How should I do clear screen on ocaml toplevel?

Question

I am using ocaml toplevel with ledit (ledit -l 100 ocaml) on Ubuntu 14.04. Since there is no way to do clear screen, all the time, I keep dwelling at the bottom of the screen.

I would like to know if there is a way to do clear screen at toplevel?

Thanks in advance.

Regards.

Have you already tried [utop](https://github.com/diml/utop)? — Shamaoke, Dec 24 '14 at 04:01
@Shamaoke No I have not, I like the minimalist approach of the original toplevel and libraries. — Str., Dec 24 '14 at 17:15

Sys.command "clear" is quite functional - it clears and returns an int :-)

My favourite is Ctrl+l - unixoides only.

You could try:

# Sys.command "clear";;

However, it is normal to dwell at the bottom of the screen. The command line has worked this way for at least 30 years :-)

You can try: let clear = function x -> Sys.command("clear")+x;;

Then everytime you call: clear x;; where x is an int your screen should be clean again.
