Fails to merge when using a pointer to a struct

[worg]

I don't seem to find out why the tests pass in stuff like complexTest but fails to merge correctly stuff like the following:

package main

import (
    "fmt"
    "github.com/imdario/mergo"
)

type Person struct {
    ID      int
    Name    string
    Address string
}

var defaultPerson = Person{
    ID:      1,
    Name:    "Homer",
    Address: "742 Evergreen Terrace",
}

func main() {
    a := Person{Name: `John`}
    if err := mergo.Merge(&a, defaultPerson); err != nil {
        fmt.Printf("ERR: %+v", err)
    }

    fmt.Printf("A is: %+v\n", a)
    // Prints A is: {ID:1 Name:Homer Address:742 Evergreen Terrace}
    // should print A is: {ID:1 Name:John Address:742 Evergreen Terrace}
}

I think function Merge means merge all no empty values in dest to src. so the example should like this:

func main() {
    a := defaultPerson
    if err := mergo.Merge(&a, Person{Name: `John`}); err != nil {
        fmt.Printf("ERR: %+v", err)
    }

    fmt.Printf("A is: %+v %v\n", a)
}

PS. i like the strategy merge when src‘s value is empty

Oh… I might have misunderstood, I wanted to merge all no empty values from src into dest, so closing this issue.
Thanks!

Thanks @lintianzhi for taking care of this issue. Merge works like you said 👍
