Build Status

This is a header only C++ version of inih.

inih (INI Not Invented Here) is a simple .INI file parser written in C. It's only a couple of pages of code, and it was designed to be small and simple, so it's good for embedded systems. It's also more or less compatible with Python's ConfigParser style of .INI files, including RFC 822-style multi-line syntax and

name: value


All you need to do is to include

. Consider the following example (
#include "INIReader.h"

int main() {

INIReader reader("test.ini");

if (reader.ParseError() != 0) {
    std::cout << "Can't load 'test.ini'\n";
    return 1;
std::cout << "Config loaded from 'test.ini': version="
          << reader.GetInteger("protocol", "version", -1) << ", name="
          << reader.Get("user", "name", "UNKNOWN") << ", email="
          << reader.Get("user", "email", "UNKNOWN") << ", pi="
          << reader.GetReal("user", "pi", -1) << ", active="
          << reader.GetBoolean("user", "active", true) << "\n";
return 0;


To compile and run:

g++ INIReaderTest.cpp -o INIReaderTest.out
# Config loaded from 'test.ini': version=6, name=Bob Smith, [email protected], pi=3.14159, active=1
