Is the LS broken? After the recent round of updates I can’t seem to get anything out of the LS in VSCode.
1. If I configure my own `julia` executable, it seems I have to do it in two places. Executable path and language-server exe path (is this correct, @pfitzseb ?). But then the LS doesn’t seem able to start (or to work, can’t tell which).
2. If I give consent to having juliaup install the SDK, the proceedings get stuck at “Starting package install”. It is still running, after \>30 minutes.
Can anyone confirm (before I try to report an issue)?
Thanks.

I am using VSCode Julia plugin version 1.170.2 on Linux, and it works fine (well, apart from the known issues).

I tried a different machine. This time `juliaup` apparently installed successfully. The language server does not work, however. It seems to be alive, I do get hover help on Base items
but nothing on other packages

Which Julia version are you using?

Uwe, I noticed that you reported that one of your packages was not getting indexed. Did you ever get it fixed?
Edit: Suddenly the language server started working. I have no idea why ([Dysfunctional language server · Issue #3962 · julia-vscode/julia-vscode · GitHub](https://github.com/julia-vscode/julia-vscode/issues/3962#issuecomment-3707245595)). I did try a few times to force reindexing, and I restarted the language server a few times. Nothing happened. Then I added a currently included package to the current environment, and suddenly I noticed the language server was functional.
I don’t think this can really be considered a solution, but the problem did go away.

Well, the language server is crappy. I am currently testing JETLS.jl, which appears more promising, but it will require a few more months before it is mature enough for daily use.

Damn, I spoke too soon. I opened another project, same problems as before.

I got it to work in emacs by using the latest git master for LanguageServer.jl, SymbolServer.jl, and StaticLint.jl. Supposedly VSCode is supposed to download/build these already, but it’s broken for me on Julia 1.12.3 as well in a similar way as you showed. Some things in base work but most other things do not.
