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

This package provides the Common Lisp HTTP server WOO, which is built on top of the libev event library.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

This is a Common Lisp wrapper for interacting with the Redis data structure store.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

cl-mysql is a Common Lisp implementation of a MySQL wrapper.

This is a teensy library that provides some functions to determine the mime-type of a file.

The Type-Templates library allows you to define types and “template functions” that can be expanded into various type-specialized versions to eliminate runtime dispatch overhead. It was specifically designed to implement low-level numerical data types and functionality.

Typo is a portable library for Common Lisp that does approximate reasoning about types, but without consing.

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.).

CL-DATA-STRUCTURES is a Common Lisp library providing a portable collection of mutable and immutable data structures (dictionaries, sets, queues, sequences) and algorithms.

This package provides a concise, intuitive and flexible macro for trivial lambdas that eschews explicit naming of parameter variables in favor of positional references, with support for a used or ignored &rest parameter and automatic declaration of ignored parameters when logical gaps are left in the positional references. Further convenience features are provided.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

This is a library for selecting portions of sequences, arrays or data-frames.

This package provides Common Lisp bindings to access the linear algebra libraries using the CBLAS API. Currently the OpenBLAS implementation is used.

This project is meant to provide tools for internationalizing Common Lisp programs.

One important aspect of internationalization is of course the language used in error messages, documentation strings, etc. But with this project we provide tools for all other aspects of internationalization as well, including dates, weight, temperature, names of physical quantities, etc.

System-Load is a Common Lisp library for accessing the system's CPU and memory usage.

Arrow-macros provides clojure-like arrow macros (ex. ->, ->>) and diamond wands in swiss-arrows.

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.

This is a small library providing the ISO-639 language code to language name mapping.

This package provides a macro commonly used in livecoding to enable continuing when errors are raised. Simply wrap around a chunk of code and it provides a restart called continue which ignores the error and carrys on from the end of the body.

Support library for numcl. Registers a function as an additional form that is considered as a candidate for a constant.

This package provides CFFI bindings for Common Lisp to the Cairo C library.
