Overview

This cop 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 style 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
