Input table

Variable	Meaning	Type	Default
timeout	Refresh timeout (in seconds)	integer	1
music_dir	Music directory	string	"~/Music"
cover_size	Album art notification size (both height and width)	integer	100
cover_pattern	Pattern for the album art file	string	`*\.(jpg
default_art	Default art	string	""
followtag	Display the notification on currently focused screen	boolean	false
settings	User settings	function	empty function
widget	Widget to render	function	wibox.widget.textbox

* 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 moc_now table, which contains the following string values:

• state (possible values: "PLAY", "PAUSE", "STOP")
• file
• artist
• title
• album
• elapsed (Time elapsed for the current track)
• total (The current track's total time)

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

moc_notification_preset = {
    title   = "Now playing",
    timeout = 6,
    text    = string.format("%s (%s) - %s\n%s", moc_now.artist,
              moc_now.album, moc_now.elapsed, moc_now.title)
}

With multiple screens, 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 widget	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 key bindings like these:

-- MOC control
awful.key({ altkey, "Control" }, "Up",
	function ()
		os.execute("mocp -G") -- toggle
		moc.update()
	end),
awful.key({ altkey, "Control" }, "Down",
	function ()
		os.execute("mocp -s") -- stop
		moc.update()
	end),
awful.key({ altkey, "Control" }, "Left",
	function ()
		os.execute("mocp -r") -- previous
		moc.update()
	end),
awful.key({ altkey, "Control" }, "Right",
	function ()
		os.execute("mocp -f") -- next
		moc.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 MOC widget
awful.key({ altkey }, "0",
        function ()
            local common = { text = "MOC widget ", position = "top_middle", timeout = 2 }
            if moc.timer.started then
                moc.timer:stop()
                common.text = common.text .. markup.bold("OFF")
            else
                moc.timer:start()
                common.text = common.text .. markup.bold("ON")
            end
            naughty.notify(common)
        end),
