jzon is a correct and safe JSON RFC 8259 parser for Common Lisp.

simple-matrix is a Common Lisp library implementing some functions to work with matrices.

This package provides support routines for the claw Common Lisp package.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

This is a Common Lisp macro for defining temporary caches that invalidate based on expressions evaluating to different values.

This package provides highly optimized base64 encoding and decoding. Besides conversion to and from strings, integer conversions are supported. Encoding with Uniform Resource Identifiers is supported by using a modified encoding table that uses only URI-compatible characters.

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.

Coalton is a dialect of ML embedded in Common Lisp. It emphasizes practicality and interoperability with Lisp, and is intended to be a DSL that allows one to gradually make their programs safer.

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

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

This a Common Lisp library to convert geographic coordinates between latitude/longitude and Open Location Code.

Slite interactively runs your Common Lisp tests (currently only FiveAM and Parachute are supported). It allows you to see the summary of test failures, jump to test definitions, rerun tests with debugger all from inside Emacs.

In order to work, this also requires the slite Common Lisp system to be present. See the *cl-slite packages.

CLAWK is an AWK implementation embedded into Common Lisp.

This is a Common Lisp library for creating PNG images.

MOP utilities provide a common interface between Lisps and make the MOP easier to use.

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.

This library allows you to define custom indentation hints for your macros if the one recognised by SLIME automatically produces unwanted results.

This is a Common Lisp library that converts floating point values to IEEE 754 binary representation.

This is a repackage of the original DejaVu Fonts with some convenience functions.

This library builds on the venerable idea of dynamically memoizing functions. A memoized function remembers results from previous computations and returns cached results when called again with the same arguments rather than repeating the computation.

This package provides an example implementation of the Common Lisp condition system and library, based on the original condition system implementation by Kent M. Pitman.

This package provides KONS-9 which can be considered as a traditional user interface driven 3D application for general artists, or as a REPL-based development environment for technical artists and software developers. These two approaches can be seamlessly combined into a flexible and powerful workflow, where non-technical users can immediately benefit from software tools and extensions developed by technical users.

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".
