BOOST-LEXER is a tokenizer for Common Lisp that makes heavy use of BOOST-RE.

Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack.

Colony provides a system and workflow that helps describe the elements needed to write 2D or 3D games. It was designed with several domain specific languages that make it easier to describe, manipulate, and use assets commonly found in game making. Such assets include (but are not limited to) textures, materials, shader programs, and scene trees of actors that are available for instantiation. Colony Engine also knows how to accept input from keyboards and most joysticks and gamepads.

The component system is a hybrid model between an ECS and an object model. The components are defined similar to CLOS defclass, and regular generic methods can be used with them. Components are added to Actors which represent game concepts like players, scenery, effects, etc. We define a component protocol invoked by Colony Engine to move your components to the next state and render them each frame.

This is a Common Lisp implementation of the Encoding for Robust Immutable Storage specification (ERIS).

Eclector is a portable Common Lisp reader that is highly customizable, can recover from errors and can return concrete syntax trees.

In contrast to many other reader implementations, eclector can recover from most errors in the input supplied to it and continue reading. This capability is realized as a restart.

It can also produce instances of the concrete syntax tree classes provided by the concrete syntax tree library.

Common Lisp library for channel-based concurrency. In a nutshell, you create various threads sequentially executing tasks you need done, and use channel objects to communicate and synchronize the state of these threads.

This package provides the Common Lisp part of the emacs-slite test runner.

with-user-abort is a Common Lisp portability library providing a like-named macro that catches the SIGINT signal.

The Common Foreign Function Interface (CFFI) purports to be a portable foreign function interface for Common Lisp. The CFFI library is composed of a Lisp-implementation-specific backend in the CFFI-SYS package, and a portable frontend in the CFFI package.

NJSON aims to make it convenient for one to decode, encode, and process JSON data, in the minimum keystrokes/minutes possible.

NJSON is parser-independent, with existing Common Lisp JSON parsers being loadable as additional system. jzon is included by default, though. Conveniences that NJSON provides are:

• encode and decode as single entry points for JSON reading and writing, be it from streams/string/files, or from those.

• jget, jcopy, jkeys, and their aliases to manipulate the decoded objects' properties without the need to worry about the low-level details of how these values are decoded.

• jif, jwhen, jor, jand, and other macros mimicking Lisp ones, while using truth values of JSON-decoded data.

• jbind and jmatch macros to destructure and validate parsed JSON.

• njson/aliases package to nickname to j for all the forms conveniently accessible as j:get, j:copy, j:if etc.

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

Additional dolist style macros for Common Lisp, such as doalist, dohash, dolist*, doplist, doseq and doseq*.

Zippy is a library for the PKWARE Zip archive format. It can read and write zip files. It features:

• archive inspection without extraction;

• Zip64 support;

• split archive support;

• PKWARE decryption;

• fast deflate decompression thanks to 3bz;

• operates on streams and vectors;

• can compress stream->stream;

• extensible for other encryption and compression mechanisms.

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.

Periods is a Common Lisp library providing a set of utilities for manipulating times, distances between times, and both contiguous and discontiguous ranges of time.

This Common Lisp library contains various handy utilities to help autowrapping with claw.

Just wrap your Common Lisp function in this macro call and it will be optimized for tail recursion. You will be warned if the function is not tail recursive.

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.

MT19937 is a portable Mersenne Twister pseudo-random number generator for Common Lisp.

This is a Common Lisp macro for defining temporary caches that invalidate based on expressions evaluating to different values.

Common Lisp comes with quite some functions to compare objects for equality, yet none is applicable in every situation and in general this is hard, as equality of objects depends on the semantics of operations on them. As consequence, users find themselves regularly in a situation where they have to roll their own specialized equality test.

This module provides one of many possible equivalence relations between standard Common Lisp objects. However, it can be extended for new objects through a simple CLOS protocol. The rules when two objects are considered equivalent distinguish between mutating and frozen objects. A frozen object is promised not to be mutated in the future in a way that operations on it can notice the difference.

We have chosen to compare mutating objects only for identity (pointer equality), to avoid various problems. Equivalence for frozen objects on the other hand is established by recursing on the objects' constituent parts and checking their equivalence. Hence, two objects are equivalent under the OBJECT= relation, if they are either identical, or if they are frozen and structurally equivalent, i.e. their constituents are point-wise equivalent.

Since many objects are potentially mutable, but are not necessarily mutated from a certain point in their life time on, it is possible to promise to the equivalence relation that they remain frozen for the rest of their life time, thus enabling coarser equivalence than the often too fine-grained pointer equality.

This is a portability library that allows one to fully override the standard debugger provided by their Common Lisp system for situations where binding *debugger-hook* is not enough -- most notably, for break.

GARBAGE-POOLS is Common Lisp re-implementation of the APR Pools for resource management.
