![Gabs](gabs_logo.png "Gabs")
Gabs is a small utility for dealing with dynamic or unknown JSON structures in
golang. It's pretty much just a helpful wrapper around the golang
`json.Marshal/json.Unmarshal` behaviour and `map[string]interface{}` objects.
It does nothing spectacular except for being fabulous.
https://godoc.org/github.com/Jeffail/gabs
## How to install:
``` bash
go get github.com/Jeffail/gabs
```
## How to use
### Parsing and searching JSON
``` go
...
import "github.com/Jeffail/gabs"
jsonParsed, err := gabs.ParseJSON([]byte(`{
"outter":{
"inner":{
"value1":10,
"value2":22
},
"alsoInner":{
"value1":20
}
}
}`))
var value float64
var ok bool
value, ok = jsonParsed.Path("outter.inner.value1").Data().(float64)
// value == 10.0, ok == true
value, ok = jsonParsed.Search("outter", "inner", "value1").Data().(float64)
// value == 10.0, ok == true
value, ok = jsonParsed.Path("does.not.exist").Data().(float64)
// value == 0.0, ok == false
exists := jsonParsed.Exists("outter", "inner", "value1")
// exists == true
exists := jsonParsed.Exists("does", "not", "exist")
// exists == false
exists := jsonParsed.ExistsP("does.not.exist")
// exists == false
...
```
### Iterating objects
``` go
...
jsonParsed, _ := gabs.ParseJSON([]byte(`{"object":{ "first": 1, "second": 2, "third": 3 }}`))
// S is shorthand for Search
children, _ := jsonParsed.S("object").ChildrenMap()
for key, child := range children {
fmt.Printf("key: %v, value: %v\n", key, child.Data().(string))
}
...
```
### Iterating arrays
``` go
...
jsonParsed, _ := gabs.ParseJSON([]byte(`{"array":[ "first", "second", "third" ]}`))
// S is shorthand for Search
children, _ := jsonParsed.S("array").Children()
for _, child := range children {
fmt.Println(child.Data().(string))
}
...
```
Will print:
```
first
second
third
```
Children() will return all children of an array in order. This also works on
objects, however, the children will be returned in a random order.
### Searching through arrays
If your JSON structure contains arrays you can still search the fields of the
objects within the array, this returns a JSON array containing the results for
each element.
``` go
...
jsonParsed, _ := gabs.ParseJSON([]byte(`{"array":[ {"value":1}, {"value":2}, {"value":3} ]}`))
fmt.Println(jsonParsed.Path("array.value").String())
...
```
Will print:
```
[1,2,3]
```
### Generating JSON
``` go
...
jsonObj := gabs.New()
// or gabs.Consume(jsonObject) to work on an existing map[string]interface{}
jsonObj.Set(10, "outter", "inner", "value")
jsonObj.SetP(20, "outter.inner.value2")
jsonObj.Set(30, "outter", "inner2", "value3")
fmt.Println(jsonObj.String())
...
```
Will print:
```
{"outter":{"inner":{"value":10,"value2":20},"inner2":{"value3":30}}}
```
To pretty-print:
``` go
...
fmt.Println(jsonObj.StringIndent("", " "))
...
```
Will print:
```
{
"outter": {
"inner": {
"value": 10,
"value2": 20
},
"inner2": {
"value3": 30
}
}
}
```
### Generating Arrays
``` go
...
jsonObj := gabs.New()
jsonObj.Array("foo", "array")
// Or .ArrayP("foo.array")
jsonObj.ArrayAppend(10, "foo", "array")
jsonObj.ArrayAppend(20, "foo", "array")
jsonObj.ArrayAppend(30, "foo", "array")
fmt.Println(jsonObj.String())
...
```
Will print:
```
{"foo":{"array":[10,20,30]}}
```
Working with arrays by index:
``` go
...
jsonObj := gabs.New()
// Create an array with the length of 3
jsonObj.ArrayOfSize(3, "foo")
jsonObj.S("foo").SetIndex("test1", 0)
jsonObj.S("foo").SetIndex("test2", 1)
// Create an embedded array with the length of 3
jsonObj.S("foo").ArrayOfSizeI(3, 2)
jsonObj.S("foo").Index(2).SetIndex(1, 0)
jsonObj.S("foo").Index(2).SetIndex(2, 1)
jsonObj.S("foo").Index(2).SetIndex(3, 2)
fmt.Println(jsonObj.String())
...
```
Will print:
```
{"foo":["test1","test2",[1,2,3]]}
```
### Converting back to JSON
This is the easiest part:
``` go
...
jsonParsedObj, _ := gabs.ParseJSON([]byte(`{
"outter":{
"values":{
"first":10,
"second":11
}
},
"outter2":"hello world"
}`))
jsonOutput := jsonParsedObj.String()
// Becomes `{"outter":{"values":{"first":10,"second":11}},"outter2":"hello world"}`
...
```
And to serialize a specific segment is as simple as:
``` go
...
jsonParsedObj := gabs.ParseJSON([]byte(`{
"outter":{
"values":{
"first":10,
"second":11
}
},
"outter2":"hello world"
}`))
jsonOutput := jsonParsedObj.Search("outter").String()
// Becomes `{"values":{"first":10,"second":11}}`
...
```
### Merge two containers
You can merge a JSON structure into an existing one, where collisions will be
converted into a JSON array.
``` go
jsonParsed1, _ := ParseJSON([]byte(`{"outter": {"value1": "one"}}`))
jsonParsed2, _ := ParseJSON([]byte(`{"outter": {"inner": {"value3": "three"}}, "outter2": {"value2": "two"}}`))
jsonParsed1.Merge(jsonParsed2)
// Becomes `{"outter":{"inner":{"value3":"three"},"value1":"one"},"outter2":{"value2":"two"}}`
```
Arrays are merged:
``` go
jsonParsed1, _ := ParseJSON([]byte(`{"array": ["one"]}`))
jsonParsed2, _ := ParseJSON([]byte(`{"array": ["two"]}`))
jsonParsed1.Merge(jsonParsed2)
// Becomes `{"array":["one", "two"]}`
```
### Parsing Numbers
Gabs uses the `json` package under the bonnet, which by default will parse all
number values into `float64`. If you need to parse `Int` values then you should
use a `json.Decoder` (https://golang.org/pkg/encoding/json/#Decoder):
``` go
sample := []byte(`{"test":{"int":10, "float":6.66}}`)
dec := json.NewDecoder(bytes.NewReader(sample))
dec.UseNumber()
val, err := gabs.ParseJSONDecoder(dec)
if err != nil {
t.Errorf("Failed to parse: %v", err)
return
}
intValue, err := val.Path("test.int").Data().(json.Number).Int64()
```
