This gem allows you to combine multiple linters with their configs in one place and run all checks by one command with tabled-view summary report (see below). You should specify which linters you would like to use, for example rubocop, reek, scss_linter etc. Gem would load them if they are not installed and run checks.

One gem for rule them all:)

It works for 2.2.3, 2.3.1, 2.3.3 versions of Ruby MRI.

Add this line to your application's Gemfile:

gem 'supercop'

And then execute:

$ bundle

Or install it yourself as:

$ gem install supercop

Add supercop tasks to the Rakefile:

  spec = Gem::Specification.find_by_name 'supercop'
  load "#{spec.gem_dir}/lib/tasks/manage_settings.rake"
  load "#{spec.gem_dir}/lib/tasks/check.rake"

After install, you should modify supercop.yml and specify prefered linters. After that run

$ rake supercop:generate_config

for non-rails project (like gem) or

$ rails g supercop:config

for rails project

After that, please modify your supercop.yml config file, adding linters you want to use and run

$ rake supercop:load_dependencies

or you can do it manually by adding gems to your Gemfile (for other gems - to the end of file) and running bundle install.

Note: You should do it once.

Now you can run checks.

If you want to restore all affected files and clean up supercop remnants, please run

$ rake supercop:cleanup

This will delete config file and erase changes made by Supercop to your Gemfile and bundle.

$ rake supercop:check

'none' - means linter did not work correctly. To figured out why - change 'verbose' option to true
