At the moment, there appears to be no documented way to format the output of the various to_yaml methods.  They all accept an options hash but the documentation does not specify what options may be passed.

Also, the use of to_yaml_style is undocumented.

   class Array
      def to_yaml_style
        :inline
      end
   end

results in inline formatting of the resulting yaml.  This is not documented anywhere but works. 

This is further described in [1] and [2].
