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.

Notcurses. Install it and run notcurses-demo to be suitably impressed.

Ratatui: Build rich terminal user interfaces
Same for me, I would be much more motivated if there was something like textual for Rust. Given the capability of terminal emulators now I think Rust is lacking behind in the TUI field. Just checkout what can be done with something like notcurses

Io Uring
The broader world probably knows him best for the terminal handling library Notcurses[1] and a lot of telling terminal emulator authors to get their shit together.
I’ve had his grad-school project libtorque[2] (HotPar ’10), an event-handling and scheduling library, on my to-read list for years, but I can’t seem to figure out how it accomplishes the interesting things it does.

Are We Sixel Yet
In XTerm, this (rightly) makes no difference. In Foot and Contour however, you still end up a line resp. a screen below where you started, if now with the correct horizontal position.
So it seems to me like what you want should work by default, except it doesn’t.
It should be possible to instead just treat the whole thing as a graphical overlay (by computing or directly asking for the character cell size, as Kirill Panov rightly admonishes me is possible with XTWINOPS) without touching the cursor; that’s what the “sixel scrolling” setting (DECSDM) is supposed to do. Then you can just manually move the cursor forward however many positions after you’re done drawing.
Except apparently the DEC manual (the VT330/340 one above) and DEC hardware contradict each other as to which setting of DECSDM (set or reset) corresponds to which scrolling state (enabled or disabled), and XTerm has implemented it according to the manual not the VT3xx[1,2,3]—then most other emulators followed suit[4]—then XTerm switched to following the hardware[5,6] (unless you and that’s what I’m seeing on my machine right now. So now you need to check if you’re on XTerm ≥ 369 or not[7]. If I’m reading the Notcurses code right, other terminals have followed suit[8].
Again, ouch.
P.S. It seems DEC had an internal doc for how their terminals should operate (DEC STD 070) [9]. It does not document DECSDM at all.

Sharing Saturday #453
Once I have finished documenting all of the existing API functions and structs, I will begin work on terminal rendering. While the API surface area will only be slightly increased (a single function to set some flags) the actual work will mean building a parallel renderer for both Linux and Windows. I will be looking into notcurses to see if it can make my life easier in this regard.

What are some C++ projects with high quality code that I can read through?
I find openMVG very decent, FTXUI might be a good one and nlohmann's json library is also pretty nice. I don't really know of any project that strictly adheres to the core guidelines, except maybe for some of Jason Turner's (sample) projects.

I have made a physics simulator that replicates projectile motion with quadratic drag! Please feel free to download and compile it. Let me know of any bugs!
Okay stupid suggestion I know but I've recently been learning the FTX UI library which basically adds a little bit of UI programming to the terminal and it has canvas that lets you plot pixel by pixel.

Cross Platform Terminal UI Toolkit for .NET
On the C++ front, I've been using this and love it - https://github.com/ArthurSonzogni/FTXUI - it also has wasm target, so may target the web.
I'm regular Far Commander on Windows, and Midnight Commander, also known as mc on Linux/OSX. In fact my "Command-Prompt" on Windows is always FAR (this comes with certain limitations, but I'm so used to it, I can't do my normal work without it). I could never get into the Explorer, and only use it in rare cases.

What are some cool modern libraries you enjoy using?
Just discovered FTXUI - a library for creating functional user interfaces on terminal. It supports clickable stuff and even plots. https://github.com/ArthurSonzogni/FTXUI Jason Turner also has a starting repository with all the boilerplate ready: https://github.com/cpp-best-practices/ftxui_template

how does neovim/vim's ui work in a console?
As already said, you can print ANSI escape codes to change colors/effects. But there are also many high-level libraries to create TUIs, such as FTXUI and notcurses

RoguelikeDev Does The Complete Roguelike Tutorial - Week 8
FTXUI is used to display terminal graphics, please check out this awesome library, it has a lot to offer, I even was able to handle mouse events with it! And the best part is that the code is very easy to compile for the web with emsdk so right from the beginning it was available online without much hassle.
