FLOW is a flowchart graph library. Unlike other graphing libraries, this one focuses on nodes in a graph having distinct ports through which connections to other nodes are formed. This helps in many concrete scenarios where it is important to distinguish not only which nodes are connected, but also how they are connected to each other.

Particularly, a lot of data flow and exchange problems can be reduced to such a flowchart. For example, an audio processing library may present its pipeline as a flowchart of segments that communicate with each other through audio sample buffers. Flow gives a convenient view onto this kind of problem, and even allows the generic visualisation of graphs in this format.

This library can be used to display a progress bar on one line.

This package provides a priority queue implemented with an array-based heap.

This package provides a Common Lisp library for dice rolling and working with dice-roll statistics.

LMDB, the Lightning Memory-mapped Database, is an ACID key-value database with multiversion concurrency control. This package is a Common Lisp wrapper around the C LMDB library. It covers most of C LMDB's functionality, has a simplified API, much needed safety checks, and comprehensive documentation.

DATA-SIFT is a Common Lisp data validation and transformation library inspired by cl-data-format-validation and WTForms validators.

This library contains code that implements Common Lisp hash tables.

cl-annot is an general annotation library for Common Lisp.

This package provides a portability layer for the extensible sequences standard extension to Common Lisp. Extensible sequences allow you to create your own sequence types that integrate with the rest of the functions and operations that interact with sequences.

A modern and consistent Common Lisp string manipulation library that focuses on modernity, simplicity and discoverability: (str:trim s) instead of (string-trim '(#\Space ...) s)), or str:concat strings instead of an unusual format construct; one discoverable library instead of many; consistency and composability, where s is always the last argument, which makes it easier to feed pipes and arrows.

The GTWIWTG library (Generators The Way I Want Them Generated -- technically not generators, but iterators) is meant to be small, explorable, and understandable.

This is a Common Lisp library providing various utilities.

This package contains a Gemini client library for Common Lisp. A subsystem offers an experimental GUI Gemini client.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

This is a library to provide cross-platform access to gamepads, joysticks, and other such HID devices.

This package allows flexible specification of package-local preferences.

GECO (Genetic Evolution through Combination of Objects) is an extensible, object-oriented framework for prototyping genetic algorithms in Common Lisp.

CLACHE provides a general caching facility for Common Lisp. The API is similar to the standard hash-table interface.

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

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.

string-pokemonize provides a function that alternates uppercase and lowercase characters for a given string.

This is a collection of useful helper modules and standard implementations for Radiance interfaces.

This Common Lisp package provides a regular expression engine.

This is a Common lisp library to unify access to the most common dictionary-like data structures.
