Instance Method Details

#format(path, text) ⇒ Object

This abuses the –stdin option of rubocop and reads the formatted text from the options that rubocop mutates. This depends on parallel: false as well as the fact that rubocop doesn’t otherwise dup or reassign that options object. Risky business!

Reassigning options is done here:

https://github.com/rubocop/rubocop/blob/master/lib/rubocop/cop/team.rb#L131

Printing options

https://github.com/rubocop/rubocop/blob/master/lib/rubocop/cli/command/execute_runner.rb#L95

Setting ‘parallel: true` would break this here:

https://github.com/rubocop/rubocop/blob/master/lib/rubocop/runner.rb#L72
