Instance Method Details

#value(key, env_only = false) ⇒ Object

Fetch a config value. It first attempts to fetch an ENV var prefixed with ‘SCOUT_’, then from the settings file.

If you set env_only, then it will not attempt to read the config file at all, and only read off the ENV var this is useful to break a loop during boot, where we needed an option to set the application root.
