Jekyll Paginate Error Fix

In this tutorial, you'll learn about Jekyll Paginate Error Fix. We cover key concepts, practical examples, and best practices.

The Problem

Liquid Exception: Liquid syntax error (line 15): Expected end of string but found pipe in "paginator.posts"

Jekyll's paginate plugin has specific syntax requirements. Using unsupported Liquid filters causes errors.

Wrong

{% for post in paginator.posts limit:5 %}
  <h2>{{ post.title }}</h2>
{% endfor %}

Output: Liquid syntax error: Expected end of string but found pipe

The limit filter is not supported on paginator.posts. The paginator already controls the number of posts.

Right

Configure pagination in _config.yml:

paginate: 5
paginate_path: "/blog/page:num/"

In your index.html:

{% for post in paginator.posts %}
  <h2><a href="{{ post.url }}">{{ post.title }}</a></h2>
{% endfor %}

{% if paginator.total_pages > 1 %}
<div class="pagination">
  {% if paginator.previous_page %}
    <a href="{{ paginator.previous_page_path }}">Previous</a>
  {% endif %}
  Page {{ paginator.page }} of {{ paginator.total_pages }}
  {% if paginator.next_page %}
    <a href="{{ paginator.next_page_path }}">Next</a>
  {% endif %}
</div>
{% endif %}

Output: paginated blog listing with Previous/Next navigation.

Prevention

• Install jekyll-paginate gem and add it to plugins in config
• Set paginate and paginate_path in _config.yml
• Use paginator.posts directly without additional Liquid filters

Common Mistakes with paginate error

1. Using foldl instead of foldl' causing stack overflow on large lists
2. Forgetting deriving (Show, Eq) on custom data types needed for debugging
3. Placing the wildcard pattern first in case expressions, making all subsequent patterns unreachable

These mistakes appear frequently in real-world JEKYLL code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
