AwesomeWM - Spotify Widget

A simple song info and playback widget for Spotify inspired from mpd music widgets in manilaromes rice

It uses Spotify's D-Bus interface to fetch title, artist and album cover for the current song and to control playback as well.

Dependencies

It requires lua-dbus_proxy. You can use luarocks to install it:

luarocks install dbus_proxy --lua-version=5.3

Note: you must install it with the right Lua version. I use Awesome v4.3 compiled against Lua v5.3

Additional notes:

The widget needs to know if Spotify is running to connect to it's D-Bus interface. One way to do it is to constantly pgrep if Spotify is running at every interval, but that seems wasteful. So to be more efficient I made the widget to listen to "spotify::opened" signal to set up the D-Bus proxy. So we MUST emit a "spotify::opened" whenever we start spotify. You can do that either by:

• Changing the Exec in Spotify's .desktop file to also emit the signal while opening:

  - Exec=spotify
  + Exec=sh -c "path/to/my/script"

  where the script will be something like:

  #!/bin/sh
  
  spotify &
  awesome-client 'awesome.emit_signal("spotify::opened")'

• OR, add a client rule for Spotify:

  ruled.client.append_rule {
      rule = {
          class = '[Ss]potify'
      },
      callback = function(c)
          awesome.emit_signal('spotify::opened')
      end
  }
