binascii is a Common Lisp library for converting binary data to ASCII text of some kind. Such conversions are common in email protocols (for encoding attachments to support old non-8-bit clean transports) or encoding binary data in HTTP and XML applications. binascii supports the encodings described in RFC 4648: base64, base32, base16, and variants. It also supports base85, used in Adobe's PostScript and PDF document formats, and a variant called ascii85, used by git for binary diff files.

This is a Common Lisp wrapper for libjpeg-turbo library which provides TurboJPEG API for compressing and decompressing JPEG images.

Portable document preparation system.

This is a Common Lisp library providing logging faciltiy similar to CL-LOG and LOG4CL.

This library converts the elements from GObject Introspection into Common Lisp-style definitions, based on cl-gobject-introspection.

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 package provides a way of extracting and replicating the compile-time side-effects of forms.

LTK is a Common Lisp binding for the Tk graphics toolkit. It is written in pure Common Lisp and does not require any Tk knowledge for its usage.

Radiance is a web application environment, which is sort of like a web framework, but more general, more flexible. It should let you write personal websites and generally deployable applications easily and in such a way that they can be used on practically any setup without having to undergo special adaptations.

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 ().

This package provide a Common Lisp library for .zip-file reading and writing.

cl-smug is a library for parsing text, based on monadic parser combinators. Using a simple technique from the functional programming camp, cl-smug makes it simple to create quick extensible recursive descent parsers without funky syntax or impenetrable macrology.

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.

Nodgui (No Drama GUI) is a Common Lisp binding for the Tk GUI toolkit. It also provides a few additional widgets more than the standard Tk ones.

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.

Vom is a logging library for Common Lisp. It's goal is to be useful and small. It does not provide a lot of features as other loggers do, but has a small codebase that's easy to understand and use.

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.

This library provides an OS and implementation independent access to timeouts.

This Common Lisp library provides utilities for the Bodge library collection.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

The cl-sqlite package is an interface to the SQLite embedded relational database engine.

HARMONY is a library that provides you with audio processing tools as well as an audio server to play back music, sfx, and so forth. It is most suited for use in a game engine, but may feasibly also be used for more advanced things such as a DAW

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

This library contains utilities for parsing Common Lisp code.
