One thing I like about Emacs a lot is that it remembers the undo/redo
states across saves. I think that saving should not wipe out the undo
possibilities. Didn't Photoshop go back to single undo? I think they
replaced multiple undo with a sort of editable history log. I think
that would be even better than multiple undo.

I know that the Ableton programmers have joked about the challenges
of designing their endless undo system. I am guessing that it relies
upon keeping track of every change between state saves, since they
also have a nifty feature that will rescue unsaved changes if the
system crashes for some reason. This is stored in a temporary file
location specified in the preferences menu of the program.So basically the multiple undo system would have to keep a running
log in some temporary file, documenting each state change in the
software. Beyond me, but I agree that this feature is much-desired!~Kyle

would that be difficult?When I originally harassed Miller so that he implements undo, I
thought he'd go for multiple undo. Instead, he went for single.
Basically there's not much more you have to do to get multiple undo
if the single undo was done "right", but that means "if the single
undo has been implemented with a future multiple undo in mind". The
undo-system is one of the rare parts of pd source-code that I
haven't read, because I wanted to reimplement it from scratch
anyway. So I can't really tell you right away whether Miller's
system could be adapted or not.My own multiple-undo code doesn't really work well, but that's not
because it's multiple, it's because it's implemented in the client
instead, and there were too many things that had to be changed in
the server to get that working, and I have other excuses as well ;)_ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal, Québec _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
