Jellyfin SmartPlaylist Plugin

Smart playlists with Lisp filter engine.

This readme contains instructions for the most recent changes in the development branch (main). To view the file appropriate for your version select the tag corresponding to your version. The latest version is v0.2.0.0.

How to use

After installing the plugin and restarting Jellyfin create a empty file in config/data/smartplaylists like this, maybe you want to generate a playlist of your favourite rock songs:

$ touch config/data/smartplaylists/Rock.yaml

Afterwards run the Task (re)generate Smart Playlists, this will rename the yaml file and populate it with some default values. You can now adjust the file to your liking. Go here to see more examples.

Id: Rock
Playlists:
- PlaylistId: 24f12e1e-3278-d6d6-0ca4-066e93296c95
  UserId: 6eec632a-ff0d-4d09-aad0-bf9e90b14bc6
Name: Rock
Program: (begin (invoke item "IsFavoriteOrLiked" (user)))
Filename: /config/data/smartplaylists/Rock.yaml
Enabled: true

This is the default configuration and will always match all your favorite songs (and songs which are in favourited albums).

To change the filter you can append a | (pipe) to the Program line and write multiline filters like this:

Porgram: |
  (begin
    (invoke item "IsFavoriteOrLiked" (list user)))

This is equivalent to the above example (not counting the other fields obviously).

Id

Arbitrary Id assigned to this playlist, can usually be left alone.

Playlists

A list of Playlist/User mappings. By default all users get an entry.

The ids must have the dashes in them as of now. To convert a id from without dashes to the canonical form run this command:

echo '<your id here>' | python3 -c 'import uuid; import sys; print(uuid.UUID(sys.stdin.read().strip()))'

To get your user id navigate to your user profile and copy the part after userId in the address bar.

PlaylistId

The id of the playlist that should be managed, must be owned by the corresponding user.

UserId

The user associated with this playlist.

Name

The name of the generated playlists, this is just a default value. If the user changes the name of their playlist the plugin will still work and remember the correct playlist.

Program

A lisp program to decide on a per item basis if it should be included in the playlist, return nil to not include items, return any other value to include them.

The configuration page defines some useful functions to make it easier to create filters. The above filter for liked items could be simplified to: (is-favourite).

Available definitions

lower: lowercases a string ((eq (lower "SomeString") "somestring"))
is-genre: check if the item is of this genre, partial matches allowed, the example filter would match the genre "Nu-Metal" ((is-genre "metal" (genre-list)))
is-genre-exact: the same as is-genre, but does not match paritally
is-favorite: matches a favorite item ((is-favorite))
is-type: matches the type of item look at BaseItemKind.cs for a list of items. The plugin has enabled support for Audio, MusicAlbum, Playlist ((is-type "Audio"))

Filename

The path to this file, only used internally and updated by the program.

Enabled

Enable this playlist, currently ignored.
