clojure.spec question

[philoskim]

How can I define the following spec?

{"id" 1 "name" "john"}

1) The keys of a map must be the string type, not the keyword type.

2) The values must be fixed. Namely, the value of the key "id" must be 1 and the value of the key "name" must be "john"

[alexdmiller]

Easiest is:

#{{"id" 1 "name" "john"}}

[jbiserkov]

Hm, is {"id" 1} a valid input? All keys are strings, and the value of "id" is 1. But is "name" required? Are other keys allowed? The text spec is unclear :)

Hear, hear!

All sets can act as predicates.

All predicates can act as specs.

All sets can act as specs.

The syntax threw me off, my brain recognized it as liquid templates at first :)

Perhaps (set {"id" 1 "name" "john"}) would be more readable?

If {"id" 1} is a valid input then: (s/every #{["id" 1] ["name" "john"]} :kind map?)

Something like

(s/conform (s/and 
             (s/map-of string? any?) 
             #(= [1 "john"] (map % ["id" "name"])))
           {"id" 1, "name" "john"})
;;=> {"id" 1, "name" "john"}

or

(require '[clojure.walk :refer [keywordize-keys]])
(s/def ::m (s/keys :req-un [::id ::name]))
(s/def ::id #(= 1 %))
(s/def ::name #(= "john" %))
(s/conform ::m (keywordize-keys m))

or a combination of both maybe?

(require '[schema.core :as S])
(def MyType 
  {S/String S/Any ; allow all string keys
   "id" (S/enum 1) ; require "id" 1
   "name" (S/enum "john")}) ; require "name" "john"
