使用YAML-CPP将YAML发射器内容保存到文件中

git clone https://github.com/jbeder/yaml-cpp.git
cd yaml-cpp
mkdir build
cd build
cmake ..
make
sudo make install

#include<iostream>
#include <fstream>
#include <yaml-cpp/yaml.h>

int main() {
    // 创建YAML发射器
    YAML::Emitter out;
    out << YAML::BeginMap;
    out << YAML::Key << "name" << YAML::Value << "John Smith";
    out << YAML::Key << "age" << YAML::Value << 30;
    out << YAML::EndMap;

    // 将YAML发射器内容保存到文件中
    std::ofstream fout("output.yaml");
    fout<< out.c_str();
    fout.close();

    return 0;
}

g++ main.cpp -o main -lyaml-cpp

./main

cat output.yaml
