It's a little tricky, though, and I'm at a loss with better variable names in some places. Wish we had some unit tests here.

For example, as you can undo or go to the previous match during the query replace, the arrow should point to the previous result, if possible. ^ permalink raw reply [flat|nested] 7+ messages in thread

Hmm, I'm not sure how to implement that. Some new hook inside perform-replace? Maybe Juri has some ideas. ^ permalink raw reply [flat|nested] 7+ messages in thread

Indeed, there is a special hook for such cases: 'replace-update-post-hook'. ^ permalink raw reply [flat|nested] 7+ messages in thread

First of all, I think (?) that we need to update the arrow's position when the replacement prompt appears, not after a replacement. Second, it fires in all cases -- whether the replacement is going forward, or it being undone, is that right? I suppose this will mean we'll need to maintain a reverse mapping: from the markers back to the Xref buffer lines. Hopefully they will be in expected position after the "undo" actions too. ^ permalink raw reply [flat|nested] 7+ messages in thread
