I have the following RegEx:

val boldRegex = Regex("(?<!\\\\\\\\)@(.*)(?<!\\\\\\\\)@")

val boldRange = boldRegex.find("@test@ - this is just a test for @bold@ text")

When I run the above code in kotlin it extracts two groups with the following start/end position

0..38
5..33

What I actually need is: 0..5 and 33..38

Is there a way how to make this ungreedy (at last this is how I think it's called, I am using this website to test the RegEx: https://regex101.com/

The original RegEx in PHP looks like this: /(?<!\\\\)@(.*)(?<!\\\\)@/Us

Only by replacing `.*` with `.*?` – Wiktor Stribiżew Jan 12 '22 at 19:23
I already did that and did not help, I am still receiving indexes from exterior to the interior. @WiktorStribiżew – Marian Pavel Jan 12 '22 at 19:27

No, [it works fine](https://ideone.com/HOYCzp). I am not sure your regex will work in general though, ``"(?<!\\\\\\\\)"`` = `"""(?<!\\\\)"""` means there must be no 2 backslashes before `@`, did you mean that? – Wiktor Stribiżew Jan 12 '22 at 19:32
Yep, you're right, much appreciate, struggling to solve this for over an hour. – Marian Pavel Jan 12 '22 at 19:38
