beamer uses pdfstring for the pdfinfo which can't handle soul strikeouts.
Therefore, the title, subtitle and author contents need to be put inside
texorpdfstring to deal with both the pdfinfo as well as the formatting.
Fixes#11168.
This reverts commit 3f1f58e96e.
The reason for reverting this change is that it led to an
undesirable behavior change. Documents with no explicit date
specified now have a date printed, because the default
title block will include a date if no `\date` command is used.
The empty `\date{}`, by contrast, suppressed the date, which
is the desirable behavior.
PR #10687 was motivated by the desire to include a custom `\date`
in the frontmatter via header-includes. I think that aim can
be achieved more simply by simply setting the `date` variable.
In markdown you can even use `date:` in metadata and put some
raw LaTeX there.
This allows one, for example, to set a custom \date in the
header-includes of the rmarkdown yaml frontmatter. Without this
conditional, the custom \date in the frontmatter would be overridden by
a (potentially empty) date from this template later.
- Split fonts.latex partial into two parts: fonts.latex and
font-settings.latex.
- In beamer template, load beamer theme between fonts.latex and
font-settings.latex. This allows a theme (such as metropolis)
to set its own default font, while still allowing the user to
override it.
This fixes a regression in pandoc 3.5.
Users who have custom templates based on pandoc 3.5 templates will
need to add `font-settings.latex()` after `fonts.latex()` in the
latex template. In a beamer template, the beamer theme-setting
code needs to be moved between these two partials.
Closes#10297.
+ Add `shorttitle`, `shortsubtitle`, `shortauthor`, `shortinstitute`, `shortdate`
to default.beamer.
+ Note that the brackets are inside conditionals, because some older beamer
versions don't allow the empty optional argument.
Closes#10248.
+ Remove section numbering code from common.latex
+ Add section numbering to default.latex
+ Add logic for numbering sections in default.beamer. I moved the template setting
code to where other beamer templates are set. This makes the section-titles and
numbersections variables independent.
This should make --number-sections work with beamer.
+ Split out common parts of latex template into partials: common.latex,
fonts.latex, font-settings.latex, passoptions.latex, hypersetup.latex,
after-header-includes.latex.
+ Split out old latex template into default.latex and default.beamer.
+ Make default.beamer the default template for beamer.
We now use the default.latex template for both latex and beamer.
It contains conditionals for the beamer-specific things.
`pandoc -D beamer` will return this template.
Previously the LaTeX writer created invalid LaTeX
when `--listings` was specified and a code span occured
inside emphasis or another construction.
This is because the characters `%{}\` must be escaped
in lstinline when the listinline occurs in another
command, otherwise they must not be escaped.
To deal with this, adoping Michael Kofler's suggestion,
we always wrap lstinline in a dummy command `\passthrough`,
now defined in the default template if `--listings` is
specified. This way we can consistently escape the
special characters.
Closes#1629.
