fare-utils is a small collection of utilities. It contains a lot of basic everyday functions and macros.

This is a Common Lisp package for hash table creation with flexible, extensible initializers.

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

This is a backend for the linear-programming Common Lisp library using the GNU Linear Programming Kit (GLPK) library.

Magic (ed) is a tiny editing facility for Common Lisp, where you can directly load, edit, manipulate and evaluate file or file content from REPL. This package also can be a starting point for people who are not accustomed to Emacs or SLIME and would like to continue using their default terminal/console editor with Common Lisp.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

Clamp is an attempt to bring the powerful, but verbose, language of Common Lisp up to the terseness of Arc.

There are two parts to Clamp. There is the core of Clamp, which implements the utilities of Arc that are easily converted from Arc to Common Lisp. The other part is the "experimental" part. It contains features of Arc that are not so easy to copy (ssyntax, argument destructuring, etc.).

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 a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

This package provides a Common Lisp bindings to glfw, an OpenGL application development library.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

jsown is a high performance Common Lisp JSON parser. Its aim is to allow for the fast parsing of JSON objects in Common Lisp. Recently, functions and macros have been added to ease the burden of writing and editing jsown objects.

jsown allows you to parse JSON objects quickly to a modifiable Lisp list and write them back. If you only need partial retrieval of objects, jsown allows you to select the keys which you would like to see parsed. jsown also has a JSON writer and some helper methods to alter the JSON objects themselves.

A dataflow extension to Common Lisp that maintains a consistent state of cells according to functions specifying their relation.

Prometheus.io Common Lisp client.

This package provides CFFI bindings to convert between different character encodings using iconv.

This Common Lisp library provides function to make QR codes and to save them as PNG files.

with-user-abort is a Common Lisp portability library providing a like-named macro that catches the SIGINT signal.

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

Zippy is a library for the PKWARE Zip archive format. It can read and write zip files. It features:

• archive inspection without extraction;

• Zip64 support;

• split archive support;

• PKWARE decryption;

• fast deflate decompression thanks to 3bz;

• operates on streams and vectors;

• can compress stream->stream;

• extensible for other encryption and compression mechanisms.

Unifies a parametrized type specifier against an actual type specifier. Importantly, it handles complicated array-subtypes and number-related types correctly.

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

Schemeish implements several useful Scheme constructs for Common Lisp. These include named-let, define, scheme argument lists, and a shortcut to FUNCALL with [] instead of ().

This is a small Common Lisp library that finds an open port within a range.
