CL-DOT is a Common Lisp library for generating Graphviz dot output from arbitrary Lisp data.

This is a Common Lisp library to extract EXIF information from image files.

CLAWK is an AWK implementation embedded into Common Lisp.

This library is a portable compatibility layer around "Common Lisp the Language, 2nd Edition" (https://www.cs.cmu.edu/Groups/AI/html/cltl/clm/node102.html) and it exports symbols from implementation-specific packages.

SLY is a fork of SLIME, an IDE backend for Common Lisp. It also features a completely redesigned REPL based on Emacs's own full-featured comint-mode, live code annotations, and a consistent interactive button interface. Everything can be copied to the REPL. One can create multiple inspectors with independent history.

This package defines a simple extensible protocol for computing a guess using advisors.

On Cliki.net <http://www.cliki.net/Common%20Lisp%20Utilities>, there is a collection of Common Lisp Utilities, things that everybody writes since they're not part of the official standard. There are some very useful things there; the only problems are that they aren't implemented as well as you'd like (some aren't implemented at all) and they aren't conveniently packaged and maintained. It takes quite a bit of work to carefully implement utilities for common use, commented and documented, with error checking placed everywhere some dumb user might make a mistake.

This package provides GNU gettext completely implemented in Common Lisp without any C library bindings.

This is a very short and simple program, written in Common Lisp, that extends Common Lisp to embed shell code in a manner similar to Perl's backtick. It has been forked from SHELISP.

This is a small library to display a native GUI message box. This can be useful to show error messages and other informational pieces should the application fail and be unable to do so using its standard UI.

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

This is a Common Lisp implementation of the MessagePack (http://msgpack.org/) serialization/deserialization format, implemented according to http://wiki.msgpack.org/display/MSGPACK/Format+specification.

Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

This package provides a statistical computing environment for Common Lisp.

Feeder is a syndication feed library. It presents a general protocol for representation of feed items, as well as a framework to translate these objects from and to external formats. It also implements the RSS 2.0 and Atom formats within this framework.

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

This library provides a wrapper type for secret values, to reduce the risk of accidentally revealing them.

This is a Common Lisp library providing lambda shorthand macros aiming to be used in cases where the word lambda and the arguments are longer than the body of the lambda.

This Common Lisp library provides an implementation of in-memory input streams, output streams and io streams for any type of elements.

This library is a bridge between Common Lisp and GObject Introspection, which enables Common Lisp programs to access the full interface of C+GObject libraries without the need of writing dedicated bindings.

A Common Lisp library for generating a human-readable diff of two HTML documents.

This Common Lisp package provides a regular expression engine.
