I was working up a form and needed to come up with an email regex. I know by now I probably should have my own regex library, or even be able to write my own - but I haven’t exercised my regex skills enough. Often time doesn’t allow an extensive learning period when your already half way through creating a form!

I came across this great regex library at regexlib.com. It’s searchable, offers on the fly tests of user contibuted regular expresssions, rss feeds of recently added patterns, and contains a Cheat Sheet for regex reference.

Of course, programmer beware. Be careful copying and pasting code. And definately test that code before you implement it.

   If you find the expression you need the great but good luck. Unless you are doing something common more than likely you should just write your own. Just sayin;)

   Thanks for popping by Jimbo. I agree - but sometimes time doesn’t allow me to properly learn and code one up right away. So grabbing a quick email validation regex can temporarily get me by
