ActionView::Helpers::TextHelper
auto_link(text, link = :all, href_options = {}, &block)public
Turns all urls and email addresses into clickable links. The link parameter will limit what should be linked. You can add html attributes to the links using href_options. Options for link are :all (default), :email_addresses, and :urls.
auto_link("Go to http://www.rubyonrails.org and say hello to [email protected]") => Go to <a href="http://www.rubyonrails.org">http://www.rubyonrails.org</a> and say hello to <a href="mailto:[email protected]">[email protected]</a>
If a block is given, each url and email address is yielded and the result is used as the link text.
auto_link(post.body, :all, :target => '_blank') do |text| truncate(text, 15) end

Documentation bug
When adding the :target option, the documentation states that you should user :href_options like so:
auto_link(post_body, :href_options => { :target => '_blank' })
However, I could only get it to work using :html instead:
auto_link(post_body, :html => { :target => '_blank' })
I'm using Rails 2.2.2, but I believe that this also happens for more recent version .
