Antik provides a foundation for scientific and engineering computation in Common Lisp. It is designed not only to facilitate numerical computations, but to permit the use of numerical computation libraries and the interchange of data and procedures, whether foreign (non-Lisp) or Lisp libraries. It is named after the Antikythera mechanism, one of the oldest examples of a scientific computer known.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

Just wrap your Common Lisp function in this macro call and it will be optimized for tail recursion. You will be warned if the function is not tail recursive.

Unifies a parametrized type specifier against an actual type specifier. Importantly, it handles complicated array-subtypes and number-related types correctly.

Micros is a SLIME/SWANK implementation forked for use by the Lem editor.

This package contains a few utility functions from the LispWorks library that are used in software such as ContextL.

This is a simple Common Lisp library to evaluate some forms in parallel.

This is a Common Lisp library consisting of a collection of useful GPU shader functions, written with Shadow.

This is an implementation of the "Markless standard" (https://github.com/shirakumo/markless) at version 1.0. It handles the parsing of plaintext from a stream into an abstract syntax tree composed out of strings and component objects. From there the AST can be easily compiled into a target markup language like HTML.

Cl-reexport makes a package reexport symbols which are external symbols in other Common Lisp packages. This functionality is intended to be used with (virtual) hierarchical packages.

This package provides a flexible shallow/deep copy mechanism for Common Lisp.

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.

This package provides a general-purpose connection pooling library for Common Lisp.

This is a Common Lisp bindings library to libfond, a simple OpenGL text rendering engine.

This package provides CFFI binding to libmixed audio library for Common Lisp with support of other audio formats available on GNU/Linux systems:

• Alsa

• Jack

• Openmpt

• PulseAudio

• Flac (via CL-FLAC)

• Mpg123 (via CL-MPG123)

• Ogg/vorbis (via CL-VORBIS)

• Out123 (via CL-OUT123)

• WAV

SQL generator for Common Lisp.

This is a baseline JPEG codec written in Common Lisp. It can be used for reading and writing JPEG image files.

Clavier is a general purpose validation library for Common Lisp.

This library implements special functions and has a focus on high accuracy double-float calculations using the latest algorithms.

RESTAS is a Common Lisp web application framework.

This package provides prototype Common Lisp implementations of TLS, RFC5246, ASN.1, x501,509, and PKCS1,3,5,8.

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

Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

This is a Common Lisp utilities library originating from the Zombie Raptor game engine project.
