This library allows you to define custom indentation hints for your macros if the one recognised by SLIME automatically produces unwanted results.

VAS-STRING-METRICS provides the Jaro, Jaro-Winkler, Soerensen-Dice, Levenshtein, and normalized Levenshtein string distance/similarity metrics algorithms.

cl-mysql is a Common Lisp implementation of a MySQL wrapper.

CL-octet-streams is a library implementing in-memory octet streams for Common Lisp. It was inspired by the trivial-octet-streams and cl-plumbing libraries.

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.

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

This is a Common Lisp library providing RFC 3986 percent-encoding.

cl-alexandria-plus is a conservative set of extensions to cl-alexandria utilities.

This is a library for reading semi-raw user input from terminals. Semi-raw as in, we can't detect if the user pressed the Control key alone, and the function keys are a mystery. What is supported, however, is:

• Regular characters

• Control+[key]

• Alt+[key]

• Control+Alt+[key]

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

There are plenty of Lisp Markup Languages out there - every Lisp programmer seems to write at least one during his career - and CL-WHO (where WHO means "with-html-output" for want of a better acronym) is probably just as good or bad as the next one.

Spatial-trees is a set of dynamic index data structures for spatially-extended data.

This is a Common Lisp library providing a set of macros for generating lexical analyzers automatically. The lexers generated using cl-lex can be used with cl-yacc.

This library provides arbitrary precision (floating point) real numbers in Common Lisp.

This library provides an OS and implementation independent access to timeouts.

This library allows you to implement and enforce proper finalization of compile-time constructs while building Lisp source files.

It produces two systems: asdf-finalizers and list-of.

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

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.

cl-inotify uses cl-cffi to provide a Common Lisp interface to the Linux inotify API.

A Common Lisp library implementing a few different kinds of queues:

• Bounded and unbounded FIFO queues.

• Lossy bounded FIFO queues that drop elements when full.

• Unbounded random-order queues that use less memory than unbounded FIFO queues.

Additionally, a synchronization wrapper is provided to make any queue conforming to the jpl-queues API thread-safe for lightweight multithreading applications. (See Calispel for a more sophisticated CL multithreaded message-passing library with timeouts and alternation among several blockable channels.)

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

cl-cron is a simple tool that provides cron like facilities directly inside of Common Lisp.

This package implements an algorithm for the spelling of enharmonics and dealing with ties and dots in rhythm notation.

Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.
