TJSON

The tolerant JSON parser and encoder for Haxe

TJSON is a project to create a JSON parser that is as tolerant as JavaScript is when it comes to JavaScript object notation, if not more error-tolerant. It supports all the current JSON standard, along with the following tollerances added:

1. Support single-quotes for strings
2. Keys don't have to be wrapped in quotes
3. C style comments support - /*comment*/
4. C++ style comments support - //comment
5. Dangling commas don't kill it (commas are even optional)

As of 1.1.0, TJSON also includes an encoder that encodes anonymous Haxe objects and arrays into JSON!

Usage

Install TJSON

Install via haxlib by running the following in your command line:

haxelib install tjson

Include TJSON in your build

Be sure to add the following to your .hxml file:

-lib tjson

Use in your code

Import TJSON class with:

import tjson.TJSON;

Then you can read JSON data with:

var jsonData = "{key:'value'}";
var object = TJSON.parse(jsonData);
trace(object.key); // outputs 'value'

It's that easy!

New in 1.1.0 - Encode Haxe objects into a JSON string with:

var objectToEncode={
	myKey:'myValue'
};
var json = TJSON.encode(objectToEncode);  // {"myKey":"myValue"}

The encoder currently supports two different encoding styles. The default is 'simple', which contains no whitespace. If you want more human-readable output, try the 'fancy' style:

var objectToEncode={
	myKey:'myValue'
};
var json = TJSON.encode(objectToEncode, 'fancy');
/*
{
	"myKey" : "myValue"
}
*/

Of course, the encoder can also encode arrays:

var myArray = [1,32,43,54];
var json = TJSON.encode(myArray);

New in 1.3.0 - Class objects can now be serialized and unserialized with TJSON!

TJSON will add a '_hxcls' key to the serialized JSON code so it know what class it came from.

New in 1.4.0 - Class object serialization features

If a class object being unserialized has a function named 'TJ_unserialize', it will be called after the object is unserialized.

You can specify properties that should not be serialized by defining a function called 'TJ_noEncode' that returns an array of property names not to serialize.

In this example, TJSON will skip the property called 'dontSerialize':

public function TJ_noEncode():Array<String>{
	return ['dontSerialize'];
}
