Overview

This cop checks that the closing brace in a method definition is either on the same line as the last method parameter, or a new line.

When using the ‘symmetrical` (default) style:

If a method definition’s opening brace is on the same line as the first parameter of the definition, then the closing brace should be on the same line as the last parameter of the definition.

If an method definition’s opening brace is on the line above the first parameter of the definition, then the closing brace should be on the line below the last parameter of the definition.

When using the ‘new_line` style:

The closing brace of a multi-line method definition must be on the line after the last parameter of the definition.

When using the ‘same_line` style:

The closing brace of a multi-line method definition must be on the same line as the last parameter of the definition.

Examples:


# symmetrical: bad
# new_line: good
# same_line: bad
def foo(a,
  b
)

# symmetrical: bad
# new_line: bad
# same_line: good
def foo(
  a,
  b)

# symmetrical: good
# new_line: bad
# same_line: good
def foo(a,
  b)

# symmetrical: good
# new_line: good
# same_line: bad
def foo(
  a,
  b
)
