What would you like to do?
Printing structs; convert structs to JSON format easily.
// Printing structs.
package main
import (
type Arc struct {
Head string
Modifier string
func main() {
arc := Arc{"saw", "He"}
fmt.Printf("%v\n", arc)
fmt.Printf("%+v\n", arc)
fmt.Printf("%#v\n", arc)
// Convert structs to JSON.
data, err := json.Marshal(arc)
if err != nil {
fmt.Printf("%s\n", data)

Yes, that's what I ended up doing. The error I made was that Marshal has 2 return values and I embedded the return into a function, which Bob says is bad habit and shouldn't be done in Go. Once I made the call return two variables (to separate err), then Println didn't print the byte array.

Works without any extra effort (for private fields too).
