usage_description="
|
|
Uses Spotify API to translate a Spotify public playlist name to ID
|
|
|
|
Returns the ID for first playlist in your account which name contains the given playlist name (case insensitive substring match for convenience)
|
|
|
|
If you want an exact full string match of the playlist name to guarantee you get the right playlist ID, then export SPOTIFY_PLAYLIST_EXACT_MATCH=1
|
|
|
|
If a Spotify playlist ID is given, returns it as is (this is for coding convenience when calling from other scripts)
|
|
|
|
Needed by several other adjacent spotify tools
