Overview

This cop checks that the closing brace in a hash literal is either on the same line as the last hash element, or a new line.

When using the `symmetrical` (default) style:

If a hash's opening brace is on the same line as the first element of the hash, then the closing brace should be on the same line as the last element of the hash.

If a hash's opening brace is on the line above the first element of the hash, then the closing brace should be on the line below the last element of the hash.

When using the `new_line` style:

The closing brace of a multi-line hash literal must be on the line after the last element of the hash.

When using the `same_line` style:

The closing brace of a multi-line hash literal must be on the same line as the last element of the hash.

Examples:

EnforcedStyle: symmetrical (default)

  b: 2 }

}
