Hello, I tried out beta 0.11.2 yesterday, and it works great. Still, I noticed a few things that do not seem right. First thing: I tried to use 'require', and the error message I got was slightly weird:

...

...

! LuaTeX error [string "luas[0]"]:1: module '/Dokumente/Writing/trunk/Writing/T eX/tex/KTeX/lua/l-callback.klua' not found: no field package.p. \LU:require ...ed {require(kpse.find_file('#2'))}} <<<

I look into Lua 5.1.2 and found this in loadlib.c:

...

...

lua_pushfstring(L, "\n\tno field package.preload['%s']", name); <<<

A variation (shorter pathname, thus longer message):

...

...

! LuaTeX error [string "luas[0]"]:1: module 'l-callback.klua' not found: no field package.preload['l-callback.klua'] no file './l-callback/k. <<<
