NAME

       Audio::MPD - class to talk to MPD (Music Player Daemon) servers

VERSION

       version 2.004

SYNOPSIS

           use Audio::MPD;

           my $mpd = Audio::MPD->new;
           $mpd->play;
           sleep 10;
           $mpd->next;

DESCRIPTION

       Audio::MPD gives a clear object-oriented interface for talking to and controlling MPD
       (Music Player Daemon) servers. A connection to the MPD server is established as soon as a
       new Audio::MPD object is created.

       Since mpd is still in 0.x versions, Audio::MPD sticks to latest mpd (0.15 as time of
       writing) protocol & behaviour, and does not try to maintain backward compatibility.

       Note that the module will by default connect to mpd before sending any command, and will
       disconnect after the command has been issued. This scheme is far from optimal, but allows
       us not to care about timeout disconnections. Because of that, the "idle" command (new in
       mpd 0.14) is not (and will not) be supported in Audio::MPD. This will be implemented in
       POE::Component::Client::MPD.

       /!\ Note that Audio::MPD is using high-level, blocking sockets.  This means that if the
       mpd server is slow, or hangs for whatever reason, or even crash abruptly, the program will
       be hung forever in this sub.  The POE::Component::Client::MPD module is way safer - you're
       advised to use it instead of Audio::MPD. Or you can try to set "conntype" to $REUSE (see
       Audio::MPD constructor for more details), but you would be then on your own to deal with
       disconnections.

   Searching the collection
       To search the collection, use the "collection()" accessor, returning the associated
       Audio::MPD::Collection object. You will then be able to call:

           $mpd->collection->all_songs;

       See Audio::MPD::Collection documentation for more details on available methods.

   Handling the playlist
       To update the playlist, use the "playlist()" accessor, returning the associated
       Audio::MPD::Playlist object. You will then be able to call:

           $mpd->playlist->clear;

       See Audio::MPD::Playlist documentation for more details on available methods.

ATTRIBUTES

   host
       The hostname where MPD is running. Defaults to environment var "MPD_HOST", then to
       'localhost'. Note that "MPD_HOST" can be of the form "password@host:port" (each of
       "password@" or ":port" can be omitted).

   port
       The port that MPD server listens to. Defaults to environment var "MPD_PORT", then to
       parsed "MPD_HOST" (cf above), then to 6600.

   password
       The password to access special MPD functions. Defaults to environment var "MPD_PASSWORD",
       then to parsed "MPD_HOST" (cf above), then to empty string.

   conntype
       Change how the connection to mpd server is handled. It should be of a "CONNTYPE" type (cf
       Audio::MPD::Types). Use either the "reuse" string to reuse the same connection or "once"
       to open a new connection per command (default).

METHODS

   new
           my $mpd = Audio::MPD->new( \%opts );

       This is the constructor for Audio::MPD. One can specify any of the attributes (cf above).

CONTROLLING THE SERVER

   ping
           $mpd->ping;

       Sends a ping command to the mpd server.

   version
           my $version = $mpd->version;

       Return mpd's version number as advertised during connection. Note that mpd returns
       protocol version when connected. This protocol version can differ from the real mpd
       version. eg, mpd version 0.13.2 is "speaking" and thus advertising version 0.13.0.

   kill
           $mpd->kill;

       Send a message to the MPD server telling it to shut down.

   set_password
           $mpd->set_password( [$password] );

       Change password used to communicate with MPD server to $password.  Empty string is assumed
       if $password is not supplied.

   updatedb
           $mpd->updatedb( [$path] );

       Force mpd to recan its collection. If $path (relative to MPD's music directory) is
       supplied, MPD will only scan it - otherwise, MPD will rescan its whole collection.

   urlhandlers
           my @handlers = $mpd->urlhandlers;

       Return an array of supported URL schemes.

HANDLING VOLUME & OUTPUT

   volume
           $mpd->volume( [+][-]$volume );

       Sets the audio output volume percentage to absolute $volume.  If $volume is prefixed by
       '+' or '-' then the volume is changed relatively by that value.

   outputs
           my @outputs = $mpd->outputs( );

       Return a list of "Audio::MPD::Common::Outputs" with all outputs available within MPD.

   output_enable
           $mpd->output_enable( $output );

       Enable the specified audio output. $output is the ID of the audio output.

   output_disable
           $mpd->output_disable( $output );

       Disable the specified audio output. $output is the ID of the audio output.

RETRIEVING INFO FROM CURRENT STATE

   stats
           my $stats = $mpd->stats;

       Return an Audio::MPD::Common::Stats object with the current statistics of MPD. See the
       associated pod for more information.

   status
           my $status = $mpd->status;

       Return an Audio::MPD::Common::Status object with various information on current MPD server
       settings. See the associated pod for more information.

   current
           my $song = $mpd->current;

       Return an Audio::MPD::Common::Item::Song representing the song currently playing.

   song
           my $song = $mpd->song( [$song] );

       Return an Audio::MPD::Common::Item::Song representing the song number $song. If $song is
       not supplied, returns the current song.

   songid
           my $song = $mpd->songid( [$songid] );

       Return an Audio::MPD::Common::Item::Song representing the song with id $songid. If $songid
       is not supplied, returns the current song.

ALTERING MPD SETTINGS

   repeat
           $mpd->repeat( [$repeat] );

       Set the repeat mode to $repeat (1 or 0). If $repeat is not specified then the repeat mode
       is toggled.

   random
           $mpd->random( [$random] );

       Set the random mode to $random (1 or 0). If $random is not specified then the random mode
       is toggled.

   fade
           $mpd->fade( [$seconds] );

       Enable crossfading and set the duration of crossfade between songs.  If $seconds is not
       specified or $seconds is 0, then crossfading is disabled.

CONTROLLING PLAYBACK

   play
           $mpd->play( [$song] );

       Begin playing playlist at song number $song. If no argument supplied, resume playing.

   playid
           $mpd->playid( [$songid] );

       Begin playing playlist at song ID $songid. If no argument supplied, resume playing.

   pause
           $mpd->pause( [$state] );

       Pause playback. If $state is 0 then the current track is unpaused, if $state is 1 then the
       current track is paused.

       Note that if $state is not given, pause state will be toggled.

   stop
           $mpd->stop;

       Stop playback.

   next
           $mpd->next;

       Play next song in playlist.

   prev
           $mpd->prev;

       Play previous song in playlist.

   seek
           $mpd->seek( $time, [$song]);

       Seek to $time seconds in song number $song. If $song number is not specified then the perl
       module will try and seek to $time in the current song.

   seekid
           $mpd->seekid( $time, $songid );

       Seek to $time seconds in song ID $songid. If $song number is not specified then the perl
       module will try and seek to $time in the current song.
