* MPD
As its name indicates, the [[https://www.musicpd.org/][Music Player Daemon]] --- or MPD for short
--- is a daemon that manages music files on a computer and plays them.
It can be manipulated by various front-end applications, such as the
command-line utility ~mpc~, TUI ~ncmpcpp~, or GUI ~cantata~. In my case, I
use mainly ~ncmpcpp~ and Emacs EMMS.
On my computer, MPD runs as a user daemon.
** Required Parameters
MPD requires a few compulsory parameters that we will see below.
#+name: mpd-required-parameters
| Parameter name | Value | Comment |
|-------------------------+---------------------------+--------------------------------------------------------------------------|
| =follow_outside_symlinks= | =yes= | Whether to follow symlinks pointing outside the music directory |
| =follow_inside_symlinks= | =yes= | Whether to follow symlinks pointing inside the music directory |
| =db_file= | =~/.config/mpd/database= | Location of MPDs database |
| =sticker_file= | =~/.config/mpd/sticker.sql= | Location of the sticker database (dynamic information attached to songs) |
| =log_file= | =~/.config/mpd/log= | Location of MPDs log file |
#+name: mpd-gen-values
#+begin_src emacs-lisp :var table=mpd-required-parameters :exports results
(mapconcat (lambda (parameter)
(let* ((trim-name (lambda (parameter)
(replace-regexp-in-string (regexp-quote "=")
""
parameter)))
(name (apply trim-name `(,(car parameter))))
(value (apply trim-name `(,(cadr parameter)))))
(format "%s \"%s\"" name value)))
table
"\n")
#+end_src
#+RESULTS: mpd-gen-values
#+begin_src conf-space
follow_outside_symlinks "yes"
follow_inside_symlinks "yes"
db_file "~/.config/mpd/database"
sticker_file "~/.config/mpd/sticker.sql"
log_file "~/.config/mpd/log"
#+end_src
** Optional Parameters
While these values are not strictly necessary, some are still useful
such as ~music_directory~: we dont have to manually add our music to
MPD each time we run it.
#+name: mpd-optional-parameters
| Parameter | Value | Comment |
|--------------------+---------------------+-----------------------------------------------------------|
| =music_directory= | =~/Music= | Location of the music directory |
| =playlist_directory= | =~/Music/playlists= | Location of MPD playlists |
| =pid_file= | =~/.config/mpd/pid= | Location of MPDs PID |
| =state_file= | =~/.config/mpd/state= | File where the state of MPD is saved when killed |
| =bind_to_address= | =localhost= | Limit MPD to the localhost address |
| =auto_update= | =yes= | No need to manually update MPDs database with ~mpc update~ |

#+end_src
** Audio outputs
Two audio outputs will be defined. The first one sets Pulseaudio up,
so I can actually hear my music. Its configuration is simple, really.
#+begin_src conf-space
audio_output {
type "pulse"
name "pulse audio"
}
#+end_src
Another one sets up the visualizer of ~ncmpcpp~. It is not necessary to
create this one if you dont plan on using this feature.
#+begin_src conf-space
audio_output {
type "fifo"
name "my_fifo"
path "/tmp/mpd.fifo"
format "44100:16:2"
}
#+end_src
