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.

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

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.

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.

Kirisurf is an open-source internet traffic integrity protector based on SSH and SSL, with many innovations in traffic obfuscation and server distribution. It can be safely and reliably used to circumvent censorship in China. Please visit our website for downloads, as SourceForge downloads are packet-scanned in China and may be unreliable and/or hijacked.

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.

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.

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

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

Computer-assisted transcription prototype for handwritten text in old documents

RYUON : many-particle simulation suite

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.

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

Yes, Scheme really is a portable language. S2 proves it. S2 compiles various dialects to R5RS, and can bootstrap under four different dialects

Luna is a Scheme compiler and run time environment for .NET - it is written in C# and Scheme, and provides a useful superset of the R5RS standard.

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).

Elementals. Elementals are small creatures that have dedicated purpose.

MScheme is a Scheme interpreter implemented in Java. The project goals are to fully comply with the "Revised^5 Report on Scheme" and a clean and modular design.

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 real-time strategy game, with multiplayer support, that pits you between diplomacy and war. It is a combination of simcity and civilization, but in a much more exciting fashion.
