如何在Node REPL中编写多行代码 [英] How to write multiple lines of code in Node REPL

问题描述

我想评估

var foo = "foo";
console.log(foo);

而不是逐行评估

var foo = "foo";
undefined
console.log(foo);
foo
undefined

是否有一种简单的方法将提示移至

Is there a simple way to move the prompt to the next line?

推荐答案

节点v6.4具有编辑器模式。在repl提示符下，键入 .editor ，然后您可以输入多行。

Node v6.4 has an editor mode. At the repl prompt type .editor and you can input multiple lines.

example

$ node                                                                                                   
> .editor
// Entering editor mode (^D to finish, ^C to cancel)
const fn = there => `why hello ${there}`;
fn('multiline');
// hit ^D 
'why hello multiline'
> // 'block' gets evaluated and back in single line mode.
