# i3blocks integration with dunst.
# Author: Vivien Didelot <[email protected]>
#
# 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

# Ensure the cache exists
mkdir -p `dirname $CACHE`
touch $CACHE

if env | grep -q BLOCK_
then # called by i3blocks

  # clear notification on click
  test $BLOCK_BUTTON -ne 0 && cp /dev/null $CACHE

  # source the notification
  . $CACHE

  FULL_TEXT="$SUMMARY $BODY"
  SHORT_TEXT="$SUMMARY"

  case $URGENCY in

  esac

  # Output the status block
  echo $FULL_TEXT

  echo $COLOR
  exit $CODE

  # store the notification
