inicpp: 一个头文件（header-file-only）搞定INI文件读写、甚至进行写注释。跨平台，并且用法极其简单。MIT license，从此配置INI文件就像喝水。[ 注：对您有帮助的话，Star或Issues为项目维护提供动力，感谢。] - by offical of JN-inicpp parser project.

Ⅱ、Description

The INI header-only library for Modern C++ supports reading, writing, and even commenting. It is easy to use and simplifies working with INI files.

Ⅲ、Usage

* 0.Simple to use with C++11 or later.

git clone https://github.com/dujingning/inicpp.git

Include inicpp.hpp, declare the inicpp::iniReader class, and you're all set.

* 1.read example

Read: Load file to memory, used directly by the user.

#include "inicpp.hpp"
#include <iostream>

int main()
{
    inicpp::IniManager _ini("config.ini"); // Load and parse the INI file.

    std::cout << _ini["rtsp"]["port"] << std::endl;
}

* 2.write example

Write: Modify directly to the file.

#include "inicpp.hpp"
#include <iostream>

int main()
{
    inicpp::IniManager _ini("config.ini"); // Load and parse the INI file.

    _ini.modify("rtsp","port","554");
    std::cout << _ini["rtsp"]["port"] << std::endl;
}

* 3.or comment

Comment: Write comments for key-value pairs.

#include "inicpp.hpp"
#include <iostream>

int main()
{
    inicpp::iniReader _ini("config.ini"); // Load and parse the INI file.

    _ini.modify("rtsp","port","554","this is the listen port for rtsp server");
    std::cout << _ini["rtsp"]["port"] << std::endl;
}

* 4.toString()、toInt()、toDouble()

Convert: From string to type.

#include "inicpp.hpp"
#include <iostream>

int main()
{
    inicpp::IniManager _ini("config.ini"); // Load and parse the INI file.
    _ini.modify("rtsp","port","554","this is the listen port for rtsp server");
    std::cout << _ini["rtsp"]["port"] << std::endl;

    // Convert to string, default is string
    std::string http_port_s = _ini["http"].toString("port");
    std::cout << "to string:\thttp.port = " << http_port_s << std::endl;

    // Convert to double
    double http_port_d = _ini["http"].toDouble("port");
    std::cout << "to double:\thttp.port = " << http_port_d << std::endl;

    // Convert to int
    int http_port_i = _ini["http"].toInt("port");
    std::cout << "to int:\t\thttp.port = " << http_port_i << std::endl;
}

* 5.isKeyExists()

Check: If the key exists.

#include "inicpp.hpp"
#include <iostream>

int main()
{
    inicpp::IniManager _ini("config.ini");

    if (!_ini["rtsp"].isKeyExist("port"))
    {
        std::cout << "rtsp.port: not exist!" << "\n";
    }
    else
    {
        std::cout << "rtsp.port: not exist!" << "\n";
    }

    return 0;
}

* 6.isSectionExists()、getSectionsList()

May contain unnamed sections: when keys are at the head of the file.

#include "inicpp.hpp"
#include <iostream>

int main()
{
    inicpp::IniManager _ini("config.ini");

    // isSectionExists
    if (!_ini.isSectionExists("math"))
    {
        std::cout << "section of math: not exist" << "\n\n";
    }

    // getSectionsList
    std::list<std::string> sectionList = _ini.getSectionsList();

    for(auto data:sectionList){ // print
        std::cout << data << std::endl;
    }
}

* 7.For a full example, see `example/main.cpp`.

You can compile it using example/Makefile or any other method you prefer.

If make is not available, use the following command: g++ -I../ -std=c++11 main.cpp -o iniExample.

* 8.how to compile example/main.cpp

Compile example/main.cpp

[jn@jn inicpp]$ ls
example  inicpp.hpp  LICENSE  README.md
[jn@jn inicpp]$ cd example/
[jn@jn example]$ make
g++ -I../ -std=c++11 main.cpp -o iniExample
[jn@jn example]$ ls
iniExample  main.cpp  Makefile

Run example app iniExample

[jn@jn example]$ ./iniExample
get rtsp port:555
to string:      rtsp.port = 554
to string:      math.PI   = 3.1415926
to string:      math.PI   = 3.1415926
to double:      math.PI   = 3.1415926
to int:         math.PI   = 3
to wstring:     other.desc= 你好，世界
[jn@jn example]$

then you got config file config.ini
Then you will get the config file config.ini.

[jn@jn example]$ cat config.ini
;no section test:add comment later.
noSection=yes
key0=noSectionAndComment
key1=noSectionAndComment
key2=noSectionAndComment
[head]
;thanks for your using inicpp project.

[rtsp]
;this is the listen ip for rtsp server.
port=554
ip=127.0.0.1


[math]
;This is pi in mathematics.
PI=3.1415926


[other]
;this test for std::wstring. comment it.
desc=你好，世界
