Hi guys,

VIM has an option tabline that one can use to configure how the tab line would look like. Back when I used to use gvim, I could very easily manipulate how the text on the tab looked like by setting the guitablabel setting, however tabline is not all that easy to configure.

Here is what I use now :

function! MyTabLine()
  let s = ''
  for i in range(tabpagenr('$'))
    let tabnr = i + 1 " range() starts at 0
    let winnr = tabpagewinnr(tabnr)
    let buflist = tabpagebuflist(tabnr)
    let bufnr = buflist[winnr - 1]
    let bufname = fnamemodify(bufname(bufnr), ':t')

    let s .= '%' . tabnr . 'T'
    let s .= (tabnr == tabpagenr() ? '%#TabLineSel#' : '%#TabLine#')
    let s .= ' ' . tabnr

    let n = tabpagewinnr(tabnr,'$')
    if n > 1 | let s .= ':' . n | endif

    let s .= empty(bufname) ? ' [No Name] ' : ' ' . bufname . ' '

    let bufmodified = getbufvar(bufnr, "&mod")
    if bufmodified | let s .= '+ ' | endif
  endfor
  let s .= '%#TabLineFill#'
  return s
endfunction
set tabline=%!MyTabLine()

This is what it looks like :
