If you have installed Rubocop Show archive.org snapshot in your project, RubyMine can show you Rubocop violations immediately in your editor. You probably already know this feature.
Example
Enable/Disable marking
If your RubyMine does not show you any violations, although there are some, you may have to enable the setting first.
To do so, open Navigate -> Search Everywhere -> Actions (Or use the shortcut CTRL + SHIFT + A) and type in "rubocop", then you should see something like this:
Set Gems and Gem management:Rubocop to ON if you want to see Rubocop marking in your Editor or switch it to OFF if you want to hide it.
