Vector – clojure – define a data structure for a person

In other languages, how to create structures is very self - evident How would you do such a thing in clojure?

For example, I want to add a person's name, address and phone number (home and mobile)

I guess I want to make a carrier?

Thank you in advance!

Solution

In clojure, you usually use maps to represent this data You can use a flat map:

{:first-name "Jeremy"
 :last-name "Martinson"
 :street "455 Larkspur Dr."
 :city "Baviera"
 :state "California"
 :zip 22611
 :home-phone "(555) 555-5555"
 :mobile-phone "(666) 666-6666"}

Or nested:

{:name {:first "Jeremy"
        :last "Martinson"}
 :address {:street "455 Larkspur Dr."
           :city "Baviera"
           :state "California"
           :zip 22611}
 :phones {:home "(555) 555-5555"
          :mobile "(666) 666-6666"}}

If your data has more or less static schema and you want to use clojure's polymeric features, you can use records:

(defrecord Name [first last])

(defrecord Address [street city state zip])

(defrecord Phones [home mobile])

(defrecord Person [name address phones])

(map->Person
 {:name (map->Name
         {:first "Jeremy"
          :last "Martinson"})
  :address (map->Address
            {:street "455 Larkspur Dr."
             :city "Baviera"
             :state "California"
             :zip 22611})
  :phones (map->Phones
           {:home "(555) 555-5555"
            :mobile "(666) 666-6666"})})

However, in this case, you may only want to use the map Especially the phone records are very ugly
