Hack:Mpc-play

From Music Player Daemon Community Wiki

This simple perl-script allow you to use mpc as general-purpose player like xmms (i.e. to play any file, even if it is outside mpdroot directory).

Here's a little python script that does essentialy the same, just hacked up because I didn't like some small things about the perl version and I'm not comfortable writing perl. :-)

#!/usr/bin/env python
import os, sys

mpd_root = '/home/jan/snd'
tmp_dir = 'tmp'

if not len(sys.argv) > 1:
    print >>sys.stderr, 'Usage:\n%s <files>' % sys.argv[0]
    sys.exit(1)

def still_updating():
    return 'Updating DB' in os.popen('mpc').read()

links = []
for file in sys.argv[1:]:
    linkname = '%s/%s' % (tmp_dir, os.path.basename(file))
    os.symlink(file, '%s/%s' % (mpd_root, linkname))
    links.append(linkname)

os.system('mpc update %s >/dev/null' % tmp_dir)

while still_updating(): pass

for link in links:
    os.system('mpc add "%s"' % link)
