Using Gajim with MPD

WARNING: this page is outdated.  mpDris should be used instead of this script]

This is a simple example of what's possible with D-Bus and gajim-remote. This script reads the currently playing song out of MPD and updates the Gajim status message with gajim-remote when the song has changed.

Requirements:

• Gajim with D-Bus working (see GajimDBus)
• mpd and mpc (see  http://www.musicpd.org)

This script reads the currently playing song out of MPD and updates the Gajim Tune message when the song has changed:
