Hi, all,
I've read "The hyphen.cfg file for LuaTEX" (luatex-hyphen.pdf from
TL2012) and still don't understand is it possible to do not add language
to lualatex.fmt, by disabling it in language.dat.lua, but leaving it
enabled in language.dat.
The problem is that I want to dump old russian cyrillic hyphenation
patterns to latex, but don't want it to be in lualatex (with latex is
everything ok).
language-local.dat:
cyrillic loadhyph-ru-cyrl.tex
language-local.def:
\addlanguage {cyrillic}{loadhyph-ru-cyrl}{}{2}{3}
language-local.dat.lua:
["cyrillic"] = {
loader = 'loadhyph-ru-cyrl.tex',
lefthyphenmin = 2,
righthyphenmin = 2,
synonyms = { },
special = 'disabled:Not supported in luatex',
}
I update language config files:
tlmgr generate language
Then, I recreate fmt files. And when I compile
test document with lualatex, I see "cyrillic" language in listed patterns :
This is LuaTeX, Version beta-0.70.2-2012080612 (TeX Live 2012/W32TeX)

(./test.tex

ish, dumylang, nohyphenation, cyrillic, loaded.
(i:/texroot/texlive2012/texmf-dist/tex/latex/base/article.cls
....
and I still can access language counter \l@cyrillic.
So I understand, that language counter is increased anyway (it does not
check "special = 'disabled:'" before adding language to the list)
Is it possible to disable some how the language from dumping it to fmt
at all?
For example to write let say:
["cyrillic"] = null
????
In tex loadhyph-ru-cyrl.tex I disable it from dumping by testing the
engine, but the language counter is increased anyway and \l@cyrillic is
defined.
loadhyph-ru-cyrl.tex:
