z3c.resourceinclude 0.1

Machinery to include web resources based on request layer.

Overview

• Cascading stylesheets (.css)

• Kinetic stylesheets (.kss)

• Javascript (.js)

Usage

The package operates with browser resources, registered individually or using the resource directory factory.

A simple example:

<configure xmlns="http://namespaces.zope.org/zope"
          xmlns:browser="http://namespaces.zope.org/browser">

  <include package="z3c.resourceinclude" file="meta.zcml" />
  <include package="z3c.resourceinclude" />

  <browser:resource name="example.css" file="example.css" />

  <browser:resourceInclude
       layer="zope.publisher.interfaces.browser.IDefaultBrowserLayer"
       include="example.css"
   />

</configure>

This registration means that whenever the request provides IDefaultBrowserLayer the resource named ‘example.css’ will be included on the page.

To render HTML snippets that include applicable resources, a content provider is provided, see z3c/resourceinclude/provide.py.

A convenience method is provided to require a given resource layer:

>>> from z3c.resourceinclude import provide
>>> provide(IMyLayer)

Ordering

Resources will be included in the order they’re registered for inclusion; within an include-definition, order is respected only for resources of similar kind.
