# Changelog for commonmark-extensions
## 0.2.7
* Math extension: bail out on pathological nestings.
This means we can't handle TeX math with more than 1000 levels of
`{..}` nesting, but no real formula will go this far.
* Math extension: do not allow math closer followed by digit (#167,
Michael Howell). With this change, closing `$` cannot be
followed by a decimal digit. For example, `$1$` is fine, but
`$1$2` is not. This avoids some false positives like `Current
conversion rate makes US$99 about A$137`.
* Fix the blank line scanner after the `]` (Michael Howell).
* Fix disagreement with GitHub about block nesting in tasklists
(Michael Howell). Text on the same line as the task marker can't
start a block. It has to be paragraph text.
* Fix incorrectly computed indent on `task_list` (Michael Howell).
## 0.2.6
* Track wikilinks with a class instead of the title (Evan
Silberman). The use of title="wikilink" in HTML output traces
back to Pandoc's hijacking of the title attribute for this purpose
back when Pandoc links didn't have Attrs. A coordinated change in
Pandoc moves this more appropriately into a class.
## 0.2.5.6
* Autolink parser: track balanced brackets in path (improves
on #156). We still get a link within a link, which isn't right, but at
least the link goes to the right place. Cf. jgm/pandoc#10333.
## 0.2.5.5
* Fix auto_identifiers extension: it now replaces emojis with
their aliases, as documented.
* Fix auto_identifiers_ascii extension: it now ignores
non-ASCII characters with no ASCII equivalent.
## 0.2.5.4
* Fix autolink parsing regression (#151). This affects autolinks with
doubled internal line-ending punctuation characters.
## 0.2.5.3
* Fix rebase_relative_paths extension so it works with URLs with
non-ASCII characters (#148). Previously these would not be properly
detected as absolute URIs.
## 0.2.5.2
* Improve autolinks extension (#147).
The autolinks extension was interacting badly with explicit links,
To fix this we had to make autolink parsing a bit stricter than
the GFM spec does. They allow unbalanced `)` except at the end
of a URL (which is defined as: followed by optional final punctuation
then whitespace or eof). With this change, we don't allow unbalanced
`)` at all in raw URLs. This should not be a big problem in practice.
* Protect against quadratic generated table size explosion (Michael Howell).
This commit adds a limit to the number of auto-completed cells
around 200,000. The result is, in these original samples:
## 0.2.5.1
* Add `test/alerts.md` to extra-source-files in cabal file.
## 0.2.5
* Add support for alerts extension, supporting GitHub-style alerts (#132).
<https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#alerts>
New module Commonmark.Extensions.Alerts [API change].
* Do not accept footnote labels with line breaks (Michael Howell).
* Parse `[^ ]` and `[^]` as links (Michael Howell). This is consistent with
most other CommonMark parsers, even when they have support for footnotes turned on.
## 0.2.4
* Make `pipe_tables` extension treat backslash escapes like GH does (#112,
Michael Howell). This change essentially changes the way the text
`\\|` gets parsed inside a table. In the old version, the first backslash
escapes the second backslash, and then the pipe is treated as a cell
separator. In the new version, the pipe is still preceded by a backslash,
so it is still literal text. The escaping rule is documented in detail
in the spec for this extension. This change also aligns our escaping
of pipes with GitHub's.
## 0.2.3.6
* Fix pipe table parser so that `|`s don't interfere with
other block structures (Michael Howell, #111, fixing #52 and
#95). This parser is structured as a system that parses the
*second* line first, then parses the first line. That is, if
it detects a delimiter row as the second line of a
paragraph, it converts the paragraph into a table. This
seems counterintuitive, but it works better than trying to
convert a table into a paragraph, since it might need to be
something else.
* Improve parsing of inline math (#110).
## 0.2.3.5
- Resolve entities inside wikilinks (#105, Michał Kukieła).
## 0.2.3.4
- Require whitespace after definition list marker (#104).
Otherwise we can inadvertently clobber strikeout or subscript.
## 0.2.3.3
- Fix definition_lists extension (#96). We were not properly consuming
indentation in definitions, which caused problems when the definitions
themselves contained lists.
## 0.2.3.2
- Update lower version bounds for commonmark (#93, David
Thrane Christiansen).
## 0.2.3.1
- `math` extension: don't fail when display math contains
embedded inline math. See jgm/pandoc#7942.
- Make math parsing more sophisticated.
Count embeddings inside `{..}`, since math can contain
e.g. `\text{...}` which itself contains math delimiters.
- Small improvement in pipe table parsing.
The old parser failed on some edge cases with extra whitespace
after pipes (which we should just ignore).
- `fancy_list` extension: improve list type ambiguity resolution (#89).
## 0.2.3
- Allow bare word attribute in fenced_divs (#84). This follows a similar
change in pandoc (jgm/pandoc#7242).
## 0.2.2.1
- Fix commonmark-extensions to build with GHC 9.2 (#81, Joseph C. Sible).
Currently `--allow-newer` is needed.
## 0.2.2
- Add footnote to gfmExtensions. Note that this also requires
additional type constraints on gfmExtensions [API change].
## 0.2.1.2
- Fix bug with absolute paths in rebase_relative_paths
extension on Windows.
## 0.2.1.1
- Fix bug in wikilinks extensions.
## 0.2.1
- Add `rebase_relative_paths` extension.
New exported module Commonmark.Extensions.RebaseRelativePaths [API change].
- Add `wikilinks_title_before_pipe` and `wikilinks_title_after_pipe`
extensions (#69).
New exported module Commonmark.Extensions.Wikilinks [API change].
## 0.2.0.4
- Add a test for autolinks (#66).
- Require commonmark 0.1.1.2 (otherwise autolinks don't work
properly).
## 0.2.0.3
- Add some new test examples to the autolinks extension spec (#65).
- Allow interior `~` characters in autolinks (#65).
## 0.2.0.2
- Remove unnecessary Typeable constraint on `TaskList` and
`gfmExtensions` (#58).
- Fix bug in `footnote` extension: multiple blocks in
a block container (e.g. block quote or list) inside
a footnote were being rendered in reverse order (#63,
Harald Gliebe).
## 0.2.0.1
- Added a missing test file to extra-source-files (#55).
## 0.2.0.0
- Add HasQuoted class in Smart extension, with singleQuoted
and doubleQuoted methods. This gives more fleibility in
supporting smart quotes, and allows us to use pandoc's
Quoted elements.
- Add advice to haddocks for pipeTableSpec (#52).
If a line could be a candidate pipe table heading, but the
following line of separators is not encountered, the line is
treated as a paragraph, even if it has indications of other
block-level formatting. Putting the pipeTableSpec AFTER
parsers for lists, headings, etc. causes the latter to take
priority.
## 0.1.0.0
- Initial release
