This gem/plugin is a re-packaged and gem’ified version of the original plugin with credit as follows:
Ximon Eighteen <[email protected]> Dan Kubb <[email protected]> Thijs van der Vossen <[email protected]>
This Ruby on Rails plugin implements an ActiveRecord validation helper called validates_as_email. The helper acts as if validates_format_of was used with a regular expression that defines an RFC822 email address conformance test.
The plugin implements the regular expression here:
http://tfletcher.com/lib/rfc822.rb
Which is an implementation in Ruby of a regular expression published by Cal Henderson for PHP here:
http://www.iamcal.com/publish/articles/php/parsing_email
