LuaX no longer maintained? I tried it some time ago
(probably year
2006). It definitely is good software with many
powerful packages
linked in. At that time my interest was a tiny (<500k)
cross platform
GUI + Lua solution. But it turns out that doing GUI on
SDL is not
that sort of thing I imagined.
Back to murgaLua. It's tiny but it's not fltk2. And
fltk2 looks like
progressing very slowly (e.g. fl_table). For GUI
bindings, tcltk is
probably more powerful especially they now have native
OS support.
On game scripting engines, how about luaplayer on PSP?
