在记录ruby代码时是否有特定的代码约定?例如，我有以下代码片段:

require 'open3'

module ProcessUtils

  # Runs a subprocess and applies handlers for stdout and stderr
  # Params:
  # - command: command line string to be executed by the system
  # - outhandler: proc object that takes a pipe object as first and only param (may be nil)
  # - errhandler: proc object that takes a pipe object as first and only param (may be nil)
  def execute_and_handle(command, outhandler, errhandler)
    Open3.popen3(command) do |_, stdout, stderr|
      if (outhandler)
        outhandler.call(stdout)
      end
      if (errhandler)
        errhandler.call(stderr)
      end
    end
  end
end

这个猜想是可以的，但是也许有更好/更好的文档实践?
