Alignment, CheckAssignment
Defined in:
lib/rubocop/cop/layout/indent_assignment.rb

Overview

This cop checks the indentation of the first line of the right-hand-side of a multi-line assignment.

The indentation of the remaining lines can be corrected with other cops such as ‘IndentationConsistency` and `EndAlignment`.

Examples:

# bad
value =
if foo
  'bar'
end

# good
value =
  if foo
    'bar'
  end
