I've tried the same, but not in core.clj, but in another file named hello.clj:
(ns kenji.hello )
(defn hi [name]
(println "HI " name))
Then I go to the REPL and I try:
[...@slicingupeyeballs:~/kenji]$ lein repl (12-29 23:26)
REPL started; server listening on localhost:21669.
kenji.core=> (:require 'kenji.hello)
nil
kenji.core=> (hi "nick")
java.lang.Exception: Unable to resolve symbol: hi in this context
(NO_SOURCE_FILE:2)
[...@slicingupeyeballs:~/kenji]$ ls -l src/kenji (12-29 23:31)
total 24
-rw-r--r--@ 1 ngw staff 244 Dec 29 16:24 core.clj
-rw-r--r--@ 1 ngw staff 5756 Dec 29 23:26 hello.clj
Stuff in core.clj works normally, no problem at all.
TIA,
ngw
