subb VS textual

I wrote this to simplify just that for my own tools; the subprocess module that comes with the batteries has a very general interface, i think that it is a bit complex for a quick script.

Python doesn't have the problem of shell scripting language, it doesn't get impractical, as the program is getting more complex. In bash you have arrays, and even maps, but these aren't pretty. Also the shell scripting language is being evaluated by an parse tree/AST interpreter, that's significantly slower than even python, in it's byte code interpreted form.

My objective was to get an abstraction, for a one line process run and extraction of the result, similar to what we had in Perl5 with the system library function. https://perldoc.perl.org/functions/system

Also the shell is impractical, when it comes to slightly more complex programs. There is a limit on what you can do with pipes. Maybe that's the reason why perl is that flexible, as they tried to bridge both realms: Perl had to be useful as a replacement for the quick shell like script, and to be useful as a general purpose programming language.

i have a subprocess wrapper, might also be of help: https://github.com/MoserMichael/subb

The Textual project has a lot of screenshots in its documentation. These screenshots are built with the docs, so they are always up to date.

Textual[0] does this for CLI apps. That’s not for full GUI apps, but it’s very DOM-like, uses CSS selectors, etc. and a cool option when it meets your needs.

For future projects that need a TUI beyond normal printing to a terminal, I'd recommend taking a look at Textual.

`less -R` is not the default.

FWIW, textual (and urwid) does ANSII escape codes well: https://github.com/Textualize/textual

  touch file$'\n'name

After installing logmerger, you can run a self-contained demo by running logmerger --demo, to view two log files before and after they are merged, and to play with the user-interface features provided by textual.

I think it just survived naturally, filling in the cracks left by Java / C++.

And not the era of Textual (https://textual.textualize.io/) is here, python may get the spotlight even more.
