Is it possible to paginate collection data?

I’ve set up some collections, and have indices which I’d like to paginate over the resulting data. I was expecting to be able to use the following template:

---
layout: layouts/default
title: 'Journal'
pagination:
  data: collections.posts
  size: 8
permalink: '/journal/page/{{ pagination.pageNumber }}.html'
---
{% for item in pagination.items %}
  {% include "item/post" %}
{% endfor %}

I might have misunderstood this feature, but is it possible to use collection data as a basis for pagination?

To answer your second question @paulrobertlloyd, the permalink front matter key can use template syntax (including if statements). I’ve added a test for this in the test suite, but the following will work:

---
pagination:
  data: items
  size: 2
items:
  - item1
  - item2
  - item3
  - item4
permalink: paged/{% if pagination.pageNumber > 0 %}page-{{ pagination.pageNumber }}/{% endif %}index.html
---

hey I am still struggling to make paged paginations. Is there an example repo or an output of what this code does? I tried it but it doesn’t do what I thought it would. Thanks!

And it already is. Sigh. Stupid me not CTRL+F on the page. Sorry for the noise!
