Defined in:

Overview

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
