Tactician plugin that allows scheduling a command to be executed at a specific time in the future, _(*1)

, _(*2)

Concept

This plugin allows you to create ScheduledCommands that will be executed at a specific time in the future., _(*3)

Usage

Make sure you put the SchedulerMiddleware in your CommandBus middleware chain:, _(*4)

// create your other middleware
$middleware[] = new SchedulerMiddleware(new FileBasedScheduler($pathWhereTheSchedulerMayKeepItsFiles) );
// create your other middleware
$commandbus = new CommandBus($middleware);

Let the command you want to schedule extend from AbstractScheduledCommand or implement the ScheduledCommandInterface. Create it and set a execution time:, _(*5)

class SayHappyNewYear extends AbstractScheduledCommand
{
    private $message;

    public function __construct($message)
    {
        $this->message = $message;
    }

    public function getMessage() 
    {
        return $this->message;
    }
}

$myScheduledCommand = new SayHappyNewYear('Happy New Year');
$myScheduledCommand->setTimestamp(strtotime('2016-01-01 0:00:00') );
$myCommandBus->handle($myScheduledCommand);

Create a bootstrap file that builds your Commandbus and cron the schedule execution command, for example bootstrap.php, _(*6)

// setup any environment you need
// create your other middleware
$middleware[] = new SchedulerMiddleware(new FileBasedScheduler($pathWhereTheSchedulerMayKeepItsFiles) );
// create your other middleware
$commandbus = new CommandBus($middleware);
return $commandbus;

Cron the scheduler at any interval you like (the more it runs, the better you can time your commands), example for once a minute, _(*7)

* * * * *   www-data    vendor/bin/scheduler scheduler:execute bootstrap.php

Or you can use the daemon command that ships with the package, to schedule an iteration every 10 seconds use:, _(*8)

vendor/bin/scheduler scheduler:daemon bootstrap.php 10

To make it stop after a minute use:, _(*9)

vendor/bin/scheduler scheduler:daemon bootstrap.php 10 6
