Re: vim: toggle between tabs and toggle between buffers

thanks Paul, your code is nearly perfect!

after some test this is the one that done all works well -- just use standard gt, gT, or Ngt to do all work with regardless of tab and buffer 

function! s:nswitch (n)

  if tabpagenr("$") > 1

    if a:n > 0

        exe "tabnext" a:n

    else

        exe "tabnext"

    endif

  else

    if a:n > 0

        exe "buffer" a:n

    else

        exe "bn"

    endif

  endif

endfunction

noremap <silent> gt :<C-U>call <SID>nswitch(v:count)<CR>

for completeness, similarly use ,l to toggle 2 tabs (if there exists multiple tabs) or 2 buffers (if there is one tab)

function! s:switch()

  if tabpagenr("$") > 1

    exe "tabnext" g:lasttab

  else

    b #

  endif

endfunction

noremap <silent> ,l :call <SID>switch()<enter>

plus, to make the buffer looks even more like a tab, I installed bailey ling's vim-airline plugin:

https://github.com/bling/vim-airline

now there is no diffs between tabs/buffers operations :)

just another (non)related question:

is there a way to display multiple rows of tabs? 

tab is visually much better than buffers, and that's quite useful when handing multiple files -- especially the time when you need multiple files displayed in front of you so you can quickly jump back and forth when you look at the names ... 

but some google research shows "there is no way to display multiple rows of tabs unless modifying the VIM source code" -- means VIM don't support this, right?

Do this:

    function! s:nswitch (n)
      if tabpagenr("$") >= a:n
        exe "tabnext" a:n
      else
        exe "buffer" a:n
      endif
    endfunction

    noremap <silent> gt :<C-U>call <SID>nswitch(v:count)<CR>

Now Ngt goes to tab N if it exists, to buffer N otherwise.

Best,
Paul
