Hello.

> mode is still active on the line mode, even I press C-j.
I reported a few days ago a bug on bug.emacs list (the upper line). I have been
asked by a few persons to report it again , using the format of a bug-report
from etc/ directory.
Here it is:
1. instrument with edebug a lisp function. For example, this very simple
automaton:
(defun build-automaton (s alphabet-length first-char &optional start-pos)
"this preprocessing state builds an automaton"
(let* ((number-of-states (1+ (length s)))
(matrix (make-vector number-of-states nil))
(last-state 0))
(dotimes (i number-of-states)
(aset matrix i (make-vector alphabet-length 0))
(dotimes (j alphabet-length)
(aset (aref matrix i) j (if (and (/= i (1- number-of-states))
(equal (aref s i) (+ j first-char)))
(1+ i)
(aref (aref matrix last-state) j))))
(if (and (/= i (1- number-of-states))
(not (zerop i)))
(set 'last-state (aref (aref matrix last-state) (- (aref s i)
first-char)))))
matrix))
2. Call this function, for example like this:
(build-automaton "emacs" 27 ?a)
3. WITHOUT STOPPING the debugger kill the buffer using C-x k.
Here is the bug. The *debugging* mode is still active. More, if I want to debug
another instrumented function, impossible. We must run by hand M-: (top-level)
to come back normally to command-loop.
---------------------------------
I tried first this code in lisp/emacs-lisp/edebug.el:
(define-key map "\C-xk" (lambda ()
(interactive)
(unwind-protect (top-level)
(kill-buffer (current-buffer)))))
But this code does not work here. Can somebody explain me why, please? I do
not understant why:
Debugger entered: nil
edebug-display()
edebug(error (error "Selecting deleted buffer"))
signal(error ("Selecting deleted buffer"))
edebug-signal(error ("Selecting deleted buffer"))
----------------------
Quand j'ai eu essayé cette possibilité et vu que ça ne roule pas, il vallait le
mieux que je demande sur help.emacs list. Il y a quelqu'un qui m'a repondu. Son
code marche. Donc voici ci-dessous:
1. the output from cvs -d:pserver:address@hidden:/sources/emacs diff -c
emacs/lisp/emacs-lisp/edebug.el.
2. a Change-log-file attached.
