Applying mixins in ln for generator

[sergeyshevch]

Hi! We're experimenting with pkl for our setup and want to apply mixins in for loop.

//groups/1.pkl
service: Mixin<main.Service> = new {
  configs {
    resources {
      requests {
        ["cpu"] = 1
        ["memory"] = "1024Mi"
      }
    }
  }
}

// configs/test.pkl
groups = new Listing {
  "1"
  "2"
}

// main.pkl
groups = import*("groups/*.pkl")
services = import*("configs/*.pkl").toMap().map((name, service) -> Pair(name, new Listing{
  for (group in service.groups) {
    (service.service) |> groupConfigs["groups/" + group + ".pkl"].service
  }
})
)

In this case we want to apply both mixins in order that defined in groups. Is it possible somehow? Current main code doesn't work correctly

If I'm interpreting your question correctly, it seems like you're trying to iteratively apply multiple mixins to the same base value in a specific order. If that is the case, I think what you want to use here is fold:

services = import*("configs/*.pkl").toMap().map((name, service) -> Pair(
  name,
  service.groups.fold(service.service, (acc, groupName) ->
    acc |> groupConfigs["groups/" + groupName + ".pkl"].service
  )
))

If this isn't what you're going for, can you clarify a little more what your desired output is here?

Great! This is exactly what I looked for. Thanks for your answer!
