This library implements the base58 encoding algorithm. It's basically base64 but with a smaller alphabet (58, as in the name) that doesn't include similar looking characters, among other things. See https://github.com/bitcoin/bitcoin/blob/master/src/base58.h for a full reference.

colorize is a Lisp library for syntax highlighting supporting the following languages: Common Lisp, Emacs Lisp, Scheme, Clojure, C, C++, Java, Python, Erlang, Haskell, Objective-C, Diff, Webkit.

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

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 package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

This is a bindings library to libout123 which allows easy cross-platform audio playback.

This package provides Common Lisp bindings to the pango text layout library.

This library implements various functions to access status information about the machine, process, etc.

40ants-plantuml provides a wrapper around the PlantUML jar library.

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.

parse-number is a library of functions for parsing strings into one of the standard Common Lisp number types without using the reader. parse-number accepts an arbitrary string and attempts to parse the string into one of the standard Common Lisp number types, if possible, or else parse-number signals an error of type invalid-number.

Periods is a Common Lisp library providing a set of utilities for manipulating times, distances between times, and both contiguous and discontiguous ranges of time.

This package parses and prints dates in RFC-1123 format.

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

This a Common Lisp library to parse HTML5 documents.

This package provides a function to parse the PATH environment variable portably in Common Lisp.

This Common Lisp package offers functions for parsing and formatting decimal numbers. The package's main interface are the functions parse-decimal-number and format-decimal-number. The former is for parsing strings for decimal numbers and the latter for pretty-printing them as strings.

Skippy is a Common Lisp library to read and write GIF image files.

This package provides a Common Lisp implementation of Google Closure Templates.

This package provides a simple yet powerful value inheritance scheme.

This is a coroutine library for Common Lisp implemented using the continuations of the cl-cont library.

An implementation of the exponential backoff algorithm in Common Lisp. Inspired by the implementation found in Chromium. Read the header file to learn about each of the parameters.

The Bordeaux-FFT library provides a reasonably efficient implementation of the Fast Fourier Transform and its inverse for complex-valued inputs, in portable Common Lisp.

This package implements The MD5 Message-Digest Algorithm, as defined in RFC 1321 by R. Rivest, published April 1992.
