Maybe I should have already known this, but I am struck by this, and I'd like to confirm it. If I'm working with this code:
https://github.com/drewr/postal/blob/389162cafab08224e50bd6721cac93fe14ca3257/src/postal/support.clj and if, at the REPL, I do this: user=> (require '[postal.support :refer :all]) user=> (clojure.walk/macroexpand-all '(defn make-props [sender {:keys [host port user tls]}] #_=> (doto (Properties.) #_=> (.put "mail.smtp.host" (or host "not.provided")) #_=> (.put "mail.smtp.port" (or port "25")) #_=> (.put "mail.smtp.auth" (if user "true" "false")) #_=> (do-when sender (.put "mail.smtp.from" sender)) #_=> (do-when user (.put "mail.smtp.user" user)) #_=> (do-when tls (.put "mail.smtp.starttls.enable" "true"))))) (def make-props (fn* ([sender p__1201] (let* [map__1202 p__1201 map__1202 (if (clojure.core/seq? map__1202) (. clojure.lang.PersistentHashMap create (clojure.core/seq map__1202)) map__1202) tls (clojure.core/get map__1202 :tls) user (clojure.core/get map__1202 :user) port (clojure.core/get map__1202 :port) host (clojure.core/get map__1202 :host)] (let* [G__1203 (new Properties)] (. G__1203 put "mail.smtp.host" (let* [or__3943__auto__ host] (if or__3943__auto__ or__3943__auto__ "not.provided"))) (. G__1203 put "mail.smtp.port" (let* [or__3943__auto__ port] (if or__3943__auto__ or__3943__auto__ "25"))) (. G__1203 put "mail.smtp.auth" (if user "true" "false")) (if sender (do (let* [G__1204 G__1203] (. G__1204 put "mail.smtp.from" sender) G__1204))) (if user (do (let* [G__1205 G__1203] (. G__1205 put "mail.smtp.user" user) G__1205))) (if tls (do (let* [G__1206 G__1203] (. G__1206 put "mail.smtp.starttls.enable" "true") G__1206))) G__1203))))) I see this: defn make-props [sender {:keys [host port user tls]}] re-written as: (fn* ([sender p__1201] (let* [map__1202 p__1201 map__1202 (if (clojure.core/seq? map__1202) (. clojure.lang.PersistentHashMap create (clojure.core/seq map__1202)) map__1202) tls (clojure.core/get map__1202 :tls) user (clojure.core/get map__1202 :user) port (clojure.core/get map__1202 :port) host (clojure.core/get map__1202 :host)] So, if the destructuring is re-written by macroexpand, then I can reasonably assume that destructuring is implemented as a macro, yes? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
