Ruby $stdin.gets without showing chars on screen

Question

I want to ask users to type in a password, but i dont want the chars to appear on screen as they type.

How do I do this in Ruby?

Answer 1

There is a gem for such user interaction: highline.

password = ask("Password:  ") { |q| q.echo = false }

Or even:

password = ask("Password:  ") { |q| q.echo = "*" }
