usage_description="
|
|
Iterates over and commits all downloaded Spotify playlists in \$PWD or playlists/ directory,
|
|
showing diffs and then committing each in turn
|
|
|
|
First shows only the net removals in standard Spotify URIs + Track Name for a playlist
|
|
to check if anything has been lost from a playlist (additions don't need as much scrutiny)
|
|
|
|
Drastically reduces net removals list for human review by omitting duplicate URI removals
|
|
(checks if URI is present in the spotify format playlist) or URI replacements for same song
|
|
(either URI remapping or single vs album)
|
|
|
|
If there are no net removals then auto-commits the playlist
|
|
|
|
Otherwise shows the list of net removals in both Spotify URI and Track name formats
|
|
followed by the full human readable playlist diff and spotify URI diff underneath
|
|
|
|
If satisfactory, hitting enter at the end of the playlist diff will commit both
|
|
the Spotify URI and human readable playlist simultaneously
|
|
|
|
Requires DevOps-Perl-tools to be in \$PATH for diffnet.pl
