Octopress Return Tag

Render Liquid variables with conditions and filters.

Add this line to your application's Gemfile:

gem 'octopress-return-tag'

And then execute:

$ bundle

Or install it yourself as:

$ gem install octopress-return-tag

Next add it to your gems list in Jekyll's _config.yml

gems:
  - octopress-return-tag

Here's a simple example where you can see that it does the same thing as the standard liquid render braces.

{{ site.author }}                  //=> Bobby Tables
{% return site.author %}           //=> Bobby Tables

{{ site.author | upcase }}         //=> BOBBY TABLES
{% return site.author | upcase %}  //=> BOBBY TABLES

Conditional returns.

{% return "→ " if linkpost %}
{% return "★ " unless linkpost %}
{% return post.external-url || post.url %}
{% return (post ? post.date : page.date ) | datetime | date_to_xmlschema %}

Why is this useful? Here's how you might add title markers for a linkpost blog.

{% return (linkpost ? "→ " : "★ ") %}{{ post.title }}

Now here's what you'd have to do with standard liquid tags:

{% if linkpost %}
  {% capture title %}→ {{ post.title}}{% endcapture %}
{% else %}
  {% capture title %}★ {{ post.title }}{% endcapture %}
{% endif %}
{{ title }}

See how if and capture make it harder to read a template file? That's why the return tag exists.
