  parent, @node = @node, node
  if node.children.empty?
    send(:"compile_#{node.type}")
  else
    send(:"compile_#{node.type}") {node.children.each {|c| compile c}}
  end
ensure
  @node = parent
end

#precompiled ⇒ String

def precompiled
  encoding = Encoding.find(@options.encoding)
  return @precompiled.force_encoding(encoding) if encoding == Encoding::ASCII_8BIT
  return @precompiled.encode(encoding)
end

#precompiled_with_ambles(local_names) ⇒ Object

Returns the precompiled string with the preamble and postamble.

Initializes to ActionView::OutputBuffer when available; this is necessary to avoid ordering issues with partial layouts in Rails. If not available, initializes to nil.
