# jsonpointer

golang implementation of [IETF RFC6901](https://tools.ietf.org/html/rfc6901):

_JSON Pointer defines a string syntax for identifying a specific value within a JavaScript Object Notation (JSON) document._

### Installation

install with:

`go get -u github.com/qri-io/jsonpointer`

### Usage

Here's a quick example pulled from the [godoc](https://godoc.org/github.com/qri-io/jsonpointer):

```go

import (

  "encoding/json"

  "fmt"

  "github.com/qri-io/jsonpointer"

)

var document = []byte(`{ 

  "foo": {

    "bar": {

      "baz": [0,"hello!"]

    }

  }

}`)

func main() {

  parsed := map[string]interface{}{}

  // be sure to handle errors in real-world code!

  json.Unmarshal(document, &parsed)

  // parse a json pointer. Pointers can also be url fragments

  // the following are equivelent pointers:

  // "/foo/bar/baz/1"

  // "#/foo/bar/baz/1"

  // "http://example.com/document.json#/foo/bar/baz/1"

  ptr, _ := jsonpointer.Parse("/foo/bar/baz/1")

  // evaluate the pointer against the document

  // evaluation always starts at the root of the document

  got, _ := ptr.Eval(parsed)

  fmt.Println(got)

  // Output: hello!

}

```
