Example how to use i3msg command

i3msg-jq.sh

#!/usr/bin/env bash

isWorkspaceFocused=$(i3-msg -t get_workspaces | jq 'map(select(.focused==true))|map(.num)|map(select(. == 10))|length' 2> /dev/null)
isKicktermRunning=$(i3-msg -t get_tree | jq "recurse(.nodes[]) | .window_properties | objects | .class" | grep '"Kickterm"' | wc -l 2> /dev/null)

if [ $isKicktermRunning -eq 0 ]; then
	/home/jprokop/Projects/kickterm/new-i3.py >& /dev/null
fi

if [ $isWorkspaceFocused -eq 0 ]; then
	if [ $isKicktermRunning -eq 0 ]; then
		i3-msg "workspace 10" >& /dev/null
	else
		i3-msg "[class=\"Kickterm\"] focus" >& /dev/null
	fi
else
	if [ $isKicktermRunning -ne 0 ]; then
		i3-msg "workspace 10" >& /dev/null
	fi
fi

Requires jq command as dependency.
