Liquid

+

To use this language, use the class "language-liquid".

+ +

Comments

+
{% comment %}This is a comment{% endcomment %}
+ +

Control Flow

+ +Liquid provides multiple control flow statements. + +

if

+

+{% if customer.name == 'kevin' %}
+  Hey Kevin!
+{% elsif customer.name == 'anonymous' %}
+  Hey Anonymous!
+{% else %}
+  Hi Stranger!
+{% endif %}
+
+ +

unless

+ +The opposite of if – executes a block of code only if a certain condition is not met. + +

+{% unless product.title == 'Awesome Shoes' %}
+These shoes are not awesome.
+{% endunless %}
+
+ +

case

+ +Creates a switch statement to compare a variable with different values. case initializes the switch statement, and when compares its values. + +

+{% assign handle = 'cake' %}
+{% case handle %}
+  {% when 'cake' %}
+    This is a cake
+  {% when 'cookie' %}
+    This is a cookie
+  {% else %}
+    This is not a cake nor a cookie
+{% endcase %}
+
+ +

for

+ +Repeatedly executes a block of code. + +break = Causes the loop to stop iterating when it encounters the break tag. +continue = Causes the loop to skip the current iteration when it encounters the continue tag. + +

+{% for i in (1..10) %}
+  {% if i == 4 %}
+    {% break %}
+  {% elsif i == 6 %}
+    {% continue %}
+  {% else %}
+    {{ i }}
+  {% endif %}
+{% endfor %}
+
+ +

range

+ +

+{% for i in (3..5) %}
+  {{ i }}
+{% endfor %}
+
+{% assign num = 4 %}
+{% for i in (1..num) %}
+  {{ i }}
+{% endfor %}
