Github Blog : Start

Getting started Liquid Template Language

Github Blog 테마의 Jekyll minimal mistakes를 사용하기로 결정을 하고 Liquid Template Language를 학습하기 위해 liguid 가이드 홈페이지 기반으로 학습을 진행하였습니다.

Operator

In tags with more than one and or or operator, operators are checked in order from right to left.

Operator	description
==	equals
!=	does not equal
>	greater than
<	less than
>=	greater than or equal to
<=	less than or equal to
or	logical or
and	logical and

{% if true and false and false or true %}
  This evaluates to false, since the tags are checked like this:

  true and (false and (false or true))
  true and (false and true)
  true and false
  false
{% endif %}

Contain

Contains checks for the presence of a substring inside a string.

{% if product.title contains "Pack" %}
  This product's title contains the word Pack.
{% endif %}

Truthy and falsy

All values in Liquid are truthy except nil and false.

if

<!-- If customer.name = "anonymous" -->
{% if customer.name == "kevin" %}
  Hey Kevin!
{% elsif customer.name == "anonymous" %}
  Hey Anonymous!
{% else %}
  Hi Stranger!
{% endif %}

unless

This would be the equivalent of doing the following

{% unless product.title == "Awesome Shoes" %}
	These shoes are awesome!
{% endunless %}
<!-- equivalent -->
{% if product.title != "Awssome Shoes" %}
	These shoes are awesome!
{% endif %}

case/when

{% assign handle = "cake" %}
{% case handle %}
  {% when "cake" %}
     This is a cake
  {% when "cookie", "biscuit" %}
     This is a cookie
  {% else %}
     This is not a cake nor a cookie
{% endcase %}

for

{% for i in (1..5) %}
  {% if i == 4 %}
    {% break %}
  {% else %}
    {{ i }}
  {% endif %}
{% endfor %}

continue

{% for i in (1..5) %}
  {% if i == 4 %}
    {% continue %}
  {% else %}
    {{ i }}
  {% endif %}
{% endfor %}

limit

<!-- if array = [1,2,3,4,5,6] -->
{% for item in array limit:2 %}
  {{ item }}
{% endfor %}
<!-- output : 1 2 -->

offset

<!-- if array = [1,2,3,4,5,6] -->
{% for item in array offset:2 %}
  {{ item }}
{% endfor %}
<!-- output : 3 4 5 6 -->

range

{% for i in (3..5) %}
  {{ i }}
{% endfor %}

{% assign num = 4 %}
{% assign range = (1..num) %}
{% for i in range %}
  {{ i }}
{% endfor %}

reversed

<!-- if array = [1,2,3,4,5,6] -->
{% for item in array reversed %}
  {{ item }}
{% endfor %}

cycle (group)

{% cycle "first": "one", "two", "three" %}
{% cycle "first": "one", "two", "three" %}
{% cycle "second": "one", "two", "three" %}
{% cycle "second": "one", "two", "three" %}
<!-- output : one two one two -->

tablerow

<table>
{% tablerow product in collection.products %}
  {{ product.title }}
{% endtablerow %}
</table>
