# Hello World
|
||
|
|
|
||
|
|
The classical introductory exercise. Just say "Hello, World!".
|
||
|
|
|
||
|
|
["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) 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.
|
||
|
|
|
||
|
|
|
||
|
|
## Getting Started
|
||
|
|
For installation and learning resources, refer to the
|
||
|
|
[exercism help page](http://exercism.io/languages/ocaml).
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
To work on the exercises, you will need `Opam` and `Core`. Consult [opam](https://opam.ocaml.org) website for instructions on how to install `opam` for your OS. Once `opam` is installed open a terminal window and run the following command to install core:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
opam install core
|
||
|
|
```
|
||
|
|
|
||
|
|
To run the tests you will need `OUnit`. Install it using `opam`:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
opam install ounit
|
||
|
|
```
|
||
|
|
|
||
|
|
## Running Tests
|
||
|
|
A Makefile is provided with a default target to compile your solution and run the tests. At the command line, type:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
make
|
||
|
|
```
|
||
|
|
|
||
|
|
## Interactive Shell
|
||
|
|
`utop` is a command line program which allows you to run Ocaml code interactively. The easiest way to install it is via opam:
|
||
|
|
```bash
|
||
|
|
opam install utop
|
||
|
|
```
|
||
|
|
Consult [utop](https://github.com/diml/utop/blob/master/README.md) for more detail.
|
||

The [exercism/ocaml](https://github.com/exercism/ocaml) repository on
|
||
|
|
GitHub is the home for all of the Ocaml exercises.
