Vim – Disable Visual Mode in /etc/vim/vimrc on Debian

debianvivimvimrc

I found plenty of questions regarding disabling visual mode in vim but none that tackles my particular problem:

I added set mouse-=a to my /etc/vim/vimrc file to disable visual mode for good. Thing is: That seems to do nothing. However when I put the exact same directive into my user's .vimrc file it works.

Is this expected behaviour? Did I miss something? Has anyone a solution which doesn't involve managing a .vimrc file for each and every user?

Thanks in advance!

I am on Debian 10, fully updated by the way.

Debian's /etc/vim/vimrc contains this comment:

" Vim will load $VIMRUNTIME/defaults.vim if the user does not have a vimrc.
" This happens after /etc/vim/vimrc(.local) are loaded, so it will override
" any settings in these files.
" If you don't want that to happen, uncomment the below line to prevent
" defaults.vim from being loaded.
" let g:skip_defaults_vim = 1

As :verbose set mouse? says, that was set by /usr/share/vim/vim81/defaults.vim mentioned above ($VIMRUNTIME on Debian would be /usr/share/vim/vim<version>).

So, you can either create a ~/.vimrc (or ~/.vim/vimrc) for your user (even an empty one will do), or uncomment let g:skip_defaults_vim = 1 in /etc/vim/vimrc.

Why does Vim only activate the highlight configuration after I source the .vimrc manually

The issue is caused by the sensible plugin:line 93. :help t_Co

" Allow color schemes to do bright colors without forcing bold.
if &t_Co == 8 && $TERM !~# '^linux'
  set t_Co=16  " << --- Causes hickup
endif

If you run vim in verbose log mode (vim -V15load_log.vim) – and search for t_Co= and RedundantSpaces you'll see that sensible is actually parsed after your appearance.vim file.

Quick fix would be to either comment out that section of the code and add it to your .vimrc, but as you link to git repositories that is perhaps not what you want.

A different approach would be to move it out of the bundledirectory and add it as a separate source line in your vimrc, before your glob loop.

I.e.:

  source ~/.vim/hacks/vim-sensible/plugin/sensible.vim

  for f in split(glob ...

Another way would be to load custom highlight on BufLoad.

Vim – Is there a way to get immediate visual feedback during Insert in Visual Block Mode

Try adding this to your vimrc:

nmap <buffer> <silent> <expr> <F12> InsertCol()
imap <buffer> <silent> <expr> <F12> InsertCol()

function! InsertCol()
    let w:first_call = exists('w:first_call') ? 0 : 1
    "if w:first_call
    "    startinsert
    "endif
    try
        let char = getchar()
    catch /^Vim:Interrupt$/
        let char = "\<Esc>"
    endtry
    if char == '^\d\+$' || type(char) == 0
        let char = nr2char(char)
    endif " It is the ascii code.
    if char == "\<Esc>"
        unlet w:first_call
        return char
    endif
    redraw
    if w:first_call
        return char."\<Esc>gvA\<C-R>=Redraw()\<CR>\<F12>"
    else
        return char."\<Esc>gvlA\<C-R>=Redraw()\<CR>\<F12>"
    endif
endfunction

function! Redraw()
    redraw
    return ''
endfunction

Then press Ctrl-vI as usual, and then press F12. It will insert and show all lines changed for each keystroke.

Note: The script would be better if pressing F12 would go into insert mode, instead of requiring you to press I each time. Maybe the startinsert command in combination with vnoremap could do this.
