This package provides a framework to unify arbitrary Common Lisp objects while constructing bindings for placeholders (unification variables) in a template sublanguage.

This package provides prototype Common Lisp implementations of TLS, RFC5246, ASN.1, x501,509, and PKCS1,3,5,8.

This package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

This package provides the terminal-size:size function to get the size of the terminal from Common Lisp.

IOlib is to be a better and more modern I/O library than the standard Common Lisp library. It contains a socket library, a DNS resolver, an I/O multiplexer(which supports select(2), epoll(4) and kqueue(2)), a pathname library and file-system utilities.

This library features a rectangle packer for sprite and texture atlases.

This package provides a grab bag of miscellaneous Common Lisp utilities.

This package provide a Common Lisp library for .zip-file reading and writing.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.

cl-pass is a password hashing and verification library.

This is a Common Lisp library providing various utilities.

This library contains code that implements Common Lisp hash tables.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

A Common Lisp library for generating a human-readable diff of two HTML documents.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

This Common Lisp library provides reader macros for concise expression of function partial application and composition.

This Common Lisp library provides optimized byte-swapping primitives. The library can change endianness of unsigned integers of length 1/2/4/8. Very useful in implementing various network protocols and file formats.

CL-FAD (for "Files and Directories") is a thin layer atop Common Lisp's standard pathname functions. It is intended to provide some unification between current CL implementations on Windows, OS X, Linux, and Unix. Most of the code was written by Peter Seibel for his book Practical Common Lisp.

This package contains a Gemini client library for Common Lisp. A subsystem offers an experimental GUI Gemini client.

This is a binding to the libyaml library. It's not meant as a full library for YAML, just a bare binding with a couple of utility macros. For a YAML parser and emitter using this, check out cl-yaml.

This is a packrat parser for Common Lisp. In addition to regular Packrat / Parsing Grammar / TDPL features ESRAP supports:

• dynamic redefinition of nonterminals

• inline grammars

• semantic predicates

• introspective facilities (describing grammars, tracing, setting breaks)

• left-recursive grammars

• functions as terminals

• accurate, customizable parse error reports

A Common Lisp client library for Apache Kafka.

Simple library to create temporary directories.

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