# i3blocks integration with dunst.

# dunst caches a notification and signals i3blocks.
# i3blocks catches the signal and prints the cached notification.
#
# Put this rule at the end of your ~/.config/dunst/dunstrc:
#
#     [i3blocks]
#         summary = "*"
#         script = FULL_PATH_OF_THIS_SCRIPT
#
# Add this block in your ~/.i3blocks.conf:
#
#     [dunst]
#     command=THIS_SCRIPT
#     signal=12

CACHE=~/.cache/i3blocks/notification
