Module: Authlogic::Regex

Defined in:
lib/authlogic/regex.rb

Overview

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

Constant Summary collapse

EMAIL =

A general email regular expression. It allows top level domains (TLD) to be from 2 - 24 in length. The decisions behind this regular expression were made by analyzing the list of top-level domains maintained by IANA and by reading this website: www.regular-expressions.info/email.html, which is an excellent resource for regular expressions.

/
  \A
  [A-Z0-9_.&%+\-']+   # mailbox
  @
  (?:[A-Z0-9\-]+\.)+  # subdomains
  (?:[A-Z]{2,25})     # TLD
  \z
/ix
EMAIL_NONASCII =

A draft regular expression for internationalized email addresses. Given that the standard may be in flux, this simply emulates @email_regex but rather than allowing specific characters for each part, it instead disallows the complement set of characters:

  • email_name_regex disallows: @[]^ !“#$()*,/:;<=>?‘{|}~\ and control characters

  • domain_head_regex disallows: _%+ and all characters in email_name_regex

  • domain_tld_regex disallows: 0123456789- and all characters in domain_head_regex

LOGIN =

A simple regular expression that only allows for letters, numbers, spaces, and .-_@+. Just a standard login / username regular expression.

/\A[a-zA-Z0-9_][a-zA-Z0-9\.+\-_@ ]+\z/
