Tab Vs Space preferences in Vim

Creating a stab option in Vim itself would not be easy, but I’ve whipped up this command/function that you can drop in your .vimrc (or a plugin file if you’re super-organized). Use :Stab and you will be prompted for an indent level and whether or not to use expandtab. If you hit enter without giving it a new indent level, it will just print the current settings.

" put all this in your .vimrc or a plugin file
command! -nargs=* Stab call Stab()
function! Stab()
  let l:tabstop = 1 * input('set shiftwidth=")

  if l:tabstop > 0
    " do we want expandtab as well?
    let l:expandtab = confirm("set expandtab?', "&Yes\n&No\n&Cancel")
    if l:expandtab == 3
      " abort?
      return
    endif

    let &l:sts = l:tabstop
    let &l:ts = l:tabstop
    let &l:sw = l:tabstop

    if l:expandtab == 1
      setlocal expandtab
    else
      setlocal noexpandtab
    endif
  endif

  " show the selected options
  try
    echohl ModeMsg
    echon 'set tabstop='
    echohl Question
    echon &l:ts
    echohl ModeMsg
    echon ' shiftwidth="
    echohl Question
    echon &l:sw
    echohl ModeMsg
    echon " sts="
    echohl Question
    echon &l:sts . " ' . (&l:et ? '  ' : 'no')
    echohl ModeMsg
    echon 'expandtab'
  finally
    echohl None
  endtry
endfunction
