The following source code is the Ymir version of the famous program "Hello world !"

import std::io // importation of the module containing io functions

// This is a comment 

/** This is a function declaration
  * The main function, is the first one to be called
  */
def main () {
    // Print 'Hello World !!' to the console
    println ("Hello World !!");
}

A binary can be generated using GYC.

$ gyc hello.yr

This command produces a binary a.out that can be executed.

$ ./a.out
Hello World !!

The command line options of gyc are the same as those of all gcc suite compilers, with few exceptions that will be clarified in this documentation.

The option -o can be used to define the name of the output executable.

$ gyc hello.yr -o hello
$ ls
hello  hello.yr
$ ./hello
Hello World !!
