How can I close a buffer without closing the window?

Question

Vim\'s multilayered views (Windows, Buffers and Tabs) left me a little confused. Let\'s say I split the display (:sp) and then select a different buffer to display in each w

Answer 1

nmap d :bprevious:bdelete #

Works as it should until one buffer is open in several windows. Good enough unless you want to use the bigger scripts out there.

Edit: this is what i use right now:

function! BufferDelete()
    if &modified
        echohl ErrorMsg
        echomsg "No write since last change. Not closing buffer."
        echohl NONE
    else
        let s:total_nr_buffers = len(filter(range(1, bufnr('$')), 'buflisted(v:val)'))

        if s:total_nr_buffers == 1
            bdelete
            echo "Buffer deleted. Created new buffer."
        else
            bprevious
            bdelete #
            echo "Buffer deleted."
        endif
    endif
endfunction
