Hi friends,
there are multiple select-able proposals when I use multiple acceptor.accept(proposal),
is there any way to know which option has been selected or even know there is one has been selected?

Thanks ~

Hi,

what is your question behind this question?
why do you ask?

when the editor offers the proposals, user can choose not to select any.
My point is:
the proposal only applies when there is no one has been selected.
for instance,
XXsomethingXX <somthing which can be selected from proposals> (if selected, then ctrl+space won't trigger any proposal again after that, if I cannot know which proposal has been selected, I need to check part within <> to ensure that)

Maybe i am just a little confused. Embarrassed

Hi sorry I still don't know why you need to check. Could you come up
with a real world example

for another example:
if i have pseudo-grammar : component.resource operation-option
operation-option can be set() or add().
when user select set can get C.R set("a")<if ctrl+space after this won't trigger any proposal, so there is no more operation when one has been picked>

I am not sure it is clear enough

Hi you should fix this upfront and filter the proposals on creation.
The methods in the proposal provider (or even scoping) should you
offer enough context to detect this situation

Then i need to determine the proposals myself.
thanks.

BTW, What is the exact functionality of scoping? i know it is about cross reference.
So if there is no cross reference in my grammar, then there is no need to customize the scoping. Am i right?

Thanks
