Description

This project is inspired by the Laravel's Schedule component and tries to bring it's simplicity to the Yii framework. Quote from Laravel's documentation:, _(*6)

In the past, developers have generated a Cron entry for each console command they wished to schedule. 
However, this is a headache. Your console schedule is no longer in source control, 
and you must SSH into your server to add the Cron entries. Let's make our lives easier.

After installation all you have to do is to put single line into crontab:, _(*7)

* * * * * php /path/to/yii yii schedule/run --scheduleFile=@path/to/schedule.php 1>> /dev/null 2>&1

You can put your schedule into the schedule.php file, or add it withing bootstrapping of your extension or application, _(*8)

<?php
/**
 * @var \powerkernel\scheduling\Schedule $schedule
 */

// Place here all of your cron jobs

// This command will execute ls command every five minutes
$schedule->exec('ls')->everyFiveMinutes();

// This command will execute migration command of your application every hour
$schedule->command('migrate')->hourly();

// This command will call callback function every day at 10:00
$schedule->call(function(\yii\console\Application $app) {
    // Some code here...
})->dailyAt('10:00');

Next your should add the following command to your crontab:, _(*24)

* * * * * php /path/to/yii yii schedule/run --scheduleFile=@console/config/schedule.php 1>> /dev/null 2>&1

That's all! Now all your cronjobs will be runned as configured in your schedule.php file., _(*25)

How to use this extension in your own extension?

First of all, you should include dependency to the powerkernel\yii2-scheduling into your composer.json:, _(*26)

...
'require': {
    "powerkernel/yii2-schedule": "*"
}
...

Next you should create bootstrapping class for your extension, as described in the http://www.yiiframework.com/doc-2.0/guide-structure-extensions.html#bootstrapping-classes, _(*27)

Place into your bootstrapping method the following code:, _(*28)

public function bootstrap(Application $app)
{
    if ($app instanceof \yii\console\Application) {
        if ($app->has('schedule')) {
            /** @var powerkernel\scheduling\Schedule $schedule */
            $schedule = $app->get('schedule');
            // Place all your shedule command below
            $schedule->command('my-extension-command')->dailyAt('12:00');
        }
    }
}

Add to the README of your extension info for the user to register schedule component for the application and add schedule/run command to the crontab as described upper., _(*29)

Using schedule component

You do not have to use schedule component directly or define it in your application if you use schedule only in your application (and do not want to give ability for extensions to register they own cron jobs). But if you what to give extensions ability to register cronjobs, you should define schedule component in the application config:, _(*30)

'schedule' => 'powerkernel\scheduling\Schedule',

Using addition functions

If you want to use thenPing method of the Event, you should add the following string to the composer.json of your app:, _(*31)

"guzzlehttp/guzzle": "~5.0"

Note about timezones
