include `header`. This change causes pandoc to omit the middle
header parameter when `header` is not set, rather than
emitting `""`. The parameter is optional and man will use
a default based on the section if it is not specified.
Closes#9943.
New cli option: `--link-images`. This causes images to be linked
rather than embedded in ODT.
New field in WriterOptions: `writerLinkImages` [API change].
New field in Opt: `optLinkImages` [API change].
Closes#9815.
The modules `lpeg` and `re` are now treated as if they had been
loaded with `require`. Previously the modules were only assigned
to global values, but could be loaded again via `require`,
thereby allowing to use a system-wide installation. However, this
proved to be confusing.
The old behavior can be restored by adding the following lines to
the top of Lua scripts, or to the `init.lua` in the data dir.
debug.registry()['_LOADED'].lpeg = nil
debug.registry()['_LOADED'].re = nil
The Lua interpreter no longer terminates when called with `-v` or
`--version` arguments, thus improving compatibility with the default
`lua` interpreter program.
This was added in a period when MathJaX required polyfill.
MathJaX no longer recommends this and polyfill should no
longer be necessary on any reasonably modern browser.
Closes#9918.
Previously we relied on graphicx internals and made global
changes to Gin to force images to be resized if they exceed
textwidth. This approach is brittle and caused problems
with `\includesvg` (see #9660).
The new approach uses a new macro `\pandocbounded` that is
now defined in the LaTeX template. (Thanks here to Falk Hanisch in
https://github.com/mrpiggi/svg/issues/60.)
The LaTeX writer has been changed to enclose `\includegraphics`
and `\includesvg` commands in this macro when they don't explicitly
specify a width or height.
In addition, the writer now adds `keepaspectratio` to the
`\includegraphics` or `\includesvg` options if `height` is specified
without width, or vice versa. Previously, this was set in the preamble
as a global option.
Compatibility issues:
- If custom templates are used with the new LaTeX writer, they will have
to be updated to include the new `\pandocbounded` macro, or an error
will be raised because of the undefined macro.
- Documents that specify explicit dimensions for an image may render
differently, if the dimensions are greater than the line width or
page height. Previously pandoc would shrink these images to fit,
but the new behavior takes the specified dimensions literally.
In addition, pandoc previously always enforced `keepaspectratio`,
even when width and height were both specified, so images with
width and height specified that do not conform to their intrinsic
aspect ratio will appear differently.
Closes#9660.
In some cases we need to break up a long text run including
both western and East Asian text, so that the punctuation in
the western text doesn't become double-wide.
Closes#9817.
It is supposed to replace emojis with their aliases,
but previously this only worked when the emojis were
in a specially marked span.
Note that this change doesn't affect `commonmark` (or `gfm`)
because the relevant code is in commonmark-hs. This will also
need updating.
See #9876.
- Turn captioned images into Figure elements. Closes#9391.
- Improve the logic for associating elements with captions.
Closes#9358.
- Ensure that captions that can't be associated with an
element aren't just silently dropped. Closes#9610.
