runConfigServiceCommand function

Future<int> runConfigServiceCommand(ConfigCliCommand cmd, { required CliIO io, required ExecutionEnv env, required String? homeDir, })

Runs one fa config <verb> command and returns the process exit code.

Exit codes: 0 success; 1 the command failed (invalid config, unknown key, write refused) — the message is printed, nothing thrown, so a scripting agent always gets a clean textual answer.

Implementation

Future<int> runConfigServiceCommand(
  ConfigCliCommand cmd, {
  required CliIO io,
  required ExecutionEnv env,
  required String? homeDir,
}) async {
  final service = ConfigService(env: env, homeDir: homeDir);
  try {
    switch (cmd.verb) {
      case 'check':
        return await _check(service, io);
      case 'path':
        return await _path(service, io);
      case 'get':
        return await _get(service, io, cmd.key!);
      case 'set':
        return await _set(service, io, cmd.key!, cmd.value!, cmd.scope);
    }
  } on ConfigException catch (error) {
    io.writeln('error: ${error.message}');
    return 1;
  }
  // Unreachable: the parser admits exactly the four verbs above.
  return 1;
}
