Improvement for bibtex-ls vim integration

[ashwinvis]

Here is vim configuration that I came up with, which does not require to hard code the bib file name. Notice the globpath which detects bib files in parent, present or child directories

function! Bibtex_ls()
  let bibfiles = (
      \ globpath('.', '*.bib', v:true, v:true) +
      \ globpath('..', '*.bib', v:true, v:true) +
      \ globpath('*/', '*.bib', v:true, v:true)
      \ )
  let bibfiles = join(bibfiles, ' ')
  let source_cmd = 'bibtex-ls '.bibfiles
  return source_cmd
endfunction

function! s:bibtex_cite_sink_insert(lines)
    let r=system("bibtex-cite ", a:lines)
    execute ':normal! i' . r
    call feedkeys('a', 'n')
endfunction

inoremap <silent> @@ <c-g>u<c-o>:call fzf#run({
                        \ 'source': Bibtex_ls(),
                        \ 'sink*': function('<sid>bibtex_cite_sink_insert'),
                        \ 'up': '40%',
                        \ 'options': '--ansi --layout=reverse-list --multi --prompt "Cite> "'})<CR>

Thanks! This looks useful and I’ll add it to the readme.
