Hello, World in Five Languages

gal is the general abstract language: one program, compiled to five languages that don't share a type system, a memory model, or a runtime — with byte-identical output from all five.

The program

Here is the complete program, in gal.

module Hello
{
    main
    {
        say "Hello, World!";
    }
}

Compile it to Python with galpy, then run it.

$ galpy hello.txt hello.py

$ python3 hello.py
Hello, World!

Same program, JavaScript

The same source compiles to JavaScript and runs under node.

$ galjs hello.txt hello.js

$ node hello.js
Hello, World!
