How to clock-out current org-task before exit from Emacs? I tried

(add-hook 'kill-emacs-hook #'org-clock-out)

But if there is no current active tasks, Emacs says "No active clock" instead of exit. If there is an active task, in reality clock-out does not occur and the next time when I'm trying to make org-clock-in, see the proposal to resolve the conflict.

  • At least for the first part you can say (add-hook 'kill-emacs-hook (lambda () (org-clock-out nil t))). See the doc string for org-clock-out for the meaning of the parameters. I don't know why it does not clock out on exit though: you might want to edebug it and see if it does get called when you kill emacs.

(defun valeriy/exit ()
        (with-current-buffer (find-file-noselect org-main-file)
            (org-clock-out nil t)
(add-hook 'kill-emacs-hook #'valeriy/exit)
  • What is treport/org-main-file?

  • OK - I see: the "treport/" was a typo.
