Ruby - Passing Blocks To Methods
- by Chris Bunch
I'm trying to do Ruby password input with the Highline gem and since I have the user input the password twice, I'd like to eliminate the duplication on the blocks I'm passing in. For example, a simple version of what I'm doing right now is:
new_pass = ask("Enter your new password: ") { |prompt| prompt.echo = false }
verify_pass = ask("Enter again to verify: ") { |prompt| prompt.echo = false }
And what I'd like to change it to is something like this:
foo = Proc.new { |prompt| prompt.echo = false }
new_pass = ask("Enter your new password: ") foo
verify_pass = ask("Enter again to verify: ") foo
Which unfortunately doesn't work. What's the correct way to do this?
