Hello
While in GNU emacs define-minor-mode *does* add an entry into the
modeline, it *does not* for XEmacs (21.4.x mule or nomule).
The only way I see it is to write an ugly kludge who adds explicitly
that entry. Does anybody know about a better solution?
Thanks

it *should* add it to the modeline. this is accomplished using
add-minor-mode, which is called by define-minor-mode. it's possible
that, if you're dynamically changing things, you won't see the change
till you delete a buffer and revisit it.

Ha I was about to tell you that it does not and it is a bug, however
xemacs -vanilla told me different. So I have to check my packages in
order to find the incompatibility.

So I did some testing, not finished yet, there are incompatibilities
with longlines.el which uses define-minor-mode and older pkg such as
appt.el. (I still don't know why). Before I proceed a important
question what is the advantage of using define-minor-mode over the
*old* way of defining a minor mode?

If you know exactly what you're doing, none. However, there are a
number of conventions that you're supposed to follow in initializing a
minor mode, and define-minor-mode ensures that.
The problem is probably that XEmacs's version is not fully synched to
GNU Emacs's.

That is my impression as well. Let us see
this is the gnus definition
(define-minor-mode longlines-mode
nil " ll" nil
(if longlines-mode
;; Turn on longlines mode
(progn
(add-to-list 'buffer-file-format 'longlines)
CODE)
;; Turn off longlines mode
(setq buffer-file-format (delete 'longlines buffer-file-format))
MORE CODE))
I rewrote that as following
;;{{{ real minor mode
(defvar longlines-mode nil
"Determines if mylonglines minor mode is active.")
(make-variable-buffer-local 'longlines-mode)
(defun longlines-mode (&optional arg)
(interactive "P")
(setq longlines-mode (not (or (and (null arg) longlines-mode)
(<= (prefix-numeric-value arg) 0))))
(if longlines-mode
;;everthing when mode is turn on
(progn
SAME CODE AS ABOVE)
;; Turn off longlines mode
(setq buffer-file-format (delete 'longlines buffer-file-format))
SAME CODE AS ABOVE
))
(or (assoc 'longlines-mode minor-mode-alist)
(setq minor-mode-alist
(cons '(longlines-mode " ll") minor-mode-alist))))
Is this correct?
Would the following be useful (instead of a (or (assoc ):
;;from reftex:
(if (fboundp 'add-minor-mode)
(add-minor-mode 'longlines-mode " ll"))
(unless (assoc 'reftex-mode minor-mode-alist)
(push '(reftex-mode " ll") minor-mode-alist)))
