Incompatibility with goyo.vim

[DenisLug]

When I use instant-markdown with goyo.vim, I get strange characters at the top of the editor like these:
^[[2;2R^[[>65;5403;1c^[]10;rgb:ffff/ffff/ffff^[\^11;rgb:0000/0000/0000^[\

Also the preview stays often times blank. Is there a way to use instant-markdown together with goyo?

Surprised to find this here as well. I've experienced issues where character buffer does not update properly in vim when using goyo.vim. I ended up uninstalling instant-markdown. It would be nice to see resolution to this problem.

vim-instant-markdown simply sends lines to a node.js server, it does not write into vim. I use Goyo, but I cannot reproduce the issue. Can you share the plugins that you use and a screenshot?

[MinhyukPark]

Yeah I’ll get on that tomorrow. I didn’t do any kind of debugging or log checking when it happened so I might not be able to reproduce the issue.

[MinhyukPark]

ok I finally got some time to get to this.

It could be a Goyo issue as well but here is the best way I was able to localize the issue. When you type fast enough, the screenbuffer shows duplicate characters but when you exit Goyo everything is ok.

Feel free to ask me for anything extra or some testing you want me to do. I can't promise that I can get to them right away but I'm willing to help debug.

I'm on vim 8.1 with 1-1073 patches, compiled huge without gui. Just the default huge compile options.
This happens on both vim, nvim, and both on ubuntu 18.04 and arch as far as I can tell.

When I was trying to reproduce this, the only plugins I was using were vundle, vim-monokai, and goyo.

I use Goyo, but I don't get this. It seems unlikely that this issue relate to us. Keeping this open anyways, if someone has any hint.

I also have this issue. I created this gif to show what I'm experiencing. Please excuse the quality.

(,jo is how i enter goyo-mode)

This is Git bash on windows. Might be why I have issues.

Thanks for taking that effort to screencap the issue. I tried to make a minimal.vimrc:

set nocompatible
filetype off

call plug#begin('~/.vim/plugged')
Plug 'junegunn/vim-plug'
Plug 'junegunn/goyo.vim', {'for': ['tex', 'text', 'markdown', 'markdown.pandoc', 'rst'], 'on': 'Goyo'}
Plug 'instant-markdown/vim-instant-markdown', {'for': ['markdown', 'markdown.pandoc']}
call plug#end()

filetype plugin indent on
syntax enable
set nomore
set noswapfile
set viminfo=

function! s:goyo_enter()
  silent !tmux set status off
  silent !tmux list-panes -F '\#F' | grep -q Z || tmux resize-pane -Z
  set noshowmode
  set noshowcmd
  set scrolloff=999
endfunction

function! s:goyo_leave()
  silent !tmux set status on
  silent !tmux list-panes -F '\#F' | grep -q Z && tmux resize-pane -Z
  set showmode
  set showcmd
  set scrolloff=5
endfunction

autocmd! User GoyoEnter nested call <SID>goyo_enter()
autocmd! User GoyoLeave nested call <SID>goyo_leave()

And I do not get this. I am using:

Could you try to debug using the minimal vimrc and open it as follows, using vim / nvim:

$ nvim -u minimal.vimrc test.md

Might be a problem with junegunn/limelight actually...

Try this vimrc:

set nocompatible
set t_Co=256 " Added this <----
filetype off

call plug#begin('~/.vim/plugged')
Plug 'junegunn/vim-plug'
Plug 'junegunn/limelight.vim' " Added this
Plug 'junegunn/goyo.vim', {'for': ['tex', 'text', 'markdown', 'markdown.pandoc', 'rst'], 'on': 'Goyo'}
Plug 'instant-markdown/vim-instant-markdown', {'for': ['markdown', 'markdown.pandoc']}
call plug#end()

filetype plugin indent on
syntax enable
set nomore
set noswapfile
set viminfo=

function! s:goyo_enter()
  silent !tmux set status off
  silent !tmux list-panes -F '\#F' | grep -q Z || tmux resize-pane -Z
  set noshowmode
  set noshowcmd
  set scrolloff=999
endfunction

function! s:goyo_leave()
  silent !tmux set status on
  silent !tmux list-panes -F '\#F' | grep -q Z && tmux resize-pane -Z
  set showmode
  set showcmd
  set scrolloff=5
endfunction

autocmd! User GoyoEnter nested call <SID>goyo_enter()
autocmd! User GoyoLeave nested call <SID>goyo_leave()

fun! ToggleJournal()
    " Color name (:help cterm-colors) or ANSI code
    let g:limelight_conceal_ctermfg = 100

    " Color name (:help gui-colors) or RGB color
    let g:limelight_conceal_guifg = '#83a598'

    execute 'Goyo'
    execute 'Limelight!!'
endfun

let g:mapleader = ","
:command! Journal :call ToggleJournal()
nnoremap <leader>jo :call ToggleJournal()<CR>

Added a function and some mappings. t_Co at the second line and then the vim-plug declaration for limelight.

Tried that too. I cannot reproduce it. As you said it might be OS dependent. I am leaving it for someone interested to fix.
