rl.write(data[, key])

rl.write() 方法将 datakey 标识的按键序列写入 output。 仅当 outputTTY 文本终端时才支持 key 参数。

如果指定了 key,则忽略 data

当调用时,如果 input 流已暂停,则 rl.write() 将恢复它。

如果 readline.Interface 创建时 output 被设置为 nullundefined,则不会写入 datakey

// 模拟 Ctrl+u 删除先前写入的行。
rl.write(null, { ctrl: true, name: 'u' });

rl.write() 方法将数据写入 readlineInterfaceinput,就像它是由用户提供的一样。

The rl.write() method will write either data or a key sequence identified by key to the output. The key argument is supported only if output is a TTY text terminal.

If key is specified, data is ignored.

When called, rl.write() will resume the input stream if it has been paused.

If the readline.Interface was created with output set to null or undefined the data and key are not written.

rl.write('Delete this!');
// Simulate Ctrl+u to delete the line written previously
rl.write(null, { ctrl: true, name: 'u' });

The rl.write() method will write the data to the readline Interface's input as if it were provided by the user.
