Ruby Screenshot of the Week #34: Detecting Duplicates Hash Keys

You didn't think we had forgotten Ruby, did you? Here's a new Ruby editor feature: Detecting duplicate hashkeys. As "Fjan" (who filed the request) says, when some Rails calls allow dozens or more keys, you can accidentally add a hash key twice, with subtle results. NetBeans now tracks these down and points them out for you. This is going into 7.0, but you can use this 6.5-compatible module as well. Martin and Erno have also been hard at work. There are many new features in 6.5 (which I'll cover when 6.5 ships in a week or two). But in the 7.0 trunk, the debugger can attach to arbitrary and remote processes - see Martin's blog entry for more info. And Erno has added support for Shoulda testing and more test runner improvements - details here.
