the work library has a function which it describes as 'cron for clojure functions':
https://github.com/clj-sys/work.git cant say i have used it, but i noticed it in there recently whilst looking for other things. here is the function: (defn schedule-work "schedules work. cron for clojure fns. Schedule a single fn with a pool to run every n seconds, where n is specified by the rate arg, or supply a vector of fn-rate tuples to schedule a bunch of fns at once." ([f rate] (let [pool (Executors/newSingleThreadScheduledExecutor)] (.scheduleAtFixedRate pool (with-log f) (long 0) (long rate) TimeUnit/SECONDS) pool)) ([jobs] (let [pool (Executors/newSingleThreadScheduledExecutor)] (doall (for [[f rate] jobs] (schedule-work pool f rate))) pool))) hope that is useful, cheers gaz On Fri, Jan 7, 2011 at 11:13 AM, Trevor <tcr1...@gmail.com> wrote: > What's the best way to kick off Clojure code at scheduled times?
