NAME Net::MPD - Communicate with an MPD server SYNOPSIS use Net::MPD; my $mpd = Net::MPD->connect(); $mpd->stop(); $mpd->clear(); $mpd->search_add(Artist => 'David Bowie'); $mpd->shuffle(); $mpd->play(); $mpd->next(); while (1) { my @changes = $mpd->idle(); print 'Changed: ' . join(', ', @changes) . "\n"; } DESCRIPTION Net::MPD is designed as a lightweight replacment for Audio::MPD which depends on Moose and is no longer maintained. METHODS connect [$address] Connect to the MPD running at the given address. Address takes the form of password@host:port. Both the password and port are optional. If no password is given, none will be used. If no port is given, the default (6600) will be used. If no host is given, "localhost" will be used. Return a Net::MPD object on success and croaks on failure. version Return the API version of the connected MPD server. update_status Issue a "status" command to MPD and stores the results in the local object. The results are also returned as a hashref. MPD ATTRIBUTES Most of the "status" attributes have been written as combined getter/setter methods. Calling the "update_status" method will update these values. Only the items marked with an asterisk are writable. volume* repeat* random* single* consume* playlist playlist_length state song song_id next_song next_song_id time elapsed bitrate crossfade* mix_ramp_db* mix_ramp_delay* audio updating_db error replay_gain_mode* MPD COMMANDS The commands are mostly the same as the MPD protocol <http://www.musicpd.org/doc/protocol/index.html> but some have been renamed slightly. clear_error Clear the current error message in status. This can also be done by issuing any command that starts playback. current_song Return the song info for the current song. idle [@subsystems] Block until a noteworth change in one or more of MPD's subsystems. As soon as there is one, a list of all changed subsystems will be returned. If any subsystems are given as arguments, only those subsystems will be monitored. The following subsystems are available: database The song database has been changed after an update. udpate A database update has started or finished. stored_playlist A stored playlist has been modified. playlist The current playlist has been modified. player Playback has been started stopped or seeked. mixer The volume has been adjusted. output An audio output has been enabled or disabled. sticker The sticket database has been modified. subscription A client has subscribed or unsubscribed from a channel. message A message was received on a channel this client is watching. stats Return a hashref with some stats about the database. next Play the next song in the playlist. pause $state Set the pause state. Use 0 for playing and 1 for paused. play [$position] Start playback (optionally at the given position). play_id [$id] Start playback (optionally with the given song). previous Play the previous song in the playlist. seek $position $time Seek to $time seconds in the given song position. seek_id $id $time Seek to $time seconds in the given song. seek_cur $time Seek to $time seconds in the current song. stop Stop playing. add $path Add the file (or directory, recursively) at $path to the current playlist. add_id $path [$position] Add the file at $path (optionally at $position) to the playlist and return the id. clear Clear the current playlist. delete $position Remove the song(s) in the given position from the current playlist. delete_id $id Remove the song with the given id from the current playlist. move $from $to Move the song from position $from to $to. move_id $id $to Move the song with the given id to position $to. playlist_find $tag $search Search the current playlist for songs with $tag exactly matching $search. playlist_id $id Return song information for the song with the given id. playlist_info [$position] Return song information for every song in the current playlist (or optionally the one at the given position). playlist_search $tag $search Search the current playlist for songs with $tag partially matching $search. playlist_changes $version Return song information for songs changed since the given version of the current playlist. playlist_changes_pos_id $version Return position and id information for songs changed since the given version of the current playlist. prio $priority $position Set the priority of the song at the given position. prio_id $priority $id Set the priority of the song with the given id. shuffle Shuffle the current playlist. swap $pos1 $pos2 Swap the positions of the songs at the given positions. swapid $id1 $id2 Swap the positions of the songs with the given ids. list_playlist $name Return a list of all the songs in the named playlist. list_playlist_info $name Return all the song information for the named playlist. list_playlists Return a list of the stored playlists. load $name Add the named playlist to the current playlist. playlist_add $name $path Add the given path to the named playlist. playlist_clear $name Clear the named playlist. playlist_delete $name $position Remove the song at the given position from the named playlist. playlist_move $name $id $pos Move the song with the given id to the given position in the named playlist. rename $name $new_name Rename the named playlist to $new_name. rm $name Delete the named playlist. save $name Save the current playlist with the given name. count $tag $search ... Return a count and playtime for all items with $tag exactly matching $search. Multiple pairs of $tag/$search parameters can be given. find $tag $search ... Return song information for all items with $tag exactly matching $search. The special tag 'any' can be used to search all tag. The special tag 'file' can be used to search by path. find_add $tag $search Search as with "find" and add any matches to the current playlist. list $tag [$artist] Return all the values for the given tag. If the tag is 'album', an artist can optionally be given to further limit the results. list_all [$path] Return a list of all the songs and directories (optionally under $path). list_all_info [$path] Return a list of all the songs as with "listall" but include metadata. search $tag $search ... As "find" but with partial, case-insensitive searching. search_add $tag $search ... As "search" but adds the results to the current playlist. search_add_pl $name $tag $search ... As "search" but adds the results the named playlist. update [$path] Update the database (optionally under $path) and return a job id. rescan [$path] As <update> but forces rescan of unmodified files. sticker_value $type $path $name [$value] Return the sticker value for the given item after optionally setting it to $value. Use an undefined value to delete the sticker. sticker_list $type $path Return a hashref of the stickers for the given item. sticker_find $type $name [$path] Return a list of all the items (optionally under $path) with a sticker of the given name. close Close the connection. This is pretty worthless as the library will just reconnect for the next command. kill Kill the MPD server. ping Do nothing. This can be used to keep an idle connection open. If you want to wait for noteworthy events, the "idle" command is better suited. disable_output $id Disable the given output. enable_output $id Enable the given output. outputs Return a list of the available outputs. commands Return a list of the available commands. not_commands Return a list of the unavailable commands. tag_types Return a list of all the avalable song metadata. url_handlers Return a list of available url handlers. decoders Return a list of available decoder plugins, along with the MIME types and file extensions associated with them. subscribe $channel Subscribe to the named channel. unsubscribe $channel Unsubscribe from the named channel. channels Return a list of the channels with active clients. read_messages Return a list of any available messages for this clients subscribed channels. send_message $channel $message Send a message to the given channel. TODO Command Lists MPD supports sending batches of commands but that is not yet available with this API. Asynchronous IO Event-based handling of the idle command would make this module more robust. BUGS Idle connections MPD will close the connection if left idle for too long. This module will reconnect if it senses that this has occurred, but the first call after a disconnect will fail and have to be retried. Calling the "ping" command periodically will keep the connection open if you do not have any real commands to issue. Calling the "idle" command will block until something interesting happens.
