  • modern-cpp-tutorial

    📚 Modern C++ Tutorial: C++11/14/17/20 On the Fly | https://changkun.de/modern-cpp/

    Project mention: Learning platform for modern C++ with online exercises | reddit.com/r/cpp_questions | 2023-02-11

    I'm going through this Modern C++ Tutorial right now. I didn't need to relearn what inheritance is, just the new language features that are useful.

  • entt

    Gaming meets modern C++ - a fast and reliable entity component system (ECS) and much more

    Project mention: Please roast my ECS implementation | reddit.com/r/gamedev | 2023-02-27

    As a way to force myself to learn more about game engines I've created asimov-ts. While doing it, I tried to refrain from looking at other ECS implementations as much as possible and use only more theoretical sources. As a result, I think it's a bit different from other stuff I've seen like EnTT and bevy_ecs.

    Project mention: Which technology / protocol etc. is the next big thing, coming the next few years in Linux gaming? | reddit.com/r/linux_gaming | 2023-03-20

    - Direct scanout

  • doctest

    The fastest feature-rich C++11/14/17/20/23 single-header testing framework

    Project mention: Question about Doctest.h | reddit.com/r/learnprogramming | 2023-02-05

    Do the README and tutorial not explain it well enough? It's a framework for automated unit testing.

  • Thrust

    The C++ parallel algorithms library.

    Project mention: Parallel Computations in C++: Where Do I Begin? | reddit.com/r/learnprogramming | 2022-09-23

    For a higher level GPU interface, Thrust provides "standard library"-like functions that run in parallel on the GPU (Nvidia only)

  • compile-time-regular-expressions

    Compile Time Regular Expression in C++

    Project mention: Verify all characters are same except a few | reddit.com/r/cpp_questions | 2023-03-09

    Yes to regex, no to std::regex. Better to use CTRE. Something like "^Hello [0-9]+ how are you" should allow checking if there's a match

  • Osiris

    Free open-source game cheat for Counter-Strike: Global Offensive, written in modern C++. GUI powered by Dear ImGui.

    Project mention: skin changer | reddit.com/r/Csgohacks | 2022-10-12

    Project mention: Is it better to learn c or c++ for cuda? | reddit.com/r/CUDA | 2022-04-17

    If you are thinking of using new features through https://github.com/NVIDIA/libcudacxx , you'll have to learn c++

  • concurrencpp

    Modern concurrency for C++. Tasks, executors, timers and C++20 coroutines to rule them all

    Project mention: What happens if you co_await a std::future, and why is it a bad idea? - The Old New Thing | reddit.com/r/cpp | 2023-02-18

    If you look at concurrencpp, you can control exactly where and how coroutines are resumed, using executors.

  • R3nzSkin

    Skin changer for League of Legends (LOL)

    Project mention: 'Fortnite' studio hit with £201million fine and ordered to stop tricking players | reddit.com/r/gaming | 2023-03-17

    Pro tip to league players who wants skins but don't want to spend money: https://github.com/R3nzTheCodeGOD/R3nzSkin

  • filesystem

    An implementation of C++17 std::filesystem for C++11 /C++14/C++17/C++20 on Windows, macOS, Linux and FreeBSD.

    Project mention: Rust's recursive directory iterator 5x faster than CPP | reddit.com/r/rust | 2022-06-16

    On C++ side you may also try ghc::filesystem. It may cache more data fro directory entry.

  • tomlplusplus

    Header-only TOML config file parser and serializer for C++17.

    Project mention: how to handle config files in c++? | reddit.com/r/cpp_questions | 2023-03-06

    Unless you want to make your own config file parser as an exercise (which is a good idea) I'd recommend using toml++.

  • ut

    UT: C++20 μ(micro)/Unit Testing Framework

    Project mention: snatch -- A lightweight C++20 testing framework | reddit.com/r/cpp | 2022-10-18

    It was not easy, I had to modify Boost UT to get it to run my tests. It doesn't support type-parametrized tests when the type parameter is non-copiable, which was the case for me. This is a symptom of a larger issue, which is that it relies on std::apply and std::tuple to generate the type-parametrized tests, which in turns requires instantiating the tuple and the contained objects (even though these instances aren't actually used; eh). That's a no go for me, since I need to carefully monitor when instance are created, and this was throwing off my test code. I had to effectively disable these checks to get it to run without failures. Then there was a similar issue with expect(), which doesn't work if part of the expression is non-copiable. I reported these issues to them.

    If you are fine with open source engine + proprietary data then you can check: https://store.steampowered.com/app/223330/Sea_Dogs_To_Each_His_Own__Pirate_Open_World_RPG/ Engine source code: https://github.com/storm-devs/storm-engine

  • units

    A compile-time enabled Modern C++ library that provides compile-time dimensional analysis and unit/quantity manipulation. (by mpusz)

    Project mention: Why is this piece of code compiling with char as c-tor argument? | reddit.com/r/cpp_questions | 2023-02-07

    Yep. And there are some libraries to provide strong-type int, depending on what you need: type_safe or even units.

  • liblava

    Modern and easy-to-use library for Vulkan

    Project mention: Vulkan all the way: Transitioning to a modern low-level graphics API in academia | reddit.com/r/programming | 2023-03-07

    Sorry for late response! The one I like most is LibLava https://github.com/liblava/liblava I contributed a few features that it was missing for me, and a few other people have done the same, so it's somewhat battle tested. At least two people have used it in academic projects. I like that it gives you full access to the low level parts of Vulkan while still providing high level abstractions over a lot, especially the render loop. The biggest issue imo is lackluster documentation, but it's fairly well organized and readable source code. Build times are also pretty long due to its many dependencies.

  • variant

    C++17 `std::variant` for C++11/14/17

    Project mention: Is there an exception that I could throw if there is a path that should never run. | reddit.com/r/cpp_questions | 2023-01-30

    have a look at https://github.com/mpark/variant
