High performance JSON encoder and decoder. Currently support: SBCL, CCL.

This library implements a basic promise datastructure, which is useful for dealing with asynchronous behaviours. Importantly, this library does not use any other libraries or frameworks, and instead leaves the execution and state transition of promise objects in your control, making it easy to integrate.

This is a Common Lisp library providing lambda shorthand macros aiming to be used in cases where the word lambda and the arguments are longer than the body of the lambda.

Simple scheme to classify file types in a hierarchical fashion.

definitions-systems provides a simple unified extensible way of processing named definitions.

CL-ALGEBRAIC-DATA-TYPE, or ADT, is a library for defining algebraic data types in a similar spirit to Haskell or Standard ML, as well as for operating on them.

This package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

Common Lisp library for channel-based concurrency. In a nutshell, you create various threads sequentially executing tasks you need done, and use channel objects to communicate and synchronize the state of these threads.

cl-random is a library for generating random draws from various commonly used distributions, and for calculating statistical functions, such as density, distribution and quantiles for these distributions.

This is a Common Lisp implementation of the MessagePack (http://msgpack.org/) serialization/deserialization format, implemented according to http://wiki.msgpack.org/display/MSGPACK/Format+specification.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

Enchant is a Common Lisp interface for the Enchant spell-checker library. The Enchant library is a generic spell-checker library which uses other spell-checkers transparently as back-end. The library supports the multiple checkers, including Aspell and Hunspell.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

with-user-abort is a Common Lisp portability library providing a like-named macro that catches the SIGINT signal.

This is a Common Lisp bindings library to libfond, a simple OpenGL text rendering engine.

The variates package provides portable random number generation as well as numerous distributions.

40ants-plantuml provides a wrapper around the PlantUML jar library.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

Provides a simple way of directing output to a stream according to the concise and intuitive semantics of FORMAT's stream argument.

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.

Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.

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.
