Slack Notification Count in MacOS MenuBar

#! /usr/bin/env bash

################################################################################
# This CLI tool simply outputs a small string indicating the status of your
# unread Slack notifications. It is meant to be paired with XBar to display its
# output in the MacOS MenuBar.
#
# Example output:
#   `# 0 ` => No messages at all (except perhaps in muted rooms)
#   `# 0*` => No DMs or mentions, at least one general unreads
#   `# 3 ` => 3 DMs or mentions, no general unreads
#   `# 3*` => 3 DMs or mentions, at least one general unreads
#
# Installation:
#
# 1. Ensure you have the `jq` utility installed. You can run `brew install jq`.
# 2. Ensure this script is executable: `chmod +x slack_count.1s.bash`
# 3. Install XBar and put this in its configured script directory: https://github.com/matryer/xbar

This is exactly what I have been looking for, thanks! I have used this to make a custom widget in https://github.com/Jean-Tinland/simple-bar.

Glad to hear it! They occasionally change their log location and/or json structure, so let me know if it stops working for you. But I rely on this daily, so I should notice any failures on my machine.
