@fromstr doesn't appear to work

[lsh-0]

Using https://gjson.dev, an input of:

name.last

yields

"Anderson"

and I would expect using the modifier @fromstr like:

name.last|@fromstr

to yield:

Anderson

(without quotes), instead nothing is displayed.

Locally the extracted_value.Exists() is returning false.

Am I using @fromstr correctly? I've also tried some.path.@fromstr as well downgrading to gjson@1.16.0 with the same results.

Thanks,

The @fromstr modifier is used to unescape json that is stored in a string.

Using the path person.@fromstr.last with json

{"person":"{\"last\":\"Anderson\"}"}

returns "Anderson".

[lsh-0]

ah ... so is there an equivalent to jq --raw-output that would let me get at the string Anderson without quotes?

[tidwall]

gjson.Get("name.last").String()

[lsh-0]

Unfortunately the path is passed in by the user, much like https://gjson.dev

@fromstr: Converts a string from json. Unwraps a json string.

It sounds like what I need but I was mistaken. Thanks for your time.

No problem, glad you found a solution.
