Issue #1977
Most markdown processors support the [shortcut format] for reference links.
Pandoc's markdown reader parsed this shortcuts unoptionally.
Pandoc's markdown writer (with --reference-links option) never shortcutted links.
This commit adds an extension `shortcut_reference_links`. The extension is
enabled by default for those markdown flavors that support reading shortcut
reference links, namely:
- pandoc
- strict pandoc
- github flavoured
- PHPmarkdown
If extension is enabled, reader parses the shortcuts in the same way as
it preveously did. Otherwise it would parse them as normal text.
If extension is enabled, writer outputs shortcut reference links unless
doing so would cause problems (see test cases in `tests/Tests/Writers/Markdown.hs`).
The `tabular` environment allows non-empty column separators
with the "@{...}" syntax. Previously, pandoc would fail to
parse tables if a non-empty colsep was present. With this
commit, these separators are still ignored, but the table gets
parsed. A test case is included.
The `tabular` environment takes an optional parameter for
vertical alignment. Previously, pandoc would fail to parse
tables if this parameter was present. With this commit,
the parameter is still ignored, but the table gets
parsed. A test case is included.
GFM and PHP Markdown Extra pipe tables require headers.
Previously pandoc allowed pipe tables not to include headers,
and produced headerless pipe tables in Markdown output, but this
was based on a misconception about pipe table syntax. This
commit fixes this.
Note: If you have been using headerless pipe tables, this may
cause existing tables to break.
Closes#1996.
Previously these were always escaped and printed verbatim.
Now they are ignored unless the format is "icml", in which
case they are passed through unescaped.
Closes#1951.
The preferred syntax for Images and other media is [[File:Foo.jpg]] in MediaWiki since v1.14 (2008). [[Image:Foo.jpg]] is deprecated but still works as an alias to the File namespace.
This change improves output formatting of content with a large amount of force line breaks, such as line-blocks. The following writers are affected:
* Dokuwiki
* HTML
* EPUB (via HTML)
* LaTeX
* MediaWiki
* OpenDocument
* Texinfo
This commit resolves#1924
