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?
