Question

How can I get clojure "def" for revaluation without using: reload?

Answer 1

(def x 0)
x   ; => 0
(def x 1)
x   ; => 1

You cannot override var from another namespace, so you need to switch to that namespace with in-ns before defing again.

Answer 2

You can also call load or load-file in repl.

(load-file "foo/bar.clj")
(load "foo/bar")
