simple-optimization is a Common Lisp library providing a function to solve unconstrained optimization problems numerically using either the gradient descent or a quasi-Newton method.

This package provides a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

PARSER-COMBINATORS is a library implementing monadic parser combinators in Common Lisp, similar in concept to Haskell Parsec system.

This is a Common Lisp library to calculate std140 or std430 layouts for a glsl UBO/SSBO.

HTTP-Body parses HTTP POST data and returns POST parameters. It supports application/x-www-form-urlencoded, application/json, and multipart/form-data.

This library defines a way of treating Common Lisp packages as conduits which can sit between one or more implementation packages and users of those packages.

On Cliki.net <http://www.cliki.net/Common%20Lisp%20Utilities>, there is a collection of Common Lisp Utilities, things that everybody writes since they're not part of the official standard. There are some very useful things there; the only problems are that they aren't implemented as well as you'd like (some aren't implemented at all) and they aren't conveniently packaged and maintained. It takes quite a bit of work to carefully implement utilities for common use, commented and documented, with error checking placed everywhere some dumb user might make a mistake.

Use rich-formatter to format documentation with sections :syntax, :arguments, :examples, :description, :returns, :side-effects, :thread-safety, :affected-by, :see-also and :notes. Gather unformatted input by using rich-aggregating-formatter and *DOCUMENTATION* variable. Find gathered documentation with find-documentation function. Execute code stored in documentation with execute-documentation. See the examples in the src/documentation.lisp file. See the documentation-utils system for more information.

Birch is a simple Common Lisp IRC client library. It makes use of CLOS for event handling.

This is a Common Lisp logging framework that can log at various levels and mix text with expressions.

Simple color library for Common Lisp.

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

This package provides a flexible shallow/deep copy mechanism for Common Lisp.

CLX-TrueType is pure common lisp solution for antialiased TrueType font rendering using CLX and XRender extension.

This package provides CFFI bindings to the Graphviz library in Common Lisp.

Eager Future2 is a Common Lisp library that provides composable concurrency primitives that unify parallel and lazy evaluation, are integrated with the Common Lisp condition system, and have automatic resource management.

This is a Common Lisp library which provides functionality to read/write Bit Map Font (BMF) into text, JSON and XML.

cl-tar-file is a Common Lisp library that allows reading from and writing to various tar archive formats. Currently supported are the POSIX ustar, PAX (ustar with a few new entry types), GNU, and v7 (very old) formats.

This library is rather low level and is focused exclusively on reading and writing physical tar file entries using streams. Therefore, it contains no functionality for automatically building archives from a set of files on the filesystem or writing the contents of a file to the filesystem. Additionally, there are no smarts that read multiple physical entries and combine them into a single logical entry (e.g., with PAX extended headers or GNU long link/path name support). For a higher-level library that reads and writes logical entries, and also includes filesystem integration, see cl-tar.

A Common Lisp library for computing differences between sequences based on the Python difflib module.

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.

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

FXML is a secure-by-default, error-recovering XML parser and serializer. It is a fork of CXML.

You should use FXML instead of CXML if:

• You are parsing potentially ill-formed XML.

• You are parsing potentially malicious XML.

• You need to use Klacks with namespaces.

FXML’s API is very close to CXML's, and for the most part you can refer to the CXML documentation for usage.

Metatilities-base is the core of the metatilities Common Lisp library which implements a set of utilities.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and Maidenhead locator system.
