<p align="center">get json values quickly</a></p>
GJSON is a Go package that provides a [fast](#performance) and [simple](#get-a-value) way to get values from a json document.
It has features such as [one line retrieval](#get-a-value), [dot notation paths](#path-syntax), [iteration](#iterate-through-an-object-or-array).
It has features such as [one line retrieval](#get-a-value), [dot notation paths](#path-syntax), [iteration](#iterate-through-an-object-or-array), and [parsing json lines](#json-lines).
Also check out [SJSON](https://github.com/tidwall/sjson) for modifying json, and the [JJ](https://github.com/tidwall/jj) command line tool.

## Get a value
Get searches json for the specified path. A path is in dot syntax, such as "name.last" or "age". This function expects that the json is well-formed. Bad json will not panic, but it may return back unexpected results. When the value is found it's returned immediately.

friends.#[first%"D*"].last >> "Murphy"
```
## JSON Lines
There's support for [JSON Lines](http://jsonlines.org/) using the `..` prefix, which treats a multilined document as an array.
For example:
```
{"name": "Gilbert", "age": 61}
{"name": "Alexa", "age": 34}
{"name": "May", "age": 57}
{"name": "Deloise", "age": 44}
```
```
..# >> 4
..1 >> {"name": "Alexa", "age": 34}
..3 >> {"name": "Deloise", "age": 44}
..#.name >> ["Gilbert","Alexa","May","Deloise"]
..#[name="May"].age >> 57
```
The `ForEachLines` function will iterate through JSON lines.
```go
gjson.ForEachLine(json, func(line gjson.Result) bool{
println(line.String())
return true
})
```
## Result Type
GJSON supports the json types `string`, `number`, `bool`, and `null`.

### 64-bit integers
The `result.Int()` and `result.Uint()` calls are capable of reading all 64 bits, allowing for large JSON integers.
```go
result.Int() int64 // -9223372036854775808 to 9223372036854775807
result.Uint() int64 // 0 to 18446744073709551615

Suppose you want all the last names from the following json:
@ -234,51 +275,17 @@ if gjson.Get(json, "name.last").Exists() {
}
```
## Unmarshalling
## Validate JSON
There's a `gjson.Unmarshal` function which loads json data into a value.
It's a general replacement for `json.Unmarshal` and you can typically
see a 2-3x boost in performance without the need for external generators.
This function works almost identically to `json.Unmarshal` except that
`gjson.Unmarshal` will automatically attempt to convert JSON values to any
Go type. For example, the JSON string "100" or the JSON number 100 can be
equally assigned to Go string, int, byte, uint64, etc. This rule applies to
all types.
The `Get*` and `Parse*` functions expects that the json is well-formed. Bad json will not panic, but it may return back unexpected results.
If you are consuming JSON from an unpredictable source then you may want to validate prior to using GJSON.
```go
package main
import (
"fmt"
"github.com/tidwall/gjson"
)
type Animal struct {
Type string `json:"type"`
Sound string `json:"sound"`
Age int `json:"age"`
if !gjson.Valid(json) {
return errors.New("invalid json")
}
var json = `{
"type": "Dog",
"Sound": "Bark",
"Age": "11"
}`
func main() {
var dog Animal
gjson.Unmarshal([]byte(json), &dog)
fmt.Printf("type: %s, sound: %s, age: %d\n", dog.Type, dog.Sound, dog.Age)
}
```
This will print:
```
type: Dog, sound: Bark, age: 11
value := gjson.Get(json, "name.last")
```

<p align="center">set a json value quickly</p>
SJSON is a Go package that provides a [very fast](#performance) and simple way to set a value in a json document. The purpose for this library is to provide efficient json updating for the [SummitDB](https://github.com/tidwall/summitdb) project.
For quickly retrieving json values check out [GJSON](https://github.com/tidwall/gjson).
For a command line interface check out [JSONed](https://github.com/tidwall/jsoned).
For a command line interface check out [JJ](https://github.com/tidwall/jj).
