Home of the Open Object Rexx Project. ooRexx is the open source version of IBM's Object REXX Interpreter. It is upwardly compatible with classic REXX and will execute classic REXX programs unchanged. The project is managed by the Rexx Language Association.

A gdb-like debugger for bash

PC-BASIC is a free, cross-platform interpreter for GW-BASIC, BASICA, PCjr Cartridge Basic and Tandy 1000 GWBASIC. -- This page is an archive and hosts the legacy version 1.2 of PC-BASIC only. -- For documentation and the latest releases, please see the official homepage: www.pc-basic.org Four source code, discussions and to report bugs please see the GitHub project page https://github.com/robhagemans/pcbasic

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.

The MDK provides a simulator of D. Knuth's MIX computer, and a development environment to write, run and debug MIXAL programs on it.

Pyexpander is a powerful macro processor based on python. Instead of simple macro replacement it offers evaluation of arbitrary python expressions and execution of python code. Pyexpander is Turing Complete.

CJKPython is internationalization and localization efforts for Chinese, Japanese and Korean environments on Python.

BASIC interpreter for the 16bit PIC microcontroller 24FJ64GA002. The interpreter runs on the chip only, no compiler/tokenizer is needed. Communication with PC is done by USB-to-serial converter cable.

A Zilog Z80 simulator, debugger and profiler tailored for ZX Spectrum development (but generic enough to be used with other platforms)

The Vortex project consists of 2 things. The Vortex OS and VParse. The OS is multitasking and handles a lot of features. VParse is a stand alone Vertex2 parser. Vertex is vortex's scripting language. Pre 0.7 is QBasic and 0.7 is C++.

Terminal-BASIC is a BASIC-like language interpreter, works on a set of single board embedded systems (i.e. famous AVR uc based boards). Terminal-BASIC: * suports real numbers, multidimensional arrays and Darthmouth BASIC-style matrix operations; * written in C++11; * has modular structure (can save uc storage, instantiating only used modules); * works through different i/o devices, using vt100 commands; * on systems with multiple i/O devices can work as simple time-sharing system; * static Linux build for playing and debug;

several vaguely related projects worked on by me: a 3d engine with a javascript-like scripting language (pdsys); an older scheme dialect (vmsys); ... (2009-04-28: I have been gone for years, may try to put up some newer stuff...).

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.

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.

TclTrf is an extension library to the script language tcl, as created by John Ousterhout. It extends the language at the C-and Tcl-with ``transformer''-commands to encode and compress data. Based on the stacked channels of the tcl core (ability inter

TinyTcl is a tiny version of Tcl, for small footprint machines and embeddable/rommable applications. It is derived from Tcl 6.7 and compiles to less than 60K, 10X smaller than Tcl 7 and Tcl 8.

kissme is a free (GPLed) Java Virtual Machine. It is being developed on GNU/Linux and can run console java applications. kissme is to be used with the GNU Classpath java class library. kissme also provides support for orthogonally persistent java.

Erc is an interpreted link-oriented language. Majic is a java-based interpreter for Erc, and Majicc is a c++ based compiler for Erc which uses the Majic libraries.

Sarien is a portable implementation of the Sierra On-Line Adventure Game Interpreter (AGI), and is able to run games such as Leisure Suit Larry in the Land of the Lounge Lizards and Space Quest I and II.

Provides a remotely (or locally) scriptable JVM along with a perl & C client

Safe Lua is a variant of Lua tailored for advanced sandboxing.
