Subject: bug#53181: Live preview of regexp replace
Date: Tue, 11 Jan 2022 11:04:16 +0200

> It would improve the core emacs experience if the built in regexp replace
> did this as well.  When constructing a regexp replace it's really useful to
> see the match and the capturing groups instantly in the buffer, and also
> the resulting text on the fly when typing the replacement.  It spares you
> from doing several test-fix cycles until you get the regexp replacement
> right, because you have an instant live preview of everything in the target
> buffer.
