This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

CF is a Common Lisp library for doing computations using continued fractions.

This library provides a drop-in replacement function for cl:documentation that supports multiple docstrings per-language, allowing you to write documentation that can be internationalised.

This is a repackage of the original DejaVu Fonts with some convenience functions.

This package provides an embedded template engine for Common Lisp.

CIEL is a ready-to-use collection of libraries providing: a binary, to run CIEL scripts; a simple full-featured REPL for the terminal; a Lisp library and a core image.

A common lisp library that provides extensible function result caching based on arguments (an expanded form of memoization).

This package provides a JSON Pointer (RFC6901) implementation for Common Lisp. This library aims to be independent from any JSON libraries (as much as possible).

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

A common lisp library that provides extensible function result caching based on arguments (an expanded form of memoization).

Event Emitter provides an event mechanism like Node.js for Common Lisp objects. It is mostly ported from Node.js events module.

Portability library for IEEE float features that are not covered by the Common Lisp standard.

This package provides an automatic generator for ASDF's .asd files.

This package provides a concise, intuitive and flexible macro for trivial lambdas that eschews explicit naming of parameter variables in favor of positional references, with support for a used or ignored &rest parameter and automatic declaration of ignored parameters when logical gaps are left in the positional references. Further convenience features are provided.

This library contains code that implements Common Lisp hash tables.

This a Common Lisp library for reading and writing binary data. It is based on code from chapter 24 of the book Practical Common Lisp.

This package provides an implementation of the which UNIX command in Common Lisp.

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.

This package provides a Common Lisp Twitter client featuring full API coverage.

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.

ALEXA is a tool similar to lex or flex for generating lexical analyzers. Unlike tools like lex, however, ALEXA defines a domain-specific language within your Lisp program, so you don't need to invoke a separate tool.

CL-STRFTIME is a Common Lisp compiler for the strftime “language.”

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 library can be used to print the licenses used by a Common Lisp project and its dependencies.
