This is a very short and simple program, written in Common Lisp, that extends Common Lisp to embed shell code in a manner similar to Perl's backtick. It has been forked from SHELISP.

A hook, in the present context, is a certain kind of extension point in a program that allows interleaving the execution of arbitrary code with the execution of a the program without introducing any coupling between the two. Hooks are used extensively in the extensible editor Emacs.

In the Common LISP Object System (CLOS), a similar kind of extensibility is possible using the flexible multi-method dispatch mechanism. It may even seem that the concept of hooks does not provide any benefits over the possibilities of CLOS. However, there are some differences:

• There can be only one method for each combination of specializers and qualifiers. As a result this kind of extension point cannot be used by multiple extensions independently.

• Removing code previously attached via a :before, :after or :around method can be cumbersome.

• There could be other or even multiple extension points besides :before and :after in a single method.

• Attaching codes to individual objects using eql specializers can be cumbersome.

• Introspection of code attached a particular extension point is cumbersome since this requires enumerating and inspecting the methods of a generic function.

This library tries to complement some of these weaknesses of method-based extension-points via the concept of hooks.

Clamp is an attempt to bring the powerful, but verbose, language of Common Lisp up to the terseness of Arc.

There are two parts to Clamp. There is the core of Clamp, which implements the utilities of Arc that are easily converted from Arc to Common Lisp. The other part is the "experimental" part. It contains features of Arc that are not so easy to copy (ssyntax, argument destructuring, etc.).

A common lisp library that provides extensible function result caching based on arguments (an expanded form of memoization).

The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

This is a terminfo database front end in Common Lisp. The package provides a method for determining which capabilities a terminal (e.g. "xterm") has and methods to compile or put commands to a stream.

This is a Common Lisp library providing functions to read/write CSV from/to strings, streams and files.

mito-auth provides a mito mixin class for user authorization.

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

This is a system presenting a protocol for "file systems": things that present a collection of "files," which are things that have several attributes, and a central data payload. Most notably this includes the OS filesystem, but can also be used to address other filesystem-like things like archives, object stores, etc. in the same manner.

This is ZS3, a library for working with Amazon's Simple Storage Service (S3) and CloudFront service from Common Lisp.

GECO (Genetic Evolution through Combination of Objects) is an extensible, object-oriented framework for prototyping genetic algorithms in Common Lisp.

S-XML-RPC is an implementation of XML-RPC in Common Lisp for both client and server.

Moira is a library for monitoring and, if necessary, restarting long-running threads. In principle, it is like an in-Lisp process supervisor.

Event Emitter provides an event mechanism like Node.js for Common Lisp objects. It is mostly ported from Node.js events module.

trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

cl-xkb is a Common Lisp wrapper for the libxkbcommon keyboard handling library.

The library currently supports these xkb modules:

• Keysyms

• Library Context

• Include Paths

• Logging Handling

• Keymap Creation

• Keymap Components

• Keyboard State

• Compose and dead-keys support

charje.lambda-list can parse every kind of lambda list defined in the ANSI Common Lisp standard. Parsing yields only one object that has all the parsed parts of the lambda list inside. New kinds of lambda lists can be made too.

fast-http is a HTTP request/response protocol parser for Common Lisp.

Ironclad is a cryptography library written entirely in Common Lisp. It includes support for several popular ciphers, digests, MACs and public key cryptography algorithms. For several implementations that support Gray streams, support is included for convenient stream wrappers.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.

This library provides purely functional dictionaries and sets in Common Lisp based on the hash array-mapped trie data structure.

This is a general Freetype 2 wrapper for Common Lisp using CFFI. It's geared toward both using Freetype directly by providing a simplified API, as well as providing access to the underlying C structures and functions for use with other libraries which may also use Freetype.

This package provides a configuration library that adds the ability for Lem to manage packages within the user configuration directory.
