Boost Your Coding Efficiency with GitHub Copilot and Copilot Labs

GitHub Copilot

GitHub Copilot is an AI‑powered code completion assistant built on OpenAI’s GPT models. It can generate code from natural‑language comments or partial snippets, supports many languages (Python, JavaScript, TypeScript, Go, PHP, etc.), and integrates with a wide range of development environments.

Supported IDEs

IntelliJ IDEA (Ultimate, Community, Educational)

Android Studio

AppCode

CLion

Code With Me Guest

DataGrip

DataSpell

GoLand

JetBrains Client

MPS

PhpStorm

PyCharm (Professional, Community, Educational)

Rider

RubyMine

WebStorm

Installation

Install the GitHub Copilot extension for the chosen IDE (e.g., VS Code, JetBrains IDEs).

Verify that Copilot is functional in the editor.

Apply for the Copilot Labs preview at https://githubnext.com/projects/copilot-labs and obtain access.

In VS Code, search the Marketplace for “GitHub Copilot Labs” and install the extension.

Copilot Labs Features

Automatic code generation from keywords and context.

Inline code completion suggestions.

Language translation (e.g., PHP → Lua).

Automatic code commenting.

Code refactoring and optimization.

Static analysis and bug‑finding.

Automated unit‑test generation (currently JavaScript only).

Example: Generating a bubble‑sort function

function bubbleSort(arr) {
    const n = arr.length;
    for (let i = 0; i < n - 1; i++) {
        for (let j = 0; j < n - i - 1; j++) {
            if (arr[j] > arr[j + 1]) {
                // swap
                const temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
            }
        }
    }
    return arr;
}

The generated function follows the classic bubble‑sort algorithm: it iterates over the array, repeatedly swapping adjacent out‑of‑order elements until the list is sorted.

Prompt Presets (Advanced Options)

Custom : Provide a free‑form natural‑language prompt to generate tailored code.

Explain code : Ask the model to describe selected code in Chinese (or any language).

Code does following : Receive a detailed step‑by‑step explanation of what the code does.

Show example code : Generate a usage example for the produced function.

READABLE : Rewrites code to improve readability.

ADD TYPES : Adds strong type annotations (e.g., TypeScript types or PHP type hints).

FIX BUG : Attempts automatic bug fixes based on static analysis.

DEBUG : Inserts console‑log or debugger statements to aid debugging.

LIST STEPS : Annotates each line with explanatory comments.

MAKE ROBUST : Enhances error handling and edge‑case coverage.

CHUNK : Splits large code blocks into smaller, manageable pieces.

TEST GENERATION : Generates test cases; currently limited to JavaScript projects.

Usage Notes

Copilot Labs is still in preview; access requires applying for the preview program. Test generation works only for JavaScript environments, and the generated tests assume the project has the necessary testing framework installed.
