ANS Forth for Win32 and Linux/x86 (used to compile the following SF projects: acWEB, acFTP, acFreeProxy, acSMTP, Forth-Script)

Gentee is a friendly full-scale and free programming language. It is easy-to-master and can be a reliable assistant in your everyday work. Software developers can easily use it in their applications.

Open Basic (OB) is an implementation of BASIC programming language interpreter. OB is developed for embedding into user application as scripting language. OB is distributed as source code under MIT License.

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

This tutorial demonstrates how easy it is to accomplish real world programming goals with Rebol. The text aims to teach average users to program computers to do useful things, without the long and difficult learning curve imposed by other languages.

C-smile OOL is a scripting language with C++-like grammar. It has compiler, VM running bytecodes and C++ extendible runtime. Intended to run in standlone and embedded mode.

Forpost is an embeddable, interpreted stack-based(Forth-like) language which has simple, compact and effective implementation in ANSI C. Main features: heterogeneous arrays, higher-order functions, program/data equivalence.

Gimp User Filter is a plugin for The Gimp (http://www.gimp.org/), originally written by Jens Restemeier back in 1997. This project is about maintaining the plugin, keeping it compatible with current versions of Gimp, and eventually extending its features

This project is the port of Lua programming language to Java platform. It contains the bytecode compiler and interpreter, that use the same bytecode format as the original version, and partially support standard Lua library.

Lemick is a project to make a programming language similar to those traditional Basic implementations but with all the attributes of the modern programming tool

MeMo (stands for Meta-Model) is planned as Generic Programming Language & IDE, as flexible & smart as it is possible for computer application, including adjustable syntax, algorithm reduction. Ideally, it has to contain AI for interacting with the user.

The project's aim is to build automated programming language translation system that will port program sources written in one language to other programming language(s).

QSP is a Interactive Fiction Development Toolkit, which combines editor and a player with detailed documentation.

Scheme runtime environment in Python.

Analyse and convert sources to trees of blocks. Project on FreePascal and Lazarus.

Scripting Tcl interface to Qt multiplatform library

Automata Based Programming Tool for implementing logic for J2SE, J2EE and Sybmian applications. Consists of Java FSM Framework and Eclipse Plugin parts. Plugin implements UML model editor, visual debugger, validator, compiler and interpreter for Eclipse

The UniXML library is intended to be an extremely portable XML DOM parser library, completely OS and C compiler independent.

nbasic - bytecode compiler+vm for middle level programming language, like basic. nbs - small and fast C-coded object orientated basic (compiler+vm) for embeded applications. Purpose: scripting support for C/C++ project.

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').
