multiline input: unable to delete previous lines

[mcpcpc]

This behavior was first reported as part of mcpcpc/kirc#39 and appears to impact multiple terminal emulators (e.g. foot and st) while behaving fine in others (e.g. xterm)

To reproduce, one simply needs to read input from stdin (e.g. fgets) and type more characters than the width of the terminal window. the text that is longer than window width is then printed as a new line, making the previous line uneditable.

A simple verifiable example (written in C) includes the following:

#include <stdio.h>
#include <stdlib.h>

int
main() {
    char a[1000];
    fgets(a, 1000, stdin);
    printf("string: %s\n", a);
    return 0;
}

Yeah, I can confirm that this is happening. In this case It is probably worth testing with gnome-terminal and/or reporting the issue to with libvte as that is basically all I'm using here.

This could also be somewhat related to the issue: https://gitlab.gnome.org/GNOME/vte/-/issues/62

ahh yes! somehow missed this one =S. Item 2 is identical to the issue. also, i can confirm that the behavior is “fine” with using a terminal multiplexer, such as screen.

seems that the best solution, until corrected upstream is to use urxvt, screen or tmux.

I am always within tmux and/or neovims terminal thus I haven't really noticed this.

Here's another relevant conversation I am having with the developer of the foot terminal emulator: link.
