Subject: [ruby-core:43681] [ruby-trunk - Bug #6205][Open] YAML Regexp in anchor gets converted to String


Issue #6205 has been reported by giddie (Paul Dann).

----------------------------------------
Bug #6205: YAML Regexp in anchor gets converted to String
https://bugs.ruby-lang.org/issues/6205

Author: giddie (Paul Dann)
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux]


I'll try to illustrate with code:

YAML:
  ---
  hello: &allow-float
    !ruby/regexp '/hello/'
  bla: *allow-float

RUBY:
  require 'yaml'
 
  config = YAML.load_file('config.yaml')
  puts config.inspect
  puts config['hello'].class
  puts config['bla'].class

OUTPUT:
  {"hello"=>/hello/, "bla"=>"/hello/"}
  Regexp
  String

The Regexp has become a string.  This only seems to happen if the Regexp is at the root of the anchor.

This happens with Ruby 1.9.3p0, but not with 1.9.2p290.
