Example repository to show what the equivalents of the Erlang/Python examples on this page look like so that they work in an Elixir/Mix application.
Currently both functionalities work, as well as calling your own Python scripts from BEAM.
git clone http://github.com/arthurcolle/elixir-snake
cd elixir-snake
source activate <name of python virtualenv>
mix deps.get
mix compile
iex -S mix run
You have to change where :python_path points to (it should point to lib/python_scripts as an absolute path on your system) in snake.ex, and other than having Python 2.7.9 installed (I used Anaconda) you should be good.
Example 1: Simple call to Python
Snake.a
iex(3)> Snake.a
"2.7.9 |Continuum Analytics, Inc.| (default, Dec 15 2014, 10:37:34) \n[GCC 4.2.1 (Apple Inc. build 5577)]"
Example 2: More complicated call to your own Python script
Snake.b
iex(2)> Snake.b
What's your name?
Arthur Colle
"Arthur Colle is a boss"
Example 3: Ouroboros - Elixir script that calls Python that calls Erlang (spawns processes)
Snake.c
iex(1)> Snake.c
You just spawned 1000 processes in BEAM VM.
Here they are!
