It is a library that checks whether the written code complies with the coding standards. Rubocop is famous as a parsing tool, but since there are various settings, this time we will introduce rubocop-airbnb customized for the development site.
group :development, :test do gem 'rubocop-airbnb' end
$ bundle install
Create new .rubocop.yml and .rubocop_airbnb.yml in the same directory as the Gemfile.
inherit_from: - .rubocop_airbnb.yml AllCops: Exclude: - 'bin/*' - 'config/**/*' - 'db/**/*' - 'spec/spec_helper.rb'
require: - rubocop-airbnb
If you get an error when calling, please be careful because you may have forgotten to add "." Or "_" in this file or you may have made a typo.
$ rubocop --require rubocop-airbnb
$ rubocop --require rubocop-airbnb -a
It will be harder to fix later, so please try to introduce it before you start writing code.
