How can I split a string by newline in Shopify?

Question

I have a field in my settings.html where I am expecting the user to input multiple paragraphs separated by two newline characters. I would like to split this string of input into an array of strings, each representing a paragraph.

I would like to do something like this:

{% assign paragraphs = settings.intro | split: '\n' %}
{% for paragraph in paragraphs %}
    <p>
        {{ paragraph }}
    </p>
{% endfor %}

I can't seem to figure out how to refer to the newline character in Liquid. How can I go about doing this? Is there some kind of work around?

Answer 1

Try this:

{% assign paragraphs = settings.intro | newline_to_br | split: '<br />' %}
{% for paragraph in paragraphs %}<p>{{ paragraph }}</p>{% endfor %}
