Global regex search with "Not matching character" doesn't match newline

Issue Type: Bug

I was trying to search for

Promise\.all\(\[[^\]]*await[^\]]*\]\)

but I had no way to turn on multiline support so that ^\] would match newlines too. So searching for below would not be found.

return await Promise.all([
  await this.someFunction1(),
  await this.someFunction2(),
]);

I later put in the below and was happy to find that it suddely worked, but knew that it would only find if await was on the first line after the bracket, and also if there was no chars other than newline space or tab.

Promise\.all\(\[[^\]]*[\n\r \t]await[^\]]*\]\)

But, I then started to find others that actually SHOULDN’T have worked… It was at this point, I realsed that ^\] was working as expected the first time, and was matching on newline chars… (Perfect, I removed my tab/space hack)… To find, it stopped working again…

It seems I need atleast 1 \n in the regex to make it work.

My quick fix was to add this at the very end as such

Promise\.all\(\[[^\]]*await[^\]]*\]\)\n{0}

But this is obviously a dirty hack and not an obvious one, be far better to test for Not Matching and turn multiline back on, similar to what ever test you are doing for searching for \n and turning on multiline

I just use \n{0} a the end of all my searches… been working fine so far…

Then 👍 Big thumbs up that [^s] should indeed turn that mode on… Ok… I am up to date and agreeing. Good job everyone… take a 5 minute break and enjoy your evening.
