I am getting this compilation error with g++. And my main.cpp is the example for this link: http://code.google.com/p/jzon/wiki/WritingFiles

My g++ version output is:

macbook-pro:Jzon v2-0 will$ g++ --version
i686-apple-darwin11-llvm-g++-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

Please fix it, a lot of stuff are missing now. Getting a lot of errors.

I'm having a JSON like below
{ "String1":"Hello", "Array1":[ [0.1, 0.2, 0.3], [0.4, 0.5, 0.6], [0.7, 0.8, 0.9] ], "Array2":[ [0.7, 0.8, 0.9], [0.1, 0.2, 0.3], [0.4, 0.5, 0.6] ] }
How do I get Array1 & Array2 out of this JSON and store it?

Some characters should be escaped before being written, for example the " character.

https://github.com/miloyip/nativejson-benchmark/blob/master/sample/conformance_Jzon%20(C%2B%2B).md

Add missing getter for unsigned long long and long long, in "ToXXX" family of methods.
Currently there are none, i had to manually add them

Hi, I would like to read a nested json structure like this one:

{
 "Observer" : [ 
 "x" : 8.3, 
 "y" : 0.0 ],
 "Grid" : [
 "a" : 0,
 "b" : "test" ]
}

The following code can read the values (e.g., 8.3, 0) but not the names associated (x, y):

const Jzon::Array &stuff = rootNode.Get("Observer").AsArray();
for (Jzon::Array::const_iterator it = stuff.begin(); it != stuff.end(); ++it)
{
   std::cout << (*it).ToString() << std::endl;
}

Can you suggest me an alternative way of doing it?

Add a way to handle errors from the parser when trying to parse an invalid file.

just made simple main file got lots of compilations errors:

include "Jzon.h"

int main(int argc,char** argv[])
{

Jzon::Object rootNode;
if(Jzon::FileReader::ReadFile("d:\\dev\\SVN_client\\trunk\\google.code.projects\\FB_GraphApi_v2\\ping_group_result31.12.2012.json", rootNode))
{

}
else
{
    cout << "Unable to open file"; 
}




return 0;

}

Jzon currently only supports plain ASCII data.

Add support for more encodings (UTF-8, etc..).

the code

Jzon::Node array = Jzon::array();
....
Jzon::Node::const_iterator it = array.begin();

gave me the error

conversion from `Jzon::Node::iterator` to non-scalar type `Jzon::Node::const_iterator` requested

I assume this is just an accident?
