About:
Blue Moon is an implementation of Lua. It is intended to provide superior integration in the long run with the BlitzMax object system, compared to the reference implementation. It uses a hybrid JIT/interpreter for its execution engine in the (vain?) hope of being somewhat faster than a pure interpreter would be.
Blue Moon is a completely original work, containing no code from PUC-Rio's stock Lua (designed against the language manual). Licence is MIT/X11, the same as stock Lua.
Blue Moon is a work in progress, and at the moment is extremely incomplete. Feel free to look at it, but many (most?) features are not implemented, and those that are present are not guaranteed to work correctly. A partial roadmap can be viewed in the issues file.
Blue Moon aims to implement Lua 5.3.
