Live Substitution In Neovim

waylonwalker profile image Waylon Walker ・1 min read

Replacing text in vim can be quite frustrating especially since it doesn't have
live feedback to what is changing. Today I was watching Josh Branchaud's
Vim-Unalphabet series on Youtuve and realized that his vim was doing this and I
had to have it.

How to do it.

I had to do a bit of searching and found a great post from vimcasts that shows exactly how to get the live search and replace highlighting using inccomand

:h inccommand

'inccommand' 'icm'  string  (default "")
            global

    "nosplit": Shows the effects of a command incrementally, as you type.
    "split"  : Also shows partial off-screen results in a preview window.

    Works for |:substitute|, |:smagic|, |:snomagic|. |hl-Substitute|

    If the preview is too slow (exceeds 'redrawtime') then 'inccommand' is
    automatically disabled until |Command-line-mode| is done.

Enter fullscreen mode Exit fullscreen mode

Add this to your config

I believe that this is a neovim only feature, add it into your
~/.config/nvim/init.vim file. You can see it in my
dotfiles
as well.

set inccommand=nosplit
Enter fullscreen mode Exit fullscreen mode

See it in Action
