Suppose I have a clojure file called "app.clj" that contains something
like:
(ns app)
(defn foo [] (println "hello"))
(defn reader [filename] (load-file filename))
and a file called "data" that simply contains
(foo)
What I would like to see, from the REPL, is:
user=> (load-file "app.clj")
user=> (app/reader "data")
hello
As described, this doesn't work. load-file looks up symbols in the
current namespace ("user" in this case), but foo is interned in app.
I found that I could get the behavior I wanted if I changed the
definition of reader to:
(defn reader [filename] (binding [*ns* (the-ns 'app)] (load-file
filename)))
But this has a sort of evil feeling to it. Is there a better way of
doing this?
Thanks,
Paul
P.S. I know that doing (load-file "app.clj") (in-ns 'app) (reader
"data") from the REPL works as well, but I don't want to force the
user to switch namespaces.
