How to make UI in Bash?

Question

Python

Good day!
Essence of the question:
There is a certain Python project that has reached such a size that it is no longer convenient to enter data line by line and / or into sysargs, but it has not matured enough to make a full-fledged GUI for it.
A simple UI in bash appears in my head. As a mini utility / program (as an example: the nano text editor)
Due to the low familiarity with bash (and maybe technical illiteracy), I don’t know which way to dig. Please give me direction!
Thank you all in advance!

Answer 1

a quick duck search gives the answer right away - ui on bash !
Zenith !
and as it turned out, he (a) is still, and already, installed (in Linux Mint 18.3)
and everything is not simple, but very simple, here is an example of a window with a form:

zenity --forms --title="Add Friend" \
  --text="Enter information about your friend." \
  --separator="," \
  --add-entry="First Name" \
  --add-entry="Family Name" \
  --add-entry="Email" \
  --add-calendar="Birthday"

the result is returned to stdout in csv format.
see the Zenity UPD Guide : Whiptail for text based user interfaces (TUI) is also already on the system. Bash GUI Whiptail Menu Tutorial Part 1 Also see Glade videos on youtube - BASH Tutorial - Advanced GUI Interface

Answer 3

Bash is absolutely not designed for this. Even if something can be heaped on it, then in Python it is much faster and easier.

I did something on kdialog - I liked it.

Answer 5

I would make a config file - either just a text format like
xxx=123
or in fancy YAML
