| # 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" |
| ``` |
