Hello World

Tutorial Exercise

“Hello, World!” will get you writing some 8th and familiarize yourself with the Exercism workflow. Completing it unlocks the rest of the 8th Track.

Instructions

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:

Modify the provided code so that it produces 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.

Running and testing your solutions

From the command line

Simply type 8th test.8th. It is assumed that the 8th binary is declared in the PATH environment variable.

From a REPL

Start 8th loading test-words.8th and your solution file: 8th -f test-words.8th -f hello-world-tests.8th This will start a CLI session where you can run tests interactively by copying and pasting them in from hello-world-tests.8th or by entering your own.

Editing the hello-world-tests.8th file

This is encouraged at the beginning of your journey. Insert a back-slash space before all but the first one or two tests. Write your code to solve the first test or two. Then progressively enable more tests until you can pass all of them.
