"description": "======================\nmegrok.resourceviewlet\n======================\n\n`megrok.resourceviewlet` is a package meant to include resources\nusing layer, context and view discriminations.\n\n\nSetup\n=====\n\nLet's import and init the necessary work environment::\n\n >>> import grokcore.component as grok\n >>> from grokcore import view, viewlet\n >>> from zope.app.wsgi.testlayer import Browser\n\n >>> browser = Browser()\n >>> browser.handleErrors = False\n\n\nLibrary\n=======\n\nWe first declare a resource. We'll include it in our page::\n\n >>> from fanstatic import Resource, Library\n >>> myLibrary = Library('test_library', 'ftests/resources')\n >>> Thing = Resource(myLibrary, 'thing.js')\n\nThis step is done by an entry point. For the testing, we do it by hand::\n\n >>> from zope.fanstatic.zcml import create_factory\n >>> from zope.component import getGlobalSiteManager\n >>> from zope.publisher.interfaces.browser import IBrowserRequest\n >>> from zope.interface import Interface\n\n >>> resource_factory = create_factory(myLibrary)\n >>> getGlobalSiteManager().registerAdapter(\n ... resource_factory, (IBrowserRequest,), Interface, myLibrary.name)\n\n\nComponents\n==========\n\nTo demonstrate our resource viewlet, we first need a page to\nrender. This page contains a content provider named 'resources'::\n\n >>> from zope.interface import Interface\n\n >>> class Index(view.View):\n ... view.require(\"zope.Public\")\n ... view.context(Interface)\n ...\n ... template = view.PageTemplate(\"\"\"\n ... \n ... \"\"\")\n\n >>> grok.testing.grok_component('index', Index)\n True\n\n\nManager\n-------\n\nWe now register a content provider named 'resources'. It will be a\nResourcesManager. An ResourcesManager is a component\ndedicated in rendering ResourceViewlets::\n\n >>> from megrok.resourceviewlet import ResourcesManager\n\n >>> class Resources(ResourcesManager):\n ... viewlet.context(Interface)\n \n >>> grok.testing.grok_component('resources', Resources)\n True\n\n\nViewlet\n-------\n\nNow, we register a ResourceViewlet, including our resource. The\ndeclaration is very straightforward::\n\n >>> from megrok.resourceviewlet import ResourceViewlet\n\n >>> class SomeViewlet(ResourceViewlet):\n ... viewlet.context(Interface)\n ... resources = [Thing]\n\n >>> grok.testing.grok_component('viewlet', SomeViewlet)\n True\n\nBy default, a ResourceViewlet is registered for an instance of\nResourcesManager. Most of the time, a page contains only one of\nthese content providers. If it's not the case, make sure to provide\nyour own `viewletmanager` directive value.\n\n\nRendering\n=========\n\nRendering our page should render the ResourcesManager and\ntherefore, include our resource::\n\n >>> browser.open('http://localhost/@@index')\n >>> print browser.contents\n \n \n \n\nIt works ! Enjoy.\n\n\nChangelog\n=========\n\n0.2 (2011-01-18)\n----------------\n\n* ``megrok.resourceviewlet`` now works and depends on ``fanstatic``.\n* Dependencies has been greatly reduced.\n\n0.1 (2009-12-24)\n----------------\n\n* Initial release",
