2020-07-19Markdown writer: use unicode super/subscript characters...John MacFarlane1-18/+44
when possible if the superscript or subscript extension or raw_html aren't available.
2020-07-19Markdown writer: render caption as following paragraph...John MacFarlane1-2/+5
when `Ext_table_caption` not enabled.
2020-07-19Add commonmark_x output format...John MacFarlane4-3/+34
commonmark with a number of useful extensions (more than gfm).
2020-07-19Trim down githubMarkdownExtensions.John MacFarlane1-9/+11
Previously it included all of the following, which make sense for the legacy markdown_github but not for gfm, since they are part of base commonmark and thus can't be turned off in gfm: - `Ext_all_symbols_escapable` - `Ext_backtick_code_blocks` - `Ext_fenced_code_blocks` - `Ext_space_in_atx_header` - `Ext_intraword_underscores` - `Ext_lists_without_preceding_blankline` - `Ext_shortcut_reference_links` ` These have been removed from `githubMarkdownExtensions`, though they're still turned on for legacy `markdown_github`.
2020-07-19Add generic `attributes` extension.John MacFarlane2-8/+3
This allows attributes to be added to any block or inline element, in principle. (Though in many cases this will be done by adding a Div or Span container, since pandoc's AST doesn't have a slot for attributes for most elements.) Currently this is only possible with the commonmark and gfm readers. Add `Ext_attributes` constructor for `Extension` [API change].
2020-07-19Use commonmark-hs to parse commonmark/gfm...John MacFarlane2-198/+57
...instead of cmark-gfm (a wrapper around a C library). We can now support many more pandoc extensions for commonmark and gfm. Add fenced_code_attributes to gfm/commonmark extensions.

2020-07-18DocBook reader: parse releaseinfo as metadata.John MacFarlane1-0/+1
Closes #6542. Note that you'll need to put releaseinfo somewhere in your template if you want this to be part of the converted output.

2020-07-01HTML writer: improve alt-text/caption handling for HTML5Albert Krewinkel1-2/+10
Screen readers read an image's `alt` attribute and the figure caption, both of which come from the same source in pandoc. The figure caption is hidden from screen readers with the `aria-hidden` attribute. This improves accessibility. For HTML4, where `aria-hidden` is not allowed, pandoc still uses an empty `alt` attribute to avoid duplicate contents. Closes: #6491
2020-07-01Org reader: respect tables-excluding export settingAlbert Krewinkel3-2/+7
Tables can be removed from the final document with the `#+OPTION: |:nil` export setting.

Footnotes can be removed from the final document with the `#+OPTION: f:nil` export setting.
2020-06-30Ipnyb: allow lossless round-tripping of markdown cell content.John MacFarlane2-3/+7
The reader now parses the contents of the markdown cell to a Pandoc structure, but *also* stores the raw markdown in a `source` attribute on the cell Div. When we convert back to markdown, this attribute is stripped off and the original source is used. When we convert to other formats, the attribute is usually ignored (though it will come through in HTML as a `data-source` attribute, not unhelpfully). I'll note some potential drawbacks of this approach: - It makes it impossible to use pandoc to clean up or change the contents of markdown cells, e.g. going from `+smart` to `-smart`. - There may be formats where the addition of the `source` attribute is problematic. I can't think of any, though. Closes #5408.
2020-06-30Org reader: respect export setting which disables entitiesAlbert Krewinkel3-6/+16
MathML-like entities, e.g., `\alpha`, can be disabled with the `#+OPTION: e:nil` export setting.

Unify defaults metadata and markdown metadata parsers
2020-06-29Org reader: keep unknown keyword lines as raw orgAlbert Krewinkel2-2/+13
The lines of unknown keywords, like `#+SOMEWORD: value` are no longer read as metadata, but kept as raw `org` blocks. This ensures that more information is retained when round-tripping org-mode files; additionally, this change makes it possible to support non-standard org extensions via filters.
2020-06-29Org reader: unify keyword handlingAlbert Krewinkel1-75/+67
Handling of export settings and other keywords (like `#+LINK`) has been combined and unified.
2020-06-29Org reader: support LATEX_HEADER_EXTRA and HTML_HEAD_EXTRA settingsAlbert Krewinkel1-5/+9
These export settings are treated like their non-extra counterparts, i.e., the values are added to the `header-includes` metadata list.
2020-06-29Org reader: allow multiple #+SUBTITLE export settingsAlbert Krewinkel1-0/+1
The values of all lines are read as inlines and collected in the `subtitle` metadata field.

The value is stored in the `institute` metadata field and used in the default beamer presentation template.
2020-06-28Org reader: update behavior of author, keywords export settingsAlbert Krewinkel1-19/+9
The behavior of the `#+AUTHOR` and `#+KEYWORD` export settings has changed: Org now allows multiple such lines and adds a space between the contents of each line. Pandoc now always parses these settings as meta inlines; setting values are no longer treated as comma-separated lists. Note that a Lua filter can be used to restore the previous behavior.

2020-06-27Org reader: read description lines as inlinesAlbert Krewinkel1-10/+46
`#+DESCRIPTION` lines are treated as text with markup. If multiple such lines are given, then all lines are read and separated by soft linebreaks. Closes: #6485
2020-06-25Org reader: honor tex export optionAlbert Krewinkel4-30/+75
The `tex` export option can be set with `#+OPTION: tex:nil` and allows three settings: - `t` causes LaTeX fragments to be parsed as TeX or added as raw TeX, - `nil` removes all LaTeX fragments from the document, and - `verbatim` treats LaTeX as text. The default is `t`. Closes: #4070

This fixes #6481, allowing grid tables to be enclosed in fenced divs with no intervening blank lines.
