core-gp is a Common Lisp library for genetic programming (GP) algorithms. It allows standard GP, strongly-typed GP, grammatical evolution as well as standard genetic algorithms.

This library implements the let+ macro, which is a dectructuring extension of let*. It features:

• Clean, consistent syntax and small implementation (less than 300 LOC, not counting tests)

• Placeholder macros allow editor hints and syntax highlighting

• &ign for ignored values (in forms where that makes sense)

• Very easy to extend

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.

This library extracts the TLD (Top Level Domain) from domains. The information is taken from https://publicsuffix.org.

A utility for running external programs, built on UIOP. Cmd is designed to be natural to use, protect against shell interpolation and be usable from multi-threaded programs.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

This package provides supports for unicode normalization, RFC8264 and RFC7564.

This package provides first-class global environments for Common Lisp.

This library provides the FORMGREP function and related utilities which find top-level Lisp forms matching the regular expression corresponding to an operator name, returning the matched forms and the names of the files and the line numbers where they were found.

CL-UNICODE is a portable Unicode library Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

This is a Common Lisp library to enable simple message pipelines.

cl-tar is a Common Lisp library providing a high-level interface for interacting with tar archives.

Wu-Decimal enables convenient, arbitrary-precision decimal arithmetic through a reader macro, #$, and an update to the pprint dispatch table. Wu-Decimal uses the CL rational type to store decimals, which enables numeric functions such as +, -, etc., to operate on decimal numbers in a natural way.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

cl-syslog is a Common Lisp library that provides access to the syslog logging facility.

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

one-more-re-nightmare is a regular expression engine that uses the technique presented in Regular-expression derivatives re-examined (Owens, Reppy and Turon, 2009; doi:10.1017/S0956796808007090) to interpret and compile regular expressions.

Dexador is yet another HTTP client for Common Lisp with neat APIs and connection-pooling. It is meant to supersede Drakma.

This package provides a KDL reader/writer for Common Lisp.

This package provides a Common Lisp bindings to glfw, an OpenGL application development library.

A library for encoding text in various web-savvy encodings.

This is a Common Lisp library that publishes D-Bus objects as well as send and notify other objects connected to a bus.

This is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

A common lisp library that provides extensible function result caching based on arguments (an expanded form of memoization).
