How to implement "Go To Definition" extension in VSCode

Question

Which method in vscode-languageserver::IConnection has to be implemented to provide functionality "Go To Definition" over multiple files?

I was studying Language Server Node Example and vscode "API documentation", but I didn't find any info.

Answer 1

The following code snippet illustrates how to implement "Go To Definition" using vscode-laguageserver.

connection.onInitialize((params): InitializeResult => {
    ...
    return {
        capabilities: {
            definitionProvider: true,
            ...
        }
    }
});

connection.onDefinition((textDocumentIdentifier: TextDocumentIdentifier): Definition => {
    return Location.create(textDocumentIdentifier.uri, {
        start: { line: 2, character: 5 },
        end: { line: 2, character: 6 }
    });
});
