How can I wrap operators with spaces

I would like to apply https://github.com/styleguide/ruby. But I do not manage to find out how I can wrap operators with spaces.

In other languages (e.g. Javascript), there is a "Spaces" Tab in Editor>Code Style but not for ruby.

Is there a simple way to achieve this? Is there even a configuration file which I could import to implement https://github.com/styleguide/ruby.
