Docquet

A standardized RuboCop configuration gem that automatically detects available RuboCop plugins and generates appropriate configurations with CLI tools for easy setup and maintenance.

• Automatic Plugin Detection: Automatically detects installed RuboCop plugins and includes their configurations
• CLI Tools: Easy-to-use commands for initialization and maintenance
• Comprehensive Coverage: Supports all major RuboCop plugins out of the box
• Documentation Links: Generated configurations include links to official documentation
• Smart Detection: Uses gem metadata to automatically detect installed RuboCop plugins
• Incremental Setup: Generates .rubocop_todo.yml for gradual adoption

Add it to your Gemfile:

group :development do
  gem "docquet", require: false
end

Then run:

bundle install

Or install it as a standalone gem:

gem install docquet

Run the installation command in your project root:

docquet install-config

This command will:

1. Generate .rubocop.yml with configurations for detected plugins
2. Create an initial .rubocop_todo.yml with existing violations
3. Display next steps for gradual adoption

To overwrite existing files:

docquet install-config --force

When you've fixed some violations and want to regenerate the TODO file:

docquet regenerate-todo

This command will:

• Regenerate .rubocop_todo.yml with current violations
• Show whether the TODO file changed
• Provide feedback on progress

The gem automatically detects and configures the following plugins when installed:

• Bundler: Bundler-related rules
• Gemspec: Gemspec file rules
• Layout: Code formatting and layout rules
• Lint: Rules for catching potential bugs
• Metrics: Code complexity and size metrics
• Naming: Naming convention rules
• Security: Security-related rules
• Style: General code style rules

• rubocop-capybara: Capybara testing framework rules
• rubocop-i18n: Internationalization rules (GetText, Rails I18n)
• rubocop-migration: Database migration rules (for Rails applications)
• rubocop-performance: Performance optimization rules
• rubocop-rake: Rake task rules
• rubocop-rspec: RSpec testing framework rules (including Capybara integration)
• rubocop-sequel: Sequel ORM rules
• rubocop-thread_safety: Thread safety rules

The generated .rubocop.yml file includes:

AllCops:
  DisplayCopNames: true
  DisplayStyleGuide: true
  EnabledByDefault: true
  Exclude:
    - bin/**/*
    - vendor/**/*
  ExtraDetails: true
  NewCops: enable
  TargetRubyVersion: 3.2  # Detected from .ruby-version or current Ruby
  UseCache: true

plugins:
  - rubocop-performance  # Auto-detected plugins
  - rubocop-rspec
  # ... other detected plugins

inherit_gem:
  docquet:
    - config/cops/style.yml        # Core style rules
    - config/cops/layout.yml       # Core layout rules
    - config/cops/performance.yml  # Performance rules (if plugin detected)
    - config/cops/rspec.yml        # RSpec rules (if plugin detected)
    # ... other detected plugins

inherit_from: .rubocop_todo.yml

Each configuration file includes:

• Department-specific rules
• Links to official RuboCop documentation
• Carefully curated cop configurations
• Optimized settings for practical use

The configuration uses EnabledByDefault: true for strict code quality enforcement with TODO file for gradual adoption.

This configuration aims to:

1. Enforce Consistency: Standardize code style across projects
2. Promote Best Practices: Enable rules that catch common issues
3. Provide Documentation: Include links to understand each rule
4. Enable Gradual Adoption: Use TODO files for incremental improvements
5. Stay Current: Automatically adapt to installed plugin versions
