Clavier is a general purpose validation library for Common Lisp.

Implementation of a set-like data structure with constant time addition, removal, and random selection.

fast-websocket is an optimized low-level WebSocket protocol parser/composer.

Optima is a fast pattern matching library which uses optimizing techniques widely used in the functional programming world.

This package provides a SuperCollider client for Common Lisp.

Helps writing concise CFFI-related code.

DEFPACKAGE-PLUS is an extensible DEFPACKAGE variant with predictable cross-platform behavior and some utilities useful for versioning.

This is a binding to the libyaml library. It's not meant as a full library for YAML, just a bare binding with a couple of utility macros. For a YAML parser and emitter using this, check out cl-yaml.

This library introduces fast generic functions, i.e. functions that behave just like regular generic functions, except that the can be sealed on certain domains. If the compiler can then statically detect that the arguments to a fast generic function fall within such a domain, it will perform a variety of optimizations.

Implementation of a set-like data structure with constant time addition, removal, and random selection.

This package provides a recursive-descent parser DSL for Common Lisp. It's intended as a simpler alternative to parser generators.

This package provides a UTF-8 string input stream over a binary stream for Common Lisp.

colorize is a Lisp library for syntax highlighting supporting the following languages: Common Lisp, Emacs Lisp, Scheme, Clojure, C, C++, Java, Python, Erlang, Haskell, Objective-C, Diff, Webkit.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

Parse-js is a Common Lisp package for parsing JavaScript (ECMAScript 3). It has basic support for ECMAScript 5.

Metatilities-base is the core of the metatilities Common Lisp library which implements a set of utilities.

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

This library is a universal interface to the operating system package manager. It has extensive support for Guix, among others:

• package listing and searching;

• package installation and uninstallation;

• package file listing;

• profile listing;

• manifest listing and installation;

• generation listing, switching and deletion.

string-pokemonize provides a function that alternates uppercase and lowercase characters for a given string.

This is a purely math-related utility kit, providing functions which can be useful for games, 3D, and GL in general.

This package provides a simple yet powerful value inheritance scheme.

This library implements the base58 encoding algorithm. It's basically base64 but with a smaller alphabet (58, as in the name) that doesn't include similar looking characters, among other things. See https://github.com/bitcoin/bitcoin/blob/master/src/base58.h for a full reference.

This is a Common Lisp library providing various utilities.

EXTERNAL-PROGRAM enables running programs outside the Lisp process. It is an attempt to make the RUN-PROGRAM functionality in implementations like SBCL and CCL as portable as possible without sacrificing much in the way of power.
