Question

这关系到node.js的vorpal CLI，如下所示：

const vorpal = require('vorpal')();

用户可以使用 Ctrl - C 关闭vorpal，但是如何以编程方式关闭vorpal？

例如，如果打开了一个vorpal终端会话，但是在25秒后没有收到进一步的stdin，我想以编程方式关闭vorpal，这是我的代码的样子：

  vorpal
  .delimiter(shortCWD + chalk.magenta(' / suman>'))
  .show();

  const to = setTimeout(function () {
    vorpal.close();  // >>>  I want to programmatically close vorpal...but vorpal.close() is not a function
    process.stdin.end();
    log.error('No stdin was received after 25 seconds..closing...');
    p.killAllImmediately();
    process.exit(0);
  }, 25000);   // if no stdin has been received after 25 seconds

  process.stdin
  .setEncoding('utf8')
  .resume()
  .on('data', function customOnData(data: string) {
    clearTimeout(to);
    if (String(data) === 'q') {
      log.warning('killing all active workers.');
      p.killAllActiveWorkers();
    }
  });

虽然Vorpal没有关闭功能，但您可以使用exec或execSync以编程方式运行本机exit命令。你可能也对hide感兴趣只是隐藏了Vorpal。

<强>代码：

vorpal.exec("exit");

这怎么了？

const Vantage = require('vantage')

const v = Vantage()
    .delimiter('$test')
    .listen(9000)
    .show()

const close = () => {
    v.exec('exit', () => {
        console.log('DONE')
    })
}  
setTimeout(close, 1000)
