BST is a Common Lisp library for working with binary search trees that can contain any kind of values.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

This is a very simple color library for Common Lisp, providing:

• Types for representing colors in HSV, HSL, and RGB spaces.

• Simple conversion functions between the above types.

• Function printing colors to HEX, RGB, RGBA, and HSL.

• Predefined colors from X11, SVG, and GDK.

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.

EXTERNAL-PROGRAM enables running programs outside the Lisp process. It is an attempt to make the RUN-PROGRAM functionality in implementations like SBCL and CCL as portable as possible without sacrificing much in the way of power.

fast-websocket is an optimized low-level WebSocket protocol parser/composer.

Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.

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 library allows creation of hash tables with arbitrary test/hash functions, in addition to the test functions allowed by the standard (EQ, EQL, EQUAL and EQUALP), even in implementations that don't support this functionality directly.

With lispy syntax, shortcuts, and improvements, LASS aims to help you out in writing CSS quick and easy. LASS was largely inspired by SASS. LASS supports two modes, one being directly in your lisp code, the other in pure LASS files.

This package provides an embedded template engine for Common Lisp.

A heap-based priority queue whose first and foremost priority is speed.

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.

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 is a Common Lisp Markdown to HTML converter, using esrap for parsing, and grammar based on peg-markdown.

This library provides a macroexpand-all function that calls the implementation specific equivalent.

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.

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

cl-cron is a simple tool that provides cron like facilities directly inside of Common Lisp.

This package provides a Common Lisp library for fetching and parsing RSS feeds data via HTTP. Currently, it supports RSS versions 0.90, 0.91, and 0.92 as well as RSS version 2.

This is a YAML parser and emitter for Common Lisp built on top of libyaml.

This package provides a JSON-RPC 2.0 server/client for Common Lisp.

This Common Lisp library provides functions for lzip (LZMA) compression/decompression using bindings to the lzlib C library.

CL-DISKSPACE is a Common Lisp library to list disks with the command line tool df and get disk space information using statvfs.
