Possible emacs bug.

Possible emacs bug.

[Charlie]

I have discovered a "feature" but I strongly suspect I am not the first.
Using emacs 21.2.1 on win32 and the version with debian woody in lisp-mode
the lisp-eval-defun (M-C-x) does not eval the defun if the indenetation is
incorrect. example:

(defun badly-indented ()
(+ 2 3))
=> 5

(defun correctly-indented ()
    (+ 2 3))
=> correctly-indented

This works in a number of inferior lisps like clisp and cmucl and in both
normal lisp mode and ilisp.
How can I find out if this has been reported and if not report it?

Cheers
Charlie.

This seems to be because of the way ``beginning-of-defun'' works. It's
looking for a "(" at the start of a line. If you want to force it to
look for "(defun" at the beginning of a line, you could do this:

(setq beginning-of-defun-function (lambda nil 
                                    (re-search-backward "^(defun")))

Cheers,

Edric.

That was easy but I couldn't have figured it out.
Thank-you.

Whee.  I think it's fine that beginning-of-defun takes some shortcuts
for indentation and movement, but maybe C-M-x should produce a more
correct result?  OTOH, then it might take very long for C-M-x to do
its thing.

All the commands that operate on on a "defun" use the same definition of
what a function definition is.  This is good for consistency, and also for
performance.

This "feature" is present in emacs 20.4 running under Unix as well.
