lua-include

If you want to use LuaJIT FFI with typical C #include statements.

Depends on:

• preproc-lua
• lua-ext
• lua-template
• LuaJIT

Uses the environment variable $LUAJIT_INCLUDE_CACHE_PATH for storing, otherwise uses $HOME/.luajit.include.

Example:

local ffi = require 'ffi'
local include = require 'include'
local stdio = include '<stdio.h>'
stdio.printf("testing %d\n", ffi.cast('int64_t', 42))

TODO:

• The cache stores by searched filename, but it would be nice if it could also first store by included filename, so that subsequent include's could get the correct file without doing a search (in case it's on a system where the C includes/compile is missing)
