Description

Shows MPD status.

local mympd = 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)   |
| +-------+                                              |
+--------------------------------------------------------+

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
cover_pattern	Pattern for the album art file	string	`*\.(jpg
default_art	Default art	string	nil
notify	Show notification popups	string	"on"
followtag	Notification behaviour	boolean	false
settings	User settings	function	empty function

* In Lua, "\\" means "" escaped.

Default cover_pattern definition will made the widget set the first jpg, jpeg, png or gif file found in the directory as the album art.

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	Update widget	function
timer	The widget timer	gears.timer

The update function can be used to refresh the widget before timeout expires.

You can use timer to start/stop the widget as you like.

Keybindings

You can control the widget with keybindings like these:

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

where altkey = "Mod1".

If you don't use the widget for long periods and wish to spare CPU, you can toggle it with a keybinding like this:

-- toggle MPD widget
awful.key({ altkey }, "0",
        function ()
            local common = { text = "MPD widget ", position = "top_middle", timeout = 2 }
            if mympd.timer.started then
                mympd.timer:stop()
                common.text = common.text .. markup.bold("OFF")
            else
                mympd.timer:start()
                common.text = common.text .. markup.bold("ON")
            end
            naughty.notify(common)
        end),

Note

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