Configuration examples for VS Code

There are no details on how to set this up for VS Code.

I tried to set it up, which was relatively easy, but get the error: "Unsupported position encoding (utf-8) received from server Rust Analyzer Language Server". I think this is related to lsp defaulting to utf-16, which can be tracked at vscode-languageserver-node/#1224.

Whatever, the configuration per se is just to add in VSCode's settings.json:

{
    "rust-analyzer.server.path": "/path/to/ra-multiplex",
    ...
}

I don't know If there is a way in the current implementation to specify the lsp to use utf-16 instead of utf-8.

Nvm got it working, but sometimes it still gives the utf-8 error, but it eventually goes away and can use it without problem. So just adding the server path to the settings.json should do it.

vscode already uses only a single rust-analyzer instance per window, adding ra-multiplex into the loop is probably going to cause you more trouble than it's worth, with how heavy the editor alone is you probably don't want to have multiple windows with the same project open.

@pr2502 That's good advice, thanks.

FWIW for me it's still useful because I tend to keep my laptop on but open / close different projects throughout the day depending on what I'm working on.

Rust Analyzer takes forever (up to ~2 min) to start each time I open VSCode on some of the larger projects, so keeping ra-multiplex always in background is still very much worth it.
