Open Source Scheme Software for Windows

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.

Schism is an experimental compiler that translates Scheme programs into WebAssembly, allowing Scheme code to execute in both browser environments and server platforms like Node.js. Developed initially by Google researchers, the project was designed to explore the intersection of functional programming and WebAssembly’s low-level efficiency. Schism supports a subset of the R6RS Scheme standard and is self-hosting, meaning that the compiler itself is written in and compiled by Schism. Its architecture demonstrates advanced compiler design techniques such as staged compilation and snapshot-based bootstrapping. The project focuses on leveraging WebAssembly’s experimental capabilities, including reference types and tail calls, to test the limits of language portability and runtime performance. Though no longer actively maintained, Schism remains a valuable example of how high-level languages can be mapped to WebAssembly and offers insights into language implementation.

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.

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.

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

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.

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

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.

Niche website for webmasters promoting adult companies through referrals, Flat File RSS Archives, make money through webmaster referrals and from the regular surfer. New programs are added all the time so please use this to your advantage.

A set of Eclipse plugins for the Scheme programming language. Features a powerful, fully extensible S-expression-based editor. Integrates seamlessly with any Scheme interpreter.

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).

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.

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.

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.

Functional XML parsing framework: SAX/DOM and SXML parsers with support for XML Namespaces and validation. Related to SSAX are SXPath queries and SXML transformations, with applications to XML/HTML authoring and literate Scheme and XML programming.

In this project we aim to develop scheme libraries for developing various web applications (especially servlets and xml-based web services). Our approach is to use jscheme (an open source implementation of scheme in Java) as the core language which allow

Useful libraries for PLT Scheme, biased towards development tools.

A declarative logic programming system with first-class relations embedded in a pure functional subset of Scheme. The system has true unions, fair scheduling, lexically-scoped logical variables, set-theoretical semantics, high performance without cuts

This project exists as an archive for Crack.com's 3D FPS/Strategy/RPG game called Golgotha. Shortly after C.c's demise, a small band of developers attempted to bring the game to completion. Here lies their code too.

Development of the Italian Version of FESTIVAL Text to Speech synthesis system

Kawa is a full Scheme implementation. It implements almost all of R5RS (for exceptions see Restrictions), plus some extensions.

A GTK-server based GUI for Bigloo Scheme; a Windows distribution for both Bigloo, and GTK2. Tutorials on how to call GTK2 procedures from Scheme. A simple GUI for OCaml. It offers two kinds of widgets, to wit, buttons and an Emacs like mini-editor.

MOSREF provides a secure, portable and dynamic environment for the development, deployment and management of network and host security auditing tools.
