Golang map field

Primitive support in Golang is standard as bool and bool? emi types. bool resolves the primitive counterpart in golang without modification, whearas the nullable data types such as bool? will be wrapped around Nullable[bool] similar to all other primitives and structs which are nullable.

Emi doesn’t generate pointer elements in Golang, and it’s support has been removed many years ago in Fireback.

name: Catalog
fields:
  - name: personConfig
    type: map
    mapKeyOf: string
    mapPairOf: any
  - name: personConfigExtra
    type: map?
    mapKeyOf: string
    mapPairOf: any

Possible result:

package datatypes

import "encoding/json"

func GetCatalogCliFlags(prefix string) []emigo.CliFlag {
  return []emigo.CliFlag{
    {
      Name: prefix + "person-config",
      Type: "map",
    },
    {
      Name: prefix + "person-config-extra",
      Type: "map?",
    },
  }
}
func CastCatalogFromCli(c emigo.CliCastable) Catalog {
  data := Catalog{}
  if c.IsSet("person-config-extra") {
    emigo.ParseNullable(c.String("person-config-extra"), &data.PersonConfigExtra)
  }
  return data
}

// The base class definition for catalog

  PersonConfigExtra emigo.Nullable[map[string]any] `json:"personConfigExtra" yaml:"personConfigExtra"`
}

func (x *Catalog) Json() string {
  if x != nil {
    str, _ := json.MarshalIndent(x, "", "  ")
