节点JS，使用ansi代码记录JSON [英] Node JS, logging JSON with ansi code

问题描述

我只是试图在Node.js中使用一些ANSI样式代码记录JSON，下面是代码，并带有一些示例:

I'm simply trying to log JSON with some ANSI styling codes, in Node.js, here is the code, with several examples:

let s = chalk.green('Hello World')
let o = {s} // or {s: s}

console.log(s)
console.log(o)
console.log(o.s)
console.log(JSON.stringify(o))

(注意:chalk就像colors一样)

(Note: chalk is just like colors)

但是在记录对象或对其进行字符串化时，格式会转义.有什么办法可以防止呢?
结果:

But the formatting is escaped when logging an object or stringifying it. Is there any way to prevent it?
Result:

因此，就像记录\u001b[32mHello World\u001b[39m和\\u001b[32mHello World\\u001b[39m(带有双\)一样

So it's just like logging \u001b[32mHello World\u001b[39m and \\u001b[32mHello World\\u001b[39m (with double \)

PS:我知道有数百种解决方法，但是我偶然发现了这个问题，我一直在寻找一种简单的解决方案.谢谢！

PS: I know there are hundred of workarounds but I stumbled on that problem and I've been looking for a simple solution. Thx!

推荐答案

我找到了(有点脏)修复程序:

I found a (kind of dirty) fix:

JSON.stringify(o)
  .replace(/\\/g, '')
  .replace(/u001b/g, '\u001b')

因此，如果字符串包含\u001b，则stringify将对其进行转义:\\u001b.通过替换/\\/g，它实际上仅与\相匹配，但似乎也与stringify添加的那个相匹配.
第二个replace将重新添加，只有一个且未占用空间的\.这是我到目前为止获得的最好成绩.

So if the string contains \u001b, stringify will escape it: \\u001b. By replacing /\\/g it actually matches with only \ but it seems to also the one added by stringify.
The second replace will re-add, only one and unesaped \.That's the best I got so far.
