The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

CXXIter: A chainable c++20 LINQ-like iterator library
Have you seen libflow? It's also built on the same model (Rust-style iterators), curious how they compare.

Modern C++ in Advent of Code
Just to get on the bandwagon: here are my C++20 Advent of Code solutions, mostly using my work-in-progress Flow library

T* makes for a poor optional<T&>
Perhaps relevant since Barry mentioned my Flow library as an example: the following (written a couple of years ago for another Reddit thread) is what would appear in Flow's documentation as a justification for using optional references -- if Flow actually had any documentation, that is...

Is it well defined if you pipe a stateful transform into views::drop?
If you want to use the Rust iterator model in C++, then you can do so.

What are coroutines even for?
I have a work-in-progress-for-a-long-time-now functional-style programming library called libflow, which uses Swift/Rust style iterators. It has optional support for coroutines ("flowroutines", heh) which can make writing "one-shot" iterators very simple indeed.

[C++20] ClearIO library (unfinished)
Yeah, but parsing format strings in runtime induces an overhead, and doing it in compile time is not trivial, and I’m not sure ClearIO is worth the trouble, since it turns out scnlib exists.

My AoC2021 solutions in C++
The code is rather nice (in my biased opinion) and makes heavy use of a couple of libraries like scnlib and [Eigen](eigen.tuxfamily.org/). Some things could probably be more optimized but I mainly focused on conciseness. I hope this is useful and I can explain my thought process further if you have any questions.

what annoys you most while using c++?
I've found https://github.com/eliaskosunen/scnlib but haven't tested it. Maybe that suits your needs for 2.

The Year is 2022 and the Standard is C++20; what is your preferred way to do Text I/O?
I had a user enum like enum class Color {Red, Green, Blue}; that I wanted to add serialization support for. Following the docs (https://scnlib.readthedocs.io/), after some tweaks I arrived at the following:

scnlib (scanf for modern C++) - version 1.0 released
Thanks for the comment, I made an issue tracking this: https://github.com/eliaskosunen/scnlib/issues/51
