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.

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.

Racket is a general-purpose programming language and an ecosystem for language-oriented programming. This repository holds the source code for the core of Racket plus some related packages. The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization. Racket programmers typically program with functions, records, objects, exceptions, regular expressions, modules, and threads. That is, instead of a “minimalist” language, which is the way that Scheme is often described, Racket offers a rich language with an extensive set of libraries and tools. Libraries are not restricted to exporting values, such as functions; they can also define new syntactic forms. In this sense, Racket isn’t exactly a language at all; it’s more of an idea for how to structure a language so that you can extend it or create entirely new languages.

Snd is a sound editor.

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

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.

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.

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

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

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

GnoTime (formerly GTT, the Gnome Time Tracker) is a desktop utility for tracking the amount of time spent on projects, keeping a to-do list, maintaining a diary, and generating reports and invoices based on that time.

SISC is an extensible Java based interpreter of the algorithmic language Scheme. SISC uses modern interpretation techniques, and handily outperforms all existing Java interpreters (often by more than an order of magnitude).

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.

ECB is a file/code browser for Emacs. It can be used to browse any type of file and supports parsing of Java, C, C++, Elisp and some other code like perl, TeX, LaTeX. All browsing windows are within one frame and they are deletion-protected (eg by C-x 1)

Scwm is the Scheme Configurable/Constraints Window Manager, a window manager with a powerful dynamic configuration language based on Guile Scheme. Scwm has many, many advanced features, often implemented in the configuration language itself.

SketchyLISP is a highly portable, embeddable interpreter for purely applicative Scheme.

This is a modified version of the original Mini-scheme interpreter from Atsushi Moriwaki. It has been modified by Jacques Bailhache. New features have been added such as calls to Windows API functions. It can run on Linux, Windows and Windows Mobile.

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

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.

Relax NG Compact Syntax validator

Useful libraries for PLT Scheme, biased towards development tools.

This project is dedicated to developing more readable format(s) for Lisp-based languages (such as Common Lisp and Scheme) and implementing those formats (readers, pretty-printers, editor macros, etc.). MIT license preferred, to spread them widely.

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.
