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 is a Common Lisp library providing a unified way to work with package locks across supported Common Lisp implementations.

This package provides a framework to unify arbitrary Common Lisp objects while constructing bindings for placeholders (unification variables) in a template sublanguage.

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

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.

Parse INI formatted files into a Common Lisp list structure.

This package provide a Common Lisp library for .zip-file reading and writing.

Library to fuzzily parse time and date strings into a universal-time timestamp.

The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

This library contains utilities for parsing Common Lisp code.

This package provides a Common Lisp library to work with the JSON file format.

This library introduces fast generic functions, i.e. functions that behave just like regular generic functions, except that the can be sealed on certain domains. If the compiler can then statically detect that the arguments to a fast generic function fall within such a domain, it will perform a variety of optimizations.

This collection of utilities is useful in contexts where you want a macro that uses lambda-lists in some fashion but need more precise processing.

3bz is an implementation of Deflate decompression (RFC 1951) optionally with zlib (RFC 1950) or gzip (RFC 1952) wrappers, with support for reading from foreign pointers (for use with mmap and similar, etc), and from CL octet vectors and streams.

XSubseq provides functions to be able to handle "subseq"s more effieiently.

This library provides the FORMGREP function and related utilities which find top-level Lisp forms matching the regular expression corresponding to an operator name, returning the matched forms and the names of the files and the line numbers where they were found.

This library provides all of

• ad hoc polymorphism and

• subtype polymorphism

• parametric polymorphism (in a very limited sense)

to dispatch on the basis of types rather than classes.

The GNU Scientific Library for Lisp (GSLL) allows the use of the GNU Scientific Library (GSL) from Common Lisp. This library provides a full range of common mathematical operations useful to scientific and engineering applications. The design of the GSLL interface is such that access to most of the GSL library is possible in a Lisp-natural way; the intent is that the user not be hampered by the restrictions of the C language in which GSL has been written. GSLL thus provides interactive use of GSL for getting quick answers, even for someone not intending to program in Lisp.

Alloy is a user interface toolkit. It is defined through a set of protocols that allow for a clear interface, as well as a standardised way to integrate Alloy into a target backend.

This package provides Common Lisp bindings for libev.

FLARE is a library designed to allow quick and precise particle effect creations. It does not concern itself with displaying and only with the management and movement of particles. As such, it can easily be integrated into any existing or future application.

This package provides an automatic generator for ASDF's .asd files.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.

This library contains generic hacks meant to be used in any project. It was originally developed for the Cells library.
