This is a Common Lisp wrapper for libjpeg-turbo library which provides TurboJPEG API for compressing and decompressing JPEG images.

This package provides functions to emit XML, with some complexity for handling indentation. It can be used to produce all sorts of useful XML output; it has an RSS 2.0 emitter built in, so you can make RSS feeds trivially.

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

IOlib is to be a better and more modern I/O library than the standard Common Lisp library. It contains a socket library, a DNS resolver, an I/O multiplexer(which supports select(2), epoll(4) and kqueue(2)), a pathname library and file-system utilities.

LLA is a high-level Common Lisp library built on BLAS and LAPACK, but providing a much more abstract interface with the purpose of freeing the user from low-level concerns and reducing the number of bugs in numerical code.

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

This package contains a few utility functions from the LispWorks library that are used in software such as ContextL.

MAP-BIND is a macro that allows visual grouping of variables with their corresponding values in calls to mapping operators when using an inline LAMBDA.

This is a simple extension to MODULARIZE that allows modules to define and trigger hooks, which other modules can hook on to.

Bind extends the idea of of let and destructing to provide a uniform syntax for all your accessor needs. It combines let, destructuring-bind, with-slots, with-accessors, structure editing, property or association-lists, and multiple-value-bind and a whole lot more into a single form.

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.

40ants-plantuml provides a wrapper around the PlantUML jar library.

This library allows for cooperative multitasking with help of cl-cont for continuations. It tries to mimic the API of bordeaux-threads as much as possible.

This package provides Common Lisp bindings to POSIX message queue, an IPC method that is easy to use and quick to setup.

A modern markup generation library for Common Lisp that features:

• Fast (even faster through compiling the code)

• Safety

• Support for multiple document types (markup, xml, html, html5, xhtml)

• Output with doctype

• Direct output to stream

This is a system for two dimensional computational geometry for Common Lisp.

Note: the system assumes exact rational arithmetic, so no floating point coordinates are allowed. This is not checked when creating geometric objects.

FARE-MOP is a small collection of utilities using the MetaObject Protocol. It notably contains a SIMPLE-PRINT-OBJECT method, and a SIMPLE-PRINT-OBJECT-MIXIN mixin that allow you to trivially define PRINT-OBJECT methods that print the interesting slots in your objects, which is great for REPL interaction and debugging.

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.

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

Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

This is a Common Lisp Markdown to HTML converter, using esrap for parsing, and grammar based on peg-markdown.

This is a Commin Lisp library for operating on permutations and permutation groups.

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.

cl-libxml2 is high-level Common Lisp wrapper around the libxml2 and libxslt libraries.

• Interfaces for tree manipulation (like cxml-stp).

• Interface for HTML 4.0 non-validating parsers.

• Specific APIs to process HTML trees, especially serialization.

• XPath API.

• XSLT API.

• Custom URL resolvers.

• XPath extension functions.

• XSLT extension elements.

• Translates libxml2 and libxslt errors to Lisp conditions.

• Extends the Common Lisp iterate library with custom drivers for child nodes enumeration, etc.

• The XFACTORY system provides a simple and compact syntax for XML generation.
