^_ shows up at the end of a file name

[narutaro]

I use Mac with vim version 8.2.3489. Wen I launch Fern, ^_ shows up at the end of a file name in the file tree. Any way to remove them?

  |  .zprofile^_                                     
  |  .zsh_history^_   
  |  .zshrc^_ 

.vimrc is as follows.

" vim-plug
call plug#begin()
Plug 'lambdalisue/fern.vim'
call plug#end()

" Show hidden files
let g:fern#default_hidden=1

" Show file tree with Ctrl+n
nnoremap <C-n> :Fern . -reveal=% -drawer -toggle -width=40<CR>

" Color
colorscheme molokai

@narutaro Could you try if #397 solves your issue?

[narutaro]

Hi @lambdalisue, thank you for your quick update. After doing the followings, I still see the ^_. I am not really familiar with this and not sure if I am doing right. Give me your advice.

1. Fetch fix-syntax in plugged

% cd /Users/me/.vim/plugged/fern.vim
% git branch
* fix-syntax
  master

2. Put the fern.vim in autoload

Not sure but prob.

Plug 'lambdalisue/fern.vim', { 'branch': 'fix-syntax' }

[narutaro]

I could not make it work with both vim-plug and jetpack while both of them has fix-syntax branch in the directory...

[lambdalisue]

Hum... Then please create a minimal vimrc.

[brandon1024]

This happens to me anytime I source my vimrc. Closing the drawer and reopening it fixes it for me.

[lambdalisue]

Unfortunately, everybody use different settings so we need a minimal vimrc to reproduce the issue.

[narutaro]

I created the ~/vimrc.min

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

" Disable Vim's native pack feature
set packpath=

" Clone https://github.com/lambdalisue/fern.vim in somewhere
" and specify that directory to the below
" set runtimepath^=~/ghq/github.com/lambdalisue/fern.vim
set runtimepath^=~/min/fern.vim

filetype plugin indent on
syntax on
"----------------------------------------------------------------

" Add extra settings here to reproduce the issue...

"----------------------------------------------------------------
echomsg "Custom minimal vimrc has loaded"

then

% vim -N -u ~/vimrc.min

Now, :Fern . gets:

 me^_

I can also reproduce for Vim 8.2 used in mac Terminal app

This line and the same line in nerdfont plugin are causing above issue
https://github.com/lambdalisue/fern.vim/blob/63b79ab7440095a1adc1c10f2bfdba4ceb46080a/autoload/fern/renderer/default.vim#L88

After deleting the ^_ in suffix . '^_' . a:node.badge, it works. Are you trying to type a space before a.node.badge but somehow it is a special space?

[lambdalisue]

I found that Vim on macOS didn't built with conceal and that cause this issue. Does Vim built with conceal feature?

You are correct. After I rebuilt with conceal, it works.

[narutaro]

It works for me too. Thank you @lambdalisue and @ydzhou!
