Programmatically evaluate a list of functions in Clojure

Question

I am trying figure out how to programmatically evaluate a list of functions.

Lets say that I have this code:

(defn foo
  []
  (println "foo"))

(defn bar
  []
  (println "bar"))

(def funcs [foo bar] )

I want execute all functions of funcs in a programmatically way.

I am tried use eval, but no succcess.

Thanks for any help.

Answer 1

Use for if you want the return values, and are OK with lazy evaluation (your functions are not guaranteed to be called until you access the return value), and doseq if you don't need the values and are doing this for immediate side effects.

(doseq [f [foo bar]]
  (f))

(def fs
  (for [f [foo bar]]
    (f)))

Answer 2

You can use juxt:

((apply juxt funcs))
