BoochTek's shared RuboCop configuration for Ruby projects.

Add to your Gemfile:

group :development, :test do
  gem "rubocop-boochtek", github: "boochtek/rubocop-boochtek"
end

Or install directly:

gem install rubocop-boochtek

Create a .rubocop.yml in your project root:

plugins:
  - rubocop-boochtek

That's it! The gem automatically loads rubocop-rspec and rubocop-performance.

Override any settings in your project's .rubocop.yml:

plugins:
  - rubocop-boochtek

Layout/LineLength:
  Max: 160

AllCops:
  NewCops: enable

We prefer private def over a separate private section:

# Good
private def my_method
  # ...
end

# Avoided
private

def my_method
  # ...
end

This makes it easier to see at a glance which methods are private, and makes moving methods around simpler.

Use {} for blocks that return a value; use do/end otherwise:

# Good - returns a value
names = users.map { |u| u.name }

# Good - side effects only
users.each do |user|
  send_email(user)
end

We use double quotes by default for strings, as they require fewer changes when you later need interpolation.

• Line length: 120 characters
• No frozen string literal comments required
• No documentation required for classes/modules
• fail for raising exceptions, raise for re-raising
• %x[] for shell commands (not backticks)
• Unicode allowed in comments and identifiers

Create cops in lib/rubocop/cop/boochtek/:

# lib/rubocop/cop/boochtek/my_custom_cop.rb
module RuboCop
  module Cop
    module Boochtek
      class MyCustomCop < Base
        MSG = "Custom message here"

        def on_send(node)
          # ...
        end
      end
    end
  end
end

Custom cops are auto-loaded when the gem is required.
