Vim Terminal interferes with statusline

Question

I am editing a lot of files with Vim, and I have the following in my .vimrc to help me stay oriented as to which file I am in:

" Add file name to statusline so we know where we are in the slideshow
set statusline+=%f

I recently started using mdless to render the Markdown files in Vim Terminal (:terminal); it's working great except Terminal overwrites my statusline setting. Is there way to keep Terminal's paws off the statusline? :)

The built-in help on Terminal says:

In Terminal-Normal mode the statusline and window title show "(Terminal)". If the job ends while in Terminal-Normal mode this changes to "(Terminal-finished)".

It's hard to believe this isn't configurable... just about everything else is. :)

How to reproduce

Given a file vimrc with the following content:

" Make status line visible
set laststatus=2
" Add file name to statusline so we know where we are in the slideshow
set statusline+=%f

Start vim using this vimrc:

vim -u vimrc vimrc

and it will show "vimrc" on a status line, on 2nd line from the bottom.

Now run:

:term++curwin cat vimrc

and that changes that 2nd line from the bottom to say

!cat vimrc [finished]                                                                                                                                 

Also its color changes, from white to green.

Answer 1

This is just normal. %f stands for current buffer's name (:h bufname()) and it gets inserted as is, i.e. !cat vimrc, plus status, i.e. [finished].

To change terminal's buffer name

 call term_start('cat vimrc', {'term_name': 'foobar'})

To setup status line for terminal windows only

augroup test | au!
    autocmd TerminalWinOpen * setlocal statusline=foobar
augroup end

The colors are also per default. For regular buffers it's StatusLine/StatusLineNC, and for terminal buffers - StatusLineTerm/StatusLineTermNC.

To change your colorscheme

colorscheme foobar

To change individual highlighting group settings

augroup test | au!
    autocmd ColorScheme * hi! link StatusLineTerm StatusLine
    autocmd ColorScheme * hi! link StatusLineTermNC StatusLineNC
augroup end

To overwrite highlighting group by status line

set statusline=%#StatusLine#%f
