> applying some limited syntax highlighting using an embedded markdown
> parser. I'm only able to capture the full string, "quotes included". I

> similar desire to capture the contents of a regular expression literal
> and apply a nested regex grammar.

> I believe the javascript/typescript modes could take advantage of this

> demonstrates this.

Yuan, any comments?
