kill buffer in other window

kill buffer in other window

[Florian Kaufmann]

Hello

Say you called something that displays a new buffer in the 'other
window', e.g. describe-function, grep. When you done reading that
buffer, you want to undo the displaying. That is kill the buffer, and
delete the window if one was created. I din't found yet a convenient
way to do it. Of course I can write a small lisp function, but I think
there are other cool ways.

Greetings

Flo

First, don't get hung up on killing the buffer. Buffers like *Help*
don't use much resoruces and the buffer will be reused next time you use
help. I've often got many buffers open in emacs at a time (normally
around 30 or more). 

All you want is to have the buffer not use up valuable display space. To
do this, use the window commands. For example, when a help buffer pops
up and your finished with it, just hit C-x 1 from within the buffer you
want to stay and the help buffer will vanish while your current buffer
expands to fill the frame.

You might want to check out electric-help (ehelp.el).  There is nothing 
more satisfying than the window disappearing when you think it should!

Here is a short code snippet which gets ride of a hanging compilation
window if compilation was successful. Taken from some .emacs file
found on the wiki.

;; I also don't like that the compilation window sticks around after a
;; successful compile. After all, most of the time, all I care about
;; is that the compile completed cleanly. Here's how I make the
;; compilation window go away, only if there was no compilation
;; errors:
 (setq compilation-finish-function
       (lambda (buf str)
         (if (string-match "exited abnormally" str)
             ;; there were errors
             (message "compilation errors, press C-x ` to visit")
           ;; no errors, make compilation window go away in 0.5 sec
           (run-at-time 0.5 nil 'delete-windows-on buf)
           (message "NO COMPILATION ERRORS!"))))


I use something similar to get rid of a hanging help window when
compiling successfully a tex file using auctex.

(defadvice TeX-command-master (after kill-Help-window)
 (if (and TeX-error-report-switches
     (plist-get TeX-error-report-switches
       (intern (plist-get TeX-error-report-switches 'TeX-current-
master))))
            (TeX-next-error 1)
       (when (get-buffer "*TeX Help*")
         (set-buffer "*TeX Help*")
         (kill-buffer-and-window))))
(ad-activate 'TeX-command-master)
(setq TeX-process-asynchronous nil)


Hope this helps.

I took this from http://www.mygooglest.com/fni/dot-emacs.html#sec4:

    ;; don't show output of TeX compilation in other window
    (setq TeX-show-compilation nil)

Works for me...
