Do we know what changed in psych to cause this? Was this the result of a bug before that was fixed? It is fixed on that Rails commit, but it looks like this is not a stable interface if it can break at any time. I expect `to_yaml` to know more about writing valid YAML than me :) ---------------------------------------- Bug #9300: YAML Regression Concerning Escaping of Strings https://bugs.ruby-lang.org/issues/9300#change-43920 Author: schneems (Richard Schneeman) Status: Open Priority: Normal Assignee: tenderlovemaking (Aaron Patterson) Category: Target version: current: 2.2.0 ruby -v: 2.1.0 Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN =begin When you run this code against Ruby 2.1.0 and previous versions you get different results: require 'YAML' yaml1 = {"key" => %Q{<%= ENV["PATH"] %>} }.to_yaml puts yaml1 Ruby 2.1.0 incorrectly escapes the quote --- key: "<%= ENV[\"PATH\"] %>" While previous versions do not.
