ARLib

A simple WIP C++20 implementation of standard containers and library features that aims to be compatible with MSVC/GCC/Clang on 64 bit Windows and Linux systems.

Note: the developer of this library is not responsible for any error caused by it. Everything is based on necessity as it is a personal project done mostly for fun. PR and issues are welcome but not guaranteed to be fixed/merged. Do so at your own discretion.

For now it relies on:

• <compare> for std::strong_ordering
• <type_traits> for std::is_foo_constructible<T, Args...>, std::is_foo_assignable<T, Args...>, std::is_union<T>, std::is_enum<T>
• <cstdio> for file and console I/O, and for some number -> string conversions.
• <immintrin.h>, <intrin.h> for vector instruction intrinsics.
• <typeinfo> for typeid(Cls).name()
• <new> global operator new/new[]/delete/delete[] because I'm not implementing my own malloc and for placement new.
• <initializer_list> for std::initializer_list<T>
• <pthread.h> on Linux, this dependency can be disabled with -DDISABLE_THREADING passed upon running CMake.

This library has been compiled and tested with:

• MSVC 19.36.32532
• GCC 13
• Clang 16
• Mingw x64 with GCC 13

To build on Windows the minimum version of Visual Studio required to build is VS 2022 v17.6.

How to build

Simply run cmake with the preferred settings of your choice. For a standard release linux build for example:

git clone https://github.com/Atari2/ARLib
cd ARLib
mkdir build
cd build
cmake -DCMAKE_C_COMPILER=clang-16 -DCMAKE_CXX_COMPILER=clang++-16 -DCMAKE_BUILD_TYPE=Release -G "Ninja" ..
ninja

If you want to use make just remove the -G "Ninja" and call make after instead of ninja.

For a standard release windows build:

git clone https://github.com/Atari2/ARLib
cd ARLib
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build . --config Release

To add this library to your cmake project, simply use the following in your CMakeLists.txt

include(FetchContent)

FetchContent_Declare(
	ARLib
	GIT_REPOSITORY "https://github.com/Atari2/ARLib"
	GIT_TAG master
)

FetchContent_MakeAvailable(ARLib)
target_include_directories(YOUR_PROJECT PRIVATE ${ARLib_SOURCE_DIR})
target_link_libraries(YOUR_PROJECT PRIVATE ARLib)

This requires CMake at least version 3.15
