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.

Provides a simple way of directing output to a stream according to the concise and intuitive semantics of FORMAT's stream argument.

The variates package provides portable random number generation as well as numerous distributions.

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 wrapper for the SDL2_TTF library used for loading fonts and creating text assets. The library, in it's current state, can load TTF and OTF fonts and render fonts with the three different rendering modes provided by the C library (solid, shaded, and blended). While Latin text, UTF8, UNICODE, and Glyph text rendering is available only Latin text has been tested (as shown in the examples).

A hook, in the present context, is a certain kind of extension point in a program that allows interleaving the execution of arbitrary code with the execution of a the program without introducing any coupling between the two. Hooks are used extensively in the extensible editor Emacs.

In the Common LISP Object System (CLOS), a similar kind of extensibility is possible using the flexible multi-method dispatch mechanism. It may even seem that the concept of hooks does not provide any benefits over the possibilities of CLOS. However, there are some differences:

• There can be only one method for each combination of specializers and qualifiers. As a result this kind of extension point cannot be used by multiple extensions independently.

• Removing code previously attached via a :before, :after or :around method can be cumbersome.

• There could be other or even multiple extension points besides :before and :after in a single method.

• Attaching codes to individual objects using eql specializers can be cumbersome.

• Introspection of code attached a particular extension point is cumbersome since this requires enumerating and inspecting the methods of a generic function.

This library tries to complement some of these weaknesses of method-based extension-points via the concept of hooks.

Common Lisp port of Universal Tween Engine.

Quicksearch is a search-engine-interface for Common Lisp. The goal of Quicksearch is to find the Common Lisp library quickly. For example, if you will find the library about json, just type (qs:? 'json) at REPL.

The function quicksearch searches for Common Lisp projects in Quicklisp, Cliki, GitHub and BitBucket, then outputs results in REPL. The function ? is abbreviation wrapper for quicksearch.

UCONS is a Common Lisp library providing unique conses. Unique conses are different from regular conses in that, in addition to their car and cdr, they maintain a table of past users. Also, the cdr of each ucons is restricted to other uconses or nil. Uconses are meant for those situations where even reusing regular conses (to avoid consing) is too computationally expensive.

This library provides a tiny Common Lisp wrapper around setlocale(3) and can be used in conjunction with other FFI wrappers like cl-charms.

Simple and fast marshalling of Lisp datastructures. Convert any object into a string representation, put it on a stream an revive it from there. Only minimal changes required to make your CLOS objects serializable.

The cl-sqlite package is an interface to the SQLite embedded relational database engine.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

This library provides a WebSocket server and client implementation for Common Lisp.

cl-syslog is a Common Lisp library that provides access to the syslog logging facility.

Scrape on-line documentation out of a running Lisp image.

A Common Lisp library for generating a human-readable diff of two HTML documents.

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).

CLX is an X11 client library for Common Lisp. The code was originally taken from a CMUCL distribution, was modified somewhat in order to make it compile and run under SBCL, then a selection of patches were added from other CLXes around the net.

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.

Coleslaw is a static site generator written in Common Lisp.

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

Charje.documentation can used to parse Common Lisp docstrings the charje way, or it can be used to create custom docstring parsers. Docstring parsers are composed using mixin classes and initialization methods.
