First Program

This page walks through the smallest RayQuiro programs and shows the difference between running a script and building a native executable.

Smallest Program

print("RayQuiro CLI is live");

Save it as hello.rq and run:

rqio hello.rq

Variables And Expressions

var project = "RayQuiro";
var major = 0;
var minor = 0;
var patch = 1;

print(project, str(major) + "." + str(minor) + "." + str(patch));

Your First Function

fn sum(a, b) {
    return a + b;
}

print("7 + 5 =", sum(7, 5));

Functions are not auto-run. If you define a main() function, call it yourself:

fn main() {
    print("RayQuiro main()");
}

main();

Condition And Loop

var i = 0;

while (i < 3) {
    print("step", i);
    i = i + 1;
}

Arrays

var colors = ["red", "green", "blue"];

print(colors[0]);
print(len(colors));

Build Instead Of Run

To create a Windows executable:

rqio build hello.rq

This writes an executable into the current project's build/ directory unless you override the output with -o.

Run Through rqproject.json

If a folder contains:

• rqproject.json
• main.rq

then you can run the project by entering that folder and typing:

rqio

That is the normal workflow after:

rqio init my-app
cd my-app
rqio
