Overview

Detects comments to enable/disable RuboCop. This is useful if you want to make sure that every RuboCop error gets fixed and not quickly disabled with a comment.

Specific cops can be allowed with the AllowedCops configuration. Note that if this configuration is set, rubocop:disable all is still disallowed.

Alternatively, specific cops can be disallowed with the DisallowedCops configuration. When DisallowedCops is set, only directives for the listed cops (and all) will be flagged. This is useful when you want to protect a small set of critical cops from being disabled rather than allowlisting all other cops. AllowedCops and DisallowedCops should not both be set at the same time; if DisallowedCops is set, it takes precedence.

This cop cannot be disabled via directive comments when it is explicitly enabled with Enabled: true. This prevents users from bypassing the cop with # rubocop:disable Style/DisableCopsWithinSourceCodeDirective.

Examples:

# bad
# rubocop:disable Metrics/AbcSize
def foo
end
# rubocop:enable Metrics/AbcSize

# good
def foo
end

AllowedCops: [Metrics/AbcSize]

# good
# rubocop:disable Metrics/AbcSize
def foo
end
# rubocop:enable Metrics/AbcSize

DisallowedCops: [Lint/Void]

# bad
# rubocop:disable Lint/Void
foo
# rubocop:enable Lint/Void

# good
# rubocop:disable Metrics/AbcSize
foo
# rubocop:enable Metrics/AbcSize
