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 ---
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 (?)
<?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 (?)

Re: My first Ruby programming question :-) My solution ---
No more PHP for this one.
<%=
def banner
i, n, span, str = 0, 0, String.new, "listenlightpoetryjournal"
until i == str.length do
span << "<span id=\"n" << n.to_s << "\" style=\"top: "
<< (rand(36) - 18).to_s << "px;\">" << str[i] << "</span>"
i, n = i + 1, n + 1
end
return span
end
banner
%>No more PHP for this one.

Although your solution is fine it can be a little more readable (and re-usable) in rails.
In the controller:
ruby Syntax (Toggle Plain Text)
Then in the view
<%= banner("listenlightpoetryjournal") %> Note to self... pocket cup

The only nit I have with it is that I wouldn't put the
banner method in the controller, since it has nothing to do with the "traffic cop" jobs that controllers normally do. I would put it in a helper file, either this controller's helper file or the application_helper.rb file (if it's a method you'd want to use in other controllers).Ed
