How do I clear the screen in Ruby?

Question

I really need to know how to clear the screen in Ruby. I've already looked all over and haven't found anything that can help.

I've already tried using cls in several formats and it NEVER worked (I am on Windows, btw).

All that happens is an arrow keeps showing up in the IRB console.

Answer 1

To clear the terminal window on multiple operational systems, you could use:

def clear
  if Gem.win_platform?
    system 'cls'
  else
    system 'clear'
  end
end

Documentation for Gem#win_platform?
Is this a windows platform?

Answer 2

I found out earlier today that 'cls' doesn't work in RubyMine but it will work if I run the app in command prompt. It would've been nice if I had been told about that earlier.

Answer 3

在终端上键入“清除”，然后按Enter键，它将清除屏幕。
