… It’s called AutoHyperlinks. You may have heard of it, you may have not (but if you use Adium, you’ve used it). But that’s not important.

What is important, at this very moment, is that I’ve adapted it (and my former Coda Plugin) to a system-wide service for Snow Leopard.

This lets you turn any (editable) text, anywhere in the system, into a linkified string: RTFs get clickable link attributes, and plain text gets a HTML A tag.

The code is here: http://bitbucket.org/sholt/autolink-service/

The binary is here: http://bitbucket.org/sholt/autolink-service/downloads/AutoLink.service.zip

Just drop it into Library/Services and go.
