This paper describes the early development stages of this project. CLoX currently consists in a port of Closette to Emacs Lisp, with some additional features, most notably, a deeper integration between types and classes and a comprehensive test suite. All these aspects are described in the paper, and we also provide a feature comparison with an alternative project called Eieio. http://www.cl-user.net/asp/libs/cl-win32ole15732Wed, 10 Mar 2010 11:29:09 GMTCommon Lisp OLE Library like Ruby's win32ole.http://www.cl-user.net/asp/libs/sheeple17026Sat, 23 Jan 2010 02:13:37 GMTSheeple is a delegative prototype-based object system inspired by CLOS. It is designed with the purpose of providing the goodies of CLOS programming, but in an object-based environment. As such, it shares a lot of syntax and semantics with CLOS, including multiple delegation (similar to multiple inheritance) and multiply-dispatched functions (similar to generic functions). http://www.cl-user.net/asp/libs/snarf.lisp17079Sun, 25 Oct 2009 12:35:45 GMTSnarf is a simple prototype-style OO language for common lisp. It uses a call syntax rather than a CLOS-style general function syntax. Snarf is so small that the entire language (about 400 lines) is in one file, plus a description of how to use the code at the end. It's been around since about 2003.http://www.cl-user.net/asp/web-sites/VisitorPattern16833Tue, 28 Apr 2009 08:07:14 GMTA software design pattern is a three-part rule which expresses a relation between a certain context, a problem, and a solution. The well-known "GoF Book" describes 23 software design patterns. Its influence in the software engineering community has been dramatic. However, Peter Norvig notes that "16 of [these] 23 patterns are either invisible or simpler [...]" in Dylan or Lisp (Design Patterns in Dynamic Programming, Object World, 1996). We claim that this is not a consequence of the notion of "pattern" itself, but rather of the way patterns are generally described; the GoF book being typical in this matter. Whereas patterns are supposed to be general and abstract, the GoF book is actually very much oriented towards mainstream object languages such as C++. As a result, most of its 23 "design patterns" are actually closer to "programming patterns", or "idioms", if you choose to adopt the terminology of the POSA Book. In this talk, we would like to envision software design patterns from the point of view of dynamic languages and specifically from the angle of CLOS, the Common Lisp Object System. Taking the Visitor pattern as an illustration, we will show how a generally useful pattern can be blurred into the language, sometimes to the point of complete disappearance. The lesson to be learned is that software design patterns should be used with care, and in particular, will never replace an in-depth knowledge of your preferred language (in our case, the mastering of first-class and generic functions, lexical closures and meta-object protocol). By using patterns blindly, your risk missing the obvious and most of the time simpler solution: the "Just Do It" pattern. http://www.cl-user.net/asp/libs/cl-famix16347Tue, 08 Jul 2008 11:22:58 GMTCL-Famix is a model extractor, that extract FAMIX-Lisp complaint models from Lisp systems.http://www.cl-user.net/asp/libs/Objective-CL15956Sun, 23 Mar 2008 13:05:52 GMTObjective-CL is a free CL/Objective-C bridge that is portable not only across Lisp implementations but also across operating systems.

This document extends that specification by defining a metaobject protocol for CLOS - that is, a description of CLOS itself as an extensible CLOS program. In this description, the fundamental elements of CLOS programs (classes, slot definitions, generic functions, methods, specializers and method combinations) are represented by first-class objects. The behavior of CLOS is provided by these objects, or, more precisely, by methods specialized to the classes of these objects. Because these objects represent pieces of CLOS programs, and because their behavior provides the behavior of the CLOS language itself, they are considered meta-level objects or metaobjects. The protocol followed by the metaobjects to provide the behavior of CLOS is called the CLOS Metaobject Protocol (MOP).http://www.cl-user.net/asp/libs/defclass-star14469Sun, 15 Oct 2006 17:24:51 GMTdefclass* and defcondition* that automatically generates accessors other things that are schematic for most defclass declarations.http://www.cl-user.net/asp/libs/span-nli14266Thu, 07 Sep 2006 07:35:36 GMTA set of portable extensions for bindings, CLOS-compatible message passing, easier manipulation of functions, continuations and cooperative multitasking.http://www.cl-user.net/asp/libs/rucksack13971Thu, 20 Jul 2006 12:11:47 GMTA portable object persistency library with support for persistent basic Lisp data types, parallel transactions, schema evolution, and more.http://www.cl-user.net/asp/libs/metacopy13755Sun, 28 May 2006 10:44:47 GMTA toolkit for specifying how to make copies of CLOS objects.http://www.cl-user.net/asp/libs/clorb13471Sat, 20 May 2006 13:04:02 GMTAn implementation of the OMG CORBA 2 specification for distributed computing, with the goal of supporting CORBA 2.6 and comply with the Lisp mappings defined by OMG.

It provides means to associate partial class and method definitions with layers and to activate and deactivate such layers in the control flow of a running program. When a layer is activated, the partial definitions become part of the program until this layer is deactivated. This has the effect that the behavior of a program can be modified according to the context of its use without the need to mention such context dependencies in the affected base program. We illustrate these ideas by providing different UI views on the same object while, at the same time, keeping the conceptual simplicity of object-oriented programming that objects know by themselves how to behave, in our case how to display themselves. These seemingly contradictory goals can be achieved by separating class definitions into distinct layers instead of factoring out the display code into different classes.http://www.cl-user.net/asp/libs/cl-prevalence12673Sat, 11 Feb 2006 19:04:30 GMTCL-PREVALENCE is a proof of concept implementation of the Object Prevalence object persistence concept by Klaus Wuestefeld.
