Public Class methods

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.

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.
