Hi all K Is there any way to disable asserted !! calls altogether?

[danny]

Often unavoidable when you have interop with null permissive libraries and when Kotlin can’t infer non-nullability

[danny]

A job for https://github.com/shyiko/ktlint perhaps?

[danny]

I definitely prefer !! or elvis, to null safe operators

[karelpeeters]

Elvis and !! are not comparable at all.

[karelpeeters]

I'd even say that !! is almost never a good idea.

[danny]

Failing fast on null isn’t a good idea?

[danny]

It’s just shorthand for ?: throw ... if you prefer elvis

[karelpeeters]

Yes I know that, but if one of the parameters of your method is nullable and you're going to fail-fast anyway, you shouldn't have made that parameter nullable.

[karelpeeters]

Unless there's a usecase i'm missing?

[danny]

Java interop

[danny]

I agree completely when you’re talking all Kotlin code, in that case nullability in your type signature is hopefully communicating a contract akin to Optional

[danny]

But when you’re interoping with Java code, all bets are off

[karelpeeters]

As soon as those platform types are converted to non-nullable Kotlin types an exception is thrown automatically, no?

[gregd]

I agree with @karelpeeters To be honest, I’ve never had a situation where !! would give me any advantage at all
