This package provides a Common Lisp implementation of Base64 encoding and decoding. Base64 encoding is a technique to encode binary data in a portable, safe printable, 7-bit ASCII format.

bubble-operator-upwards is a function that bubbles an operator upwards in a form, demultiplexing all alternative branches by way of cartesian product.

A heap-based priority queue whose first and foremost priority is speed.

This library can be used to print the licenses used by a Common Lisp project and its dependencies.

string-case is a Common Lisp macro that generates specialised decision trees to dispatch on string equality.

ADOPT is a simple UNIX-style option parser in Common Lisp, heavily influenced by Python's optparse and argparse.

The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

This is a library for access to atomic operation primitives such as compare-and-swap. It aims to be a rather thin layer over what the implementations offer.

simple-optimization is a Common Lisp library providing a function to solve unconstrained optimization problems numerically using either the gradient descent or a quasi-Newton method.

Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.

Supertrace provides a superior Common Lisp trace functionality for debugging and profiling real world applications.

This is a Common Lisp implementation of the MessagePack (http://msgpack.org/) serialization/deserialization format, implemented according to http://wiki.msgpack.org/display/MSGPACK/Format+specification.

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.

This package provides a Common Lisp system with a collection of common tests and operations to help handling pathnames. It does not actually deal in handling the accessing of files on the underlying system however.

This is a utility kit for cl-sdl2 that provides something similar to GLUT. However, it's also geared at being useful for "real" applications or games.

Defstar is a collection of Common Lisp macros that can be used in place of defun, defmethod, defgeneric, defvar, defparameter, flet, labels, let* and lambda. Each macro has the same name as the form it replaces, with a star added at the end, e.g. defun. (the exception is the let* replacement, which is called *let).

This package provides an interface to the gnuplot plotting utility. The intention of the API is to resemble to some of the plot commands of octave or matlab.

string-pokemonize provides a function that alternates uppercase and lowercase characters for a given string.

This is a Common Lisp autowrapping facility for quickly creating clean and lean bindings to C libraries.

Pileup is a portable, performant, and thread-safe binary heap for Common Lisp.

Common Lisp implementation of Graham Cormode and S. Muthukrishnan's Effective Computation of Biased Quantiles over Data Streams in ICDE’05.

This Common Lisp library contains the core classes and pixel access macros for the Opticl image processing library.

This is a Common Lisp library providing various utilities.

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