cl-annot is an general annotation library for Common Lisp.

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

This library is part of NUMCL. It provides a macro SPECIALIZED that performs a Julia-like dispatch on the arguments, lazily compiling a type-specific version of the function from the same code. The main target of this macro is speed.

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.

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

This package provides the LOCAL-TIME extensions for the cl-postgres ASDF system of postmodern.

Common Lisp comes with quite some functions to compare objects for equality, yet none is applicable in every situation and in general this is hard, as equality of objects depends on the semantics of operations on them. As consequence, users find themselves regularly in a situation where they have to roll their own specialized equality test.

This module provides one of many possible equivalence relations between standard Common Lisp objects. However, it can be extended for new objects through a simple CLOS protocol. The rules when two objects are considered equivalent distinguish between mutating and frozen objects. A frozen object is promised not to be mutated in the future in a way that operations on it can notice the difference.

We have chosen to compare mutating objects only for identity (pointer equality), to avoid various problems. Equivalence for frozen objects on the other hand is established by recursing on the objects' constituent parts and checking their equivalence. Hence, two objects are equivalent under the OBJECT= relation, if they are either identical, or if they are frozen and structurally equivalent, i.e. their constituents are point-wise equivalent.

Since many objects are potentially mutable, but are not necessarily mutated from a certain point in their life time on, it is possible to promise to the equivalence relation that they remain frozen for the rest of their life time, thus enabling coarser equivalence than the often too fine-grained pointer equality.

Quickproject provides a quick way to make a Common Lisp project. After creating a project, it extends the ASDF registry so the project may be immediately loaded.

simple-neural-network is a Common Lisp library for creating, training and using basic neural networks. The networks created by this library are feedforward neural networks trained using backpropagation.

This package makes it possible to name classes by lists of symbols instead of symbols.

exit-hooks provides a portable way to automatically call some user-defined function when exiting Common Lisp (both quit from the REPL or a kill in a shell). Like atexit in C and Python or Java’s Runtime.addShutdownHook(). It currently supports SBCL, CCL, ECL, ABCL, Allegro CL, clisp and CMUCL. Before exit-hooks, there was no portable way of doing so and no staightforward way to use an exit hook on ABCL. It can be used for tasks like parmenantly save something when exiting Lisp.

The 3d-math library implements types, operators, and algorithms commonly used in math for 2D and 3D graphics. It supersedes and combines the prior libraries 3d-vectors, 3d-matrices, 3d-quaternions, and 3d-transforms. The new API is largely but not entirely backwards compatible, and adds new functionality.

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

This package provides Common Lisp bindings for libev.

This is a library for quaternions. It contains most of the quaternion operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable. It also tries to be efficient where plausible. Each quaternion is made up of floats, which by default are single-floats, as they do not require value boxing on most modern systems and compilers.

This package defines a Common Lisp package, :elements, with an ELEMENT structure and a number of functions to search the periodic table.

This library is an implementation of the XML Path Language (XPath) Version 1.0.

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 library converts the elements from GObject Introspection into Common Lisp-style definitions, based on cl-gobject-introspection.

The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

Often times we need to destructure a form definition in a Common Lisp macro. This library provides a set of simple utilities to help with that.

Eager Future2 is a Common Lisp library that provides composable concurrency primitives that unify parallel and lazy evaluation, are integrated with the Common Lisp condition system, and have automatic resource management.

This library allows you to define custom indentation hints for your macros if the one recognised by SLIME automatically produces unwanted results.

Chunga implements streams capable of chunked encoding on demand as defined in RFC 2616.
