Outputs current MPD playing song info (artist, album and song) plus scan the directory of the song for an album cover.

Same thing as mpd-info but it's meant to be used together with awesomewm naughty library for notification to output the info and the album cover in a popup.

How to use it

Copy mpd-popup.lua in ~/.config/awesome/ or anywhere in Lua's path. Use sudo make install from this repo's Makefile to install the c libraries in Lua's path (by default for Lua 5.2). Then add to awesomewm's rc.lua:

require("mpd-popup")

local coverart_on
local base_id = 0
function coverart_show()

	coverart_hide()

	local id, info, cover_path = mpd_main(base_id)

	if id == nil then
		return
	end
	if base_id ~= id then
		local img = image(cover_path)
		local ico = img
		local txt = info
		coverart_on = naughty.notify({
			icon = ico,
			icon_size = 80,
			text = txt,
			timeout = 3,
			position = "bottom_right",
		})
	base_id = id
	end
end

function coverart_hide()
	if coverart_on ~= nil then
		naughty.destroy(coverart_on)
	end 
end

Add a timer for the function to trigger itself (usually at the bottom but can be everywhere):

mpdtimer = timer({ timeout = 2 })
mpdtimer:add_signal("timeout", function () coverart_show() end)
mpdtimer:start()

for Awesomewm >= 3.5, change add_signal with connect_signal and use simply local img = cover_path (without image())

After that, every 2 seconds awesome will take care of triggering the function and check if the playing song in Mpd has changed; if it has, a nice naughty notification will appear with cover art and album, artist and song name. It will look for an album art in the song directory with a name containing "front" or "folder" or "albumart" or "cover" or, finally, "thumb" (in this order). The first that matches will be the one shown. If you don't see anything, be sure to have an image containing one of these words in the name.

Despite the name, there's optional support for Xmms2 daemon too. Instructions are like for MPD, only you need to use xmms-popup.lua file and build xmmsinfo.c. Substitute all "mpd" occurrences in rc.lua as shown above with "xmms", obviously.

• Libmpdclient (for MPD)
• LuaFileSystem
• Xmms2 (for Xmms2)
