I am trying to set "auto-fill", with some tools to change "on-off" behaviour.

Things get very confusing.  When I comment out "(setq-default auto-fill-function 'do-auto-fill)", "auto-fill-mode" will still break comments even though "break-line" is "0"
and one sets "(auto-fill-mode 0)".



(setq-default auto-fill-function 'do-auto-fill)
(defvar break-line 0)

(defun break-line-ddd ()
  "Breaks long lines using auto-fill tool."
  (interactive)

  (pcase break-line
    ((or 'nil 0)
       (setq comment-auto-fill-only-comments nil)
       (auto-fill-mode 0)
       (message "%s %s"
		"Disable: Break line;  " break-line)
       (setq break-line 1))
    (1
       (setq fill-column 72)
       (setq comment-auto-fill-only-comments t)
       (auto-fill-mode 1)
       (message "%s" "Enable: Break only comments")
       (setq break-line 2))
    (_
       (setq comment-auto-fill-only-comments nil)
       (auto-fill-mode 1)
       (message "%s" "Enable: Break all long lines")
       (setq break-line 0)) ))

(defun break-line-set ()
  "Breaks long lines using auto-fill."
  (break-line-ddd)
  (global-set-key (kbd "H-b") #'break-line-ddd) )

(break-line-set)

Have had a go months ago on that.  It totally defeated me and gave
up on it.

Have had another go and noticed that calling

  (turn-off-auto-fill)

will not break lines if the following is present

  (setq-default auto-fill-function 'do-auto-fill)

My impression would be for developers to take a closer look at the
code, so that it's use would be simplified.  Or perhaps some good
examples on how to use it, as it does not look so clear to me.

Actually, when I call (turn-off-auto-fill) after calling
(setq-default auto-fill-function 'do-auto-fill) does tell
turn the mode off.

You are right, I meant to say that turn-off-auto-fill
does not respond as it should when you use
(setq-default auto-fill-function 'do-auto-fill)

I am trying to write a workaround, but am struggling with elisp.
Would like to have a function that sets the order.  But do not
know how to make string variables, then use pcase.

(defun break-line-order ()
   (setq n )
   (pcase n
      ("off-on"
          ;; initially do not break lines
          (setq break-line 0))
      ("on-off"
          ;; initially break lines
          (setq break-line 1)
          (setq-default auto-fill-function 'do-auto-fill)) ))
