# Slackware build script for straw-viewer

# 20210803 bkw: update for v0.1.3.
# 20201208 bkw: update for v0.1.2.
# 20201109 bkw: update for v0.1.1.
# 20201012 bkw: update for v0.1.0.
# 20200814 bkw: update for v0.0.7.
# 20200626 bkw: update to latest git. Which (for me anyway) works a lot better.
# 20200525 bkw:
# - update to latest git.
# - add patch to re-enable mplayer.
# - add note in README about new --api-host option.

# 20200310 bkw: update to not-quite-latest git. Next commit after 9089523
# removes mplayer support, which kinda sucks for Slackware users since
# mplayer ships with the OS (but mpv and vlc don't). My next update will
# likely re-add mplayer support, unless it's totally broken.

# 20200302 bkw: new build, based on youtube-viewer, of which straw-viewer
# is a fork. See https://github.com/trizen/youtube-viewer/issues/308 for
# why. Packaging a git commit because the latest (only) release has some
# issues that have been fixed.
