Yaml Parser Support

[sai-koushik-macha]

So, will there be support for the yaml parser just like json parser. The requirement I am using json parser for reading purpose by reading json file and after reading I think it interally converts it into ptree. So, is it possible to do same with yaml

#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/yaml_parser.hpp>
#include <iostream>
#include <fstream>

int main() {
    try {
        // Create a property tree
        boost::property_tree::ptree pt;

        // Read YAML from a file
        std::ifstream yaml_input("input.yaml");
        if (!yaml_input) {
            throw std::runtime_error("Failed to open input.yaml");
        }
        boost::property_tree::read_yaml(yaml_input, pt);

        // Access and print data from the YAML file
        std::cout << "Name: " << pt.get<std::string>("name") << std::endl;
        std::cout << "Age: " << pt.get<int>("age") << std::endl;
        std::cout << "Address: " << pt.get<std::string>("address.city") << ", " << pt.get<std::string>("address.state") << std::endl;

        // Modify the property tree
        pt.put("age", 31); // Update age
        pt.put("address.zip", "12345"); // Add a new field

        // Write the modified property tree to a new YAML file
        std::ofstream yaml_output("output.yaml");
        if (!yaml_output) {
            throw std::runtime_error("Failed to open output.yaml");
        }
        boost::property_tree::write_yaml(yaml_output, pt);

        std::cout << "Modified YAML written to output.yaml" << std::endl;
    } catch (const std::exception& e) {
        std::cerr << "Error: " << e.what() << std::endl;
    }

    return 0;
}
