Hello World!

We're going to walk through the creation of a simple program using Lute. To start with, create a folder for your project with:

mkdir hello-world
cd hello-world

Create a file in this project with:

touch main.luau

Before we continue, let's ensure that we setup a good autocomplete experience for your favorite editor of choice. Run:

lute setup

This will add some files to a folder called .lute/ in your home directory. These type definition files are then made available to luau-lsp, the most popular Luau Language Server, in order to provide high quality autocomplete and typechecking.

Finally, open up the file main.luau and add:

print("Hello World")

You can now run this program by running:

lute run main.luau

or just:

lute main.luau

Note, that any Luau script can be run like this, not just a file named main.

In the next chapter, we're going to see how we can use some of the tools Lute provides to help you write some simple programs.
