|
# 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
|
|
#
