Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Making a "constant mapping"
I found this extension that implements "frozen" versions of some C++ containers, but I was wondering if there is a good solution available in the standard library.
-
Static map - is it possible?
A library exists that can produce constexpr hash table based containers.
-
What C++ library do you wish existed but hasn’t been created yet?
I use the Frozen library for that. Since the conversions should be known at compile time you can make constexpr hash tables for lookups.
-
Command-line util for class implementation (My first try at a professional c++ application)
The constexpr dependency of note here is frozen.

Ambition is cute.
In C++, a drop-in replacement for your DSA can provide significant improvements over the standard library. Particularly the standard unordered_map class can be improved by 50% to 100% (e.g. https://github.com/greg7mdp/parallel-hashmap, or for static maps https://github.com/serge-sans-paille/frozen). Of course, recognize that creating a DS/A from scratch is an entire project, and you shouldn't roll your own for an independent codebase.

May 2021 monthly "What are you working on?" thread
In the language, I added anonymous array literals. I did some cleanup in the compiler and updated to LLVM 12 from 10 (which was pretty trivial, surprisingly). I also added frozen, a C++ perfect-hashing library, as a dependency to speed up the lookup of keywords in my lexer. The library exploits C++’s constexpr features to generate a perfect hash at compile-time without any separate build step, which is great, and it also provides a drop-in replacement for std::unordered_map that uses the hash.

What (relatively) easily to implement features would you like to see in c++23.
I’ve no idea how hard it is to implement, but return type polymorphism would be nice. Especially returning different things based on the constexpress of the result. And then add Frozen eqivalents of associative containers to the STL, so that, for example constexpr auto set = std::make_set(...) would be frozen::set, and auto set = std::make_set(...) would be std::set.
-
Compile-time INI config parsing and accessing with C++20
In which case, I believe the answer your question would be yes: the frozen map.

Black Triangles
It's fun to see the evolution in e.g. these examples of image loading for Dear Imgui:
https://github.com/ocornut/imgui/wiki/Image-Loading-and-Disp...
DirectX9 will even load the image for you, DirectX11 okay we get a few more structures to fill out, DirectX12 is where it goes off the rails and we are filling out a bunch of UNKNOWN DONT_CARE JUST_DO_IT. Then of course Vulkan is the one that gets the big fat "this probably won't actually work for you" warning.
I understand whats happening, but you know sometimes I just want to display a fucking image.

Dear ImGui: Bloat-free Graphical User interface with minimal dependencies
ImGui is engine/GPU agnostic
Themeing isn't a just a retained mode thing, you can do wonders with immediate UIs, even thought (dear)ImGui doesn't provide much, you can still do wonders: https://github.com/ocornut/imgui/issues/707#issuecomment-362...

Where do I start to learn C++ for a game development
Bonus: If you want to make desktop app with UI, then this is another great C++ library and it's also simple to learn as well. https://github.com/ocornut/imgui.

GUI library for fast prototyping
AFAIK the Rust equivalent to C++'s Dear ImGui is egui.

Stretching myself thin with Dear ImGui projects
They use a Dear ImGui, a C++ GUI library.

PCSX2 Disables Wayland Support
Aside from bugs and driver issues, Wayland has some unfortunate design limitations. For example, Dear ImGui multi-viewports don't work because "Wayland doesn't let application read or write windows positions."
https://github.com/ocornut/imgui/wiki/Multi-Viewports
This is a feature available on Windows, macOS, and of course X11. Making choices like this means desktop Linux becomes even more of a weird island that nobody wants to support.
