  • Weirdness with backspace on python and bash

    From Daniel@3:633/10 to All on Wed Oct 15 06:30:01 2025
    I have a few tools on my bbs written in bash or python which
    prompts the user to type into a field. The normal characters output
    properly, but if I use backspace, I end up getting some sort of ascii
    output of the key values. Or something. Below is the screen output for each
    key I press. I don't care if arrows work or not. But I'd like backspace
    to work as designed instead of spamming my screen.

    Key Output
    Backspace ^H
    Right arrow ^[[C
    Left Arrow ^[[D

    So I can't even erase what I have in the field and need to start
    over every time.

    I've tried to explicitly define those keys as what they are in
    code but, my skills need improvement because none of it worked. I tried
    using AI in the past but it gave me some bugged crap that took more time
    to debug than it would've taken if I just coded it on my own. I'm asking
    for insight from yalls fine people. What can I do to fix this? I'm
    hoping the solution is simple.

    Using syncterm 1.8b updated Oct 6, 2025.

    Thanks,

    Daniel

    When calling the script from the menu editor, do something like;

    Command | (DD) Exec external program
    Data | stty erase '^H' && /mystic/themes/default/scripts/scriptname.sh

    That's how I got around the backspace as delete issue, this should help you find the answer to the other keys too.


    Cheers!

    Thank you so much broham. It appears, though, I can only implement
    one. When I do:

    stty erase '^[[C' && stty erase '^DD' && stty erase '^H' ...
    the arrow keys still output the junk.

    You can't map the arrow keys to erase afaik, you'd have to do something else or leave them as just arrow keys, which is what I'd probably do if it were me.
