Failing on extra keys

Hi. You need to wrap Specs into Spec Records as clojure.spec doesn't support runtime conforming and core Specs can't be extended. There is a Issue describing why and a patch to fix it. Go vote it up.

I don't think we are interested in turning spec into a transformation engine via conformers, so I suspect we are probably not interested. However, I'll leave it for Rich to assess.

Before / if ever that is resolved, instead of:

(require '[spec-tools.core :as st])
(require '[clojure.spec.alpha :as s])

(s/def ::attr #{"value"})
(s/def ::has-key (s/keys :opt [::attr]))

(st/conform
  ::has-key
  #:noextrakey.clj.core
      {:attr "value"
       :other-attr "still-valid?"}
  spec-tool/fail-on-extra-keys-conforming)
; #:noextrakey.clj.core{:attr "value", :other-attr "still-valid?"}

you need to:

(require '[spec-tools.core :as st])
(require '[clojure.spec.alpha :as s])

(s/def ::attr #{"value"})
(s/def ::has-key (st/spec (s/keys :opt [::attr])))

(st/explain
  ::has-key
  #:noextrakey.clj.core
      {:attr "value"
       :other-attr "still-valid?"}
  spec-tool/fail-on-extra-keys-conforming)

Alright, that's clear. Thanks!
