I would expect the props from the vector to be passed to the schema.

(m/properties
 (m/schema :at.least/ten
           {:registry (merge
                       (m/default-schemas)
                       {:at.least/ten [int? {:min 10}]})})) ;; => nil

int? is just a predicate, does not support properties, :int is a real schema. Try [:int {:min 10}] instead.

would be nice to get a warning out of this, but not there yet.

@U055NJ5CC predicate schemas probably support some properties, just not these

aha, thanks 👍 this would imply that there is not a real schema equivalent of inst? , right? how come?

there is a separate ticket for making good time schemas, e.g. :time, :date , …

but, bumped into the missing :inst just yesterday, so, hear you.

(defn -int-schema [] (-simple-schema {:type :int, :pred int?, :property-pred (-min-max-pred nil)})) and int? is (-simple-schema {:type 'int?, :pred int?})

We could register property-pred for predicates where it makes sense

.... though I might prefer just removing property predicates completely

I second that, speaking as a relatively new user coming from spec I expected int? and :int to be equivalent

but to end I would just like to say you guys but out some amazing libraries. i've learned a ton from reading your code. thanks!

shouldn't this also work?

(m/properties
 (m/schema :at.least/ten
           {:registry (merge
                       (m/default-schemas)
                       {:at.least/ten [:int {:doc "this number needs to be at least ten"
                                             :custom/attrib :tranmogrify
                                             :min 10}]})}))

aha, malli.core/deref
