Can you actually name capture groups, or this means how you can refer to them by number?

You can use backreferences \1 \2 etc. but you can also give them names explicitly.
it looks like this: (?<name>inner-regex)
Some flavors support it, kotlins doesn’t apparently.

TIL thanks!

Named groups are nice but can I please define a group more than once because maybe I want to group my data and consolidate values in a logical way without you complaining I have already used a group previously. I know I did, I’m the one telling you, now capture it twice!

I really like this approach for doing non trivial regex https://github.com/VerbalExpressions

const tester = VerEx()
    .startOfLine()
    .then('http')
    .maybe('s')
    .then('://')
    .maybe('www.')
    .anythingBut(' ')
    .endOfLine();
