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

[-] VegOwOtenks@lemmy.world 25 points 4 months ago

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.

In modern languages you can name them with labels as well yes. Not sure about the syntax right now. Something like (?label:...) I think

It's (?<NAME>...) and those are the named capture groups referred to in the post.
