Hi!
I would like to write macro, which tries to evalute one of statements.
If exception happens the next statement is taken, if not then rest of
expressions execution is stopped.
(defmacro try-this[ & body ]
`(if (seq ~body)
(try
~(first body)
(catch Exception e# (try-this ~(rest body))))
(throw (Exception. "nothing succeed"))))
(try-this
(/ 2 0)
(+ 2 3)
(println "2"))
So the macro should expand to something like this:
(try
(/ 2 0)
(catch Exception e
(try (+ 2 3)
(catch Exception e
(try (println "2")
(catch Exception e (Exception.
"nothing succeed")))))))
Any help?
