Open Source Scheme Software

GnuCash is a personal and small-business finance manager with a check-book like register GUI to enter and track bank accounts, stocks, income and expenses. GnuCash is designed to be simple and easy to use but still based on formal accounting principles.

An implementation of DSSSL, a style language to format SGML or XML documents. OpenJade contains backends for various formats (RTF, HTML, TeX, MIF, SGML2SGML, and FOT). This project also maintains OpenSP.

Repository for porting and creating GPL licensed scripts for the latest GIMP. At the moment that is 2.6. In the future this effort can be directed towards newer versions easily while still providing a source for older versions of scripts.

Chez Scheme is both a programming language and an implementation of that language, with supporting tools and documentation. As a superset of the language described in the Revised6 Report on the Algorithmic Language Scheme (R6RS), Chez Scheme supports all standard features of Scheme, including first-class procedures, proper treatment of tail calls, continuations, user-defined records, libraries, exceptions, and hygienic macro expansion. The Chez Scheme implementation consists of a compiler, run-time system, and programming environment. Although an interpreter is available, all code is compiled by default. Source code is compiled on-the-fly when loaded from a source file or entered via the shell. A source file can also be precompiled into a stored binary form and automatically recompiled when its dependencies change. Whether compiling on the fly or precompiling, the compiler produces optimized machine code, with some optimization across separately compiled library boundaries.

The Linux GPIB Package is a support package for GPIB (IEEE 488.2) hardware. The package contains a development environment consisting of a GPIB library written in C, kernel driver modules, and bindings for several other languages.

EDE is fast desktop environment with familiar look and feel. It should work fine on slower computers too.

TinyScheme is a Scheme interpreter that can execute Scheme code but is also suitable for embedding in programs. The goal is to keep the interpreter small while providing as much compatability with Scheme standards as possible.

Snd is a sound editor.

A quantitative finance C++ library for modeling, pricing, trading, and risk management in real-life. A cross-platform free/open-source tool for derivatives and financial engineering.

Gauche is an R7RS Scheme implementation aimed to be a handy tool for daily works. Quick startup, built-in system interface and native multilingual support are some of the goals.

A collection of libraries for Bigloo Scheme compiler.

Relax NG Compact Syntax validator

This project is for maintaining a linux system that concentrates on math, logic, and geometry related softwares.

A Unix shell embedded in Scheme.

Ksi is a portable, embeddable Scheme implementation written in C.

WiLiKi is yet another Wiki-clone suitable for intra-net collaborative work in multilingual environment. The features include multiple back-end databases, permission and version control, and easy access from other programs.

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

This is a resurrection of Matthias Blume's VSCM Scheme implementation.

Trackballs is a game for linux in which you steer a marble ball through tracks of varying difficulty. The game is loosely based on Marable Madness and features 3D graphics, an integerated level editor and highquality soundeffects and background music.

An implementation of the language described in "Karel the Robot: A Gentle Introduction to The Art of Programming" by Richard Pattis et al. Both Java and C/Unix versions are available.

AutoGen is designed to generate text files containing repetitive text with varied substitutions. Its goal is to simplify the maintenance of programs that contain large amounts of repetitious text, especially when needed in parallel tables.

REGBLOOD stands for REactive Game with BigLOO in 3D. The goal of this project is to add multimedia bindings to the Bigloo scheme compiler. It provides glue for schemers to use SDL and OpenGL, as well as a general 3D engine. This game is a snooker.

Haxima is an Ultima-like game engine (2D tile graphics) with combat, magic, NPC AI, an embedded scripting language, and in-game editing.

Logprocessor is a tool for analyzing log files in a rigorous and reliable way. You write a command file and the log file can be run though the tool resulting in pass/fail.

An interpreter for the Right-reference Pedagogic Algorithmic Language.
