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.

ContextL is a CLOS extension for Context-Oriented Programming (COP).

Find overview of ContextL's features in an overview paper: http://www.p-cos.net/documents/contextl-soa.pdf. See also this general overview article about COP which also contains some ContextL examples: http://www.jot.fm/issues/issue_2008_03/article4/.

PP-TOML is a Common Lisp library for parsing strings in the TOML configuration file format. It implements only the 0.1.0 specification of TOML.

This package provides a UTF-8 string input stream over a binary stream for Common Lisp.

Eazy-Gnuplot is a Common Lisp interface to gnuplot which eschews CFFI, CLOS and structures. It communicates with gnuplot via *standard-output*, and users can plot data by printing to that stream.

A small collection of common lisp macros to make collecting values easier.

Domain specific language for producing TeX documents with Common Lisp.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

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).

Cl-async is a library for general purpose, non-blocking programming in Common Lisp. It uses the libuv library as backend.

cl-numerical-utilities is a collection of packages useful in numerical applications, each big enough to be its own package, but too small to split out into a separate ASDF system.

This is a Common Lisp library for reading PNG images.

Various ASDF extensions such as attached test and documentation system, explicit development support, etc.

April compiles a subset of the APL programming language into Common Lisp. Leveraging Lisp's powerful macros and numeric processing faculties, it brings APL's expressive potential to bear for Lisp developers. Replace hundreds of lines of number-crunching code with a single line of APL.

Periods is a Common Lisp library providing a set of utilities for manipulating times, distances between times, and both contiguous and discontiguous ranges of time.

This package provides functions to encode or decode byte vectors or byte streams using the Z85 format, which is a base-85 encoding used by ZeroMQ.

This package provides a concise, intuitive and flexible macro for trivial lambdas that eschews explicit naming of parameter variables in favor of positional references, with support for a used or ignored &rest parameter and automatic declaration of ignored parameters when logical gaps are left in the positional references. Further convenience features are provided.

Duologue is high-level interaction library for Common Lisp. It features coloured printing via cl-ansi-text and readline completion.

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.

This package implements a simple interface for using WebSockets via Common Lisp.

This package provides a framework to unify arbitrary Common Lisp objects while constructing bindings for placeholders (unification variables) in a template sublanguage.

This is a lisp implementation of the Open Sound Control protocol (or more accurately “data transport specification” or “encoding”). The code should be close to ANSI standard common lisp and provides self contained code for encoding and decoding of OSC data, messages, and bundles.

This library is a fork of SSL-CMUCL. The original SSL-CMUCL source code was written by Eric Marsden and includes contributions by Jochen Schmidt. Development into CL+SSL was done by David Lichteblau.

This package provides an interface to the gnuplot plotting utility. The intention of the API is to resemble to some of the plot commands of octave or matlab.
