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 can be used to display a progress bar on one line.

A simple Common-Lisp interface to the underlying operating system. It's independent of the implementation and operating system.

This library is a universal interface to the operating system package manager. It has extensive support for Guix, among others:

• package listing and searching;

• package installation and uninstallation;

• package file listing;

• profile listing;

• manifest listing and installation;

• generation listing, switching and deletion.

Caveman is intended to be a collection of common parts for web applications. Caveman2 has three design goals:

• Be extensible.

• Be practical.

• Don't force anything.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

CLML (Common Lisp Machine Learning) is a high performance and large scale statistical machine learning package

This is a small library to display a native GUI message box. This can be useful to show error messages and other informational pieces should the application fail and be unable to do so using its standard UI.

This is a portable Universal Resource Identifier library for Common Lisp programs. It parses URI according to the RFC 2396 specification.

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

Fast-io is about improving performance to octet-vectors and octet streams (though primarily the former, while wrapping the latter).

Simple color library for Common Lisp.

This system implements binding threading macros -- a kind of threading macros with different semantics than classical, Clojure core threading macros or their extension, swiss-arrows. Two Common Lisp implementations of those are arrows and arrow-macros.

This system is a fork of arrows with changes in semantics that make it impossible to merge back upstream.

This library is part of NUMCL. It provides a macro SPECIALIZED that performs a Julia-like dispatch on the arguments, lazily compiling a type-specific version of the function from the same code. The main target of this macro is speed.

McCLIM is an implementation of the Common Lisp Interface Manager specification, a toolkit for writing GUIs in Common Lisp.

Ningle is a lightweight web application framework for Common Lisp.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

From a string input and a list of candidates, return the most relevant candidates first.

NDebug provides a small set of utilities to make graphical (or, rather non-REPL-resident) Common Lisp applications easier to integrate with the standard Lisp debugger (*debugger-hook*, namely) and implementation-specific debugger hooks (via trivial-custom-debugger), especially in a multi-threaded context.

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

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.

Gray streams is an interface proposed for inclusion with ANSI CL by David N. Gray. The proposal did not make it into ANSI CL, but most popular CL implementations implement it. This package provides an extremely thin compatibility layer for gray streams.

A simple Common-Lisp interface to the underlying operating system. It's independent of the implementation and operating system.

Anaphora is the anaphoric macro collection from Hell: it includes many new fiends in addition to old friends like aif and awhen.
