LiquidValidator

Is a simple way to validate your Liquid Template strings before creating a Liquid Template object without raising error. If you do want to raise an error and handle yourself consider then this gem isn't for you.

This is a very simple gem, that is the point.

Add this line to your application's Gemfile:

gem 'liquid-validator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install liquid-validator

good_tmpl = "Your name is {{name}}"
validator = LiquidValidator::Validator.new(good_tmpl)
validator.valid? # true
validator.errors # []

bad_tmpl  = "Your name is {{name"
validator = LiquidValidator::Validator.new(bad_tmpl)
validator.valid? # false
validator.errors # ["Syntax Error: ..."] (Array of strings)

If you're using liquid version 3 and greater you can adjust the strictness of template validation. The default is :strict which is the suggested level. The levels match error-modes. You can adjust the error mode via:

good_tmpl = "Your name is {{name}}"
validator = LiquidValidator::Validator.new(good_tmpl, error_mode: :lax)
validator.valid? # true
validator.errors # []

bad_tmpl  = "Your name is {{name"
validator = LiquidValidator::Validator.new(bad_tmpl, error_mode: :lax)
validator.valid? # true
validator.errors # []

Note - That in LiquidValidator::Validator.new(tmpl) tmpl is a string.
