Have you ever wanted to be periodically reminded of something in Emacs
in an intrusive way? Perhaps, something like
for Emacs? Maybe you want to print a (de)motivational message every few
hours, or run some 1337-elisp to update your iWatch’s NTP server.
run-with-idle-timer. Here’s an example that displays a message
every four hours:
;; paste this into your *scratch* buffer ;; execute with M-x eval-buffer RET (defun debugging-advice () "Sage wisdom, from a computer." (interactive) (message "Have you tried turning it off and then on?")) ;; assign your timer to a variable. this is important -- without this, ;; you will be unable to easily cancel your timer (setq my-timer (run-with-idle-timer 14400 t 'debugging-advice)) ;; 4 hours (14,400 seconds) too soon? cancel it: ;; (cancel-timer my-timer)
You can view active timers with
C-h v timer-idle-list RET.
