Guile-SDL

What is it?

Guile-SDL is a set of modules that provide bindings for SDL (Simple DirectMedia Layer) to enable Guile programmers to do all the nice things you can do with SDL. Its core was originally written by Alex Shinn, Vikram Subramanian, and Joel Smith.

Most of the SDL functions have been wrapped with the exception of a few functions that were too C-centric. The SDL Threads and the Audio functions haven't been included because of the problems with Guile code being run from more than one thread. However audio programming can be done with the module‘(sdl mixer)’ that requires the SDL_mixer library.

Also included is SDL_gfx 2.0.22 (by Andreas Schiffler) and bindings for it.

Guile-SDL is released under the GNU GPLv3+ along with a fully-indexed manual in texinfo format (i.e., the source for the online documentation).
