[bug#49408] [PATCH core-updates 1/5] gnu: TeX Live: Use IniTeX to build


From: Thiago Jung Bauermann
Subject: [bug#49408] [PATCH core-updates 1/5] gnu: TeX Live: Use IniTeX to build a couple of packages
Date: Sun, 4 Jul 2021 21:00:59 -0300

The package texlive-latex-base in TeX Live 2021 will depend on
texlive-latex-l3kernel and texlive-latex-l3packages. Therefore we need to
remove their build dependency on texlive-latex-base to avoid a circular
dependency.

l3kernel and l3packages don’t need LaTeX during build, just IniTeX.
So to make them use it, modify texlive-build-system to allow disabling
the #:texlive-latex-base and #:tex-format parameters, and also add
a #:tex-engine parameter.

We also need to add texlive-docstrip as a native input, which was
previously provided by texlive-latex-base.

* gnu/packages/tex.scm (texlive-latex-l3kernel,
texlive-latex-l3packages)[arguments]: Add ‘#:tex-engine’, ‘#:tex-format’
and ‘#:texlive-latex-base’ parameters.
[native-inputs]: Add ‘texlive-docstrip’.
* guix/build-system/texlive.scm (lower)[build-inputs]: Don’t add
‘texlive-latex-base’ if its keyword parameter is false.
(texlive-build): Add ‘tex-engine’ keyword parameter.
[builder]: If a ‘tex-engine’ parameter was passed, use it. Otherwise, use
‘tex-format’ as the engine.
* guix/build/texlive-build-system.scm (compile-with-latex): Add ‘engine’
parameter. If the ‘format’ parameter is false, add “-ini” option to the
command line.
(build): Add ‘tex-engine’ parameter. Pass it down to ‘compile-with-latex’.
