emacs term-mode redraws prompt when backspacing inside executables

5

0

I am reliant on emacs (version 24.4.1 on Debian) term and ansi-term modes. They normally work just like xTerm for me, but when running an interactive program that has a prompt (like the node.js prompt, or the mongoDB prompt), deleting a character makes the entire prompt redraw inline.

For example, when I open the node app and type TEXT followed by a single backspace, I see

jim@achileus:~$ node                                                                  
> TEXT> TEX

and when I type LONGER STRING followed by 13 backspaces I see

jim@achileus:~$ node                                                                  
> LONGER STRING> LONGER STRIN> LONGER STRI> LONGER STR> LONGER ST> LONGER S> LONGER > LONGER> LONGE> LONG> LON> LO> L>

This error does not occur in emacs shell but I don't want to use it.

Any insight as to why this is happening, or any clues on how to fix it?

Thanks!

I don't know the answer, but it sounds like a terminal configuration issue, so I'll suggest checking this in case it's relevant: http://stackoverflow.com/a/22091145/324105

Do you use something like elscreen? – aagaard – 2015-11-28T07:18:08.677

Could it be by any chance related to this: https://emacs.stackexchange.com/questions/9871/extended-cursor-movement-in-terminal-emulator-cha-and-others/10698#10698

I install emacs-snapshot (the newest development release of emacs), and the problem gone. – goFrendiAsgard – 2017-12-22T14:55:27.343
