DATA-SIFT is a Common Lisp data validation and transformation library inspired by cl-data-format-validation and WTForms validators.

CLX-TrueType is pure common lisp solution for antialiased TrueType font rendering using CLX and XRender extension.

CF is a Common Lisp library for doing computations using continued fractions.

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

Utility library for handling bit vectors, bit vector arithmetic, and universal integer type conversions between bit-vectors, byte-vectors, octals, decimals, and hexadecimal notation.

This Common Lisp library provides a simple FIFO implementation with no external dependencies.

Arrow-macros provides clojure-like arrow macros (ex. ->, ->>) and diamond wands in swiss-arrows.

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

Inquisitor is a cross-implementation library providing encoding/end-of-line detection and external-format abstraction for Common Lisp.

charje.lambda-list can parse every kind of lambda list defined in the ANSI Common Lisp standard. Parsing yields only one object that has all the parsed parts of the lambda list inside. New kinds of lambda lists can be made too.

Retrospectiff is a common lisp library for reading and writing images in the TIFF (Tagged Image File Format) format.

This is an optimized Common Lisp library of Bob Jenkins' ISAAC-32 and ISAAC-64 algorithms, which are fast cryptographic random number generators: Indirection, Shift, Accumulate, Add, and Count.

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.

MAP-BIND is a macro that allows visual grouping of variables with their corresponding values in calls to mapping operators when using an inline LAMBDA.

Tripod is a Common Lisp web server aiming to ease plain text, HTML, and Gopher website hosting.

cl-template is a template engine for Common Lisp, taking inspiration from Ruby's ERb module.

This package contains an implementation of RFC 2388, which is used to process form data posted with HTTP POST method using enctype "multipart/form-data".

This library provides an OS and implementation independent access to timeouts.

Circular-Streams allows you to read streams circularly by wrapping real streams. Once you reach end-of-file of a stream, its file position will be reset to 0 and you're able to read it again.

This library contains code that implements Common Lisp hash tables.

BOOST-JSON is a simple JSON parsing library for Common Lisp.

Feeder is a syndication feed library. It presents a general protocol for representation of feed items, as well as a framework to translate these objects from and to external formats. It also implements the RSS 2.0 and Atom formats within this framework.

This package provides a UTF-8 string input stream over a binary stream for Common Lisp.

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.
