Hi,
I am learning clojure these days, but on .Net. I have the following
code -
(import '(System.IO Path Directory File DirectoryNotFoundException))
(defn starts-with-hmorx [name]
(if (or (= (.ToUpper (.ToString name)) "H")
(= (.ToUpper (.ToString name)) "M")
(= (.ToUpper (.ToString name)) "X")) true false))
(defn GetSubfolderName [filename]
((def name-wo-extn (Path/GetFileNameWithoutExtension filename))
(def first-char (aget (.ToCharArray (.ToString name-wo-extn)) 0))
(if (Char/IsDigit first-char) (Convert/ToInt32 first-char) (if
(starts-with-hmorx first-char) (.ToLower (.ToString first-char))
"other"))))
But when I call (GetSubfolderName "D:\\CsEx\\Manoj.cs"), I get this
exception -
System.InvalidCastException: Unable to cast object of type
'System.String' to type 'clojure.lang.IDeref'.
at lambda_method(Closure , Object )
at AFunction_impl.invoke(Object )
at lambda_method(Closure , Object )
at AFunction_impl.invoke(Object )
at lambda_method(Closure )
at AFunction_impl.invoke()
at REPLCall(Closure )
Any help is greatly appreciated.
Thanks,
Manoj.
