UBIQUITOUS is a very easy-to-use library for persistent configuration storage. It automatically takes care of finding a suitable place to save your data, and provides simple functions to access and modify the data within.

This library implements various functions to access status information about the machine, process, etc.

This package provides a simple yet powerful value inheritance scheme.

HARMONY is a library that provides you with audio processing tools as well as an audio server to play back music, sfx, and so forth. It is most suited for use in a game engine, but may feasibly also be used for more advanced things such as a DAW

Very basic library for dealing with CL's hash tables. The idea was spawned through working with enough JSON APIs and config files, causing a lot of headaches in the process.

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 library exports three symbols: with-raw-io, read-char, and read-line, to provide raw POSIX I/O in Common Lisp.

This package provides a Common Lisp templating system based on Python Django with a syntax similar to Python Jinja2.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

This package provides CFFI bindings to the Graphviz library in Common Lisp.

This library provides a modern project skeleton generator. In contract with other generators, CL-Project generates one package per file and encourages unit testing by generating a system for unit testing, so you can begin writing unit tests as soon as the project is generated.

When dealing with network protocols and file formats, it's common to have to read or write 16-, 32-, or 64-bit datatypes in signed or unsigned flavors. Common Lisp sort of supports this by specifying :element-type for streams, but that facility is underspecified and there's nothing similar for read/write from octet vectors. What most people wind up doing is rolling their own small facility for their particular needs and calling it a day.

This library attempts to be comprehensive and centralize such facilities. Functions to read 16-, 32-, and 64-bit quantities from octet vectors in signed or unsigned flavors are provided; these functions are also SETFable. Since it's sometimes desirable to read/write directly from streams, functions for doing so are also provided. On some implementations, reading/writing IEEE singles/doubles (i.e. single-float and double-float) will also be supported.

This is a small library to help you with managing the Common Lisp docstrings for your library.

This package provides easy access to the defining class and its options during initialization or reinitialization of its subcomponents.

Skippy is a Common Lisp library to read and write GIF image files.

This library is a bridge between Common Lisp and GObject Introspection, which enables Common Lisp programs to access the full interface of C+GObject libraries without the need of writing dedicated bindings.

SQL generator for Common Lisp.

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

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

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.

cl-amb provides an implementation of John McCarthy's ambiguous operator in portable Common Lisp.

This is ZS3, a library for working with Amazon's Simple Storage Service (S3) and CloudFront service from Common Lisp.

This is a Common Lisp library which provides functionality to read/write Bit Map Font (BMF) into text, JSON and XML.

assoc-utils provides utilities for manipulating association lists in Common Lisp.
