mpd

Shows MPD status in a textbox.

mpdwidget = lain.widgets.mpd()

Now playing songs are notified like this:

+--------------------------------------------------------+
| +-------+                                              |
| |/^\_/^\| Now playing                                  |
| |\ O O /| Cannibal Corpse (Hammer Smashed Face) - 1993 |
| | '.o.' | Hammer Smashed Face (Radio Disney Version)   |
| +-------+                                              |
+--------------------------------------------------------+

You need a file like this

(Front|front|Cover|cover|Art|art|Folder|folder)\.(jpg|jpeg|png|gif)

in the album folder in order to show album art too.

Note: if MPD is turned off or not set correctly, the widget will constantly display "N/A" values.

Input table

Variable	Meaning	Type	Default
timeout	Refresh timeout seconds	int	2
password	MPD password	string	""
host	MPD server	string	"127.0.0.1"
port	MPD port	string	"6600"
music_dir	Music directory	string	"~/Music"
cover_size	Album art notification size	int	100
default_art	Default art	string	""
notify	Show notification popups	string	"on"
followtag	Notification behaviour	boolean	false
echo_cmd	custom call for echo*	string	"echo"
settings	User settings	function	empty function

* echo implementation is shell dependent, you may need to set this variable properly (echo -e for instance) in order for the widget to fetch the data correctly.

Pay attention to case sensitivity when defining music_dir.

settings can use mpd_now table, which contains the following values:

(note: the first four are boolean flags, the remaining are all strings)

• random_mode
• single_mode
• repeat_mode
• consume_mode
• pls_pos (playlist position)
• pls_len (playlist length)
• state (possible values: "play", "pause", "stop")
• file
• artist
• title
• name
• album
• track
• genre
• date
• time (length of current song, in seconds)
• elapsed (elapsed time of current song, in seconds)

and can modify mpd_notification_preset table, which will be the preset for the naughty notifications. Check here for the list of variables it can contain. Default definition:

mpd_notification_preset = {
   title   = "Now playing",
   timeout = 6,
   text    = string.format("%s (%s) - %s\n%s", mpd_now.artist,
             mpd_now.album, mpd_now.date, mpd_now.title)
}

In multiple screen setups, the default behaviour is to show a visual notification pop-up window on the first screen. By setting followtag to true it will be shown on the currently focused tag screen.

Output table

Variable	Meaning	Type
widget	The textbox	wibox.widget.textbox
update	The notification	function

You can control the widget with key bindings like these:

-- MPD control
awful.key({ altkey, "Control" }, "Up",
	function ()
		awful.spawn_with_shell("mpc toggle || ncmpcpp toggle || ncmpc toggle || pms toggle")
		mpdwidget.update()
	end),
awful.key({ altkey, "Control" }, "Down",
	function ()
		awful.spawn_with_shell("mpc stop || ncmpcpp stop || ncmpc stop || pms stop")
		mpdwidget.update()
	end),
awful.key({ altkey, "Control" }, "Left",
	function ()
		awful.spawn_with_shell("mpc prev || ncmpcpp prev || ncmpc prev || pms prev")
		mpdwidget.update()
	end),
awful.key({ altkey, "Control" }, "Right",
	function ()
		awful.spawn_with_shell("mpc next || ncmpcpp next || ncmpc next || pms next")
		mpdwidget.update()
	end),

where altkey = "Mod1".

Notes

• In settings, if you use widget:set_text, it will ignore Pango markup, so be sure to always use widget:set_markup.
