Not sure why NOT EQUAL or EQUAL not working.

Technical Q&A

Thanks in advance.

Object: shop.vendors

vendors: AAA, AAB, ABC, BBB, CCC

{% assign temp_vendor = “” %}

{% assign add_anchor = false %}

{% for vendor in shop.vendors %}
{% if temp_vendor != vendor | slice: 0 %} ← How come this statement always be true?
{% assign temp_vendor = vendor | slice: 0 -%}
{%- assign add_anchor = true %}

{% else %}

{%- assign add_anchor = false %}
{% endif %}

{{ vendor }}

{% endfor %}

Result:

AAA
AAB
ABC
BBB
CCC

Actually, I expect that the result should be as below:

AAA
AAB
ABC
BBB
CCC

[loop 1]
vendor is “AAA”.

add_anchor = false
temp_vendor = “”
When temp_vendor NOT EQUAL “AAA”
temp_vendor “AAA” | slice: 0
temp_vendor = “A”
assign add_anchor → true

[loop 2]

vendor is “AAB”

temp_vendor = “A”
vendor | slice: 0 (“A”)
{% if temp_vendor != vendor | slice: 0 %}

The above statement should be FALSE since “A” != “A”.

How come “A” !=“A” is TRUE?

The next step should be:

{%- assign add_anchor = false %}

Instead of:

{% assign temp_vendor = vendor | slice: 0 -%}
{%- assign add_anchor = true %}
