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

This piece of code sets up some reader macros that make it simpler to input string literals which contain backslashes and double quotes This is very useful for writing complicated docstrings and, as it turns out, writing code that contains string literals that contain code themselves.

This package provides a canonical stand-in for NIL for contexts where NIL means no value.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

This is a binding to the libyaml library. It's not meant as a full library for YAML, just a bare binding with a couple of utility macros. For a YAML parser and emitter using this, check out cl-yaml.

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 a PNG Common Lisp system to operate with Portable Network Graphics file format.

The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

Hunchenissr works together with issr.js for the development of interactive (changing without page refreshes) websites making use of websocket and Common Lisp server HTML generation instead of mountains of convoluted Javascript.

Dufy is a library for exact color manipulation and conversion in various color spaces, which supports many color models.

This is a Common Lisp autowrapping facility for quickly creating clean and lean bindings to C libraries.

fare-utils is a small collection of utilities. It contains a lot of basic everyday functions and macros.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

This package provides Common Lisp bindings to create OpenGL window and context manipulation code as well as system input handling. Direct FFI bindings to system functions are used so no third party C lib is required except system libraries.

This is a system to help you easily and quickly deploy standalone common lisp applications as binaries. Specifically it is geared towards applications with foreign library dependencies that run some kind of GUI.

CLML (Common Lisp Machine Learning) is a high performance and large scale statistical machine learning package

BOOST-RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracking VM.

This is a Common Lisp library to enable simple message pipelines.

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

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