(X)HTMLambda is yet another (X)HTML library which emphasizes programmability and user-friendliness. Each (X)HTML element is a structured object and pretty-printing of (X)HTML trees is well defined to provide properly indented human-readable output even for complex recursive arrangements.

This is a lightweight, non-consing, optimized queue implementation for Common Lisp.

This an implementation of CDR 2: generic hash tables for Common Lisp

CL-PUNCH is a Scala-like anonymous lambda literal.

This is a collection of common cryptography functions for Common Lisp.

This is an implementation of the Unicode Standards Annex #14 (http://www.unicode.org/reports/tr14/) line breaking algorithm. It provides a fast and convenient way to determine line breaking opportunities in text.

Note that this algorithm does not support break opportunities that require morphological analysis. In order to handle such cases, please consult a system that provides this kind of capability, such as a hyphenation algorithm.

Also note that this system is completely unaware of layouting decisions. Any kind of layouting decisions, such as which breaks to pick, how to space between words, how to handle bidirectionality, and what to do in emergency situations when there are no breaks on an overfull line are left up to the user.

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).

This is a Common Lisp library to change the capitalization and spacing of a string or a symbol. It can convert to and from Lisp, english, underscore and camel-case rules.

cl-amb provides an implementation of John McCarthy's ambiguous operator in portable Common Lisp.

Germinal is a server for the Gemini protocol, written in Common Lisp.

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

This library enable rapid file search, inspection and manipulation straight from the REPL. It aims at replacing Unix tools such as find or du. It also offers a replacement to the pathname Common Lisp API. Slot writers which commit changes to disk, e.g. permissions, modification time, etc.

Alloy is a user interface toolkit. It is defined through a set of protocols that allow for a clear interface, as well as a standardised way to integrate Alloy into a target backend.

A Common Lisp client library for Apache Kafka.

CL-Ledger is a Common Lisp port of the Ledger double-entry accounting system.

The 3d-math library implements types, operators, and algorithms commonly used in math for 2D and 3D graphics. It supersedes and combines the prior libraries 3d-vectors, 3d-matrices, 3d-quaternions, and 3d-transforms. The new API is largely but not entirely backwards compatible, and adds new functionality.

This library provides a wrapper type for secret values, to reduce the risk of accidentally revealing them.

This library contains a lexer for syntaxes that use shell-like rules for quoting and commenting. It is a port of the shlex module from Python’s standard library.

Typo is a portable library for Common Lisp that does approximate reasoning about types, but without consing.

QMyND, the QITAB MySQL Native Driver, is a MySQL client library that directly talks to a MySQL server in its native network protocol.

It's a part of QITAB umbrella project.

Manual translation from C to Common Lisp of some random number generation functions from the GSL library.

assoc-utils provides utilities for manipulating association lists in Common Lisp.

Optima is a fast pattern matching library which uses optimizing techniques widely used in the functional programming world.

cl-mssql provides an interface to connect to Microsoft SQL server. It uses the libsybdb foreign library provided by the FreeTDS project.
