I have a read-only file that I open in Emacs. I have created a keyboard shortcut to hide some regions of the file. For example:
(defun hide-beginning () (interactive) (setq buffer-read-only nil) (put-text-property 1 10 'invisible t) (setq buffer-read-only t) )
However, when I exit the buffer with
kill-buffer or rather
ido-kill-buffer, I get the question
Buffer myfile.txt modified; kill anyway? (yes or no)
How can this question be avoided?
