RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracing VM.

Enables fast and convenient interoperation with foreign objects.

Simple scheme to classify file types in a hierarchical fashion.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

This package provides some condition classes, functions and macros which may be useful when building slightly complex systems.

A Common Lisp library for generating a human-readable diff of two HTML documents.

Lack is a Common Lisp library which allows web applications to be constructed of modular components. It was originally a part of Clack, however it's going to be rewritten as an individual project since Clack v2 with performance and simplicity in mind.

This library is part of NUMCL. It provides a macro SPECIALIZED that performs a Julia-like dispatch on the arguments, lazily compiling a type-specific version of the function from the same code. The main target of this macro is speed.

deeds allows for efficient event delivery to multiple handlers with a complex event filtering system.

This Common Lisp library provides an implementation of in-memory input streams, output streams and io streams for any type of elements.

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.

Clavier is a general purpose validation library for Common Lisp.

This package provides a flexible shallow/deep copy mechanism for Common Lisp.

This package provides a Common Lisp system which wraps the BORDEAUX-THREADS system to be able to run things in the main thread of the implementation, for example drawing calls of GUI applications.

Forge is a generic build system. Refer to documentation for the specific kind of project you're building to get the full picture.

wild-package-inferred-system is an extension of ASDF package-inferred-system that interprets star * and globstar ** in package or system names.

This package provides a pure-lisp implementation of a DNS client. It can be used to resolve hostnames, reverse-lookup IP addresses, and fetch other kinds of DNS records.

Enables fast and convenient interoperation with foreign objects.

Napa-FFT3 provides Discrete Fourier Transform (DFT) routines, but also buildings blocks to express common operations that involve DFTs: filtering, convolutions, etc.

This is a Common Lisp wrapper for libjpeg-turbo library which provides TurboJPEG API for compressing and decompressing JPEG images.

lQuery is a DOM manipulation library written in Common Lisp, inspired by and based on the jQuery syntax and functions. It uses Plump and CLSS as DOM and selector engines. The main idea behind lQuery is to provide a simple interface for crawling and modifying HTML sites, as well as to allow for an alternative approach to templating.

This is a lisp implementation of the Open Sound Control protocol (or more accurately “data transport specification” or “encoding”). The code should be close to ANSI standard common lisp and provides self contained code for encoding and decoding of OSC data, messages, and bundles.

This is a Common Lisp wrapper for libjpeg-turbo library which provides TurboJPEG API for compressing and decompressing JPEG images.

This library is a Common Lisp port of all the constants from the event codes header file found on Linux and FreeBSD.
