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 is a Common Lisp library for processing data found in dBase III database files (dbf and db3 files).

Eclector is a portable Common Lisp reader that is highly customizable, can recover from errors and can return concrete syntax trees.

In contrast to many other reader implementations, eclector can recover from most errors in the input supplied to it and continue reading. This capability is realized as a restart.

It can also produce instances of the concrete syntax tree classes provided by the concrete syntax tree library.

cl-incless implements print-object methods for many standard classes.

The cl-data-lens library provides a language for expressing data manipulations as the composition of more primitive operations.

This is a utility kit for functionality related to OpenGL. It provides the following:

• kit.glm: This re-exports sb-cga and mathkit for convenience.

• kit.gl.shader: This provides shader dictionary and compilation functionality similar to what was originally found in sdl2kit.

• kit.gl.vao: This provides an interface for Vertex Array Objects.

This library validates superclasses according to a simple substitution model, thereby greatly simplifying the definition of class mixins.

This package provides a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

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

This is a Common Lisp library providing a set of macros for generating lexical analyzers automatically. The lexers generated using cl-lex can be used with cl-yacc.

UCONS is a Common Lisp library providing unique conses. Unique conses are different from regular conses in that, in addition to their car and cdr, they maintain a table of past users. Also, the cdr of each ucons is restricted to other uconses or nil. Uconses are meant for those situations where even reusing regular conses (to avoid consing) is too computationally expensive.

SPECIALIZATION-STORE system provides a new kind of function, called a store function, whose behavior depends on the types of objects passed to the function.

cl-tar is a Common Lisp library providing a high-level interface for interacting with tar archives.

ASDF-FLV provides support for file-local variables through ASDF. A file-local variable behaves like *PACKAGE* and *READTABLE* with respect to LOAD and COMPILE-FILE: a new dynamic binding is created before processing the file, so that any modification to the variable becomes essentially file-local.

In order to make one or several variables file-local, use the macros SET-FILE-LOCAL-VARIABLE(S).

The GTWIWTG library (Generators The Way I Want Them Generated -- technically not generators, but iterators) is meant to be small, explorable, and understandable.

Chunga implements streams capable of chunked encoding on demand as defined in RFC 2616.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

This package provides first-class global environments for Common Lisp.

The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

This is a Common Lisp wrapper for interacting with the Redis data structure store.

Nodgui (No Drama GUI) is a Common Lisp binding for the Tk GUI toolkit. It also provides a few additional widgets more than the standard Tk ones.

This Common Lisp library focuses on the small set of basic color manipulations (lightening, compliments, etc.) you might use to generate a color palette for a GUI or web page.

3D-VECTORS is a library for vector math in 3D space. It contains most of the vector operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable.

HTTP-Body parses HTTP POST data and returns POST parameters. It supports application/x-www-form-urlencoded, application/json, and multipart/form-data.
