Hi, how can I @sprintf an integer i padded to length l with zeros, where l is not a constant? Current workaround is
printpad(i, l) = mapreduce(string, *, reverse(digits(i, 10, l)))
julia> printpad(12, 4)
"0012"
but I could not figure out how to do this with @sprintf. If my
understanding of printf syntax is correct, something like
@sprintf("%*d", 4, 12)
should do the trick, but in Julia it is an invalid format string.
Best,
Tamas
