I can’t guess what you’re up to but if it’s going to eventually become a module, the “chessfss” table should not pollute the global namespace. There are canonical locations (check luat-ini.lua) where the functions and data should go: http://www.ntg.nl/pipermail/ntg-context/2010/054982.html So you might be better off dropping “require” altogether and just conclude your module with a line like: thirddata = thirddata or { } thirddata.chessfss = chessfss instead of returning a table, then loading it with “loadluafile”.
