How to keep the neovim terminal buffer in the buffer list even after it being hidden

Question

My problem is similar to, if not same as, this issues. But I can't follow what they're talking about.

The following steps are necessary to reproduce my problems:

:sp
:term
:wincmd w
:wincmd o
:ls

And you'll see that the terminal buffer has disappeared. Any idea why it happens and how to keep the terminal buffer present/alive in the buffer list even after it has been hidden?

Edit I know about :set hidden. But I don't like how it hides buffers yet to be written to disks. I want to use autocmd to modify the neovim terminal buffer so that it can't be hidden at all.

Answer 1

Put the following in ~/.config/nvim/init.vim:

augroup custom_term
    autocmd!
    autocmd TermOpen * setlocal bufhidden=hide
augroup END

I don't know if it's enough, but it is working for now. Check the part with bufhidden=hide, this makes only the terminal buffer hidden when not loaded on any split/window. I don't know if I have to change any other options like :h buflisted or :h buftype and thus leaving this post open for anyone to comment.
