TD Critic

Critic
-- One who forms and expresses judgments of the merits, faults, value, or truth of a matter.

TD Critic is a gem that specializes in judging your coding style.

Add this to your application's Gemfile:

gem 'td_critic'

If you want to make sure that your project's build won't be broken accidentally by rubocop update, lock rubocop to certain version:

gem 'rubocop', '0.58.2'
gem 'rubocop-rspec', '1.28.0'

That is important especially for GEMs, where Gemfile.lock isn't committed to the repository.

Add the following line to your rubocop config

inherit_gem:
  td_critic: rubocop.yml

You can use the rubocop rake task to run rubocop on only the recently changed files (by Yury Lebedev)

bundle exec rake rubocop
