README.md

Checking a Liquid file's syntax

1. Install liquid-validator: sudo gem install liquid-validator
2. Put the contents of the liquid file you want to try in a file called liquid_to_test.liquid.
3. Put the test_liquid.rb file in the same folder.
4. From that folder, run ruby test_liquid.rb in the terminal

liquid_to_test.liquid

{% if product.title == 'Awesome Shoes' %}
  These shoes are awesome!
{% endif %}

test_liquid.rb

require 'liquid-validator'

template = File.open("liquid_to_test.liquid", "rb").read
validator = LiquidValidator::Validator.new(template)

if validator.valid?
  puts "All fine!"
else
  puts validator.errors.inspect
end
