With static-vectors, you can create vectors allocated in static memory.

YASON is a Common Lisp library for encoding and decoding data in the JSON interchange format.

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.

My Way is a Sinatra-compatible URL routing library.

This is a task scheduling framework for Common Lisp.

This library implements special functions and has a focus on high accuracy double-float calculations using the latest algorithms.

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

CL-STRFTIME is a Common Lisp compiler for the strftime “language.”

Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.

Inquisitor is a cross-implementation library providing encoding/end-of-line detection and external-format abstraction for Common Lisp.

Provides a simple way of directing output to a stream according to the concise and intuitive semantics of FORMAT's stream argument.

simple-routes is a simple Common Lisp RESTful routing facility on top of Hunchentoot.

HTML-TEMPLATE is a Common Lisp library which can be used to fill templates with arbitrary (string) values at runtime. The result does not have to be HTML.

It is loosely modeled after the Perl module HTML::Template and partially compatible with a its syntax, though both libraries contain some extensions that the other does not support.

HTML-TEMPLATE translates templates into efficient closures which can be re-used as often as needed. It uses a cache mechanism so you can update templates while your program is running and have the changes take effect immediately.

This lisp library handles physical quantities which consist of

• value / magnitude

• uncertainty / error

• unit

where the type of the value can be any subtype of real. For the uncertainty, both absolute and relative values are possible. Combinations of lisp symbols or strings are used to describe units. User defined units including abbreviations and prefixes are supported. Error propagation and unit checking is performed for all defined operations.

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

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

QMyND, the QITAB MySQL Native Driver, is a MySQL client library that directly talks to a MySQL server in its native network protocol.

It's a part of QITAB umbrella project.

This library contains an implementation of interfaces and implementations. They're sometimes called protocols in other languages. Broadly speaking, an interface is some collection of function prototypes that a valid implementation must implement.

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.

CL-PUNCH is a Scala-like anonymous lambda literal.

GENERIC-COMPARABILITY is an implementation of CDR-8 (Generic Equality and Comparison for Common Lisp). CDR-8 provides an interface for the EQUALS function, which is defined as a general equality predicate, as well as a set of ordering (COMPARE) functions for comparison. The semantics are described in the CDR-8 standard.

Common Lisp ships with a set of powerful built in data structures including the venerable list, full featured arrays, and hash-tables. CL-containers enhances and builds on these structures by adding containers that are not available in native Lisp (for example: binary search trees, red-black trees, sparse arrays and so on), and by providing a standard interface so that they are simpler to use and so that changing design decisions becomes significantly easier.

The variates package provides portable random number generation as well as numerous distributions.
