如何在 Windows 上的 Emacs 中以交互方式运行 node.js [英] how to run node.js interactively in Emacs on Windows

问题描述

我认为这会奏效:

(defun my-node ()
  (interactive)
  (pop-to-buffer (make-comint "my-node" "node")))

但是当我执行 M-x my-node 并在 comint 缓冲区中输入 1+1 时，它不显示任何输出.

But when I do M-x my-node and enter 1+1 in the comint buffer, it does not display any output.

这是在 Windows 7 上的 Emacs 24.0.50.1 中，无需任何特殊配置即可安装 NodeJS.

This is in Emacs 24.0.50.1 on Windows 7 and NodeJS is installed without any special configuration.

以非交互方式调用 node.js，如 M-x compile RET node hello-world.js RET 工作正常.在 cmd 中以交互方式运行 node 工作正常.

Calling node.js non-interactively as in M-x compile RET node hello-world.js RET works fine. Running node interactively in cmd works fine.

这可能是相关的:当我运行 Mx shell 并在 shell 缓冲区中输入 node 然后输入 1+1 时，它不会'不显示结果.我一定遗漏了一些非常基本的东西.

This might be related: when I run M-x shell and enter node in the shell buffer and then enter 1+1, it doesn't display the result. I must be missing something very basic.

推荐答案

我找到了一个解决方案.

I found one solution.

制作一个启动 JavaScript REPL 接口的节点脚本.

Make a node script which starts a JavaScript REPL interface.

node-in-node.js:

node-in-node.js:

var repl = require("repl");
repl.start();

将node path o ode-in-node.js"传递给 make-comint 而不是简单的node".

Pass "node path o ode-in-node.js" to make-comint instead of simply "node".

(defun my-node-shell ()
  (interactive)
  (pop-to-buffer (make-comint "Node Shell" "node" nil "C:\run\node-in-node.js")))

运行 M-x my-node-shell 在 Windows Emacs 中运行 JavaScript shell.我不知道为什么会这样.制表符补全、语法高亮、Shift+Enter 多行输入不起作用.

Run M-x my-node-shell to run a JavaScript shell in Windows Emacs. I don't know why this works. Tab completion, syntax highlight, multiline input via Shift+Enter does not work.
