Opens fern-rep buffer in a horizontal split, how to avoid it showing up?

[poetaman]

Since some commit, Fern . or perhaps something like Fern . -drawer also opens a fern-rep buffer in a new split (split made in last focussed buffer). How can I disable that from happening? When I had first installed this plugin, it didn't do anything like that (I just want to see drawer, for instance, when I run Fern . -drawer) Thanks!

Here's a GIF that shows the problem:

We have no idea. I performed replace action and did same thing but could not reproduced in Vim/Neovim.

I think, that behavior comes from your configuration.

See https://github.com/lambdalisue/fern.vim/issues/290#issuecomment-769325553 to try fern.vim with minimal vimrc.

@lambdalisue Narrowed down to the following minimal configuration. You should be able to reproduce this behavior with it. (of course update the runtime path to yours)

if exists('+compatible') && &compatible
  set nocompatible
endif

set packpath=
set runtimepath^=~/.vim/plugged/fern.vim/
filetype plugin indent on
syntax on

augroup nofoldonopen
    autocmd!
    autocmd BufWinEnter * normal zR
augroup END

[lambdalisue]

Because R is mapped to rename action in fern. Use normal! instead to make sure Vim's native mapping is used instead like

augroup nofoldonopen
    autocmd!
    autocmd BufWinEnter * normal! zR
augroup END

@lambdalisue Thanks!
