To expand on what Alex already mentioned. There is no such thing as double-colon keywords. Double-colon is a reader alias mechanism that let the reader resolve them so you can type less.
(ns foo.bar.xyz) ::hello this is resolved at read-time and identical to actually writing :foo.bar.xyz/hello :: without a slash will use the current namespace as the namespace for the keyword. If you have a require for another namespace and use :: with a slash you can use it to resolve your require alias. (ns some.thing (:require [foo.bar.xyz :as x])) ::x/hello again becomes :foo.bar.xyz/hello in your actual program. Nothing :: will ever exist at runtime. So if you want you can always use the fully qualified keyword directly or you can let the require resolve them based on your ns require's. That means you'll get an error if there is no alias to resolve (ns user2) ::user1/foo This is invalid because user2 does not have an alias to user1, instead it is an actual full namespace. :user1/foo would be fine in this case (and identical to ::foo in user1). Or (ns user2 (:require [user1 :as u1])) ::u1/foo Hope that makes things clearer. Cheers, Thomas -- You received this message because you are subscribed to the Google Groups "Clojure" group.
