Szathmáry László honlapja @ DEIK | Nim2 / JSON: read a dictionary

We want to work with the following file:

{
"last": "Doe",
"first": "John",
"age": 39,
"sex": "M",
"registered": true,
"salary": 70000,
"daughter": {
"last": "Doe",
"first": "Jane",
"age": 18,
"sex": "F"
}
}

import std/json

proc main() =
let
fname = "person.json"
parsed = parseFile(fname)

for key, val in parsed.pairs():
echo key, " -> ", val

echo "---"

echo parsed["age"].to(int)
echo "daughter" in parsed
echo parsed["daughter"]["age"].to(int)

main()

Output:

last -> "Doe"
first -> "John"
age -> 39
sex -> "M"
registered -> true
salary -> 70000
daughter -> {"last":"Doe","first":"Jane","age":18,"sex":"F"}
