My first Ruby programming question :-)

#1

Dec 26th, 2007

Hello, I'm pleased to be here by way of the html forum. I've been using php for static pages for 18 months. I wanted to learn rails, but I just realized that I could configure my host to automate index.rhtml files just like php. This is a major motivator for me to learn Ruby, and after a few more months I can start fresh with Rails. OK, here is the code that works in PHP, and what I've got so far in Ruby. The JS effect can be viewed here: http://listenlight.net/13 ---

<?php

  $i = 0; $n = 0;
  
  $str = "listenlightpoetryjournal";
  
  while( $str[$i] != "" ) {
    echo("<span id=\"n".$n++."\" style=\"position:relative; visibility: hidden; font-size: normal; top:".(rand(-18, 18))."px; color: black;\">".$str[$i]."</span>");
  
    $i++;
  }

  
?>

  <%   
  def banner
      str = "listenlightpoetryjournal"
      i, n = 0, 0
    until c = str[i] == nil 
        line = "<span id=\"n", n, "\" style=\"position: relative; font-size: normal; top:", rand(36) - 18, "px;\">", c, "</span>"
        i += 1
        n += 1 
        output = output, line
    end
  end
   %>
   
   <%= banner  %>

In the Ruby example, I've set the visibility attribute in the CSS, attempting to clean the markup. Also, is there a way to do a parallel incrementing?--such as a, b += 1, 1 (?)
