Open Source Scheme Software Development Software

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.

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.

FEAR is a development kit helping software engineers create advanced artificial intelligence in synthetic characters with simplicity and efficiency. The project includes reusable AI components, portable framework and interfaces to realtime 3D games.

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

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).

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

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.

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.

Useful libraries for PLT Scheme, biased towards development tools.

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...).

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.

SISCweb is a framework to facilitate writing stateful Scheme web applications in a J2EE environment. An example WAR file ready for use is provided. Try it today!

STklos is an efficient Scheme System providing a powerful Object System

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

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.

Glimmer is a code editor for GNOME, using Python as a scripting language for extending it's capabilities.

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)

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

Wisp is a small Scheme-like language designed to be easily used in various structured data processing tools. The accent is on simplicity, automatical generatibility, and efficiency. (Currently on long hiatus. Gauche has similar goals and is maturer.)

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

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

FramerD is a distributed semi-structured object database originally developed at MIT. It provides an internationalized Scheme-based scripting language, built-in text analysis tools, and special support for web scripting.

A simple interface to SQL databases (currently MySQL and PostgreSQL) from Guile.

An optimising compiler for the R5RS Scheme language, written in R5RS Scheme, compiling to ANSI C, supporting Unix-like platforms, performing whole-program analysis and online partial evaluation.

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