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.

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 Though no longer actively maintained, Schism remains a valuable example of how high-level languages can be mapped to WebAssembly and offers insights into language implementation.

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

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.

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.

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.

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

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.

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).

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.

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

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.

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

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.

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.

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

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

STklos is an efficient Scheme System providing a powerful Object System

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.

A Windows native distribution of Bigloo, a Scheme system that includes an optimizing compiler generating C code, Java classes and .NET CIL files as well as an interpreter.

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)

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.

RScheme is a Scheme implementation with a reflective object system, operating system services, modules, threads, many other system programming features (including the ability to integrate with and compile to C code), and a wealth of useful extensions.

`Autotemplate' is a document's templates library manager. Users can use, and overload the default templates library ; also easely create new templates. A template can here be define as a specific files hierarchy, defined with rules and parameters.
