This package provides a way of extracting and replicating the compile-time side-effects of forms.

This library provides modern file handling for Common Lisp, which avoids many of the pitfalls of pathnames.

This Common Lisp library provides function to make QR codes and to save them as PNG files.

cl-template is a template engine for Common Lisp, taking inspiration from Ruby's ERb module.

This package exports the following function to parse floating-point values from a string in Common Lisp.

A miniature toolkit that contains some useful shifting/popping/pushing functions for arrays and vectors. Originally from Plump.

This Common Lisp library contains the core classes and pixel access macros for the Opticl image processing library.

string-case is a Common Lisp macro that generates specialised decision trees to dispatch on string equality.

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

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

Fully auto-generated Common Lisp bindings to Raylib (5.5/5.0) and Raygui (4.0) using claw and cffi-object.

cl-cffi-gtk is a Lisp binding to GTK+ 3 (GIMP Toolkit) which is a library for creating graphical user interfaces.

This is a Common Lisp implementation for the Mustache template system. More details on the standard are available at https://mustache.github.io.

Utility library for handling bit vectors, bit vector arithmetic, and universal integer type conversions between bit-vectors, byte-vectors, octals, decimals, and hexadecimal notation.

cl-trivial-irc is a an IRC client library with simple facilities for receiving, handling and sending messages, and without facilities for CTCP.

Often times we need to destructure a form definition in a Common Lisp macro. This library provides a set of simple utilities to help with that.

Cl-reexport makes a package reexport symbols which are external symbols in other Common Lisp packages. This functionality is intended to be used with (virtual) hierarchical packages.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

SHOULD-TEST is a methodology-agnostic and non-opinionated Common Lisp test framework, i.e. it doesn't care what kind of test approach you'd like to take.

Hunchenissr works together with issr.js for the development of interactive (changing without page refreshes) websites making use of websocket and Common Lisp server HTML generation instead of mountains of convoluted Javascript.

This is only useful if you want to start a Swank server in a Lisp processes that doesn't run under Emacs. Lisp processes created by M-x slime automatically start the server.

This is a system for two dimensional computational geometry for Common Lisp.

Note: the system assumes exact rational arithmetic, so no floating point coordinates are allowed. This is not checked when creating geometric objects.

Simply emit XML, with some complexity for handling indentation. It can be used to produce all sorts of useful XML output; it has an RSS 2.0 emitter built in, so you can make RSS feeds trivially.
