New to Ruby

Ok, I have never used Ruby before and I'm trying to figure out how to convert my following Perl code into Ruby to do exactly what is does now.

Basically I used a loop structure to produces the following output (user can specify how many lines need to be printed):

A
AA
AAA
AAAB
AAABA
AAABAA
AAABAAA
AAABAAAB

#!/usr/bin/perl

print "Please enter your name: ";

$name = <STDIN>;

print "Please enter your favorite number: ";

$f = <STDIN>;
$a = 0;

if ($f < 0)
{
 while ($f <0)
 {
 print "Please enter a positive number: ";
 $f =<STDIN>;
 } 
}

{
 while ($a < $f)
 {
 print $name;
 $b = $a + 1;
 $a = $b;
 }
}

Your text example doesn't really show how the script you provide works. Here's what you are probably after though - this could be a bit more robust but in this state it's clear:

#!/usr/bin/env/ruby

#first get the name
puts "Enter your name"
name =  gets
#now get a number, to_i returns the entered string (eg "5" to an integer eg 5)
puts "Enter a number"
number = gets.to_i

#times is a method on integer, we can use it to iterate through the block
number.times do 
  #print the name
  puts name
end

use gets.chomp to remove any trailing after space from the input

I also used this link to start ruby - seems to be helping awesomely for beginners.

I'm not sure if your referring to ruby or ruby on rails. Anyways great tutorials for Ruby on rails are guides.rubyonrails.org and awesome videos with explanations would be http://railscasts.com
