Someone asked on the #ruby-lang IRC channel earlier today whether there's a utility somewhere for extracting URLs from a string. Since I only have a gazillion things I should've been doing, I decided to hack together some Ruby...

So, here's UrlRegex and a test for it.

If and when you find a flaw in the code, post a comment and I'll see if I can get myself to fix it ;)

UPDATE: I wasn't aware rafb.net's "paste" application loses old pastes that quickly. I've now uploaded the source code on this server.
