Calling a Function From a String With the Function’s Name in Clojure

Question

How could I call a function with a string? e.g. something like this:

(call "zero?" 1) ;=> false 

Answer 1

Something like:

(defn call [^String nm & args]     (when-let [fun (ns-resolve *ns* (symbol nm))]         (apply fun args))) 

Answer 2

A simple answer:

(defn call [this & that]   (apply (resolve (symbol this)) that))  (call "zero?" 1)  ;=> false 

Just for fun:

(defn call [this & that]   (cond     (string? this) (apply (resolve (symbol this)) that)    (fn? this)     (apply this that)    :else          (conj that this)))  (call "+" 1 2 3) ;=> 6 (call + 1 2 3)   ;=> 6 (call 1 2 3)     ;=> (1 2 3)
