This is a coroutine library for Common Lisp implemented using the continuations of the cl-cont library.

Aims to be fast, modular, cachable and concise. It does so by defining each tag as a macro which expands to code printing the respective HTML source. Also employs a DSL for element attributes.

This package provides an enhanced EVAL-WHEN macro that supports a shorthand for (eval-when (:compile-toplevel :load-toplevel :execute) ...), addressing concerns about verbosity.

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 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.

Clavier is a general purpose validation library for Common Lisp.

Portable document preparation system.

This package provides a macro that allows foreign functions to access the contents of the array at a given pointer, using the best available method given the Common Lisp implementation.

This library provides GTK4 bindings for Common Lisp via Gobject Introspection, in the cl-gtk4 ASDF system.

This Common Lisp package offers functions for parsing and formatting decimal numbers. The package's main interface are the functions parse-decimal-number and format-decimal-number. The former is for parsing strings for decimal numbers and the latter for pretty-printing them as strings.

BOOST-JSON is a simple JSON parsing library for Common Lisp.

This library features a rectangle packer for sprite and texture atlases.

This is a system to help you easily and quickly deploy standalone common lisp applications as binaries. Specifically it is geared towards applications with foreign library dependencies that run some kind of GUI.

It's very basic implementation of channels and queue for Common Lisp.

This is a Common Lisp library for creating PNG images.

This Common Lisp library focuses on the small set of basic color manipulations (lightening, compliments, etc.) you might use to generate a color palette for a GUI or web page.

This library contains code that implements Common Lisp hash tables.

This library implements various functions to access status information about the machine, process, etc.

This is a (currently) brief but usable wrap for SDL2_image.

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.

parse-number is a library of functions for parsing strings into one of the standard Common Lisp number types without using the reader. parse-number accepts an arbitrary string and attempts to parse the string into one of the standard Common Lisp number types, if possible, or else parse-number signals an error of type invalid-number.

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

With static-vectors, you can create vectors allocated in static memory.

April compiles a subset of the APL programming language into Common Lisp. Leveraging Lisp's powerful macros and numeric processing faculties, it brings APL's expressive potential to bear for Lisp developers. Replace hundreds of lines of number-crunching code with a single line of APL.
