kpn-style

kpn shared style configs.

Add this line to your application's Gemfile:

group :test, :development do
  gem 'kpn-style'
end

Or, for a Ruby library, add this to your gemspec:

spec.add_development_dependency 'kpn-style'

And then run:

$ bundle install

Create a .rubocop.yml with the following directives:

inherit_gem:
  kpn-style:
    - ruby-2.1.yml

Or for Ruby 2.4:

inherit_gem:
  kpn-style:
    - ruby-2.4.yml

Or for Ruby 2.5:

inherit_gem:
  kpn-style:
    - ruby-2.5.yml

Or for Ruby 2.7:

inherit_gem:
  kpn-style:
    - ruby-2.7.yml

Or for Ruby 3.0:

inherit_gem:
  kpn-style:
    - ruby-3.0.yml

Now, run:

$ bundle exec rubocop

or

$ rake rubocop

You do not need to include rubocop directly in your application's dependencies. kpn-style will include a specific version of rubocop and rubocop-rspec that is shared across all projects.

Sometimes you need to override style rules. RuboCop have a nice inheritance hierachy so you can override the default settings. The hierachy is:

inherit_gem -> inherit_from -> local rules

For example:

inherit_gem:
  kpn-style:
    - ruby-2.7.yml

inherit_from: .rubocop_todo.yml

AllCops:
  Exclude:
    - exclude/file.rb

1. Update the ruby-2.X.yml file
2. Update the version parameter spec.version in the kpn_style.gemspec
3. Tag the release: git tag VERSION
4. Push changes: git push --tags
5. Update the release notes on GitHub.com
6. Build and publish:

gem build kpn_style.gemspec
gem push kpn-style-x.x.x.gem

To push gems to rubygems.org you can use a ~/.gem/credentials with the rubygems_api_key. You can find a small how to on the Profile edit page https://rubygems.org/profile/edit in the section API ACCESS.

A special thanks to https://github.com/percy/percy-style/ for the idea and template of this Gem.
