how to implement a "decorator" pattern that processes an entire template

[Jacob G]

I'd like to have a way for a template to process an entire chunk of data, particularly to:

1. create a zip file of entire template
2. create an excel file, which takes the inner contents and creates a zip file along with other meta data

Is the macro tag the only way to do this? i.e. along the lines of:

{% macro my_contents(data) %}

{% endmacro %}

{{ my_contents(data) | zip }}

For clarity, I think I'd prefer a syntax like this:

{% pipeline zip %}
... MY TEMPLATE CONTENTS ...
{% endpipeline %}

Thoughts?

Hi Jacob,

I'm not entirely sure I understand what you mean, but I think perhaps the `filter` tag would be useful to you: http://mozilla.github.io/nunjucks/templating.html#filter
