This library provides a tiny Common Lisp wrapper around setlocale(3) and can be used in conjunction with other FFI wrappers like cl-charms.

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

This library defines a way of treating Common Lisp packages as conduits which can sit between one or more implementation packages and users of those packages.

NJSON aims to make it convenient for one to decode, encode, and process JSON data, in the minimum keystrokes/minutes possible.

NJSON is parser-independent, with existing Common Lisp JSON parsers being loadable as additional system. jzon is included by default, though. Conveniences that NJSON provides are:

• encode and decode as single entry points for JSON reading and writing, be it from streams/string/files, or from those.

• jget, jcopy, jkeys, and their aliases to manipulate the decoded objects' properties without the need to worry about the low-level details of how these values are decoded.

• jif, jwhen, jor, jand, and other macros mimicking Lisp ones, while using truth values of JSON-decoded data.

• jbind and jmatch macros to destructure and validate parsed JSON.

• njson/aliases package to nickname to j for all the forms conveniently accessible as j:get, j:copy, j:if etc.

HARMONY is a library that provides you with audio processing tools as well as an audio server to play back music, sfx, and so forth. It is most suited for use in a game engine, but may feasibly also be used for more advanced things such as a DAW

clsql is a Common Lisp interface to SQL RDBMS based on the Xanalys CommonSQL interface for Lispworks. It provides low-level database interfaces as well as a functional and an object oriented interface.

Xmls is a self-contained, easily embedded parser that recognizes a useful subset of the XML spec. It provides a simple mapping from XML to Lisp structures or s-expressions and back.

This is a Common Lisp utilities library originating from the Zombie Raptor game engine project.

This package provides a Common Lisp Twitter client featuring full API coverage.

This is a Common Lisp library providing RFC 3986 percent-encoding.

This a Common Lisp library for reading and writing binary data. It is based on code from chapter 24 of the book Practical Common Lisp.

This package provides simple format directives to print in colors.

This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

This package provides an implementation of the hash-set data structure. It has constant time lookup, insertion and deletion.

This library is a portable compatibility layer around package local nicknames (PLN). This was done so there is a portability library for the PLN API not included in DEFPACKAGE.

This is a wrapper library to allow you to interface with the Valve SteamWorks API.

CL-FAST-ECS is a Common Lisp library providing an implementation of the ECS pattern, primarily focused on speed and interactive development.

ECS is an architectural data-oriented design pattern that allows for the effective processing of a large number of in-game objects while keeping the code and data separated. This provides flexibility in the way that game objects are built at runtime.

cl-rucksack is a persistence library based on Arthur Lemmens' Rucksack with some enhancements.

HTML parser/emitter for CommonDoc.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

Manual translation from C to Common Lisp of some random number generation functions from the GSL library.

This package provides an enhanced EVAL-WHEN macro that supports a shorthand for (eval-when (:compile-toplevel :load-toplevel :execute) ...), addressing concerns about verbosity.

cl-inotify uses cl-cffi to provide a Common Lisp interface to the Linux inotify API.

CL-PDF is a cross-platform Common Lisp library for generating PDF files.
