How can I open a temporary "full-size" window inside another window in a tab to execute `:term`?

Question

In order to execute :term in nvim without causing the current window in a tab to close on exit, I execute the following command:

:vnew +term

This splits the current window into two, one of which executes :term.

However, I really don't want to split the window, I just want to open a temporary window, inside the original window in a tab, to execute :term, so that when :term exits, I return to the original window.

Is that possible?

Answer 1

In general that is how tab pages work in vim/neovim:

Excerpt from neovim help (:h :tabc and then one pageup):

CLOSING A TAB PAGE:

Closing the last window of a tab page closes the tab page too, unless there is
only one tab page.

When you have term as the only window in a tab page and "exit" it you close the last window.

I don't know your use case, but maybe floaterm might be useful? If not as a plugin to use right away then maybe as inspiration to use rather big floating window with terminal inside?
