The JoCaml system

Cliquer ici pour la version française

The JoCaml system is an experimental extension of the Objective-Caml language with the distributed join-calculus programming model. This model includes high-level communication and synchronising channels,mobile agents, failure detection and automatic memory management. JoCaml enables programmers to rapidly develop distributed large-scale applications, using both Objective-Caml ease of programmation and extended libraries, and the join-calculus distributed and concurrent features. It can already be viewed as the next-generation Internet programming language.

The distribution

The current distribution contains:

• The Objective-Caml distribution, version 1.07
• The Join library, included in the distribution
• Lots of examples:
  • Bomberman: The famous game, rewritten by Joachim Tordjman.
  • The Netscape Plugins: to run JoCaml applets under Netscape, written from Calves by Joachim Tordjman.
  • Pong: The pong game, written by Sylvain Conchon.
  • Bataille: The navy war game, written by Sylvain Conchon.
  • Tron : The tron game, written in join by Luc Maranget, and translated in JoCaml by Fabrice Le Fessant.
  • Mandel: 3 versions of the mandelbrot fractal, written by Luc Maranget for the join system, and translated by Fabrice Le Fessant. One of these versions is a program mixing bytecode and native code.
  • Hevea server: a patch to apply to HeVea 1.01, to make it move as a mobile agent from a server to different clients.
