Rubocop Config Updater

Rubocop requires a lot of changes to its config if you didn't update it for a long time. That's why I wrote this gem, because I was tired of manually changing the configuration file. There is already mry gem that solves the same problem, but it's a bit outdated.

This gem handles rubocop's stderr output, therefore it won't shouldn't get outdated. More info about how this gem works and what kind of errors it deals with, can be found in the section #how-it-works

Install

Add this line to your application's Gemfile:

gem 'rubocop_config_updater', require: false

And then execute:

bundle install

Or preferred install it yourself as:

gem install rubocop_config_updater

After usage you can uninstall with:

gem cleanup rubocop_config_updater

Usage: rubocop_config_updater [options]
    -c, --config PATH                Rubocop config path, i.e. .rubocop.yml
        --rubocop COMMAND            Rubocop command, i.e. bundle exec rubocop
    -v, --version

This gem runs a command against rubocop and collects errors from STDERR, which are used to update rubocop's configuration file. If you are interested in Rubocop's code responsible for the above mentioned errors, here is a link to Rubocop's config_obsoletion class
