FR: Event `front_app_switched` should also send deactivated app

[FelixKratz]

The way I would keep track of the previously focussed app in sketchybar would not be different from a scripting approach:
when the front app changes, write the current front app to some cache and use it on the next event to retrieve the previously focused window.

For example use this handle script for the front_app_switched event:

#!/bin/bash

if [ "$SENDER" = "front_app_switched" ]; then
  PREVIOUS_FRONT_APP=$(</tmp/front_app)
  echo "$INFO" > /tmp/front_app

  sketchybar --set $NAME label="$INFO" icon.background.image="app.$INFO"
fi

Ah, yeah, that works as well. For reference if anyone finds this issue:

# only trigger on deactivation of $TASK_APP
if [[ "$SENDER" = "front_app_switched" ]]; then
	data="/tmp/sketchybar_front_app"
	[[ -f "$data" ]] && deactivated_app=$(<"$data")
	echo -n "$INFO" >"$data"
	[[ "$deactivated_app" != "$TASK_APP" ]] && return 0
fi
