RubyMine and Radiant apps?

Hello Jens-Christian,

We are working on a Radiant project where we are writing a bunch of extensions. I know that the JetBrains people are active in Radiant development (Russian translation). I'm assuming that RubyMine can handle Radiant projects just fine, but needs some the specific setup.

I am looking for a way to run specs in radiant extensions directly from the IDE - any hints on how to set this up?

What kind of extensions do you mean?
In order to run specs you should attach rspec and rspec-rails gems to your project in File | Settings | Ruby SDK and Gems | Attach Gems.
Once this is done you can run single spec testcase or file or all the specs in folder.

Regards,
Oleg
