This is a portable Universal Resource Identifier library for Common Lisp programs. It parses URI according to the RFC 2396 specification.

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

cl-rucksack is a persistence library based on Arthur Lemmens' Rucksack with some enhancements.

The server part of AllegroServe can be used either as a standalone web server or a module loaded into an application to provide a user interface to the application. AllegroServe's proxy ability allows it to run on the gateway machine between some internal network and the Internet. AllegroServe's client functions allow Lisp programs to explore the web.

The Type-Templates library allows you to define types and “template functions” that can be expanded into various type-specialized versions to eliminate runtime dispatch overhead. It was specifically designed to implement low-level numerical data types and functionality.

This package provides Common Lisp FFI bindings for xkbcommon (libxkbcommon) using cffi-grovel.

This package provides Common Lisp bindings for libev.

CLX-TrueType is pure common lisp solution for antialiased TrueType font rendering using CLX and XRender extension.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

This Common Lisp library provides a series data structure much like a sequence, with similar kinds of operations. The difference is that in many situations, operations on series may be composed functionally and yet execute iteratively, without the need to construct intermediate series values explicitly. In this manner, series provide both the clarity of a functional programming style and the efficiency of an iterative programming style.

This package provides a trivial line-input library for VT-like terminals.

Filtered functions provide an extension of CLOS generic function invocation that add a simple preprocessing step before the actual method dispatch is performed and thus enable the use of arbitrary predicates for selecting and applying methods. See http://www.p-cos.net/documents/filtered-dispatch.pdf for a paper that introduces and explains filtered functions in detail.

This is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

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

(X)HTMLambda is yet another (X)HTML library which emphasizes programmability and user-friendliness. Each (X)HTML element is a structured object and pretty-printing of (X)HTML trees is well defined to provide properly indented human-readable output even for complex recursive arrangements.

Agnostic Lizard is a portable implementation of a code walker and in particular of the macroexpand-all function (and macro) that makes a best effort to be correct while not expecting much beyond what the Common Lisp standard requires.

It aims to be implementation-agnostic and to climb the syntax trees.

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

bubble-operator-upwards is a function that bubbles an operator upwards in a form, demultiplexing all alternative branches by way of cartesian product.

This package provides a library to open a web browser to a URL.

Fast-io is about improving performance to octet-vectors and octet streams (though primarily the former, while wrapping the latter).

This library strives to provide a portable TCP/IP and UDP/IP socket interface for as many Common Lisp implementations as possible, while keeping the abstraction and portability layer as thin as possible.

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

This a Common Lisp library to convert geographic coordinates between latitude/longitude and MGRS.
