arrays - 将数组拆分为散列

我有一个值数组。例如:

arr = [
           "1", "customer_one", "down",
           "2", "up",
           "3", "down",
           "4", "customer_two", "up",
           "5", "for_vpn", "down"
         ]

这些值描述了路由器的端口信息。我想得到这样的哈希数组:

[
  {:name=>"1", :description=>"customer_one", :state=>"down"},
  {:name=>"2", :description=>"", :state=>"up"},
  {:name=>"3", :description=>"", :state=>"down"},
  {:name=>"4", :description=>"customer_two", :state=>"up"},
  {:name=>"5", :description=>"for_vpn", :state=>"down"}
]

请注意，在 arr[3] 和 arr[4] 、 arr[5] 和 arr[6] 之间没有具有描述值的元素，但结果哈希必须包含等于空字符串 :description=>"" 的键描述

最佳答案

arr
.slice_before{|e| e !~ /\D/}
.map do
  |name, description = "", state|
  {name: name, description: description, state: state}
end
