lcpp - a C-PreProcessor for Lua 5.1 and LuaJIT ffi integration
This module offers a standard preprocessor for C code in pure Lua. The primary usecase is to enable LuaJIT ffi preprocessing. But you can also preprocess any other stuff (even Lua code itself)

Usage
-- load lcpp (ffi.cdef wrapper turned on per default) local lcpp = require("lcpp") -- just use LuaJIT ffi and lcpp together ffi.cdef("#include <your_header.h>") -- or compile some code by hand local result = lcpp.compile("...") local out = lcpp.compile([[ #define MAXPATH 260 typedef struct somestruct_t { void* base; size_t size; wchar_t path[MAXPATH]; } t_exe; ]])
