How to print struct variables in console?

To print the name of the fields in a struct:

fmt.Printf("%+v\n", yourProject)

From the fmt package:

when printing structs, the plus flag (%+v) adds field names

That supposes you have an instance of Project (in ‘yourProject‘)

The article JSON and Go will give more details on how to retrieve the values from a JSON struct.

This Go by example page provides another technique:

type Response2 struct {
  Page   int      `json:"page"`
  Fruits []string `json:"fruits"`
}

res2D := &Response2{
    Page:   1,
    Fruits: []string{"apple", "peach", "pear"}}
res2B, _ := json.Marshal(res2D)
fmt.Println(string(res2B))

That would print:

{"page":1,"fruits":["apple","peach","pear"]}

If you don’t have any instance, then you need to use reflection to display the name of the field of a given struct, as in this example.

type T struct {
    A int
    B string
}

t := T{23, "skidoo"}
s := reflect.ValueOf(&t).Elem()
typeOfT := s.Type()

for i := 0; i < s.NumField(); i++ {
    f := s.Field(i)
    fmt.Printf("%d: %s %s = %v\n", i,
        typeOfT.Field(i).Name, f.Type(), f.Interface())
}
