This package provides CFFI bindings and interface to Allegro 5 game developing library for Common Lisp.

S-XML is a simple XML parser implemented in Common Lisp. This XML parser implementation has the following features:

• It works (handling many common XML usages).

• It is very small (the core is about 700 lines of code, including comments and whitespace).

• It has a core API that is simple, efficient and pure functional, much like that from SSAX (see also http://ssax.sourceforge.net).

• It supports different DOM models: an XSML-based one, an LXML-based one and a classic xml-element struct based one.

• It is reasonably time and space efficient (internally avoiding garbage generatation as much as possible).

• It does support CDATA.

• It should support the same character sets as your Common Lisp implementation.

• It does support XML name spaces.

This XML parser implementation has the following limitations:

• It does not support any special tags (like processing instructions).

• It is not validating, even skips DTD's all together.

This package provides a standard interface to the various package lock implementations of Common Lisp.

PAX provides an extremely poor man's Explorable Programming environment. Narrative primarily lives in so called sections that mix markdown docstrings with references to functions, variables, etc, all of which should probably have their own docstrings.

The primary focus is on making code easily explorable by using SLIME's M-. (slime-edit-definition). See how to enable some fanciness in Emacs Integration. Generating documentation from sections and all the referenced items in Markdown or HTML format is also implemented.

With the simplistic tools provided, one may accomplish similar effects as with Literate Programming, but documentation is generated from code, not vice versa and there is no support for chunking yet. Code is first, code must look pretty, documentation is code.

Staple is a documentation system. It provides you with a way to generate standalone documentation accumulated from various sources such as readmes, documentation files, and docstrings.

The canonical way to determine the size of a file in bytes, using Common Lisp, is to open the file with an element type of (unsigned-byte 8) and then calculate the length of the stream. This is less than ideal. In most cases it is better to get the size of the file from its metadata, using a system call.

This library exports a single function, file-size-in-octets. It returns the size of a file in bytes, using system calls when possible.

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).

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.

Generic documentation builder for Common Lisp projects.

This Common Lisp library implements object prevalence (see https://en.wikipedia.org/wiki/System_prevalence). It allows for (de)serializing to and from s-exps as well as XML. Serialization of arbitrary classes and cyclic data structures are supported.

This is a system implementing an advanced dialogue system that is capable of complex dialogue flow including choice trees and conditional branching. Speechless was first developed for the "Kandria" (https://kandria.com) game, and has since been separated and made public in the hopes that it may find use elsewhere or inspire other developers to build similar systems.

Speechless is based on the "Markless" (https://shirakumo.github.io/markless) document standard for its syntax and makes use of Markless' ability to be extended to add additional constructs useful for dialogue systems.

Speechless can compile dialogue from its base textual form into an efficient instruction set, which is then executed when the game is run. Execution of the dialogue is completely engine-agnostic, and only requires some simple integration with a client protocol to run.

Thanks to Markless' extensibility, Speechless can also be further extended to include additional syntax and constructs that may be useful for your particular game.

This package provides functions to encode or decode byte vectors or byte streams using the Z85 format, which is a base-85 encoding used by ZeroMQ.

dbi is a Common Lisp library providing a database independent interface for MySQL, PostgreSQL and SQLite.

This package provides a Common Lisp implementation of Base64 encoding and decoding. Base64 encoding is a technique to encode binary data in a portable, safe printable, 7-bit ASCII format.

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

This package provides the CL-SVG Common Lisp system to produce Scalable Vector Graphics files.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

This library is a collection of functions and macros for manipulating Common Lisp arrays and performing numerical calculations with them.

This is a pure Common Lisp library to create, transform and render anti-aliased vectorial paths.

This is a Common Lisp library providing logging faciltiy similar to CL-LOG and LOG4CL.

Calispel is a Common Lisp library for thread-safe message-passing channels, in the style of the occam programming language, also known as communicating sequential processes (CSP). See https://en.wikipedia.org/wiki/Communicating_sequential_processes.

Calispel channels let one thread communicate with another, facilitating unidirectional communication of any Lisp object. Channels may be unbuffered, where a sender waits for a receiver (or vice versa) before either operation can continue, or channels may be buffered with flexible policy options.

Because sending and receiving on a channel may block, either operation can time out after a specified amount of time.

A syntax for alternation is provided (like ALT in occam, or Unix select()): given a sequence of operations, any or all of which may block, alternation selects the first operation that doesn't block and executes associated code. Alternation can also time out, executing an "otherwise" clause if no operation becomes available within a set amount of time.

Calispel is a message-passing library, and as such leaves the role of threading abstractions and utilities left to be filled by complementary libraries such as Bordeaux-Threads and Eager Future.

qbase64 provides a fast and flexible base64 encoder and decoder for Common Lisp.

This package provides a safer variant of READ secure against internbombing, excessive input and macro characters.

CL-FAST-ECS is a Common Lisp library providing an implementation of the ECS pattern, primarily focused on speed and interactive development.

ECS is an architectural data-oriented design pattern that allows for the effective processing of a large number of in-game objects while keeping the code and data separated. This provides flexibility in the way that game objects are built at runtime.
