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

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

This is a library for representing and mapping colours between their various spaces.

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

This is a small Common Lisp library to make slugs, mainly for URIs, from English and beyond.

This package provides functions for generating lorem ipsum text.

McCLIM is an implementation of the Common Lisp Interface Manager specification, a toolkit for writing GUIs in Common Lisp.

definitions-systems provides a simple unified extensible way of processing named definitions.

This is a Common Lisp library for reading PNG images.

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

This library provides a uniform API, as specified in Common Lisp the Language 2, for accessing information about variable and function bindings from implementation-defined lexical environment objects. All major Common Lisp implementations are supported, even those which don't support the CLTL2 environment access API.

This is a library for reading semi-raw user input from terminals. Semi-raw as in, we can't detect if the user pressed the Control key alone, and the function keys are a mystery. What is supported, however, is:

• Regular characters

• Control+[key]

• Alt+[key]

• Control+Alt+[key]

Collections of accessor functions and patterns to access the elements in compound type specifier, e.g. dimensions in (array element-type dimensions)

This library provides Glib, GIO and Gobject bindings for Common Lisp via Gobject Introspection.

MT19937 is a portable Mersenne Twister pseudo-random number generator for Common Lisp.

This Common Lisp library provides functions for Zstandard compression/decompression using bindings to the libzstd C library.

The purpose of this library is to provide a collection of implementations of trees.

In contrast to existing libraries such as cl-containers, it does not impose a particular use for the trees. Instead, it aims for a stratified design, allowing client code to choose between different levels of abstraction.

As a consequence of this policy, low-level interfaces are provided where the concrete representation is exposed, but also high level interfaces where the trees can be used as search trees or as trees that represent sequences of objects.

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

This package provides a recursive-descent parser DSL for Common Lisp. It's intended as a simpler alternative to parser generators.

CLML (Common Lisp Machine Learning) is a high performance and large scale statistical machine learning package

EASY-ROUTES is yet another routes handling system on top of Hunchentoot. It's just glue code for Restas routing subsystem (CL-ROUTES).

It supports:

• dispatch based on HTTP method

• arguments extraction from the url path

• decorators

• URL generation from route names

This package provides EASY-ROUTES, EASY-ROUTES+DJULA and EASY-ROUTES+ERRORS systems.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

This package provides an enhanced EVAL-WHEN macro that supports a shorthand for (eval-when (:compile-toplevel :load-toplevel :execute) ...), addressing concerns about verbosity.

This package provides a Common Lisp system CHLOROPHYLL which implements an ANSI escape code functionality.
