Defining 'all-purpose' macros
To define an 'all-purpose' macro, i.e. a macro, that can render
objects of (nearly) any type and thus be accessed from any
other page template, just set a very general context for your macro
view:
Macros are a way to define a chunk of presentation in one template,
and share it in others. Changes to the macro are immediately reflected
in all of the places, that share it.

1 2 3 4 5 | from zope.interface import Interface
import grok
class Master(grok.View):
grok.context(Interface)
|
and reference the macros of the associated pagetemplate like this:
context/@@master/macros/<macro-name>
Because the macros in Master now are 'bound' (in fact their view is bound) to Interface and every Grok application, model or container implements some interface, the Master macros will be accessible from nearly every other context. Master promises to be a view for every object, which implements Interface.
