Overview

Ensures magic comments are written consistently throughout your code base. Looks for discrepancies in separators (- vs _) and capitalization for both magic comment directives and values.

Required capitalization can be set with the DirectiveCapitalization and ValueCapitalization configuration keys.

Note	If one of these configuration is set to nil, any capitalization is allowed.

Examples:

EnforcedStyle: snake_case (default)

# The `snake_case` style will enforce that the frozen string literal
# comment is written in snake case. (Words separated by underscores)
# bad
# frozen-string-literal: true

module Bar
  # ...
end

# good
# frozen_string_literal: false

module Bar
  # ...
end

EnforcedStyle: kebab_case

# The `kebab_case` style will enforce that the frozen string literal
# comment is written in kebab case. (Words separated by hyphens)
# bad
# frozen_string_literal: true

module Baz
  # ...
end

# good
# frozen-string-literal: true

module Baz
  # ...
end

DirectiveCapitalization: lowercase (default)

# bad
# FROZEN-STRING-LITERAL: true

# good
# frozen-string-literal: true

DirectiveCapitalization: uppercase

# bad
# frozen-string-literal: true

# good
# FROZEN-STRING-LITERAL: true

DirectiveCapitalization: nil

# any capitalization is accepted

# good
# frozen-string-literal: true

# good
# FROZEN-STRING-LITERAL: true

ValueCapitalization: nil (default)

# any capitalization is accepted

# good
# frozen-string-literal: true

# good
# frozen-string-literal: TRUE

ValueCapitalization: lowercase

# when a value is not given, any capitalization is accepted

# bad
# frozen-string-literal: TRUE

# good
# frozen-string-literal: TRUE

ValueCapitalization: uppercase

# bad
# frozen-string-literal: true

# good
