Schemeish implements several useful Scheme constructs for Common Lisp. These include named-let, define, scheme argument lists, and a shortcut to FUNCALL with [] instead of ().

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

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

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.

This package provides a small utility library to open a thing (usually a file or URL) in an appropriate handler (usually an external file manager or browser).

cl-gopher is a Common Lisp library for interacting with the Gopher protocol.

It is suitable for building both clients and servers, and provides a sample client.

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.

Nyxt [nýkst] is a keyboard-driven web browser designed for hackers. Inspired by Emacs and Vim, it has familiar keybindings (Emacs, vi, CUA), and is infinitely extensible in Lisp.

cl-charms is an interface to libcurses in Common Lisp. It provides both a raw, low-level interface to libcurses via CFFI, and a more higher-level lispier interface.

This library contains an implementation of interfaces and implementations. They're sometimes called protocols in other languages. Broadly speaking, an interface is some collection of function prototypes that a valid implementation must implement.

Authentic provides a light-weight and extendible solution to user/password management for Common Lisp applications. It has features such as safe password storage in a database, password reset, user confirmation tokens, and user authentication.

cl-openal is a series of semi-lispy public domain bindings to the OpenAL API. It includes direct CFFI bindings, as well as varying levels of lispy wrappings around AL, ALC, and ALUT.

cl-webkit is a binding to WebKitGTK+ for Common Lisp, currently targeting WebKit version 2. The WebKitGTK+ library adds web browsing capabilities to an application, leveraging the full power of the WebKit browsing engine.

Parachute is a simple-to-use and extensible testing framework. In Parachute, things are organised as a bunch of named tests within a package. Each test can contain a bunch of test forms that make up its body.

This package provides highly optimized base64 encoding and decoding. Besides conversion to and from strings, integer conversions are supported. Encoding with Uniform Resource Identifiers is supported by using a modified encoding table that uses only URI-compatible characters.

Steel Bank Common Lisp (SBCL) is a high performance Common Lisp compiler. In addition to the compiler and runtime system for ANSI Common Lisp, it provides an interactive environment including a debugger, a statistical profiler, a code coverage tool, and many other extensions.

A modern markup generation library for Common Lisp that features:

• Fast (even faster through compiling the code)

• Safety

• Support for multiple document types (markup, xml, html, html5, xhtml)

• Output with doctype

• Direct output to stream

ISSR core provides functions and variables for ISSR server modules so that different servers can behave similarly. The most important features are Document Object Model differencing to generate instructions to update a DOM, and DOM cleaning, to ensure that all remote DOMs are the same.

This library implements the base58 encoding algorithm. It's basically base64 but with a smaller alphabet (58, as in the name) that doesn't include similar looking characters, among other things. See https://github.com/bitcoin/bitcoin/blob/master/src/base58.h for a full reference.

s-sysdeps is an abstraction layer over platform dependent functionality. This simple package is used as a building block in a number of other projects.

s-sysdeps abstracts:

• managing processes,

• implementing a standard TCP/IP server,

• opening a client TCP/IP socket stream,

• working with process locks.

This package lets GLOP act as a host for CEPL What?

CEPL (like GL) relies on other libraries for managing the creation of a GL context, interaction with the Window manager and handling of input sources. The libraries that provide this functionality for CEPL are called hosts.

This is a host for CEPL which uses the GLOP library for creating the context etc.

This is a very simple color library for Common Lisp, providing

• Types for representing colors in HSV and RGB spaces.

• Simple conversion functions between the above types (and also hexadecimal representation for RGB).

• Some predefined colors (currently X11 color names – of course the library does not depend on X11).Because color in your terminal is nice.

This library is no longer supported by its author.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

lparallel is a library for parallel programming in Common Lisp, featuring:

• a simple model of task submission with receiving queue,

• constructs for expressing fine-grained parallelism,

• asynchronous condition handling across thread boundaries,

• parallel versions of map, reduce, sort, remove, and many others,

• promises, futures, and delayed evaluation constructs,

• computation trees for parallelizing interconnected tasks,

• bounded and unbounded FIFO queues,

• high and low priority tasks,

• task killing by category,

• integrated timeouts.
