run method

@override FutureOr run()

Runs this command.

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

Implementation

@override
FutureOr run() async {
  final commands = argResults?.rest ?? [];

  if (commands.length > 1) {
    output.error('Many commands!');
    return;
  }

  if (commands.isEmpty) {
    output.error('Please, use \'slidy run --help\'');
    return;
  }
  final command = commands.first;

  final schema = argResults?['schema'] ?? 'slidy.yaml';
  final fileSchema = File(schema);

  final result = await loader(fileSchema) //
      .flatMap((pipeline) => executeScript(command, pipeline))
      .mapLeft((l) => l.message)
      .run();

  result.fold(output.error, output.success);
}
