Spinners overwrite several lines of existing terminal output #35

Closed toadslop closed 4 months ago

toadslop commented 4 months ago

Hey, great library! The spinners are beautiful and its pretty easy to use. When trying to integrate it into a CLI at work though, we found a bug that unfortunately makes it unusable in a production application. The problem is that the spinners overwrite some lines of existing terminal output, which might be important to the user. It would be great if you could fix this because we would love to use this library otherwise.

added .clear method

Sets the number of rows to clear in the terminal before starting the animation. If no value is provided, the terminal will clear all rows by default, effectively clearing the screen without deleting old content, which might leave empty rows.

Example

use zenity::spinner::MultiSpinner;
use zenity::spinner::Frames;

let spinner = MultiSpinner::new();

// Clear with the default number of rows (entire terminal)
spinner.add(Frames::default());

// Clear with a specified number of rows (12)
spinner.clear(Some(12));

// Dont Clean anything
spinner.clear(None);

spinner.run_all()

Parameters

rows: An optional u16 specifying the number of rows to clear. If None, no rows will be cleared.
