How to generate a range of “int“

[mNantern]

Hello 👋.

I'm trying to convert Spinnaker pipelines definition (which are giant json) to CUE and it's going great.

One think that I don't know how to do yet is generate a field called refId which is an int disguised in a string (??) and that represent the position of the object in a list:

{
  "stages": [
    {
     …
      "refId": "1"
     …
    },
    {
      …
      "refId": "2"
      …
    },
    {
      …
      "refId": "3"
      …
    }
  ]
}

My questions are:

1. Is there a way to do it more cleanly with Cue?
2. I also need to generate a list of refId: requisiteStageRefIds: ["21", "22", "23", "24", "25", "26", "27", "28"]. Anything that I can do generate a range of int ?

Thank you 🙏

There is the list.Range function. You can then use strconv.FormatInt to project the integers to strings.

I should have looked at the function, thank you it's working great 🙏

If you already have your objects in a list, you can unify the id into the object after string interpolation, in a list comprehension

refd: [ for i, obj in objs { obj & { refId: "\(i)" } }]

Use refId: "\(i+1)" if you want to start indexing at 1
