Question

我有一系列值。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。我想得到像这样的哈希数组：

[
  {: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]之间，arr[5]和arr[6]之间没有包含描述值的元素，但结果哈希必须包含键描述等于空字符串:description=>""

Answer 1

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

将数组拆分为哈希值
