# Go JSON Diff (and Patch)

[godoc]: https://godoc.org/github.com/yudai/gojsondiff
[license]: https://github.com/yudai/gojsondiff/blob/master/LICENSE
## How to use
### Installation
```sh
go get github.com/yudai/gojsondiff
```
### Comparing two JSON strings
See `jd/main.go` for how to use this library.
## CLI tool
This repository contains a package that you can use as a CLI tool.
### Installation
```sh
go get github.com/yudai/gojsondiff/jd
```
### Usage
#### Diff
Just give two json files to the `jd` command:
```sh
jd one.json another.json
```
Outputs would be something like:
```diff
{
"arr": [
0: "arr0",
1: 21,
2: {
"num": 1,
- "str": "pek3f"
+ "str": "changed"
},
3: [
0: 0,
- 1: "1"
+ 1: "changed"
]
],
"bool": true,
"num_float": 39.39,
"num_int": 13,
"obj": {
"arr": [
0: 17,
1: "str",
2: {
- "str": "eafeb"
+ "str": "changed"
}
],
+ "new": "added",
- "num": 19,
"obj": {
- "num": 14,
+ "num": 9999
- "str": "efj3"
+ "str": "changed"
},
"str": "bcded"
},
"str": "abcde"
}
```
When you prefer the delta format of [jsondiffpatch](https://github.com/benjamine/jsondiffpatch), add the `-f delta` option.
```sh
jd -f delta one.json another.json
```
This command shows:
```json
{
"arr": {
"2": {
"str": [
"pek3f",
"changed"
]
},
"3": {
"1": [
"1",
"changed"
],
"_t": "a"
},
"_t": "a"
},
"obj": {
"arr": {
"2": {
"str": [
"eafeb",
"changed"
]
},
"_t": "a"
},
"new": [
"added"
],
"num": [
19,
0,
0
],
"obj": {
"num": [
14,
9999
],
"str": [
"efj3",
"changed"
]
}
}
}
```
#### Patch
Give a diff file in the delta format and the JSON file to the `jp` command.
```sh
jp diff.delta one.json
```
