JPype is an effort to allow python programs full access to java class libraries. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both Virtual Machines. Maintenance and evolution of the project has moved! please see http://www.jpype.org for the latest version

The Portable Forth Environment implements the ANSI Forth Standard, it is fully written in C, the newer version has a module concept, and it is fully multithreaded. Autoconf used. Tested in embedded environments.

OpenGLide is a Glide to OpenGL wrapper. It emulates a Voodoo board so you can run old Windows Glide games by translating Glide calls into OpenGL. The CVS code moved to https://github.com/fcbarros/openglide.

SciTECO is an interactive TECO dialect, similar to Video TECO. It also adds features from classic TECO-11, as well as unique new ideas. Project development takes place here: https://git.fmsbw.de/sciteco The download archive is mirrored at Sourceforge, but for nightly builds check out: https://sciteco.fmsbw.de/downloads/nightly/

GLBCC is a front-end to the GNU Compiler Collection. GLBCC adds Liberty Basic to the GCC language collection so that Liberty Basic code can be compiled directly to an executable. Since GLBCC uses GCC, the object files can also be linked with object file

A easy basic in order to make games in 2d style amos for linux and windows The basic it comprises a module runtime, ide examples and games.

Joost is a Java implementation of the Streaming Transformation for XML (STX) language (see http://stx.sourceforge.net/)

DDay.iCal is an iCal (RFC 5545) class library for .NET 2.0 and above, Silverlight. It aims at being as RFC 5545 compliant as possible, while targeting compatibility with popular calendaring applications, like Apple iCal, Outlook 2007, etc.

Lsl Plus is an edit/compile/test environment for the Linden Scripting Language (LSL), implemented as an Eclipse plug-in.

Mutabor is a Program that allows performing and composing microtonal music using a normal MIDI keybord. But it's powerful description language is intended to allow permanent retunings and tuning logics in to describ, what's actually goes on.

Pika is a fast, lightweight, dynamic multi-paradigm programming language. Its list of features includes: First Class Functions, Closures, Lexical Scoping, Optimized Tail Calls, Classes, Cooperative threads, Packages, Properties and Exceptions.

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

TclRAL is an implementation of the Relational Algebra as an extension of the Tcl Language. TclRAL is coded in "C" and provides new data types that are integrated into Tcl's internal object system. Raloo is a Tcl package that combines TclRAL and TclOO. Please note that the source code for this project has been moved to a Fossil repository that can be accessed from the menu bar.

A Logo interpreter and programming environment specialized for schools. It is a revised version of XLogo, published on http://xlogo.tuxfamily.org/. The Logo dialect is almost the same as Xlogo's, but some Logo commands were reimplemented to fit with the new programming environment and workspace. Some commands which were buggy in the original XLogo have been fixed. The interpreter works now more efficient due to the usage of more suitable data structures. The output of turtle graphics is now smoother and more appealing due to different rendering settings. Various features have been added to support better user experience and satisfaction in schools. @Translations: The new GUI parts are available in * English * German * French * Italian If you would like to make the application available in your language and if you would like to contribute, please contact us. * * * * * * * * * * * News * * * * * * * * * * The X4S Manual is now available on the files page.

TBasic is an implementation of a minimalist BASIC (based on the Tiny Basic specification but with a few significant additions) in the C++ language. It was written for fun, as a project to create a functional language interpreter from scratch and to be potentially used as a lightweight scripting language (it can either be used as a classic command line BASIC interpreter or as a class that allows a C++ programs to load and run basic programs, register custom basic commands and interact with basic variables).

FOML is an expressive logic rule language that supports object modeling, analysis, and inference. It naturally supports model-level activities, such as constraints (extending UML diagrams), dynamic compositional modeling, analysis and reasoning about models, model testing, design pattern modeling, specification of Domain Specific Modeling Languages, and meta-modeling. FOML can reason about: 1. The model meta-data (meta-model level reasoning, or syntax reasoning) 2. Data level: reason about a model and its data (instance model, i.e., diagram) FOML is built as a semantic layer on top of PathLP - a compact logic rule language of guarded path expressions, an adaptation of a subset of F-logic.

A runtime parser generator library, generates parsers for context-free grammars. Parsing scripting languages and communication protocol messages are typical use cases. The library is written in straight C++ and requires STL. Clean, correct, efficient.

ADP (Another Data Processor) is a programing language that is designed for Web database programing. It is a scripting language and a lightweight programming language in which it is possible to mix SQL easily. It is easy to install. ADP is base on Prolog. But ADP uses only the backtrack and unification. The syntax is original and likes a another scripting language, supports method call.
