> Interesting, I would like (besides fixing the current problem) to implement some debuging facilities in my project. Can you give some more details?
In specific, the lua_getinfo function in the API can get code fragments out
lua_getinfo(L, ">S", &ar);
printf("%s", ar.source);
There's also plenty of info in the manuals, and on the wiki.
