Rubular – Cool (but Scary) Website for Regular Expression Cowards

If you live in fear of regular expressions, as I do, I’m afraid there is no cure.  However, there is some help.  Rubular lets you check your regex’s as you construct them and has a handy reference guide as well so definitely check it out if you need to use this strong magic in your applications.

However, if “\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z” starts to make sense to you, you should lay off the hallucinogenic drugs and seek help immediately.
