I'm trying to understand how to load a new set of language patterns in plain luatex. This far, I collect I have to do
%%% \directlua{ grc = lang.new() pattfile = io.open(kpse.find_file('grchyph.tex'), 'r') lang.patterns(grc, pattfile:read('*all')) pattfile:close() } \def\greek{\language\grc} \greek χαῖρε \bye %%% But then I don't know how to access the patterns with a language declaration. I'm sorry, but I fear the documentation is far too terse on this topic for a non-programmer. Any hints are welcome. Thanks in advance, Luis Rivera
