Squashing that particular bug wasn’t too hard, but I wanted to take the functionality a step further (closer to the calibre of Gmail) and it turns out, writing robust auto-linking code is more difficult than it initially seems. So I played with it a little at a time here and there, testing as many edge cases as I could think of. The result is a function that’s more robust than most URL auto-linking code I’ve come across.

I still need to add support of internationalized TLDs and HTML. So, although it only works with plain text for now, I think it’s off to a good start. Check out the demo or download the source.
