Implementation

@override
Future<void> handle(List<String> args) async {
  final projectName = argResults?['name'] as String?;
  if (projectName == null) {
    logger.error('Usage: khadem new --name=<project_name>');
    exitCode = 1;
    return;
  }

  final targetPath =
      Directory.current.path + Platform.pathSeparator + projectName;

  // Check if target directory already exists
  if (Directory(targetPath).existsSync()) {
    logger.error('❌ Directory "$projectName" already exists');
    exitCode = 1;
    return;
  }

  logger.info('📁 Creating new project: $projectName');
  logger.info('📥 Cloning template from GitHub...');

  try {
    // Clone the template repository
    await _cloneTemplate(targetPath);

    // Clean up git directory
    await _cleanupGitDirectory(targetPath);

    // Remove template license file (projects should provide their own)
    await _cleanupLicenseFiles(targetPath);

    // Replace placeholders in files
    await _replaceProjectPlaceholders(Directory(targetPath), projectName);

    // Update .env file
    await _updateEnvFile(targetPath, projectName);

    logger.info('✅ Project "$projectName" created successfully!');
    logger.info('👉 Next: cd $projectName && dart pub get');
    exitCode = 0;
