Indeed my Ruby / Rails editor of choice for the moment is definitely NetBeans as it’s the one my productivity will increase the most with, and it is free. The development team is also really reactive, and the roots of the plugin seem serious and robust. You should notice that by default, it is packaged with JRuby interpreter and embedded Rails. That result in larger time than Idea or NetBeans when using rails generators. You should change those settings in Tools / Options / Miscellaneous / Ruby Application (as it seems to be working) to point your native Ruby interpreter (ie /usr/bin/ruby). That should accelerate each call to ruby (when you use generators for examples) which take much time when calling through JRuby. Unfortunately I didn’t find it myself that much fast, and I was losing the Output with hyperlinks of file created then.
