Overview

This cop checks that the closing brace in an array literal is symmetrical with respect to the opening brace and the array elements.

If an array’s opening brace is on the same line as the first element of the array, then the closing brace should be on the same line as the last element of the array.

If an array’s opening brace is on a separate line from the first element of the array, then the closing brace should be on the line after the last element of the array.

Examples:


# bad
[ :a,
  :b
]

# bad
[
  :a,
  :b ]

# good
[ :a,
  :b ]

#good
[
  :a,
  :b
]
