Overview

Checks whether the end keyword of begin is 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 begin keyword is. If it's set to begin, the end shall be aligned with the begin keyword.

Layout/EndAlignment cop aligns with keywords (e.g. if, while, case) by default. On the other hand, ||= begin that this cop targets tends to align with the start of the line, it defaults to EnforcedStyleAlignWith: start_of_line. These styles can be configured by each cop.

Examples:

EnforcedStyleAlignWith: start_of_line (default)

# bad
foo ||= begin
          do_something
        end

# good
foo ||= begin
  do_something
end

EnforcedStyleAlignWith: begin

# bad
foo ||= begin
  do_something
end

# good
foo ||= begin
          do_something
        end
