Wren-cli supports the scheduling of tasks using a timer.
The tasks to be executed are added to a list by the Scheduler class. The Timer.sleep method suspends the current fiber and signals the scheduler (by calling a private method) to execute the tasks one by one in their own fibers - in Wren only one fiber can execute at a time. The task results are then available to the main fiber on its resumption after Timer.sleep has completed.
<lang ecmascript>import "scheduler" for Scheduler
import "timer" for Timer
var a = 3
// add a task
Scheduler.add {
a = a * a
}
// add another task
Scheduler.add {
a = a + 1
}
System.print(a) // still 3
Timer.sleep(3000) // wait 3 seconds
System.print(a) // now 3 * 3 + 1 = 10</lang>
