Stupid Ruby Tricks

[Chris Carter]

Hey guys,
To try out this "post blog articles to the list, maybe insight some
discussion" idea, I offer the community this. I maintain the "Stupid
Ruby Tricks" wiki over at http://sn.oplo.ws and I recently compiled a
bit of a "best of". Check it!

Firstly, I appologize if this question has already been answered but I =
could not figure out the=20
correct way to word my search on google to find anything relevant. I am =
running Ruby 1.8.2-15
on windows XP. I used the one-click version.
I am trying to write a script that will prompt a user for a password and =
not echo the characters back to screen.
Is this possible in the dos command window? If so then please give me a =
reference else is there an alternative
such as using TK?

thank you,
raymond

page 791 and 792 of the ruby cookbook covers this.

require 'rubygems'
require 'highline/import'

def get_password(prompt='Password: ')
ask(prompt) { |q| q.echo = false}
end

get_password("What's your password?")

Or just:

require "rubygems"
require "highline/import"

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

__END__

I don't believe this is for windows, but there's a library for it here:
