## Status

API is stable.

## Import this library in your project

```cmd
go get github.com/go-openapi/jsonpointer
```

## Basic usage

See also some [examples](./examples_test.go)

### Retrieving a value

```go
  import (
    "github.com/go-openapi/jsonpointer"
  )


  var doc any

  ...

	pointer, err := jsonpointer.New("/foo/1")
	if err != nil {
		... // error: e.g. invalid JSON pointer specification
	}

	value, kind, err := pointer.Get(doc)
	if err != nil {
		... // error: e.g. key not found, index out of bounds, etc.
	}

  ...
```

### Setting a value

```go
  ...
  var doc any
  ...
	pointer, err := jsonpointer.New("/foo/1")
	if err != nil {
		... // error: e.g. invalid JSON pointer specification
  }

	doc, err = p.Set(doc, "value")
	if err != nil {
		... // error: e.g. key not found, index out of bounds, etc.
	}
```

## Change log

See <https://github.com/go-openapi/jsonpointer/releases>

## References

<https://tools.ietf.org/html/draft-ietf-appsawg-json-pointer-07>

also known as [RFC6901](https://www.rfc-editor.org/rfc/rfc6901)

## Licensing

This library ships under the [SPDX-License-Identifier: Apache-2.0](./LICENSE).

See the license [NOTICE](./NOTICE), which recalls the licensing terms of all the pieces of software
on top of which it has been built.

## Limitations

The 4.Evaluation part of the previous reference, starting with 'If the currently referenced value is a JSON array,
the reference token MUST contain either...' is not implemented.

That is because our implementation of the JSON pointer only supports explicit references to array elements:
the provision in the spec to resolve non-existent members as "the last element in the array",
using the special trailing character "-" is not implemented.
