I am trying to build a (simple, unweighted) tag cloud with liquid in my jekyll site. The tag cloud renders fine when I use this code:

{% assign sitetags = "" %}

{% for page in site.pages %}

    {% for tag in page.tags %}

        {% unless sitetags contains tag %}

            {% assign sitetags = sitetags | append:tag | append:', ' %}

        {% endunless %}

    {% endfor %} 

{% endfor %} 



{% assign sitetags = sitetags | split:', ' | sort %}

{% for tag in sitetags %}

    {% capture tag_name %}{{ tag }}{% endcapture %}

    <div>

        <a href="/tag/{{ tag_name }}">{{ tag_name }}</a>

    </div>

{% endfor %} 

However, there is one issue: if the name of a tag is contained within another tag, it won't show up in the tag cloud. For example, "art" is contained in "art-history" so it does not show up. In order to deal with this, I tried to fix it, however, it is not working. Here is my code:

{% assign sitetags = "" %}

{% for page in site.pages %}

    {% for tag in page.tags %}

        {% if sitetags contains tag %}

            {% assign sitetags = sitetags | split:', ' %}

            {% assign truetag = true %}

            {% for taggo in sitetags %}

                {% if taggo != tag %}

                    {% continue %}

                {% else %}

                    {% assign truetag = false %}

                    {% break %}

                {% endif %}

            {% endfor %}

            {% if truetag == true %}

                {% assign sitetags = sitetags | append:tag | append:', ' %} 

            {% endif %}

        {% else %}

            {% assign sitetags = sitetags | append:tag | append:', ' %}         

        {% endif %}

    {% endfor %} 

{% endfor %} 



{% assign sitetags = sitetags | split:', ' | sort %}

{% for tag in sitetags %}

    {% capture tag_name %}{{ tag }}{% endcapture %}

    <div>

        <a href="/tag/{{ tag }}">{{ tag }}</a>

    </div>

{% endfor %} 

The reason I am attempting it this way as opposed to just using site.tags is because I have articles/essays in other directories that I am trying to include. When I use site.tags, it only includes the tags that are on the blog posts but not the essays. Essentially, my site has both regular blog posts under /_blog and also essays in a different location, but I want to aggregate the tags of all of these in the same tag cloud.

I would really appreciate advice on what I am doing wrong or how to fix it. Thanks!

Instead of using a string to store your tags, you can use an array.

{% assign sitetags = "" | split:"" %}

{% for page in site.pages %}

  {% if page.tags.size %}

    {% assign sitetags = sitetags | concat: page.tags %}

    {{ sitetags | inspect }} <br>

  {% endif %}

{% endfor %}



{% assign sitetags = sitetags | sort | uniq %}

{{ sitetags | inspect }} <br>



{% for tag in sitetags %}

  <div>

    <a href="/tag/{{ tag }}">{{ tag }}</a>

  </div>

{% endfor %}

I was able to figure this out myself actually. Part of the issue was in initializing the array, so I ended up working with a string instead because I just couldn't get the arrays to work for some reason. I skipped over initialization and went straight to adding items to it. After that all I had to do was just run the uniq filter and it filtered out all the duplicates, so I didn't have to do any string comparison or anything like that.

Here is the solution:

{% for post in site.pages %}

    {% for tag in post.tags %}

        {% assign tagcloud = tagcloud | append:tag | append:', ' %}

    {% endfor %} 

{% endfor %} 



{% assign tagcloud = tagcloud | split:", " | uniq | sort %}



{% for tag in tagcloud %}

    {% capture tag_name %}{{ tag }}{% endcapture %}

    <div>

        <a href="/tag/{{ tag_name }}">{{ tag_name }}</a>

    </div>

{% endfor %}
