Subject: [ruby-core:59323] [ruby-trunk - Bug #9300] YAML Regression	Concerning Escaping of Strings


Issue #9300 has been updated by Eregon (Benoit Daloze).


It should as well round-trip data across versions, which it seems it does in this case.

Yet, I find it worrying quoting is changed in a minor version, should not the YAML spec be clear about this?

Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN

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. Here is my original document for debugging this issue:
