In Neovim, when I type :%s/foo then the current buffer changes to have all instances of foo removed, basically giving a preview of the change. Coming from standard Vim, I find this confusing and it's also very slow for large files. How can I disable this behavior?

Set :h inccommand to an empty string.

let &inccommand = ""

From :h inccommand:

When nonempty, inccommand, shows the effects of :substitute, :smagic, :snomagic and user commands with the :command-preview flag as you type.

  • Great, thanks! I noticed another very related issue and thought you might have an idea (otherwise I'll start a new question)? When I type /foo it nicely highlights all matches and doesn't change the scroll position but when I do :%s/foo then it scrolls to the first match even while I'm still typing. Is there a way to instead scroll to the next match (just like /foo)?

    First: the reason any search (including substitute) command scrolls is because of :h incsearch. If you search for a word which is outside the current view of the window, it will scroll. Second: the reason %s/foo scrolls differently from /foo is because you are matching from the beginning of the file, not from current line downward. The behavior you're asking for can be achieved with :,,$s/foo (see :h :range). But that would of course only substitute from the current line to the last line; not the whole buffer. If you think about it, it makes sense.
