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 library provides all of

• ad hoc polymorphism and

• subtype polymorphism

• parametric polymorphism (in a very limited sense)

to dispatch on the basis of types rather than classes.

This package provides a way of extracting and replicating the compile-time side-effects of forms.

TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

This package provides a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

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.

Anaphora is the anaphoric macro collection from Hell: it includes many new fiends in addition to old friends like aif and awhen.

This is a library for representing and mapping colours between their various spaces.

This is a Common Lisp library that publishes D-Bus objects as well as send and notify other objects connected to a bus.

This is a small library to help you with managing the Common Lisp docstrings for your library.

This is a native Common Lisp graphics math library with an emphasis on performance and correctness.

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.

This library implements the base58 encoding algorithm. It's basically base64 but with a smaller alphabet (58, as in the name) that doesn't include similar looking characters, among other things. See https://github.com/bitcoin/bitcoin/blob/master/src/base58.h for a full reference.

Simplified-Types is a library that provides functions for simplifying Common Lisp type specifiers. The API consists of two functions:

• simplify-type takes a type specifier and, optionally, an environment, and returns the corresponding simplified type.

• simplified-type-of takes an object and returns the simplified type of that object.

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

This package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

A dataflow extension to Common Lisp that maintains a consistent state of cells according to functions specifying their relation.

This Common Lisp library provides functions for lzip (LZMA) compression/decompression using bindings to the lzlib C library.

parse-number is a library of functions for parsing strings into one of the standard Common Lisp number types without using the reader. parse-number accepts an arbitrary string and attempts to parse the string into one of the standard Common Lisp number types, if possible, or else parse-number signals an error of type invalid-number.

A Common Lisp client library for Apache Kafka.

nontrivial-gray-streams is a compatibility system for Gray streams, which is an extension to Common Lisp that makes it possible to implement Common Lisp streams using generic functions.

The cl-data-lens library provides a language for expressing data manipulations as the composition of more primitive operations.

A collection of Common Lisp utility functions and macros mostly not found in other utility packages.

This package provides the getopt function to parse command-line options. The options are organized in valid options, other arguments and unknown arguments. Optional Lisp conditions for error situations are also defined.
