Re: Removing line and column number settings from some buffers

Look at this code.  Correct, you don't need a variable for storing,
but what is happening with n in the following code.

The byte compiler complains about the variable n

(defun auto-fill-cycle ()
   "Cycles Auto Fill.  Automatically breaks lines that get beyond
variable fill-column."
   (interactive)

   ;; ----- body of let -----
;;   (unless (get 'auto-fill-cycle 'state)
;;      (put 'auto-fill-cycle 'state 1))

   (setq-local n (get 'auto-fill-cycle 'state))

;;   (when (= n 1)
   (when (or (not n) (= n 1))
      (message "Auto Fill Comments Only")
      (set (make-local-variable 'comment-auto-fill-only-comments) t)
      (auto-fill-mode 1)
      (put 'auto-fill-cycle 'state 2))
   (when (= n 2)
      (message "Auto Fill Whole Buffer")
      (set (make-local-variable 'comment-auto-fill-only-comments) nil)
      (put 'auto-fill-cycle 'state 3))
   (when (= n 3)
      (message "Disable Auto Fill")
      (auto-fill-mode 0)
      (put 'auto-fill-cycle 'state 1)) )

(global-set-key (kbd "H-a") #'auto-fill-cycle)
