Rust LSP server never kicks in #421

Open phil1234567891011 opened 1 month ago

phil1234567891011 commented 1 month ago

Hi,

please let me know how to trigger that LSP example

The RustExtension and RustLanguageServerProvider classes never kick in no breakpoint are registered and nothing happens as I drop a .rs or .rust file in visual studio instance

InitializeServices is never called

thanks for your help as this is really a niche feature, I struggle to find answers for this

Hello, did you follow the instructions in the readme?

Especially this section:

This sample requires installing Rust and copying rust-analyzer.exe found under releases named "rust-analyzer-x86_64-pc-windows-msvc.zip" into the project folder.

I did a quick test:

I can hit breakpoints in the extension and I see a successful initialization of the server:

I can also see that multiple LSP features are now active (some quick actions, some errors and warnings, the navigation bar at the top of the document). Please keep in mind that this project is only meant to show how to create an extension that starts an external LSP server executable, it's not meant to provide a fully working LSP server for Rust to be used in Visual Studio.

[edite: I noticed an exception in the output window, see below] yes,

but not a single breakpoint is reachable dropping an .rs file does not trigger anything

I have an exception

I see that you are using VS 17.10 but, looking at the error, I think you are using the VisualStudio.Extensibility 17.11 packages to build the extension. Make sure to use the VisualStudio.Extensibility 17.10 packages if you want to target VS 17.10 and newer. You can find the 17.10 samples in the corresponding branch of this repo.

@phil1234567891011 please confirm that using 17.10 packages fixes this issue. Thanks!

the error is gone, yet the problem persists, nothing happens as I drag drop a file in VS and no breakpoints are reachable
