  [![Build Status](https://badgen.net/travis/mamantoha/mpd_client)](https://travis-ci.org/mamantoha/mpd_client)
  [![Gem Version](https://badge.fury.io/rb/mpd_client.svg)](https://badge.fury.io/rb/mpd_client)
  
  Yet another Music Player Daemon (MPD) client library written entirely in Ruby.
  `mpd_client` is a Ruby port of the [python-mpd](https://github.com/Mic92/python-mpd2) library.
  
  ## Installation
  
  Add this line to your application `Gemfile`:
  
  ```ruby
  gem 'mpd_client'
  ```
  
  And then execute:
  
  ```console
  bundle
  ```
  
  Or install it yourself as:
  
  ```console
  gem install mpd_client
  ```
  
  ## Usage
  
  All functionality is contained in the `MPD::Client` class. Creating an instance of this class is as simple as:
  
  ```ruby
  require 'mpd_client'
  
  client = MPD::Client.new
  ```
  
  Once you have an instance of the `MPD::Client` class, start by connecting to the server:
  
  ```ruby
  client.connect('localhost', 6600)
  ```
  
  or Unix domain socket
  
  ```ruby
  client.connect('/var/run/mpd/socket')
  ```
  
  The client library can be used as follows:
  
  ```ruby
  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`:
  
  ```ruby
  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.
  
  ```ruby
  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:
  
  ```ruby
  # 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:
  
  ```ruby
  # delete all songs from the current playlist, except for the firts ten
  client.delete([10,])
  ```
  
  ### Logging
  
  Default logger for all MPD::Client instances:
  
  ```ruby
  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:
  
  ```ruby
  require 'logger'
  require 'mpd_client'
  
  client = MPD::Client.new
  client.log = Logger.new($stderr)
  ```
  
  For more information about logging configuration, see [Logger](https://ruby-doc.org/stdlib-2.5.1/libdoc/logger/rdoc/Logger.html)
  
  ## Development
  
  After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
  
  To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
