same

A lightweight, header-only compile-time type comparison utility for C++11 and later.

same compares two template types and exposes a compile-time boolean result.

Requirements

• C++11 or later
• CMake 3.16 or later for CMake integration

Usage

#include "same.h"

static_assert(same<int, int>::value, "same type");
static_assert(!same<int, double>::value, "different types");

For more examples and API documentation, see Usage Documentation.

Manual Integration

Download same.h from the repository and add it to your project's include directory.

Include the header using #include "same.h". No separate compilation is required.

CMake Integration

same can be integrated directly from GitHub using CMake's FetchContent module.

Add the following to your project's CMakeLists.txt:

include(FetchContent)

FetchContent_Declare(
    same
    GIT_REPOSITORY https://github.com/DanielArndt0/same.git
    GIT_TAG v1.0.0
)

FetchContent_MakeAvailable(same)

target_link_libraries(my_target PRIVATE same::same)

Replace my_target with your application's CMake target.

If you already have the same source directory inside your CMake project, you can add it instead:

add_subdirectory(path/to/same)
target_link_libraries(my_target PRIVATE same::same)

same is header-only and does not require a separately compiled binary.

Compatibility

same requires C++11 or later. It has no external dependencies.

Disclaimer

same is developed for educational purposes and experimentation with templates. It is not intended to replace std::is_same.
