reload customization

reload customization

[Haines Brown]

In my init file I have

  (defun reload () "Reloads .emacs interactively."
    (interactive)
    (load "~/.emacs"))

The problem is that I also have

  (split-window-horizontally)

As things now stand, a reload splits current window so that I end up
with three. I'd like to have reload instead preserve the two window
split.

Wrap it with save-window-excursion:

(save-window-excursion
  (load "~/.emacs"))

You should read the caveats in

Thanks, Barry, that was the answer I needed.

In case anyone's following this, there was a typo in the URL you
provided. With spelling of Configurations corrected and pehaps a more
specific location, it would be:

There was no typo when I posted it. Looks like the news->mail gateway 
added a newline when it wrapped it. AFAIK, MT-NW doesn't do this when 
sending, because I've never had a problem with long URLs before.

you could wrap that into :
(unless (window-parent)
   (split-window-horizontally))
