R Language Server for Ace Linters

This page provides detailed instructions on how to integrate and use the R language server with Ace Linters in the Ace Editor. The R language server brings features like autocompletion, syntax checking, and diagnostics to R programming in the Ace environment.

Introduction

The R language server enhances the functionality of editing R scripts by providing real-time code analysis and features that are essential for productive R programming. This includes support for code completion, function signature information, and real-time diagnostics.

Installation

1. Prerequisites: Ensure you have R installed on your system. You can download it from the official R project website.
2. Install R Language Server: Open an R console and install the language server package by running:

   install.packages("languageserver")

Configuration

To configure the R language server with Ace Linters, set up your Ace Editor environment to connect to the R language server through a WebSocket. Below is an example configuration:

let server = [
    {
    module: () => import("ace-linters/build/language-client"),
    modes: "r",
    type: "socket",
    socket: new WebSocket("ws://127.0.0.1:3030/r"), //in case you are using Language Server WebSocket Bridge
}];

Ensure that the R language server is running on the specified WebSocket port. For setting up the WebSocket server for R, you can use tools like Language Server WebSocket Bridge for integrating multiple language servers.

Usage Examples

Here’s how to set up a basic editor instance with the R language server in Ace Linters:

import * as ace from "ace-code";
import {AceLanguageClient} from "ace-linters/build/ace-language-client";

// Configure the editor with R mode
let editor = ace.edit("editor", {
    mode: "ace/mode/r",
    enableBasicAutocompletion: true,
    enableLiveAutocompletion: true
});

// Connect to the R language server via the configured language provider
let provider = AceLanguageClient.for(server);
provider.registerEditor(editor);

Troubleshooting

• Connection Issues: Check if the WebSocket server for the R language server is properly set up and running.
• Feature Limitations: Some features might not perform optimally in the browser due to network delays or configuration issues.
