[Sakala-devel] SDL and Common List

[Brian C. <ubergeek@Dartmouth.EDU>]

OK, I got most of the initialization stuff ported from 
Objective-C to Lisp. I actually got that working during the bus 
ride up here (ahh, laptops are nice). So I can now open a black 
window, and it crashes as soon as you close it (which is better 
than crashing as soon as you call SDL_Init). I've been busy with 
moving in and getting settled into class since then, so I 
haven't worked on it since then, but I think that I'll try to 
see if drawing in that window works next.

Once I've done that, I think that we need to come up with a 
nice, clean interface to SDL in portable common lisp and provide 
the implementation for CMUCL and OpenMCL. While theoretically 
CL-SDL should have such an interface, it seems to be just the 
definitions of the foreign functions, which OpenMCL does 
automatically, although with different names. So we could either 
write CL-SDL as it should be, or just make a nice, portable 
interface to the drawing functions we need, and leave it at 
that. Which do you prefer? Whatever we do, we should probably 
split all of the platform dependent stuff into a separate 
package, so it will be nice and isolated.
