Rubocop::Diff
Rubocop-diff runs rubocop, but gives you a report only for the lines you have changed. This can be useful in particularly nasty projects where you can't fix entire files at a time.
Manual Dependencies
Git: You will need git installed as rubocop-diff uses it to to figure out the diff
Installation
You probably have rubocop installed globally, so you want rubocop-diff installed globally too.
$ gem install rubocop-diff
Or, you could add this line to your application's Gemfile:
gem 'rubocop-diff'
And then execute:
$ bundle
Usage
Just run
$ rubocop-diff
in your working directory
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
. 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 rubygems.org.
