title: Ruby: Console-based menu
body: <p>I have an array of Names and URLs and would like to present the user with a list of the names in form of an up-/down-scrollable menu. Basically what <code>dialog</code> allows within the shell.</p>
  
  <p>I have looked into <code>ncurses-ruby</code>, <code>rdialog</code> and <code>HighLine</code> but they all seem to be either abandoned as a project or throw errors even from their examples (if at all existent).</p>
  
  <p>Could someone kindly point me to either a nice, usable gem that does TUI menus <em>or</em> a simple (I'll be new to this then...) introduction on how to to this in Rails (ie. presentation of available data (=what I have in my array)) and how to handle the user's choice?</p>
  
  <p>Thank you!</p>
