Rails Ruby on Rails

This patch adds a url helper that allows you to create a link, adding the class "current" when in the current page.

I've found myself using this helper much more than link_to_unless_current. And because almost every site has some sort of tabbed navigation, I think it makes sense to push it to rails.

== Examples

Let's say you have a navigation menu...

<ul id="navbar">
  <li><%= link_to_tagged_current("Home", { :action => "index" }) %></li>
  <li><%= link_to_tagged_current("About Us", { :action => "about" }) %></li>
</ul>

If in the "about" action, it will render...

<ul id="navbar">
  <li><a href="/controller/index">Home</a></li>
  <li><a href="/controller/about" class="current">About Us</a></li>
</ul>

...but if in the "index" action, it will render:

<ul id="navbar">
  <li><a href="/controller/index" class="current">Home</a></li>
  <li><a href="/controller/about">About Us</a></li>
</ul>
