Re: Pretest: format generation fails

Hi Marc - thanks for the report. What specifies the langauges to be
built into the formats are the files language.dat (for latex formats) and
language.def (for plain formats, excluding "tex" itself, which only
loads Knuth's hyphen.tex), and language.dat.lua (for lua).
E.g., for me I have:

/usr/local/texlive/pretest/texmf-dist/tex/generic/config/language.dat
/usr/local/texlive/pretest/texmf-dist/tex/generic/config/language.def

But there can also be versions in texmf-var (same subpath) overriding
those system files (which have everything). In your case, I expect there
are, and they did not copied or applied when updating the pretest.

I see my instructions on pretest.html only talk about copying texmf-dist
and texmf-local. I don't think we'd want to copy all of texmf-var, but I
guess those particular files need to be.

I'm sorry I have only these vague clues, but ... I hope this makes
some kind of sense.  You can check to see what language.d* files you've
got with, e.g.,
kpsewhich --all language.dat

Thanks,
Karl
