run method

@override Future<void> run()

Runs this command.

The return value is wrapped in a Future if necessary and returned by CommandRunner.runCommand.

Implementation

@override
Future<void> run() async {
  final configPath = argResults!['config'] as String;
  final file = File(configPath);
  if (!file.existsSync()) {
    stderr.writeln('Config file not found: $configPath');
    exit(1);
  }

  final yaml = loadYaml(file.readAsStringSync()) as Map;
  final config = BlueprintConfig.fromYaml(yaml);
  final targetDir = argResults!['output'] as String? ?? config.outputDir;

  await Directory(targetDir).create(recursive: true);

  final planItems = <PlanItemMessage>[];
  final bridge = EngineBridge(onMessage: (msg) {
    if (msg is PlanItemMessage) planItems.add(msg);
    if (msg is LogMessage && msg.level == 'error') {
      stderr.writeln('  error: ${msg.message}');
    }
  });

  try {
    await bridge.run(config, targetDir, dryRun: true);
  } catch (e) {
    stderr.writeln('Engine error: $e');
    exit(1);
  }

  print('\nPlanned actions for "${config.name}":');
  displayPlan(planItems);
