Open Source Object Oriented Software

A simple framework for plugin system development with as few dependencies as possible. It is designed to offer a set of very lean classes (plugin managers and plugin interfaces) which can easily be customised by decoration or inheritance. Yapsy v1.x supports Python2 and Python3. Its source package contains versions of the sources for both pythons. Yapsy v2+ supports Python 3 and it's development happens now on https://github.com/tibonihoo/yapsy/ Usage samples, advices and developer's documentations are available on the main website.

Extended C gives Object-Oriented features such as self-referential structure pointers via macros to C, resulting in an object-oriented style. Currently tested in gcc, we hope to stabilize it for other compilers as well, including Borland & Visual Studio.

Runtime library for the JUndo language. See http://verdantium.blogspot.com/

This project offers a collection of resources that can be used to document object models in the Z language. This mainly consists in prelude files for z type checking and latex demo files that use it.

PapaFactory is a header-only C++ library providing three generic abstract factories. The library is licensed under the Boost software license which allows incorporation into propriety software.

Java objects that share parts of immutable graphs. Reused subgraphs have directly or indirectly recursive Elements. Selected components get replaced by new counterparts in Context of Mirrors - translation tables. Deep copies are not involved.

jDSM is a Java library for representing and analyzing Design Structure Matrices (DSM). It can be used to analyze any Java software with regards to modularity.

The Bidirectional Object-oriented Transformation Language (BOTL) is a tool for object-oriented model transformations.

ClassBuilder is freeware CASE tool targeted at the C++ developer, running on Win2K/XP/Vista/7. It lets you create, manipulate and navigate classes, class relations, class members and class methods at a high level of abstraction through a graphical user interface

The API features a layer between the trivial PHP and the low level web GUI (XHTML, XML, Javascript, PDF, Ajax ...). It’s extensible because of its clean and easy structure. The Concept comes with a widget toolkit, many plug-ins, themes and sub-modules.

A small library that provides a powerful and container-less Dependency-Injection mechanism, via AspectJ and Groovy. If you are tired of reams of XML configuration files, managing complex factories and containers, this non-API solution may appeal to you.

The previous home of the Domain-Driven Design sample application implementation.

Extracts dependencies and OO metrics from Java class files produced by most Java compilers. Computes API differences between versions. No source needed. Includes both Swing and command-line interfaces, with XSL stylesheets for formatting output.

DMDF has collection of Frameworks for distribute your domain model. The Domain Model Transportation framework [sub project] let you use your own domain model replace DTO.

A small library that enables interface based duck typing for Java. Based on java.lang.reflect.Proxy

EliteCore Project is a PHP5.1/Javascript/AJAX/XHTML/CSS framework for creating WEB 2.0 applications and services.The basic open-source instalation can be also used as an interactive personal page or BLOG.This project uses the latest features available.

Fast UML is an open-source UML tool with a simple user interface pop-up free. Draw UML diagrams fast, export diagrams to png, jpg and clipboard. It pretends to be the union between Violet and UMLet.

Fragments is a highly sophisticated C++ library for composing classes from freely definable "fragments". Among other things it can be used to create container classes - just by selecting a set of "fragments" to combine.

FunctionalJ is a library which makes it easy to use functional programming patterns in Java, such as representing functions as objects, partial function application, higher-order functions, mapping, folding, and more.

Gnumler is a "mapping framework". It is able to generate Hibernate xml mapping using a GUI, importing data from database or creating it via the embedded editor. It was born as a thesis project at Politecnico di Milano.

Haggler supports the definition, documentation, and implementation of class invariants and method pre-conditions and post-conditions through Java5 annotations.

JUndo is a declarative object-oriented programming language with functional, and intensional programming characteristics. Applications include multi-level undo and sophisticated error recovery. See http://verdantium.blogspot.com/

Library for implementation of interoperable metaobject protocols for dynamic languages running on a Java Virtual Machine.

Jupe is a UML Plugin for Eclipse. It provides support for the creation of UML class diagrams, Java code generation and reverse engineering. Jupe is based on the GEF and UML2 frameworks and supports Eclipse 3.2.

Design by Contract allows a programmer to document a function/class with statements describing behavior. Metacontract implements the PEP-0316 related to this feature for the Python language using meta classes.
