Introduction

This is a header only implementation of the ini file parser with modern C++.

Build test

cmake . -B build -DCMAKE_BUILD_TYPE=Release 
cmake --build build

cd build && ctest -C Release --output-on-failure

Use it in CMake project

Add the following code in your CMakeLists.txt file.

Example cpp code

  #include <settings.h>
  constexpr const char path[] = "/etc/cfg/my_settings.ini";
  using MySettings = Settings<path>;

  auto& settings = MySettings::GetInstance();
  // string
  settings.SetValue<std::string>("string.key1", "value1");

  // float
  settings.SetValue<float>("float.key1", 1.1);

  // get operation with no default value.
  auto value = settings.GetValue<std::string>("string.key1");

  // get operation with default value.
  value = settings.GetValue<std::string>("string.key1", "default_value");

  // get operation with format args. `GetValue2` version.
  value = settings.GetValue2<std::string>("default_value", "%s%d", "string.key",1);
