# playlistd

A daemon and API for automatically updating Subsonic playlists from Listenbrainz data

*Note: I've not actually tested this against Subsonic, only Navidrome*

## Building & running

This is a standard Rust project and should be uncomplicated to build and run. It does read some
environment variables:

* `SUBSONIC_BASE`, your Subsonic instance's API base. For navidrome users, this
  is `<protocol>://<host>/rest`
* `SUBSONIC_USERNAME`, your Subsonic username
* `SUBSONIC_PASSWORD`, your Subsonic password
* `DATABASE_URL`, the URL for a Postgres database
* `DAEMON_INTERVAL`, how often to update playlists

For deploying, these can be configured in `/etc/playlistd.toml`.

### Container build (Ubuntu 20.04)

`podman run --rm --network=host -v "$PWD":/mnt -w /mnt -e "DATABASE_URL=postgres://jude@127.0.0.1/navidrome-playlists" playlistd cargo deb`

## How to use

### Tracked playlist

A tracked playlist is a single Subsonic playlist that tracks data from Listenbrainz. For example,
a playlist that contains your top 15 songs from the past week.

These will work best when your music library is well organised with Musicbrainz metadata.

You can create a tracked playlist by inserting a row into the `tracked_playlist` table.

### Static playlist
