definitions-systems provides a simple unified extensible way of processing named definitions.

The Common Lisp Application Directories (CLAD) library is a simple API collection that provides access to a set of standard Common Lisp folders on a per-application or per-library basis.

An implementation of Relax NG schema validation written in Common Lisp, including support for compact syntax, DTD Compatibility, and the XSD type library.

This package is a geospatial library, based on cl-wkb, that implements the OGC Well-Known Binary geographic geometry data model with PostGIS 3d, 4d extensions, and provides WKB and EWKB encoding and decoding functionality.

bubble-operator-upwards is a function that bubbles an operator upwards in a form, demultiplexing all alternative branches by way of cartesian product.

CL-DISKSPACE is a Common Lisp library to list disks with the command line tool df and get disk space information using statvfs.

cl-quicklisp-stats is a system that fetches and performs basic operations on the Quicklisp download statistics.

Trial is a game engine written in Common Lisp. Unlike many other engines, it is meant to be more of a loose connection of components that can be fit together as required by any particular game.

cl-cron is a simple tool that provides cron like facilities directly inside of Common Lisp.

Trial is a game engine written in Common Lisp. Unlike many other engines, it is meant to be more of a loose connection of components that can be fit together as required by any particular game.

The Babel library solves a similar problem while understanding more encodings. Trivial UTF-8 was written before Babel existed, but for new projects you might be better off going with Babel. The one plus that Trivial UTF-8 has is that it doesn't depend on any other libraries.

Triads is a simple command line tool that reads roman numeral notation from standard input (or a file) and an musical key and outputs the roman numeral in addition to the notes of the triad associated with that roman numeral given in the key.

This is a portability library that allows one to fully override the standard debugger provided by their Common Lisp system for situations where binding *debugger-hook* is not enough -- most notably, for break.

Germinal is a server for the Gemini protocol, written in Common Lisp.

A collection of Common Lisp utility functions and macros mostly not found in other utility packages.

This is a Common Lisp library to handle the IBM PC version of the IXF (Integration Exchange Format) file format.

Alexandria is a collection of portable utilities. It does not contain conceptual extensions to Common Lisp. It is conservative in scope, and portable between implementations.

Duologue is high-level interaction library for Common Lisp. It features coloured printing via cl-ansi-text and readline completion.

This package creates GraphViz DOT files from an equivalent s-expression representation.

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

This package provides a pure-lisp implementation of a DNS client. It can be used to resolve hostnames, reverse-lookup IP addresses, and fetch other kinds of DNS records.

concurrent-hash-tables is a Common Lisp portability library wrapping some implementations of concurrent hash tables which do not have to be entirely locked in their operation, including 42nd-at-threadmill, luckless, and a fallback, segmented hash table.
