Update of nested array objects identified with # is not working

[samybenatt]

Hello,

Here is a sample program illustrating the issue:

package main

import "github.com/tidwall/sjson"

const json = `{"object1":{"object2":[{"nested_object1":{"nested_object2":[{"nested2_object1":1},{"nested2_object1":1}]}}]}}`

func main() {
	value, _ := sjson.Set(json, "object1.object2.#.nested_object1.nested_object2.#.nested2_object1", 2)
	println("updated all nested arrays objects with # identifier: ", value)
	value2, _ := sjson.Set(json, "object1.object2.#.nested_object1.nested_object2.0.nested2_object1", 2)
	value3, _ := sjson.Set(value2, "object1.object2.#.nested_object1.nested_object2.1.nested2_object1", 2)
	println("updated nested arrays with index identifier, one by one: ", value3)
}

Output:

updated all nested arrays objects with # identifier:  2ect1":{"object2":[{"nested_object1":{"nested_object2":[{"nested2_object1":1},{"nested2_object1":1}]}}]}}
updated nested arrays with index identifier, one by one:  {"object1":{"object2":[{"nested_object1":{"nested_object2":[{"nested2_object1":2},{"nested2_object1":2}]}}]}}

As we can see, when I try to update the same property of nested array's objects, it is not able to do it
But when I do it one by one, by identifying the index properly, it works

Anything I'm doing wrong ?

Basically, for this kind of expression, sjson is based on gjson for parsing. For gjson, nested # expressions will result in a nested array, which causes sjson to have difficulty finding the correct index to start the replacement.

I am working on a solution, which seems feasible so far, but I am still studying the sjson source code to ensure my fix is correct.
