Defined in:
lib/rubocop/cop/layout/multi_line_block_spacing.rb

Overview

Requires a blank line between two consecutive statements when either of them spans multiple lines. Adjacent single-line statements need no blank line. The boundary with the enclosing ‘def`/`do`/`end` is left to other cops.

Detection-only (no autocorrect) for now — the comment-handling and autocorrect behaviour need validation against the real repos first.

Examples:

# bad
foo(
  bar
)
baz

# good
foo(
  bar
)

baz
