How Does A Short Comment In Lua Start

Other Programming Languages

Have you ever wondered how to add a comment in Lua? Well, let me share my knowledge and guide you through the process. As a Lua enthusiast, I find comments to be incredibly helpful when it comes to documenting and understanding code. In this article, I’ll explain how a short comment in Lua starts, providing you with all the details you need to become a master of commenting in Lua.

Before diving into the syntax, let me first explain what a comment is. In programming, a comment is a piece of text that is ignored by the compiler or interpreter. It allows developers to add explanatory notes or reminders within their code without affecting its execution. Comments are an essential part of any programming language, including Lua.

In Lua, a short comment starts with a double hyphen (–). It is placed at the beginning of a line and extends until the end of that line. Let’s take a look at an example:

-- This is a short comment in Lua

As you can see, the comment starts with –, followed by the text you want to include as the comment. You can add any text after the double hyphen, and Lua will simply ignore it when executing the code.

Short comments in Lua are useful for documenting your code, providing explanations, or adding personal notes. They can help you and other developers understand the purpose and functionality of different parts of your code. By adding comments, you make your code more readable and maintainable.

It’s important to note that short comments in Lua cannot span multiple lines. If you need to add a comment that takes up multiple lines, you can simply add — at the beginning of each line. For example:

-- This is
-- a multi-line
-- comment in Lua

By using — at the beginning of each line, you can create a multi-line comment that is visually separated but still ignored by Lua when executing the code.

Now that you know how a short comment in Lua starts, it’s time to put this knowledge into practice. Start adding comments to your Lua code to enhance its clarity and maintainability. Remember, comments are not only helpful for others but also for yourself when revisiting your code.


Comments are an essential aspect of any programming language, and Lua is no exception. In Lua, a short comment starts with — and extends until the end of the line. By adding comments to your code, you can improve its readability and make it easier for others to understand. Use comments to provide explanations, document your code, and add personal notes. Happy coding!
