Adding a variable romanfont

[OvidiusCicero]

It would be nice to have a possibility to set the romanfont in xelatex/lualatex over a variable since mainfont actually oversets sansfont in headings

[jgm]

MANUAL.txt should also be updated (search for mainfont and mainfontoptions).

@OvidiusCicero Would you mind providing an example of how you're using this? I can't reproduce the situation that you describe in the original commit, and am wondering if there is a better way to solve it.

There is no documentation of romanfont in the fontspec manual. Setting both mainfont and romanfont with the standard classes gives unexpected results, with romanfont overwriting mainfont but only after inheriting its scale, which isn't likely the desired effect.

pandoc -o test.pdf --pdf-engine=xelatex << EOT

@adunning if you think this was a misguided change, then (after getting clarification from @OvidiusCicero) it would be good to open a new issue or PR, so this doesn't get lost.

@adunning @jgm You're right in so far that the problem seems to be burried in the pandoc template and not within fontspec which is what I seemingly misunderstood 9 months ago

Giving the whished result:

test.tex

\documentclass{scrartcl}

\usepackage{fontspec}

% Both work
%\setromanfont{Linux Libertine}
\setsansfont{Linux Biolinum}
\setmainfont{Linux Libertine}

\begin{document}

\section{Test should be in Linux Biolinum}
Text, should be in Linux Libertine

\end{document}

In Linux Biolinum

Hopefully reproducible minimum example:

test2.md

# Test should be in Linux Biolinum}

Text, should be in Linux Libertine

Compile with

pandoc test2.md -o test2.pdf --pdf-engine=xelatex --variable=mainfont:"Linux Libertine" --vari
able=sansfont:"Linux Biolinum"

Not in Biolinum

I ended up hardcoding it in my own temlpate

I'm on a Windows 10 machine. The fonts are installed on the system. Probably using old version of pandoc

You're seeing that because the scrartcl document class sets its headings in the sans-serif font, but by default Pandoc uses the article document class. You can set the document class as a variable to get the same result as your LaTeX file:

pandoc -o libertine.pdf -V mainfont="Linux Libertine" -V sansfont="Linux Biolinum" -V documentclass="scrartcl" --pdf-engine=xelatex << EOT

# Test should be in Linux Biolinum

Text, should be in Linux Libertine

EOT

If that solves your problem, I hope you wouldn't have any objections to removing the romanfont variable?

[OvidiusCicero]

Ah okay, that makes sense

I find romanfont to have clearer semantics in some cases but I do not object

[adunning]

Thank you! This will prevent it from unexpectedly changing the font size on someone.

There's no question that romanfont certainly does sound better, and makes much more sense with KOMA-Script in particular. It's strange that the option is completely undocumented.
