python - xmms2 track change detection for pynotify? -

-

i have written little script show current track playing on xmms2 on notification widget using xmms client , pynotify, when run can see widget popup current artist , title using xmmsclient methods.

can give hints how detect track change notify automatically without having run script manually?

you connect client library main loop, , register listener via broadcast_ playback_current_id method. if want playing id when script starts can call playback_current_id method.

here small adaptation of tutorial6 in xmms2-tutorial.git uses glib mainloop drive connection:

import xmmsclient import xmmsclient.glib import os import sys import gobject  def cb(result):     if not result.is_error():         print "current: %(artist)s - %(title)s" % result.value()   ml = gobject.mainloop(none, false)  xc = xmmsclient.xmms("stackoverflow") xc.connect()  conn = xmmsclient.glib.glibconnector(xc) xc.broadcast_playback_current_id(lambda r: xc.medialib_get_info(r.value(), cb)) ml.run()
