fmt provides an alternative to the Common Lisp format function by utilizing s-expressions for formatting directives instead of control strings.

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

This is a Common Lisp utilities library originating from the Zombie Raptor game engine project.

iterate is an iteration construct for Common Lisp. It is similar to the CL:LOOP macro, with these distinguishing marks:

• it is extensible,

• it helps editors like Emacs indent iterate forms by having a more lisp-like syntax, and

• it isn't part of the ANSI standard for Common Lisp.

This library allows macro writers to provide better feedback to macro users when errors are signaled during macroexpansion. It uses the compiler's concept of a source-form to report where the error or warning is located.

cl-pass is a password hashing and verification library.

CL-DATA-STRUCTURES is a Common Lisp library providing a portable collection of mutable and immutable data structures (dictionaries, sets, queues, sequences) and algorithms.

This is a collection of common cryptography functions 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.

CLSS is a DOM traversal engine based on CSS selectors. It makes use of the Plump-DOM and is used by lQuery.

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

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

This library lets you build a metaclass which in turn lets you specify extra slot options in its classes. Options may be easily inspected and custom inheritance may be set up. The Meta-Object Protocol (MOP) is used for the implementation - through closer-mop. Some convenience function for processing slot options are also available.

Possible use case: you want to automatically set up some definitions based on some slots, but you want to have control over it right in the class definition.

DATA-SIFT is a Common Lisp data validation and transformation library inspired by cl-data-format-validation and WTForms validators.

This is a Common Lisp library providing a unified way to work with package locks across supported Common Lisp implementations.

This is a Common Lisp library to build and compose SXQL queries dynamically.

This library provides almost the same code as used inside Quicklisp for drawning progress bars

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

This is a Common Lisp library providing RFC 3986 percent-encoding.

This package provides a statistical computing environment for Common Lisp.

This Common Lisp package offers an implementation of the 32-bit variant of MurmurHash3 (https://github.com/aappleby/smhasher), a fast non-crytographic hashing algorithm.

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