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.

Inquisitor is a cross-implementation library providing encoding/end-of-line detection and external-format abstraction for Common Lisp.

Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.

This library provides a wrapper type for secret values, to reduce the risk of accidentally revealing them.

CL-STORE is a portable serialization package which should give you the ability to store all Common Lisp data types into streams.

This Common Lisp library provides bindings for the ZeroMQ lightweight messaging kernel.

cl-change-case is a library to convert strings between camelCase, PascalCase, snake_case, param-case, CONSTANT_CASE and more.

This library is a fork of SSL-CMUCL. The original SSL-CMUCL source code was written by Eric Marsden and includes contributions by Jochen Schmidt. Development into CL+SSL was done by David Lichteblau.

cl-draw-cons-tree draws a cons tree in ASCII-art style.

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

Clop is a Common Lisp library for parsing strings in the TOML configuration file format.

This package provides a stream based JSON parser/writer, well suited as building block for higher level libraries.

BKNR.DATASTORE is an in-memory CLOS based database with transactions for Common Lisp.

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

This package provides highly optimized base64 encoding and decoding. Besides conversion to and from strings, integer conversions are supported. Encoding with Uniform Resource Identifiers is supported by using a modified encoding table that uses only URI-compatible characters.

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

Loop has a consistent interface unlike other looping abstractions and ANSI list operations. You can define your own efters and gatherers that integrate tightly into other operations. All operations are non-consing when possible.

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

This package provides a Common Lisp system which has only one function to return the CPU count of the current system.

MGL-GPR is a library of evolutionary algorithms such as Genetic Programming (evolving typed expressions from a set of operators and constants) and Differential Evolution.

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.

This package provides an ASN.1 encoder/decoder for Common Lisp.

This is a Common Lisp library for simplifying packaging and loading of compiled foreign library collection.
