hi all! does graphql-kotlin-server support scalar definitions for kotlin value classes ?

👋 they are in the 6.x (still alpha) but its not yet documented

TLDR you would need to do something similar as we did for handling the ID (https://opensource.expediagroup.com/graphql-kotlin/docs/schema-generator/writing-schemas/scalars#primitive-types)

[vio]

thank you 🙏 trying it out now

sorry, could it be that I'm missing something when I try to set this up? my schema doesn't seem to pick up the unboxing

the value class:

@JvmInline
value class BookId(
    val v: String
)

the value unboxer definition:

open class BookIdValueUnboxer : ValueUnboxer {
    override fun unbox(`object`: Any?): Any? = if (`object` is BookId) {
         // log.debug { "Unboxing value: $`object`" }
        `object`.v
    } else {
        `object`
    }
}

and the registration to the GraphQL instance:

GraphQL
     .newGraphQL(schema)
     .valueUnboxer(BookIdValueUnboxer())
     .build()

I'll take a look tomorrow

hi 👋
sorry for the delay, it looks like inline value class may require some additional changes to make it work
