Feature request: Querying Path

[omani]

Hi,

like in gjson:

name := gjson.Get(json, `programmers.#[lastName="Hunter"].firstName`)
println(name.String())  // prints "Elliotte"

It would be nice if one could set a field by querying for it. because right now I would like to update an object within an array. and I don't know the index beforehand.

any plans to implement this?

another approach would be to have a method on gjson to get the index of the found element (from above name's methods). then I could easily update via sjson by giving an index integer/string.

[omani]

just found out that there is a method for getting the index position. seems to be name.Int().

you can consider this issue as closed. but querying a path would be nice nevertheless.

Hi @omani,

I wrote the https://github.com/tidwall/sjson library that can be used for updating values. Though some paths, such as ones that have '#' character may not be updatable.

Sorry about the weird response. I thought this issue was filed on the gjson project.

This would be a pretty nice feature and something I'll keep in mind for a future release.

thanks for the quick response. yeah hope to see it sometime. the Int() method did the job for me for now.

thanks.

Glad to hear 👍

I realized method Int() is not the way to go here. new issue is tidwall/gjson#41.
