Language Server Plugin for CodeMirror 6

This plugin enables code completion, hover tooltips, and linter functionality by connecting a CodeMirror 6 editor with a language server over WebSocket.

How It Works

Usage

npm i codemirror-languageserver

import { languageServer } from 'codemirror-languageserver';

const transport = new WebSocketTransport(serverUri)

var ls = languageServer({
	// WebSocket server uri and other client options.
	serverUri,
	rootUri: 'file:///',

	// Alternatively, to share the same client across multiple instances of this plugin.
	client: new LanguageServerClient({
		serverUri,
		rootUri: 'file:///'
	}),

	documentUri: `file:///${filename}`,
	languageId: 'cpp' // As defined at https://microsoft.github.io/language-server-protocol/specification#textDocumentItem.
});

var view = new EditorView({
	state: EditorState.create({
		extensions: [
			// ...
			ls,
			// ...
		]
	})
});
