Simple ICal Exporter library

requires Twig templating engine to render ICS files.

Installation:

composer require acrnogor/ical-exporter

Usage:

// first, we need Twig environement
$loader = new Twig_Loader_Filesystem();
$twig   = new Twig_Environment($loader, [
    'cache' => __DIR__ . '/var/cache',
]);

// now create new ICalExporter object and download event items as ICS file
$filename = 'this-is-my-calendar.ics';
$icalExporter = new ICalExporter($twig);
$ice->downloadAsICal($items, $filename);

Or, if you just want ICS body as string/text:

// you an either repeat Twig part or just use Dependency Injection (i.e. in Symfony) to inject twig to the class, then fetch it as a service
...

// now create new ICalExporter object and download event items as ICS file
$icalExporter = new ICalExporter($twig);
$icsText = $ice->getICalDataAsString($items);
echo $icsText;

Symfony 3.0+ usage

Add ICalExporter to your Symfony project via composer install. Then, define a Symfony service in your services.yml:

ical_exporter:
    class: Acrnogor\ICalExporter\ICalExporter
    arguments: ["@twig"]

and then register template path in twig configuration in config.yml:

twig:
    paths:
        '%kernel.root_dir%/../vendor/acrnogor/ical-exporter/src/View/': ~

then you can use this service in your controller like zis:

$icalExporter = $this->get('ical_exporter');
$icalExporter->downloadAsICal($events, 'give-some-filename.ics');

Todo:

• maybe implement a non twig version? Meh...
