last-non-white-space-on-line

[Andreas Roehler]

Hi, 

is there a function known to jump to the last
non-whitspace char in line - as (back-to-indentation)
does in the other direction?

Could write something like 

(defun last-non-white-space-on-line ()
  " "
  (interactive)
  (end-of-line)
  (skip-chars-backward "[ \t]")) 

Nonetheles, would prever to use an already existing
macro.

Thanks

I'd suggest

   (skip-chars-backward " \t"))

instead.

Not one function of course, but I would do C-e M-\
This deletes the whitespace, but that's what I want to happen
anyway if I'm not adding more to the line.

Basicaly you are right, don't imagine any use of
whitespaces at the end of line.

BTW.: Got a hint concerning an error in the previous
draft. Here a better one:

(defun last-non-white-space-on-line ()
  " "
  (interactive)
  (end-of-line)
  (skip-chars-backward " \t"))

;; To do it with  (delete-horizontal-space):    

(defun last-non-white-space-on-line ()
  " "
  (interactive)
  (end-of-line)
  (delete-horizontal-space)        
  ;;   (skip-chars-backward " \t")
  (backward-char 1))
