Optima is a fast pattern matching library which uses optimizing techniques widely used in the functional programming world.

This library implements special functions and has a focus on high accuracy double-float calculations using the latest algorithms.

CAMBL is a Common Lisp library providing a convenient facility for working with commoditized values. It does not allow compound units (and so is not suited for scientific operations) but does work rather nicely for the purpose of financial calculations.

This is a Common Lisp library providing RFC 3986 percent-encoding.

Enables fast and convenient interoperation with foreign objects.

Portable document preparation system.

CLACHE provides a general caching facility for Common Lisp. The API is similar to the standard hash-table interface.

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 package is a Python Numpy clone implemented in pure Common Lisp.

This package provides a Common Lisp bindings to glfw, an OpenGL application development library.

This is a Common Lisp implementation of the Encoding for Robust Immutable Storage specification (ERIS).

This project is intended as a catchall for small, general-purpose extensions to Common Lisp. It contains:

• new-let, a macro that combines and generalizes let, let* and multiple-value-bind,

• gmap, an iteration macro that generalizes map.

A CLOS class that defines callable objects whose behavior is similar to closures but adds conveniences such as introspectability.

S-XML-RPC is an implementation of XML-RPC in Common Lisp for both client and server.

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

This is a Common Lisp library providing functions to read/write CSV from/to strings, streams and files.

cl-random is a library for generating random draws from various commonly used distributions, and for calculating statistical functions, such as density, distribution and quantiles for these distributions.

This library defines most Common Lisp standard macros that can be defined in a portable way and that can generate portable code. Some of these macros may not be good enough as the final version for a typical implementation, but they will work.

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

cl-incless implements print-object methods for many standard classes.

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

This package provides a canonical way of converting class designators to classes.

This is a Common Lisp library for reading and printing MIME content. It supports automatic conversion between 7-bit, quoted-printable and base64 encodings.

trivial-download allows you to download files from the Internet from Common Lisp. It provides a progress bar.
