Keyword completion as a fallback for omnicompletion

Hello Vim experts,

for certain filetypes I'd find it convenient to fallback to keyword completion
automatically when omnifunc fails, either because omnifunc is not defined or,
more interestingly, because no omnifunc pattern matches. So far, I have come
up with the following code:


fun! MyComplete()
if strlen(&omnifunc) > 0
let c = call(&omnifunc, [1,''])
if c >= 0
let matches = call(&omnifunc, [0, strpart(getline('.'), c,
col('.') - c)])
if !empty(matches)
return "\<c-x>\<c-o>"
end
end
end
return "\<c-x>\<c-p>"
endf

imap <expr><silent> <tab> pumvisible() ? "\<c-n>" : MyComplete()

This does what I want, but it bothers me that I have to use <c-x><c-o> when
I have already retrieved all the matches. I could use completefunc, but then
I would not know how to return the list that <c-x><c-p> produces (is there
a function for that?).

Do you have any hint on how I could solve this more efficiently?

Thanks,
Life
