Returns track URIs for the given Spotify public playlist
|
|
|
|
Playlist argument can be a playlist name (a regex which will return the first matching playlist)
|
|
or a playlist ID (get this from spotify_playlists.sh)
|
|
|
|
\$SPOTIFY_PLAYLIST can be used from environment if no first argument is given
|
|
|
|
Spotify track URIs can be used:
|
|
- as backups to restore a playlist's contents
|
|
- copied to new playlists
|
|
- set to Liked (spotify_set_track_uris_to_liked.sh)
|
|
|
|
Requires \$SPOTIFY_ID and \$SPOTIFY_SECRET to be defined in the environment
|
|
|
|
Caveat: due to limitations of the Spotify API, this by default only works for public playlists. For private playlists you must get an interactively authorized access token like so:
|
|
|
|
export SPOTIFY_ACCESS_TOKEN=\"\$(\"$srcdir/spotify_api_token_interactive.sh\")\"
|
|
"

|
|

|

usage "playlist id not defined"
|

|
|
|
