class RuboCop::Cop::Style::ClosingParenthesisIndentation
This cops checks the indentation of hanging closing parentheses in method calls, method definitions, and grouped expressions. A hanging closing parenthesis means `)` preceded by a line break.
@example
# good: when x is on its own line, indent this way func( x, y ) # good: when x follows opening parenthesis, align parentheses a = b * (x + y ) # bad def func( x, y )
Constants
- MSG_ALIGN
