问题描述
我发现了突出显示预先存在的代码的语法高亮显示，但我想在你用WYSIWYG风格的编辑器输入时这样做。我不需要自动完成的功能，只需突出显示。
I've found syntax highlighters that highlight pre-existing code, but I'd like to do it as you type with a WYSIWYG-style editor. I don't need auto-completed functions, just the highlighting.
作为后续问题，stackoverflow使用的WYSIWYG编辑器是什么？
As a follow-up question, what is the WYSIWYG editor that stackoverflow uses?

推荐答案
这是一篇非常有趣的文章，关于如何编写一篇文章:(更好的是，他为JavaScript格式化程序和着色器提供了完整的源代码。）
Here is a really interesting article about how to write one: (Even better, he gives the full source to a JavaScript formatter and colorizer.)

重要的是，它正确处理正则表达式。同样令人感兴趣的是，他使用了延续传递样式词法分析器/解析器，而不是你将在野外看到的更典型的基于lex（或正则表达式）的词法分析器。
Importantly, it handles regex correctly. Also of interest is that he used a continuation passing style lexer/parser instead of the more typical lex (or regex) based lexers that you'll see in the wild.
作为奖励，他讨论了在浏览器中使用JavaScript时遇到的许多实际问题。
As a bonus he discusses a lot of real-world issues you'll run into when working with JavaScript in the browser.
