NAME ^

Audio::XMMSClient - Interface to the xmms2 music player

SYNOPSIS ^

  use Audio::XMMSClient;

  my $conn = Audio::XMMSClient->new($client_name);
  $conn->connect or die $c->get_last_error;

  my $result = $c->playback_status;
  $result->wait;
  print $result->value;

DESCRIPTION ^

This module provides a perl interface to the xmms2 client library.

METHODS ^

new

Arguments: $client_name?
Return Value: $connection
  my $conn = Audio::XMMSClient->new('foo');

Creates a new Audio::XMMSClient instance. If $client_name is omitted it will use the name of your application (see $0/$PROGRAM_NAME in perlvar).

connect

Arguments: $ipcpath?
Return Value: $success
  my $success = $conn->connect;

Tries to establish a connection to the xmms2 server. If $ipcpath is omitted it will fall back to $ENV{XMMS_PATH} and, if that's unset as well, the default ipcpath of libxmmsclient. If an error occurs a false value is returned and a message describing the error can be obtained using "get_last_error".

disconnect_callback_set

Arguments: \&func, $data?
Return Value: none
  $conn->disconnect_callback_set(sub { die 'got disconnected' });

Registers a function which will be called if the connection to the xmms2 server gets abnormally terminated. \&func will be called with either one or two arguments. The first one will be a reference to the connection. $data, if passed, will be the second argument of the callback.

io_disconnect

Arguments: none
Return Value: none
  $conn->io_disconnect;

Flags the connection as disconected. This is to be called when the mainloop signals disconnection of the connection. This is optional, any call to "io_out_handle" or "io_in_handle" will notice the disconnection and handle it accordingly.

get_last_error

Arguments: none
Return Value: $error_message
  my $message = $conn->get_last_error;

Returns a string that descibes the last error (if any).

plugin_list

Arguments: $type?
Return Value: $result
  my $result = $conn->plugin_list;

Get a list of loaded plugins from the server. $type, which may be used to only get a list of plugins of a specific type, can be any of the following strings:

If $type is omitted "all" is assumed.

main_stats

Arguments: none
Return Value: $result
  my $result = $conn->main_stats;

Get a list of statistics from the server.

quit

Arguments: none
Return Value: $result
  my $result = $conn->quit;

Tell the server to quit. This will terminate the server. If you only want to disconnect just destroy all references to the connection instance.

broadcast_quit

Arguments: none
Return Value: $result
  my $result = $conn->broadcast_quit;

Request the quit broadcast. Will be called when the server is terminating.

medialib_get_id

Arguments: $url
Return Value: $result
  my $result = $conn->medialib_get_id('file:///home/user/music/artist/album/track.flac');

Search for a entry (URL) in the medialib db and return its ID number.

medialib_remove_entry

Arguments: $entry
Return Value: $result
  my $result = $conn->medialib_remove_entry(1337);

Remove a entry with a given ID from the medialib.

medialib_add_entry

Arguments: $url
Return Value: $result

Arguments: $url, @args?
Return Value: $result
  my $result = $conn->medialib_add_entry_args(
          "file:///data/HVSC/C64Music/Hubbard_Rob/Commando.sid",
          "subtune=2",
  );

Add a $url with arguments to the medialib.

medialib_add_entry_encoded

Arguments: $url
Return Value: $result
  my $result = $conn->medialib_add_entry_encoded($url);

Same as "medialib_add_entry", except it expects an encoded $url.

playlist

Arguments: $playlist_name?
Return Value: $playlist
  my $playlist = $conn->playlist('jrock');

Returns an Audio::XMMSClient::Playlist instance representing a playlist specified by $playlist_name. If no $playlist_name is given "_active" will be used.

medialib_path_import
