  Renders a translation with a fallback if the translation is missing.
  Currently, the 't' filter can't set a default value.

  Accepts:
  - key {string} - The translation key
  - t {string} - The contents of the already translated key
  - fallback {string} - The fallback translation
  - as_json {boolean} - Whether to return the translation as JSON

  Usage:
  {% render 'utility.translate', t: 'actions.add_to_cart', fallback: 'Add to cart' %}
{% endcomment %}

{% liquid
  assign output = ''

  if key != blank
    assign output = key | t
  else
    assign output = t
  endif

  if output contains 'Translation missing:'
    assign output = fallback
  endif

  if as_json
    assign output = output | json
  endif

  echo output
%}
