Add RuboCop?

[vzvu3k6k]

Problems to solve

This project doesn't have a coding style guideline or linters. This causes two problems:

• It is too cumbersome to manually find simple coding style issues (for both contributors and reviewers).
• Different tastes in coding styles between contributors can lead to inconsistencies and confuse new contributors.

Possible solutions

• Add RuboCop to this project (and check code in CI?)

Possible risks

• The default RuboCop rules might be too strict or controversial?
  • Starting from the minimum rules will be better.

@vbrazo I've created an issue for now. Please feel free to rewrite the description.

@vbrazo I have implemented RuboCop in my local Ruby repository. I found some issues. Here is the report of the RuboCop: 90 files inspected, 498 offenses detected, 255 offenses auto-correctable.
Shall I go ahead and implement this for the remote repository or tweak it to make it a little simple?

@msaf9 what .rubocop.yml are we proposing? Could you please post here so we could take a look?
