Open Source Scheme Software

In this project we aim to develop scheme libraries for developing various web applications (especially servlets and xml-based web services). Our approach is to use jscheme (an open source implementation of scheme in Java) as the core language which allow

A quantitative finance C++ library for modeling, pricing, trading, and risk management in real-life. A cross-platform free/open-source tool for derivatives and financial engineering.

SISC is an extensible Java based interpreter of the algorithmic language Scheme. SISC uses modern interpretation techniques, and handily outperforms all existing Java interpreters (often by more than an order of magnitude).

An implementation of the language described in "Karel the Robot: A Gentle Introduction to The Art of Programming" by Richard Pattis et al. Both Java and C/Unix versions are available.

ECB is a file/code browser for Emacs. It can be used to browse any type of file and supports parsing of Java, C, C++, Elisp and some other code like perl, TeX, LaTeX. All browsing windows are within one frame and they are deletion-protected (eg by C-x 1)

A language designed for server-side WWW-based applications, particularly database applications. It is based on Scheme, which makes the syntax extremely simple yet powerful. This implementation is a Java Servlet using the Kawa Scheme compiler.

FramerD is a distributed semi-structured object database originally developed at MIT. It provides an internationalized Scheme-based scripting language, built-in text analysis tools, and special support for web scripting.

Momoko is a framework for developing distributed, multi-user, network-aware applications. It includes facilities for storing objects in a tree structure, a shell for manipulating the object database, orthogonal persistence, scripting support, and a trans

A set of Eclipse plugins for the Scheme programming language. Features a powerful, fully extensible S-expression-based editor. Integrates seamlessly with any Scheme interpreter.

several vaguely related projects worked on by me: a 3d engine with a javascript-like scripting language (pdsys); an older scheme dialect (vmsys); ... (2009-04-28: I have been gone for years, may try to put up some newer stuff...).

AntWar! is a virtual life simulator. The player must extends the base ants classes to create their own colonys whose must survive in the warfield.

A Windows native distribution of Bigloo, a Scheme system that includes an optimizing compiler generating C code, Java classes and .NET CIL files as well as an interpreter.

The purpose of the project is to develop a quantitative medical imaging & visualization program for use on brain MR, DTI and MRS data. It is a joint project of the Kennedy Krieger Institute & the Johns Hopkins University, Psychiatric Neuroimaging Lab

Cassowary is an incremental constraint solving toolkit that efficiently solves systems of linear equalities and inequalities. Constraints may be either requirements or preferences. Re-solving the system happens rapidly, supporting UI applications.

A Java applet-based shared programming whiteboard system, to use with any programming language with a suitable Java Virtual Machine implementation

Codename Alpha will (when finished) be a realtime strategy game (RTS), written entirely in Java. For now, it is a Java RTS engine with a small testgame (including one kill-all mission). AI uses an integrated trampoline-style cps-interpreter for scheme.

Metaprogramming: proof of the concept.

Free & Compact Lisp Library for Java 5.0 and later

The FermaT toolset is the implementation of the FermaT Transformation Technology which developed semantic preserving code transformations to simplify programs without changing their behavior. The correctness is guaranteed by mathematical proof.

Formicidae is the official simulator and visualizer for the Ant-Wars competitive programming site, written in Java and SISC. The site is hosted at www.ant-wars.net.

Fungus is a framework for distributed simulation by multi-agents. It uses a very modular architecture. A GUI is provided. In our model, everything is Agent. Even the environnement. You have an access to the communication's 'canals'.

Gleam is a simple Scheme language interpreter written in Java. Project goals: to support the discovery of Scheme for beginners, simplicity, R5RS compliance, full integration with the Java platform (call Java from Scheme and vice versa).

The goal of this project is to develop groupware libraries in Scheme and to use these libraries to develop groupware applications.

Tool for playing tabletop roleplaying games, like Dungeons and Dragons, over the internet.

JSchemePlus is an hack of Jscheme 1.4 by Peter Norvig. It allows to redistribute a script in an executable JAR file of only ~40K and implements all of R4RS with a lot of additional functions, like: (execute command) (random) (sequence from up-to step) (split list element) (string-split string sub-string) (read-all-from-file file) (write-to-file file data) (file-size file) etc... For the complete list read the HELP file or type (help). JSchemePlus needs only the Java Virtual Machine (version 6 or higher) that, in the case, is very easy to download and install.
