一、库介绍
平常的ini配置文件只能读取，但是这个库不光可以读取、写入配置项，还能给配置项写注释。只有一个hpp头文件，不需要编译，支持C 11及之后版本。
MIT license。
二、库使用
- git clone
代码语言：txt复制git clone https://github.com/dujingning/inicpp.git包含 `inicpp.hpp`,声明类 `inicpp::iniReader`,然后就可以随意使用了.
1.读取INI文件示例
代码语言：txt复制#include "inicpp.hpp"
int main()
{
// Load and parse the INI file.
inicpp::iniReader _ini("config.ini");
std::cout << _ini["rtsp"]["port"] << std::endl;
}2.写示例
代码语言：txt复制#include "inicpp.hpp"
int main()
{
// Load and parse the INI file.
inicpp::iniReader _ini("config.ini");
_ini.modify("rtsp","port","554");
std::cout << _ini["rtsp"]["port"] << std::endl;
}3.添加注释
代码语言：txt复制#include "inicpp.hpp"
int main()
{
// Load and parse the INI file.
inicpp::iniReader _ini("config.ini");
_ini.modify("rtsp","port","554","this is the listen port for rtsp server");
std::cout << _ini["rtsp"]["port"] << std::endl;
}* 4.toString()、toInt()、toDouble()
代码语言：txt复制#include "inicpp.hpp"
int main()
{
// Load and parse the INI file.
inicpp::iniReader _ini("config.ini");
_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:tthttp.port = " << http_port_i << std::endl;
}5.完整示例：`example/main.cpp`.
编译demo到example目录下make一下就好了： `example/Makefile` .
没有make命令，只需要执行: `g -I../ -std=c 11 main.cpp -o iniExample`
6.linux下使用demo的完整示例：example/main.cpp
- 编译 `example/main.cpp`
代码语言：txt复制[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- 运行 `iniExample`
代码语言：txt复制[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]$- 生成 `config.ini`
代码语言：txt复制[jn@jn example]$ cat config.ini
