使用C++的inipp库处理配置文件.ini的示例详解

[Database]
Host = localhost
Port = 3306
Username = myuser
Password = mypassword

[AppSettings]
LogLevel = 2
MaxConnections = 10

#include "inipp.h"
#include <fstream>
#include <string>

int main()
{
    inipp::Ini<char> ini;
    std::ifstream is("config.ini");
    if (!is) {
        std::cerr << "error: open config.ini failed" << std::endl;
        return 1;
    }
    ini.parse(is);

    std::cout << "原始 INI 文件" << std::endl;
    ini.generate(std::cout);

    ini.strip_trailing_comments();
    ini.default_section(ini.sections["DEFAULT"]);
    ini.interpolate();

    std::cout << "经过默认部分和插值后的 INI 文件:" << std::endl;
    ini.generate(std::cout);

    std::cout << "访问值" << std::endl;
    std::string host_value;
    if(inipp::get_value(ini.sections["Database"],"Host", host_value))
    {
        std::cout << "Host = " << host_value << std::endl;
    }else
    {
        std::cout << "host = " << "not found" << std::endl;
    };
    

    return 0;
