stdcpp: Standard Library Implementations

Overview:

The stdcpp project provides custom implementations of various standard C++ library functions. This is particularly useful in scenarios where the standard library is not fully supported by the compiler or the target environment. The project aims to offer a reliable alternative for developers facing such constraints.

Minimum Requirements:

C++14

Usage Instructions:

To utilize the stdcpp library, simply include the desired header file in your C++ project. The library is structured to be straightforward and easy to integrate.

Features and reason:

Header	class or function	Description	Reason
shared_mutex	shared_mutex	Provides a shared mutex implementation for C++14 and Windows XP.	AcquireSRWLockExclusive is supported since Windows 7.
utility	to_underlying	Provides a to_underlying implementation for C++14.	std::underlying_type is supported since C++23.
string	u8string	Provides a u8string implementation for C++14.	std::u8string is supported since C++20.
ranges	basic ranges	Provides basic ranges implementation for C++14.	std::ranges is supported since C++20 and C++23.
string_view	basic_string_view	Provides a basic_string_view implementation for C++14.	The time_zone needs string_view
iterator	iterator_traits	Provides a iterator_traits implementation for C++14.	std::iterator_traitsstd::common_iterator or some related iterator traits for ranges are defined since C++20
chrono	clock series, tz, calendar	Provides a clock series, tz, calendar implementation for C++14.	std::chrono::calendar is supported since C++20.

Building the Project:

stdcpp is primarily a header-only library, streamlining its integration into other projects. However, for those interested in compiling the library, follow these steps using CMake:

mkdir build
cd build
cmake ..
make

Testing:

The project includes a comprehensive suite of tests to ensure reliability and correctness. These tests are automatically configured through CMake. Upon building the project, test binaries are created in the build directory. These are named following the pattern t_<header_name> and can be executed to validate the functionality of each header file.

Contributing:

Contributions to stdcpp are welcomed and appreciated. This can involve adding new header files or enhancing existing ones. When contributing new headers, ensure that they do not duplicate functionality already present in the standard C++ library. Your efforts help in making stdcpp a more robust and extensive library.
