Defined in:

Overview

This cop checks whether the end keywords are aligned properly.

Three modes are supported through the ‘EnforcedStyleAlignWith` configuration parameter:

If it’s set to ‘keyword` (which is the default), the `end` shall be aligned with the start of the keyword (if, class, etc.).

If it’s set to ‘variable` the `end` shall be aligned with the left-hand-side of the variable assignment, if there is one.

If it’s set to ‘start_of_line`, the `end` shall be aligned with the start of the line where the matching keyword appears.

Examples:

EnforcedStyleAlignWith: keyword (default)

# bad

variable = if true
    end

# good

variable = if true
           end

variable =
  if true
  end

EnforcedStyleAlignWith: variable

# bad

variable = if true
    end

# good

variable = if true
end

variable =
  if true
  end

EnforcedStyleAlignWith: start_of_line

# bad

variable = if true
    end

puts(if true
     end)

# good

variable = if true
end

puts(if true
end)

variable =
  if true
  end
