bug#70562: Trouble using Vim under Emacs's ansi-term

[C.J.S. Hayward]

I have Emacs 21 as installed from Linux Mint Victoria.

I am a long-time Vim user interested in a proportional font terminal, such as is mostly provided by Emacs Evil mode or local or (ssh) remote Vim, but I have experienced consistent issues using vim under Emacs's ansi-term.

I haven't been able to pin down that if you edit a particular document and attempt a particular set of keystrokes, issues arise. However, I have had issues with Emacs thinking it is one line higher or lower than it really is, so that commenting out a line of JavaScript comments out a different line from what the user intended (and what it appears), and random freezing.

I believe that if you have a volunteer who is comfortable using Vim, and ask said user to use Vim under Emacs's ansi-term for half an hour (I have not been able to discern different behavior between local Vim processes and those ssh'ed into a Linux server), the odd behaviors I have experienced will be reproduced. Based on my own experience, I believe some inappropriate behavior will probably be noticeable in 2-5 minutes, but I mention half an hour as adding slop.


Thanks,

Do I understand correctly, that you are using Emacs 21, released
somewhere between 2001 and 2005?

I am comfortable enough with vi(m) and I tried out some non-trivial text
manipulation but couldn't notice anything wrong.  If you are actually
using Emacs 21, then it might be that in the ~20 years since its release
the bugs causing the issues you have been having have been resolved?  I
would also recommend trying out the ELPA package "eat" as an alternative
terminal emulator, but that would also require a newer version of Emacs.
