Overview

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.

This Layout/EndAlignment cop aligns with keywords (e.g. if, while, case) by default. On the other hand, Layout/BeginEndAlignment cop aligns with EnforcedStyleAlignWith: start_of_line by default due to ||= begin tends to align with the start of the line. These style can be configured by each cop.

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
