Defined in:
lib/merb-core/controller/mixins/controller.rb

#render_chunked(&blk) ⇒ Object

Renders the block given as a parameter using chunked encoding.

Parameters

&blk

A block that, when called, will use send_chunks to send chunks of data down to the server. The chunking will terminate once the block returns.

Examples

def stream
  prefix = '<p>'
  suffix = "</p>\r\n"
  render_chunked do
    IO.popen("cat /tmp/test.log") do |io|
      done = false
      until done
        sleep 0.3
        line = io.gets.chomp

        if line == 'EOF'
          done = true
        else
          send_chunk(prefix + line + suffix)
        end
      end
    end
  end
end
