# Hangman Implement the logic of the hangman game using functional reactive programming. [Hangman][] is a simple word guessing game. [Functional Reactive Programming][frp] is a way to write interactive programs. It differs from the usual perspective in that instead of saying "when the button is pressed increment the counter", you write "the value of the counter is the sum of the number of times the button is pressed." Implement the basic logic behind hangman using functional reactive programming. You'll need to install an FRP library for this, this will be described in the language/track specific files of the exercise. [Hangman]: https://en.wikipedia.org/wiki/Hangman_%28game%29 [frp]: https://en.wikipedia.org/wiki/Functional_reactive_programming ## 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. ## Feedback, Issues, Pull Requests The [exercism/ocaml](https://github.com/exercism/ocaml) repository on GitHub is the home for all of the Ocaml exercises. If you have feedback about an exercise, or want to help implementing a new one, head over there and create an issue. We'll do our best to help you! ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
