From: john muhl <jm <at> pub.pink> To: 71415 <at> debbugs.gnu.org Subject: bug#71415: 30.0.50; vtable-current-object off by one Date: Fri, 07 Jun 2024 09:15:07 -0500
After updating an object, ‘vtable-current-object’ in the displayer
and formatter functions points to the object after the one that
was updated. Running the following:
(with-current-buffer (get-buffer-create "vtable-demo")
(require 'vtable)
(erase-buffer)
(make-vtable
:columns '("Index" "Number")
:objects `((1 ,(random)) (2 ,(random)) (3 ,(random)))
:displayer (lambda (value &rest _)
;; vtable-current-object is off by one; e.g.
;; update the first row and v-c-o will be the second row;
;; update the final row and v-c-o will be nil.
(message "%s %s" value (vtable-current-object))
(propertize (number-to-string value) 'face 'vtable)))
(let* ((table (vtable-current-table))
(first (nth 0 (vtable-objects table)))
(other (nth 1 (vtable-objects table)))
(final (nth 2 (vtable-objects table))))
(setf (nth 1 first) 1)
(setf (nth 1 other) 2)
(setf (nth 1 final) 3)
(vtable-update-object table first)
(vtable-update-object table other)
(vtable-update-object table final)))
I see in the messages buffer:
1 (2 2) [2 times]
2 (3 3) [2 times]
3 nil [2 times]
when I expect to see:
1 (1 1) [2 times]
2 (2 2) [2 times]
3 (3 3) [2 times]
