Re: Strange behaviour of auto-fill

[michael-franzese@gmx.com]

Have tried to do something but gets me

error: Unknown string-match pattern: (string-match "on-off" s)

-----

(defun break-line-order ()
   (setq order "off-on")
   (pcase
      ((string-match "off-on" s)
          (setq break-line 0)
          (message "%s" "break-line-order: off-on"))
      ((string-match "on-off" s)
          (setq break-line 1)
          (setq-default auto-fill-function 'do-auto-fill)
	  (message "%s" "break-line-order: on-off")) ))

(break-line-order)
