The command line interface
Now that you have installed Sabre, it is time to write our first program. This is a program that will simply print a string to the screen.
Creating a project directory
Let's begin by setting up our development workspace. Sabre really doesn't care where you store the code, so feel free to choose a different directory, than the one in this example.
mkdir ~/sources
cd ~/sources
mkdir hello_world
cd hello_world
Writing and running a program
Next, make a new source file and call it main.sb
. Sabre files should always end with .sb
by convention.
Now open the main.sb file you just created and enter the following code:
fn main() {
println("Hello, world!")
}
Save the file and go back to your terminal window. Now, run the following command to compile and run your program:
sabre run main.sb
You should see the string Hello World!
on the screen. Congrats! You have officially written a Sabre Program!
