========
Periodic
========

Periodic is a fully unit tested PHP based task runner. It is supposed to
deliver a basic implementation for managing all kinds of recurring tasks and
events inside your web application. It has been designed with having all kinds
of different web hosting environments in mind. It is capable of running on
most shared hosting systems as well as root servers.

Motivation
==========

We needed some kind of recurring task management system for different projects
we are currently working on. We first started working on some kind of
CronjobIterator which is capable to parse a cron definition -- you might know
this definitions from the famous vixie-cron__ daemon -- and provide an iterable
list of timestamps matching this definition. The vcron__ definition syntax
seems to be the most intuitive and widely spread syntax to describe recurring
events, therefore we chose it.

We wrote a `design document`__ for it and started discussing it. We tried to
create a modular and flexible system fulfilling the needs of multiple of our
projects.

Download and test

There is no release yet, but you can `check it out from SVN`__. We would like
to ask you to test it and provide feedback.
