I tried something like this in my vimrc:
set statusline=%F\ [%{bufnr('$')}]
But bufnr('$') only lists the highest existing buffer number, with
smaller-numbered buffers possibly removed by bwipeout...and I don't
want to include, for example, a buffer displaying a help page in the
count. Searching around some more, I found this solution [1]:
set rulerformat=%22(%{g:zbuflistcount};%M%n\ %=%l,%c%V\ %P%)
autocmd BufAdd * let g:zbuflistcount += 1
autocmd BufDelete * let g:zbuflistcount -= 1
autocmd VimEnter * call UpdateZBufLC()
function UpdateZBufLC()
let lst = range(1, bufnr('$'))
call filter(lst, 'buflisted(v:val)')
let g:zbuflistcount = len(lst)
endfunction
Which seems to work fine. I decided against using the fractional count
& just put the total number in the statusline. I find it pretty handy
to be able to tell at a glance how many relevant buffers are open,
then use one of the many available tools [2] for navigating between
them (bufferlist.vim ended up working best for my needs).
