The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

PARSE is a simple token parsing library for Common Lisp.

This Common Lisp library provides a fast reader for data in LibSVM format.

Portable Threads (and Scheduled and Periodic Functions) API for Common Lisp (from GBBopen project).

CL-DATA-STRUCTURES is a Common Lisp library providing a portable collection of mutable and immutable data structures (dictionaries, sets, queues, sequences) and algorithms.

This package provides a Common Lisp system which has only one function to return the CPU count of the current system.

This is a Common Lisp library for reading PNG images.

Duologue is high-level interaction library for Common Lisp. It features coloured printing via cl-ansi-text and readline completion.

Parenscript is a translator from an extended subset of Common Lisp to JavaScript. Parenscript code can run almost identically on both the browser (as JavaScript) and server (as Common Lisp).

Parenscript code is treated the same way as Common Lisp code, making the full power of Lisp macros available for JavaScript. This provides a web development environment that is unmatched in its ability to reduce code duplication and provide advanced meta-programming facilities to web developers.

At the same time, Parenscript is different from almost all other "language X" to JavaScript translators in that it imposes almost no overhead:

• No run-time dependencies: Any piece of Parenscript code is runnable as-is. There are no JavaScript files to include.

• Native types: Parenscript works entirely with native JavaScript data types. There are no new types introduced, and object prototypes are not touched.

• Native calling convention: Any JavaScript code can be called without the need for bindings. Likewise, Parenscript can be used to make efficient, self-contained JavaScript libraries.

• Readable code: Parenscript generates concise, formatted, idiomatic JavaScript code. Identifier names are preserved. This enables seamless debugging in tools like Firebug.

• Efficiency: Parenscript introduces minimal overhead for advanced Common Lisp features. The generated code is almost as fast as hand-written JavaScript.

Common Lisp ships with a set of powerful built in data structures including the venerable list, full featured arrays, and hash-tables. CL-containers enhances and builds on these structures by adding containers that are not available in native Lisp (for example: binary search trees, red-black trees, sparse arrays and so on), and by providing a standard interface so that they are simpler to use and so that changing design decisions becomes significantly easier.

Xmls is a self-contained, easily embedded parser that recognizes a useful subset of the XML spec. It provides a simple mapping from XML to Lisp structures or s-expressions and back.

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

FXML is a secure-by-default, error-recovering XML parser and serializer. It is a fork of CXML.

You should use FXML instead of CXML if:

• You are parsing potentially ill-formed XML.

• You are parsing potentially malicious XML.

• You need to use Klacks with namespaces.

FXML’s API is very close to CXML's, and for the most part you can refer to the CXML documentation for usage.

simple-routes is a simple Common Lisp RESTful routing facility on top of Hunchentoot.

RESTAS is a Common Lisp web application framework.

CL-ANA is a data analysis library in Common Lisp providing tabular and binned data analysis along with nonlinear least squares fitting and visualization.

This package provides a grab bag of miscellaneous Common Lisp utilities.

This package provides CIEL as a precompiled binary and a full-featured REPL for the terminal.

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.

Serapeum is a conservative library of Common Lisp utilities. It is a supplement, not a competitor, to Alexandria.

CAMBL is a Common Lisp library providing a convenient facility for working with commoditized values. It does not allow compound units (and so is not suited for scientific operations) but does work rather nicely for the purpose of financial calculations.

This is a Common Lisp library to handle the IBM PC version of the IXF (Integration Exchange Format) file format.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

Defstar is a collection of Common Lisp macros that can be used in place of defun, defmethod, defgeneric, defvar, defparameter, flet, labels, let* and lambda. Each macro has the same name as the form it replaces, with a star added at the end, e.g. defun. (the exception is the let* replacement, which is called *let).
