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.

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.

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.

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.

Formicidae is the official simulator and visualizer for the Ant-Wars competitive programming site, written in Java and SISC. The site is hosted at www.ant-wars.net.

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...).

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.

Useful libraries for PLT Scheme, biased towards development tools.

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.

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)

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

A scheme (lisp) interpreter written in ARM assembly language (currently: Cortex-M4F,M7, Cortex-A5,A8,A9, Cortex-A53; previously:ARM7TDMI, ARM920T, Cortex-M3) for education, robotics, wearable devices. Tested on Allwinner A64, Amlogic S905, Atmel SAMA5D4, SAME70, SAMV71, NXP LPC4300, RT1050, iMX8M, Samsung S5P6818, ST STM32F4, STM32F7, and TI AM3359, OMAP3530, DM3730, OMAP4430, TM4C1294 chips (previously: NXP LPC-1300,1700,2000, ATMEL AT91SAM7, STM STR711, STR911, STM32, CIRRUS EP9302, LMI LM3S1968, TI OMAP).

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.

XSieve is an XML transformation language based on combination of XSLT (an XML transformation language) and Scheme (a Lisp dialect). XSieve is a powerful tool for complex data transformation tasks.

A framework for building distributed virtual reality applications, based on OpenGL|Performer(TM)

Elementals. Elementals are small creatures that have dedicated purpose.

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

A pattern matching library with a syntax similar to regular expressions, but more suited for morphological analysis. Differences from regex include: named variables, iterating over all possible matches, and extensible syntax.

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!

Spiritbot is a suite of tools designed for use in software-engineering, CodeGenUML includes an XMI/MOF/UML reader and exporter. An IRC ticker bot is also provided to aid in the development process.
