Re^3: regexp to only allow for formally valid email addresses

[hangon]

Unless you don't think the character classes are a bit redundant. I assume fraktalisman only wants to match \w as well as '-' and '.' since its for e-mail addresses.

# my guess is that he's not trying to do this
  =~ /^[.]+@[.]+$/

# either of these make more sense for matching an e-mail address
  =~ /^[a-zA-Z_\-\.0-9]+@[a-zA-Z_\-\.0-9]+$/
  =~ /^[\w\-\.]+@[\w\-\.]+$/

Or am I missing something painfully obvious?

The dot is not special within square brackets. /[.]/ only matches ".", not "a".
