pytermgui VS no_color

Several libraries, such as urwid or PyTermGUI, allow the development of TUI applications in Python. For enhancing the functionality and aesthetics of TUI apps, they offer some fundamental and more sophisticated utilities. But there is one package that is truly exceptional and might even be so amazing that it sparks a TUI renaissance (I really wanted to put "TUI renaissance" somewhere in this article).

There are plenty of terminal UI libraries that are actually nice to work with. For Python, there's Textual and PyTermGUI. For Rust, there's ratatui and Cursive (or, if you want something a bit lower level, crosster or termion). For Go, there's bubbletea.

Talking about resources, their docs are pretty good and contains some examples too. Documentation: https://ptg.bczsalba.com/pytermgui.html

Have you tried PyTermGUI? It looks promising, but I wonder if there are any pitfalls. I need to build a professional CLI for a robot, and half-baked packages just won't do.

While the community is relatively small right now, my TUI framework PyTermGUI has a lot of the attributes you're looking for! We don't currently have a section dedicated to this yet, but if you come to the discord I'm sure we can help you :)

Check out the changelog here.

I suspect that the reason you didn't find much is that usually people need a whole textual user interface (or TUI). And there's quite a few libraries for those, like pytermgui or textual, and some more low-level tools in that area like prompt-toolkit

This sounds like a really good pattern, and something that deserves to become a modern standard (like https://no-color.org/).

I feel like this should be made opt in somehow. If you are a noninteractive process and stdin is a tty then you probably shouldn't be swallowing input. I frequently blind-type the next command while a long running command is active, because well behaved noninteractive programs don't swallow input from stdin.

Does this support the environment variable for NO_COLOR too? https://no-color.org/

Some of us prefer tools which work best without them.

Allow me to repeat my plea for CLI developers to take a little time to read https://no-color.org and ensure their programs honor things like NO_COLOR, npm config set color false, TERM=dumb, INSIDE_EMACS etc.

Change: [#1908] Detects if terminal is VT100 capable and uses colors for the output, can be disabled using NO_COLOR.

Why not let termenv do the hard part of making this portable across terminals? It also supports lesser-known conventions like NO_COLOR.
