LaTeX export: grffile is a stub package

LaTeX export: grffile is a stub package

[meedstrom]

According to https://ctan.org/pkg/grffile, since 2019-11-08, grffile is a stub that just loads graphicx, part of texlive-latex-graphics, part of texlive-base.  My system (Guix) doesn't have a package for grffile, so I can't generate a PDF, which is silly because it's a stub anyway.

Suggest fixing by removing \usepackage{grffile} in LaTeX export.

A caveat: some distributions seem to still package an old TeXLive full distribution, going by Guix which provides a three-gigabyte "texlive" package from 2019-04-10.  I'm not sure what sort of deprecation time we allow.

Oh, that reminds me, we can also get rid of texcomp.

I’ve had this in my config for a while, but I’ve done so much to the LaTeX
export that I forgot about it 😛.

All the best,

Perhaps it can be tested in runtime by

     kpsewhich grffile.sty

Well, it’s a small thing so I whipped up a patch 🙂.

grffile is a deprecated LaTeX package, but it is included in TeX live
2021 (Arch). The Arch version of TeXlive is identical to the official
version (except that it does not include the documentation, which must
be installed using an AUR package). My recommendation: unless you are in
Arch or one of its derivatives, it is better to always install *the
official and lastest version* of TeX live (with its own installer and
its own package manager); the versions included in the repositories of
many distros (except for Arch and very few others) are usually outdated
or incomplete, and it is better to avoid them. The current version of
TeXlive is TeXlive 2021. There is, by tradition, a version per year and
in each one many things are modified and quite bugs fixed.

Best regards,

Juan Manuel

Hmmm... one note about xcolor in your list: Some configuration options
are load-time options that have to be set as package load options. If
xcolor is already loaded with no options, its much harder to load it
with special options like [table,svgnames*]. Also some classes like
beamer are very special with reagads to xcolor.

But what about some other tweaks?

To better support lualatex and xelatex in the default configuration,
we should add

    ("" "fontspec" t ("lualatex" "xelatex"))

Personally, I would also add the following two lines for better
multilingual support with all three engines:

    ("AUTO,safe=none,math=normal" "babel" t ("pdflatex" "lualatex"))
    ("AUTO" "polyglossia" t ("xelatex"))

Then, for math it may be nice to substitute "amsmath" with "mathtools"
and for lualatex and xelatex add something like this:

    ("warnings-off={mathtools-colon,mathtools-overbracket}" "unicode-math" t ("lualatex" "xelatex"))

What do you think?
