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.

RUTILS is a syntactic utilities package for Common Lisp.

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

FSet is a functional set-theoretic collections library for Common Lisp. Functional means that all update operations return a new collection rather than modifying an existing one in place. Set-theoretic means that collections may be nested arbitrarily with no additional programmer effort; for instance, sets may contain sets, maps may be keyed by sets, etc.

CL-DEBUG provides a unified way to enable or disable debug-specific code. Debugging code can be enabled or disabled relative to program features denoted by either a symbol or a keyword.

This package provides a SuperCollider client for Common Lisp.

This is a Common Lisp library to change the capitalization and spacing of a string or a symbol. It can convert to and from Lisp, english, underscore and camel-case rules.

Common Lisp port of Universal Tween Engine.

Command-Line-Args provides a main macro (command) that wraps a defun form and creates a new function that parses the command line arguments. It has support for command-line options, positional, and variadic arguments. It also generates a basic help message. The interface is meant to be easy and non-intrusive.

This package provides a client for SMTP.

This Common Lisp package contains the core math utilities of the Bodge library collection.

Datafly is a lightweight database library for Common Lisp.

This is a Common Lisp library to extract EXIF information from image files.

cl-jpl-util is a collection of Common Lisp utility functions and macros, primarily for software projects written in CL by the author.

trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

This Common Lisp library interprets escape characters the same way that most other programming language do. It provides four readtables. The default one lets you write strings like this: #"This string has a newline in it!".

cl-jpl-util is a collection of Common Lisp utility functions and macros, primarily for software projects written in CL by the author.

This Common Lisp library provides bindings for the ZeroMQ lightweight messaging kernel.

This library is part of NUMCL. It provides a macro SPECIALIZED that performs a Julia-like dispatch on the arguments, lazily compiling a type-specific version of the function from the same code. The main target of this macro is speed.

Authentic provides a light-weight and extendible solution to user/password management for Common Lisp applications. It has features such as safe password storage in a database, password reset, user confirmation tokens, and user authentication.

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

Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.
