Delete Setting API

[SaeedZhiany]

Is there any delete API that completely deletes the underlying key-value storage? What I'm looking for is different from the API clear, I don't want to clear all key values within the storage, but remove the storage itself.

for example, we can use this code:

Android:

context.deleteSharedPreferences("STORAGE_NAME")

Windows:

fun remove() = memScoped {
    val hkey = alloc<HKEYVar>()
    try {
        RegDeleteKeyExW(
            HKEY_CURRENT_USER,
            rootKeyName,
            (KEY_READ or KEY_WRITE).toUInt(),
            0u,
        ).checkWinApiSuccess { "Unable to create/open registry key for \"$rootKeyName\"" }
    } finally {
    }
}

and similarly, I expect such functionality should be available in the other platforms, so we can use them and implement the API in the library.

If it's not included in this library, is there any plan to support such functionality?

Thanks

There's no API for this currently. It's not a need that I'm very aware of. Can you say more about your use-case and why clear() isn't enough?

I'm working on a Kotlin Multiplatform application that needs to dynamically create many temporary key-value storages (KVS) as the user demands and then remove the file because I don't want to keep many empty KVS on users' devices. so I'm looking for an approach to delete the storage instead of clearing its content.

Ok, I can see the purpose here, but I don't think there's a good way to do it in a backwards-compatible way. I also haven't investigated whether all implementation APIs support a delete operation, though I'd consider just falling back to clear() when there's no other way to do delete(). I'm going to consider this for a potential 2.0 release, but don't expect that to happen very soon.
