The goal of rubocop-facter is to extend RuboCop to support Facter-specific checks. There are various "gotchas" that apply to Facter specifically, and not general Ruby programming.

Add this line to your application's Gemfile:

gem 'rubocop-facter'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rubocop-facter

Add the following to your Puppet module's .rubocop.yml file:

require:
  - rubocop-facter

General RuboCop installation and usage instructions can be found in the RuboCop README.
