Hi,
Some feedback and questions, as I've made something similar in the past.
- allow normal fns and classes as a predicates.
- having one global Var for predicates is an antipattern
- can you compose predicates logically (AND/OR)?
- can you validate a contents of the vector?
As an inspiration, the validator I'm using allows for following rules,
which IMHO looks a bit cleaner:
(defn- uri?
"Checks if input is valid URI."
[uri]
(try
(URI. uri)
true
(catch Exception e false)))
(def location-rule {:name String
:lat Number
:long Number})
(def contributor-rule {(required :id) uri?
:gender #{"m" "f"}
:birthDate String
:locales [String]
:homeAddress location-rule})
Best,
Jozef
