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. `Layout/DefEndAlignment` cop also aligns with `EnforcedStyleAlignWith: start_of_line` by default. 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
