Hi, (defmacro with-resources [bindings close-fn & body] (let [[x v & more] bindings] `(let [~x ~v] (try ~(if-let [more (seq more)] `(with-resources ~more ~close-fn ~@body) `(do ~@body)) (finally (~close-fn ~x))))))
user=> (macroexpand-1 '(with-resources [x 1] close foo bar)) (clojure.core/let [x 1] (try (do foo bar) (finally (close x)))) user=> (macroexpand-1 '(with-resources [x 1 y 2] close foo bar)) (clojure.core/let [x 1] (try (user/with-resources (y 2) close foo bar) (finally (close x)))) You can call with-resource recursively. This has the added benefit of closing the resources in reverse order. Sincerely Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
