Rubocop gets angry when I try to fill zeros (fill 0s) with Ruby

problem

rubocop got angry ... scary ...

C: Style/FormatStringToken: Prefer annotated tokens (like %<foo>s) over unannotated tokens (like %s).
        format('number: %03d', 1)
                        ^^^^

Solution

In format, you can set the argument specification using hash, so avoid it there.

format("number: %03<number>d", number: 1)
#=> "number: 001"
