How to Send a Windows Notification Using Lua: A Step-by-Step Guide

Are you wondering how to send a Windows notification using Lua? You're not alone. Many programmers have faced this challenge, especially when transitioning from languages like Python that offer built-in functionalities for notifications. In this post, we’ll break down how to send Windows notifications with Lua using the FFI library to access Win32API functions.

Understanding the Challenge

Lua, by itself, does not have a built-in way to create notifications. This can be frustrating for developers looking to bring their applications to life with interactive notifications. However, thanks to the LuaJIT FFI library, we can easily invoke Windows API functions to get the job done.

Prerequisites

Before we dive in, make sure of the following:

You have LuaJIT installed on your Windows machine.

A basic understanding of Lua programming and how to run Lua scripts.

Step-by-Step Guide to Send Notifications

Here’s a comprehensive breakdown of the Lua script you’ll need to send notifications:

1. Load Necessary Libraries

To interact with the Win32API, first, you will need to load the FFI library:
