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.

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.

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 Though no longer actively maintained, Schism remains a valuable example of how high-level languages can be mapped to WebAssembly and offers insights into language implementation.

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).

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.

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.

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

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.

Genjutsu is a programming language designed for extending C/C++ applications. The syntax is akin to Scheme's. Genjutsu is optimized for distributed object systems and designed to make such applications easy to write. Included is a shell, gjsh.

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.

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.

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

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 web server written in gambit/scheme that implements push technology and abstracts it trought actor model, implements too a compiler of yera, a language to describe gui in terms of functional reactive programming.

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

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.

upload/donwload/fun

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

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.

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.
