A Gwion 'Hello, World'

Let's get started using gwion!

A simple example, step by step

We are going to write a typical Gwion Hello, World!

Prepare to make sound

In Gwion, a program typically makes sound.

Request needed plugin

Now we create a Sinusoidal generator and connect it to thee audio output (dac stands for Digital to Audio Converter) using the ~> operator.

#import Modules
new SinOsc ~> dac;

the SinOsc class comes from the Modules plugin

Greet the world

Indeed, a Hello, world has to print something.
We do so using the gack operator (<<< ... >>>)

<<< "Hello, World!" >>>;

Let time pass

Let's face it, we did not make any sound yet: No time passed, and if no time passed, there can't have been any sound. We can wait some time using

5::second => now;

Try it

Here is the complete example, editable and runnable.
Have fun!

#import Modules

<<< "Hello, World!" >>>;

new SinOsc ~> dac;

5::second => now;
