Clojure is a Lisp, so it should be possible to extend it yourself ...
What about something like this?
(defmacro locally-using
"Allows to use symbols from other namespace in the local scope
of the macro body.
Syntax: (locally-using [<symbol>*] :from <namespace>
<body>)"
[symbols from ns-name & body]
(assert (= from :from) "Wrong syntax ... delimiter :from missing or
misplaced!")
(let [local-vars (map (fn [sym] (symbol (str ns-name) (str sym)))
symbols)]
`(do (require '~ns-name)
(symbol-macrolet [~@(interleave symbols local-vars)]
~@body))))
which then let's you write:
(locally-using [split] :from clojure.string (split "Hello world" #"
"))
The above macro could probably be made smarter to only require the lib
if it not already loaded and also "unload" when it is done in this
case. But since you have to load the lib anyways to use it and
qualified names do not clutter your current namespace, the above
version seems to be good enough.
Cheers,
Nils
