(let ((hook (lambda () (setq show-trailing-whitespace nil))))
  (mapc (lambda (var)
          (add-hook var hook))
        '(info-mode-hook calendar-mode-hook diary-hook)))

Untested.

Sorry, I don't know what the *mail presentation* buffer is.

Edward,

Thank you for your message (Sat, 14 Sep 2002 09:57:12 GMT), in

Well, I've tested it and, unfortunately, it doesn't work for
me. I don't understand why it doesn't work, since your
suggestion seems to be appropriate (given my limited knowledge
of lisp).

I mean the presentation of my mail folders in VM (View Mail).

On the basis of your suggestion I made some tests without
success. I always have to do `M-x set variable RET
show-trailing-whitespace RET nil RET' once per buffer to do
the trick. May be there are other suggestions?

Thank you
luis

E.g., it's "Info-mode-hook" (note the upper case letter).  I'm using
this simple code:

(add-hook 'Info-mode-hook
          (lambda ()
	    ;; (define-key Info-mode-map "=" 'delete-other-windows)
	    ;; (define-key Info-mode-map "1" 'delete-other-windows)
	    (setq show-trailing-whitespace nil)))

I didn't check the other mode hook names.

Dear Karl,

Thank you for your message (Sat, 14 Sep 2002 20:56:23 +0200),

Yes, after testing Edward's suggestion I found that the problem
was that I was using incorrect mode hook names.

   Karl>           (lambda ()
   Karl> 	    ;; (define-key Info-mode-map "=" 'delete-other-windows)

   Karl> 	    (setq show-trailing-whitespace nil)))

Thanks to you I've solved my problem with *info* (thanks to
Edward I solved it for *diary*). It remains the
*calendar*. I've probed some mode hook names (including
calendar-load-hook) without success. Are there some
suggestions on this?

Thank you very much
luis

Did you consider writing a bug report to suggest that the superfluous
whitespace should be removed from all the info files that come in the Emacs
distribution (which would make a significant improvement, at least)?
I see it too but I did not [yet] manage to write a bug report about it.

Dear Michael,

Thank you for your message (16 Sep 2002 10:39:51 -0700), in

Yes, I've considered it. However I think that the bug isn't in
the Emacs info documents, but in info formating machine, since
what we see has been formatted with texinfo, hasn't it? After
formating there musn't be trailing whitespaces. Please correct
me if I'm wrong, I'm a complete ignorant, who wants to post
his first bug report to the correct address.

Thank you very much,
luis

trailing whitespace visible on some buffers

[Luis O. Silva]

Dear Emacs community,

This is an elementary question, but I haven't found the
solution of my problem.

I want to set the buffer-local variable
`show-trailing-whitespace' to `t' for all buffers except
for *info*, *diary*, *calendar*, and *mail presentation*. In
the emacs node of info I found how to set local variables to
different _modes_ using "hooks", but I don't know how to set
buffer-local variables to concrete buffers.

Thank you very much in advance,
luis
