I see Craft does support regex in replace search. But there is no info on using regex groups, ie string | replace('/this is a (string)/', 'This is another $1').
Is this feature implemented? If so - how?
Yes.
{{ 'this is a string'|replace('/this is a (string)/', 'This is another $1') }}
will output
This is another string
When you pass something that looks like a regex into the |replace filter, preg_replace() is called behind the scenes, so |replace can do anything preg_replace() can do.

Ah, thanks. I must somehow have had some typo in my code, as Craft threw an error on $1 when I tried initially. – haabe Mar 7 '17 at 20:09
