sdl2-ffi

A LuaJIT interface to SDL2

Installation

First, make sure SDL2 is installed on your system. This package only requires the binary shared libraries (.so, .dylib, .dll). Please see your package management system to install SDL2. You can also download yourself binaries on the SDL2 web page

luarocks install https://raw.github.com/torch/sdl2-ffi/master/rocks/sdl2-scm-1.rockspec

Note: this SDL interface supports only SDL2, not SDL 1.2.

Usage

local sdl = require 'sdl2'
sdl.init(sdl.INIT_VIDEO)
...

All SDL C functions are available in the sdl namespace returned by require. The only difference is the naming, which is not prefixed by SDL_ anymore. The same goes for all C defines (like SDL_INIT_VIDEO, which can now be accessed with sdl.INIT_VIDEO).

Although the interface is quite complete, there are still few defines not ported in this package. Fill free to post a message about it, or to request pulls.
