RuboCop Ipepe

RuboCop.

Installation

Just install the rubocop-ipepe gem

“sh gem install rubocop-ipepe

“

or if you use bundler put this in your Gemfile

“by gem ‘rubocop-ipepe’, require: false

“

Usage

You need to tell RuboCop to load the Ipepe extension. There are three ways to do this:

RuboCop configuration file

Put this into your .rubocop.yml.

“ml require: rubocop-ipepe

“

Alternatively, use the following array notation when specifying multiple extensions.

“ml require: - rubocop-other-extension - rubocop-ipepe

“

Now you can run rubocop and it will automatically load the RuboCop Ipepe cops together with the standard cops.

Command line

“sh rubocop –require rubocop-ipepe

“

Rake task

“by RuboCop::RakeTask.new do |task| task.requires « ‘rubocop-ipepe’ end

“

The Cops

All cops are located under lib/rubocop/cop/ipepe, and contain examples/documentation.

In your .rubocop.yml, you may treat the Ipepe cops just like any other cop. For example:

“ml Ipepe/SpecificMatcher: Exclude: - spec/my_spec.rb

“

Ipepe/MultipleConditionUnless

Checks for multiple conditions in unless statement.

“by

bad

unless foo && bar do_something end

good

if foo || bar do_something end

“

Ipepe/TernaryOperator

Prohibits any use of ternary operator.

“by

bad

foo ? bar : baz

good

if foo bar else baz end

“

Development

Adding a new cop

bundle exec rake 'new_cop[Ipepe/TestOperator]'
