Pronto runner for RuboCop

Code Climate Build Status Gem Version

Pronto runner for RuboCop, ruby code analyzer. What is Pronto?

Configuration

Configuring RuboCop via .rubocop.yml will work just fine with pronto-rubocop.

You can also specify a custom .rubocop.yml location with the environment variable RUBOCOP_CONFIG.

You can also provide additional configuration via .pronto.yml:

rubocop:
  # Map of RuboCop severity level to Pronto severity level
  severities:
    refactor: info
    warning: error

  # Enable suggestions
  suggestions: true

Suggestions

When suggestions are enabled, the messages will include a line suggesting what to change, using GitHub's syntax on Pull Request reviews, that can be approved in one click right from the Pull Request.

For example:

RuboCop versions

If you need to use RuboCop v0.84.0 or v0.85.x, you'll need to ensure that you've also need to add gem 'rubocop-ast', '< 0.7.0' to your Gemfile as these were the first versions to use rubocop-ast, and unfortunately the dependency was loose enough that rubocop-ast versions >= 0.7.0 were allowed, which causes require 'rubocop' to fail with

  NoMethodError:
    undefined method `join' for #<Set: {:==, :===, :!=, :<=, :>=, :>, :<}>
  in rubocop-0.84.0/lib/rubocop/cop/style/redundant_conditional.rb:57:in `<class:RedundantConditional>'

This is due to rubocop/rubocop-ast#22
