TXR is a "data munging" language which combines a convenient text extraction notation that is equivalent in power to Parse Expression Grammars, with an innovative Lisp dialect which manages to integrate the differences between Lisp-1 and Lisp-2, has built-in lazy lists, strings and vectors that can be treated with list processing functions, currying operators, macros with destructuring lambda lists, macrolet, symbol macros, dynamically scoped variables, exception handling, and object-oriented st
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.
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
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.
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.
