SugarCubes

SugarCubes
A set of classes for reactive programming in Java

SugarCubes is a set of Java classes for implementing:

event based systems, especially those where events are instantly broadcast throughout the system. Communicating in this framework is like in radio transmissions, where emitters send information that is instantaneously received by all receivers.
concurrent systems, in particular thread-less ones. Here, parallelism is a logical programming construct to implement activities which are supposed to proceed concurrently, and not one after the other.
reactive systems, which continuously react to activations.

SugarCubes is used to implement Reactive Scripts and Icobj Programming on top of the Java language.

A paper (pdf file,48K) gives an overview of SugarCubes.

A comparison of Java threads and SugarCubes describes a small example of concurrent program coded with threads and with SugarCubes. A paper and the code of the example are available.

A new page with experimental versions of SugarCubes can be found here

A set of experiences in simulation of physical phenomena is done by Alexander Samarin on top of SugarCubes v3 and a variation of the Icobj framework. See this page for more information.

The SugarCubes v3 Java Doc (tar.gz file, 68K) This Documentation is under construction. It is at a very early stage of it is development, and many things are still not documented. It describes the SugarCubes programming interface.
The java doc is also accessible on line .
Most of the SugarCubes v3 framework is described in the PHD Thesis of J.-F. Susini in french (pdf file 2,4MB)

Examples:

HelloWorld: HelloWorld.java
Stops: Stops.java
HelloCube: HelloCube.java
Examples (60Kb) is a jar containing simple examples file that acts as a mini-tutorial for SugarCubes. (type jar xvf example.jar to extract source code). See also the README file included.
A variant of the famous reflex game can be found here: reflex.jar (60Kb).
Here is a good example of the power of the valued occurences of events: callback.jar (56Kb).
Now lets have a look to a simple example of code migration capabilities of the SugarCubes v3: migration.jar (60Kb). This demonstration requires another package, which is still under development: ReactiveKit.jar (12Kb).
