#!/usr/bin/env bash
# This i3status wrapper allows to add custom information in any position of the statusline
# It was developed for i3bar (JSON format)
# The idea is to define "holder" modules in i3status config and then replace them
# In order to make this example work you need to add
# order += "tztime holder__hey_man"
# and
# tztime holder__hey_man {
# format = "holder__hey_man"
# }
# in i3staus config
# Don't forget that i3status config should contain:
# general {
# output_format = i3bar
# }
#
# and i3 config should contain:
# bar {
# status_command exec /path/to/this/script.sh
# }
# Make sure jq is installed
# That's it
# You can easily add multiple custom modules using additional "holders"
