TXR is a "data munging" language which combines a convenient text extraction notation that with an innovative, feature-rich Lisp dialect.
bigz is a simple but feature-rich C library for bignum calculations. It's the continuation of an old BigNum project originally begun as a research project. Current releases include many fixes, extensions and improvements. It's not as efficient as GMP, but comes with a smaller footprint, provides Z+Q infinite precision, and is rather portable and multi-thread safe.
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.
This is librep, a Lisp system for UNIX, needed by Sawfish window manager. It contains a Lisp interpreter, byte-code compiler and virtual machine. Applications may use the Lisp interpreter as an extension language, or it may be used for stand-alone scripts. The Lisp dialect was originally inspired by Emacs Lisp, but with the worst features removed. It also borrows many ideas from Scheme.
All window decorations are configurable, the basic idea is to have as much user-interface policy as possible controlled through the Lisp language. Despite this extensibility its policy is currently very minimal compared to most window managers. Its aim is simply to manage windows in the most flexible and attractive manner possible. As such it does not implement desktop backgrounds, applications docks, or other things that may be achieved through separate applications. All high-level wm functio
Kona is an implementation of the K programming language, which itself is a healthy mix of APL and LISP. The basic data constructs in K are the list, and multidimensional (up to 9 dimensions) matrix arrays. Kona itself is implemented in C and runs under Windows.
