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.​

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

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.

cl-tap-producerX is a testing framework for Common Lisp which produces reports in the TAP (Test Anything Protocol) format.

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.

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.

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.

Haskellesque lazy-list and functional tools with a Common Lisp slant.

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

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

cl-bmp is a simple library to read BMP files. The library is implemented in Common Lisp.

Swap file is a fixed block size storage library implemented in Common Lisp.

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.

Simple unit test utility for Common Lisp. Utility's unit tests are implemented with the utlity itself and unit tests cover 100% of the code.

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.

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.

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.

The CLAST library provides parsing, AST manipulation and "walking" for Common Lisp code.

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.
