[API change]
* Depend on ipynb library.
* Add `ipynb` as input and output format.
* Added Text.Pandoc.Readers.Ipynb (supports both nbformat v3 and v4).
* Added Text.Pandoc.Writers.Ipynb (supports nbformat v4).
* Added ipynb readers and writers to T.P.Readers,
T.P.Writers, and T.P.Extensions. Register the
file extension .ipynb for this format.
* Add `PandocIpynbDecodingError` constructor to Text.Pandoc.Error.Error.
* Note: there is no template for ipynb.
Use the [`footnotehyper`](https://ctan.org/pkg/footnotehyper/) package if available.
This is a rewrite of `footnote` that is compatible with `hyperref` and `babel-frenchb`.
This patch also addresses the incompatibility with `xcolor` noted in #4861, but the
new package has only been available since 2016, so this template still loads `xcolor`
earlier for compatibility with older distributions. Note that the `footnote` package
is part of `collection-latexrecommended` in TeX Live, so there shouldn't be any
problem loading it unconditionally as we now do if `footnotehyper` is not available.
Ensure that `\part` and `\chapter` are only numbered if `numbersections` is set. To return to the previous behaviour, use `-V numbersections -V secnumdepth=0`.
Notes on secnumdepth:
1 = Number `\section`
0 = Number `\chapter`
-1 = Number `\part`
-2 = No numbering
Previously the `.0` was interpreted as a file extension,
leading pandoc not to add `.tex` (and thus not to find the
file).
The new behavior matches tex more closely.
Incorrect types to pandoc element constructors are automatically
converted to the correct types when possible. This was already done for
most constructors, but conversions are now also done for nested
types (like lists of lists).
Simplify the approach of #5212, ensuring that `mainfont` is used as the base font for scaling and that LuaLaTeX does not display the mono font with TeX ligatures (as it does not use the `Mapping=tex-ansi` option).
With a modified version of `\defaultfontfeatures`, fontspec will continue to report scaling against the old default font in the log, but it nonetheless displays main font at the specified size. Using this rather than setting `Scale=MatchLowercase` for each family individually means that users will not lose scaling when upgrading to the new template if they were using other font options. Scaling can be disabled for an individual family by adding the option `Scale=1` to `sansfontoptions`, `monofontoptions`, etc.
Remove the `\setromanfont` command added in #4665, as this is not documented in the fontspec manual and appears to be a deprecated alias for `\setmainfont`.
For the release notes, I should also add that one can imitate the previous appearance with `-V mainfontoptions="Scale=MatchLowercase"`.
Addresses closed issues #4675, #3896, #1327.
This renders `\subtitle` using the `etoolbox` package if `\subtitle` is not already
defined by the documentclass (as it is in beamer, KOMA, memoir classes).
Based on an example from Enrico Gregorio, <https://tex.stackexchange.com/a/50186>.
Update list of LaTeX packages.
Note that `etoolbox` must be loaded outside the command definition.
Putting it inside causes an error if `\title` is placed after `\begin{document}`.
It's already loaded on LuaLaTeX/XeLaTeX in any case.
When `Scale=MatchLowercase` is set as a default font option, this scales `mainfont` against the old default, meaning that it resizes whatever is set as the main font to match the metrics of Latin Modern. This can result, for example, in a document set to 12pt appearing in 11pt or 13pt. Setting this option for individual families allows everything to scale against the main font, and permits the user to override the setting if desired. Note that it is not necessary to specify `Ligatures=TeX`, as this is already set by default for the appropriate families. See the `fontspec` manual: <https://ctan.org/pkg/fontspec>.
Those who specify font-options in metadata may need to add `Scale=MatchLowercase`, which will now only be provided if `(roman|sans|math|mono)fontoptions` aren't given explicitly.
* These were added by the RST reader and, for literate Haskell,
by the Markdown and LaTeX readers. There is no point to
this class, and it is not applied consistently by all readers.
See #5047.
* Reverse order of `literate` and `haskell` classes on code blocks
when parsing literate Haskell. Better if `haskell` comes first.
* Ensure that we don't get > 2 levels of section nesting,
even with slide level > 2.
* If slide level == N but there is no N-level header, make
sure the next header with level > N gets treated as a slide
and put in a section, rather than remaining loose.
Closes#5168.
Underscore emphasis can't cross table cell boundaries,
but the parser wasn't respecting this, leading to exponential
behavior in documents with table cells containing underscores.
This fixes the original sample; it's possible that there
are other performance issues involving underscores.
Closes#3921.
* Use Babel for LuaTeX. There are a number of bugs in Polyglossia under LuaLaTeX with common languages, e.g. <https://github.com/reutenauer/polyglossia/issues/182>.
* Load xcolor. The `xcolor` package must be loaded before the `footnote` package, which we load to fix foonotes in tables. Closes#4861.
* Load xurl if available. This breaks URLs in more locations. Only available with TeX Live 2018 and later.
* Remove obsolete fixltx2e package
* Reindent. Use two spaces to be consistent internally and with other templates.
* Use `bookmark` if available. The `bookmark` package can sometimes correct the levels of headings where `hyperref` cannot: see <https://komascript.de/release3.26>.
* Update LaTeX tests
