[Feature Reuest] Preview regexp-replace in swiper

[seagle0128]

swiper-query-replace can start ‘query-replace’ with string to replace from last search string.
Is it possible to preview with overlays before actual doing replacement in swiper? It's really a good feature for regexp-replace. anzu does well but it's based on isearch and is unable to integrate swiper as the author clarified.

This is an example in anzu.

I don't see why it's not possible to integrate. swiper-query-replace is essentially a thin wrapper around the built-in perform-replace. Any package that improves the built-in perform-replace (with e.g. an advice), will automatically improve swiper-query-replace as well.

Hi @abo-abo The anzu package doesn't simply leverage or improve perform-replace.

Then maybe it's a good idea to make a package that does just that, and have both swiper and anzu re-use that package. Even people that don't use either might find it useful.

[seagle0128]

Yes. But I am thinking if it's possible to just port the related functionalities from anzu to swiper. Honestly I have no idea how to start.

Thanks, please test.

Thank you so much! I will test after upgrading the package.

It does work as expected. Thank you so much!
