iter-json

This tool is designed for iterating over a large (and probably unstructured) JSON files.
It is useful for processing JSON files that are too large to fit into memory.

Example

package main

import (
	"fmt"
	"github.com/botsman/iter-json"
	"strings"
)

func main() {
	iter := iter_json.NewIterator()
	val := `{"a": 1, "b": 2, "c": 3, "d": [1, 2, 3], "e": {"f": {"g": 4}}}`
	ch, err := iter.Iterate(strings.NewReader(val))
	if err != nil {
		panic(err)
	}
	for e := range ch {
		fmt.Println(e.PathString(), e.Val)
	}
}

Output:

a 1
b 2
c 3
d.0 1
d.1 2
d.2 3
e.f.g 4

Interface:
After creating an iterator (NewIterator()), you can iterate over a JSON string by calling Iterate() method.
It returns a channel of Entry objects:

type PathKind int

const (
    _ PathKind = iota
    OBJECT
    ARRAY
)

type JsonPathElement struct {
    Kind PathKind
    Key  interface{}
}

type JsonEntry struct {
    Path []JsonPathElement
    Val  interface{}
}
