TLC, a tiny lua cocoa bridge

Is it using LuaJIT or any another ffi library?

James McKaskill ported LuaJIT's FFI to standard (PUC) Lua, but there are a few differences. I don't know for which one it was developed.

Yes, it does indeed require LuaJIT. (I probably should indicate this more clearly in the source)

Did you try it in vanilla Lua with the FFI port linked in a sibling of your post?

Nope, can't say I have.

It's LuaJIT (FFI). Legacy wrappers involve mostly C code and a lot of code managing metatables.

I know exactly zero Lua, but

  if ffi == nil then
  	ffi = require("ffi")
  end

is suggestive.

There are some idioms in Lua that you might recognize from Python or Ruby. I have seen this one in Perl and the Bourne shell, as well.

  ffi = ffi or require("ffi")

If the ffi expression evaluates to something that is not nil, we keep the previous value of ffi. The assignment becomes a no-op.

If it evaluates to a nil, we initialize it by calling require().
