Open Source Python Interpreters

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.

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

Powerful command line and configuration file parsing for C++, Python, Ruby and Java (others to come). This tool provides many features, such as separate treatment for options, variables, and flags, unrecognized object detection, prefixes and much more.

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

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.

HSPL is Human Speakable Programming Language, allowing for communication between human-to-computer and human-to-human in the same language. This project has moved to http://sourceforge.net/p/spel We are currently working on human-to-computer programming-language with mostly English base vocabulary. Though once we have that, we plan to add support for other world Languages, including Chinese, Spanish, Russian, Arabic, Hindi, among others. Eventually HSPL shall be the foundation of GIOS the General Intelligence Operating System. Which is an open source operating system, that can be used for intelligent robots, computers and technological host-bodies. Regularly post on blog about HSPL at http://weyounet.info/?s=hspl

ACDK - Artefaktur Component Development Kit - is a platform independent C++-framework similar to Java or C#/.NET for generating distributed and scriptable components and applications.

Broccoli is a dynamically-typed, multi-paradigm programming language.

LucidEngine is a simple layer over MIDP compatible phones that will let you write simple and old fashioned games using a specific language. Every game you'll develop will basically work on all the devices (even not phones) LucidEngine as been ported.

An XML-based MP3R framework for the web applications Model - Process - 3R (Role, oRgnization, Responsibility)

Multi-language library to deal with multimethod dispatch, disambiguation and type-checking using dispatch tables. This approach yields fast dispatch in constant-time and greatly helps resolving ambiguities.

PyREXX is a interprocess messaging server for routing remote prodecure calls using xml-based messages (Jabber, XML-RPC, etc), which will allow programs to interact more easily.

idyuts is \"I Dare You to Use This Shell\"; a pre-hibernate approach to replacing an ORM written with jython functors into a pure-Java language command pattern. The \"pipeline codegen artifacts\" are simple IoC templates, and trivial to adapt

An IRC client that uses Tcl for not only the scripting, but also the "glue" at the C level for how all the parts of the application fit together.

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

Administrative WebSphere library. Designed as a foundation library (providing a wsadmin.sh wrapper) following Object Oriented approach for WebSphere administrators who are used to develop Python scripts to do WebSphere adrministrative tasks.

jp scratchpad is an interactive execution enviroment for jpython, inspired from Mathematica notebooks.
