CSSOM. Unable to set gridRow and gridColumn properties

[aerialist7]

Hello,

I'm trying to make the same as in the example of grid-row from MDN, but I can't do it without unsafeCast, because there are no GridRow/GridColumn factories (even no something like array/many factories but with "/" as a separator).

gridRow = "1 / 3".unsafeCast<GridRow>()
gridRow = "auto / span 2".unsafeCast<GridRow>()
gridColumn = "auto / span 2".unsafeCast<GridColumn>()

Is there any way to do it without casting?

Which API do you expect in described cases?

I think the generic case should be supported at least.
Because array and many already exist.
And something similar (but joining via "/") should also be available in the wrappers.

Examples of calls will be very helpful

I wrote them in the first message.
IMO in a first approximation they can be rewritten as

gridRow = multiple(integer(1), integer(3))
gridRow = multiple(auto, array(span, integer(2)))
gridColumn = multiple(auto, array(span, integer(2)))

where multiple (name could be better of cause) is

fun <T : Any> multiple(
    vararg values: T,
): T =
    values.joinToString(" / ")
        .unsafeCast<T>()

GridRow and GridColumn have strict signatures and multiple doesn't look like solution for them

[aerialist7]

Ok, then can it be done via corresponding factories for GridRow and GridColumn?

GridRow(GridRowStart, GridRowEnd)
GridColumn(GridColumnStart, GridColumnEnd)
