* LaTeX template: Use `pgfpages` package; this is needed for notes on second screen in beamer
* LaTeX template: Add `beameroption` variable in template
The resulting PDF can be verified using the Apache PDFBox preflight app.
```
$ java -jar preflight-app-2.0.8.jar test.pdf
The file test.pdf is a valid PDF/A-1b file

Instructions on how to install the ICC profiles on ConTeXt standalone can be found in the wiki: <http://wiki.contextgarden.net/PDFX#ICC_profiles>.
If the ICC profiles are not available the log will contain messages like these
```
backend > profiles > profile specification 'sRGB.icc' loaded from '/usr/local/texlive/2017/texmf-dist/tex/context/colors/icc/context/colorprofiles.xml'
backend > profiles > error, couldn't locate profile 'srgb.icc'
backend > profiles > no default profile 'srgb.icc' for colorspace 'rgb'
backend > profiles > profile specification 'sRGB IEC61966-2.1' loaded from '/usr/local/texlive/2017/texmf-dist/tex/context/colors/icc/context/colorprofiles.xml'
backend > profiles > error, couldn't locate profile 'srgb.icc'
backend > profiles > invalid output intent 'sRGB IEC61966-2.1'
```
and the resulting PDF will not be valid PDF/A:
```
$ java -jar preflight-app-2.0.8.jar test.pdf
The file test.pdf is not a valid PDF/A-1b file, error(s) :
2.4.3 : Invalid Color space, The operator "g" can't be used without Color Profile on page 1
2.4.3 : Invalid Color space, The operator "G" can't be used without Color Profile on page 1

However, the PDF will still be generated and the "errors" shown in the log do not break anything.
* Provide `bidi` package's option using `\PassOptionsToPackage`. This avoid clash when `polyglossia` loads it first and then it is loaded again for XeLaTeX when `latex-dir-rtl` defined.
* Adjust test suite for LaTeX template change.
instead of relying on CSS. Closes#4162. HTML-based templates have had
the custom CSS for div.line-block removed. Those maintaining custom
templates will want to remove this too.
We still enclose line blocks in a div with class line-block.
This ensures that we don't use $..$ delimiters, which
gives bad results when $ is used as a currency sign.
This depends on the current dev version of reveal.js.
* Move as much as possible to the CSS in the template.
* Ensure that all the HTML-based templates (including epub)
contain the CSS for columns.
* Columns default to 50% width unless they are given a width
attribute.
Closes#4028.
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.
Beamer loads `xcolor` rather than `color`, and thus the `dvipsnames` option doesn't take effect. This also provides a wider range of colour selections with the `svgnames` option. Closes#3877.
...by using the `luatexja-fontspec` and `luatexja-preset` packages. Use
existing `CJKmainfont` and `CJKoptions` template variables. Add
`luatexjafontspecoptions` for `luatexja-fontspec` and `luatexjapresetoptions`
for `luatexja-preset`.
The structure expected is:
<div class="columns">
<div class="column" width="40%">
contents...
</div>
<div class="column" width="60%">
contents...
</div>
</div>
Support has been added for beamer and all HTML slide formats.
Closes#1710.
Note: later we could add a more elegant way to create
this structure in Markdown than to use raw HTML div elements.
This would come for free with a "native div syntax" (#168).
Or we could devise something specific to slides
Avoids an options clash when loading a package (e.g. `tufte-latex`) that uses `hyperref` settings different from those in the template (introduced in <feffd7c64a>).
Changed markdown, rtf, and HTML-based templates accordingly.
This allows you to set `toc: true` in the metadata; this
previously produced strange results in some output formats.
Closes#2872.
For backwards compatibility, `toc` is still set to the
toc contents. But it is recommended that you update templates
to use `table-of-contents` for the toc contents and `toc`
for a boolean flag.
This is a thin wrapper around mathjax that makes math look better
on revealjs.
See https://github.com/hakimel/reveal.js/#mathjax
We do this by setting the 'mathjax' boolean variable and
using it in the revealjs template. Also, for revealjs
and mathjax, we don't assign the usual thing to the 'math'
variable, since it's handled by mathjax config.
Closes#3743.
* LaTeX: Load `parskip` before `hyperref`.
According to `hyperref` package's `README.pdf`, page 22, `hyperref` package
should be loaded after `parskip` package.
* Adjust tests for previous change.
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.
We now issue `<div class="line-block">` and include a
default definition for `line-block` in the default
templates, instead of hard-coding a `style` on the
div.
Closes#1623.
Closes#3547.
Macro definitions are inserted in the template when there is highlighted
code.
Limitations: background colors and underline currently not
supported.
Modified template to include a `<back>` and `<body>` section.
This should give authors more flexibility, e.g. to put
acknowledgements metadata in `<back>`. References are
automatically extracted and put into `<back>`.
