Testing Clojure main from REPL
I have defined a -main
function in a :gen-class :main true
namespace in Clojure. I am trying to test it from the REPL.
My main开发者_开发技巧
function looks like this:
(defn -main [& args]
; ...
)
and I am trying to call it with (ns/-main "-x" "foo")
, (ns/-main "-x foo")
, (ns/-main ["-x" "foo"])
, (ns/-main (into-array String ["-x" "foo"])
, etc., and all give me various errors.
How do I call this function from the REPL and pass in some command line arguments to test it?
Thanks.
I tried to reproduce it:
(defn -main [& args]
(apply str args)
)
Then called like:
(-main "a" "b" "c")
And it evaluated to:
"abc"
As it should..
Be sure to check are you using the right namespace identifier, also see if anything weird is happening inside your -main
function, like using a string as a number..
Also, it wouldn't hurt to see your error message on this..
