Gopls Language Server for Ace Linters

This page provides detailed instructions on how to integrate and use the Gopls language server with Ace Linters in the Ace Editor. Gopls offers advanced features for the Go programming language, such as autocompletion, code navigation, and diagnostics.

Introduction

Gopls, the official language server for the Go programming language, provides essential features that enhance coding efficiency in Go. This includes support for code completion, jump to definition, and error checking.

Installation

1. Prerequisites: Ensure you have Go installed on your system. You can download it from the official Go website.
2. Install Gopls: Open a terminal and install Gopls by running:

   go install golang.org/x/tools/gopls@latest
   

Configuration

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

let server = [
    {
    module: () => import("ace-linters/build/language-client"),
    modes: "golang",
    type: "socket",
    socket: new WebSocket("ws://127.0.0.1:3030"),
}];

[!]Ensure that Gopls is running on the specified WebSocket port. You could use Go Language Server WebSocket Proxy (if you need only single language server) or Language Server WebSocket Bridge for multiple language servers

Usage Examples

Here’s how you can set up a basic editor instance with Gopls in Ace Linters:

import * as ace from "ace-builds";
// Configure the editor with Go mode
let editor = ace.edit("editor", {
    mode: "ace/mode/go",
    enableBasicAutocompletion: true,
    enableLiveAutocompletion: true
});

// Connect to Gopls via the configured language provider
var provider = LanguageProvider.fromCdn("https://www.unpkg.com/ace-linters@latest/build/");
provider.registerEditor(editor);

Troubleshooting

• Connection Issues: Ensure the WebSocket server for Gopls is correctly configured and running.
• Feature Limitations: Some features may not perform optimally in the browser due to network latency or configuration mismatches.
