Implementation of a set-like data structure with constant time addition, removal, and random selection.

MOP utilities provide a common interface between Lisps and make the MOP easier to use.

Porter Stemming Algorithm.

This package provides CFFI binding to libmixed audio library for Common Lisp with support of other audio formats available on GNU/Linux systems:

• Alsa

• Jack

• Openmpt

• PulseAudio

• Flac (via CL-FLAC)

• Mpg123 (via CL-MPG123)

• Ogg/vorbis (via CL-VORBIS)

• Out123 (via CL-OUT123)

• WAV

This library provides all of

• ad hoc polymorphism and

• subtype polymorphism

• parametric polymorphism (in a very limited sense)

to dispatch on the basis of types rather than classes.

HTML parser/emitter for CommonDoc.

This Common Lisp library provides optimized byte-swapping primitives. The library can change endianness of unsigned integers of length 1/2/4/8. Very useful in implementing various network protocols and file formats.

This is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

This project is intended as a catchall for small, general-purpose extensions to Common Lisp. It contains:

• new-let, a macro that combines and generalizes let, let* and multiple-value-bind,

• gmap, an iteration macro that generalizes map.

Filtered functions provide an extension of CLOS generic function invocation that add a simple preprocessing step before the actual method dispatch is performed and thus enable the use of arbitrary predicates for selecting and applying methods. See http://www.p-cos.net/documents/filtered-dispatch.pdf for a paper that introduces and explains filtered functions in detail.

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

NFiles is a Common Lisp library to help manage file persistence and loading, in particular user-centric files like configuration files. It boasts the following features:

• Dynamic and customizable path expansion.

• Extensible serialization and deserialization.

• Cached reads and writes. When a file object expands to the same path as another one, a read or write on it won’t do anything in case there was no change since last write.

• (Experimental!) On-the-fly PGP encryption.

• Profile support.

• On read error, existing files are backed up.

• On write error, no file is written to disk, the existing file is preserved.

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.

This library can be used to print the licenses used by a Common Lisp project and its dependencies.

This Common Lisp library implements the quoted-printable encoding as described in RFC 2045 (see http://tools.ietf.org/html/rfc2045).

This is a library to provide cross-platform access to gamepads, joysticks, and other such HID devices.

A small collection of common lisp macros to make collecting values easier.

Conium is a portability library for debugger- and compiler-related tasks in Common Lisp. It is fork of SWANK-BACKEND.

Anaphora is the anaphoric macro collection from Hell: it includes many new fiends in addition to old friends like aif and awhen.

This is a collection of common cryptography functions for Common Lisp.

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

simple-routes is a simple Common Lisp RESTful routing facility on top of Hunchentoot.

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