Subject: YAML::quick_emit api change


i had a method like this in my OrderedHash class


     def yaml_inline= bool
       unless defined? @__yaml_inline_meth
         @__yaml_inline_meth =
           lambda {|opts|
             YAML::quick_emit(id, opts) {|emitter|
               emitter << '{ ' << map{|kv| kv.join ': '}.join(', ') << ' }'
             }
           }
         class << self
           def to_yaml opts = {}
             @__yaml_inline ? @__yaml_inline_meth[ opts ] : super
           end
         end
       end
       @__yaml_inline = bool
     end


which toggled the yaml output style from the standard one to an inline one.  it
blows up now (1.8.4) with

   NoMethodError: undefined method `<<' for nil:NilClass

and indeed


   jib:~ > ruby -r yaml -e ' YAML::quick_emit(object_id){|e| p [RUBY_VERSION, e.class]; exit} '
   ["1.8.1", YAML::Syck::Emitter]


   harp:~ > ruby -r yaml -e ' YAML::quick_emit(object_id){|e| p [RUBY_VERSION, e.class]; exit} '
   ["1.8.4", YAML::Syck::Out]


i checked in the docs and am reading the source now - but the fix isn't jumping
out at me.  any ideas?

ps.  what's with the tab madness in the yaml src!  ick.

cheers.
