How do I pass a function as a parameter to in elisp?

I'm trying to pass one method to another in elisp, and then have that method execute it. Here is an example:

(defun t1 ()
  "t1")

(defun t2 ()
  "t1")

(defun call-t (t)
  ; how do I execute "t"?
  (t))

; How do I pass in method reference?
(call-t 't1)
Solution

  • First, I'm not sure that naming your function t is helping as 't' is used as the truth value in lisp.

    That said, the following code works for me:

    (defun test-func-1 ()  "test-func-1"
   (interactive "*")
   (insert-string "testing callers"))

(defun func-caller (callee)
  "Execute callee"
  (funcall callee))

(func-caller 'test-func-1)

    Please note the use of 'funcall', which triggers the actual function call.
