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?

\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
