What’s this project

It’s a script that downloads my playlists and puts them into nice playlists (m3u files)

How to run

To extract source code in emacs use the org-babel-tangle (C-c C-v C-t)

Then run the the-playlist.bash script

Collecting playlists

Queue up commands that download video titles and attatch the m4a file extension and put in an m3u file in the appropriate place

commands=()

mkdir playlists

for playlist_name in ${!playlists[@]}; do
    echo "[THE PLAYLIST] Added $playlist_name to queue"
    commands+=("($download_playlists_function ${playlists[$playlist_name]} > playlists/${playlist_name}.m3u && echo \"[THE PLAYLIST] Generated \\\"$playlist_name\\\" playlist\") &")
done

Downloading Audio

Queue up commands that download audio from playlists “balatro” must be detected such that it’s tracks can be slowed down after downloading to play like it does in game

handle_balatro () {
    $download_audio_pl -o 'pool/tmp/%(title)s' $1
    cd "pool/tmp"
    balatro_list=($(ls))
    for track in ${balatro_list[@]}; do
	echo "[THE PLAYLIST] Slowing down balatro track: \"$track\""
	ffmpeg -y -i "$track" -strict -2 -filter:a "atempo=0.75" -vn "../$track"
    done
    cd "../.."
    rm "pool/tmp" -r
}
for playlist_name in ${!playlists[@]}; do
    echo "[THE PLAYLIST] Queued up $playlist_name playlist"
    if [ "$playlist_name" = "balatro" ]; then
	commands+=("(handle_balatro ${playlists[$playlist_name]} && echo \"[THE PLAYLIST] Finished downloading $playlist_name playlist\") &")
    else
	commands+=("($download_audio_pl -o 'pool/%(title)s' ${playlists[$playlist_name]} && echo \"[THE PLAYLIST] Finished downloading $playlist_name playlist\") &")
    fi
done

Executing commands

Up to this point we’ve built up a queue of commands. The commands get executed in a parallel way and in a way that when you press C-c (Ctrl-C) in the terminal, it exits propperly. This way also insures the terminal doesn’t hang (pretty nifty eh?)

(trap 'kill 0' SIGINT; eval ${commands[*]} wait)

Yup that’s it

Custom Playlists

Generates the everything playlist

rm -f playlists/everything.m3u
cat playlists/* > playlists/everything.m3u

Generates the “isaac” playlist

rm playlists/isaac
cat playlists/isaac* > playlists/isaac.m3u

Goals [1/7]

• [X] Fix Balatro Playlist
• [ ] Renaming specific vids according to id
• [ ] Have commands be a queue of getting filenames and downloading audio of individual vids so that I can implement sleeping as a workaround avoiding “Too many requests” error OR get rid of concurrent file downloading and use builtin workarounds in yt-dlp
• [ ] Use permanent Toby Fox Undertale and deltarune
• [ ] Fix the anime playlists (e.g. alternate ops, extended endings)
• [ ] Make the actual silksong playlist
• [ ] Drawn to life: The next chapter
• [ ] Human Resource machine (when I finish it)
