Question

我在节点REPL中设置一些细节时遇到了麻烦：

每当我在提示符中键入命令时，在从REPL获得实际输出之前，将重新打印此命令。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中的一些代码，但之后我的M-x run-js命令没有用。

这是我的初始文件（我没有编辑我的js-comint.el）：

Answer 1

如果您可以稍微改变解决问题的方法，则可以使用replpad代替。它适用于任何编辑器，只要文件发生变化就会自动更新。

只需通过以下方式安装：npm install -g replpad

然后运行：replpad

使用它

如果您希望它在当前和所有子目录中观看所有文件，并在更改时将它们传递到repl中：replpad .

Answer 2

这应该解决它：

(add-hook 'inferior-js-mode-hook
          (lambda ()
            (setq comint-process-echoes t)))
