Open Source Common Lisp Software for BSD

Lisp Koans is a self-guided learning path for Common Lisp that teaches the language’s idioms through a series of failing tests you progressively make pass. Each koan introduces a concept—symbols, lists, macros, multiple dispatch, reader syntax—then asks you to fill in the blanks and run the suite again. The feedback loop is intentionally tight: fail, reflect, fix, and rerun until the tests become a form of living documentation. Because koans are organized from fundamentals to metaprogramming, learners internalize not just syntax but also Lisp’s philosophy of code-as-data. The exercise format makes it ideal for workshops, katas, or leveling up engineers who have never touched a Lisp before. It’s minimal on infrastructure and maximal on discovery, encouraging use of a REPL and inspector while you solve each puzzle.

STEP (ISO 10303) development environment which supports the validation of STEP data populations via EXPRESS (ISO 10303-11) schemata and the transformation of STEP data populations from one schema to another via EXPRESS-X (ISO 10303-14) schemata.

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.

Garnet is a Graphical Toolkit for Lisp, which offers many advanced features. It was originally developed by Carnegie Mellon's User Interface Software Group and is one of the most feature rich interface toolkits available for lisp. The project has been dormant but some of us are trying to update it. To get the latest stable code, use the subversion repository: svn checkout svn://svn.code.sf.net/p/garnetlisp/svn/trunk garnetlisp-svn

OpenAxiom is an open source Computer Algebra System. It offers an interactive environment, an expressive programming language, a compiler, a large set of mathematical libraries of interest to researchers and practitioners of computational sciences.

The Common Lisp Reasoner extends the Common Lisp Object System (CLOS) to incorporate a powerful rule language suitable for all kinds of reasoning tasks, vanilla XML and RDF/XML interfaces, and support for a variety of AI-related applications, such as scheduling, planning and diagnosis.

GTK2 binding for common lisp, based on CFFI and CLOS

COOK is a software build-automation tool made with a goal of letting you, the programmer, to utilize the most elegant and powerful programming language - Common Lisp - for managing your software builds. You write a recipe file which describes what objectives must be constructed. COOK will load and process this file, then produce either a regular Makefile or a Bourne Shell script, which will actually perform the task of building and installing your targets.

SNMP (Simple Network Management Protocol) for Common Lisp, UDP Networking for LispWorks, ...

Deep Space Window Manager is a tiling window manager, oriented for good usability with minimum startup configuration and good integration with EMACS. DSWM based on StumpWM code. Now project is under hard development so has many experimental features.

Tools for SSA->SRT conversion and editing of SRT subtitles: * ssa2srt - converts SSA/ASS subtitles to SubRip format; * fixsrtsub - fixes SubRip subtitles.

Snow is a Lisp-based GUI description DSL for Swing. It supports declarative layout, data binding, event listeners implemented in Java or Lisp. NOTE: the project is now hosted on common-lisp.net.

Unlike conventional audio players, ARITA aims to help music lovers to keep their precious collections well organized and tidy. Therefore it takes a different approach to arranging audio files. They must be emplaced into libraries: 'archives' or 'cuesheets'. Archive - compressionless container like CPIO. Instead of tags for description of tracks, a plain XML/YAML file is placed alongside each archive. Rather than embedding cover art in every track, put a single image next to a library. TIFF supports multipage docs, so scans of covers/discs can be packed together in one file. ARITA will locate and display the said file, allowing you to view all pages. Optional 'signature' files can be created to keep checksums of tracks, so you may ask ARITA to verify them and make sure nothing is damaged due to a sudden failure of HDD/SSD. As for 'cuesheets': tracks are merged into a single continuous audio file and a supplementary text file, which provides information on where tracks start and end.

Acheron is a Common Lisp (CL) to JavaScript (JS) compiler. Programs are written in a subset of CL and after compilation executed in a webbrowser. Acheron has native functions that are written in JS and are the bridge between CL and JS.

Compiler of Lisp programs to a platform-idependent bytecode and the corresponding virtual machine.

A general and small implementation of an artificial neural network in Common Lisp.

Hard disk forensics in the lisp way.

cl-pcp is a collection of Common Lisp CFFI bindings for Pango, Cairo, and PixBuf from the GTK+ (Gimp Tool Kit) Project. This is meant as a lightweight, general solution for developing graphical/text based applications in Common Lisp.

CIOS Audio Core is the infrastructure and subsystem in Collective Intelligence Operation System. It is a cross platforms audio abstract interface, supports including Mac OS X, Linux, Android, iPhone OS and Windows 7.

CLearJ is a clean Java-implementation of Common Lisp. The big goals are ANSI standard compliance, interoperability with Java and integration with scripting environments. This project is meant to be a sibling to CLearSharp, with sharing of implementation.

CLearSharp is a clean C#-implementation of Common Lisp. The big goals are ANSI standard compliance, interoperability with Java and integration with scripting environments. This project is meant to be a sibling to CLearJ, with sharing of implementation.

A Cobol compiler, implemented as a new front end to the GCC compiler.
