class RuboCop::Cop::Layout::MultilineMethodArgumentLineBreaks
Ensures that each argument in a multi-line method call 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/FirstMethodArgumentLineBreak`.
@example
# bad foo(a, b, c ) # bad foo(a, b, { foo: "bar", }) # good foo( a, b, c ) # good foo(a, b, c)
@example AllowMultilineFinalElement: false (default)
# good foo( a, b, { foo: "bar", } )
@example AllowMultilineFinalElement: true
# good foo( a, b, { foo: "bar", } )
