Presently, interactive-form   called on a command that has been
adviced returns the compiled advice -- rather than the original
interactive-form

I don't understand what you mean by "returns the compiled advice".  Do you
mean it doesn't return an interactive form at all, but some piece of code
instead?  Can you give a recipe, or at least a more precise description
(e.g. sample session).

Hi Stefane,

Here is a more accurate description of the problem.

If you define an advice on a  command, and in that advice you
provide an interactive form,
then calling interactive-form later on that function ends up
returning what was created through the advice, and that turns out
to be a piece of code.

I'm hitting this because of how I end up having to advice
commands like copy-to-register -- 
whose interactive forms wouldn't provide speech feedback
otherwise.

Just defining plain advice on commands does not cause
interactive-form to lose -- things work correctly in that case.

Please give me more concrete data.  Here's what I tried:

   ELISP> (defadvice diff-refine-ignore-spaces-hunk (around sm-test activate)
            (interactive "")
            ad-do-it)
   diff-refine-ignore-spaces-hunk
   ELISP> (interactive-form 'diff-refine-ignore-spaces-hunk)
   (interactive "")
   
   ELISP> 

looks correct so far.


        Stefan

    Here is a more accurate description of the problem.

    If you define an advice on a  command, and in that advice you
    provide an interactive form,

You're aiming for the wrong goal.  It isn't a matter of "a more
accurate description".  What we need is not a _description_ -- of any
kind.  What we need is a precise test case.

Please read the Bugs section in the Emacs manual, which provides
guidelines on how to write a bug report to give us the
necessary information so we can fix the bug.

Stefane,

Here is some sample code.

If you byte compile this, then calling interactive-form on foo
will return the byte-compiled code.
;;; Define a function that uses interactive 

(defun foo (c)
(interactive "cChar:")
c)

;;; replace the interactive form via advice 

(defadvice foo (before test pre act comp)
          "Advice the interactive form."
          (interactive
(list
(progn 
(message "hello")
(read-char "Char:")))))

           
;;; (interactive-form 'foo)
;;; returns the new interactive form.

Now byte-compile this code -- you get the compiled code when you
call interactive-form.
Strictly speaking it's unclear whether this is in fact a bug. But
it would be nice if interactive-form 
did not return compiled code.

Huh?  I placed the above in a file foo.el then byte-compiled the file,
loaded it and called M-: (interactive-form 'foo) RET and got (interactive
"cChar:") in return.

Please re-read the DEBUG file explaining what is a proper way to report
a bug.  I.e. basically presume I'm a brainless idiot who barely knows what's
a keyboard and tell me *every single move* I need to do and what I'm
supposed to see after each such move.
