It was actually a Fundamental Repair. I had overloaded the compute stack
with the responsibility of conveying dependency. Sounds reasonable until
one decides to go without dependency but of course still does not want
to get into an infinite cycle computing values. So I created a new
special variable to represent the "depender", which one could bind to
nil to avoid dependencies while still binding oneself onto the
*call-stack* to support cycle detection.
I believe (!) you changed it from setfing to
dynamically binding ...
Me? setf a special?! :)
well, all that is buried deep down there
beneath a ton of thesis work ;-)
Andy, if you could send us a more detailed description of the problem,
that might help trigger our recollection from the cells-gtk3
migration.
I think a runtime error from Cells complaining about a cycle that goes away
when reverting to older Cells would be a smoking gun. :)
As a matter of fact, that's what I had in mind.
Btw, Chris Smith got back to me concerning the doc work and we mailed
a couple times to and fro. He's now working on putting together a
good (!) getting started for cells-gtk3 and maybe smoothen out the
install process a bit. (I should apologize that I lured him over here
into the cells-gtk camp, again leaving celtk and cello without a doc.
Just as well, I haven't much time to spare these days.
Maybe one day Frank will take it on ...)
Is that algebra software coming along? I remember you talking about a
closed-user-group alpha a while ago on cll, but haven't heard anything
since. Maybe I should go back and join that yahoo group (I believe it
was).
Going good, so well I got a little greedy and went for another milestone
before releasing. Wait for an announcement, it will be a new/different
group (the name is kinda taken by other Algebra stuff). Thx for the
interest.
