This package provides a canonical way of converting generalized booleans to booleans.

cl-cron is a simple tool that provides cron like facilities directly inside of Common Lisp.

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.

This library is a portable compatibility layer around "Common Lisp the Language, 2nd Edition" (https://www.cs.cmu.edu/Groups/AI/html/cltl/clm/node102.html) and it exports symbols from implementation-specific packages.

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 is a Common Lisp library for reading and printing MIME content. It supports automatic conversion between 7-bit, quoted-printable and base64 encodings.

Serapeum is a conservative library of Common Lisp utilities. It is a supplement, not a competitor, to Alexandria.

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

This library contains an implementation of interfaces and implementations. They're sometimes called protocols in other languages. Broadly speaking, an interface is some collection of function prototypes that a valid implementation must implement.

This is a Common Lisp library to read and write disk-based file archives such as those generated by the tar and cpio programs on Unix.

Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

This package provides CFFI bindings and interface to Allegro 5 game developing library for Common Lisp.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

Scrape on-line documentation out of a running Lisp image.

Common Lisp port of Universal Tween Engine.

This package is a Python Numpy clone implemented in pure Common Lisp.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

This is a Common Lisp wrapper for libjpeg-turbo library which provides TurboJPEG API for compressing and decompressing JPEG images.

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

This library is a portable compatibility layer around package local nicknames (PLN). This was done so there is a portability library for the PLN API not included in DEFPACKAGE.

FXML is a secure-by-default, error-recovering XML parser and serializer. It is a fork of CXML.

You should use FXML instead of CXML if:

• You are parsing potentially ill-formed XML.

• You are parsing potentially malicious XML.

• You need to use Klacks with namespaces.

FXML’s API is very close to CXML's, and for the most part you can refer to the CXML documentation for usage.

Clamp is an attempt to bring the powerful, but verbose, language of Common Lisp up to the terseness of Arc.

There are two parts to Clamp. There is the core of Clamp, which implements the utilities of Arc that are easily converted from Arc to Common Lisp. The other part is the "experimental" part. It contains features of Arc that are not so easy to copy (ssyntax, argument destructuring, etc.).

This is a trivial utility for distinguishing between a process running in a real terminal window and a process running in a dumb one, e.g. emacs-slime.

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.
