有没有办法让命令提示符（只是一个question http://nodejs.org/api/readline.html#readline_rl_question_query_callback提示符或类似的东西）固定在终端的底部，并使用它来记录其上方的输出Node.js http://nodejs.org/.

一个非常糟糕的例子：

Your favourite food is sushi.
Your favourite food is chicken.
Your favourite food is okra.
--> What is your favourite food?

所以本质上，我希望用户始终能够键入，并且输入在提示上方回显。

interface.question("What is your favourite food?", function(answer) {
    // output the answer above where this prompt was
    // and somehow keep this same prompt where is is
});

我希望在其中使用它的特定应用程序是一个简单的 IRC 客户端，其中有一个位置供用户输入，并在上面输出所有输出（用户输入的内容以及其他人也输入的内容）用户正在打字。下图中的线条是假想的。
