Antel MPD-Ruby

We will create a MPD widget using a MPD client written in Lua (that doesn't use mpc/netcat/telnet).

The MPD Ruby Library

Install ruby, then with rubygem install librmpd

Linux-Freebsd: gem i librmpd

MPD Widget

We want to take the output from our app, so we write this wimple widget:

function get_command_output (command)
    local c = io.popen(command)
    local output = {}
    i = 0
   return c:read("*line")
end

mympd = widget({ type = "textbox", name = "mympd", align = "left" })

Remember to add "mympd," to statusbar. To make it working, you need to call it, so you can add it to hook_timer[every second] that's included default on rc.lua or create your own:

function hook_timer ()
    mytextbox.text = " " .. os.date() .. " "
	mympd.text = " " .. get_command_output("ruby /MODIFY/YOUR/PATH/mpdr.rb") .. " "
end

Then be sure to register the hook:

[INCLUDED IN DEFAULT RC.LUA]
awful.hooks.timer.register(1, hook_timer)

Code of mpdr.rb:

#Ruby MPD wrapper

require 'rubygems'
require 'librmpd'

HOST = "localhost"
PORT = 6000

mpd = MPD.new HOST, PORT

mpd.connect
#mpd.password('mypassword')
if mpd.stopped?
    mpd.play
end
song = mpd.current_song

#Time calculation
time = mpd.status["time"]
time = time.split(':')
elapsed = time[0].to_i
el_min = elapsed / 60
el_sec = elapsed % 60
elapsed = "#{el_min}:#{el_sec}"

total = time[1].to_i
tot_min = total / 60
tot_sec = total % 60
total = "#{tot_min}:#{tot_sec}"

time = "#{elapsed}/#{total}"


#Adjusting output of Artist
artist = "#{song.artist}"
artist.gsub!(/ & /, '/')

#Adjusting output of Title
title = "#{song.title}"
title.gsub!(/_/, ' ')
title.gsub!(/ & /, '/')
title.gsub!(/feat/i, 'Ft')
title.gsub!(/remix/i, 'rmx')

#Some hacky to get correct output if id3tags are strange
if artist.empty?
    puts "[#{song.file} - #{time}]"
elsif title.empty?
    puts "[#{song.file} - #{time}]"
elsif artist =~ /artist/i
    puts "[#{song.file} - #{time}]"
elsif title =~ /track/i
    puts "[#{song.file} - #{time}]"
else
    puts "[#{artist} - #{title} - #{time}]"
end
