The home page for the Saxon XSLT 3.0, XQuery 3.1, and XPath 3.1 processor has moved to http://www.saxonica.com/. Information on this site is no longer kept up to date. Sourceforge was the home for open-source versions of the Saxon XSLT 3.0, XQuery 3.1, and XPath 3.1, processor from 1999 until 2022. From version 12.0 in January 2023, you need to visit the Saxonica site at http://www.saxonica.com/ for the latest information and releases.

Jython is a Java implementation of the Python language. It allows users to compile Python source code to Java byte codes, and run the resulting bytecodes on any Java Virtual Machine. It is the successor to JPython.

NOTE: Yacas and yagy development has moved to github. The new repositories are located at https://github.com/grzegorzmazur/yacas and https://github.com/grzegorzmazur/yagy . The mailing list has been moved over to https://groups.google.com/forum/#!forum/yacas . The downloads section at sourceforge will be kept up to date for the foreseable future. Yacas is an easy to use, general purpose computer algebra system. It uses its own programming language designed for symbolic as well as arbitrary-precision numerical computations. The system comes with a library of scripts and extensive documentation. Yagy (http://sourceforge.net/p/yagy) provides full yacas experience wrapped in a simple and intuitive graphical interface.

Lsl Plus is an edit/compile/test environment for the Linden Scripting Language (LSL), implemented as an Eclipse plug-in.

Lightweight, fast, Java-centric Lua interpreter written for JME and JSE, with string, table, package, math, io, os, debug, coroutine & luajava libraries, JSR-223 bindings, all metatags, weak tables and unique direct lua-to-java-bytecode compiling.

A MIPS processor modeled in Java for educational purposes and aimed at undergraduate Computer Architecture courses. It presently runs MIPS 32-bit R3000 ELF executables on any platform where Java itself will run. Five successively more sophisticated models of a pipelined MIPS RISC processor are included. Though the code is deliberately kept clear and simple in order that readers are able to figure out how a real processor works through the medium of the code, it will soon be able to run a real Linux O/S kernel compiled for MIPS in Java - at what speed we don't know!

Community Z Tools Project (CZT): Tools for editing, typechecking and animating Z specifications and related notations. Includes a Java framework for building formal methods tools. NOTE: development of CZT has now moved to GitHub: https://github.com/community-z-users/czt

JBasic is a traditional BASIC language intepreter written in Java for command line or embedded use. It supports conventional original DOS and MSBASIC syntax, plus some modern extensions for supporting threads, JDBC, etc. JBasic can be run directly from a shell.

SableCC is a parser generator which generates object-oriented frameworks for building compilers, interpreters and other text parsers. SableCC keeps a clean separation between machine and user code which leads to a shorter development cycle.

eXist-db is a native XML database featuring efficient, index-based XQuery processing, extensions for keyword search, XUpdate support, XSLT support, XForms support, REST and tight integration with existing XML development tools. Moved to Github - https://www.github.com/exist-db/exist

CJam is a stack-oriented programming language heavily inspired from GolfScript and suitable for code golfing. It is an interpreted language, and the official interpreter is written in java.

Un sistema de programación abierto, modular y flexible para fomentar las siguientes disciplinas: 1) programar para una interfaz, no para una implementación (GOF); 2) diseño por contrato; y 3) desarrollo dirigido por pruebas.

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.

JoSQL (Java Objects SQL) provides SQL capabilities for querying, ordering and grouping of collections of Java objects (POJOs). It allows a SQL statement to be applied to the collection of objects and the matching set returned, ordered and grouped.

RAVScript is designed as a procedural alternative to XSLT for XML to XML transformations. It is targeted at people with basic programming experience. It has similar syntax to Java (it is based on BeanShell), with some extensions to make transformation

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).

jAMOS is a cross platform, Java-based reimplementation of François Lionet's AMOS BASIC on the Amiga.

FScript is an simple, though powerful scripting language. Its intended use is as an embedded language in other Java programs. It's main benefits are simple extension options and small size (around 50k as a jar). FScriptME is FScript for J2ME.

JPype is an effort to allow python programs full access to java class libraries. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both Virtual Machines. Maintenance and evolution of the project has moved! please see http://www.jpype.org for the latest version

GUESS, or the Graph Exploration System, is a system and language for visualizing and manipulating graph structures and creating new visualization applications.

Jason is a fully-fledged interpreter for an extended version of AgentSpeak, a BDI agent-oriented logic programming language, and is implemented in Java. Using JADE a multi-agent system can be distributed over a network effortlessly. This project was moved to https://jason-lang.github.io

Smith is an open source, cross-platform ColdFusion® engine, written entirely in Java. Running on top of Java Runtime Environment and Java Servlet Container, it can be deployed virtually on any operating system and work with any web server.

A runtime inspection/scripting environment. Smalltalk-like Swing GUI for scripting engines and object inspection. Works on remote containers (EJB/Servlets) and of course locally. General BSF supported, comes with the Lisp-syntaxed language piji.

Co-op is a workbench for the definition and use of composition operators: abstractions that can encapsulate standard solutions such as coding idioms, design patterns and composition techniques, and can later be (re-) used just like library classes.
