3D-VECTORS is a library for vector math in 3D space. It contains most of the vector operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable.

(X)HTMLambda is yet another (X)HTML library which emphasizes programmability and user-friendliness. Each (X)HTML element is a structured object and pretty-printing of (X)HTML trees is well defined to provide properly indented human-readable output even for complex recursive arrangements.

Wu-Decimal enables convenient, arbitrary-precision decimal arithmetic through a reader macro, #$, and an update to the pprint dispatch table. Wu-Decimal uses the CL rational type to store decimals, which enables numeric functions such as +, -, etc., to operate on decimal numbers in a natural way.

This is a very simple color library for Common Lisp, providing:

• Types for representing colors in HSV, HSL, and RGB spaces.

• Simple conversion functions between the above types.

• Function printing colors to HEX, RGB, RGBA, and HSL.

• Predefined colors from X11, SVG, and GDK.

This package provides functions for generating lorem ipsum text.

A library for encoding text in various web-savvy encodings.

The Lisp Critic scans your code for instances of bad Lisp programming practice.

Library to fuzzily parse time and date strings into a universal-time timestamp.

This package provides a way of extracting and replicating the compile-time side-effects of forms.

This package exports the following function to parse floating-point values from a string in Common Lisp.

A miniature toolkit that contains some useful shifting/popping/pushing functions for arrays and vectors. Originally from Plump.

string-case is a Common Lisp macro that generates specialised decision trees to dispatch on string equality.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

This is a Common Lisp macro for defining temporary caches that invalidate based on expressions evaluating to different values.

Often times we need to destructure a form definition in a Common Lisp macro. This library provides a set of simple utilities to help with that.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

Loop has a consistent interface unlike other looping abstractions and ANSI list operations. You can define your own efters and gatherers that integrate tightly into other operations. All operations are non-consing when possible.

This is only useful if you want to start a Swank server in a Lisp processes that doesn't run under Emacs. Lisp processes created by M-x slime automatically start the server.

This package provides functions to emit XML, with some complexity for handling indentation. It can be used to produce all sorts of useful XML output; it has an RSS 2.0 emitter built in, so you can make RSS feeds trivially.

This system implements a general definitions introspection library. It gives you the ability to retrieve definitions or bindings associated with designators such as symbols, packages, and names in general. For instance, it allows you to retrieve all function, type, variable, method, etc. definitions of a symbol.

In Common Lisp, a special variable that is never dynamically bound typically serves as a stand-in for a global variable. The global-vars library provides true global variables that are implemented by some compilers. An attempt to rebind a global variable properly results in a compiler error. That is, a global variable cannot be dynamically bound.

Global variables therefore allow us to communicate an intended usage that differs from special variables. Global variables are also more efficient than special variables, especially in the presence of threads.

This is a Common Lisp library providing various utilities.

This package defines a simple extensible protocol for computing a guess using advisors.

Various ASDF extensions such as attached test and documentation system, explicit development support, etc.
