This package ensures that special subclasses of standard-object cluster right in front of standard-object in the class precedence list.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and Open Location Code.

This package provides a UTF-8 string input stream over a binary stream for Common Lisp.

Common Lisp ships with a set of powerful built in data structures including the venerable list, full featured arrays, and hash-tables. CL-containers enhances and builds on these structures by adding containers that are not available in native Lisp (for example: binary search trees, red-black trees, sparse arrays and so on), and by providing a standard interface so that they are simpler to use and so that changing design decisions becomes significantly easier.

A modern markup generation library for Common Lisp that features:

• Fast (even faster through compiling the code)

• Safety

• Support for multiple document types (markup, xml, html, html5, xhtml)

• Output with doctype

• Direct output to stream

PP-TOML is a Common Lisp library for parsing strings in the TOML configuration file format. It implements only the 0.1.0 specification of TOML.

Antik provides a foundation for scientific and engineering computation in Common Lisp. It is designed not only to facilitate numerical computations, but to permit the use of numerical computation libraries and the interchange of data and procedures, whether foreign (non-Lisp) or Lisp libraries. It is named after the Antikythera mechanism, one of the oldest examples of a scientific computer known.

This is a teensy library that provides some functions to determine the mime-type of a file.

CL-SXML implements Oleg Kiselyov’s SXML, an S-expression-based rendering of the XML Infoset.

Various ASDF extensions such as attached test and documentation system, explicit development support, etc.

cl-quicklisp-stats is a system that fetches and performs basic operations on the Quicklisp download statistics.

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.

CL(x) xembed protocol implementation

NJSON aims to make it convenient for one to decode, encode, and process JSON data, in the minimum keystrokes/minutes possible.

NJSON is parser-independent, with existing Common Lisp JSON parsers being loadable as additional system. jzon is included by default, though. Conveniences that NJSON provides are:

• encode and decode as single entry points for JSON reading and writing, be it from streams/string/files, or from those.

• jget, jcopy, jkeys, and their aliases to manipulate the decoded objects' properties without the need to worry about the low-level details of how these values are decoded.

• jif, jwhen, jor, jand, and other macros mimicking Lisp ones, while using truth values of JSON-decoded data.

• jbind and jmatch macros to destructure and validate parsed JSON.

• njson/aliases package to nickname to j for all the forms conveniently accessible as j:get, j:copy, j:if etc.

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.

UCONS is a Common Lisp library providing unique conses. Unique conses are different from regular conses in that, in addition to their car and cdr, they maintain a table of past users. Also, the cdr of each ucons is restricted to other uconses or nil. Uconses are meant for those situations where even reusing regular conses (to avoid consing) is too computationally expensive.

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

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.

This is a bindings library to libout123 which allows easy cross-platform audio playback.

This package contains a few utility functions from the LispWorks library that are used in software such as ContextL.

Additional dolist style macros for Common Lisp, such as doalist, dohash, dolist*, doplist, doseq and doseq*.

BOOST-JSON is a simple JSON parsing library for Common Lisp.

This library provides modern file handling for Common Lisp, which avoids many of the pitfalls of pathnames.

This package provides a BNF parser in Common Lisp.
