Defined in:

Overview

This cop 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.

Examples:


# bad
some_method(
  a,
  b
  )

some_method(
  a, b
  )

some_method(a, b, c
  )

some_method(a,
            b,
            c
  )

some_method(a,
  x: 1,
  y: 2
  )

# Scenario 1: When First Parameter Is On Its Own Line

# good: when first param is on a new line, right paren is *always*
#       outdented by IndentationWidth
some_method(
  a,
  b
)

# good
some_method(
  a, b
)

# Scenario 2: When First Parameter Is On The Same Line

# good: when all other params are also on the same line, outdent
#       right paren by IndentationWidth
some_method(a, b, c
           )

# good: when all other params are on multiple lines, but are lined
#       up, align right paren with left paren
some_method(a,
            b,
            c
           )

# good: when other params are not lined up on multiple lines, outdent
#       right paren by IndentationWidth
some_method(a,
  x: 1,
  y: 2
)
