This is an extraction of the ‘auto_link` method from rails. The `auto_link` method was removed from Rails in version Rails 3.1. This gem is meant to bridge the gap for people migrating.
By default auto_link returns sanitized html_safe strings. This behaviour can be overridden by setting the :sanitize option to false (thus making it insecure if you don’t have the content under control).
require 'rails_autolink' 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>" auto_link("Visit http://www.loudthinking.com/ or e-mail [email protected]", :link => :urls) # => "Visit <a href=\"http://www.loudthinking.com/\">http://www.loudthinking.com/</a> # or e-mail [email protected]" auto_link("Visit http://www.loudthinking.com/ or e-mail [email protected]", :link => :email_addresses) # => "Visit http://www.loudthinking.com/ or e-mail <a href=\"mailto:[email protected]\">[email protected]</a>" auto_link("Go to http://www.rubyonrails.org <script>Malicious code!</script>") # => "Go to <a href=\"http://www.rubyonrails.org\">http://www.rubyonrails.org</a> " auto_link("Go to http://www.rubyonrails.org <script>alert('Script!')</script>", :sanitize => false) # => "Go to <a href=\"http://www.rubyonrails.org\">http://www.rubyonrails.org</a> <script>alert('Script!')</script>" post_body = "Welcome to my new blog at http://www.myblog.com/. Please e-mail me at [email protected]." 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>.
