# Slackware build script for solarwolf

# Written by B. Watson (urchlay@slackware.uk)

# 20260806 bkw:
# - update for v1.6.0.
# - new homepage/download (pygame.org is dead).
# - use python3 and python3-pygame.

# 20230107 bkw: BUILD=3, ARCH=noarch.

# 20211228 bkw: BUILD=2.
# SDL2_mixer on -current utterly lacks support for tracker music
# (.mod, .it, .xm, etc). This game's music is in .xm format... so
# unless/until Pat adds support in SDL2_mixer, this script works
# around it by using timidity to convert the .xm music to .ogg, which
# SDL2_mixer can handle.
# Add TiMidity++ as a dep, to make this work. It's really only
# build-time, not runtime.
# Also, new-style icon.

# TODO: scaling in fullscreen mode. our pygame is built with SDL2,
# this should be possible.

# 20260806 bkw: Our SDL2 can't play .xm files, so convert them to
# something we *can* play. First, patch the code before installing.
# I was hoping that, since we're using a newer pygame (python3-pygame
# 2.5.2), it had some other way to play .xm files... but no, this is
# still necessary.
# 20211228 bkw: make the game play the converted .ogg music.

# 20211228 bkw: convert the music to .ogg. Use separate oggenc instead
# of timidity's -Ov, so we can set the bitrate to 64k (to match the
# one .ogg file shipped with the source). This bloats the package by
# 30%, but it still comes out to less than 4MB total, so no problem.
