This package provides Common Lisp bindings to POSIX message queue, an IPC method that is easy to use and quick to setup.

CIEL is a ready-to-use collection of libraries providing: a binary, to run CIEL scripts; a simple full-featured REPL for the terminal; a Lisp library and a core image.

Lack is a Common Lisp library which allows web applications to be constructed of modular components. It was originally a part of Clack, however it's going to be rewritten as an individual project since Clack v2 with performance and simplicity in mind.

This package provides a general-purpose connection pooling library for Common Lisp.

On Cliki.net <http://www.cliki.net/Common%20Lisp%20Utilities>, there is a collection of Common Lisp Utilities, things that everybody writes since they're not part of the official standard. There are some very useful things there; the only problems are that they aren't implemented as well as you'd like (some aren't implemented at all) and they aren't conveniently packaged and maintained. It takes quite a bit of work to carefully implement utilities for common use, commented and documented, with error checking placed everywhere some dumb user might make a mistake.

This package provides a small utility library to open a thing (usually a file or URL) in an appropriate handler (usually an external file manager or browser).

KMRCL is a collection of utilities used by a number of Kevin Rosenberg's Common Lisp packages.

This library provides a WebSocket server and client implementation for Common Lisp.

This library is a little experiment in reducing verbosity in Common Lisp, inspired by BODOL (https://github.com/bodil/BODOL).

This library provides a WebSockets extension for the Huchentoot web server.

This library provides a drop-in replacement function for cl:documentation that supports multiple docstrings per-language, allowing you to write documentation that can be internationalised.

F2cl is a Common Lisp library that can convert Fortran 77 code into Common Lisp code.

This library generates sdf (https://steamcdn-a.akamaihd.net/apps/valve/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf), psdf and msdf (https://github.com/Chlumsky/msdfgen/files/3050967/thesis.pdf) atlases.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

This package provides a JSON Pointer (RFC6901) implementation for Common Lisp. This library aims to be independent from any JSON libraries (as much as possible).

This is a small OS portability library to retrieve and set file attributes not supported by the Common Lisp standard functions.

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

This library introduces fast generic functions, i.e. functions that behave just like regular generic functions, except that the can be sealed on certain domains. If the compiler can then statically detect that the arguments to a fast generic function fall within such a domain, it will perform a variety of optimizations.

cl-gopher is a Common Lisp library for interacting with the Gopher protocol.

It is suitable for building both clients and servers, and provides a sample client.

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.

This a Common Lisp library to parse HTML5 documents.

This package provides a Common Lisp library for defining OpenGL shader programs. There are also functions for referencing shader programs by name, querying for basic information about them, modifying uniform variables throughout the lifecycle of an OpenGL application, and managing certain OpenGL buffer object types (UBO, SSBO currently).

This library provides a wrapper type for secret values, to reduce the risk of accidentally revealing them.

Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.
