TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

This package provides a configuration library that adds the ability for Lem to manage packages within the user configuration directory.

CL-STORE is a portable serialization package which should give you the ability to store all Common Lisp data types into streams.

This library is an SDL wrapper as part of an umbrella project that provides cross-platform packages for building large, interactive applications in Common Lisp.

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.

This package provides Common Lisp bindings to GSSAPI, which is designed to provide a standard API to authentication services. The API itself is generic, and the system can provide different underlying implementations. The most common one is Kerberos, which has several implementations, the most common of which is probably Active Directory.

CL-ANA is a data analysis library in Common Lisp providing tabular and binned data analysis along with nonlinear least squares fitting and visualization.

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

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

This is a Common Lisp library providing various utilities.

This package provides functions to emit XML, with some complexity for handling indentation. It can be used to produce all sorts of useful XML output; it has an RSS 2.0 emitter built in, so you can make RSS feeds trivially.

This package provides a DSL for array slices in Common Lisp.

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

Just wrap your Common Lisp function in this macro call and it will be optimized for tail recursion. You will be warned if the function is not tail recursive.

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

This is a purely math-related utility kit, providing functions which can be useful for games, 3D, and GL in general.

Often times we need to destructure a form definition in a Common Lisp macro. This library provides a set of simple utilities to help with that.

This library contains code that implements Common Lisp hash tables.

This package provides a KDL reader/writer for Common Lisp.

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.

This is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

Conium is a portability library for debugger- and compiler-related tasks in Common Lisp. It is fork of SWANK-BACKEND.

This package contains a support library for other hu.dwim systems.

CL-Yacc is a LALR(1) parser generator for Common Lisp, similar in spirit to AT&T Yacc, Berkeley Yacc, GNU Bison, Zebu, lalr.cl or lalr.scm.

CL-Yacc uses the algorithm due to Aho and Ullman, which is the one also used by AT&T Yacc, Berkeley Yacc and Zebu. It does not use the faster algorithm due to DeRemer and Pennello, which is used by Bison and lalr.scm (not lalr.cl).
