The iTask system (iTasks) is a task-oriented programming toolkit for programming workflow support applications in Clean.

With this toolkit, interactive systems can be specified using combinators in a very high level declarative monadic style. Programs are constructed by combining typed 'tasks'. These tasks produce results that can be passed as parameters to other tasks. Tasks are constructed by combining single steps sequentially or in parallel. From iTask specifications, executable web-based workflow support systems are generated automatically.

The iTask2 GUI

This latest version features:

  • A highly declarative API for specification of interactive systems as task compositions.
  • Automatic generation of web-based user interfaces for entering and updating and viewing data.
  • Automatic data persistance
  • Automatic instant synchronization between different clients using html5 push technologies.
  • Easy creation of JSON webservices
  • A builtin HTTP1.1 webserver
  • Integration framework for common client-side javascript libraries (for example google maps)


Get from subversion

The iTask system is actively developed, but not regularly released. Our version control is publicly accessible. You can get the development trunk from our subversion repository. You can get started with iTasks by following the following three steps:

  1. Install a Clean 2.4 system for 32-bit Windows.
  2. Check out the iTask trunk https://svn.cs.ru.nl/repos/iTask-system/trunk to a directory named 'iTasks-SDK' in your Clean 2.4 directory.
  3. Follow the setup instructions in README.txt

Documentation

Documentation of iTasks is still mostly done in scientific papers (look for iTasks on the Publications page).

Browsers

The iTask system works with most modern browsers. IE 9 is a known exception, we are working on that.

Using the iTask system with Firefox can be very slow. This is caused by a delay that is added by Firefox for all events for localhost. There are several solutions and workarounds:

  1. type as url: about:config
  2. search for v6, you will see network.dns.disableIPv6
  3. toggle the value of this parameter to True.
