# JSON Merge Patch
|
||
|
|
|
||
|
|
The library supports JSON Merge Patch ([RFC 7386](https://tools.ietf.org/html/rfc7386)) as a patch format.
|
||
|
|
The merge patch format is primarily intended for use with the HTTP PATCH method as a means of describing a set of modifications to a target resource's content. This function applies a merge patch to the current JSON value.
|
||
|
|
|
||
|
|
Instead of using [JSON Pointer](json_pointer.md) to specify values to be manipulated, it describes the changes using a syntax that closely mimics the document being modified.
|
||
|
|
|
||
|
|
??? example
|
||
|
|
|
||
|
|
The following code shows how a JSON Merge Patch is applied to a JSON document.
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
--8<-- "examples/merge_patch.cpp"
|
||
|
|
```
|
||
|
|
|
||
|
|
Output:
|
||
|
|
|
||
|
|
```json
|
||
|
|
--8<-- "examples/merge_patch.output"
|
||
|
|
```
