Base Rubocop settings for all Boxt Ruby projects.

Installation

Add this line to your application's Gemfile:

  # ...
  gem "boxt_rubocop"
end

And then execute:

bundle

Usage

Put this into your .rubocop.yml.

require:

To enable additional configuration for rubocop-rails and rubocop-rspec, add the following to your .rubocop.yml:

inherit_gem:
  boxt_rubocop:
    - rails.yml # use Rails cops - see Additional Extensions/Cops
    - rspec.yml # use rspec cops - see Additional Extensions/Cops

Creating new custom cops

Use the rake task new_cop to generate a cop template:

$ bundle exec rake 'new_cop[Boxt/Name]'
[create] lib/rubocop/cop/boxt/name.rb
[create] spec/rubocop/cop/boxt/name_spec.rb
[modify] lib/rubocop/cop/boxt_cops.rb - `require_relative 'boxt/name'` was injected.
[modify] A configuration for the cop is added into config/default.yml.

Documentation on creating a new cop can be found here.

NewCops is enabled by default.
