如何让ruby打印完整的回溯而不是截断的？

begin
  # 你的代码
rescue => e
  puts "捕获到异常：#{e.message}"
  puts "回溯信息："
  puts e.backtrace.join("\n")
end

set_trace_func proc { |event, file, line, id, binding, classname|
  if event == 'raise'
    puts "捕获到异常：#{id}"
    puts "回溯信息："
    puts caller.join("\n")
  end
}

abort "程序出现异常" if $!.backtrace

set_trace_func proc { |event, file, line, id, binding, classname|
  if event == 'line'
    puts "#{file}:#{line}"
  elsif event == 'raise'
    puts "捕获到异常：#{id}"
    puts "回溯信息："
    puts caller.join("\n")
  end
}
