Open Source Lisp Software

Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. For example, Maxima solves x^2-r*x-s^2-r*s=0, giving the symbolic results [x=r+s, x=-s]. It can also calculate with exact integers and fractions, native floating-point, and high-precision big floats. Maxima has user-friendly front-ends, an online manual, plotting commands, and numerical libraries. It features its own programming language, and many users have contributed useful packages in various areas over the decades. It is GPL-licensed and largely written in Common Lisp. Executables can be downloaded for Windows, Mac, Linux, and Android; source code is also available. An active community maintains and extends the system.

CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.

Nyquist is a language for sound synthesis and music composition. It is implemented in C and C++ and runs on Win32, OSX, and Linux. Nyquist combines a powerful functional programming style with efficient signal-processing primitives. Nyquist is also embedded as a scripting language in Audacity.

Lush is a Lisp dialect with extensions for object-oriented and array-oriented programming. Lush is intended for prototyping numerically intensive applications and is designed for easy integration of existing C/C++/Fortran codes.

ECL development has moved to https://gitlab.com/embeddable-common-lisp/ecl

BeeBase is a relational, programmable database system with graphical user interface for Windows, Mac, Linux and Amiga.

doxymacs aims to make creating/using Doxygen-created documentation easier for the {X}Emacs user.

xacc.ide is a opensource IDE aimed at mainly .NET development. It has a code editor written in 100% C# code, which is faster than most commercial offerings.

3store is an RDF "triple store", written in C and backed by MySQL and Berkeley DB. It is an optimisation and port of an older triple store (WebKBC). It provides access to the RDF data via RDQL or SPARQL over HTTP, on the command line or via a C API.

Astra is a russian ERP software for use in engeneering plants.

Sawfish is an extensible window manager using a Lisp scripting language

Ksi is a portable, embeddable Scheme implementation written in C.

AIS is an Development Platform providing a high-speed JIT compiler for LISP and JavaScript, web server, object repositories, MySQL integration and libraries supporting a wide variety of advanced genetic programming and symbolic regression techniques.

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)

It is a former "iLisp" project (N.B. - not emacs ilisp!), which is a small and embedabble Lisp-like interpreter.

Autotoolset is both a colection of small tools (scripts, emacs macros, etc.) to simplify project development with autoconf/automake/libtool/texinfo/emacs and a good documentation on how to get started on these tools and the whole GNU software model.

A Glib/GTK+/GDK language binding for the librep Lisp environment

Automatic music notation application for musicians and composers.

Matlab alternative. Scilab alternative. GNU Octave alternative. Mathematics software for numerical computation. Ordinary differential equations solver and finite elements solver. It has a console script interpreter, as well as a graphical interface script interpreter, for entering equations and statements, and a line plot display.

The PGMFI project has as its goal total understanding of the computerized systems such as ECUs, ABS controllers and other devices present in Honda vehicles. Currently, the Non-Commercial-Sharealike license is reccomended for all releases.

An OpenGL simulation of artificial life and artificial evolution using neural networks and genetic algorithms based on Larry Yaeger's PolyWorld.

Emacspeak turns Emacs into a complete audio desktop to provide a pleasurable eyes-free computing experience.

GCC-MELT is a high-level domain specific language to extend the GCC compiler. It provides several features (pattern-matching, first-class dynamically typed values, functional/applicative/object-oriented/reflective programming styles, Lisp-y syntax) MELT can also be used to explore the internal representations used by GCC (Gimple, etc...)

A Slisp interpreter to learn the basics of lisp. The main goal is to be easy to programming with it, and more easy to develop it :)

NOTE: TXR used SourceForge for hosting binary downloads only. As of July 26, 2016, TXR uses the site Bintray (bintray.com) for hosting binary downloads. Do not look for new releases here! TXR combines a text scraping language combined with an innovative Lisp dialect geared toward data munging. TXR cribs ideas from modern scripting languages, multiple Lisp dialects, functional languages, and Unix tools.
