ALERT: WORK IN PROGRESS 🚧
This is a fork and rename of rubocop
It is in the process of being renamed to ruby_lint in all of the places
The goal of this project is for the rubocop folks to merge this back into rubocop project, and rename its org/repo/domain/etc
The goal is NOT to maintain an ongoing parity fork of an active project
PRs are welcome and appreciated ❤️
Role models are important.
-- Officer Alex J. Murphy / RoboCop
RuboCop is a Ruby static code analyzer (a.k.a. linter) and code formatter. Out of the box it
will enforce many of the guidelines outlined in the community Ruby Style
Guide. Apart from reporting the problems discovered in your code,
RuboCop can also automatically fix many of them you.
RuboCop is extremely flexible and most aspects of its behavior can be tweaked via various configuration options.
Please consider financially supporting its ongoing development.
Installation
RuboCop's installation is pretty standard:
$ gem install rubocopIf you'd rather install RuboCop using bundler, add a line for it in your Gemfile (but set the require option to false, as it is a standalone tool):
gem 'rubocop', require: falseRuboCop's development is moving at a very rapid pace and there are
often backward-incompatible changes between minor releases (since we
haven't reached version 1.0 yet). To prevent an unwanted RuboCop update you
might want to use a conservative version lock in your Gemfile:
gem 'rubocop', '~> 0.85.0', require: falseQuickstart
Just type rubocop in a Ruby project's folder and watch the magic happen.
$ cd my/cool/ruby/project
$ rubocop

Contributors
Here's a list of all the people who have contributed to the development of RuboCop.
I'm extremely grateful to each and every one of them!
If you'd like to contribute to RuboCop, please take the time to go through our short contribution guidelines.
Converting more of the Ruby Style Guide into RuboCop cops is our top priority right now. Writing a new cop is a great way to dive into RuboCop!
Of course, bug reports and suggestions for improvements are always welcome. GitHub pull requests are even better! :-)
Funding
While RuboCop is free software and will always be, the project would benefit immensely from some funding. Raising a monthly budget of a couple of thousand dollars would make it possible to pay people to work on certain complex features, fund other development related stuff (e.g. hardware, conference trips) and so on. Raising a monthly budget of over $5000 would open the possibility of someone working full-time on the project which would speed up the pace of development significantly.
We welcome both individual and corporate sponsors! We also offer a wide array of funding channels to account for your preferences (although currently Open Collective is our preferred funding platform).
If you're working in a company that's making significant use of RuboCop we'd appreciate it if you suggest to your company to become a RuboCop sponsor.
You can support the development of RuboCop via GitHub Sponsors, Patreon, PayPal and Open Collective.
