Better Auto complete

[am0o0]

Hi, it would be great when we are typing predicate/class names during query writing there is a better search algorithm for the auto complete popup, I'm facing following problems everyday:
searching for module/class names after typing a letter like ::letter is not same/good like searching algorithm for predicate
sometimes the .letter doesn't show any suggestions like when I write a uppercase letter as a first letter search to look for suggestion.(e.g. in picture I want to find getALocalSource but there isn't any suggestion for that)

typing get will give us getALocalSource but the only thing that I know is that I want a predicate with name Local

here I can't reach getALocalSource after typing Lo

the module class names are more critical for me some times the DataFlow::Class is what I want to start work with it.

I wanted to search for word State in previous screenshot but I had to try Flow to find it!

I want to search for a predicate with word Source/source in it

I can't !

but it is popped up now!

However it is like a bug for me it can be an enhancement too, I believe you know about this but when someone out of CodeQL std lib developers want to write a query it is really annoying, lead to Decreased performance and confusion because sometimes I know there should be a class/predicate with a name but I can't see that in auto complete popup!

I'd like to mention @spaceraccoon blog post too.
if you read this blog post you can find out that making auto complete popup more verbose can help a lot to security researchers spend much less time to search in documents.

Thank you for writing up your findings and documenting with screenshots.

@kaspersv is making some adjustments to autocomplete this week, and I think they'll address some of the problems you've raised here, so I've assigned @kaspersv. Let's see at the end of this week what's left and whether it makes sense to create new issues or keep this one.

The work is on pause at the moment because of summer holidays.

Thanks for the improvement suggestion/bug report, @amammad!

I've merged a change to our language server that switches from server-side prefix filtering of autocomplete suggestions to client-side filtering. When autocompletion is triggered in a context such as source.Lo we thus send all possible autocompletions (i.e., independent of the prefix) to the client (VS Code) and let the client handling search & filtering. This should give you the desired autocompletion behaviour.

The change is scheduled for release with CodeQL v. 2.14.2 around mid-August.

I will close this issue for now. Feel free to reopen the issue or create a new issue, if the issue has not been fully addressed.

Wow thanks a lot @kaspersv !
