This library is intended to solve the problem of source tracking for Common Lisp code.

By "source tracking", it is meant that code elements that have a known origin in the form of a position in a file or in an editor buffer are associated with some kind of information about this origin.

Since the exact nature of such origin information depends on the Common Lisp implementation and the purpose of wanting to track that origin, the library does not impose a particular structure of this information. Instead, it provides utilities for manipulating source code in the form of what is called concrete syntax trees (CSTs for short) that preserve this information about the origin.

This system implements a general definitions introspection library. It gives you the ability to retrieve definitions or bindings associated with designators such as symbols, packages, and names in general. For instance, it allows you to retrieve all function, type, variable, method, etc. definitions of a symbol.

Implementation of a set-like data structure with constant time addition, removal, and random selection.

This is a Common Lisp implementation of the Encoding for Robust Immutable Storage specification (ERIS).

This package provides a recursive-descent parser DSL for Common Lisp. It's intended as a simpler alternative to parser generators.

Dufy is a library for exact color manipulation and conversion in various color spaces, which supports many color models.

This Common Lisp library implements the quoted-printable encoding as described in RFC 2045 (see http://tools.ietf.org/html/rfc2045).

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/.

This library provides a uniform API, as specified in Common Lisp the Language 2, for accessing information about variable and function bindings from implementation-defined lexical environment objects. All major Common Lisp implementations are supported, even those which don't support the CLTL2 environment access API.

Linedit is a readline-style library written in Common Lisp that provides customizable line-editing for Common Lisp programs.

This library is a Common Lisp port of all the constants from the event codes header file found on Linux and FreeBSD.

CLX-TrueType is pure common lisp solution for antialiased TrueType font rendering using CLX and XRender extension.

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

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.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

This is a c2ffi-based wrapper generator for Common Lisp.

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

CLML (Common Lisp Machine Learning) is a high performance and large scale statistical machine learning package

A mixture of features from eRuby and HTML::Template. You could name it "Yet Another LSP" (LispServer Pages) but it's a bit more than that and not limited to a certain server or text format.

This is a string/octets parser library for Common Lisp with speed and readability in mind. Unlike other libraries, the code is not a pattern-matching-like, but a char-by-char procedural parser.

ISSR core provides functions and variables for ISSR server modules so that different servers can behave similarly. The most important features are Document Object Model differencing to generate instructions to update a DOM, and DOM cleaning, to ensure that all remote DOMs are the same.

Sycamore is a fast, purely functional data structure library in Common Lisp. If features:

• Fast, purely functional weight-balanced binary trees.

• Leaf nodes are simple-vectors, greatly reducing tree height.

• Interfaces for tree Sets and Maps (dictionaries).

• Ropes.

• Purely functional pairing heaps.

• Purely functional amortized queue.

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.
