When using erlang.get_line() and you press backspace it deletes the last word not the last character. Here is my code:

import gleam/io
import gleam/string
import gleam/erlang

pub fn main() {
  case erlang.get_line("What is you name? ") {
    Ok(name) -> io.println("Hello, " <> string.trim(name) <> "!")
    Error(_) -> io.println("Something went wrong")
  }
}

This library does not implement that function, it is part of Erlang, so we may not be able to help. The Erlang forums may be the place to ask. https://erlangforums.com/

Does it happen if you call it from the Erlang shell or an Erlang program?

[joshuafocht]

Sorry that I didn't see your comment till now. It does not happen when calling from erlang or the erlang shell.

Another thing I forgot to mention, it only happens on windows, so it might have something to do with CRLF.

Does it only happen when using get_line? Does it happen when using gleam export erlang-shipment?

[joshuafocht]

Does it only happen when using get_line?

I have only tried get_line. Is there an alternative?

Does it happen when using gleam export erlang-shipment?

I just tried that, and it still happens.

Could you try in Erlang after running these please

    io:setopts(standard_io, [binary, {encoding, utf8}]),
    io:setopts(standard_error, [{encoding, utf8}]).

[joshuafocht]

I have just tried that, and it still works in erlang.

I'm confused as I can't think of anything that differs between the working erl scenario and the not working shipment scenario.

[joshuafocht]

I think it has something to do with windows because it only happens there.
