Deleting a buffer without closing the window
From Vim Tips Wiki
You may use the
:vsplit commands to display several windows, with some windows showing different parts of one buffer, while other windows show other buffers.
When finished with a buffer, you can close it with the
:bdelete command. However, that command will also close all windows currently showing the buffer.
The script below defines the
:Bclose command that deletes a buffer, while keeping the current window layout (no windows are closed).
:Bclose command deletes a buffer without changing the window layout. For each window where the buffer is currently displayed:
- Show the alternate buffer (
:buffer #), if any.
- Otherwise, show the previous buffer (
:bprevious), if any.
- Otherwise, show an empty buffer.
- Close buffer in current window.
- Close buffer number N (as shown by
- Close buffer named Name (as shown by
Assuming the default backslash leader key, you can also press
\bd to close (delete) the buffer in the current window (same as
:Bclose will fail if the buffer has been modified. You can append
! to discard all changes (for example,
:Bclose! will delete the buffer in the current window; any changes to the buffer are lost).
:Bclose will close a buffer even if it is displayed in multiple windows (the windows are not closed). Put the following in your vimrc if you would prefer that a buffer is not closed if it is displayed more than once:
:let bclose_multiple = 0

 Alternative Script
Below, I have a new, more complicated version of above script. The below script will actually create a scratch buffer if there are no listed buffers left. The script, in addition, takes care of a small annoyance. Before, if you 1) open vim, 2) :e a file, 3) :bd, 4) :e the same file, then there will be two buffers listed (that file and a [no name] buffer). The following script ensures this doesn't happen.
Everything in this tutorial assumes the user does "set hidden".
Using this Kwbd command (
:Kwbd) will make Vim windows behave more like an IDE, or maybe even better. You can also setup a mapping, see the end of the script.
"here is a more exotic version of my original Kwbd script "delete the buffer; keep windows; create a scratch buffer if no buffers left function s:Kwbd(kwbdStage) if(a:kwbdStage == 1) if(!buflisted(winbufnr(0))) bd! return endif let s:kwbdBufNum = bufnr("%") let s:kwbdWinNum = winnr() windo call s:Kwbd(2) execute s:kwbdWinNum .

For getting asked what should be done, when a file has been modified I use normally
:confirm :bd. So I changed the script in 2lines to achieve this:
if empty(a:bang) && getbufvar(btarget, '&modified') call s:Warn('No write since last change for buffer '.btarget.' (use :Bclose!)') " return endif ... endif endfor " execute 'bdelete'.a:bang.' '.btarget execute ':confirm :bdelete '.btarget execute wcurrent.'wincmd w'
Just comment out the return and replace the command. greetings - Joe
