Unexpected command line position after closing vim

  • 1.  Unexpected command line position after closing vim

    Posted 06-03-2020 16:22

    I’m running Ubuntu 20.04 on Windows 10 under the Windows Linux Subsystem. When I ssh into USS on the mainframe, vim works fine, except that upon exit the command line and cursor go to the top of the display, overwriting what was there before. The rest of the data on the screen is left behind.

    What can I do to make the command line redisplay directly under the vim invocation, as expected? Thanks!

    Hello tony.vitonis,
    We can’t reproduce this issue. Can you give us some details

    1. fully described steps
    2. “env | sort” output from both systems
    3. screenshots will be helpful
    4. .vimrc content
    5. which terminal are you using

    Thanks,
    Alex

    Reproduce

    1. ssh to z/OS.
    2. Enter a vim command.
    3. Quit out of vim.
    4. Note that the command line is redrawn at the top, and that the rest of the screen is still there.

    Before entering vim

    After exiting vim

    For some reason, I can’t put a second screenshot here because I’m a “new user”. I’ll add it in a following post.

    I’m using the terminal that’s automatically invoked by the Windows 10 Ubuntu app. As for my .vimrc content, it’s largish and works in every other environment I’ve tried it. Is there something specific that you’re looking for in there? Values of settings?

    Aha! My vimrc file did have some “special” screen-related code in it:

    if &term =~ "xterm"
       let &t_Co = 256
       let &t_ti = "\<Esc>7\<Esc>[r\<Esc>[?47h"
       let &t_te = "\<Esc>[?47l\<Esc>8"
       if has("terminfo")
          let &t_Sf = "\<Esc>[3%p1%dm"
          let &t_Sb = "\<Esc>[4%p1%dm"
       else
          let &t_Sf = "\<Esc>[3%dm"
          let &t_Sb = "\<Esc>[4%dm"
       endif
    endif
    

    Apparently at some time in the past I had tried (and failed) to address the problem. Anyway, the symptom now is that when I exit vim, the final contents of the vim session remain visible and the previous terminal session lines are scrolled off:

    My ultimate goal is to have vim on z/OS behave as it does in other places, meaning that I want it to restore the screen as I saw it when I invoked vim and put a new command line at the bottom. How can I accomplish that?

    I knew that all of this sounded familiar! I found an old forum post of mine and followed the instructions there. Everything’s good now. Thanks.
