Re: How to avoid SPACE TAB in a file?

[Ulrich Neumerkel]

Thanks again for your responses.  Currently I put in my .emacs.el

(defun no-space-tab ()
  (interactive)
  (let
      ((point (point)))
    (save-match-data
      (goto-char (point-min))
      (cond
       ((search-forward " \t" nil t)
        (backward-char 1)
        (error "SPACE found prior to TAB! Press Backspace"))
       (t (goto-char point))))))

(add-hook 'after-save-hook 'no-space-tab)
