- local_settings_file(-LocalFile:atom) is semidet
- Breaks the module interface by asking for the current local settings file from the settings module. The local_file/1 dynamic predicate retains the path of the current local file based on loading. Loading a new settings file using load_settings/1 pushes a new local file without replacing the old one, so that the next save_settings/0 keeps saving to the original file.
- setting(:Name, ?Value, :Goal) is semidet
- Semi-deterministic version of setting/2. Succeeds only if Value
succeeds for Goal; fails otherwise. Calls Goal with Value.
Take the following example where you only want the setting predicate to succeed when it does not match the empty atom.
setting(http:public_host, A, \==(''))
