"Get Posts" Tag independent of "the loop".

README.md

Get Posts independent of URL.

As a stand-in to a full-fledged, publicly accessible JSON API, it would be incredibly liberating to have a Handlebars helper which allows us to loop through posts by parameters (maybe query params could even be mixed into the Handlebars context) instead of some internal state dictated by the URL. This would allow for easy creation of "related content", or a "search" function.

_related_posts.hbs

{{#getPosts limit=2 sort='asc' tags='{{tags limit=2 separator=","}}' orderby='published_at'}}
{{#if @first}}
  <h2>Related Posts</h2>
  <ul>
{{/if}}
<li>
  <h3>{{ title }}</h3>
  <a href="{{ url }}"><img src="{{ image.url }}"></a>
</li>
{{#if @last}}
</ul>
{{/if}}
{{/getPosts}}

post.hbs

{{#post}}
<h2>{{ title }}</h2>
{{ content }}
<hr>
{{> related_posts }}
{{/post}}
