This is a library for access to atomic operation primitives such as compare-and-swap. It aims to be a rather thin layer over what the implementations offer.

This is a Common Lisp wrapper for interacting with the Redis data structure store.

This package provides an ANSI CL adaptation of the SBCL mailbox utility.

This is a websocket server for Common Lisp using usockets to be portable between implementations and operating systems. It has a programming interface that allows for multiple websocket apps per server using Common Lisp keywords for different websocket events. It has useful restarts and customizable errors.

This Common Lisp library implements a parser generator for the ABNF grammar format as described in RFC2234. The generated parser is a regular expression scanner provided by the cl-ppcre lib, which means that we can't parse recursive grammar definition. One such definition is the ABNF definition as given by the RFC. Fortunately, as you have this lib, you most probably don't need to generate another parser to handle that particular ABNF grammar.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

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

SB-CGA is a computer graphics algebra library for Common Lisp.

Despite the prefix it is actually portable - but optimizations that make it fast (using SIMD instructions) are currently implemented for SBCL/x86-64 only.

This is a Common Lisp package for hash table creation with flexible, extensible initializers.

ARNESI is Common Lisp utilities library similar to ALEXANDRIA, ANAPHORA or GOLDEN-UTILS.

atomichron is a Common Lisp library which implements a time meter which tracks how many times a form is evaluated, and how long evaluation takes. It uses atomic instructions so that meters will present correct results in the presence of multiple threads, while trying to minimize synchronization latency.

Croatoan provides high-level Common Lisp CLOS bindings for the ncurses terminal library.

Dynamic-Classes helps to ease the prototyping process by bringing dynamism to class definition.

QURI (pronounced "Q-ree") is yet another URI library for Common Lisp. It is intended to be a replacement of PURI.

This package allows flexible specification of package-local preferences.

S-XML is a simple XML parser implemented in Common Lisp. This XML parser implementation has the following features:

• It works (handling many common XML usages).

• It is very small (the core is about 700 lines of code, including comments and whitespace).

• It has a core API that is simple, efficient and pure functional, much like that from SSAX (see also http://ssax.sourceforge.net).

• It supports different DOM models: an XSML-based one, an LXML-based one and a classic xml-element struct based one.

• It is reasonably time and space efficient (internally avoiding garbage generatation as much as possible).

• It does support CDATA.

• It should support the same character sets as your Common Lisp implementation.

• It does support XML name spaces.

This XML parser implementation has the following limitations:

• It does not support any special tags (like processing instructions).

• It is not validating, even skips DTD's all together.

zsort is a collection of portable sorting algorithms. Common Lisp provides the sort and stable-sort functions but these can have different algorithms implemented according to each implementation. Also, the standard sorting functions might not be the best for a certain situations. This library aims to provide developers with more options.

ARNESI is Common Lisp utilities library similar to ALEXANDRIA, ANAPHORA or GOLDEN-UTILS.

Parseq (pronounced parsec) is a parsing library for common lisp. It can be used for parsing lisp's sequences types: strings, vectors (e.g. binary data) and lists. Furthermore, parseq is able to parse nested structures such as trees (e.g. lists of lists, lists of vectors, vectors of strings).

Parseq uses parsing expression grammars (PEG) that can be defined through a simple interface. Extensions to the standard parsing expressions are available. Parsing expressions can be parameterised and made context aware. Additionally, the definition of each parsing expression allows the arbitrary transformation of the parsing tree.

The library is inspired by Esrap and uses a very similar interface. No code is shared between the two projects, however. The features of Esrap are are mostly included in parseq and complemented with additional, orthogonal features. Any resemblance to esrap-liquid is merely coincidental.

VAS-STRING-METRICS provides the Jaro, Jaro-Winkler, Soerensen-Dice, Levenshtein, and normalized Levenshtein string distance/similarity metrics algorithms.

This package provides an ASN.1 encoder/decoder for Common Lisp.

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

This library allows you to implement and enforce proper finalization of compile-time constructs while building Lisp source files.

It produces two systems: asdf-finalizers and list-of.

Cl-async is a library for general purpose, non-blocking programming in Common Lisp. It uses the libuv library as backend.
