File-Notify is a Common Lisp library for getting notifications for file accesses and changes.

This package provides a concise, intuitive and flexible macro for trivial lambdas that eschews explicit naming of parameter variables in favor of positional references, with support for a used or ignored &rest parameter and automatic declaration of ignored parameters when logical gaps are left in the positional references. Further convenience features are provided.

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

Periods is a Common Lisp library providing a set of utilities for manipulating times, distances between times, and both contiguous and discontiguous ranges of time.

This package provides a library for parsing MIME types, in the spirit of http://code.google.com/p/mimeparse/, with a Common Lisp flavor.

This is a small library to display a native GUI message box. This can be useful to show error messages and other informational pieces should the application fail and be unable to do so using its standard UI.

MOP utilities provide a common interface between Lisps and make the MOP easier to use.

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

Retrospectiff is a common lisp library for reading and writing images in the TIFF (Tagged Image File Format) format.

CLAWK is an AWK implementation embedded into Common Lisp.

For is a library for an extensible iteration macro. It allows you to write concise looping constructs similar to loop and iterate. Unlike loop however it is extensible and sensible, and unlike iterate it does not require code-walking and is easier to extend.

This is a keymap facility for Common Lisp inspired by Emacsy (keymap.scm) which is inspired by Emacs.

• Support prefix keys to other keymaps. For instance, if you prefix my-mode-map with C-c, then all bindings for my-mode will be accessible after pressing C-c.

• List all bindings matching a given prefix. (Also known as which-key in Emacs.)

• List the bindings associated to a command.

• Support multiple inheritance.

• Support keycode.

• Validate keyspec at compile time.

• define-key can set multiple bindings in a single call.

• Support multiple scheme to make it easy to switch between, say, Emacs-style and VI-style bindings. This orthogonality to keymaps composes better than having multiple keymaps: changing scheme applies to the entire program, which is easier than looping through all keymaps to change them.

• Translate keyspecs as a fallback. For instance if shift-a is not bound, check A.

• Behaviour can be customized with global parameters such as *print-shortcut*.

• The compose function can merge multiple keymaps together.

• Support multiple arguments when that makes sense (e.g. multiple keymaps for lookup-key).

• Key remapping à-la Emacs.

• Typed keymaps, i.e. keymaps where bound values can only be of a given type. This is convenient to catch typos, for instance when binding 'FOO instead of #'FOO.

This package ensures that special subclasses of standard-object cluster right in front of standard-object in the class precedence list.

This library provides Glib, GIO and Gobject bindings for Common Lisp via Gobject Introspection.

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

The canonical way to determine the size of a file in bytes, using Common Lisp, is to open the file with an element type of (unsigned-byte 8) and then calculate the length of the stream. This is less than ideal. In most cases it is better to get the size of the file from its metadata, using a system call.

This library exports a single function, file-size-in-octets. It returns the size of a file in bytes, using system calls when possible.

This package contains the specification of all functions and variables from GLSL as data.

A collection of Common Lisp utility functions and macros mostly not found in other utility packages.

NJSON aims to make it convenient for one to decode, encode, and process JSON data, in the minimum keystrokes/minutes possible.

NJSON is parser-independent, with existing Common Lisp JSON parsers being loadable as additional system. jzon is included by default, though. Conveniences that NJSON provides are:

• encode and decode as single entry points for JSON reading and writing, be it from streams/string/files, or from those.

• jget, jcopy, jkeys, and their aliases to manipulate the decoded objects' properties without the need to worry about the low-level details of how these values are decoded.

• jif, jwhen, jor, jand, and other macros mimicking Lisp ones, while using truth values of JSON-decoded data.

• jbind and jmatch macros to destructure and validate parsed JSON.

• njson/aliases package to nickname to j for all the forms conveniently accessible as j:get, j:copy, j:if etc.

This library is a fork of SSL-CMUCL. The original SSL-CMUCL source code was written by Eric Marsden and includes contributions by Jochen Schmidt. Development into CL+SSL was done by David Lichteblau.

cl-incless implements print-object methods for many standard classes.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.

This package provides a macro that allows foreign functions to access the contents of the array at a given pointer, using the best available method given the Common Lisp implementation.

This package provides functions for base32 encoding and decoding as defined in RFC4648.
