A Go library to recursively visit data structures using reflection.

```go

import "github.com/keilerkonzept/visit"

```

## Get it

```sh

go get -u "github.com/keilerkonzept/visit"

```

## Use it

```go

import (

    "github.com/keilerkonzept/visit"

    "fmt"

    "reflect"

)

type myStruct struct {

    String string

    Map    map[string]myStruct

    Ptr    *myStruct

}

func main() {

	obj := &myStruct{

		String: "hello",

		Map: map[string]myStruct{

			"world": myStruct{String: "!"},

		},

	}

	obj.Ptr = obj

	var strings []string

	visit.Values(obj, func(value visit.ValueWithParent) (visit.Action, error) {

		if value.Kind() == reflect.String {

			strings = append(strings, value.String())

		}

		return visit.Continue, nil

	})

	fmt.Println(strings)

	// Output:

	// [hello world !]

}

```
