Nim: Object to JSON

Mar 21, 2022

Turning a data structure into JSON is incredibly easy in Nim:

import json

  Person = object
    first: string
    last: string

var p = Person(first: "Glenn", last: "Gillen")

Where the % macro/operator is shorthand from the json module for converting to JSON. There's also the %* macro which can be used for assigning an object directly into a JSON data structure:

import json
let obj = %* { "first_name": "glenn", "last_name": "gillen" }
echo $obj
