MeowCop

Gem Version

MeowCop is a gem for RuboCop configuration, it focuses Lint. It's recommended by Sider, Inc.

Design

RuboCop has many style cops. Style cops provide one of several settings. So, sometime we get many many warnings when we introduce RuboCop. The cause is a mismatch between RuboCop's default setting and your project coding style.

In the configuration, style rules are disabled. Because the rules almost for project specific. If you use, you can use RuboCop as a Linter without many noisy warnings.

If you want to use RuboCop as a style checker, we recommend Gry.

Installation

Add this line to your application's Gemfile:

gem 'meowcop'

And then execute:

$ bundle

Or install it yourself as:

$ gem install meowcop

Configuration
