Magic (ed) is a tiny editing facility for Common Lisp, where you can directly load, edit, manipulate and evaluate file or file content from REPL. This package also can be a starting point for people who are not accustomed to Emacs or SLIME and would like to continue using their default terminal/console editor with Common Lisp.

UFFI provides a universal foreign function interface (FFI) for Common Lisp.

nontrivial-gray-streams is a compatibility system for Gray streams, which is an extension to Common Lisp that makes it possible to implement Common Lisp streams using generic functions.

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

ARNESI is Common Lisp utilities library similar to ALEXANDRIA, ANAPHORA or GOLDEN-UTILS.

This package makes it possible to name classes by lists of symbols instead of symbols.

This package allows flexible specification of package-local preferences.

Dynamic-Classes helps to ease the prototyping process by bringing dynamism to class definition.

UCONS is a Common Lisp library providing unique conses. Unique conses are different from regular conses in that, in addition to their car and cdr, they maintain a table of past users. Also, the cdr of each ucons is restricted to other uconses or nil. Uconses are meant for those situations where even reusing regular conses (to avoid consing) is too computationally expensive.

Moira is a library for monitoring and, if necessary, restarting long-running threads. In principle, it is like an in-Lisp process supervisor.

This is an implementation of a Markdown parser in Common Lisp.

cl-css-lite is a library for generating CSS from an s-exp based syntax. When compiled with Parenscript loaded in the Lisp image, it also provides the same CSS generation facilities in Parenscript-generated JavaScript code.

A utility for running external programs, built on UIOP. Cmd is designed to be natural to use, protect against shell interpolation and be usable from multi-threaded programs.

Napa-FFT3 provides Discrete Fourier Transform (DFT) routines, but also buildings blocks to express common operations that involve DFTs: filtering, convolutions, etc.

cl-alexandria-plus is a conservative set of extensions to cl-alexandria utilities.

Prometheus.io Common Lisp client.

This Common Lisp library provides a tiny utility to change the size of a simple-array ensuring that the resulting array is still a simple-array.

Moira is a library for monitoring and, if necessary, restarting long-running threads. In principle, it is like an in-Lisp process supervisor.

This library enables path variables in networking routes when using Hunchenissr for Common Lisp. If a part of the path (between two slashes) starts with a question mark (?), that symbol (without question mark) will be bound to whatever value was in the same place in the URL (as a string).

Anaphora is the anaphoric macro collection from Hell: it includes many new fiends in addition to old friends like aif and awhen.

This package provides a Common Lisp library for fetching and parsing RSS feeds data via HTTP. Currently, it supports RSS versions 0.90, 0.91, and 0.92 as well as RSS version 2.

Lack is a Common Lisp library which allows web applications to be constructed of modular components. It was originally a part of Clack, however it's going to be rewritten as an individual project since Clack v2 with performance and simplicity in mind.

This package provides an ANSI CL adaptation of the SBCL mailbox utility.

This package is a simple date and time library.
