JSON parser

A functional json parser written using monadic parser combinators

Currently it does not support exponential numbers and string escape characters

Gleam JSON type

Json is parsed using the following JsonValue type

pub type JsonValue {
  JsonNull
  JsonBool(Bool)
  JsonNumber(Float)
  JsonString(String)
  JsonArray(List(JsonValue))
  JsonObject(List(#(String, JsonValue)))
}

Example

Parses this json

{
  "age": 12.123,
  "name": "Eric Cartman",
  "favourite color": "red",
  "cars": [
    "toyota prius 2004",
    "Hot dog",
    {
      "x": false
    }
  ]
}

into this gleam expression

#([], JsonObject([#("age", JsonNumber(12.123)), #("name", JsonString("Eric Cartman")), #("favourite color", JsonString("red")), #("cars", JsonArray([JsonString("toyota prius 2004"), JsonString("Hot dog"), JsonObject([#("x", JsonBool(False))])]))]))
