module Authlogic
# This is a module the contains regular expressions used throughout Authlogic. The point of extracting
# them out into their own module is to make them easily available to you for other uses. Ex:
#
# validates_format_of :my_email_field, :with => Authlogic::Regex.email
module Regex
# A general email regular expression. It allows top level domains (TLD) to be from 2 - 4 in length, any
# TLD longer than that must be manually specified. The decisions behind this regular expression were made
# by reading this website: http://www.regular-expressions.info/email.html, which is an excellent resource
# for regular expressions.
def self.email
return @email_regex if @email_regex
email_name_regex = '[A-Z0-9_\.%\+\-\']+'
domain_head_regex = '(?:[A-Z0-9\-]+\.)+'
domain_tld_regex = '(?:[A-Z]{2,4}|museum|travel)'
@email_regex = /\A#{email_name_regex}@#{domain_head_regex}#{domain_tld_regex}\z/i
end
# A simple regular expression that only allows for letters, numbers, spaces, and .-_@. Just a standard login / username
# regular expression.
