RuboCop::Packaging

RuboCop::Packaging is an extension of RuboCop, which is a Ruby static code analyzer (a.k.a. linter) and code formatter.

It helps enforcing some of the guidelines that are expected of upstream maintainers so that the downstream can build their packages in a clean environment without any problems.

Documentation

A detailed documentation, explaining what this extension is doing and the reasoning behind it, can be found here: https://docs.rubocop.org/rubocop-packaging/

We also have a packaging-style-guide, listing some good and bad examples and the rationale behind these cops.

In case anything is not clear, please feel free to raise an issue, asking for more explanation!

Installation

Add this line to your application's Gemfile:

gem 'rubocop-packaging'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install rubocop-packaging

Usage

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

RuboCop configuration file

Put this into your .rubocop.yml file:

require: rubocop-packaging

Alternatively, use the following array notation when specifying multiple extensions:

require:
  - rubocop-other-extension
  - rubocop-packaging

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

Command line

rubocop --require rubocop-packaging

Rake task

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

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.
