### Example Usage in a normal file

Source: https://github.com/d4l3k/messagediff/blob/master/README.md

Demonstrates how to use messagediff.PrettyDiff to compare two structs in a regular Go program.

```go
package main

import "gopkg.in/d4l3k/messagediff.v1"

type someStruct struct {
    A, b int
    C []int
}

func main() {
    a := someStruct{1, 2, []int{1}}
    b := someStruct{1, 3, []int{1, 2}}
    diff, equal := messagediff.PrettyDiff(a, b)
    /*
        diff =
        `added: .C[1] = 2
        modified: .b = 3`

        equal = false
    */
}
```

### Example Usage in a test

Source: https://github.com/d4l3k/messagediff/blob/master/README.md

Shows how to use messagediff.PrettyDiff within a Go test function to assert struct equality.

```go
import "gopkg.in/d4l3k/messagediff.v1"

...

type someStruct struct {
    A, b int
    C []int
}

func TestSomething(t *testing.T) {
    want := someStruct{1, 2, []int{1}}
    got := someStruct{1, 3, []int{1, 2}}
    if diff, equal := messagediff.PrettyDiff(want, got); !equal {
        t.Errorf("Something() = %#v\n%s", got, diff)
    }
}
```

### Ignoring a field in a struct

Source: https://github.com/d4l3k/messagediff/blob/master/README.md

Illustrates how to use the `testdiff:"ignore"` tag to exclude specific fields from the diff comparison.

```go
package main

import "gopkg.in/d4l3k/messagediff.v1"

type someStruct struct {
    A int
    B int `testdiff:"ignore"`
}

func main() {
    a := someStruct{1, 2}
    b := someStruct{1, 3}
    diff, equal := messagediff.PrettyDiff(a, b)
    /*
        equal = true
        diff = ""
    */
}
```
