Emacs: easily set timers with TMR

Raw link: YouTube OR Internet Archive

In this ~15-minute video I demonstrate a package of mine called tmr (pronounced as an acronym or as “timer”). It uses a simple notation to set the duration of a timer at the minibuffer prompt. Once the timer elapses, Emacs shows a notification. The desktop environment will also include one, as well as an audio alert (those are configurable). Timers can optionally have a description. They may also be listed in a tabulated/grid view, which makes it easier to work with them (to edit their description, reschedule them, etc.). Running timers may also be displayed on the mode line.

Sample configuration

(use-package tmr
  :ensure t
  :config
  (define-key global-map (kbd "C-c t") #'tmr-prefix-map)
  (setq tmr-sound-file "/usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga"
        tmr-notification-urgency 'normal
        tmr-description-list 'tmr-description-history))
