If i want to *read *just a certain part of a json file, i create my struct
and unmarshall the json data. It works wonderfully.
But what if i want to *modify *a certain part of the json file and save my
changes, of course i don't want other parts to be lost. Consider this json;
{
"this_i_want_to_modify": *100*,
"this_i_dont_even_know_about": {
"some_field": "data",
"some_other": "da_ta"
}
}
Sure i can create the necessary structures for the whole json in Go and
unmarshall-edit-marshall, but i am not the maintainer of this json file.
There can be new fields tomorrow and if i don't update my code, my
unmarshall-marshall will delete those new fields.
Is there an idiomatic way to accomplish this? Thanks.
