Open Source Interpreters

PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You'll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. As an example, libraries like PyQt, Django or matplotlib are fully supported, without having to handle plugins or external data files manually.

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

Brainfuck Center is an IDE and compiler for your Brainfuck scripts. It includes a full debugger with step-by-step debugging and much more. MDI window!

This project originally was about a megaman clone called "Game Developer Man". Game Developer Man, the game, has long since tanked. However this project has moved on to the KRGP.

Ironseed is a crossplatform binary version-compatible programming language, an answer to Microsoft COM technology which also does not have such limitations.

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)

The aim of the project is to provide short description of many programming languages, dialects, IDEs, etc. with sample programs (realizations of common algorithms like 'hello, world', 'dot product', 'quine program').

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".

PLT Spy is a Python to Scheme translator.

A Portable Forth. It is aimed to be interpreted, or compiled to various architectures and VMs.

Everything related to forth programming that has been discussed on the comp.lang.forth usenet newsgroup. The site is dedicated towards improving portability between forth implementations, providing surveys, example implementations, and library modules.
