Open Source C Interpreters

MinGW: A native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All of MinGW's software will execute on the 64bit Windows platforms.

Tool Command Language (Tcl) is an interpreted language and very portable interpreter for that language. Tcl is embeddable and extensible, and has been widely used since its creation in 1988 by John Ousterhout. Bug reports to http://core.tcl.tk/tcl/ Follow code development at http://core.tcl.tk/tcl/

CLIPS is a forward-chaining rule-based programming language written in C that also provides procedural and object-oriented programming facilities.

CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.

An implementation of the the ANSI Standard REXX Programming Language, available for most operating systems.

GNU Prolog is a free implementation (under GPL) of the logic programming language PROLOG. It can compile to native machine code which is extremely fast in execution. Another feature is the included constraint solver.

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.

This project will allow a group of people to develop the Euphoria programming language: interpreter, translator, binder, documentation etc. For more information visit https://openeuphoria.org

The Python programming language, an object-oriented scripting and rapid application development language. You can download it from http://www.python.org/download

ICI is a general purpose interpretive programming language that has dynamic typing and flexible data types with the flow control constructs and operators of C.

Extends Tcl by providing new operating system interface commands, extended file control, scanning and status commands and many others. Considered by many to be a must-have for large Tcl apps.

LambdaMOO is a network-accessible, multi-user, programmable, interactive system well-suited to the construction of text-based adventure games, conferencing systems, and other collaborative software.

Loglan'82 is a programming language conceived for object and distributed programming. It has many features that make Loglan'82 a tool surpassing other programming languages: * It enjoys a unique safe and efficient system of managing objects, see [[Safe dealocation]], * It offers modules of classes (__class__), moreover it allows to declare modules of cooperating objects i.e. **coroutines** and modules of threads ('''process'''). One can create not only objects of classes, but also objects of coroutines with their ''fibres'' and objects of processes, aka agents with their *threads*. * Virtual machines of Loglan may connect (through internet) in a virtual, multiprocesorr computer.This allows to distribute a computation of a program between processors in a controlled way. * Objects of processes (agents) can be alocated on different nodes of a network of virtual machines or on the same machine.

Ficl is a lightweight, embeddable scripting language designed to be incorporated into other programs, and especially embedded systems that may have memory and OS constraints. Applications include scripting, hardware bring-up, rapid prototyping, and system extensions. Unlike Lua or Python, Ficl acts as a component of your system - you feed it stuff to do, it does the stuff, and comes back to you for more. You can export compiled code to Ficl, execute Ficl code from your compiled code, or interact. Your choice.

MiniBasic is a small but usable Basic interpreter. It is written in pure ANSI C, so it should be easy to get up and running in almost any environment. It has been used for PIC32 electronics projects, as an embedded scripting language, and as a teaching aid. There's an associated book, and full documentation and sample programs online (go to the project's web pages). It's designed to be easy to modify, to use the code as the basis for your own interpreter.

SableVM is a clean-room, highly portable and efficient Java virtual machine. Its goals are to be reasonably small, fast, and compliant with the various specifications (JVM specification, JNI, invocation interface, etc.).

Xconq is an engine for turn-based strategy games. Variety of game genres run under Xconq: historical, sci-fi, fantasy, and modern. AIs. Network games. Multiple UIs and platforms. Easy-to-learn game design language. Large games library available

JACL is an interpreted language for creating interactive fiction and other turn-based games that can be played on the desktop or over the web. This project is now hosted at Google Code. Please visit http://code.google.com/p/jacl/ for latest source co

A project devoted to porting existing software, and writing new software for the Amiga Research Operating System. The website, http://www.aros-stuff.tk/, contains more information, and is more frequently updated.

Adventure Definition Langage (ADL) - a language used to create text adventures similar to Zork and other Infocom games.

The main goal of BASIC foundry on SourceForge is to gather all developers that works something related to BASIC programming language in order to help creation of fast, stable, cross-platform, OPEN SOURCE BASIC compiler.

A general purpose, object-oriented script language that compiles into code for a register based virtual machine. The language is quite similar to object-oriented high-level languages like Java and C#. The library is entirely self-sufficient and ANSI C compliant. It's main purpose is to be embedded in any application to allow automation of that application through scripting. An integrated C++ binding code generator allows you to create bindings for your application's classes in seconds. The integrated HTML documentation generator allows you to create documentation for your native bindings in seconds. The project is released under the zlib/libpng license. It has been in development for over 10 years and offers some powerful features. Extensive information, documentation, articles and code examples can be found at the developer blog.

Object Tree, Virtual Machine and Compiler for Concatenative Languages, in a shared library - [This project is obsolete, and has been superseeded by the XCL suit, available at http://www.varkhan.net/software/xcl]

A powerful interpreted language with simple compiler for Windows 7 to create apps for graphics, image acquisition, processing and advanced analysis. Includes 800+ commands, help, simple development studio, plug-in API and Debugger window.

GCI is the Generic Call Interface for REXX interpreters. GCI allows REXX programmers access to all shared libraries (aka DLLs) where there are no REXX-specific wrappers.
