iCalendar Export Plugin

There are some Calendaring tools that don't yet support CalDAV, but they do have support for the 'Subscribe to' feature.

Starting with SabreDAV 1.4, there is now a plugin that grabs an existing calendar, and exports it as a file that's compatible with these applications.

Setup

To use this plugin, simply add it to your server:

$icsPlugin = new \Sabre\CalDAV\ICSExportPlugin();
$server->addPlugin($icsPlugin);

After this is added, you can generate these exports by finding a url to your calendar, and adding ?export at the end of the url. This will automatically trigger a download.

Sample url

http://dav.example.org/calendars/user1/mycalendar?export

Options

The ICSExport plugin supports several options since version 2.0.
