#!/bin/bash
#
# This script reads webapp data (URL & Name) from the JSON file "webApps.json",
# creates webapp shortcuts in the Dock by automating Safari via AppleScript,
# and (optionally) selectively removes only those webapp items from the Dock.
#
# Requirements:
#   - macOS (with Safari)
#   - jq installed (brew install jq)
#   - Accessibility permissions granted to your terminal app for automation
#   - PlistBuddy (included in macOS)
#
# The JSON file should have the following structure:
#
# {
#   "webapps": [
#     {
#       "name": "App Name",
#       "url": "https://example.com"
#     }
#   ]
# }
#
# Usage:
#   ./setup.sh            # Creates the webapp shortcuts only.
#   ./setup.sh remove     # Creates the shortcuts and then removes the created ones.
#
