dbi is a Common Lisp library providing a database independent interface for MySQL, PostgreSQL and SQLite.

This package provides a functionality augmenting Hunchentoot error pages and logs with request and session information.

cl-gserver is a 'message passing' library / framework with actors similar to Erlang or Akka. It supports creating reactive systems for parallel computing and event based message handling.

BOOST-PARSE is a simple token parsing library for Common Lisp.

Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

cl-charms is an interface to libcurses in Common Lisp. It provides both a raw, low-level interface to libcurses via CFFI, and a more higher-level lispier interface.

This is a pure Common Lisp library to create, transform and render anti-aliased vectorial paths.

This library provides a WebSockets extension for the Huchentoot web server.

This project is meant to provide tools for internationalizing Common Lisp programs.

One important aspect of internationalization is of course the language used in error messages, documentation strings, etc. But with this project we provide tools for all other aspects of internationalization as well, including dates, weight, temperature, names of physical quantities, etc.

This package provides a PEM (Privacy-Enhanced Mail) parser for Common Lisp.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

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

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.

cl-tar-file is a Common Lisp library that allows reading from and writing to various tar archive formats. Currently supported are the POSIX ustar, PAX (ustar with a few new entry types), GNU, and v7 (very old) formats.

This library is rather low level and is focused exclusively on reading and writing physical tar file entries using streams. Therefore, it contains no functionality for automatically building archives from a set of files on the filesystem or writing the contents of a file to the filesystem. Additionally, there are no smarts that read multiple physical entries and combine them into a single logical entry (e.g., with PAX extended headers or GNU long link/path name support). For a higher-level library that reads and writes logical entries, and also includes filesystem integration, see cl-tar.

This package provides functions for generating lorem ipsum text.

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.

BOOST-LEXER is a tokenizer for Common Lisp that makes heavy use of BOOST-RE.

This is a Common Lisp implementation of the MessagePack (http://msgpack.org/) serialization/deserialization format, implemented according to http://wiki.msgpack.org/display/MSGPACK/Format+specification.

This Common Lisp library provides reader macros for concise expression of function partial application and composition.

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.

CL-random-forest is an implementation of Random Forest for multiclass classification and univariate regression written in Common Lisp. It also includes an implementation of Global Refinement of Random Forest.

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

This is a collection of useful helper modules and standard implementations for Radiance interfaces.

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/.
