Installation

Just install the rubocop-chef gem

chef gem install rubocop-chef

Usage

You need to tell RuboCop to load the Chef extension. There are three ways to do this:

RuboCop configuration file

Put this into your .rubocop.yml.

require: rubocop-chef

Now you can run rubocop and it will automatically load the RuboCop Chef cops together with the standard cops.

Command line

rubocop --require rubocop-chef

Rake task

RuboCop::RakeTask.new do |task|
  task.requires << 'rubocop-chef'
end

The Cops

All cops are located under lib/rubocop/cop/chef, and contain examples/documentation.

In your .rubocop.yml, you may treat the Chef cops just like any other cop. For example:

Chef/AttributeKeys:
  Exclude:
    - libraries/my_vendored_file.rb
