Paragraphs are enclosed by `\bpar` and `\epar` commands, and `highlight`
commands are used for emphasis. This results in much better tagging in
PDF output.
Thanks and credit go to Aner Lucero, who laid the groundwork for this
feature in the 2021 GSoC project. He contributed many changes, including
modifications to the readers for HTML, JATS, and LaTeX, and to the HTML
and JATS writers.
Shared (Albert Krewinkel):
- The new function `figureDiv`, exported from `Text.Pandoc.Shared`,
offers a standardized way to convert a figure into a Div element.
Readers (Aner Lucero):
- HTML reader: `<figure>` elements are parsed as figures, with the
caption taken from the respective `<figcaption>` elements.
- JATS reader: The `<fig>` and `<caption>` elements are parsed into
figure elements, even if the contents is more complex.
- LaTeX reader: support for figures with non-image contents and for
subfigures.
- Markdown reader: paragraphs containing just an image are treated as
figures if the `implicit_figures` extension is enabled. The identifier
is used as the figure's identifier and the image description is also
used as figure caption; all other attributes are treated as belonging
to the image.
Writers (Aner Lucero, Albert Krewinkel):
- DokuWiki, Haddock, Jira, Man, MediaWiki, Ms, Muse, PPTX, RTF, TEI,
ZimWiki writers: Figures are rendered like Div elements.
- Asciidoc writer: The figure contents is unwrapped; each image in the
the figure becomes a separate figure.
- Classic custom writers: Figures are passed to the global function
`Figure(caption, contents, attr)`, where `caption` and `contents` are
strings and `attr` is a table of key-value pairs.
- ConTeXt writer: Figures are wrapped in a "placefigure" environment
with `\startplacefigure`/`\endplacefigure`, adding the features
caption and listing title as properties. Subfigures are place in a
single row with the `\startfloatcombination` environment.
- DocBook writer: Uses `mediaobject` elements, unless the figure contains
subfigures or tables, in which case the figure content is unwrapped.
- Docx writer: figures with multiple content blocks are rendered as
tables with style `FigureTable`; like before, single-image figures are
still output as paragraphs with style `Figure` or `Captioned Figure`,
depending on whether a caption is attached.
- DokuWiki writer: Caption and "alt-text" are no longer combined. The
alt text of a figure will now be lost in the conversion.
- FB2 writer: The figure caption is added as alt text to the images in
the figure; pre-existing alt texts are kept.
- ICML writer: Only single-image figures are supported. The contents of
figures with additional elements gets unwrapped.
- HTML writer: the alt text is no longer constructed from the caption,
as was the case with implicit figures. This reduces duplication, but
comes at the risk of images that are missing alt texts. Authors should
take care to provide alt texts for all images.
Some readers, most notably the Markdown reader with the
`implicit_figures` extension, add a caption that's identical to the
image description. The writer checks for this and adds an
`aria-hidden` attribute to the `<figcaption>` element in that case.
- JATS writer: The `<fig>` and `<caption>` elements are used write
figures.
- LaTeX writer: complex figures, e.g. with non-image contents and
subfigures, are supported. The `subfigure` template variable is set if
the document contains subfigures, triggering the conditional loading
of the *subcaption* package. Contants of figures that contain tables
are become unwrapped, as longtable environments are not allowed within
figures.
- Markdown writer: figures are output as implicit figures if possible,
via HTML if the `raw_html` extension is enabled, and as Div elements
otherwise.
- OpenDocument writer: A separate paragraph is generated for each block
element in a figure, each with style `FigureWithCaption`. Behavior for
single-image figures therefore remains unchanged.
- Org writer: Only the first element in a figure is given a caption;
additional block elements in the figure are appended without any
caption being added.
- RST writer: Single-image figures are supported as before; the contents
of more complex images become nested in a container of type `float`.
- Texinfo writer: Figures are rendered as float with type `figure`.
- Textile writer: Figures are rendered with the help of HTML elements.
- XWiki: Figures are placed in a group.

This is to prevent Lucida Console from being used on Windows, where
there seems to be a spacing issue in some applications, with boldface
glyphs wider than regular ones.
Closes#8543.
when `mainlang` and a lang are specified and pdflatex is not being used.
This is needed for good results in Arabic and doesn't seem to hurt
for other languages we've tried.
Closes#8538.
- Add module Text.Pandoc.Writers.ChunkedHTML,
exporting writeChunkedHtml [API change].
- Revised API for Text.Pandoc.Chunks.
`chunkNext`, `chunkPrev`, `chunkUp` are now
just `Maybe Chunk`.
- Fix assignment of navigation elements of Chunks.
- Strip off anchor portion of next and prev links.
- Remove Ord instances for SecInfo, Chunk.
- Derive Show, Eq, Generic for ChunkDoc.
- Add `chunkSectionNumber`, `chunkUnlisted`.
- Automatically unwrap the zip to a directory
if an extensionless output file specified.
- Incorporate images with relative paths below working dir.
...and font family in default inline css. Closes#8423
(see comments there for motivation). `mainfont`, `fontsize`,
and `linestretch` can still be used as before; the only difference
is that we no longer provide opinionated defaults.
This commit also adds a `maxwidth` variable that sets `max-width`;
if not set, 36em is used as a default.
With this change, we reduce the amount of inline CSS used
for EPUBs. Almost everything is now in the default EPUB
CSS (`data/epub.css`), which can be overridden either by
putting `epub.css` in the user data directory or by using
`--css` on the command line. Inline styles are only used
for syntax highlighting (which depends on the style specified,
and is only included on pages with highlighted code) and
for bibliography formatting (which can depend on the CSL
style, and is only used in the page containing the bibliography).
Note that, for compatibility with older readers, we don't
use flexbox to style `column/columns` divs by default, as
we do in HTML. Instead, we use an older method which only
works when there are two `column` divs inside a `columns`
div. If you need more than two columns and aren't worried
about support for older EPUB readers, you can modify the
default CSS (there is a comment in the CSS telling you what to do).
Closes#8379.
Beamer themes such as metropolis and saintpetersburg change the default
fonts. This change gives precedence to the user font settings by moving
them after the loading of the Beamer theme.
The `T.P.Lua.writeCustom` function changed to allow either a TextWriter
or ByteStringWriter to be returned. The global variables
`PANDOC_DOCUMENT` and `PANDOC_WRITER_OPTIONS` are no longer set when the
writer script is loaded. Both variables are still set in classic writers
before the conversion is started, so they can be used when they are
wrapped in functions.
The default `flex` and `overflow-x` properties of a column are set to
`auto`. In combination, these changes allow to get good results when
using columns with or without explicit widths.
Fixes a regression that required the `boxlinks` variable to be set in
addition to the usual link coloring variables. Otherwise links were
never colored in LaTeX PDF output.
Fixes: #8226
This ensures that there is a space between the checkbox
and the following content and that subsequent content lines up.
Closes#8151.
Supersedes and closes#8163.
Using the default jats template of pandoc 2.18, the https://jats4r.org/jats4r-validator/ warns: "The license URI is given in `@xlink:href`. For JATS 1.1d3 and later, if the license is defined by a canonical URI, then it should be specified in the `<ali:license_ref>` child element."
I can confirm that what JATS4R recommends here is consistent with the JATS article packages found on the FTP site for the
PubMed Central Open Access Subset <https://www.ncbi.nlm.nih.gov/pmc/tools/openftlist/> (at least with the eLife article I looked at).
This proposed change follows the JATS4R recommendation and an example eLife article on the PubMed Central FTP site.
The following table feature are now supported in ConTeXt:
- colspans,
- rowspans,
- multiple bodies,
- row headers, and
- multi-row table head and foot.
The wrapping `placetable` environment is also given a `reference` option
with the table identifier, enabling referencing of the table from within
the document.
The document hierarchy is now conveyed using the
`\startsectionlevel`/`\stopsectionlevel` by default. This makes it easy
to include pandoc-generated snippets in documents at arbitrary levels.
The more semantic environments "chapter", "section", "subsection", etc.
are used if the `--top-level-division` command line parameter is set to
a non-default value.
Closes: #5539
This used to be necessary to avoid problems with hyperref,
when headings contain strikeout text, but it does not seem to be
necessary any more (tested).
