emitter. * lib/yaml/stream.rb: ditto. * lib/yaml/rubytypes.rb: added Object#yaml_new. * lib/yaml/tag.rb: the tag_subclasses? method now shows up in the class. allow taguri to be set using an accessor. continue support of Object#to_yaml_type. * ext/syck/rubyext.c: new emitter code. yaml_new and yaml_initialize get called, should they be present. consolidated all the diaspora of internal node types into the family below YAML::Syck::Node -- Map, Seq, Scalar -- all of whom are SyckNode structs pointing to Ruby data. moved Object#yaml_new into the node_import and made it the default behavior. the target_class is always called wih yaml_new, prepended a parameter, which is the klass. loaded nodes through GenericResolver show their style. new Resolver#tagurize converts type ids to taguris. * ext/syck/implicit.re: were 'y' and 'n' seriously omitted?? * ext/syck/emitter.c: renovated emitter, walks the tree in advance. consolidated redundant block_styles struct into the scalar_style struct. (this means loaded nodes can now be sent back to emitter and preserve at least its very basic formatting.) * ext/syck/gram.c: headless documents of any kind allowed. * ext/syck/node.c: new syck_replace_str methods and syck_empty_* methods for rewriting node contents, while keeping the ID and other setup info. added syck_seq_assign. * ext/syck/syck.h: reflect block_styles and new node functions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@9141 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
