Subject: Making a read-only buffer writable
Date: Tue, 12 Sep 2023 09:08:29 +0000 [thread overview]
Message-ID: <0dkHSu-LB9gHq-vWDPApgSFURUdqrdbAu7ZKq6k1LFAl6S7HJQ2sHmp3YCDJmAm-yqrbOxqQdne10jnbdUyfLwICE99HUEnPXkBzCJUgrNo=@protonmail.com> (raw)
Have been reading the documentation, any time one wants to write (insert) into a
read-only buffer, one has to make it writable. Doesn't matter when that time is.
If it's read-only you need to make it writable to write into it.
Then I wonder how it is possible for the following function
to call
(insert-button "[1]"
and
(insert " Graphic Organisation")
without calling
(setq buffer-read-only nil)
first, just after
(with-help-window (help-buffer)
-------------
(defun maces ()
"Prints information about frames."
(interactive)
(with-help-window (help-buffer)
(insert-button "[1]" 'action
(lambda (button)
(setq buffer-read-only nil)
(insert "> Graphic Organisation \n\n")
(setq buffer-read-only t)))
(insert " Graphic Organisation") ))
