Receive Array

[dragazo]

Adds support for receiving builtin js arrays in When I receive blocks. This seems like it would have no side effects since builtin js arrays are not an allowed snap primitive.

Thanks, @dragazo! I suspect this is to make things easier with the PyBlocks integration?

This change should be fine but should happen when the message is deserialized rather than in the process itself. The logic itself can get a little hairy when you get into how the serializer is used to deserialize these (it isn't completely decoupled from the IDE in Snap) but you should be able to avoid all that since this is a pretty minor high-level change :)

It would be nice to add a test, too. Not necessarily a deal-breaker since it is such a minor change but it would be nice to have it at least for regression testing.

@brollb Oh, btw I updated to move the logic to the deserializer, but haven't added tests yet. But this is ultra-non-critical, I know you're busy :)

This actually came up while extending the CloudVariables service, since listen events were trying to send back json from the db (apparently sending messages weren't going through the same conversions as rpc return values). But you're right it'll also allow pyblox clients to send arrays and structured data to netsblox clients.

@dragazo Add object support?
