Can I clean the repl?

Question

I have played with a lot of code in a repl console, how can I clear it? I would like a fresh one without restarting it. Can that be done?

Answer 1

It depends what you mean by 'clean'. To remove all namespaces within a 'package' you can use:

(mapv remove-ns 
  (map symbol 
    (filter #(.startsWith % "org.mycompany") 
      (map str (all-ns)))))

Answer 2

In EMACS/slime REPLs C-c C-o clears the last output (in case you've typed something that gave a very long answer) C-c M-o clears the whole thing

In GNOME terminals, you've got a menu option Terminal/Reset and Clear
