ZIO HTTP Doesn't Respect Bash Naming Style (Environment Variables)

[khajavi]

Assume I have the following ZIO HTTP App:

object MainApp extends ZIOAppDefault {
  def run =
    Server.serve(
      Routes(
        Method.GET / "hello" -> handler(Response.ok),
      ),
    ).provide(
      Server.live,
      ZLayer.fromZIO(ZIO.config(Server.Config.config)).debug)
    )
}

If of set:

export BINDING_PORT=3000

But it doesn't respect it and after debugging find out that it requires BINDING-PORT

The workaround is to map key names using Server.Config.config.mapKey(_.replace('-', '_')) which is not idiomatic.
