running pkl eval Conn.pkl

also, i know that i wasnt using the types right, but the IDE didn't say anything and i wanted to see what would happen :)

file Conn.pkl:

open module Conn

import "Conn.pkl"

conn_id: String = ""

const local function conn(id: String): Conn = new Conn { conn_id = id }

function s3(_bucket: String) = new Mixin<S3> {
  bucket = _bucket
}

connections = new Mapping {
  default { key ->
    conn_id = "\(key)_cloud"
  }
  ["bento"] {}
  ["idp"] {}
  ["databricks"] {}
  ["polaris_api"] = conn("polaris_api")
  ["samba"] = conn("nas_drive")

  ["sql"] = new CloudOnPremConn {
    onPrem = conn("sql_server")
    cloud = conn("azure_db_rw")
  }
  ["s3"] = new CloudOnPremConn {
    onPrem = conn("s3") |> s3("eyj0americasbucket02")
    cloud = conn("s3_polaris_cloud") |> s3("eyj0cloudamericabucket01")
  }
}

s3: CloudOnPremConn = new {
  onPrem = new S3 {
    conn_id = "s3"
    bucket = "eyj0americasbucket02"
  }
  cloud = new S3 {
    conn_id = "s3_polaris_cloud"
    bucket = "eyj0cloudamericabucket01"
  }
}

class CloudOnPremConn {
  onPrem: Conn
  cloud: Conn
}

class S3 extends Conn {
  bucket: String
}

You have a circular object that you are attempting to render. We should improve the error message here, although it's correct that it's throwing here.

Here's one circular path:

Conn.pkl -> s3 -> onPrem -> s3 -> onPrem -> s3 -> onPrem -> s3 -> ...

Somethings that can help you out is to separate your classes, so that s3 and connections are not properties of the Conn.

Here's one way to do it:

// Conn.pkl
open module Conn

import "Conn.pkl"

conn_id: String = ""

class CloudOnPremConn {
  onPrem: Conn?
  cloud: Conn?
}

class S3 extends Conn {
  bucket: String
}
// Connections.pkl
import "Conn.pkl"

connections: Mapping<String, Conn>

s3: Conn.CloudOnPremConn
// myConnections.pkl
amends "Connections.pkl"

import "Conn.pkl"

connections {
  default { key ->
    conn_id = "\(key)_cloud"
  }
  ["bento"] {}
  ["idp"] {}
  ["databricks"] {}
}

s3 {
  onPrem = new Conn.S3 {
    conn_id = "s3"
    bucket = "eyj0americasbucket02"
  }
  cloud = new Conn.S3 {
    conn_id = "s3_polaris_cloud"
    bucket = "eyj0cloudamericabucket01"
  }
}
