This replaces Jekyll's include tag and adds support for conditional rendering, in-line filters and including partials from Octopress Ink plugins.

If you're using bundler add this gem to your site's Gemfile in the :jekyll_plugins group:

group :jekyll_plugins do
  gem 'octopress-include-tag'
end

Then install the gem with Bundler

$ bundle

To install manually without bundler:

$ gem install octopress-include-tag

Then add the gem to your Jekyll configuration.

gems:
  -octopress-include-tag

Use this just like the regular Jekyll include tag.

{% include foo.html %}                // renders _includes/foo.html
{% include foo.html happy="yep"  %}   // samea as above but {{ include.happy }} == "yep"

Include partials stored as a variable.

{% assign post_sidebar = "post_sidebar.html" %}
{% include post_sidebar %}   // renders _includes/post_sidebar.html

Include partials conditionally, using if, unless and ternary logic.

{% include sidebar.html if site.theme.sidebar %}
{% include comments.html unless page.comments == false %}
{% include (post ? post_sidebar : page_sidebar) %}

Filter included partials.

{% include foo.html %}           //=> Yo, what's up
{% include foo.html | upcase %}  //=> YO, WHAT'S UP

Yes, it can handle a complex combination of features… but can you?

{% include (post ? post_sidebar : page_sidebar) | smart_quotes unless site.theme.sidebar == false %}

It's easy to include a partial from an Ink theme or plugin.

Here's the syntax

{% include [plugin-slug]:[partial-name] %}

Some examples:

{% include theme:sidebar.html %}   // Include the sidebar from a theme plugin
{% include twitter:feed.html %}    // Include the feed from a twitter plugin

Plugins and themes use this tag internally too. For example, the octopress-feeds plugin uses the include tag to render partials for the RSS feed.

{% for post in site.articles %}
  <entry>
    {% include feeds:entry.xml %}
  </entry>
{% endfor %}

If you want to make a change to the entry.xml partial, you could create your own version at _plugins/feeds/includes/entry.xml. Now whenever {% include feeds:entry.xml %} is called, the include tag will use your local partial instead of the plugin's partial.

Note: To make overriding partials easier, you can copy all of a plugin's partials to your local override path with the Octopress Ink command:

$ octopress ink copy [plugin-slug] [options]

To copy all includes from the feeds plugin, you'd run:

$ octopress ink copy feeds --includes

This will copy all of the partials from octopress-feeds to _plugins/feeds/includes/. Modify any of the partials, and delete those that you want to be read from the plugin.

To list all partials from a plugin, run:

$ octopress ink list [plugin-slug] --includes

Note: When a plugin is updated, your local partials may be out of date, but will still override the plugin's partials. Be sure to watch changelogs and try to keep your modifications current.
