Projects

Parrot

Parrot is a virtual machine designed to efficiently compile and execute bytecode for dynamic languages. Parrot currently hosts a variety of language implementations in various stages of completion, including Tcl, Javascript, Ruby, Lua, Scheme, PHP, Python, Perl 6, APL, and a .NET bytecode ... [More] translator. Parrot is not about parrots, though we are rather fond of them for obvious reasons. [Less]

Clojure

Clojure is a dynamic programming language for the JVM. It is interactive, yet compiled, with a robust infrastructure for concurrency (STM). It is a functional dialect of Lisp, with a rich set of immutable, persistent data structures and a macro system.

Mozilla Rhino

claimed by Mozilla Foundation

Rhino is an open-source implementation of JavaScript written entirely in Java. It is typically embedded into Java applications to provide scripting to end users.

Open Komodo

The OpenKomodo Open Source Development Environment for Dynamic Languages and Web Technologies The Open Komodo project provides a code base upon which integrated development environment (IDE) software packages can be developed. ActiveState's Komodo Edit 4.3 and later (an open source ... [More] , multi-platform, multi-language editor) is an established, mature product that uses the Open Komodo platform. With the Open Komodo Project, the focus is on dynamic languages and the open web. Open Komodo is developed on top of many open source technologies, including Mozilla, Python, and Scintilla. The primary development technologies used are XUL, JavaScript, Python, and C/C++. [Less]

Jython

Jython is a Java implementation of the Python programming 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 a very seamless and smooth integration with Java: from Python you have complete access to all Java ... [More] libraries, can build applets, can integrate with Java beans, and can subclass Java classes in Python and vice versa. Like Python, and unlike Java, Jython can also be used interactively: just type some Jython code at the prompt and see the results immediately. [Less]

CLISP - an ANSI Common Lisp

GNU CLISP is an ANSI Common Lisp implementation with an interpreter, compiler, debugger, object system (CLOS, MOP), sockets, fast bignums, arbitrary precision floats, and foreign language interface which runs on most UNIXes and Win32.

Boo Programming Language

A wrist-friendly language targeting the Common Language Runtime (.NET / Mono) with an extensible compiler pipeline, a syntax reminiscent of Python, and many other features (like type inference, syntactic macros, etc.)

Squeak

Squeak is a modern, open source full-featured implementation of the powerful Smalltalk programming language and environment. Squeak is highly-portable - even its virtual machine is written entirely in Smalltalk making it easy to debug, analyze, and change. Squeak is the vehicle for a wide range of ... [More] projects from multimedia applications, educational platforms to commercial web application development. [Less]

Rubinius

Rubinius is an execution environment for the Ruby programming language. It is comprised of three major pieces: a compiler, a 'kernel' (otherwise known as the Ruby Core Library), and a virtual machine. The project's goal is to create a top-of-the-line Ruby implementation.

Racket

Programming language suitable for implementation tasks ranging from scripting to application development, and supporting the creation of new programming languages. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, and various other tools.
