Play/Pause Script for MPD

I've got a strange problem with which maybe someone can help me. My keyboard has a Play/Pause button, and I'd like to be able to use it as it's intended. I use MPD as my music player, and also have mpc installed. I'd like to create a simple script that determines if MPD is currently playing a song, and if it is, pause the song, and if it's not (if it's stopped or paused), then play the song.
If I can get a script that'll do that, then I can set my Play/Pause button to execute that, because "mpc play" only plays and "mpc pause" only pauses.
I'm not a programmer, and don't know any programming languages (although I used to make simple programs on my Commodore64 in Basic. That was a long time ago, though). But I can learn a few simple commands easily enough. Mostly I just need to know if anyone has any ideas on how to determine if mpd is currently playing or not. I think I can figure out the rest after that.

Never mind. I figured it out. In case anyone is curious, here's how I did it:

Code:

#!/bin/bash

for i in $(mpc --format ""); do

    a=$i

    break

done

if [$a = "[playing]"; then

    mpc pause

else

    mpc play

fi

mpc has a toggle command (at least since 0.21).

Here's the (overkill) script I made to use toggle:

Code:

#!/bin/tcsh if ($# > 0) then set SERVER="${1}" else set SERVER=localhost endif set MPC=(mpc --host="${SERVER}") ${MPC} version >& /dev/null if ($? != 0) then echo "Can't find mpd server at ${SERVER}..." exit 1 endif ${MPC} toggle # End of script #

Hi.

I use the following script to handle media keys on my laptop and bluetooth headphones via DBus:

Code:

#!/usr/bin/env python



import dbus

import dbus.service

from dbus.mainloop.glib import DBusGMainLoop

import gobject

import os



mpc = 'mpd_osd.py' # 'mpc' or 'mpd_osd.py' from http://mpd.wikia.com/wiki/Mpd_osd.py_%28using_dbus%29

def KeyHandler(x,y):

        def run(cmd):

                return lambda: os.system(mpc + ' ' + cmd)

        {

        'Play': run('toggle'),

        'Stop': run('stop'),

        'Next': run('next'),

        'Previous': run('prev')        }[y]()



DBusGMainLoop(set_as_default=True)



try:

        bus = dbus.SessionBus()

        bus_object = bus.get_object('org.gnome.SettingsDaemon',

                        '/org/gnome/SettingsDaemon/MediaKeys')

        bus_object.GrabMediaPlayerKeys("MediaKeys", 0,

                        dbus_interface='org.gnome.SettingsDaemon.MediaKeys')



        bus_object.connect_to_signal('MediaPlayerKeyPressed', KeyHandler)

except:

        print "Could not bind to Gnome for Media Keys"





loop = gobject.MainLoop()

loop.run()

Make sure this script and mpd_osd.py (if used) are somewhere in your $PATH and are executable (e.g. chmod +x media-keys.py). mpd_osd.py shows track name/artist/current status(play,pause,stop) in popup notifications.
