How to animate input line?

Question

ruby

In general, I want to make a line animation so that during the input by a person (gets) in place of the letter "the wand is spinning"
The cycle for turning the wand is here:

def ss
  while true
    print "|\r"
    sleep 0.2
    print "/\r"
    sleep 0.2
    print "-\r"
    sleep 0.2
    print "\\\r"
    sleep 0.2	
  end
end

And here's how to connect it with writing a line - it's not clear ... I
tried through streams, but nothing happened.
a = Thread.new { ss }
Can someone tell me?

Answer 1

Can it be like this

def spinner
  chars = %w{ | / - \\ }
  thread = Thread.new { yield }
  while thread.alive?
    $stdout.print chars[0]
    sleep 0.5
    $stdout.print "\b"
    chars.push chars.shift
  end
  thread.join
end

Call for example like this:

spinner do
  name=gets
  puts name
end

But in place of the entered characters, there will most likely be dashes.

If you want the wand to spin at the same time and you can enter text, then this is very unlikely.
If you just animate something:
