EMMS[fn:1] is Emacs as a multimedia player.

* Setup

Make sure you install the required packages on your system before loading the module.

#+begin_src shell
RUN apt install -y mpc mpd mpv
#+end_src

** Music player daemon
:PROPERTIES:
:header-args: :tangle ../config/mpd.conf
:END:

MPD[fn:2] uses a simple text configuration file. Most options only accept a string in " quotes ". The most important option to configure is the ~music_directory~. This is where all of the music ~mpd~[fn:2] will serve exists. It will read the directory recursively.

#+begin_src conf
music_directory  "~/.local/share/media/music"
#+end_src

You can configure where ~mpd~[fn:2] will look for playlists. You may want to configure this option if you share your playlists between devices.

#+begin_src conf
playlist_directory  "~/.local/share/media/playlists"
#+end_src

It's possible to serve ~mpd~[fn:2] over the network by configuring it to listen on =0.0.0.0=, or by the systems host name. For a local setup, leave it as =localhost=.

#+begin_src conf
bind_to_address  "localhost"
port             "6600"
#+end_src

*** Deploy the configuration

MPD[fn:2] will look for its configuration in =~/.config/mpd/mpd.conf=, and =/etc/mpd.conf= respectively.

#+begin_src emacs-lisp
(let ((mpd-dir "~/.config/mpd"))
  (unless (file-exists-p mpd-dir)
    (make-directory mpd-dir t))
  (dotfiles/symlink "~/.emacs.d/config/mpd.conf"
                    (concat mpd-dir "/mpd.conf")))
#+end_src

* Config

Displays and play multimedia from within Emacs with ~emms~[fn:1], using a variety of external players from different sources. It can run as a minimalist player and controlled with commands, or a fully fledged interactive media browser. It can display album art, play streaming media, tag files, search lyrics, and provide ~mpd~[fn:2] connectivity.

#+begin_src emacs-lisp
(use-package emms
  :custom (emms-player-mpd-server-name "localhost")
          (emms-player-mpd-server-port "6600")
  :config (require 'emms-setup)
          (require 'emms-player-mpd)
          (emms-all)
          (emms-default-players)
          (add-to-list 'emms-info-functions 'emms-info-mpd)
          (add-to-list 'emms-player-list 'emms-player-mpd))
#+end_src

* Shortcuts

Place bindings for ~emms~[fn:1] behind =SPC u=:

#+begin_src emacs-lisp
(dotfiles/leader
  "u" '(:ignore t :which-key "EMMS"))
#+end_src
