# Slackware build script for yt-dlp

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

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Note: I honestly prefer the standalone executable version of this,
# which I keep in ~/bin. It allows me to run "yt-dlp -U" as my user to
# get the latest version. However, since it's listed as a dependency
# for clipgrab, haruna, xdman, ytfzf, and an optional dependency for
# pipe-viewer, it has to exist on SBo.

# 20240217 bkw: switched to pythonhosted.org source tarball, thanks
# to Jeremy Hansen for finding this. Filename now has the version
# number in it, so no more caching problems for the download. Build
# had to change slightly as there's no more CONTRIBUTING file.
# 20240216 bkw: updated for v2023.12.30
# 20231219 bkw: updated for v2023.11.16
# 20231031 bkw: updated for v2023.10.13
# 20230904 bkw: BUILD=2, silence complaints from 'pip3 check'
# 20230711 bkw: updated for v2023.07.06
# 20230623 bkw: updated for v2023.06.22, added version check
# 20230402 bkw: updated for v2023.03.04
# 20230222 bkw: updated for v2023.02.17
# 20230104 bkw: updated for v2023.01.02

# 20230904 bkw: mixed signals from upstream. The README.md documents
# various python modules as optional, but some of them are listed in
# requirements.txt, meaning 'pip3 check' treats them as required,
# even though yt-dlp itself works fine without them. The fix is to
# remove the optional stuff from requirements.txt, to make it agreee
# with README.md. My own README documents these already. brotli and
# certifi are included in Slackware.
