YASON is a Common Lisp library for encoding and decoding data in the JSON interchange format.

This package provides a Common Lisp system which wraps the BORDEAUX-THREADS system to be able to run things in the main thread of the implementation, for example drawing calls of GUI applications.

This a Common Lisp library for reading and writing binary data. It is based on code from chapter 24 of the book Practical Common Lisp.

cl-template is a template engine for Common Lisp, taking inspiration from Ruby's ERb module.

This package provides an implementation of a base 16 builder for Common Lisp.

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

zsort is a collection of portable sorting algorithms. Common Lisp provides the sort and stable-sort functions but these can have different algorithms implemented according to each implementation. Also, the standard sorting functions might not be the best for a certain situations. This library aims to provide developers with more options.

This is a bindings library to libout123 which allows easy cross-platform audio playback.

This is a Common Lisp library to present tabular data in ascii-art tables.

This is a library that implements delimited continuations by transforming Common Lisp code to continuation passing style.

atomichron is a Common Lisp library which implements a time meter which tracks how many times a form is evaluated, and how long evaluation takes. It uses atomic instructions so that meters will present correct results in the presence of multiple threads, while trying to minimize synchronization latency.

This package provides a Common Lisp library for fetching and parsing RSS feeds data via HTTP. Currently, it supports RSS versions 0.90, 0.91, and 0.92 as well as RSS version 2.

This package makes it possible to name classes by lists of symbols instead of symbols.

Nodgui (No Drama GUI) is a Common Lisp binding for the Tk GUI toolkit. It also provides a few additional widgets more than the standard Tk ones.

This library lets you build a metaclass which in turn lets you specify extra slot options in its classes. Options may be easily inspected and custom inheritance may be set up. The Meta-Object Protocol (MOP) is used for the implementation - through closer-mop. Some convenience function for processing slot options are also available.

Possible use case: you want to automatically set up some definitions based on some slots, but you want to have control over it right in the class definition.

This Common Lisp library provides macros to access foreign memory.

Trivial Monitored Thread offers a very simple (aka trivial) way of spawning threads and being informed when one any of them crash and die.

Clip is an attempt at a templating library that allows you to write templates in a way that is both accessible to direct webdesign and flexible. The main idea is to incorporate transformation commands into an HTML file through tags and attributes. Clip is heavily dependent on Plump and lQuery.

DEFLATE data, defined in RFC1951, forms the core of popular compression formats such as zlib (RFC 1950) and gzip (RFC 1952). As such, Chipz also provides for decompressing data in those formats as well. BZIP2 is the format used by the popular compression tool bzip2.

This package makes it possible to name classes by lists of symbols instead of symbols.

This project is intended as a catchall for small, general-purpose extensions to Common Lisp. It contains:

• new-let, a macro that combines and generalizes let, let* and multiple-value-bind,

• gmap, an iteration macro that generalizes map.

PARSE is a simple token parsing library for Common Lisp.

Static dispatch is a Common Lisp library, inspired by inlined-generic-function, which allows standard Common Lisp generic function dispatch to be performed statically (at compile time) rather than dynamically (runtime). This is similar to what is known as "overloading" in languages such as C++ and Java.

The purpose of static dispatch is to provide an optimization in cases where the usual dynamic dispatch is too slow, and the dynamic features of generic functions, such as adding/removing methods at runtime are not required. An example of such a case is a generic equality comparison function. Currently generic functions are considered far too slow to implement generic arithmetic and comparison operations when used heavily in numeric code.

Inquisitor is a cross-implementation library providing encoding/end-of-line detection and external-format abstraction for Common Lisp.
