Musicbee

An implementation of LocalLibrary for the MusicBee library manager. Reads library/settings files from MusicBee to load and enrich playlist/track etc. data.

Classes:

MusicBee(musicbee_folder[, playlist_filter, ...])	Represents a local MusicBee library, providing various methods for manipulating tracks and playlists across an entire local library collection.
XMLLibraryParser(path[, path_keys])	Parses MusicBee XML files to and from iTunes style XML.

class musify.libraries.local.library.musicbee.MusicBee(musicbee_folder, playlist_filter=(), path_mapper=PathMapper({}), remote_wrangler=None)

Bases: LocalLibrary, File

Represents a local MusicBee library, providing various methods for manipulating tracks and playlists across an entire local library collection.

Parameters:

• musicbee_folder (str) – The absolute path of the musicbee folder containing settings and library files.

• playlist_filter (Union[Collection[str], Filter[str]] (default: ())) – An optional Filter to apply or collection of playlist names to include when loading playlists. Playlist names will be passed to this filter to limit which playlists are loaded.

• path_mapper (PathMapper (default: PathMapper({}))) – Optionally, provide a PathMapper for paths stored in the playlist files. Useful if the playlist files contain relative paths and/or paths for other systems that need to be mapped to absolute, system-specific paths to be loaded and back again when saved.

• remote_wrangler (RemoteDataWrangler (default: None)) – Optionally, provide a RemoteDataWrangler object for processing URIs on tracks. If given, the wrangler can be used when calling __get_item__ to get an item from the collection from its URI. The wrangler is also used when loading tracks to allow them to process URI tags. For more info on this, see LocalTrack.

load_tracks()

Load all tracks from all the valid paths in this library, replacing currently loaded tracks.

Return type:

None

save(dry_run=True, *_, **__)

Generate and save the XML library file for this MusicBee library.

Parameters:

dry_run (bool (default: True)) – Run function, but do not modify the file on the disk.

Returns:

dict[str, Any] – Map representation of the saved XML file.

static generate_persistent_id(value=None, id_=None)

Generates a valid persistent ID from a given value or validates a given persistent ID as given by id_,

Parameters:

• id – A persistent ID to validate

• value (str | None (default: None)) – A value to generate a persistent ID from.

Returns:

str – The valid persistent ID.

Raises:

MusicBeeIDError – When no id_ and no value is given, or the given id_ is invalid.

classmethod track_to_xml(track, track_id, persistent_id=None)

Convert a local track into a dict representation of XML data for a MusicBee library file

Parameters:

• track (LocalTrack) – The track to convert.

• track_id (int) – An incremental ID to assign to the track.

• persistent_id (str | None (default: None)) – An 16-character unique ID to assign to the track.

Returns:

Raises:

MusicBeeIDError – When the given persistent_id is invalid.

• tracks (Mapping[LocalTrack, int | Sequence[int, str]] | list[LocalTrack]) – A map of all available tracks in the library to their track IDs, or a simple list of tracks. If a map is given and the values are Sequence, take the first index as the Track ID. If a list is given, the function will use the track’s index as the Track ID.
