I need to match all .get('asfd'), but only in the case where .wait(.*) doesn't exist beforehand.

.wait(500).get('asdf') // shouldn't match
.asdf('asdf').get('asdf') // should match

Unfortunately, negative look-behinds don't support quantifiers, so I'm not sure how to describe the void between .wait( and ).get('asdf') for d*

What's the approach for matching this unquantifiable area?

I figure I need some way to describe that there wasn't a wait behind the last set of parenthesis, but is there a simple way to do that?

Thanks

Ok, it took quite a lot of experimenting, and asking this question helped to clarify the situation.

The answer is to describe the in-between: separate from the look-behind.

(?<!wait)
(?:([^)]*))
(.get(.*))

That second section allows any character until a parenthesis. Sometimes, the first parenthesis appears inside quotes, and should be ignored. Not accounting for escaped quotes, my entire regex became:

((?<!wait)(.*)s*)(.get((?:"[^"]*"|'[^']*')[^)]*))

And I use it to insert .wait() before/after .get() with match groups 1 ($1) and 2 ($2)

$1.wait(234)$2.wait(234)

I am not a regex expert, but how about this?

/^(?!.wait(d+)).*.get(.*)/g
