Vala

This article or section is in need of expansion.

Please add further information.

Vala is a programming language with a syntax similar to C#.

Hello World example

using GLib;

public class Hello : GLib.Object {
	public static int main (string[] args) {
		stdout.printf ("Hello world!\n");
		
		return 0;
	}
}

using GLib;

We want to use things from namespace GLib. This row is optional -- the compiler includes it anyway.

public class Hello : GLib.Object {

Now we create a new class that is derived from GLib.Object. Every class should derive from it.

    public static int main (string[] args) {

The main entry point of every Vala program is called 'main'.

        stdout.printf ("Hello world!\n");

Self-explanatory. '\n' means a new line.

        return 0;

0 means that nothing has failed.

}
}

Closing the braces.
