I want to migrate gradually. The way needs explicit big bang conversion. ---------------------------------------- Feature #6910: Loading syck's broken yaml with psych https://bugs.ruby-lang.org/issues/6910#change-29001 Author: naruse (Yui NARUSE) Status: Assigned Priority: Normal Assignee: tenderlovemaking (Aaron Patterson) Category: ext Target version: 2.0.0 You know, syck outputs wrong yaml. For example, syck works as following: ruby-1.9.2 > ["\u3042",Time.at(0).to_s].to_yaml => "--- \n- \"\\xE3\\x81\\x82\"\n- 1970-01-01 09:00:00 +09:00\n" It should be ruby-1.9.3 > ["\u3042",Time.at(0).to_s].to_yaml => "---\n- ���\n- '1970-01-01 09:00:00 +0900'\n" syck's dump of Unicode string is interpreted as "\u00E3\u0081\u0082". syck's dump of Time like string is interpreted as Time. It is hard to migrate old data to new and correct data, so it is useful if psych has a such compatibility option. -- http://bugs.ruby-lang.org/
