## Inspired by Paul '@pjf' Fenwick ( https://www.youtube.com/watch?v=zl68asL9jZA )

## Keep the common agnoster.zsh-theme just as it
[…]
## Insert custom function right before Main prompt

## custom function to display the amount of overdue tasks, tasks due today, tasks due tomorrow and urgent tasks:
prompt_taskwarrior() {
  TASK="task"
  OVERDUE_COUNT=$($TASK +READY +OVERDUE count)
  DUE_TODAY_COUNT=$($TASK +READY +DUETODAY count)
  DUE_TOMORROW_COUNT=$($TASK +READY +TOMORROW count)
  URGENT_COUNT=$($TASK +READY 'urgency > 10' count)
  if [[ $OVERDUE_COUNT -gt 0 ]]; then
    prompt_segment red white "💀$OVERDUE_COUNT"
  fi
  if [[ $DUE_TODAY_COUNT -gt 0 ]]; then
    prompt_segment white blue "❢ $DUE_TODAY_COUNT"
  fi
  if [[ $DUE_TOMORROW_COUNT -gt 0 ]]; then
    prompt_segment yellow black "🗓 $DUE_TOMORROW_COUNT"
  fi
  if [[ $URGENT_COUNT -gt 0 ]]; then
    prompt_segment red white "😰 $URGENT_COUNT"
  fi
}

build_prompt() {
  RETVAL=$?
  prompt_status
  prompt_virtualenv
  prompt_context
  prompt_taskwarrior
  prompt_dir
  prompt_git
  prompt_bzr
