loadCliConfig function

CliConfig loadCliConfig(String homeDir)

Loads CliConfig from ~/.fah/config.yaml.

Returns defaults when the file is missing or unreadable. A syntactically valid file whose model-roles section is invalid throws ConfigException (bad roles must surface, never silently vanish).

Implementation

CliConfig loadCliConfig(String homeDir) {
  final file = File('$homeDir/.fah/config.yaml');
  if (!file.existsSync()) return CliConfig();
  try {
    final content = file.readAsStringSync();
    final doc = loadYaml(content);
    if (doc is YamlMap) {
      final config = CliConfig.fromYaml(doc);
      _warnCanonicalizedProvider(doc, config);
      _warnDroppedGhostProviders(doc, config);
      return config;
    }
  } on ConfigException {
    rethrow;
  } on Object {
    // Ignore corrupt config and fall back to defaults.
  }
  return CliConfig();
}
