timeout is a small library to help you throttle or debounce elisp function calls. See this write-up for an introduction and potential uses.
It’s actually tiny, just a couple of functions.
You can throttle an elisp function func to run at most once every 2 seconds:
(timeout-throttle! 'func 2.0)To reset func:
(timeout-throttle! 'func 0.0)When the call is a noop, a throttled function will return the same result as the last successful run.
You can debounce an elisp function func to run after an uninterrupted delay of 0.5 seconds:
(timeout-debounce! 'func 0.5)To reset func:
(timeout-debounce! 'func 0.0)By default a debounced function returns nil at call time. To change this, run:
(timeout-debounce! 'func 0.5 'some-return-value)
