Regex support -- doesn't ST2 use the Boost library?

[nick1]

As documented here, seems like this should work:

\b([a-zA-Z\-:]+)\s*=\s*(("|')?.*?(?3\s:\3))) ^^ errors out

But I’m getting an “invalid group option” error. Trying to extend the HTML syntax with attribute-value in addition to attribute-name:

Edit: More evidence that this should work. Is there a different regex parser in use between .sublime-snippet and .tmLanguage ?

Edit 2: Revised my regex a bit, seems to do the trick. Still curious about this error though.

\b([a-zA-Z\-:]+)\s*=\s*(("']?).*?(\3))

.tmLanguage files use the Oniguruma regex library, while the Find panel and snippets use boost regex.

Thanks for the reply Jon. I’ll dig into that API to see what the differences are.
