javascript - Emacs中的Node REPL打印我的输入

我在节点REPL中设置一些详细信息时遇到麻烦：

每当我在提示符下键入命令时，在从REPL获得真实输出之前，都会重印此命令。例如：


  var n = 1;
  var n = 1;
  未定义


我尝试使用balajis repo https://github.com/startup-class/dotfiles/blob/master/.emacs.d/js-comint.el中的某些代码，但是之后我的M-x run-js命令不起作用。

这是我的初始化文件（我尚未编辑js-comint.el）：

最佳答案

如果可以略微改变解决问题的方法，可以使用replpad代替。它可与任何编辑器一起使用，并在文件更改时自动更新。

只需通过以下方式安装它：npm install -g replpad

然后运行以下命令来使用它：replpad

如果希望它监视当前目录和所有子目录中的所有文件，并在它们更改时将它们通过管道传递给repl，请执行以下操作：replpad .
