Jekyll loop notes

Display tags, if they exist

    {% if podcast.tags %}
    <ul>
      {% for tag in podcast.tags %}
        <li>{{ tag }}</li>
      {% endfor %}
    </ul>
    {% endif %}

Displaying items with tag X

<ul>
  {% for podcast in site.podcasts %}
    {% if podcast.tags contains 'funk' %}
      <li>{{ podcast.title }}</li>
    {% endif %}  
  {% endfor %}
</ul>

Sorting, and reversing the array

{% assign sorted_songs = site.pages | sort: 'date' %}

{% for page in sorted_songs reversed %}
  {% if page.categories contains 'song' %}
    <div class="item">
      <a href="{{ site.baseurl }}{{ page.url }}">{{page.song_name}}</a>
    </div>
  {% endif %}
{% endfor %}
