[Zope-dev] ZPatterns: SkinScript discovery

[Steve Alexander]

I just found out that you can access all sorts of useful methods in
SkinScript from the magical "_" namespace variable.

Let's say I have a DataSkin that has a propertysheet "journey", which
has a "steps" property of type "lines". I can expose its "steps"
property as an attribute, and also a neatly formatted version of the
same, using this SkinScript:

WITH self.propertysheets.get('journey') COMPUTE
  steps=getProperty('steps'),
  steps_comma_sep=_.string.join(self.steps, ', ')
