Does autocomplete work for imported modules?

What do you mean?

[graydotnet]

Autocomplete does not seem to work with clangd in vscode. When I have a module and import it in another source file, the symbols from the imported module aren't exposed in autocomplete.

This is not expected. Even if the upstreaming clangd, you can enable it by --experimental-modules-support. And the clangd in this repo enable this option by default.

I am using LLVM 19.1.0-rc3.

Here is a repo: https://gist.github.com/graydotnet/0882f40fc5848b7cfc66f7ff1392a5c1

If you start typing "he" in the function try_autocomplete_here, it does not autocomplete the namespace "hello". Similar if you have "hello::s", "hello::say" is not autocompleted.

Yeah, it looks like it is true that autocompletion doesn't work well.

It can only work basically to show the signature but not the autocompletion.

Given this repo is majorly for speeding up, I think we can raise the issue in clangd's bug tracker: https://github.com/clangd/clangd/issues
