[vim/vim] autocomplete: how to get the first menu item selected (as if `<C-n>` was pressed then)? (Discussion #18340)
Tomasz N
Thanks to #18329 we have consistently selected no items resulted from autocomplete. I'm not sure if it's correct without noselect so ask here.
If so, is it possible to get the first menu item selected (as if <C-n> was pressed then)?
The below example is almost copied from #18326:
Let file /tmp/words consist of
v
vi
vim
- run
vim --clean -c 'se ac completeopt=menuone,noinsert,fuzzy' -c 'normal G' -c 'startinsert' /tmp/words - type
v(no item selected)
Expected result:

It’s not entirely clear what you want. Are you asking to have the first item inserted automatically? That isn’t possible, since <BS> wouldn’t work in that case. However, you can enable preinsert, which will select the first item for you. This option doesn’t work as expected yet, but I plan to implement it soon.

I would be interested with preinsert, but it does not work with fuzzy.
Currently we need to press <C-n> to get the first menu item active. I'd like to have it done automatically (and then get CompleteChanged event too).
It seems that we have no autocommand notifying when the menu is displayed.
The simple autocommand
au ModeChanged *:ic call feedkeys("\<C-n>")
seems to be not useful:
<C-n>may be entered too early, i.e. whileaclis still pending- in other cases I get redundant (additional)
<C-n>
I'm not sure if autoinserting <C-n> enough late would give me any useful result, but wanted to see what fails in such case.
Writing this comment I played with:
set autocomplete set autocompletedelay=300 set completeopt=menuone,noinsert,fuzzy set cpt+=k/usr/share/dict/american-english au ModeChanged *:ic call feedkeys("\<C-n>") startinsert

Forgive me for still being a bit confused about completeopt. If is true that autocomplete implicitly enables noselect (especially after making consistence in #18329), then maybe it is worth documentation.

autocomplete automatically applies noselect unless you include preinsert.

If I've missed something, it would be worth documenting.

It is documented in :h cot in maybe not a clear way:
Only "fuzzy", "popup", "popuphidden", "preinsert" and "preview" have
an effect when 'autocomplete' is enabled.

There is no noselect 😉 Even if it were there, it would sound like an option that depends on being enabled manually, whereas, as you mentioned, currently it is forced by autocomplete (except with preinsert).

Can you write a draft of enhanced help document? I think you have a point. I can review it and include it.
