Use Item.destination method for generation of relative paths to media
files in playlist. The fragment keyword enables returning the path as
unicode instead of bytes, let's keep that in mind.
- Improve --help text
- Use unicode instead of bytes when adding media file paths to the
playlist file.
- The "standard" (?) of m3u8 defines that unicode should ensure support
of special characters in media file names. util.displayable_path() is
used to do the conversion from bytes. We save everything in bytes in
the config since it seemes to be the way this plugin or beets in
general likes to save paths.
- Join dest and playlist in the config reader method already to have it
ready in both methods that require the full path to the playlist file.
- Similar to what the Spotify plugin does, on imports we save to a field
`..._album_id` (spotify_album_id, deezer_album_id, beatport_album_id)
- It would be good to submit such a change to the 3rd-party plugins beetcamp
and beatport4 as well (beatport_album_id, bandcamp_album_id).
- We might need to investigate why none of these
flex attr fields get populated to the beets album level (`beet info -a`,
album_attributes db table), it is only available at the item level (`beet
info`, item_attributes db table). This should be tackled in a future
issue/PR.
- Bandcamp, Spotify, Deezer and Beatport ID's are saved in the library as
flexible attributes.
- On _reimports_ the method importer.ImportTask.reimport_metadata() takes care
of preserving existing values for flexible attributes instead of applying new
(and potentially empty) values.
- In this case we don't want this behaviour and need to make sure that new
values are applied. Therefore we check whether such ID's of metadata services
are present in the reimported items and exclude them in reimport_metadata().
- By default no external URLs will be looked for in the 'url-relation-list' of
the releae dictionary.
- Enabling is possible per each external service.
- Enable fetching 'url-rels' from the MusicBrainz release endpoint.
- A MusicBrainz release might contain a link to a Discogs release
which we save to the discogs_albumid attribute of the info object.
- For extraction of the release ID from the Discogs URL, we use the method
provided in the id_extractors util module.
