Shopify: Show all numbers in pagination

gistfile1.txt

{% assign count = paginate.pages %}
{% for part in (1..count) %}
      <li {% if paginate.current_page == part %}class="active"{% endif %}><a href="{{ collection.url }}?page={{ forloop.index }}">{{ forloop.index }}</a></li>
{% endfor %}

While I appreciate this simplistic approach, I found an issue with the search page. Since the search adds a q=search parameter, the query parameter would be lost when changing pages since the href is hardcoded in your example.

I published an updated gist that retains the query parameter by using the generated page.next.url links:
