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.

40ants-asdf-system provides a class for being used instead of asdf:package-inferred-system in 40ANT systems.

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 package provides easy access to the defining class and its options during initialization or reinitialization of its subcomponents.

This is a reverse proxy server written in and configurable in Common Lisp. It supports WebSocket, HTTP, HTTPS, HTTP to HTTPS redirecting, port and host forwarding configuration using a real programming language, HTTP header and body manipulation (also using a real programming language).

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

This library features a rectangle packer for sprite and texture atlases.

Clamp is an attempt to bring the powerful, but verbose, language of Common Lisp up to the terseness of Arc.

There are two parts to Clamp. There is the core of Clamp, which implements the utilities of Arc that are easily converted from Arc to Common Lisp. The other part is the "experimental" part. It contains features of Arc that are not so easy to copy (ssyntax, argument destructuring, etc.).

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

bt-semaphore is a semaphore implementation for use with bordeaux-threads.

This is a small OS portability library to retrieve and set file attributes not supported by the Common Lisp standard functions.

This library provides almost the same code as used inside Quicklisp for drawning progress bars

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

Trivial Monitored Thread offers a very simple (aka trivial) way of spawning threads and being informed when one any of them crash and die.

This package provides functions to emit XML, with some complexity for handling indentation. It can be used to produce all sorts of useful XML output; it has an RSS 2.0 emitter built in, so you can make RSS feeds trivially.

This package provides a Common Lisp implementation of the semantic versioning specification: http://semver.org.

This is a library for quaternions. It contains most of the quaternion operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable. It also tries to be efficient where plausible. Each quaternion is made up of floats, which by default are single-floats, as they do not require value boxing on most modern systems and compilers.

This Common Lisp package contains the core math utilities of the Bodge library collection.

This package exports the following function to parse floating-point values from a string in Common Lisp.

This package provides a Common Lisp system implementing event bus.

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.

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.

From a string input and a list of candidates, return the most relevant candidates first.

cl-strings is a small, portable, dependency-free set of utilities that make it even easier to manipulate text in Common Lisp. It has 100% test coverage and works at least on sbcl, ecl, ccl, abcl and clisp.
