This is a library for representing and mapping colours between their various spaces.

This Common Lisp library interprets escape characters the same way that most other programming language do. It provides four readtables. The default one lets you write strings like this: #"This string has a newline in it!".

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

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

This package provides a generic cache management facility with configurable and extensible cache replacement policies. The actual cached data can be stored anywhere, with cacle taking charge of keeping track of which entry is to be discarded next when more space is needed for a new entry.

This is a Common Lisp autowrapping facility for quickly creating clean and lean bindings to C libraries.

The cl-data-lens library provides a language for expressing data manipulations as the composition of more primitive operations.

CL-DEBUG provides a unified way to enable or disable debug-specific code. Debugging code can be enabled or disabled relative to program features denoted by either a symbol or a keyword.

With static-vectors, you can create vectors allocated in static memory.

This library provides a WebSocket server and client implementation for Common Lisp.

This package provides a CONSPACK implementation for Common Lisp.

CLX is an X11 client library for Common Lisp. The code was originally taken from a CMUCL distribution, was modified somewhat in order to make it compile and run under SBCL, then a selection of patches were added from other CLXes around the net.

FSet is a functional set-theoretic collections library for Common Lisp. Functional means that all update operations return a new collection rather than modifying an existing one in place. Set-theoretic means that collections may be nested arbitrarily with no additional programmer effort; for instance, sets may contain sets, maps may be keyed by sets, etc.

UBIQUITOUS is a very easy-to-use library for persistent configuration storage. It automatically takes care of finding a suitable place to save your data, and provides simple functions to access and modify the data within.

concurrent-hash-tables is a Common Lisp portability library wrapping some implementations of concurrent hash tables which do not have to be entirely locked in their operation, including 42nd-at-threadmill, luckless, and a fallback, segmented hash table.

This is a Common Lisp library to extract EXIF information from image files.

This is a baseline JPEG codec written in Common Lisp. It can be used for reading and writing JPEG image files.

Utility library for handling bit vectors, bit vector arithmetic, and universal integer type conversions between bit-vectors, byte-vectors, octals, decimals, and hexadecimal notation.

This Common Lisp library converts strings, symbols and keywords between any of the following typographical cases: PascalCase, camelCase, snake_case, kebab-case (lisp-case).

This is a backend for the linear-programming Common Lisp library using the GNU Linear Programming Kit (GLPK) library.

NClasses provides helper macros to help write classes, conditions, generic functions, and CLOS code in general with less boilerplate.

It's a fork of hu.dwim.defclass-star. It includes some bug fixes and extra features like type inference.

YASON is a Common Lisp library for encoding and decoding data in the JSON interchange format.

This package provide a Common Lisp library for .zip-file reading and writing.

This is a Common Lisp library to make histograms using UTF-8 block characters.
