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>).

The TclPro tool set includes a graphical debugger, a static code checker, a wrapper to generate stand-alone executables, a "compiler" that writes out Tcl byte codes, and a loader that reads byte codes.

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)

This is a project to develop tools for the MOUSE programming language and to encourage its use as an experimental and teaching language.

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)

UPS is a source level C, C++ and Fortran debugger with an X windows interface. It's a very light debugger, but is quite efficient and works well. An ANSI compliant C interpreter is included.

A FrameWork to develop Pascal Applications. This includes Integrated Development Environment (Rapid Application Development -RAD-), Virtual Machine, Web Services (Pascal Server Pages -PSP-) and too many tools

ruby's expressivity together with static typing

Parsing, interpreting, checking and profiling C application (ISO/IEC 9899:1999 (E))

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".

Nak is a video game compiler, based on lua. With his dll system, you can made your own functions for nak. For now, only 2d system will be added.
