YAML开源库yaml-cpp简介及使⽤解析和产⽣yaml⽂件的测试代码如下：
#include "funt.hpp"
#include <string>
#include <fstream>
#include <yaml-cpp/yaml.h>
int test_par_yaml_file()
{
#ifdef _MSC_VER

int test_generate_yaml_file()

node["url"].push_back("/fengbingchun");what about now
node["url"].push_back("/fengbingchun");

primes.push_back(13);

YAML::Node lineup = YAML::Load("{1B: Prince Fielder, 2B: Rickie Weeks, LF: Ryan Braun}"); lineup["RF"] = "Corey Hart";
lineup["C"] = "Jonathan Lucroy";
node["name"] = lineup;
node["platform"]["linux"].push_back("x86");款式的英文
node["platform"]["linux"].push_back("x86_64");
node["platform"]["linux"].push_back("armv7");
node["platform"]["windows"].push_back("x86");
node["platform"]["windows"].push_back("x86_64");

解析yaml⽂件输出结果如下：
产⽣yaml⽂件的内容如下：
