Defined in:

Overview

This cop checks whether the end keywords of method definitions are aligned properly.

Two modes are supported through the EnforcedStyleAlignWith configuration parameter. If it's set to `start_of_line` (which is the default), the `end` shall be aligned with the start of the line where the `def` keyword is. If it's set to `def`, the `end` shall be aligned with the `def` keyword.

Examples:

EnforcedStyleAlignWith: start_of_line (default)

# bad

private def foo
            end

# good

private def foo
end

EnforcedStyleAlignWith: def

# bad

private def foo
            end

# good

private def foo
        end
