anthill.tal.macrorenderer 0.2.1

Rendering ZPT macros from python code made easy

Introduction

This package renders macros from a given page template using pure python.

Sometime you may want to use page templates like code libraries where for each functionality you have one macro. Calling macros is no problem using ZPT use-macro but how do you call macros from pure python code and also pass parameters? Because there do not seems to be an obvious solution for this problem (especially the parameters part) this package was created.

Render macro with name macroname from a given page template:

>>> from anthill.tal.macrorenderer import MacroRenderer
>>> template = ViewPageTemplateFile('template.pt')
>>> renderer = MacroRenderer(template, 'macroname')
>>> print renderer(data={'option1' : 42})

Sometimes you get an exception about not enough context being provided to the renderer (or for prior versions a TypeError).

A fix is easy: Simply add a context=self.context to the MacroRenderer call:

>>> renderer = MacroRenderer(template, 'macroname', context=self.context)
