Clojure Repl - Is there a way to see what variables have been defined (and are thus available) in a REPL session?

Question

If I've been playing around in a clojure REPL (might have been experimenting with (assoc) or (seq) or (reduce) and created some temporary maps for examples), but wanted to print a listing of variables defined in that session, is there a way to do this? Something like (println def) or something?

Answer 1

You can use (dir user) if you are in the user namespace. Or any other ns you are interested into. This shows you all the def-ed things. If it's not there (it usually gets useed automatically in the REPL, you can find it in clojure.repl/dir).

Answer 2

ns-interns can get you pretty close I think.

user=> (def x 1)
#'user/x
user=> (def y 2)
#'user/y
user=> (ns-interns *ns*)
{x #'user/x, y #'user/y}
