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.

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.

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

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.

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).

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)

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.

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

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.

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.

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.

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.

A Unix shell embedded in Scheme.

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

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

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.

STklos is an efficient Scheme System providing a powerful Object System

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
