Simple Empty Vector Question

2011-06-14 Thread octopusgrabbus
In the following code (from Brian Carper's cow-blog)

(defn login-page
  Page to let an admin log in.
  []
  {:title Login
   :body [:div [:h3 Log in]
  (form-to [:post /login]
   (form-row Username username text-field)
   (form-row Password password password-field)
   (submit-row Log in))]})

on the third line there are empty vector brackets. I believe this is
defining the function as having now parameters. Is that correct?

Thank you.

Yes that is correct. These forms are equivalent:

(defn login-page [] ...)

(def login-page (fn []  ))


Thanks,
Ambrose
