trailing whitespace visible on some buffers

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

Calendar's buffer hooks (was trailing whitespace visible on some buffers)

With your help I've almost solved the problem, I just need to
know the name of the hooks that take place after the
*calendar* buffer is created.

I've tried the following variants: (after making visible
whitespaces globally)

1. (add-hook 'today-visible-calendar-hook
          (lambda ()
            (setq show-trailing-whitespace nil)))

==> the whitespaces disappear only when I scroll the calendar
   or hit "d" or "h".

2. (add-hook 'calendar-load-hook
          (lambda ()
            (setq show-trailing-whitespace nil)))

==> whitespaces don't disappear.

Any suggestions?

Thanks in advance

I've been trying to do the same thing for a while. Unfortunately my
knowledge of lisp is nonexistent :( I use the diary and calendar and
have been using the following in my ~/.emacs

(defun simon-calendar-function ()
  (turn-off-auto-fill)
  (turn-off-filladapt-mode)
  (flyspell-mode nil)
  (setq show-trailing-whitespace nil)
)
(add-hook 'calendar-mode-hook 'simon-calendar-function)
(add-hook 'diary-hook 'simon-calendar-function)

This works fine for the diary, but I still have the white space
markers in my calendar. I have also tried using the calendar-load-hook.

Any ideas?

Simon.

calendar-mode-hook isn't defined.  Try:

(add-hook 'initial-calendar-window-hook 'simon-calendar-function)

I just found it's documented in the manual:

File: elisp,  Node: Calendar Customizing,  Next: Holiday Customizing,  Up: Calendar

Customizing the Calendar

[...]

   Starting the calendar runs the normal hook
`initial-calendar-window-hook'.  Recomputation of the calendar display
does not run this hook.  But if you leave the calendar with the `q'
command and reenter it, the hook runs again.

I don't know why but, when using
`initial-calendar-window-hook' in the following:

(setq-default show-trailing-whitespace t)
...
...
(add-hook 'initial-calendar-window-hook
          (lambda ()
            (setq show-trailing-whitespace nil)))

the trailing whitespace disappears only partially (!!!???) and,
after some event take place (or after some time --~30 sec.)
(!!!???), it disappears completely. The result is similar to
the one obtained using the hook: `today-visible-calendar-hook'.

Could anybody explain why this delay happens?
Thank you.

luis

It works for me as it should.  Please, consider to file a bug report
after updating to version 21.2.

For bug reporting read the manual: C-h r mBugs RET .
