Re: [ANN] luaclang - a Lua binding to the Clang API to parse C/C++ files

[Graham Wakefield <wakefield@...>]

Nice.  Did you know about our Lua/Clang binding?
https://github.com/grrrwaaa/luaclang

Different features/motivations of course; we've been concentrating on using it for the JIT compilation of C++ code, and recently I've been playing with the C-binding to LLVM via LuaJIT's FFI. An FFI-to-clang-c is in the works.

Perhaps there's an opportunity to merge efforts?
