Does not parse array json

[albassort]

This is valid json:

[
	["a", "b", "c"]
]

however, jsony cant parse it.

import jsony
type abc = object
    a : string
    b : string
    c : string
let s = "[["a", "b", "c"]]"
let v = s.fromJson(abc)
echo v

however, this library wasn't made with the json spec in mind.

This should return an array of abc.

Your object does not match the json you want to parse.

You can can do this if you want to keep the json the same:

let s = """[["a", "b", "c"]]"""
echo s.fromJson(seq[seq[string]])

Or this if you want to keep the object the same:

type abc = object
    a : string
    b : string
    c : string
let s2 = """{"a":"something", "b":"otherthing", "c":"yes"}"""
echo s2.fromJson(abc)

or if you want an array of abc object use this:

let s3 = """[{"a":"something", "b":"otherthing", "c":"yes"}]"""
echo s3.fromJson(seq[abc])

I hope that helps!

Oh and you can also use a parse hook to parse your original json into your object... but its a more advanced thing, you probably don't need that:

proc parseHook*(s: string, i: var int, v: var abc) =
  var arr: seq[string]
  parseHook(s, i, arr)
  v = abc()
  v.a = arr[0]
  v.b = arr[1]
  v.c = arr[2]

let s = """[["a", "b", "c"]]"""
echo s.fromJson(seq[abc])
