Weird behavior if the context variable is "blank"

[amit777]

template:

{% if blank == "true" %} BLANKSTRUE {% else %} NOT TRUE{% endif %}

context:

{
  "blank": "true"
}

if I rename the variable from blank to blanks, the logic works correctly.

blank and empty are reserved names in Liquid. They are used to test for empty strings, arrays and objects (docs).

{% assign foo = "" %}
{% if foo == blank %}BLANK{% else %}NOT BLANK{% endif %}

This behavior is consistent with Shopify/liquid.

Note

In Shopify/liquid, there are some subtle differences between blank and empty, and blank only works if Active Support is installed.
