* New module: Text.Pandoc.Writers.Ms.
* New template: default.ms.
* The writer uses texmath's new eqn writer to convert math
to eqn format, so a ms file produced with this writer
should be processed with `groff -ms -e` if it contains
math.
All templates now include `code{white-space: pre-wrap}`
and CSS for `q` if `--html-q-tags` is used.
Previously some templates had `pre` and others `pre-wrap`;
the `q` styles were only sometimes included.
See #3485.
Polyglot markup is HTML5 that is also valid XHTML. See
<https://www.w3.org/TR/html-polyglot>. With this change, pandoc's
html5 writer creates HTML that is both valid HTML5 and valid XHTML.
See jgm/pandoc-templates#237 for prior discussion.
* Add xml namespace to `<html>` element.
* Make all `<meta>` elements self closing.
See <https://www.w3.org/TR/html-polyglot/#empty-elements>.
* Add `xml:lang` attribute on `<html>` element, defaulting to blank, and
always include `lang` attribute, even when blank. See
<https://www.w3.org/TR/html-polyglot/#language-attributes>.
* Update test files for template changes.
The key justification for having language values default to blank: it
turns out the HTML5 spec requires it (as I read it). Under
[the HTML5 spec, section "3.2.5.3. The lang and xml:lang
attributes"](https://www.w3.org/TR/html/dom.html#the-lang-and-xmllang-attributes),
providing attributes with blank contents both:
* Has meaning, "unknown", and
* Is a MUST (written as "must") if a language value is not provided ...
> The lang attribute (in no namespace) specifies the primary language
> for the element's contents and for any of the element's attributes that
> contain text. Its value must be a valid BCP 47 language tag, or the
> empty string. Setting the attribute to the empty string indicates that
> the primary language is unknown.
In short, it seems that where a language value is not provided then a
blank value MUST be provided for Polyglot Markup conformance, because
the HTML5 spec stipulates a "must". So although the Polyglot Markup spec
is unclear on this issue it would seem that if it was correctly written,
it would therefore require blank attributes.
Further justifications are found at
https://github.com/jgm/pandoc-templates/issues/237#issuecomment-275584181
(but the HTML5 spec justification given above would seem to be the
clincher).
In addition to having lang-values-default-to-blank I recommend that, when an
author does not provide a lang value, then upon on pandoc command execution
a warning message like the following be provided:
> Polyglot markup stipulates that 'The root element SHOULD always specify
> the language'. It is therefore recommended you specify a language value in
> your source document. See
> <https://www.w3.org/International/articles/language-tags/> for valid
> language values.
Removed writerDocbookVersion in WriterOptions.
Renamed default.docbook template to default.docbook4.
Allow docbook4 as an output format.
But alias docbook = docbook4.
This fixes hyperlinks on footnotes in documents that contain
verbatim in notes.
(Note: the beamer template was updated to match the LaTeX template, but
at this point verbatim in notes seems not to work in beamer.)
Closes#3361.
Thanks to Václav Haisman. This accompanies #3093.
This change allows users to set the default figure placement
for figures, instead of enforcing one choice.
Users with custom templates will need to add this.
Here's a minimal case:
\documentclass[]{article}
\usepackage{hyperref}
\begin{document}
\section{\%á}
\end{document}
Without this change, this fails on the second invocation of xelatex.
See https://tex.stackexchange.com/questions/313266/and-non-ascii-characters-in-headings
This affects inputs this like
# %á
with pdf output via xelatex.
Needed for correct polyglossia operation with Cyrillic fonts and perhaps
can find some other usages. Example usage in YAML metadata:
```
fontfamilies:
- name: \cyrillicfont
font: Liberation Serif
- name: \cyrillicfonttt
options: Scale=MatchLowercase
font: Liberation
```
