Readme
Non-blocking, temporal task sequencing. temporal
does NOT use setTimeout
or setInterval
, however there is a cost for using "recursive" setImmediate
to create an extremely fast, async execution loop. CPU usage is expected to peak when using temporal
, because the internal ticker needs to execute as fast as possible and as many times per second as possible. It's this speed that allows temporal
to review the internal schedule for tasks to execute more than once per millisecond, which is needed to create preferential execution cycles for hardware programming.
temporal
is for writing timing sensitive programs that are expected to be the primary process running on a given system, where the power source itself is tuned to accommodate that program specifically. Concrete examples include:
temporal
allows for sub-millisecond task scheduling through us of the resolution method.
temporal
is not good for sparse task scheduling.
npm install temporal
var temporal = require("temporal");
temporal.on("idle", function() {
console.log("Temporal is idle");
});
// Wait 500 milliseconds, execute a task
temporal.delay(500, function() {
console.log("500ms later...");
});
// Loop every n milliseconds, executing a task each time
temporal.loop(500, function() {
console.log("Every 500ms...");
// |this| is a reference to the temporal instance
// use it to cancel the loop by calling:
//
this.stop();
// The number of times this loop has been executed:
this.called; // number
// The first argument to the callback is the same as |this|
});
// Queue a sequence of tasks: delay, delay
// Each delay time is added to the prior delay times.
temporal.queue([
{
delay: 500,
task: function() {
// Executes 500ms after temporal.queue(...) is called
}
},
{
delay: 500,
task: function() {
// Executes 1000ms after temporal.queue(...) is called
// The last "delay" task will emit an "ended" event
}
}
]);
// Queue a sequence of tasks: delay then loop
// Each delay time is added to the prior delay times.
temporal.queue([
{
delay: 500,
task: function() {
// Executes 500ms after temporal.queue(...) is called
}
},
{
loop: 100,
task: function() {
// Executes 600ms after temporal.queue(...) is called
// Executes every 100ms thereafter.
}
}
]);
var temporal = require("temporal");
temporal.on("idle", function() {
console.log("Temporal is idle");
});
// Set temporal resolution to 0.1ms
temporal.resolution(0.1);
// Wait 0.7 milliseconds, execute a task
temporal.delay(0.7, function() {
console.log("0.7ms later...");
});
