README

systemd-related library. Currently: just a WatchDog notifier. WatchDog fires automatically if required from the environment. You're responsible for calling setReady() - and you might want to set Status and Reloading or error state.

Watchdog notifications will fire automagically based on whether systemd is running your daemon or not. In case we cannot detect systemd through our ENVironment, nothing happens - and the ifRequired() factory method will return false.

Usage

<?php

use gipfl\SystemD\NotifySystemD;
use React\EventLoop\Factory as Loop;

$loop = Loop::create();
if ($notifier = NotifySystemD::ifRequired($loop)) {
    $notifier->setReady('My process is ready');
    $loop->addTimer(10, function () use ($notifier) {
        $notifier->setStatus('Process status changed');
    });
}

$loop->run();

Naming

Yes, we know that it reads systemd and not SystemD - sorry for hurting your feelings. Unfortunately we released software depending on this library before we realized that we committed this error. We'll fix it once we move this to ipl or another namespace. Right now it isn't possible, as a transition from systemd to SystemD would lead to problems in a world with composer and PHP, with the latter being partially case insensitive.
