Golang multiple json tag names for one field

Question

It it possible in Golang to use more than one name for a JSON struct tag ?

type Animation struct {
    Name    string  `json:\"name\"`
    Repeat  int     `json:

See How to define multiple name tags in a struct on how you can define multiple tags on one struct field.

You can also use a type Info map[string]interface{} instead of your struct.

Or you can use both types in your structure, and make method Details() which will return right pattern.

type Animation struct {
    Name    string  `json:"name"`
    Repeat  int     `json:"repeat"`
    Speed   uint    `json:"speed"`
    Pattern Pattern `json:"pattern"`
    Frame   Pattern `json:"frames"`
}

func (a Animation) Details() Pattern {
    if a.Pattern == nil {
        return a.Frame
    }
    return a.Pattern
}
