This library retrieves locale information configured on the system. This is helpful if you want to write applications and libraries that display messages in the user's native language.

This is a baseline JPEG codec written in Common Lisp. It can be used for reading and writing JPEG image files.

cl-rmath is a simple, autogenerated foreign interface for the standalone R API libRmath. There has been no effort to provide a high-level interface for the original library, instead, this library is meant to serve as a building block for such an interface.

This is a teensy library that provides some functions to determine the mime-type of a file.

Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

This package provides a standard interface to the various package lock implementations of Common Lisp.

This is a library for access to atomic operation primitives such as compare-and-swap. It aims to be a rather thin layer over what the implementations offer.

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.

This package provides an ANSI CL adaptation of the SBCL mailbox utility.

This package provides a flexible shallow/deep copy mechanism for Common Lisp.

The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

Py4CL is a bridge between Common Lisp and Python, which enables Common Lisp to interact with Python code. It uses streams to communicate with a separate python process, the approach taken by cl4py. This is different to the CFFI approach used by burgled-batteries, but has the same goal.

This library is a Common Lisp port of all the constants from the event codes header file found on Linux and FreeBSD.

Common Lisp library for channel-based concurrency. In a nutshell, you create various threads sequentially executing tasks you need done, and use channel objects to communicate and synchronize the state of these threads.

Collections of accessor functions and patterns to access the elements in compound type specifier, e.g. dimensions in (array element-type dimensions)

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

This is a purely math-related utility kit, providing functions which can be useful for games, 3D, and GL in general.

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.

This library simplifies functional programming in Common Lisp by making it easier to make new data structures with specified changes in place.

UFFI provides a universal foreign function interface (FFI) for Common Lisp.

This Common Lisp library provides macros to access foreign memory.

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.

ARNESI is Common Lisp utilities library similar to ALEXANDRIA, ANAPHORA or GOLDEN-UTILS.

The GRAPH Common Lisp library provides a data structures to represent graphs, as well as some graph manipulation and analysis algorithms (shortest path, maximum flow, minimum spanning tree, etc.).
