I built a new JSON Logic gem for Ruby because the existing options weren’t cutting it for my projects; The current alternatives have very little compliance with the current JSON Logic standard or fail on edge cases that matter when you’re sharing rules between Ruby and JavaScript, so I wrote a Gem with 92% compliance coverage currently and made it how I’d like it to be: Ruby 2.7+ compatible, zero deps and very simple to use (:
