   4 # Description:
   5 # This hook runs `task sync` in the background at the end of each task command that mutates
   6 # the task db. The list MUTATING_COMMANDS has the list.
   7 #
   8 # Usage: simply copy this file to ~/.tasks/hooks, or whatever your hooks directory is
   9 # as specified in you taskrc file.
  10 #
  11 # Compatibility: This hook uses the Hooks V2 API (https://taskwarrior.org/docs/hooks2.html)
  12 # So, it works with TaskWarrior 2.4.3+
