Installation

Pre-requisites

• Erlang 17 or greater

• git (to clone the repository)

Creating a command line binary

mix escript.build

From here, execute rolls like this:

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

Thanks to Lukasz Wrobel for his short series on parsing. Part 3 was my template for my code, even if it took me way too long to translate the loops into recursive function calls!
