Hi,
I've made a crude hack to jump to a window with specific number, the
functions are available at
http://www.emacswiki.org/cgi-bin/wiki.pl?SwitchingWindows
and have been revised a little by better elisp hackers than me :)
This has resulted in my desire to display the window[1] number in the
mode line. So far I've the following function to evalute the number
of the selected window:
(defun my-window-number ()
(number-to-string
(1- (length (memq (selected-window) (nreverse
(window-list)))))))
Then I create this list with items I want to show in the modeline:
(setq window-number-string
(list "W"
'(:eval (my-window-number)) " "))
And add it to the global-mode-string:
(add-to-list 'global-mode-string '("" window-number-string))
But I only get an "W " in the modeline, the number doesn't show up!
Can anyone tell my why this is and how to do it?
And so people won't get confused, I'm using GNU Emacs version 21.[23].
Thanks in advange,
Johann
1 Emacs terminology, this has nothing to do with an os or even a
window system.

I can not really help you - but some comments:
1. The *global*-mode-string is just that - i.e. it is gloablly shared
among all windows (and even frames) - hence any code which simply
sets global-mode-string to some value will result in the same value
displayed in all windows. So (as far as I can see)
global-mode-string is not the variable to use - others can maybe
suggeste another variable to use for this?

2. global-mode-string is a string - not a list. The following
implements (my understanding of) what you want to achieve, but with
the caveat mentioned above:
(setq global-mode-string (format "Window: %s" (my-window-number)))
The natural solution (if you can solve problem 1) above, would be
to wrap this in a function, and then add this function as a hook
called when splitting windows (I don't know if there is any such
hook).
Good Luck
Joakim

The (:eval ..) construct is though unique to each modeline.

Actually, global-mode-string is a list, and now there are two methods
that show the window number in the modeline at the above url. The
latter is a fixed version of what I was trying to do.
Thanx though,
Johann

(add-to-list 'global-mode-string window-number-string)
