# reload_config.sh — Reload bot configuration via the admin API.
#
# Calls POST /api/admin/reload on the bot's built-in admin HTTP server.
# Equivalent to the !reload DM admin command: triggers bot.reload_config()
# in-process and returns the result immediately as JSON.
#
# Prerequisites:
#   [Admin] section in config.ini with enabled = true, port = 5001, token = <secret>
#
# Usage:
#   ./scripts/reload_config.sh                         # uses config.ini in cwd
#   ./scripts/reload_config.sh /path/to/config.ini     # explicit config path
#
# Environment overrides:
#   ADMIN_PORT   — override port  (default: read from config, fallback 5001)
#   ADMIN_TOKEN  — override token (default: read from config)
