[Question] Accessing array elements in a configuration

[maasg]

Given a nested JSON as configuration, like:

{
    app: {
        id: "app1"
        instances: 2,
        servers: [
            { host: "farm1.myco.com", port: 9876 }
            { host: "farm2.myco.com", port: 9876 }
        ]
    }
}

is it possible to address elements of an array directly in a path?

At the moment we need to do something like the following, which is kind of verbose:

val servers = config.getObjectList("app.id")
val server = servers.get(0).toConfig
val host = server.getString("host")
val port = server.getInt("port")

Something like this would be ideal:

val host = config.getString("app.id.servers.0.host") ?

Does the TypeSafe API supports something like this?

There isn't a way now; I think #30 is the same request and has some (not very enlightening) discussion.

I see. Thanks.

For the record, my usecase is accessing some config in json format in which a list of servers is written by the config system (e.g Chef in our case) but where I only need the first element ("seed node"). It should be a valid usecase for a configuration and having to drop down to an array and go back to a config object seems to be like a broken path to me.

Let's call this a duplidate of #30, so I'll close this copy.
