How to split a string by newline in shopify?

In Shopify, you can split a string by newline using the split filter provided by Liquid, the templating language used in Shopify.

To split a string by newline, you can make use of the following code:

1
2

{% assign lines = your_string | split: '
' %}

Explanation:

• your_string is the variable or string that you want to split.
• split is the Liquid filter used to split the string.
• ' ' is the delimiter used to split the string by newline. The backslash is used to escape the special character n, representing a newline.

After splitting the string, you can access the individual lines using lines[0], lines[1], and so on.

Example usage: Let's say you have a string that contains multiple lines, stored in the variable content. If you want to split it into individual lines and loop through them, you can do the following:

1
2
3
4
5
6
7
8
9

{% assign content = "Line 1
Line 2
Line 3" %}
{% assign lines = content | split: '
' %}

{% for line in lines %}
  <p>{{ line }}</p>
{% endfor %}

This code will:

Note: The split filter is available in the newer Shopify themes. If you are using an older theme, you may need to upgrade or check the Liquid version in use.
