JetBrain’s is offering a 50% off coupon for their new Ruby editor, RubyMine. But you have to sign up for the coupon now and they’ll email you a coupon code that you can use when the product is released. Worth signing up for if you’re even the tiniest bit interested in purchasing the release version. They announced that the IDE will run $99 once they go live.
I’ve been running a beta version for a few weeks now and am becoming a big fan. Having key mappings that match Resharper really make the transition back and forth from .Net to Ruby a little less painful.
If you’re interested in following the tool as it progresses, you may want to follow rubymine on twitter.
