class RuboCop::Cop::Layout::FirstMethodArgumentLineBreak
Checks for a line break before the first argument in a multi-line method call.
@example
# bad method(foo, bar, baz) # good method( foo, bar, baz) # ignored method foo, bar, baz
@example AllowMultilineFinalElement: false (default)
# bad method(foo, bar, { baz: "a", qux: "b", }) # good method( foo, bar, { baz: "a", qux: "b", })
@example AllowMultilineFinalElement: true
# bad method(foo, bar, { baz: "a", qux: "b", } ) # good method(foo, bar, { baz: "a", qux: "b", }) # good method( foo, bar, { baz: "a", qux: "b", } )
@example AllowedMethods: [‘some_method’]
# good some_method(foo, bar, baz)
