Howto inserting multiline completefunc text?

[Marc Weber]

I want the first completion entering
abc
def

and the second entering
2nd example
2nd lne

How to do this?

example (source this the following lines)

function! CompleteExample(findstart, base)
  if a:findstart
    " locate the start of the word
    let [bc,ac] = vl#lib#buffer#splitlineatcursor#SplitCurrentLineAtCursor()
    return len(bc)-len(matchstr(bc,'\%(\a\|\.\|\$\|\^\)*$'))
  else
      call complete_add( { 'word' : "abc\ndef"
                       \ , 'abbr' : "completion1"
                       \ } )

      call complete_add( { 'word' : "2nd exapmle\n2ndline"
                       \ , 'abbr' : "completion2"
                       \ } )
  endif
endfunction
set completefunc=CompleteExample
