# flatted (Go)
|
|
|
|
A super light and fast circular JSON parser.
|
|
|
|
## Usage
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"github.com/WebReflection/flatted/golang/pkg/flatted"
|
|
)
|
|
|
|
type Group struct {
|
|
Name string `json:"name"`
|
|
}
|
|
|
|
type User struct {
|
|
Name string `json:"name"`
|
|
Friend *User `json:"friend"`
|
|
Group *Group `json:"group"`
|
|
}
|
|
|
|
func main() {
|
|
group := &Group{Name: "Developers"}
|
|
alice := &User{Name: "Alice", Group: group}
|
|
bob := &User{Name: "Bob", Group: group}
|
|
|
|
alice.Friend = bob
|
|
bob.Friend = alice // Circular reference
|
|
|
|
// Stringify Alice
|
|
s, _ := flatted.Stringify(alice)
|
|
fmt.Println(s)
|
|
// Output: [{"name":"Alice","friend":"1","group":"2"},{"name":"Bob","friend":"0","group":"2"},{"name":"Developers"}]
|
|
|
|
// Flattening in action:
|
|
// Index "0" is Alice, Index "1" is Bob, Index "2" is the shared Group.
|
|
|
|
// Parse back into a generic map structure
|
|
res, _ := flatted.Parse(s)
|
|
aliceMap := res.(map[string]any)
|
|
fmt.Println(aliceMap["name"]) // Alice
|
|
}
|
|
```
|
|
|
|
## CLI
|
|
|
|
Build the binary using the provided Makefile:
|
|
|
|
```bash
|
|
make build
|
|
```
|
|
|
|
Then use it to parse flatted JSON from stdin:
|
|
|
|
```bash
|
|
echo '[{"a":"1"},"b"]' | ./flatted
|
|
```
