Ruby

• Rubocop

Rubocop Config file

• .github/linters/.ruby-lint.yml
• You can pass multiple rules and overwrite default rules
• File should be located at: .github/linters/.ruby-lint.yml
• Note: We use the Default GitHub Rule set from Rubocop-GitHub

Rubocop disable single line

method(argument) # rubocop:disable SomeRule, SomeOtherRule

Rubocop disable code block

# rubocop:disable
This is a long line
var="this is some other stuff"
# rubocop:enable

Rubocop disable entire file

If you need to ignore an entire file, you can update the .github/linters/.ruby-lint.yml to ignore certain files and locations

inherit_from:
  - .rubocop_todo.yml
  - .rubocop_app_overrides.yml

inherit_mode:
  merge:
    - Exclude

Rails:
  Enabled: true

AllCops:
  TargetRubyVersion: 2.5.1
  EnabledByDefault: true
  Exclude:
    - 'db/**/*'
    - 'config/**/*'
    - 'script/**/*'
    - 'bin/{rails,rake}'
    - !ruby/regexp /old_and_unused\.rb$/
