This is futures implementation for Common Lisp. It plugs in nicely to cl-async.

Command-Line-Args provides a main macro (command) that wraps a defun form and creates a new function that parses the command line arguments. It has support for command-line options, positional, and variadic arguments. It also generates a basic help message. The interface is meant to be easy and non-intrusive.

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

Authentic provides a light-weight and extendible solution to user/password management for Common Lisp applications. It has features such as safe password storage in a database, password reset, user confirmation tokens, and user authentication.

Wu-Decimal enables convenient, arbitrary-precision decimal arithmetic through a reader macro, #$, and an update to the pprint dispatch table. Wu-Decimal uses the CL rational type to store decimals, which enables numeric functions such as +, -, etc., to operate on decimal numbers in a natural way.

CL-DEBUG provides a unified way to enable or disable debug-specific code. Debugging code can be enabled or disabled relative to program features denoted by either a symbol or a keyword.

Simple library to create temporary directories.

YASON is a Common Lisp library for encoding and decoding data in the JSON interchange format.

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

A client for the Stripe payment API.

This Common Lisp library focuses on the small set of basic color manipulations (lightening, compliments, etc.) you might use to generate a color palette for a GUI or web page.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

This library allows creation of hash tables with arbitrary test/hash functions, in addition to the test functions allowed by the standard (EQ, EQL, EQUAL and EQUALP), even in implementations that don't support this functionality directly.

GECO (Genetic Evolution through Combination of Objects) is an extensible, object-oriented framework for prototyping genetic algorithms in Common Lisp.

cl-cffi-gtk is a Lisp binding to GTK+ 3 (GIMP Toolkit) which is a library for creating graphical user interfaces.

This is a system for two dimensional computational geometry for Common Lisp.

Note: the system assumes exact rational arithmetic, so no floating point coordinates are allowed. This is not checked when creating geometric objects.

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

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.

This library strives to provide a portable TCP/IP and UDP/IP socket interface for as many Common Lisp implementations as possible, while keeping the abstraction and portability layer as thin as possible.

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

System-Load is a Common Lisp library for accessing the system's CPU and memory usage.

Domain specific language for producing TeX documents with Common Lisp.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.
