how to validate email in clojure

I want to validate a email using clojure. How can I do it.

(defn validate-email [email]

    )

I want to know how will be the function body writeen using regular expressions.

Solution 
  • (defn validate-email
  [email]
  (let [pattern #"[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"]
    (and (string? email) (re-matches pattern email))))
