Dynamic-Classes helps to ease the prototyping process by bringing dynamism to class definition.

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.

Osicat is a lightweight operating system interface for Common Lisp on Unix-platforms. It is not a POSIX-style API, but rather a simple lispy accompaniment to the standard ANSI facilities.

This Common Lisp package provides a regular expression engine.

This package provides Common Lisp CFFI bindings to the Raylib game development library.

This library lets you build a metaclass which in turn lets you specify extra slot options in its classes. Options may be easily inspected and custom inheritance may be set up. The Meta-Object Protocol (MOP) is used for the implementation - through closer-mop. Some convenience function for processing slot options are also available.

Possible use case: you want to automatically set up some definitions based on some slots, but you want to have control over it right in the class definition.

Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

Funds provides portable, purely functional data structures in Common Lisp. It includes tree based implementations for Array, Hash, Queue, Stack, and Heap.

NClasses provides helper macros to help write classes, conditions, generic functions, and CLOS code in general with less boilerplate.

It's a fork of hu.dwim.defclass-star. It includes some bug fixes and extra features like type inference.

Cells is a mature, stable extension to CLOS allowing one to create classes whose instances can have slot values determined by instance-specific formulas.

This library allows macro writers to provide better feedback to macro users when errors are signaled during macroexpansion. It uses the compiler's concept of a source-form to report where the error or warning is located.

Helps writing concise CFFI-related code.

This piece of code sets up some reader macros that make it simpler to input string literals which contain backslashes and double quotes This is very useful for writing complicated docstrings and, as it turns out, writing code that contains string literals that contain code themselves.

CLX-TrueType is pure common lisp solution for antialiased TrueType font rendering using CLX and XRender extension.

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 system implements a general definitions introspection library. It gives you the ability to retrieve definitions or bindings associated with designators such as symbols, packages, and names in general. For instance, it allows you to retrieve all function, type, variable, method, etc. definitions of a symbol.

The variates package provides portable random number generation as well as numerous distributions.

This package provides a functionality augmenting Hunchentoot error pages and logs with request and session information.

This library contains an implementation of interfaces and implementations. They're sometimes called protocols in other languages. Broadly speaking, an interface is some collection of function prototypes that a valid implementation must implement.

CL-STRFTIME is a Common Lisp compiler for the strftime “language.”

MAP-BIND is a macro that allows visual grouping of variables with their corresponding values in calls to mapping operators when using an inline LAMBDA.

This is a wrapper library to allow you to interface with the Valve SteamWorks API.

This package provides a statistical computing environment for Common Lisp.

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