System-Load is a Common Lisp library for accessing the system's CPU and memory usage.

This is a small library to display a native GUI message box. This can be useful to show error messages and other informational pieces should the application fail and be unable to do so using its standard UI.

Transducers are an ergonomic and extremely memory-efficient way to process a data source. Data source refers to simple collections like lists or vectors, but also potentially large files or generators of infinite data.

This library provides trivial percent encoding and decoding functions for URLs.

Support library for numcl. Registers a function as an additional form that is considered as a candidate for a constant.

CL-FAST-ECS is a Common Lisp library providing an implementation of the ECS pattern, primarily focused on speed and interactive development.

ECS is an architectural data-oriented design pattern that allows for the effective processing of a large number of in-game objects while keeping the code and data separated. This provides flexibility in the way that game objects are built at runtime.

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.

Support library for numcl. Registers a function as an additional form that is considered as a candidate for a constant.

Retrospectiff is a common lisp library for reading and writing images in the TIFF (Tagged Image File Format) format.

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 implements a basic promise datastructure, which is useful for dealing with asynchronous behaviours. Importantly, this library does not use any other libraries or frameworks, and instead leaves the execution and state transition of promise objects in your control, making it easy to integrate.

This package provides CFFI bindings to the ASSIMP library for Common Lisp.

Simple color library for Common Lisp.

The GRAPH Common Lisp library provides a data structures to represent graphs, as well as some graph manipulation and analysis algorithms (shortest path, maximum flow, minimum spanning tree, etc.).

Slite interactively runs your Common Lisp tests (currently only FiveAM and Parachute are supported). It allows you to see the summary of test failures, jump to test definitions, rerun tests with debugger all from inside Emacs.

In order to work, this also requires the slite Common Lisp system to be present. See the *cl-slite packages.

Ningle is a lightweight web application framework for Common Lisp.

FARE-MOP is a small collection of utilities using the MetaObject Protocol. It notably contains a SIMPLE-PRINT-OBJECT method, and a SIMPLE-PRINT-OBJECT-MIXIN mixin that allow you to trivially define PRINT-OBJECT methods that print the interesting slots in your objects, which is great for REPL interaction and debugging.

This is a small OS portability library to retrieve and set file attributes not supported by the Common Lisp standard functions.

This is an implementation of a Markdown parser in Common Lisp.

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

Simplified-Types is a library that provides functions for simplifying Common Lisp type specifiers. The API consists of two functions:

• simplify-type takes a type specifier and, optionally, an environment, and returns the corresponding simplified type.

• simplified-type-of takes an object and returns the simplified type of that object.

Domain specific language for producing TeX documents with Common Lisp.

This library provides payment API wrappers over BTCPay, Paypal, and Stripe.

There are plenty of Lisp Markup Languages out there - every Lisp programmer seems to write at least one during his career - and CL-WHO (where WHO means "with-html-output" for want of a better acronym) is probably just as good or bad as the next one.
