Turbo Vision VS FTXUI

For those curious, here is a modern port of the C++ Turbo Vision that also supports Unicode:

Not exactly what you're looking for, but there's Shell in a Box (see https://github.com/shellinabox/shellinabox), that can create a terminal on a web page, and expose an actual terminal application running on a server.

One thing that is certainly doable is also to use a standard TUI framework in another language (there are many of them, e.g. https://github.com/magiblot/tvision for C++, https://github.com/charmbracelet/bubbletea for Go, etc.), compile it to WASM, and find how to bridge the WASM output to the browser (I've seen this: https://github.com/cryptool-org/wasm-webterm, but never tried it).

With FPC, you can use Free Vision, which is a supposed to be like a remake of the old Borland Turbo Vision. Alternatively for C++.

Talking about a window display from byte array sounds like windowing for a purely text based (console based) user interface, like the 1990's Borland's old Turbo Vision. There are modern ports of Turbo Vision, e.g. superquick googling found one at GitHub.

there is also a port of the "original":

A modern port of Turbo Vision 2.0, the classical framework for text-based user interfaces. Now cross-platform and with Unicode support.

But then i'm an engineer and doing things in organize manner is what i am supposed to do. And one day i came to this repo FXTUI a fantastic C++ library for creating terminal user interfaces, so i started building tuisic.

libaloo is a C library which uses GTK4 behind the scenes to create an GTK application It’s mainly written in C. It also has a CLI and CLI with TUI written in C++ with FtxUI but to set it up, Python is used.

FWIW, I evaluated a dozen compiled TUI libraries and found FTXUI to be the easiest to use and most reliable:

It's a nice tool to build interactive dashboards with both keyboard and mouse support.

Background: I want to make a NES Tetris) clone for the terminal, with full resolution, this is achievable through using this ▀ character, and defining back and foreground color. This would result in a 1x2 pixel and by making the game width 256x120 characters this would provide full resolution. I made some tests, creating my own encoding for the different sprites and optimizing everything, which resulted in very quick printing times, even with a normal terminal. Nearly fast enough for the full 60Hz that the NES has, when printing the whole screen. The fact that i don't need to reprint the background (except maybe a tetris), makes 60Hz a kinda realistic goal. My main concern is, that there could occur kind of a screen tearing effect, which i really want to avoid. AFAIK, ncurses has a way to print the whole "window" with a function call to avoid this issue, however I had a lot of issues when trying to use ncurses to print the entire background and figured, that there are better alternatives. I also tried FTXUI and whilst the experience of giving each "pixel" a fore- and background color was much better, i didn't quite find a way to refresh the screen like ncurses. (i think there is some kind of way with the ScreenInteractive class, but i didn't get that to work, and it seemed like there was not a way to color each pixel. with InteractiveScreen you can make your own components with the whole "text()" thing, but this isn't really what i need)

Try this library for console https://github.com/ArthurSonzogni/FTXUI

Depends on which level of "UI" you want. Personally I like https://github.com/ArthurSonzogni/FTXUI , but if you want to do those old TUI things then probably the (n/pd)curses libraries.
