If you have a nerdtree file navigation window on the left of the current buffer and use
:bd1, you will find that
the nerdtree window will occupy the whole window.
When you open another buffer, you have to manually resize the nerdtree window to a smaller size, which is super annoying.
How to prevent this behaviour?
An easy way is to switch to another buffer first, and then delete the previous buffer. We can create a shortcut for this:
nnoremap \d :bp<cr>:bd #<cr>
In the above command,
:bp stands for
:bprevious, which will change the buffer to the previous buffer.
# after the
:bd command represents the last used buffer, i.e., the buffer we want to delete.
There is also a Nvim plugin called vim-bufkill, which specifically address this issue. After installing this plugin, you can use
:BD to delete the current buffer without closing the window.
