[cells-devel] Cells: make-kid bypasses dependencies on kids of parent ?!
I have the following definition: ;; A task is a container for ops. A task holds its ops as kids. So, when a ;;; task is called the task will call its kids. (defmd task (family) (.md-name :accessor id :initarg :id) fn-code thread state nr-ops :id (c-in (gensym "GNC.APP.TASK-")) :fn-code (c-in nil) :thread (c-in nil) :state (c-in nil) :nr-ops (c? (loop for kid in (^kids) counting (eql (type-of kid) 'op) into ops-count finally (return ops-count)))) Now, when I do
(setq self (make-instance 'task)) TASK1
(setq my-kid (make-kid 'task)) TASK 2
(^nr-ops) 0
... and this should now be 1, no ? Or what's the right way to add kids ? Thx for feedback! Best, Frank

Add them? :) make-kid does not add to the kids of self. (push (make-kid...) (kids self)) kt

Nope. I knew make-kid doesn't add kids but (fm-kid-add self my-kid) *does* add the kid. Still no luck. So I change the rule for nr-ops to :nr-ops (c? (loop for kid in (^kids) counting kid into ops-count do (trc "Counting kids" kid ops-count) finally (return ops-count))) ... and I don't get any trace output ... ??? Thx! frgo
Was a lisp image problem ... Had to restart my lisp session. Now things are working. It wasn't a cells problem ... Note: I changed the loop stuff into a simple (c? (length (^kids))) because I have to count everythÃng in there. Now a task can have a task instance as a kid. hmm - that makes a task tree or, in other words, a /program/ ! <g> Cells is just beautiful. I even don't have to see what part of the "program" has to be re-executed because the "program" or any content (= variables) have been changed... Frank

Nope. I knew make-kid doesn't add kids but
But your original report does not show you adding the instance to kids, so where you conclude nr-ops should be one I do not see why. Anyway...
(fm-kid-add self my-kid)

Is the new kids in the kids slot? Are you occasionally backtracing and not doing a cells-reset? ie, is *stop* t? kt
I dealt with something slightly related recently and simply wrote an md-awaken :after method containing (bwhen (p (^fm-parent)) (with-integrity (:change :add-to-parent) (push self (kids p)))) Worked like a charm :-) Peter On Sat, May 24, 2008 at 7:00 PM, Ken Tilton <kennytilton@optonline.net> wrote:
