Hi ! I am not able to use a set as a predicate function while making the schema. I need to check whether the passed in value belongs inside a set.
(def MySchema [:fn [x] (contains? #{:a :b :c} x)]) :enum , but in that I noticed I needed to list out all the options beforehand. [:enum :a :c :d] , but I want to use the set directly.

Could you use unquote-splice?
(def s #{:a :b :c})
(def MySchema `[:enum ~@s])
(prn MySchema)
;; => [:enum :c :b :a]
(require '[malli.generator :as mg])
(mg/sample MySchema)
;; => (:b :b :a :a :c :c :a :b :a :c)Shagun Agrawal 2024-11-15T15:01:06.323069Z
This worked ! Thanks. Wasn't familiar with this function. Only seen it code snippets in macros. It's evaluating the s, which gives it the set itself, and it's placing those values in it's place. So it becomes [:enum :a :b :c] .

(apply into [:enum] #{:a :b :c}) or similar should also work (on mobile, cannot verify)
