bit32 library backported for Lua 5.1.4
Here's a version of the bit32 library from Lua 5.2.0, fully back-ported to Lua 5.1.4:
On my linux and Mac OS X x86 systems, it passes all the bitwise.lua tests from the Lua 5.2.0 test suite.ysdl
ysdl is a lightweight SDL binding for Lua 5.1.x. Depending on what you are looking for, it may or may not be of interest to you.
Advantages:
- simple: only a single C file to include in your application
- small: many of the most common SDL functions are bound, but not all of them, so the binding isn't larger than Lua itself
- includes functions from SDL, SDL_image, SDL_mixer, and SDL_ttf
- Lua function names closely match their SDL counterparts, with predictable changes
- MIT-style licensing
- fast: very little type and error checking is done
Disadvantages:
- unforgiving: very little type and error checking is done; if you pass the wrong argument to a SDL function, you will crash
- small: if you need something that isn't yet bound, you'll have to add a binding yourself
- not all SDL functions are bound
- documentation is minimal
In other words, if you're looking for a complete, hand-holding SDL binding, this isn't it. If you'd like a simple, lightweight SDL binding, and don't mind occasionally adding things on the C side, then ysdl might work for you.
