This package parses and prints dates in RFC-1123 format.

This package provides a Common Lisp system which has only one function to return the CPU count of the current system.

CLSS is a DOM traversal engine based on CSS selectors. It makes use of the Plump-DOM and is used by lQuery.

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.

BST is a Common Lisp library for working with binary search trees that can contain any kind of values.

This is a coroutine library for Common Lisp implemented using the continuations of the cl-cont library.

This package is a simple date and time library.

Simple library to create temporary directories.

This package provides a Common Lisp system implementing event bus.

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.

binascii is a Common Lisp library for converting binary data to ASCII text of some kind. Such conversions are common in email protocols (for encoding attachments to support old non-8-bit clean transports) or encoding binary data in HTTP and XML applications. binascii supports the encodings described in RFC 4648: base64, base32, base16, and variants. It also supports base85, used in Adobe's PostScript and PDF document formats, and a variant called ascii85, used by git for binary diff files.

This package provides a Common Lisp templating system based on Python Django with a syntax similar to Python Jinja2.

Bind extends the idea of of let and destructing to provide a uniform syntax for all your accessor needs. It combines let, destructuring-bind, with-slots, with-accessors, structure editing, property or association-lists, and multiple-value-bind and a whole lot more into a single form.

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

cl-libxml2 is high-level Common Lisp wrapper around the libxml2 and libxslt libraries.

• Interfaces for tree manipulation (like cxml-stp).

• Interface for HTML 4.0 non-validating parsers.

• Specific APIs to process HTML trees, especially serialization.

• XPath API.

• XSLT API.

• Custom URL resolvers.

• XPath extension functions.

• XSLT extension elements.

• Translates libxml2 and libxslt errors to Lisp conditions.

• Extends the Common Lisp iterate library with custom drivers for child nodes enumeration, etc.

• The XFACTORY system provides a simple and compact syntax for XML generation.

This is a backend for the linear-programming Common Lisp library using the GNU Linear Programming Kit (GLPK) library.

Dexador is yet another HTTP client for Common Lisp with neat APIs and connection-pooling. It is meant to supersede Drakma.

This package provides an interface to the gnuplot plotting utility. The intention of the API is to resemble to some of the plot commands of octave or matlab.

Cluffer is a library for representing the buffer of a text editor. As such, it defines a set of CLOS protocols for client code to interact with the buffer contents in various ways, and it supplies different implementations of those protocols for different purposes.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

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

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.

Plump is a parser for HTML/XML-like documents, focusing on being lenient towards invalid markup. It can handle things like invalid attributes, bad closing tag order, unencoded entities, inexistent tag types, self-closing tags and so on. It parses documents to a class representation and offers a small set of DOM functions to manipulate it. It can be extended to parse to your own classes.
