Obtaining the word count from a post in Jekyll for Github Pages?

Question

Here's the code snippet that I'm currently using to see if a blog post exceeds over 120 words. If true, truncate the content and add a "READ MORE" link at the bottom of the post.

<div class="blogs">
  {% for post in site.posts %}
    <article class="post">          
      <h3><a href="{{ site.baseurl }}/{{ site.blogs }}{{ post.title }}">{{ post.title }}</a></h3>

      {% assign wordCount = {{ post.content | size }} %}
      {% if wordCount > 120 %}
        <div class="entry">
            {{ post.content | truncatewords:120}}
        </div>

        <a href="{{ site.baseurl }}{{ post.url}}" class="read-more">Read More</a>
      {% else %}
        {{ post.content }}
      {% endif %}
    </article>
  {% endfor %}
</div>

When I commit this, I received an email from GitHub saying that there's a page error upon building, and nothing else was printed out.

I'm guessing it has to do with {{ post.content }} not being able to filter out the size, so I'm stuck.

How would I obtain the word count of individual blog posts, so that I'm able to truncate some of the posts with over 120 words in them? Thanks in advance.

{{ post.content | size }} gives you the number of characters in post.content string.

If you want to count word in a string, use number_of_words liquid filter.

{% assign wordCount = post.content | number_of_words %}

Note : you have a strange link in the post title {{ site.baseurl }}/{{ site.blogs }}{{ post.title }} I think it's {{ site.baseurl }}{{ post.url}} like in the read more link.
