Subject: track-changes and undo
Date: Sun, 21 Apr 2024 10:23:36 +0200 [thread overview]
Message-ID: <864jbvdszb.fsf@p200300d6272f17de4b8317bb694a7515.dip0.t-ipconnect.de> (raw)
Hi Stefan,
I noticed your track-changes package on ELPA the other day. Since I once (a long
time ago) wrote a package[1] that uses `before-change-functions` and
`after-change-functions` and that commits all the sins that you mention in your
package description, I thought I might try and base my package on yours.
I quickly found, though, that using your package, I was not able to distinguish
between "normal" changes and change made by undo. Currently, my code uses
`undo-in-progress` for that, but that doesn't work in the SIGNAL function passed
to `track-changes-register`, because the undo has obviously already finished
when that function is run.
So I'm wondering: is there a way to know if a change is made during undo? If
not, would it make sense to add it as an option?
TIA
Joost
BTW, feel free to answer on the list.
