Hello

Im new to ruby and programming and I saw a guy do this on a tutorial  
video:

“Hello”.each\_char do |x|  
puts x  
end

The result was that it printed one letter in the string at a time until  
it had printed the whole word “Hello” in a vertical line. My problem is  
that this wont work when I try it and I’ve done exactly like he did it.  
The only thing I can think of is that maybe I have another version of  
ruby than he has, but perhaps anyone of you knows the answer?

what version of ruby are you running? It works for me on 1.9.1 on  
windows. Try this:

> “Hello”.each\_byte { |x| puts x.chr }

I think the 1.8x version of Ruby’s string implementation is in another  
module: jcode. I believe you can run your original code, you just have  
to require ‘jcode’.

I don’t know why they haven’t packaged a more up-to-date one-click  
installer. They do have the 1.9.1 version pre-built for windows. I’m  
running it and it works great.

Because it’s a lot of work 🙂

Thanks, the example you made works (alto I didnt fully understand it).

Im about 95% sure that I am running ruby 1.8.6 since I just used the  
one-click installer that’s on [ruby-lang.org](http://ruby-lang.org). Why dont they have a  
one-click installer for the latest version of ruby? XD

As I understand it, there will be no more ‘one-click’ installers. The  
new ‘official’ windows installer is [http://rubyinstaller.org/](http://rubyinstaller.org/) which does  
indeed have Ruby 1.9.1. A word to the wise, I’d suggest uninstalling  
the old one-click, before installing the new rubyinstaller to avoid any  
path confusions.
