Open Source Common Lisp Software Development Software

Steel Bank Common Lisp (SBCL) is a high-performance Common Lisp compiler. It is open-source/free software, with a permissive license. In addition to the compiler and runtime system for ANSI Common Lisp, it provides an interactive environment including a debugger, a statistical profiler, a code coverage tool, and many other extensions. SBCL runs on Linux, various BSDs, macOS, Solaris, and Windows. See the download page for supported platforms, and the getting started guide for additional help. SBCL is available in source and binary form for a number of different architectures. SBCL is available in binary form for many architectures. To obtain the latest binary release for your system, visit the platform support page and click on the green square which indicates your platform. You can install SBCL to a different directory prefix by setting the INSTALL_ROOT environment variable before running the installation script.

Qlot is a project-local library installer for Common Lisp, utilizing the Quicklisp facility. It enables developers to manage dependencies on a per-project basis, ensuring consistent environments and avoiding conflicts between projects. Qlot is akin to Bundler for Ruby or Carton for Perl, providing a familiar experience for developers from other ecosystems.​

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

B-Tree implemented in Common Lisp. Stores key/value pairs onto disk based data structure. Current implementation has been tested with SBCL. Project was originally at alien-consader.org but is now made available at SourceForge.

Toolbox contains a few common utilities used in other projects. Toolbox has also for example a generic non-trivial double-linked list implementation which uses SBCL's weak-pointers when referencing to previous item.

Soulski, an open source Soulseek client for Windows written in Common Lisp.

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 Chinese translation of Paul Graham's famous book: On Lisp.

STMX is a high-performance Common Lisp library for composable Transactional Memory (TM), a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions: if a memory transaction returns normally it gets committed, if instead it signals an error (Lisp slang for throwing an exception) it is rolled back. Memory transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and effects of a transaction are not visible from other threads until it commits. STMX gives freedom from deadlocks, automatic rollback on failure, and it aims at resolving the tension between granularity and concurrency.

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.

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

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.

ABCL-web is a web-framework using Armed Bear Common Lisp as a Java Servlet

Binary file format provides interface for Common Lisp to read and write binary files in a simple way.

cl-wal is a simple write ahead log library implemented in Common Lisp. Write ahead log writes entries first to a journal and then to master stream.

gennf is a distributed version management system with code signing support written in Common Lisp incorporating ideas from Meta-CVS.

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

Axiom is a computer algebra system. It consists of an interpreter, a compiler and a library of algorithms. Axiom is an excellent research platform as well as a useful tool for scientific programming.

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.

Web development framework for Common Lisp, based on FastCGI with integrated WiKi. It is tested mainly on SBCL, but should work on most Common Lisp implementations.

Small implementation of Push 3 programming language in Common Lisp. Push 3 is described here http://tinyurl.com/push30. Push is a programming language intended primarily for use in evolutionary computation systems.
