Subject: Re: Strange behaviour of auto-fill
Date: Sat, 24 Apr 2021 02:47:16 +0200	[thread overview]
Message-ID: <trinity-5a963c17-191b-4d97-bcf2-b7e62ebbe482-1619225236100@3c-app-mailcom-bs03> (raw)

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)) ))
