Installation

Install Elixir, if you haven't already.

Next, follow these setup steps:

$ git clone https://github.com/rafapaez/til-elixir
$ cd til_elixir
$ mix deps.get

Usage

Run Elixir's Interactive Shell (IEx) with:

$ iex -S mix

And start playing with the repo's code. For example:

iex(1)> import TILEX.BangPipe
TILEX.BangPipe

iex(2)> {:ok, ["Welcome", "to", "TIL", "Elixir!"]} <|> Enum.join(" ")
"Welcome to TIL Elixir!"

Check any module's documentation for more code samples.

Testing

Run the tests with:

$ mix test

Note all modules and functions are tested using Doctests and ExUnit.
