Open Source Scheme Interpreters

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

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).

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.

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.

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.

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...).

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.

Waxeye is a parser generator based on parsing expression grammars (PEGs). It supports C, Java, Javascript, Python, Ruby and Scheme.

Metaprogramming: proof of the concept.

Free & Compact Lisp Library for Java 5.0 and later

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).

Jawara is a lisp scripting language on Java/Android.

Julie is a Java-based implementation of R5RS Scheme, aimed for compatibility with the GNU Guile package.

Kawa is a full Scheme implementation. It implements almost all of R5RS (for exceptions see Restrictions), plus some extensions.

MScheme is a Scheme interpreter implemented in Java. The project goals are to fully comply with the "Revised^5 Report on Scheme" and a clean and modular design.

MiniJLisp is a minimal implementation of an interpreter for a Lisp style language in Java. MiniJLisp is designed to be used as an embedded extension language in Java programs.

Water: a fast, secure, dynamic OO language and database. Water is an all-purpose language (and meta-language) that runs Web applications in the browser or server-side. Water is compatible with .NET, Java, and C on Windows, Linux and Mac OS X system.

NexJ Scheme is an open source project providing an efficient and powerful Scheme interpreter that executes in a Java Virtual Machine.

An implementation of Scheme in Java.
