README excerpt:
This is a collection of small programs released
under GNU GPL v3 that use Guile-SDL, available at:
http://www.nongnu.org/guile-sdl/
NB: These require Guile-SDL 0.4.0 or later.
NEWS excerpt:
- 3.0 | 2011-12-22
- programs can be run from anywhere
Previously, programs had to be invoked from their own directory,
to able to find their data files (i.e., they looked in ".").
Now, they look in ‘(dirname (car (command-line)))’. Note that
this will fail for symlinks, so if you want to "install" a
program in ~/bin, for instance, the best way is to create a
small shell wrapper:
#!/bin/sh
exec /path/to/guile-sdl-demos-3.0/PROG/PROG "$@"
Perhaps we will support "make install" in a future release...
- programs can be run w/o args
Previously, such functionality lived in the top-level driver
script ‘demo’ and some programs would barf if run w/o args.
- ‘make check’ support
The command "make check" runs all the demo programs without args.
- changes to driver script ‘demo’
- license now GPLv3+
It used to be GPLv3 (without the "any later version" option).
- /bin/bash no longer required
/bin/bash was to implement ‘unpicasso --random’ support, but
that's moved into unpicasso proper.
- new option ‘--version’
This displays the Guile-SDL Demos version and exits successfully.
- changes to demo ‘view-vcg’
- VCG files cleanup
There were two long-standing ‘\D’ in the VCG files.
Who knows how they got there?
- workaround for Guile 1.8.7 (ice-9 popen) bug
Previously, view-vcg used ‘open-input-pipe’ for gathering the
output of the sed(1) command used as part of reading the vcg
file. Unfortunately, Guile 1.8.7 does not return all of the
subprocess output for some of the larger vcg files, so now we
filter in two steps, via a temporary file, and avoid pipes
altogether (sigh).
- geometry defaults to 300x400
- option ‘--batch’ dropped
The program is now always interactive.
- changes to demo ‘unpicasso’
- if given a directory, scan it for images
A file is recognized as an image if its name has one of the
extensions (portion after last "."): gif, png, jpg, ppm.
- new option ‘--random’
This option makes unpicasso run the command ‘locate *.jpg’
and randomly choos one of the resulting directories for
scanning (as described above).
You need a working locate(1) installed on the system.
- new demo ‘mq’
This program highlights the difference between KEYUP and KEYDOWN
events, w/ some alpha blending and fancy blit ordering mixed in.
