- # Turns all URLs and e-mail addresses into clickable links. The <tt>:link</tt> option
- # will limit what should be linked. You can add HTML attributes to the links using
- # <tt>:html</tt>. Possible values for <tt>:link</tt> are <tt>:all</tt> (default),
- # <tt>:email_addresses</tt>, and <tt>:urls</tt>. If a block is given, each URL and
- # e-mail address is yielded and the result is used as the link text. By default the
- # text given is sanitized, you can override this behaviour setting the
- # <tt>:sanitize</tt> option to false.

- # ==== Examples
- # auto_link("Go to http://www.rubyonrails.org and say hello to david@loudthinking.com")
- # # => "Go to <a href=\"http://www.rubyonrails.org\">http://www.rubyonrails.org</a> and
- # # say hello to <a href=\"mailto:david@loudthinking.com\">david@loudthinking.com</a>"
- #
- # auto_link("Visit http://www.loudthinking.com/ or e-mail david@loudthinking.com", :link => :urls)
- # # => "Visit <a href=\"http://www.loudthinking.com/\">http://www.loudthinking.com/</a>
- # # or e-mail david@loudthinking.com"
- #
- # auto_link("Visit http://www.loudthinking.com/ or e-mail david@loudthinking.com", :link => :email_addresses)
- # # => "Visit http://www.loudthinking.com/ or e-mail <a href=\"mailto:david@loudthinking.com\">david@loudthinking.com</a>"
- #
- # post_body = "Welcome to my new blog at http://www.myblog.com/. Please e-mail me at me@email.com."
- # auto_link(post_body, :html => { :target => '_blank' }) do |text|
- # truncate(text, :length => 15)
- # end
- # # => "Welcome to my new blog at <a href=\"http://www.myblog.com/\" target=\"_blank\">http://www.m...</a>.
- # Please e-mail me at <a href=\"mailto:me@email.com\">me@email.com</a>."

- #
- # You can still use <tt>auto_link</tt> with the old API that accepts the
- # +link+ as its optional second parameter and the +html_options+ hash
- # as its optional third parameter:
- # post_body = "Welcome to my new blog at http://www.myblog.com/. Please e-mail me at me@email.com."
- # auto_link(post_body, :urls)
- # # => "Welcome to my new blog at <a href=\"http://www.myblog.com/\">http://www.myblog.com</a>.
- # Please e-mail me at me@email.com."
- #
- # auto_link(post_body, :all, :target => "_blank")
- # # => "Welcome to my new blog at <a href=\"http://www.myblog.com/\" target=\"_blank\">http://www.myblog.com</a>.
- # Please e-mail me at <a href=\"mailto:me@email.com\">me@email.com</a>."
