Overview

Checks for inconsistent indentation.

The difference between indented_internal_methods and normal is that the indented_internal_methods style prescribes that in classes and modules the protected and private modifier keywords shall be indented the same as public methods and that protected and private members shall be indented one step more than the modifiers. Other than that, both styles mean that entities on the same logical depth shall have the same indentation.

Examples:

EnforcedStyle: normal (default)

# bad
class A
  def test
    puts 'hello'
     puts 'world'
  end
end

# bad
class A
  def test
    puts 'hello'
    puts 'world'
  end

  protected

    def foo
    end

  private

    def bar
    end
end

# good
class A
  def test
    puts 'hello'
    puts 'world'
  end
end

# good
class A
  def test
    puts 'hello'
    puts 'world'
  end

  protected

  def foo
  end

  private

  def bar
  end
end

EnforcedStyle: indented_internal_methods

# bad
class A
  def test
    puts 'hello'
     puts 'world'
  end
end

# bad
class A
  def test
    puts 'hello'
    puts 'world'
  end

  protected

  def foo
  end

  private

  def bar
  end
end

# good
class A
  def test
    puts 'hello'
    puts 'world'
  end
end

# good
class A
  def test
    puts 'hello'
    puts 'world'
  end

  protected

    def foo
    end

  private

    def bar
    end
end

#add_global_offense

Adds an offense that has no particular location.
#add_offense

Adds an offense on the specified range (or node with an expression) Unless that offense is disabled for this range, a corrector will be yielded to provide the cop the opportunity to autocorrect the offense.

Called before any investigation.

This method should be overridden when a cop’s behavior depends on state that lives outside of these locations:
#inspect,
#message

Gets called if no message is specified when calling add_offense or add_global_offense Cops are discouraged to override this; instead pass your message directly.

#autocorrect(corrector, node) (private)

[ GitHub ] 

  


# File 'lib/rubocop/cop/layout/indentation_consistency.rb', line 138



def autocorrect(corrector, node)
  AlignmentCorrector.correct(corrector, processed_source, node, column_delta)

    #bare_access_modifier?(node)  ⇒ Boolean  (private)
  



  

    


Not all nodes define bare_access_modifier? (for example,
RuboCop::AST::DefNode does not), so we must check send_type? first
to avoid a NoMethodError.

    #base_column_for_normal_style(node)   (private)
  



  

    


Returns an integer representing the correct indentation, or nil to
indicate that the correct indentation is that of the first child that
is not an access modifier.

  # the module (`access_modifier_indent > module_indent`) then the
  # indentation of the access modifier determines the correct
  # indentation.
  #
  # Otherwise, in the rare event that the access modifier is outdented
  # to the level of the module (see `AccessModifierIndentation` cop) we
  # return nil so that `check_alignment` will derive the correct
  # indentation from the first child that is not an access modifier.
