nihilismus's solution to Hello World on the Standard ML track

Instructions

Test suite

Solution

The classical introductory exercise. Just say "Hello, World!".

"Hello, World!" is the traditional first program for beginning programming in a new language or environment.

The objectives are simple:

Write a function that returns the string "Hello, World!".
Run the test suite and make sure that it succeeds.
Submit your solution and check it at the website.

If everything goes well, you will be ready to fetch your first real exercise.

Loading your exercise implementation in PolyML

$ poly --use {exercise}.sml

Or:

$ poly
> use "{exercise}.sml";

Note: You have to replace {exercise}.

Running the tests

$ poly -q --use test.sml
