Xmls is a self-contained, easily embedded parser that recognizes a useful subset of the XML spec. It provides a simple mapping from XML to Lisp structures or s-expressions and back.

Aims to be fast, modular, cachable and concise. It does so by defining each tag as a macro which expands to code printing the respective HTML source. Also employs a DSL for element attributes.

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.

This is a utility library providing access to the mmap family of functions in a portable way. It allows you to directly map a file into the address space of your process without having to manually read it into memory sequentially. Typically this is much more efficient for files that are larger than a few Kb.

Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

This library validates superclasses according to a simple substitution model, thereby greatly simplifying the definition of class mixins.

parse-number is a library of functions for parsing strings into one of the standard Common Lisp number types without using the reader. parse-number accepts an arbitrary string and attempts to parse the string into one of the standard Common Lisp number types, if possible, or else parse-number signals an error of type invalid-number.

This system implements binding threading macros -- a kind of threading macros with different semantics than classical, Clojure core threading macros or their extension, swiss-arrows. Two Common Lisp implementations of those are arrows and arrow-macros.

This system is a fork of arrows with changes in semantics that make it impossible to merge back upstream.

Infix-Math is a library that provides a special-purpose syntax for transcribing mathematical formulas into Lisp.

Drakma is a full-featured HTTP client implemented in Common Lisp. It knows how to handle HTTP/1.1 chunking, persistent connections, re-usable sockets, SSL, continuable uploads, file uploads, cookies, and more.

This is a Common Lisp autowrapping facility for quickly creating clean and lean bindings to C libraries.

A Common Lisp library implementing a few different kinds of queues:

• Bounded and unbounded FIFO queues.

• Lossy bounded FIFO queues that drop elements when full.

• Unbounded random-order queues that use less memory than unbounded FIFO queues.

Additionally, a synchronization wrapper is provided to make any queue conforming to the jpl-queues API thread-safe for lightweight multithreading applications. (See Calispel for a more sophisticated CL multithreaded message-passing library with timeouts and alternation among several blockable channels.)

PARSER-COMBINATORS is a library implementing monadic parser combinators in Common Lisp, similar in concept to Haskell Parsec system.

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

This is a collection of useful helper modules and standard implementations for Radiance interfaces.

This package provides an enhanced EVAL-WHEN macro that supports a shorthand for (eval-when (:compile-toplevel :load-toplevel :execute) ...), addressing concerns about verbosity.

This Common Lisp library implements object prevalence (see https://en.wikipedia.org/wiki/System_prevalence). It allows for (de)serializing to and from s-exps as well as XML. Serialization of arbitrary classes and cyclic data structures are supported.

Simple color library for Common Lisp.

cl-pass is a password hashing and verification library.

This package provides a standard way to canonicalize slot values.

This is a Common Lisp library that implements the 9p network filesystem protocol.

cl-num-utils implements simple numerical functions for Common Lisp, including:

• num=, a comparison operator for floats

• simple arithmeric functions, like sum and l2norm

• elementwise operations for arrays

• intervals

• special matrices and shorthand for their input

• sample statistics

• Chebyshev polynomials

• univariate rootfinding

This library contains a collection of machine learning algorithms for online linear classification written in Common Lisp.

This project is meant to provide tools for internationalizing Common Lisp programs.

One important aspect of internationalization is of course the language used in error messages, documentation strings, etc. But with this project we provide tools for all other aspects of internationalization as well, including dates, weight, temperature, names of physical quantities, etc.
