# Prints media info from mpd, youtube, pandora
|
|
|
|
# Priority:
|
|
# 1. Prints the title of the mpd song playing, while scrolling (WORK IN PROGRESS)
|
|
# 2. Prints the title of the first open YouTube window, while scrolling (sexy!)
|
|
# NOTE: It works if the tab is in focus, so seperate the youtube tab from
|
|
# the rest of the browser so you don't have to keep it in focus and the script will work.
|
|
# 3. Prints "Pandora Radio" if there is a browser window with pandora open (same principle as above)
|
|
|
|
# Note: on tint2, set interval=0 and continuous output=2 or larger
|
|
# (in general continuous output should be larger than sleep time)
|
|
|
|
# TODO: start from the beginning if the output has changed (if the song has changed)
