caused it to drop
input (#2).
## 0.1.1.1 -- 2017-01-21
* Optimized. Speed is now comparable to highlighting-kate
and often better.
* Added benchmarks.
## 0.1.1 -- 2017-01-19
* Added breezeDark style, from breeze-dark.theme.
* Fixed performance bug in regex application (#1). This gives a
significant speedup, especially for inputs with long lines.
## 0.1.0.1 -- 2016-12-23
* Fixed bug in LaTeX renderer (backslash in wrong position).
## 0.1.0.0 -- 2016-12-23
* Initial release
