Mikka, The pallet/thread-expr library has the macros you're looking for:
https://github.com/pallet/thread-expr These would allow you to write: (use 'pallet.thread-expr) (-> {} (status code) (content-type "application/json;charset=utf-8") (when-> (= error-type :unauthorized) (header "WWW-Authenticate" "Basic realm=\"my-realm\"")) (when-not-> (= request-method :head) (assoc :body (json-str ...)))) The tests provide a decent set of examples: https://github.com/pallet/thread-expr/blob/develop/test/pallet/thread_expr_test.clj Cheers, Sam On Tue, Jan 10, 2012 at 8:06 AM, Miikka Miettinen < miikka.mietti...@gmail.com> wrote: > Hi, > > I sometimes find myself wanting to write simple conditional expressions > inside -> and ->>.
