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.

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.

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.

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

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

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).

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.

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 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).

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

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)

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.

Momoko is a framework for developing distributed, multi-user, network-aware applications. It includes facilities for storing objects in a tree structure, a shell for manipulating the object database, orthogonal persistence, scripting support, and a trans

An interpreter for the Right-reference Pedagogic Algorithmic Language.

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

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

A Unix shell embedded in 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.

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.

text-template is a small text template library written in scheme.

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

Miscellaneous modules for guile, such as a reader for regex literals, "join" like perl, and others I've found useful. I would like to adapt these to other implementations of scheme, and/or integrate with existing projects/libraries. Help is welcome.
