I feel a little weird just enabling this, let's see what I think about auto-killing any buffer older than six hours. It won't run often, if I want it to run hourly, I could put it in to a repeating timer, myself.
emacs-lisp source:(provide 'cce/midnight-mode) (setq clean-buffer-list-delay-general 0.5) (midnight-mode 1) (setq clean-buffer-list-kill-regexps (append clean-buffer-list-kill-regexps (list (rx line-start "*Ement")))) (setq clean-buffer-list-kill-never-buffer-names (append clean-buffer-list-kill-never-buffer-names (list "*Group*")))
I really wish this clean-buffers functionality could exclude based on mode, what an oversight! We can cheese it, however, with this function which can be added to help:clean-buffer-list-kill-never-regexps.
emacs-lisp source:(defun cce/check-kill-exwm-mode (buffer-name) "Checks whether the buffer backing [`buffer-name'] is an EXWM-mode buffer to exclude from midnight-mode. To enable this, add it to [`clean-buffer-list-kill-never-regexps'], which will get it funcall'd in the midnight-mode hook." (with-current-buffer buffer-name (eq major-mode 'exwm-mode))) (add-to-list 'clean-buffer-list-kill-never-regexps #'cce/check-kill-exwm-mode)
