Liquid: add simple empty keyword

[JaKXz]

Hey @RunDevelopment here's an easy one :)

I have one quick question though: I want to add an object token that is any one of the following keywords, sourced from the liquid reference

address , all_country_option_tags , article , block , blog , cart , checkout , collection , color , comment , country , country_option_tags , currency , current_page , current_tags , customer , customer_address , date , discount_allocation , discount_application , external_video , filter , filter_value , font , forloop , form , fulfillment , generic_file , gift_card , group , handle , image , line_item , link , linklist , localization , location , measurement , media , metafield , model , model_source , order , page , page_description , page_image , page_title , paginate , part , policy , product , product_option , recommendations , request , robots , routes , rule , script , search , section , selling_plan , selling_plan_allocation , selling_plan_group , shipping_method , shop , shop_locale , sitemap , store_availability , tablerow , tax_line , template , theme , transaction , unit_price_measurement , user_agent , variant , video , video_source

I was going to go with the naive new RegExp([words].join('|')) but I was wondering if you have any better suggestions?

Thanks for the PR @JaKXz!

Use a regex literal, so /\b(?:address|all_country_option_tags|...)\b/. It's the easiest option IMO. (Using regex literals also means that our static analysis tools can deal with them, which is nice.)
