Python streamlit does not work

[ChrisSpoti]

Hi All,

Is it possible to support python’s streamlit ? When I try to install and run it I always get the following errors.

thanks a lot, Chris

$ streamlit hello

I'm a little sceptical about how you could use a graphics user interface library in pure-text application.

But I think the main blocking point is going to be the JavaScript flavor: streamlit seems to depend a lot on React, which is not available on iOS.

First of all, many thanks for your awesome application ! I read issue #494 about the tkinter, that there's currently no way to connect to the iOS GUI from inside the terminal. As I understand it, KivyMD doesn't work either. So, I thought about Python with any Web UI. The goal is to have python with any simple GUI. Do you plan to have any GUI for A-Shell in the future ?

[holzschu]

The plan is for a-Shell to remain a text-based terminal (mainly because adding a GUI is a lot of work). However:

• We do support the textual Python package: https://pypi.org/project/textual/ so you can actually write a GUI. It will run in the terminal, using text strings, but it can have buttons and a lot of interfacing.
• Because the terminal window is technically a web window, you can run JavaScript programs, including programs that display JS alerts to ask questions or request confirmation from the user. Interfacing Python and JS is not easy, but feasible.
• There is another app, Carnets-Jupyter, that runs the same Python, but with the more common Jupyter notebook interface.

I'm not strongly against adding support for another GUI, it's more that there's already a lot of things to do, and these things look impressive.

I could be completely mistaken but I didn't think that Streamlit would require you to have a GUI in a-shell as it creates webapps. However, there may be required libraries that are not present and cannot be user installed.
