# frozen_string_literal: true module Psych ### # Psych::Stream is a streaming YAML emitter. It will not buffer your YAML, # but send it straight to an IO. # # Here is an example use: # # stream = Psych::Stream.new($stdout) # stream.start # stream.push({:foo => 'bar'}) # stream.finish # # YAML will be immediately emitted to $stdout with no buffering. # # Psych::Stream#start will take a block and ensure that Psych::Stream#finish # is called, so you can do this form: # # stream = Psych::Stream.new($stdout) # stream.start do |em| # em.push(:foo => 'bar') # end # class Stream < Psych::Visitors::YAMLTree class Emitter < Psych::Emitter # :nodoc: def end_document implicit_end = !streaming? super end def streaming? true end end include Psych::Streaming extend Psych::Streaming::ClassMethods end end
