Open Source Java Interpreters

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

Emulator of the ancient 8 bit microprocessor ISP-8A 500D/600D or more common "SC/MP" from National Semiconductor. The download contains all sources plus an executable Java Jar file to start right away. Some SC/MP hex dump examples are provided in directory "/etc" as well. The download also contains unit tests and some helping documentation (also in /etc). You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers. The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old. Have fun, Theo Heinrichs

Blocks is a block-oriented graphical programming language. Programming is simply a matter of dragging and dropping blocks. Blocks can be used as an education language, as an extension language for Java applications or as an autonomous script language.

Erc is an interpreted link-oriented language. Majic is a java-based interpreter for Erc, and Majicc is a c++ based compiler for Erc which uses the Majic libraries.

JLisa, \"Java Lisp-based Intelligent Software Agents\", is based on Lisa, http://lisa.sourceforge.net/, a production rule system similar to Jess. It runs in java through ABL, armed-bear Lisp, http://www.armedbear.org.

Junicon is a Java-based implementation of Unicon, a very high level object-oriented goal-directed programming language that lives at Unicon.org. Junicon features seamless Java object access, interactive interpretation, and numerous cleanups and enhancements while retaining Unicon's core expression-evaluation semantics. Please see the Junicon Project Web Site for publications about Junicon.

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

jAMAL is a Java-based reimplementation of the AMOS Animation Language (AMAL).

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.

Am implementation of ISO Prolog standard as Java library. We have moved to savannah: https://savannah.gnu.org/projects/gnuprologjava/

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

Locos is an object oriented framework for building parsers and other language processing tools.

The MCAPL Project provides a tool for prototyping BDI agent programming languages and model checking programs written in these languages via an interface to the JavaPathfinder model checker.

Introspect on running programme, view and alter object fields and methods. Edit the code of any method at runtime; apply the changes to any combination of objects, such as an array, or a complete class. Complete rewrite underway available Jan 2007.

Simple V converts FHX files created by the Delta V programming laguage into easily readable charts. Allows reviewing of code without havaing the Delta V ide installed.

Agent Factory is an open and extensible framework for developing and deploying agent systems that provides a FIPA-based distributed Run-Time Environment that supports the deployment of diverse agent types, ranging from bespoke, reactive to deliberative.

ADeLa is a scripting language with a python-like syntax, designed for easy embedding into java applications to drive all or part of the application logic. ADeLa scripts run in a sandbox into which only the desired functionality is exported.

ActivityScript takes an activity diagram (created with a UML tool) and executes it's contents. The content of Activity boxes are executed, the Guards of a Decision box are evaluated to control program flow and Fork boxes initiate new threads.

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.

Simple to use expression engine supporting an own expression language, including parser and expression evaluation.

BigNumbers provides the tools to make (normally unreadable) BigDecimal calculations in Java easy. It allows you to express decimal calculations in a friendly way; BigNumbers will in turn take your expressions and turn them into BigDecimal calculations.

CDCL (Cascading Disclosure-Control Language) is a simple, transparent, high-confidence mechanism for declaring rules of disclosure. It is a language and framework built expressly for item-level disclosure control.

Cigol (logic, spelled backwards) is a deductive logic solver. It can be embedded inside a parent program or used from the command line. It has absolutely no relationship to Tom Mitchell's book on Machine Learning.

The Cocoon Adaption Kit is a NetKernel module which enables the use of Cocoon Components (Generators, Transformers, Serializer, Actions) from within the NetKernel XML Application Server.

Metaprogramming: proof of the concept.
