Rentacop

A more relaxed default set of RuboCop rules.

Install

Run:

$ gem install rentacop

Or, add this line to your Gemfile:

group :test, :development do
  gem 'rentacop'
end

Prerequisites

We assume you have rubocop installed either globally:

$ gem install rubocop

or in your bundle

$ bundle add rubocop --group development,test

Usage

This gem contains two rule sets:

  1. Global rubocop rules in rentacop.yml
  2. RSpec rubocop rules in rspec.yml

Configuring .rubocop.yml

If you are not using RSpec, add the following to the top of your .rubocop.yml:

inherit_gem:
  rentacop: rentacop.yml

If you are using rubocop-rspec, and wish to include the RSpec rules from this repository, add this instead:

require: rubocop-rspec

inherit_gem:
  rentatop:
    - rentacop.yml
    - rspec.yml

This .rubocop.yml contains our full recommended configuration:

# .rubocop.yml
require:
  - rubocop-performance
  - rubocop-rspec

inherit_gem:
  rentacop:
    - rentacop.yml
    - rspec.yml

inherit_mode:
  merge:
    - Exclude
    - Include

  TargetRubyVersion: 3.0

Running rubocop

After creating your .rubocop.yml file, run:

$ rubocop
# or, if you do not have rubocop installed globally
$ bundle exec rubocop

To create a todo list, run:

$ rubocop --regenerate-todo
