9721,ptree write_json does not conform to JSON standard,Mark Pfeifer <Mark_Pfeifer@…>,Sebastian Redl,"According to the JSON standard documented at http://www.json.org, only string values should have quotes around them.  The Boost write_json method puts quotes around all values, not just strings.

For example, the following program:

#include <cstdlib>
#include <string>
#include <iostream>
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/json_parser.hpp>

using boost::property_tree::ptree;
using boost::property_tree::read_json;
using boost::property_tree::write_json;

int main()
{
    ptree pt;
    
    pt.put (""string"", ""string value"");
    pt.put (""integer"", 1);
    pt.put (""float"", 3.14159);

    std::ostringstream buf; 
    write_json (buf, pt);

    std::cout << buf.str();
    return 0;
}

produces this output:

{
    ""string"": ""string value"",
    ""integer"": ""1"",
    ""float"": ""3.14159""
}

According to the JSON standard, the output should be:

{
    ""string"": ""string value"",
    ""integer"": 1,
    ""float"": 3.14159
}
