An open source framework dedicated to rich web applications development in Python Nagare is a components based framework: a Nagare application is a composition of interacting components each one with its own state and workflow kept on the server. Each component can have one or several views that are composed to generate the final web page. This enables the developers to reuse or write highly reusable components easily and quickly. Thanks to Stackless Python, Nagare is also a continuation-based web framework which enables to code a web application like a desktop application, with no need to split its control flow in a multitude of controllers and with the automatic handling of the back, fork and refresh actions from the browser. Nagare's component model and use of the continuation are inherited from the famous Seaside Smalltalk framework.Nagare doesn't follow the status quo established by the classic frameworks of the Java, Python, Php and Ruby worlds:· no templating language· no explicit URL routing / mapping· no controllers proliferation· no manual management of the HTTP request / response cycles· no global session object· no REST by defaultWhen you forget all of that, what do you get ?You get a powerful framework dedicated to web applications development, in opposition to simple content publishing.You get a truly component based framework where the application is a dynamic set of autonomous components, each one following its own independent control flow and maintaining its own private state.You get a framework where every web page is the composition of views from several components.You get a framework where the HTTP connectionless request / response cycle, the refresh, back and fork actions of the browser, don't break the normal control flow of the application.You get a framework with natively integrated Web 2.0 features.You get a framework where the web applications are developed in the same way as the desktop applications. Here are some key features of "Nagare": · the views of the components are Python methods rendering a DOM tree, built in programmatic XHTML or from a template, · the control flow of the components is coded in Python, thanks to the continuation, · data management in DBMS using SQLAlchemy or its declarative layer Elixir, · if a Python function is given instead of an expected Javascript code, Nagare automatically generates a translation from Python to Javascript. · WSGI: binds the application to several possible publishers, · lxml: generates the DOM trees and brings to Nagare the full set of XML features (XSL, XPath, Schemas ...), · setuptools: installs, deploys and extends the Nagare framework and the Nagare applications too, · PEAK Rules: generic methods are heavily used in Nagare, to associate views to components, to define security rules, to translate Python code to Javascript ... · WebOb: for its Request and Response Objects. · No more manual URL mapping. Nagare directly associates a Python callback to a link or a field of a form. · No global session object. All the states of all components are kept on the server. · Easy development with Nagare own Python multi-threaded server including automatic reloading and possible clustering deployment using a memcached server. · Automatic conversion of the parameters received to Unicode and automatic generation of UTF-8 encoded web pages. Nagare is a full Unicode framework. · Possible automatic generation of, always 100% valid, XHTML or HTML according to the browser capability. · Transparent Ajax rendering of a component, without any Python or Javascript code to add. Requirements: · Python
