class RuboCop::Cop::Layout::AlignParameters
Here we check if the parameters on a multi-line method call or definition are aligned.
To set the alignment of the first argument, use the cop FirstParameterIndentation.
@example EnforcedStyle: with_first_parameter (default)
# good def foo(bar, baz) 123 end def foo( bar, baz ) 123 end # bad def foo(bar, baz) 123 end # bad def foo( bar, baz) 123 end
@example EnforcedStyle: with_fixed_indentation
# good def foo(bar, baz) 123 end def foo( bar, baz ) 123 end # bad def foo(bar, baz) 123 end # bad def foo( bar, baz) 123 end
Constants
