Dicer
=====

A dice roller expression evaluator written in Elixir!

Installation
============

Pre-requisites
--------------

* Erlang 17 or greater
* Elixir 1.0.1
* git (to clone the repository)

Creating a command line binary
------------------------------

`mix escript.build`

From here, execute rolls like this:

`$ dicer "1+2+3"`

Running in interactive shell
----------------------------

`iex -S mix`

From here, execute rolls like this:

`iex(1)> Dicer.roll "1+2+3"`

Details
=======

Dicer is an elixir application that lets you evaluate dice rolls with simple arithmetic operators. the operators supported are `+, -, /, *`, grouping via parentheses, and designating dice via `<quantity>d<sides>` format (Ex. 20d8 or D100).

Why?
====

Because it was a fun, somewhat non-trivial way to work in Elixir.

Thanks to [Lukasz Wrobel](http://lukaszwrobel.pl/) for his [short series on parsing](http://lukaszwrobel.pl/blog/math-parser-part-1-introduction). Part 3 was my template for my code, even if it took me way too long to translate the loops into recursive function calls!
