Rubocop Obsession
A RuboCop extension that focuses on higher-level concepts, like checking that code reads from top to bottom, or only unit testing public methods. There are some lower-level cops as well.
Use the provided cops as is, or as inspiration to build custom cops aligned with your project's best practices.
Does your project have any cool custom cops that you think others might benefit from? Then please open a PR!
Installation
Install the gem:
gem install rubocop-obsession
Or add this line to your Gemfile:
gem 'rubocop-obsession', require: false
and run bundle install
.
Usage
You need to tell Rubocop to load the Obsession extension. There are three ways to do this:
Rubocop configuration file
Put this into your .rubocop.yml
.
require: rubocop-obsession
Alternatively, use the following array notation when specifying multiple extensions.
require:
- rubocop-other-extension
- rubocop-obsession
Now you can run rubocop
and it will automatically load the Rubocop Obsession
cops together with the standard cops.
Command line
rubocop --require rubocop-obsession
Rake task
RuboCop::RakeTask.new do |task|
task.requires << 'rubocop-obsession'
end
The cops
All cops are located under
lib/rubocop/cop/obsession
, and contain examples
and documentation. Their default configuration is defined in
config/default.yml
.
These cops are opinionated and can feel like too much, that is why some of them are disabled by default. Do not hesitate to enable or disable them as needed.
I wrote them to scratch an itch I had at one point or another. Tastes change with time, and I personally do not use some of them any more, but others might find them useful.
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 the created tag, and push the .gem
file to rubygems.org.
