Usage

The following is a barebones example for how to use scheduled.

import std.stdio;
import core.time;
import std.datetime;

import scheduled;

void main() {
	JobScheduler scheduler = JobScheduler.getDefault();
	scheduler.addJob(
		() => writeln("Executing at " ~ Clock.currTime.toISOExtString),
		new FixedIntervalSchedule(seconds(12))
	);
	scheduler.start();
}

In addition to the FixedIntervalSchedule, the following is a list of all supported schedules:

  • OneTimeSchedule - Executes a job once, at a specified timestamp.
  • FixedIntervalSchedule - Executes a job repeatedly, according to a specified Duration interval.
  • DailySchedule - Executes a job one or more times per day, at specified times.
  • CronSchedule - Executes a job according to a Cron expression. For a precise overview of the supported cron syntax, please refer to Maxim Tyapkin's cronexp library.

By default, the library comes with the following JobScheduler implementations:

  • TaskPoolScheduler - Scheduler which runs as a thread, and uses a TaskPool to execute jobs. It keeps all scheduled jobs in a priority queue, and sleeps until the nearest job should be executed.
