Includes:

MultilineElementLineBreaks

Defined in:

lib/rubocop/cop/layout/multiline_method_parameter_line_breaks.rb

Overview

Ensures that each parameter in a multi-line method definition starts on a separate line.

NOTE: This cop does not move the first argument, if you want that to be on a separate line, see ‘Layout/FirstMethodParameterLineBreak`.

Examples:

# bad
def foo(a, b,
  c
)
end

# good
def foo(
  a,
  b,
  c
)
end

# good
def foo(
  a,
  b = {
    foo: "bar",
  }
)
end

# good
def foo(a, b, c)
end

AllowMultilineFinalElement: false (default)

# bad
def foo(a, b = {
  foo: "bar",
})
end

AllowMultilineFinalElement: true

# good
def foo(a, b = {
  foo: "bar",
})
end
