Quick Start

If you're just looking for how to use this program, read INSTALL and, if you want an MPD client, contrib/INSTALL.lastmp.

HOWTO Write Client Plugins for lastfmsubmitd

lastfmsubmitd is designed to handle the Last.fm protocol, so that every player plugin does not need to re-implement it. Player plugins that use lastfmsubmitd only need to determine when a song has been played and drop its information in lastfmsubmitd's spool directory. After doing so, the player plugin can forget about it -- If the network is down, or even if lastfmsubmitd is not running, the contents of the spool will be saved until they can be submitted.

To send song information to lastfmsubmitd, you can do one of the following:

  • Fork and exec /usr/lib/lastfm/lastfmsubmit. lastfmsubmit fills a role similar to sendmail(1). It will take the song specified on the command line with --artist, --title, --length, and optionally --album and --mbid, and encode it in UTF-8 YAML. Then, it will write it to lastfmsubmitd's spool or stdout. The primary purpose of this program is to abstract character encoding and YAML document creation; all your player plugin needs to do is detect a song and invoke lastfmsubmit. Of course, you can also run it manually should something go wonky.

  • Use the lastfm Python module. Example code::

    import time import lastfm

    get your song from somewhere...

    song = {'artist': 'New Order', 'title': 'Your Silent Face', 'album': 'Power, Corruption & Lies', 'mbid': '3a54b3b2-6037-4fc3-a7a0-ead924e55ea2', 'length': 359}

    cli = lastfm.client.Client('demo') cli.open_log()

    determine that your song has been played...

    song['time'] = time.gmtime()

    cli.log.info('Played song: %s' % lastfm.repr(song)) cli.submit(song)

    You can also supply a custom configuration, like this::

    cli = lastfm.client.Client('demo', lastfm.config.Config('/path/to/demo.conf'))

    Documentation for each of these functions can be read using pydoc.

  • Write a file to /var/spool/lastfm yourself. Submission files contain simple data structures serialized as YAML_. You can use a YAML implementation such as Syck_, as long as it is UTF-8 clean. Alternatively, you can print the data yourself. Example data::


    artist: "The Jam" title: ""A" Bomb in Wardour Street" album: "All Mod Cons" length: 201 mbid: b7ec9e64-baa4-49bc-ad33-570919d01ba1 time: !timestamp 2006-03-23 13:42:25

    Make sure any non-ASCII characters are converted to UTF-8. If a string contains double-quotes, as above, they must be escaped with backslashes. Any literal backslashes must be escaped as well.

    If you have multiple submissions, you can write them all in one file. Each file in /var/spool/lastfm should be created with a unique name; mkstemp(3) is a good way to do this.

Examples

An example client for MPD called LastMP is included in the contrib directory; it uses the Python API. It is probably the most popular lastfmsubmitd client; the author, an MPD user, created lastfmsubmitd specifically so that he could write it.

Notes about this fork.

At some point scrobbling songs on Libre.fm stopped working in lastfmsubmitd. This version uses the library pylast to submit played songs and only submit songs to Libre.fm (hardcoded). User and password and still read from the configuration file.
