Open Source Interpreters

A gdb-like debugger for bash

== This project has been renamed to slang-lang/slang and moved to Github. == ObjectiveScript is an object orientated scripting language that tries to combine the speed of scripting with an object orientated syntax similar to Java and C++. The language offers native data types like bool, double, float, int and string as well as user defined object types and a system library with data types similar to the Java boxed types like Integer and String. Collections like List, Map, etc. can be used with object and value types and can also be used as raw types (i.e. List == List<Object>).

Jasmin is an interpreter for the x86 assembly language with a full-featured development environment aimed for educational purposes.

A Zilog Z80 simulator, debugger and profiler tailored for ZX Spectrum development (but generic enough to be used with other platforms)

ObjectScript is a general purpose object-oriented programming language. It is designed to be simple to learn, easy to use, yet still powerful, combining the convenience of an interactive interpreter with many of the features of Java

The XPS is a scalable platform for meta-programming and domain engineering. It provides a virtual machine, compiler, and runtime library that make it possible to efficiently develop, debug, and run programs based on XPL (eXtensible Programming Language)

ASTRA is an implementation of AgentSpeak(TR) that has built in support for the CArTaGo and EIS environment models. Support for conversation management is provided in the form of the ACRE conversation manager.

Avrora is a suite of tools for analyzing and debugging programs for AVR microcontrollers. It has support for a sensor platforms such as Mica2 and MicaZ, allowing wireless network simulation and allows dynamic instrumentation and static analysis.

ESELC is a interpreter for the Easy Stack Environment Language (ESEL). It is written in ISO C++.

LOLCode IDE plugin for Eclipse. LOLCode is a new humorous language designed to teach those new to programming, and to be enjoyed by the rest of us. This plugin does syntax highlighting, code folding, debugging and content assistance.

ExpressionJ is a Java library allowing to interpret simple numeric expressions, which may be used in all applications which have to combine numeric values, but do not want to use full-blown scripting languages.

GLfunge98 - OpenGL-based *NIX/Win32-interpreter for Befunge93/Funge98 with dynamic extensions.

We extend the Eclipse IDE with tools for development in Haskell, a functional programming language, providing support for a wide range of tools (compilers, interpreters, doc tools etc.) in a coherent, convenient and configurable environment.

An official experimental fork of Python's integrated development environment IDLE. Worthwhile and successful changes and additions will go back into the Python distribution's IDLE at some later stage. There is no spanish inquisition.

Java-program to read, modify and execute class-files. a real java VM written in java or a decompiler for class-files is possible (and partially working)

JavaCET is an API wrote in Java that allows to analyze Java source code and libraries, and control its execution and its trace in an integrated and comprehensible object-oriented way. It allows backwards execution.

The Language Processing Agency provides agents and an agent-oriented infrastructure for developing language processors in .NET. Typical language processors are transformation tools, extraction tools, language interpreters, etc.

Language Prototyping System

Longenis is a simple, powerful object-oriented scripting language incoporating elements of Python, Tcl, Java, and Lua. It is designed to be light, clean, elegant, and cross-platform.

LLVM is a unique compiler infrastructure designed for the optimization of programs from arbitrary programming languages. Compilation in C and C++ programs is supported using a parser based on GCC 3.4. Backends exist for X86, Sparc, PowerPC and "C".

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.

NG-BASIC is an experimental BASIC language that can be both interpreted within an Integrated Development Environment (and debugged through that same environment) as well as compiled to a native executable. The goal of this project is to reproduce an environment similar to QuickBASIC 4.5 for modern operating systems and for BASIC enthusiasts.

Piet++ is the foremost interpreter for Piet++, an extension and expansion over the original Piet programming language.

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.

Struts Config Reloader is developed to suppot the reload of struts1 config.Now this tools is support for reloading struts-config.xml and tiles,message resouces that defined in struts-config.xml .
