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.

MAGICFFI is a Common Lisp CFFI interface to libmagic(3), the file type determination library using magic numbers.

cl-docutils is a Common Lisp implementation of the Docutils text processing system for processing plaintext into presentational formats such as HTML and LaTeX. It is based upon the Python Docutils reference implementation but uses Common Lisp idioms making it easier to extend and more flexible. As with the reference implementation it includes a parser for the reStructured text plaintext markup syntax which is suitable for marking up documentation and for use as user markup for collaborative web sites. It is successfully used to support a higher education peer-review assessment and online tutorial system.

Caveman is intended to be a collection of common parts for web applications. Caveman2 has three design goals:

• Be extensible.

• Be practical.

• Don't force anything.

This package provides a safer variant of READ secure against internbombing, excessive input and macro characters.

The Distributions package provides a collection of probabilistic distributions and related functions

This collection of utilities is useful in contexts where you want a macro that uses lambda-lists in some fashion but need more precise processing.

This package parses and prints dates in RFC-1123 format.

This is a Common Lisp library implementing the full v1 REST API protocol for Mastodon.

It's very basic implementation of channels and queue for Common Lisp.

cl-jpl-util is a collection of Common Lisp utility functions and macros, primarily for software projects written in CL by the author.

Wu-Decimal enables convenient, arbitrary-precision decimal arithmetic through a reader macro, #$, and an update to the pprint dispatch table. Wu-Decimal uses the CL rational type to store decimals, which enables numeric functions such as +, -, etc., to operate on decimal numbers in a natural way.

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

Vom is a logging library for Common Lisp. It's goal is to be useful and small. It does not provide a lot of features as other loggers do, but has a small codebase that's easy to understand and use.

This package provides an implementation of the which UNIX command in Common Lisp.

This package provides CFFI bindings to convert between different character encodings using iconv.

Salza2 is a Common Lisp library for creating compressed data in the zlib, deflate, or gzip data formats, described in RFC 1950, RFC 1951, and RFC 1952, respectively.

Overlord is a build system in Common Lisp. It is a real build system, with all the modern features: rules with multiple outputs, parallel builds, immunity to clock issues, and dynamic dependencies.

But Overlord is more than another build system. Overlord is a uniform approach to dependencies inside or outside of a Lisp image. Overlord is to Make what Lisp macros are to C macros.

Overlord is designed to be used from the Lisp REPL. A command line interface is available in a separate repository. See https://github.com/ruricolist/overlord-cli.

This is a bindings and wrapper library to libmpg123 allowing for convenient, extensive, and fast decoding of MPEG1/2/3 (most prominently mp3) files.

cl-smug is a library for parsing text, based on monadic parser combinators. Using a simple technique from the functional programming camp, cl-smug makes it simple to create quick extensible recursive descent parsers without funky syntax or impenetrable macrology.

BORDEAUX-THREADS is a proposed standard for a minimal MP/Threading interface. It is similar to the CLIM-SYS threading and lock support.

This package provides a consolidation of Common Lisp statistics libraries.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

This package provides a Common Lisp library for defining OpenGL shader programs. There are also functions for referencing shader programs by name, querying for basic information about them, modifying uniform variables throughout the lifecycle of an OpenGL application, and managing certain OpenGL buffer object types (UBO, SSBO currently).
