MPD::Client

Yet another Music Player Daemon (MPD) client library written entirely in Ruby. mpd_client is a Ruby port of the python-mpd library.

Installation

Add this line to your application Gemfile:

gem 'mpd_client'

And then execute:

bundle

Or install it yourself as:

gem install mpd_client

Usage

All functionality is contained in the MPD::Client class. Creating an instance of this class is as simple as:

require 'mpd_client'

client = MPD::Client.new

Once you have an instance of the MPD::Client class, start by connecting to the server:

client.connect('localhost', 6600)

or Unix domain socket

client.connect('/var/run/mpd/socket')

The client library can be used as follows:

puts client.mpd_version             # print the mpd version
puts client.search('title', 'ruby') # print the result of the command 'search title ruby'
client.close                        # send the close command
client.disconect                    # disconnect from the server

Command lists are also supported using command_list_ok_begin and command_list_end:

client.command_list_ok_begin # start a command list
client.update                # insert the update command into the list
client.status                # insert the status command into the list
client.command_list_end      # result will be a Array with the results

Binary responses

Some commands can return binary data.

require 'mpd_client'

client = MPD::Client.new
client.connect('localhost', 6600)

if (current_song = client.currentsong)
  data, io = client.readpicture(current_song['file'])
  io # StringIO
  data # => {"size"=>"322860", "type"=>"image/jpeg", "binary"=>"3372"}
  File.write('cover.jpg', io.string)
end

The above will locate album art for the current song and save image to cover.jpg file.

Ranges

Some commands(e.g. move, delete, load, shuffle, playlistinfo) support integer ranges([START:END]) as argument. This is done in mpd_client by using two element array:

# move the first three songs after the fifth number in the playlist
client.move([0, 3], 5)

Second element can be omitted. MPD will assumes the biggest possible number then:

# delete all songs from the current playlist, except for the firts ten
client.delete([10,])

Logging

Default logger for all MPD::Client instances:

require 'logger'
require 'mpd_client'

MPD::Client.log = Logger.new($stderr)

client = MPD::Client.new

Sets the logger used by this instance of MPD::Client:

require 'logger'
require 'mpd_client'

client = MPD::Client.new
client.log = Logger.new($stderr)

For more information about logging configuration, see Logger

Development
