Hi all!
(I assume this is the appropriate list for
questions regarding luatex-plain.)
I am trying to enable the Russian hyphenation patterns. The demo
code below works with luatex.fmt but not luatex-plain.fmt (both
from tex live).
More precisely, after loading the hyphenation patterns for, say,
*Latin* I get proper hyphenation. Now when I attempt the same
with *Russian*, nothing is hyphenated. (As lang.patterns(id)
correctly returns the patterns in both cases, I guess something
is missing after updating tex.language.)
Any thoughts? Can someone reproduce this?
Philipp
=================================================================
\def\loadpatterns#1{%
\directlua{
local pattern_source = kpse.find_file"#1"
texio.write_nl("* loading patterns from file " .. pattern_source)
local fh = io.open(kpse.find_file"#1")
local new_patterns = fh:read"*a"
fh:close()
local new_language = lang.new()
lang.patterns(new_language, new_patterns)
tex.language = lang.id(new_language)
%print(lang.patterns(new_language))
}%
}
% ····························································· %
\showhyphens{Циолковский} %% no pattern yet, so both without
\showhyphens{Oenothea} %% hyphenation
% ····························································· %
\loadpatterns{hyph-ru.pat.txt} %% Russian
\showhyphens{Циолковский} %% wrong with luatex-plain
% ····························································· %
\loadpatterns{hyph-la.pat.txt} %% Latin
\showhyphens{Oenothea} %% correct with either

Hans, thanks a lot for this. A while ago I spent half a day to import the language system from Context but to no avail. The code you posted seems to fit my need exactly, for the moment anyways!

Will this become part of of the format eventually? I've added the files. After all luatex-plain is our official plain benchmark and patterns are part of the game.
