Lightline.vim: Bufferline and statusline lose highlight color on Save

[spiritphyz]

Hi, I am also seeing the behavior of “saving buffers will cause the tab bar and statusline to lose their highlight colors” (same as: https://github.com/itchyny/lightline.vim/issues/400)

If I have 3 “tabs” open, then saving the buffer on the first tab will not lose highlight colors. However, if I save the buffers on the 2nd or 3rd tab, then the highlight colors are lost on save.

Here is my init.vim:

" === Lightline options ===
set laststatus=2
set noshowmode " turn off extra -- INSERT --

" Change colors to be darker for status bar and tab bar
let g:lightline = {
      \ 'colorscheme': 'darcula',
      \ }

let g:lightline.component_expand = {
      \  'buffers': 'lightline#bufferline#buffers',
      \  'linter_checking': 'lightline#ale#checking',
      \  'linter_warnings': 'lightline#ale#warnings',
      \  'linter_errors': 'lightline#ale#errors',
      \  'linter_ok': 'lightline#ale#ok',
      \ }

let g:lightline.component_type = {
      \     'buffers': 'tabsel',
      \     'linter_checking': 'left',
      \     'linter_warnings': 'warning',
      \     'linter_errors': 'error',
      \     'linter_ok': 'left',
      \ }

" === Lightline-bufferline options ===
set showtabline=2
let g:lightline#bufferline#filename_modifier = ':t' " only filename, no path
let g:lightline#bufferline#show_number  = 1
let g:lightline#bufferline#shorten_path = 1
let g:lightline#bufferline#unnamed      = '[No Name]'
let g:lightline#bufferline#unicode_symbols = 0
let g:lightline#bufferline#enable_devicons = 1
let g:lightline#bufferline#min_buffer_count = 2
let g:lightline.tabline = {'left': [['buffers']], 'right': [['close']]}

The output of :au BufWrite:

coc_nvim  BufWritePre
    *         call s:SyncAutocmd('BufWritePre', +expand('<abuf>'))
BufWritePre
    *         :%s/\s\+$//e

The output of au: BufWritePost:

myvimrc  BufWritePost
    init.vim  so $MYVIMRC | if has('gui_running') | so $MYGVIMRC | endif
    plugins.vim
              so $MYVIMRC | if has('gui_running') | so $MYGVIMRC | endif

I’m using Neovim v0.5.0-245-g1bfccf028 on Ubuntu 18.04.

Thank you for any insight on helping to solve this issue!

The problem is your myvimrc BufWritePost. If you have something like

autocmd BufWritePost init.vim so $MYVIMRC | if has('gui_running') | so $MYGVIMRC | endif
autocmd BufWritePost plugins.vim so $MYVIMRC | if has('gui_running') | so $MYGVIMRC | endif

then add ++nested attribute like;

autocmd BufWritePost init.vim ++nested so $MYVIMRC | if has('gui_running') | so $MYGVIMRC | endif
autocmd BufWritePost plugins.vim ++nested so $MYVIMRC | if has('gui_running') | so $MYGVIMRC | endif

Wow, that is some amazing troubleshooting, thank you for finding the cause!

I had this in my init.vim file:

" Watch for changes in .vimrc and auto reload
" http://superuser.com/questions/132029/how-do-you-reload-your-vimrc-file-without-restarting-vim
augroup myvimrc    
  au!
  au BufWritePost init.vim,plugins.vim so $MYVIMRC | if has('gui_running') | so      
$MYGVIMRC | endif
augroup END

From your suggestion, I made this change:

augroup myvimrc    
  au!
  au BufWritePost init.vim,plugins.vim ++nested so $MYVIMRC | if has('gui_running') | so      
$MYGVIMRC | endif
augroup END

Now, the problem is fixed, thank you so much!
