This is a simple Spotify extension that displays the currently playing/paused song with artist, album and title. There are also some simple controls to pause/play, go to next or previous song and to exit spotify. If spotify isn't running, "Spotify is not running" is displayed together with a button to start Spotify.
To edit the text, change the string variable finalString in the script to your liking. To change the shortening threshold, change the variable maxDisplayLength to your desired length. To change the color of the Artist, Album and Title in the menu, change the variable detailColor.
This is all done using python and Mopidy, and their Spotify extension. It should be included when installing Spotify (at least I can't remember installing it separately), but should you need to install it for some reason, it can be found here. The script uses the python module psutil, install it using pip install psutil. You also need python-dbus, install it using sudo apt install python-dbus.
To easily keep up-to-date with new versions, simply make a hard link from spotifyExtension.py to your Argos folder, i.e. ln spotifyExtension.py ~/.config/argos/spotify.1l.1s.py. Then you can just git pull this repository to update.
Note: Your personal finalString, maxDisplayLength and detailColor will be overwritten when you do a git pull.
