Provides two methods: json2list() and list2json().

For more information, see the Wikipedia article:

JSON is a lightweight text-based open standard designed for human-readable data interchange. It is derived from the JavaScript programming language for representing simple data structures and associative arrays, called objects. Despite its relationship to JavaScript, it is language-independent, with parsers available for most programming languages.

Hi hello, just for posterity it's worth mentioning that this forms improper JSON strings.

For list: foo=bar
It will produce: {foo:"bar"}
This is missing the double quotes around the key (foo).

You can fix it by just modifying WriteObject() in JSON Writer.dm (put quotes around [k]).

Good job I guess.

Actually, there's a more direct way of doing this. You should be able to create a new /json_reader and use it to parse any value. I haven't tested this code, but it should work.

proc/get_value(json)
  var/json_reader/reader = new()
  reader.tokens = reader.ScanJson(json)
  reader.i = 1
  return reader.read_value()

Where json is any value: an array, a number, an object, a string, true, false, or null. This is not the way the library is meant to be used, so I will probably add better support for what you're trying to do in the future.

Ok, I'll look at it again today. There are some other changes I'd need to make too, but I can probably get it working without having to change your library. All this to avoid writing my own parser =)

Not really, though you could just add the array to an object and then parse that:

var/array = "\[1,2,3]"
var/list/result = json2list("{array:[array]}")
for(var/number in result["array"])
  world<<number

I haven't look through the code too much, but is there an easy way to parse any JS data? I don't want to parse objects all the time, sometimes I just want to parse an array.
