What's the required steps to setup monaco-languageclient?

[Tnze]

After #583, I already established the connection between language server and this package.

But it doesn't seem to be working:

I think I didn't configure monaco-languageclient in the right way. But I don't know how to find the problem.

I suspect that's because I configured monaco-editor first, and introduce monaco-languageclient later. So I didn't call the right setup function. For example, I call monaco.editor.create instead of createConfiguredEditor from vscode/monaco, does it matter? I also tried to use createConfiguredEditor but it doesn't work too.

I also have highlight working before introducing monaco-languageclient, so it also maybe is the pnpm overrides doesn't work property?

The current situation leaves me with no clue. I would be very grateful if someone could provide any ideas.

Hi @Tnze can you share your code or provide an example in a separate GitHub repository? Thank you

Hi, I add the access for you for my private repo (It's not yet ready to public).
To run the project you may want to follow the Tauri Guide

Thank you, I received it. I won't be able to look it at deeply today, but in the upcoming days.

I got the lsp functions working! By add this line:

monaco.languages.register({ id: 'c', aliases: ['c'] })

But highlight is still missing. I guess some override service are needed.

Hey @Tnze,

I'm working on something similar with Tauri and Monaco, I also want to remove the WS server and use Tauri IPC instead, can you share how you connected the Monaco frontend with an ls via Tauri IPC?

It'll help me a lot.

Thanks

I provide a 'connect' command for the frontend. When calling this command, a lsp process is launched, and a numerical "session id" is returned. Two event are used after the session is created: lsp-msg-in-{session_id} and lsp-msg-out-{session_id}. Two tokio routine is spawned to copy the messages in and out. Another tokio routine is spawned and waiting the lsp process exit and send another event lsp-close-{session_id}.

Thanks @Tnze,

What about the frontend? Did you implement IConnectionProvider as you've mentioned in your previous discussion?
Do you manually emit lsp events?

Yes, I extends AbstractMessageReader and implements MessageReader, extends AbstractMessageWriter and implements MessageWriter.

export async function createTauriMessageConnection(encoding: string) {
    if (encoding != 'utf8') throw "Unsupported encoding " + encoding
    const session = await invoke('connect') as number
    const reader = new TauriMessageReader(session)
    const writer = new TauriMessageWriter(session)
    return {
        reader: reader as MessageReader,
        writer: writer as MessageWriter,
    }
}

    languageClient = new MonacoLanguageClient({
        // .....
        connectionProvider: {
            get: createTauriMessageConnection
        }
    });

Thank you, very much appreciated.
