Gem Version

This gem provides you with a rake task to install rubocop as a git pre-commit hook. If rubocop finds any issues it will abort the commit. It will try to auto-correct all issues in the files that are being commited, but will abort the commit even if all issues can be auto-corrected so that you can verify the changes before actually commiting them.

Although this gem has no tests it's battle tested and is in use at runtastic since years.


Add these lines to your application's Gemfile:

gem 'rubocop_runner', '~> 2.1', require: false

And then execute:

$ bundle

Or install it yourself as:

$ gem install rubocop_runner


To create a rubocop runner pre-commit hook once just run

ruby -rrubocop_runner -e "RubocopRunner.install"

To make it easy for every developer on the project you can also add this to your Rakefile:

require 'rubocop_runner/rake_task'

Afterwards, just run the rake rubocop:install task to install the pre-commit hook.


After checking out the repo, run bin/setup to install dependencies. 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. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to
