Hi ppl,
Above I wrote a macro with-open-flexi! ... which I'm planning to use
in my app's API . .. please let me know if there are any bugs /
gotchas / improvements etc...
I didn't get any responses, so does it means there is something so
obviously wrong that you can't even begin where to start :) (I doubt
so) or does it looks OK ..?
(See the above post for detailed comments & usage)
(defmacro with-open-flexi!
[bindings & body]
(if (= 0 (count bindings))
`(do ~...@body)
(let [[o i c & more] bindings]
`(let [~o ~i]
(try
(with-open-flexi! [...@more] ~...@body)
(finally ~c))))))
- Thanks
