Hello,
occasionally modification hooks seem to be called only once in c-mode
(and derivatives).
This happens in both released and CVS version of Emacs 22, but not in
Emacs 21.
To reproduce, evaluate the following:
(defun test-bug-hook (overlay afterp beg end &optional r)
(message "%s hook called" (if afterp "after" "before")))
(defun test-bug ()
(let ((beg (point))
ov)
(insert "foobar")
(setq ov (make-overlay beg (point)))
(overlay-put ov 'face 'highlight)
(overlay-put ov 'insert-in-front-hooks '(test-bug-hook))))
1) Create a new buffer in fundamental-mode, evaluate (test-bug), and
insert a char before the overlay.
Result:
before hook called
after hook called
1) Create a new buffer in c-mode, evaluate (test-bug), and insert a char
before the overlay.
Result:
before hook called
The hook is never called after the change.
In GNU Emacs 22.1.1 (i386-apple-darwin8.10.1, Carbon Version 1.6.0)
of 2007-07-16 on wednesday
Windowing system distributor `Apple Inc.', version 10.4.10
configured using `configure
