Is it possible to disable Replace mode in vim?

问题:

Put simply, how can I completely disable Replace mode in vim? I never use Replace mode, but I sometimes end up in it by accident when re-entering Insert Mode. Naturally, I goof up by typing over a few characters before realizing I am in replace mode. So, is there any way to completely disable Replace mode, whether through configuration setup or however?

回答1:

You cannot disable replace mode, but you can make autocommands which will change Replace and Virtual Replace modes back to Insert mode:

function s:ForbidReplace()
    if v:insertmode isnot# 'i'
        call feedkeys("\<Insert>", "n")
    endif
endfunction
augroup ForbidReplaceMode
    autocmd!
    autocmd InsertEnter  * call s:ForbidReplace()
    autocmd InsertChange * call s:ForbidReplace()
augroup END

Not sure if this is the best way, but you could map R and r to nothing in your .vimrc:

map R <C-V><C-V>
map r <C-V><C-V>

Edit: or this:

map R <Nop>
map r <Nop>

Just add in your .vimrc imap <Insert> <Nop>

That will be enough

I found this solution better. Insert key to enter insert mode works, but replace mode on second insert hit is disabled. Place next two lines into your .vimrc

imap <Insert> <Nop>
inoremap <S-Insert> <Insert>

Use I key to go into Insert instead of using the Insert key

That way you will not re-enter Insert mode
