Re: How to make custom REPL work in ansi-term?

[Jakub T. Jankiewicz]

No it doesn't work in vterm. I got the same error + backspace don't remove
the text. Recently I've found that in fact backspace in Terminal only move the
cursor backwards and to clear the text you need to insert space. It seems
that this is what vterm is doing. I made the same mistake with my ansi code
interpreter.
