GNU Guile-SDL
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 2.0.26 (by Andreas Schiffler) and
bindings for it.

Latest release:
0.6.1 (2022-02-20)
changes to ‘
(sdl misc-utils)
new proc: ‘
create-rgba-surface
This returns a new 32bpp surface of the specified
width and height w/ the ‘
src-alpha
’ flag
set.
new proc: ‘
create-rgba-square
This returns a new 32bpp square surface of the
specified edge length w/ the ‘
src-alpha
flag set.
rotate-square
’ fixed / extended
Previously, this proc made reference to
roto-zoom-surface
’ in the wrong module.
This undefined reference was never detected, showing how
middlig to poor the test coverage was (and remains). Now,
roto-zoom-surface
’ is properly imported
from ‘
(sdl gfx)
’.
Another oddity is that previously, the specified ANGLE
argument was subtracted by 90 prior to passing it to
roto-zoom-surface
’. This bizarre practice
is no more.
Re extension, ‘
rotate-square
’ now takes
optional 3rd arg MKSQUARE which specifies a procedure to
make a new square surface. If omitted, it defaults to
create-rgba-square
’.
Additionally, if the rotated surface has flag
src-alpha
’ set, the resizing blit uses
(sdl gfx) blit-rgba
’ to do the job
(otherwise ‘
(sdl sdl) blit-surface
’, as
before).

Documentation
Documentation for Guile-SDL
is available
online, as is
documentation for most GNU
software
. You may also find information about Guile-SDL by
running
info guile-sdl
or by looking at
/usr/share/doc/guile-sdl/
/usr/local/share/doc/guile-sdl/
, or similar
directories on your system.
Mailing Lists
Guile-SDL has the following mailing lists:
bug-guile-sdl
is used to discuss most aspects of Guile-SDL, including
development and enhancement requests, as well as bug reports.
Announcements about Guile-SDL and most other GNU software are
made on the
info-gnu
mailing list (
archive
).
Security reports that should not be made immediately public
can be sent directly to the maintainer. If there is no response
to an urgent issue, you can escalate to the general
security
mailing list for advice.
Getting involved
Development of Guile-SDL, and GNU in general, is a volunteer
effort, and you can contribute. For information, please read
How to help GNU
. If you'd like to get
involved, it's a good idea to join the discussion mailing list
(see above).
