This library is a redefinition of the standard Common Lisp package that includes a number of renames and shadows.

This library extracts the TLD (Top Level Domain) from domains. The information is taken from https://publicsuffix.org.

This package contains an implementation of RFC 2388, which is used to process form data posted with HTTP POST method using enctype "multipart/form-data".

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.

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.

This is a Common Lisp library providing a unified way to work with package locks across supported Common Lisp implementations.

This is a (currently) brief but usable wrap for SDL2_image.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

This Common Lisp package offers an implementation of the 32-bit variant of MurmurHash3 (https://github.com/aappleby/smhasher), a fast non-crytographic hashing algorithm.

Pileup is a portable, performant, and thread-safe binary heap for Common Lisp.

This package provides CFFI bindings to the libflac audio library for Common Lisp.

concurrent-hash-tables is a Common Lisp portability library wrapping some implementations of concurrent hash tables which do not have to be entirely locked in their operation, including 42nd-at-threadmill, luckless, and a fallback, segmented hash table.

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

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

A modern and consistent Common Lisp string manipulation library that focuses on modernity, simplicity and discoverability: (str:trim s) instead of (string-trim '(#\Space ...) s)), or str:concat strings instead of an unusual format construct; one discoverable library instead of many; consistency and composability, where s is always the last argument, which makes it easier to feed pipes and arrows.

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

This package is a simple date and time library.

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

This package provides a canonical way of converting generalized booleans to booleans.

Coalton is a dialect of ML embedded in Common Lisp. It emphasizes practicality and interoperability with Lisp, and is intended to be a DSL that allows one to gradually make their programs safer.

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.

A collection of Common Lisp utility functions and macros mostly not found in other utility packages.

This library implements special functions and has a focus on high accuracy double-float calculations using the latest algorithms.
