Never mind, I solved the problem. I'll describe what I did here, in
case anyone finds it helpful down the road.
First, I figured out how to create lang-foo.lua manually -- which wasn't
too painful, since the hyphenation rules for the language are very
simple -- and found that Context uses it if it sits next to the file
that uses \language[foo].
Then, after some detective work, I found that I can generate
/bar/lang-foo.lua from /foo/hyph-foo.tex by running the following
command:
mtxrun --script patterns --convert --path=/foo --destination=/bar \
--specification=foo,hyph-foo,Foobar
This prints a lot of errors ("no valid file", "convertion aborted")
because, after converting hyph-foo.tex, mtx-patterns.lua tries to
convert everything in its hard-coded list, but that's not a big deal.
Besides lang-foo.lua, which is all I really need, I also get
lang-foo.rme, lang-foo.hyp, and lang-foo.pat; the latter two are for
mkii, I gather.
Would a patch for mtx-patterns.lua that adds an option to convert *only*
a particular language's file be useful? I'm thinking an option like
--only that one can use like this:
mtxrun --script patterns --convert --path=/foo --destination=/bar \
--only \
--specification=foo,hyph-foo,Foo \
--specification=bar,hyph-bar,Bar \
The simplest implementation would be to clear the list first (if --only
is used), then add foo and bar to it. Something like this:
