Their Roundcube plugins (primarily developed to support the +Kolab Groupware server) have been extended by "Awesome IT" (a GbR out for Karlsruhe, Germany) +to support CalDAV calendars. + +Getting this all to work is a bit of a hassle so we - Faster IT GmbH - decided to +combine the various parts into a distribution when we were asked to implement this for a nonprofit company. +For the public benefit we re-publish the work under the origiginal AGPLv3+ license. + +This version is compatible with the [rcmcarddav plugin](https://github.com/blind-coder/rcmcarddav) +from [Benjamin Schieder](http://www.benjamin-schieder.de/carddav.html). +We hacked this by moving the ancient SabreDAV version the WebDAV driver uses into its own +`OldSabre` namespace so it does not collide with rcmcarddav's version. +We updated it to 1.8.12 which is the last version of the 1.x series (SabreDAV is at 3.1 now). + +That way you can have both CalDAV and CardDAV supported simultaneously in Roundcube by Free Software. + +There is work underway at "Awesome IT" to update SabreDAV to a recent version +(see their [gitlab](https://gitlab.awesome-it.de/kolab/roundcube-plugins/commit/5a0825b89a0b0183bf8469e66b667e294309b609)) +but at the time of writing this (2016-03-07) it has not yet been completed. + + +## Installation + +Clone the repository and copy `calendar` and `libcalendaring` to the `plugins` directory +of your roundcube installation: + + $ git clone git://github.com/fasterit/roundcube_calendar.git + $ cd roundcube_calendar + $ cd -r calendar/ libcalendaring/ /var/www/htdocs/roundcube/plugins/ # adjust as needed + +Copy and edit the supplied config.inc.php.dist: + + $ cd /var/www/htdocs/roundcube/plugins/ + $ cp config.inc.php.dist config.inc.php + $ $EDITOR config.inc.php + +Change the driver to include caldav (this is why you use this version of the calendar +plugins, right?); + + // backend type (database, kolab, caldav, ical) + $config['calendar_driver'] = array('database', 'caldav'); + $config['calendar_driver_default'] = 'caldav'; + +Provide a unique crypt_key.

It is a technique which can be used to isolate features of a particular shape within an image. Because it requires that the desired features be specified in some parametric form, the classical Hough transform is most commonly used for the de- tection of regular curves such as lines, circles, ellipses, etc. A generalized Hough transform can be employed in applications where a simple analytic description of a feature(s) is not possible. Due to the computational complexity of the generalized Hough algorithm, we restrict the main focus of this discussion to the classical Hough transform. Despite its domain restrictions, the classical Hough transform (hereafter referred to without the classical prefix ) retains many applications, as most manufac- tured parts (and many anatomical parts investigated in medical imagery) contain feature boundaries which can be described by regular curves. The main advantage of the Hough transform technique is that it is tolerant of gaps in feature boundary descriptions and is relatively unaffected by image noise."); +// $chars = "!# abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ 1234567890"; + for ($i = 0; $i < $len; $i++) + $title .= $words[rand(0,count($words)-1)] .
