Print all properties of struct even through that struct has a default string representation?

Question

Normally, I can print all properties of an object with:

c.Infof("car: %+v", car)

But one struct has a String() method. I think that this causes the line above to only print what the String() method returns.

How can I override this and force print all properties of that struct?

Please, what are you trying to achieve exactly ? The question is unclear actually. — T. Claverie, May 31 '16 at 15:25
I didnt know it would be so unclear. Ill post it tomorrow, when Im at my computer again — user1283776, May 31 '16 at 15:38

An easy workaround is to use the %#v verb:

package main

import (
    "fmt"
)

type someStruct struct {
    a int
    b int
}

func (someStruct) String() string {
    return "this is the end"
}

func main() {
    fmt.Printf("%+v\n", someStruct{1, 2})
    fmt.Printf("%#v\n", someStruct{1, 2})
}

This prints:

this is the end
main.someStruct{a:1, b:2}

@RickyA: it helps to read through the [`fmt` documentation:](https://golang.org/pkg/fmt/) `%#v a Go-syntax representation of the value`. (note that `%#v` is also modifiable via the GoStringer interface) – JimB May 31 '16 at 15:41
