alarm clocks and timers in Emacs?

[Devin Prater]

Hi all. Does anyone know if there are any kinds of alarm clocks or
timers in Emacs, or in Elpa or Melpa? Just one of those things I’d like
to have in my… Desktop.

Org-mode has various timers.

Thanks for this. I'll take a look. A use case for me would be to set a
timer for when I’m on break during the day, setting a timer for maybe 10
minutes, and recieve a sound, or something Emacspeak could say, to let
me know that time is up so I can prepare to work again. If Org mode can
do all that, then it is powerful indeed!

I do exactly this right now. Check out the package 'pomodoro'. This is my
startup code to make use of it. 

(require 'pomodoro)
(global-set-key (kbd "<C-f1>") 'pomodoro-start)
(global-set-key (kbd "<C-f2>") 'pomodoro-stop)
(global-set-key (kbd "<C-f3>") 'pomodoro-pause)
(global-set-key (kbd "<C-f4>") 'pomodoro-resume)
(fset 'pomodoro " [ ]")
(pomodoro-add-to-mode-line)

You customize within 'pomodoro' to set your timers and your sounds. I
use a tea-kettle whistle to stop work and a factory whistle to start
again. Plenty of sound files out there to choose from.

See the entries timers [1] and idle timers [2] in the Emacs Lisp manual.

Basically, you call

  (run-at-time "12:00" my-function)

for calling my-function at an absolute time, or

  (run-at-time "1 min" my-function)

to call my-function a minute from now. Repeats can be specified, etc.

The "idle" variants are for when you want to specify that Emacs be idle
for that long to actually call your function.

See the docs for the gories. Or ask here for more specifics.
