moc

A widget for showing the current song track's information from MOC (Music On Console).

It also provides next track notifications using Naughty.

mocwidget = lain.widgets.contrib.moc()

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.

Input table

Variable	Meaning	Type	Default
timeout	Refresh timeout seconds	int	1
music_dir	Music directory	string	"~/Music"
cover_size	Album art notification size	int	100
default_art	Default art	string	""
followtag	Display the notification on currently focused screen	boolean	false
settings	User settings	function	empty function

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)
}

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 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 ()
		awful.spawn.with_shell("mocp -G")
		mocwidget.update()
	end),
awful.key({ altkey, "Control" }, "Down",
	function ()
		awful.spawn.with_shell("mocp -s")
		mocwidget.update()
	end),
awful.key({ altkey, "Control" }, "Left",
	function ()
		awful.spawn.with_shell("mocp -r")
		mocwidget.update()
	end),
awful.key({ altkey, "Control" }, "Right",
	function ()
		awful.spawn.with_shell("mocp -f")
		mocwidget.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 mocwidget.timer.started then
                mocwidget.timer:stop()
                common.text = common.text .. markup.bold("ON")
            else
                mocwidget.timer:start()
                common.text = common.text .. markup.bold("OFF")
            end
            naughty.notify(common)
        end),
