This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

RTG-MATH provides a selection of the math routines most commonly needed for making realtime graphics in Lisp.

OpenAPI client system generator.

Loop has a consistent interface unlike other looping abstractions and ANSI list operations. You can define your own efters and gatherers that integrate tightly into other operations. All operations are non-consing when possible.

This is a Common Lisp library providing lambda shorthand macros aiming to be used in cases where the word lambda and the arguments are longer than the body of the lambda.

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

core-gp is a Common Lisp library for genetic programming (GP) algorithms. It allows standard GP, strongly-typed GP, grammatical evolution as well as standard genetic algorithms.

This package provides an implementation of the Matrix API for Common Lisp.

Parse INI formatted files into a Common Lisp list structure.

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

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.

cl-amb provides an implementation of John McCarthy's ambiguous operator in portable Common Lisp.

This package provides a Common Lisp templating system based on Python Django with a syntax similar to Python Jinja2.

STMX is a high-performance implementation of composable Transactional Memory, which is a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions, which can be composed together to make larger atomic memory transactions.

A memory transaction gets committed if it returns normally, while it gets rolled back if it signals an error (and the error is propagated to the caller).

Finally, memory transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and their effects are not visible from other threads until they commit.

Memory transactions give freedom from deadlocks, are immune to thread-safety bugs and race conditions, provide automatic roll-back on failure, and aim at resolving the tension between granularity and concurrency.

This library allows creation of hash tables with arbitrary test/hash functions, in addition to the test functions allowed by the standard (EQ, EQL, EQUAL and EQUALP), even in implementations that don't support this functionality directly.

Collections of accessor functions and patterns to access the elements in compound type specifier, e.g. dimensions in (array element-type dimensions)

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.

This is a very simple color library for Common Lisp, providing:

• Types for representing colors in HSV, HSL, and RGB spaces.

• Simple conversion functions between the above types.

• Function printing colors to HEX, RGB, RGBA, and HSL.

• Predefined colors from X11, SVG, and GDK.

This is an extension to MODULARIZE that allows your application to define interfaces in-code that serve both as a primary documentation and as compliance control.

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

A heap-based priority queue whose first and foremost priority is speed.

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 is a lisp implementation of the Open Sound Control protocol (or more accurately “data transport specification” or “encoding”). The code should be close to ANSI standard common lisp and provides self contained code for encoding and decoding of OSC data, messages, and bundles.

jzon is a correct and safe JSON RFC 8259 parser for Common Lisp.
