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.

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

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.

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.

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

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.

A programming language embedded in PLT Scheme that supports advanced separation of concerns using predicate dispatching.

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

A Unix shell embedded in Scheme.

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.

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.

Metaprogramming: proof of the concept.

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.

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.

JSchemePlus is an hack of Jscheme 1.4 by Peter Norvig. It allows to redistribute a script in an executable JAR file of only ~40K and implements all of R4RS with a lot of additional functions, like: (execute command) (random) (sequence from up-to step) (split list element) (string-split string sub-string) (read-all-from-file file) (write-to-file file data) (file-size file) etc... For the complete list read the HELP file or type (help). JSchemePlus needs only the Java Virtual Machine (version 6 or higher) that, in the case, is very easy to download and install.

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

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

Portable Scheme interface to the Tk graphical user interface toolkit

STklos is an efficient Scheme System providing a powerful Object System

Water: a fast, secure, dynamic OO language and database. Water is an all-purpose language (and meta-language) that runs Web applications in the browser or server-side. Water is compatible with .NET, Java, and C on Windows, Linux and Mac OS X system.

Waxeye is a parser generator based on parsing expression grammars (PEGs). It supports C, Java, Javascript, Python, Ruby and Scheme.
