simple-neural-network is a Common Lisp library for creating, training and using basic neural networks. The networks created by this library are feedforward neural networks trained using backpropagation.

atomichron is a Common Lisp library which implements a time meter which tracks how many times a form is evaluated, and how long evaluation takes. It uses atomic instructions so that meters will present correct results in the presence of multiple threads, while trying to minimize synchronization latency.

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.

This is a bindings and wrapper library to libmpg123 allowing for convenient, extensive, and fast decoding of MPEG1/2/3 (most prominently mp3) files.

This Common Lisp library converts strings, symbols and keywords between any of the following typographical cases: PascalCase, camelCase, snake_case, kebab-case (lisp-case).

This is a small library providing the ISO-639 language code to language name mapping.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

This package provides Common Lisp support for reading the Terragen .TER format. The format specification can be found at https://planetside.co.uk/wiki/index.php?title=Terragen_.TER_Format

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.

Trucler defines a CLOS-based protocol to be used by Common Lisp compilers for environment query and update. In addition, library authors can use the trucler-native interface to inspect native environments. Trucler supports introspection for variables, functions, tags, blocks and optimization policies.

Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack.

cl-jpl-util is a collection of Common Lisp utility functions and macros, primarily for software projects written in CL by the author.

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

ASDF-FLV provides support for file-local variables through ASDF. A file-local variable behaves like *PACKAGE* and *READTABLE* with respect to LOAD and COMPILE-FILE: a new dynamic binding is created before processing the file, so that any modification to the variable becomes essentially file-local.

In order to make one or several variables file-local, use the macros SET-FILE-LOCAL-VARIABLE(S).

Manual translation from C to Common Lisp of some random number generation functions from the GSL library.

qbase64 provides a fast and flexible base64 encoder and decoder for Common Lisp.

This is a Common Lisp library to extract EXIF information from image files.

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.

Eazy-Gnuplot is a Common Lisp interface to gnuplot which eschews CFFI, CLOS and structures. It communicates with gnuplot via *standard-output*, and users can plot data by printing to that stream.

A Common Lisp library for generating a human-readable diff of two HTML documents.

cl-cookie is a Common Lisp library featuring parsing of cookie headers, cookie creation, cookie jar creation and more.

This library allows you to implement and enforce proper finalization of compile-time constructs while building Lisp source files.

It produces two systems: asdf-finalizers and list-of.

This package provides simple format directives to print in colors.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.
