An extended C++ standard library.
This project is dedicated to adding useful features for C++ developers that utilize cutting edge C++ versions and techniques. Many useful features that the standard cannot have due to its constraints will be here. Upgrades to existing standard libraries will also be here, as a way to test out what a std2 might be like.
Any of the public or private APIs here can change at a moments notice. All libraries, even those deemed "Done" are all experimental and serve the purpose of furthering whatever I choose them to be.
| Library | Description | Code Status | Test Status | Doc Status |
|---|---|---|---|---|
| platform | Probe the type of architecture, operating system, compiler, and C++ version you are using at compile time | ✅ | ❌ | |
| type_traits | Additional type traits | ✅ | ❌ | |
| strings | More string abstractions and algorithms | ❌ | ||
| io | A reimagining of C++ streams and other io functionality | ✅ | ❌ | |
| fmt | A reimagining of fmt utilizing the io library | ✅ | ❌ | |
| test | A test case framework | ✅ | ❌ | |
| benchmarking | A benchmarking framework | ✅ | ❌ | |
| match | A pattern matching framework | ❌ | ||
| scan | The flip side to fmt. A modern approach to scanf | ❌ |
✅: "Done"
❌: Haven't started
This project uses CMake with modern C++23 features. No outside dependencies other than a C++23 compiler and an up to date CMake.
I haven't gotten installing down yet, as C++ modules with CMake are experimental and still have its issues. I believe once I find a separate project that will utilize these set of libraries, I'll figure that out.
My CMake tests are automatically generated and ran through a single test runner executable.
The best way to run all the tests at once is to go into the build/tests folder and run .. -C Debug --output-on-failure.
There is a benchmarks folder that holds various benchmarks to run. This is intended to check my implementations against the standard, or to prototype or demonstrate certain features. There is a cmake target for each file to create an executable that will print results.
